The Importance of Maintaining Regular Dietary Patterns to reduce CVD risk
The Importance of Maintaining Regular Dietary Patterns to reduce CVD risk
Cardiovascular disease (CVD) is the leading cause of mortality worldwide. An estimated 17.9 million people died from some form of CVD in 2019, accounting for 32% of all-cause mortality that year1. Associations between diet and risk of cardiovascular complications have long been established, largely relating to alterations in lipid profiles.
For as long as anyone can remember, breakfast has been considered the most important meal of the day. Previous studies2 have shown an association between skipping breakfast and increased CVD risk prompting recommendations that up to 30% of one’s daily energy intake should be consumed during the first meal of the day. It has been reported that over 25% of adults skip breakfast. These individuals are often socioeconomically disadvantaged, shift workers, individuals who work particularly long hours, those who suffer from depression or those with poor health literacy2. Another study3 showed that skipping breakfast, when compared with consuming a high-energy breakfast, was associated with a 1.6x and 2.6x higher probability of non-coronary and general atherosclerosis respectively, when all other CVD risk factor had been controlled. This suggests a close relationship between eating breakfast and reducing CVD risk, however, the mechanisms and magnitude of this relationship are poorly understood.
Small, dense low-density lipoprotein cholesterol (sdLDL-C) is a smaller form of LDL-C which boasts greater propensity for uptake by arterial tissue, increased proteoglycan binding, and increased susceptibility for oxidation4. sdLDL-C concentration is strongly associated with CVD risk, yet once again, the mechanisms of this association remain enigmatic. It is thought that all of the metabolic changes associated with alterations in sdLDL-C concentration collectively contribute to the increased risk of CVD, with the main drivers being its propensity for uptake by arterial tissues and its long circulatory stability4
Skipping breakfast and sdLDL-C
A recent study investigated the relationship between skipping breakfast and the effects on lipid parameters5. In a cohort of around 28’000 people from the Japanese population, this study looked at the several markers, including sdLDL-C, to develop an understanding of the importance of regular dietary patterns for reducing the risk of CVD.
The study participants were divided into two main categories: breakfast eaters and breakfast skippers. These categories were further subdivided to differentiate men and women, over and under 55 years old, and those who eat staple products (rice, pasta, bread, etc.) and those who did not. The participants contributed blood samples which were tested for several cardiovascular biomarkers: Creatinine, Liver ALT, Total Cholesterol, Triglycerides, direct LDL-C, HDL-C and sdLDL-C.
They found that around 26% of men and 16.9% of women skipped breakfast regularly. Of these, most were considered young and had significant increases in concentration of triglycerides, LDL-C and sdLDL-C compared with those who ate breakfast almost every day.
Table 1. Median concentration of triglycerides, LDL-C, and sdLDL-C for breakfast skippers and eaters5
| Analyte | Breakfast Skippers (mg/dL) | Breakfast Eaters (mg/dL) |
| Triglycerides | 103 | 93 |
| LDL-C | 124 | 122 |
| sdLDL-C | 34.7 | 32 |
This investigation also revealed that in this cohort, 20% of men and 27.3% of women did not regularly consume staple foods as part of their diet and had higher median sdLDL-C concentration.
Table 2. Median concentration of sdLDL-C in men and women who eat or skip staple food products in their diet5
| Gender | Staple Skippers (mg/dL) | Staple Eaters (mg/dL) |
| Men | 34.1 | 31.6 |
| Women | 25.8 | 24.7 |
The data from this study supports the finding that individuals who skipped breakfast had higher sdLDL-C concentrations than those who ate breakfast consistently. Skipping breakfast can therefore be associated with troublesome lipid parameters in both genders and all age groups in the Japanese population. This study suggests that eating breakfast every day is crucial to maintain beneficial lipid parameters and reduce the risk of developing CVD.
The data also show that individuals who skipped staple foods in their meals presented with higher concentrations of sdLDL-C and a higher sdLDL-C/LDL-C ratio, in men and postmenopausal women, when compared with those who included staple foods in their meals. It is becoming increasingly common to remove staple foods from one’s diet due to their high carbohydrate content and the prevalence of low-carbohydrate diets. This data exhibits the importance of maintaining a nutritionally balanced diet to help reduce the risk of developing CVD.
As the first large scale study of its kind, this analysis provides clear insight into the increased risk of CVD associated with not only skipping breakfast, but failing to maintain a nutritionally balanced diet. The major limitation of this analysis is that it only includes individuals from the Japanese population and the same affects may not be seen in populations from other ethnicities. Therefore, further in-depth analysis is required to confirm these findings in other ethnicities

World Heart Day 2022
World Heart Day – Raising awareness of Cardiovascular Diseases
On 29th September, World Heart Day is an opportunity for everyone to stop and consider how best to use heart for humanity, for nature, and for yourself. Beating cardiovascular disease is something that matters to every beating heart.
In May 2012, world leaders committed to reducing global mortality from non-communicable diseases (NCDs) by 25% by 2025. Cardiovascular disease (CVD) is accountable for nearly half of all NCD deaths making it the world’s number one killer. World Heart Day is, therefore, the perfect platform for the CVD community to unite in the fight against CVD and reduce the global disease burden.
World Heart Day is a global campaign created by the World Heart Federation in which it informs people around the globe that CVD, including heart disease and stroke, is the world’s leading cause of death claiming 18.6 million lives each year. It aims to highlight the actions that individuals can take to prevent and control CVD as well as to drive action to educate people by controlling risk factors such as tobacco use, unhealthy diet, and physical inactivity.
What are cardiovascular diseases?
Cardiovascular diseases (CVDs) are a group of disorders relating to the heart and blood vessels and they include:
- coronary heart disease – disease of the blood vessels supplying the heart muscle
- cerebrovascular disease – disease of the blood vessels supplying the brain
- peripheral arterial disease – disease of blood vessels supplying the arms and legs
- rheumatic heart disease – damage to the heart muscle and heart valves from rheumatic fever, caused by streptococcal bacteria
- congenital heart disease – malformations of heart structure existing at birth
- deep vein thrombosis and pulmonary embolism – blood clots in the leg veins, which can dislodge and move to the heart and lungs
How can Randox help with these current global challenges
Cardiovascular disease, including heart disease, is easier to treat when detected early. Here at Randox, we utilise innovative diagnostic tests for early risk assessment capable of diagnosing disease at the earliest possible stages, because we understand that “prevention is better than cure”.
Randox Laboratories is a world leader in innovative diagnostics with 40 years’ experience and a leading provider of diagnostic reagents for the assessment of cardiovascular disease risk. Randox offer an extensive menu of cardiac biomarkers within the cardiology reagents panel including:
Risk Assessment
- CK-MB – useful in patients with chest pain; Creatine Kinase is an enzyme produced in many different types of cells, of which high levels indicate muscle trauma or damage.
- Myoglobin – a small protein which leaks out of muscle cells after injury, is also considered a biomarker for the detection of Myocardinal Infraction.
- Routine lipid tests to determine the patient’s cholesterol and triglyceride levels – HDL Cholesterol, LDL Cholesterol, Total Cholesterol and Triglycerides
- Independent risk assessment tests such as sdLDL Cholesterol and Lipoprotein(a) to determine any genetic factors which may increase their risk of CVD. Please note, this is necessary even for patients who have good cholesterol levels
- Secondary tests, such as High Sensitivity CRP, in addition to risk assessment markers and lipid evaluation – secondary tests are important in predicting future cardiac events of individuals with no previous history of CVD and those deemed healthy because of primary tests; approximately half of all heart attacks occur in patients classified as low risk. In addition, they can also be used to evaluate the risk of a recurrent cardiac event
- Homocysteine – elevated levels of homocysteine have been linked to various disease states including CVD. Extremely high levels are found in patients with homocystinuria, of which many suffer from early arteriosclerosis.

Heart Health Test
High Cholesterol is a major risk factor for heart disease and stroke therefore at Randox Health we have the Heart Health Test to keep our cholesterol at a healthy level. This is done from the convenience of your home with our home sample collection kit. Heart Health measures your total cholesterol, HDL (good) cholesterol, LDL (bad cholesterol) and triglycerides.
Why we get tested?
There is so much importance in identifying cholesterol imbalance early which allows you to make appropriate dietary and lifestyle changes which in turn reduces your risk of heart disease and stroke. It is essential to acknowledge that regardless of your age and physical health, anyone can have high cholesterol; high levels may be a result of genetics or lifestyle which can often display with no underlying symptoms. Those with a family history of heart disease, who are overweight/ obese, drink alcohol, smoke regularly, lead a sedentary lifestyle or have diabetes are at an increased risk and should get tested.

World Heart Day 2021
World Heart Day – Raising awareness of Cardiovascular Diseases
World Heart Day was established by the World Heart Federation in collaboration with the World Health Organization to raise awareness of cardiovascular diseases.
Cardiovascular disease (CVD) is the world’s number one killer, causing over 18.6 million deaths per year, according to the World Heart Federation. 85% of these deaths are due to coronary heart diseases (e.g. heart attacks) and cerebrovascular diseases (e.g. strokes) and mostly affect low-and middle-income countries.

More Information
C-reactive protein (CRP) is the dominant acute phase protein in mammals 1. Elevated levels of CRP are not disease specific but are synthesised, by hepatocytes, in response to pro-inflammatory cytokines during inflammatory and/or infectious processes 2, 3. The physiological function of CRP is the enhancement of cell-mediated immunity through the promotion of phagocytosis, accelerated chemotaxis and the activation of platelets 1.
Known as a biomarker of acute inflammation, many large-scale prospective studies demonstrate the association between CRP and chronic inflammation, including: cardiovascular disease (CVD), cerebrovascular accident (CVA) (ischaemic stroke), Alzheimer’s Disease, and age-related macular degeneration 2.
CRP is a major cardiovascular disease (CVD) risk factor. A CRP level of >10mg/l correlates with a >4% risk of developing a fatal CVD event in 10 years, including: myocardial infarction, peripheral arterial disease, stroke and sudden cardiac death. Inflammation is an integral part in the development and rapid progression of coronary heart disease (CHD) 4.
The coronary artery disease (CAD) process is characterised by increasing levels of inflammatory biomarkers. CRP is not only an excellent biomarker or mediator of atherosclerosis but is a strong independent marker in the prediction of adverse CV events, including: myocardial infarction, ischaemic stroke, and sudden cardiac death. CPR can be utilised as a clinical guide for the diagnosis, management and prognosis of CVD 5.
The development of a cerebrovascular accident (CVA) (stroke) is the result of longstanding vascular inflammation, thrombosis, plaque rupture and subsequent brain ischaemia or infarction. Elevated CRP levels is associated with the development of CVA 6.
High sensitivity CRP (hsCRP) plays an important role in the early diagnosis, prognosis, long and short death risk and prediction of etiological subtypes of stroke 7. Find out more about the Randox hsCRP assay.
Alzheimer’s disease (AD) is the most common form of dementia, accounting for 60-80% of dementia cases 7. CRP is believed to be involved in the pathophysiology of cerebral small vessel disease (CSVD) and neurodegeneration 8. CRP levels are associated with cognitive impairment 9. Inflammation should be considered as a target treatment, with the aim of delaying the progression of subclinical brain damage and cognitive decline 8. Midlife elevations in CRP are associated with an increased risk of developing AD. Patients with AD, CRP elevations continues to predict increased dementia severity suggestive of a possible pro-inflammatory endophenotype in AD 10.
In COVID-19 patients, CRP testing has proved to perform well in discriminating disease severity and predicting adverse outcomes 11. CRP levels positively correlates with lung lesions, reflecting disease severity, and should be considered a key indicator in disease monitoring (see fig. 1) 12.
CRP levels are associated with computed tomography (CT) scores and COVID-19 disease development, with CRP levels increasing in the initial stage of severe COVID-19, prior to the CT findings 13.
Elevated CRP levels have been identified in 86% of patients admitted to hospital. CRP measurements are useful in diagnosis, assessing prognosis and monitoring for clinical improvements or deterioration 14.

NOTE: sPLA2 -IIA Assay – For Research Use Only
Clinical Significance
sPLA2-llA production of fatty acids and biologically active phospholipids plays an important role in platelet, monocyte, and endothelial activation, processes known to be critical steps in atherogenesis.1
Unlike traditional cardiac biomarkers used to predict adverse outcomes in patients with acute coronary syndrome (ACS), sPLA2-llA has been shown to act at multiple pathways involved in atherogenesis, from lipid oxidation to modulation of vascular & inflammatory cell activation and apoptosis.2
Biological Significance of sPLA2-IIA
Key observations through research has found that sPLA2-llA mediated modification of lipoproteins plays a role in the development of atherosclerosis. The surface of both low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) is surrounded by phosphatidylcholine (PC) a type of phospholipid which has been scientifically proven to serve as a good extracellular target for several isoforms of sPLA2-llA. sPLA2-llA works by hydrolysing these phospholipids resulting in the production of free fatty acids and lysophophatidylcholine (LPC) which can generate pro-inflammatory actions, accelerating atherosclerosis.1
Hydrolysis of LDL-C correlates with the production of the more atherogenic, small dense LDL cholesterol (sdLDL-C). The sPLA2-llA -processed low-density lipoprotein (LDL) contains a large amount of lysophospholipids and exhibit the property of “small-dense” or “modified” LDL, which facilitates foam cell formation from macrophages. Research has shown that high plasma levels of sdLDL-C compared to less dense, larger LDL-C create a higher risk of coronary heart disease.
Cardiovascular Disease
Regular cardiovascular screening is important to ensure that cardiac risk factors are detected at the earliest possible stages. Cardiovascular disease (CVD) encompasses a number of diseases of the heart and blood vessels. Four of the main types of CVD include: coronary heart disease (CHD), cerebrovascular disease (CVA), peripheral arterial disease (PAD) and aortic disease. It is vital that at risk patients are diagnosed as quickly and efficiently as possible to ensure effective treatment plan implementation.4
The early diagnosis of CVD aids in reducing the risk of a secondary cardiovascular event and to ensure the patient receives appropriate treatment to prevent premature deaths. Early risk assessment is particularly important in people who are at a greater risk of CVD. This is evaluated through the identification of one or more risk factors including: hypertension, diabetes or hyperlipidaemia. 3 ,5
It is believed that by 2030, almost 23.6 million people will die from CVD, mainly CHD and CVA, and is projected to remain the single leading cause of death. This provides further confirmation that early diagnosis is vital to prevent and reduce the number of deaths attributed to CVD.3

Securing the future with in vitro diagnostic tests
The aim of Biomedical Science Day is to raise the public’s awareness of the importance of biomedical science and the vital role it plays in the world. Randox are dedicated to improving healthcare worldwide through placing a major focus on research and development. The Randox scientists work in pioneering research into a range of common illnesses such as cancer, cardiovascular disease and Alzheimer’s disease.
A recent blog from Doris-Ann Williams, the Chief Executive at BIVDA, explains how “increased funding is not enough to sustain the NHS” and how “we need to make better use of in vitro diagnostics to ensure a successful future”.
The National Health Service (NHS) is a publicly funded, primarily taxation, national healthcare system in the United Kingdom. It was first set-up on July 5th, 1948 by Aneurin Bevan as he believed that everyone, regardless of wealth, should have access to good healthcare. Whilst the NHS is an extremely important aspect of healthcare in the UK, in vitro diagnostics are the heart and soul of the healthcare system as healthcare professionals not only rely on blood tests to diagnose and treat patients, but also to rule out the different contributing causes to a disease state. In vitro diagnostics also plays a key role in monitoring chronic disease states. In vitro diagnostics can also aid in reducing hospital stays, reduce misdiagnosis and support patients in looking after their own health and to deliver personalised treatment plans.
The Randox scientists have developed several niche assays to improve patient diagnosis, monitor treatment and eliminate misdiagnosis.
Adiponectin
Adiponectin is a protein hormone secreted by adipocytes with anti-inflammatory and insulin-sensitising properties. It plays an important role in a number of metabolic processes including glucose regulation and fatty acid oxidation. Adiponectin levels are inversely correlated with abdominal visceral fat which have proven to be a strong predictor of several pathologies, including: metabolic syndrome, type 2 diabetes mellitus (T2DM), cancers and cardiovascular disease (CVD). For more information on the importance of testing Adiponectin levels, check out our Adiponectin Whitepaper.
Cystatin C
Cystatin C is an early risk marker for renal impairment. The most commonly run test for renal impairment is Creatinine. Creatinine measurements have proven to be inadequate as certain factors must be taken into consideration, including age, gender, ethnicity etc. The National Institute for Health and Care Excellence (NICE) have updated their guidelines, which now recommends Cystatin C as a more superior test for renal impairment due to its higher specificity for significant disease outcomes than those based on Creatinine. For more information on the importance of testing Cystatin C levels, check out our Cystatin C Whitepaper.
Small-dense LDL Cholesterol (sdLDL-C)
LDL Cholesterol (LDL-C) consists of two parts: the large and buoyant LDL Cholesterol and the small and dense LDL Cholesterol. Whilst all LDL-C transports triglycerides and cholesterol to bodily tissues, their atherogensis varies according to their size. As sdLDL-C is small and dense, they can more readily permeate the arterial wall and are more susceptible to oxidation. Research indicates that individuals with a predominance of sdLDL-C have a 3-fold increased risk of myocardial infarction. It has been noted that sdLDL-C carries less Cholesterol than large LDL, therefore a patient with predominately sdLDL-C particle may require nearly 70% more sdLDL-C particles to carry the same amount of cholesterol as the patient with predominately LDL-C particles. For more information on the importance of testing sdLDL-C levels, check out our sdLDL-C Whitepaper.
These three niche in vitro diagnostics tests developed by Randox scientists can aid in reducing NHS costs due to their higher performance compared to the traditional tests. Randox are constantly striving to improve healthcare worldwide.

Homocysteine & Women’s Health
Homocysteine is a thio-containing amino acid produced by the intracellular demethylation of methionine. Elevated levels of homocysteine (hyperhomocysteinemia) is more common in women than in men and is associated with a wide array of illnesses. It has also been proven to cause several problems in women including: cardiovascular disease (CVD), colon cancer, pregnancy complications, and birth defects.
Cardiovascular Disease
Elevated levels of circulating homocysteine correlates with an increased risk of vascular occlusion (blockage of a blood vessel). Hyperhomocysteinemia can cause inflammation of the endothelium (thin layer of cells linking the interior blood vessels). Failure to lower homocysteine levels can cause further inflammation of the arteries, veins, and capillaries causing atherosclerosis. Consequently, blood and oxygen supply to tissues is reduced, increasing the risk of cardiovascular disease. Elevated levels correlates with higher diastolic and systolic blood pressure, hypertension. However, this correlation is stronger in women than in men. Women with elevated levels of homocysteine have a 3-fold increased risk of CVD, whereas men have a 2-fold increased risk.
Colon Cancer
Women with hyperhomocysteinemia have an increased risk of colorectal cancer than women with lower levels. Women who present with the highest levels of homocysteine have more than a 70% increased colorectal cancer risk. A correlation between reduced levels of folate and increased levels of homocysteine have been found in women with colorectal adenoma. It is recommended that women with hyperhomocysteinemia and reduced levels of folate should increase their intake of fruit and vegetables to reduce their levels of homocysteine and increase their levels of folate.
Pregnancy Complications and Birth Defects
Homocysteine levels should decline during pregnancy, however, in some cases, levels increase. Hyperhomocysteinemia is associated with foetal neural tube defects which causes various conditions, characterised by placental vasculopathy, including pre-eclampsia, abruption, and recurrent pregnancy loss. It has been identified that folate supplementation can half the risk of foetal neural tube defects. One study found that hyperhomocysteinemia was associated with a 2-fold to 3-fold increased risk for pregnancy-induced hypertension, abrupyio placentae, and intrauterine growth restriction.

Women’s Health: Testing for CVD
Did you know that cardiovascular disease is the most common cause of death in women? Cardiovascular disease, or CVD, accounts for 27% of all female deaths. That’s much higher than what is commonly thought to be the biggest killer of women – breast cancer. At Randox, we’re using our innovative technology to diagnose CVD cases as early as possible so appropriate treatment can be sought.
The Randox clinical product range offers a wide range of products to combat heart issues including the RX series extensive cardiac testing panel, reagents such as H-FABP, Adiponectin an TxB Cardio and an extensive cardiac QC range available in both liquid & lyophilised format.
You can find out more about how Randox is helping to diagnose women’s health issues, such as CVD, here.
What is CVD?
Cardiovascular disease (CVD) is a general terms for conditions that affect the heart and/or blood vessels. It is usually associated with the build-up of fatty deposits in the arteries and an increased risk of blood clots.
CVD is one of the main causes of death and disability in the UK but can often largely be prevented with a healthy lifestyle.
Types of CVD
Coronary heart disease
This occurs when the flow of oxygen-rich blood to the heart muscle is blocked or reduced
Stroke
A stroke is where the blood supply to part of the brain is cut off, which can cause brain damage and possibly death. A transient ischaemic attack (also called a TIA or “mini-stroke”) is similar, but the blood flow to the brain is only temporarily disrupted.
Causes of CVD
The exact cause of CVD isn’t clear, but there are lots risk factors that can increase your risk of getting it. The more risk factors you have, the greater your chances of developing CVD. Risk factors include:
- High blood pressure
- Smoking
- High cholesterol
- Diabetes
- Inactivity
- Being overweight or obese
- Family history of CVD
- Ethnic background
Preventing CVD
- Stop smoking
- Have a balanced diet
- Exercise regularly
- Maintain a healthy weight
- Cut down alcohol consumption

Take control of your heart health with Randox
Your heart is amazing. Not only is it your most critical organ but also one of the most hard-working. The average adult heart beats around 100,000 times a day, acting as a giant pump for all the blood in your body. Indeed, every day your heart pumps over nine litres of blood through a system of blood vessels over 60,000 miles long – it’s little wonder, then, the importance placed on looking after such a vital muscle.
The heart works 24/7, only taking a rest when you sleep with the natural drop of heart rate and blood pressure. Over time, and influenced by lifestyle choices, the heart grows weaker, needing to work harder to fulfil its function. Crucial lifestyle changes now could limit your risk of developing serious cardiac conditions, such as Cardiovascular Disease (CVD) in the future. Factors which can contribute to your CVD risk include genes inherited from parents or grandparents, smoking, an unhealthy diet, excessive alcohol consumption and low physical activity levels.
You can’t change your DNA, but you can find out what it means to you and your family. One of our advanced tests can identify people living with a common but often hidden disorder – Familial Hypercholesterolemia (FH). Fewer than 12% of people in the UK know they have this potentially fatal condition. It is characterised by dangerously high levels of cholesterol which can lead to early onset cardiovascular disease.
While lifestyle changes may help to limit your risk of CVD, and related heart condition, it is impossible to eradicate it completely for everyone. Accounting for 31% of deaths worldwide, CVD is the number one cause of death globally but early screening could lower this figure significantly. That’s why it’s vitally important to detect CVD early before a coronary event like a heart attack occurs.
Today in the UK, 530 people will go to the hospital with a suspected heart attack. Only a fifth of these people will actually be having a heart attack. According to a team from King’s College London, as reported by the BBC, a faster, more accurate diagnosis of whether chest pain is caused by a heart attack would save the health service millions of pounds each year by sending well patients home and freeing up beds. Yet current testing methods do not efficiently differentiate between high-risk patients and the estimated 80% of patients who are not having a heart attack.
Randox’s revolutionary test for Heart-Type Fatty Acid-Binding Protein (H-FABP), when combined with current testing, is able to rule out a heart attack for patients who present at A&E with chest pain which is caused by other conditions such as respiratory issues, meaning they may not need emergency admission.
When measured at the time a patient presents to A&E with chest pain, H-FABP enables doctors to triage patients suffering with a heart attack more efficiently than before, making sure those at high-risk are given medical intervention earlier.
Early screening in the form of a comprehensive health check is essential to detect cardiac irregularities before they become serious problems. Heart damage builds up over time, meaning that when detected early enough, lifestyle changes can help to reduce cardiac risk and potentially even prevent a cardiac event occurring.
Therefore, it is vitally important that individuals are tested for CVD to detect them in the earliest stages to reduce damage, prevent further damage, or even death. Furthermore, many people suffer from inherited cardiac risk factors, which stresses the need for accurate testing.
Randox offer the complete laboratory solution to cardiac risk assessment information to doctors and hospitals, and also directly to the public at Randox Health. Our range of both traditional and novel cardiac risk biomarkers, along with our technologically-advanced range of analysers, serves to allow us to offer the most advanced, most accurate health check available on the planet.
As well as your cardiovascular risk score, a Randox Health check will also assess your cholesterol levels, FH risk, triglycerides, creative kinase, myoglobin, troponin levels and many more heart health indicators. In total, a Randox Health check can assess up to 350 different markers of irregularity or disease in the whole body, from heart to hormone health and skin to stomach.
Many serious future health issues are preventable now with action. Find out more about our health check programmes here.

Celebrating Valentine’s Day with the Cardiac Prediction Array from Randox Biosciences
With Valentine’s Day being in the heart of National Heart Month, Randox Biosciences want to take this opportunity to talk about the importance of looking after your heart and the awareness of the tests out there currently on offer.
The British Health Foundation launched National Heart Month with the aim to spread awareness of heart disease and to encourage the nation to make small changes towards a healthier lifestyle.
Currently Coronary Heart Disease (CHD) is the leading cause of death in the UK, with 73,000 people dying from Coronary Heart Disease every year in the UK.1
Coronary Heart Disease is a disease in which plaque builds up inside the coronary arteries. Our arteries supply oxygen-rich blood to the heart muscles, however, over time plaque builds up and can harden. This hardened plaque, then narrows the coronary arteries reducing the flow of oxygen-rich blood to the heart, which can lead to angina or a heart attack to occur.2
CHD is more likely with increasing age, in men rather than in women before menopause and if close relatives have suffered CHD early in life. These risk factors cannot be changed, however, there are other risk factors that can be modified. These are known as elevated blood cholesterol, overweight and obesity, smoking, lack of physical activity, unhealthy diet and stress.
You can prevent and control many CHD risk factors with heart-healthy changes and medication. There is only a few risk factors that can’t be controlled such as your age, gender and family history. Nonetheless, many lifestyle changes help control several CHD risk factors at the same time, such as physical activity which may reduce stress, lower your blood pressure, help control diabetes and help control your weight.
If you believe you are at risk of coronary heart disease, you can ask for a risk assessment for heart diseases, heart attack or stroke. However, current CHD risk assessment tools based on common risk factors such as blood pressure and blood cholesterol levels have low predictive value and take no account of genetic predisposition to CHD.
In recent years, Genome Wide Association Studies (GWAS) have been carried out to identify genetics variants associated with CHD. Meta-analysis of such studies has identified 19 variants as being associated with CHD.
Individually, the presence of an “at risk” variant does not greatly increase the risk of developing CHD. However, the presence of multiple “at risk” alleles can increase the risk of developing CHD two-fold or greater an effect similar to being a current smoker. Combining genotype information with common risk factors could allow individuals to be more accurately classified therefore preventative therapies and lifestyle advice can be targeted to those who require it most.
In order to utilise the GWAS findings within a clinical setting, individuals require to be genotyped for each of the 19 CHD “at risk” SNPs. However, at present this can be a time consuming and expensive process.
Together with key opinion leaders in cardiovascular genetics, Randox has developed the Cardiac Risk Prediction Array which will allow all 19 SNPs to be genotyped simultaneously, which incorporates a test to identify patients predisposed to statin induced myopathy.
Firstly, a multiplex PCR reaction is performed, where the products amplified correspond to the genotype of the patient sample. The PCR products are then hybridised onto the Cardiac Risk Prediction biochip array and imaged using the Evidence Investigator analyser to identify which PCR products are present. Patient samples can be genotyped within 1 day.
This Heart Month, we are urging the pubic to not only help raise awareness of heart disease but also educate themselves on the signs and symptoms to increase early diagnosis. As a global diagnostic company, Randox Biosciences are committed to the ongoing development of diagnostic tests, as well as our research into numerous disease areas to improve health worldwide.
