The Complete Solution to Cardiac Risk Assessment
“CVDs are the number 1 cause of death globally: more people die annually from CVDs than from any other cause”. In 2015, roughly 17.7 million people died from CVD, representing 31% of all global deaths: 7.4 million were due to coronary heart disease and 6.7 million were due to stroke. (WHO, 2017)
Cardiac health and regular cardiovascular screening is important to enable risk factors to be detected in their earliest stages. There are a few factors which contribute to CVD. These include: smoking, unhealthy diet, excessive alcohol consumption, low physical activity levels. Whilst there are only a few factors contributing to CVD, these can be maintained by the patient through living a healthy lifestyle including: quitting smoking, consuming no more than the recommended allowance of alcohol, cutting out junk food, and exercising for 30 minutes a day, 3 – 5 days a week. In a perfect world, this would be easy and CVD would not be a global problem. However, due to busy lifestyles, cravings, reduced willpower, and convenience, not all individuals in today’s world will be able to avoid CVDs. Therefore, it is vitally important that individuals are tested for CVDs to detect them in the earliest stages to reduce damage, prevent further damage, or even death. Furthermore, many individuals suffer from inherited cardiac risk factors, which stresses the need for accurate testing of both traditional and novel cardiac risk biomarkers.
Randox offer the complete solution to cardiac risk assessment including: RX analysers, traditional and novel reagents, internal quality control (Acusera), and external quality control (RIQAS).
Randox has developed the RX series range of clinical chemistry analysers for high-quality semi-automated and fully automated testing. Choose between the RX misano, RX monaco, RX daytona+, RX imola, and the RX modena depending on the throughput of your laboratory. The RX series offers a suitable analyser for your laboratory’s needs.

As previously mentioned, early assessment of cardiac risk is vital. Randox offer a range of novel risk biomarkers for both very early and the genetic assessment of cardiac risk.
The niche Adiponectin assay allows for the early assessment of CVD. Adiponectin levels are inversely correlated with abdominal visceral fat which has proven to be a strong predictor of T2DM. Body-Mass Index (BMI) is a common method for determining which patients are classified as underweight, healthy, overweight or obese, however, BMI does not take into account gender, ethnicity or activity levels. For example, measuring the BMI of athletes who have a high BMI due to muscle weighing heavier than fat would classify them as obese which is inaccurate. Measuring adiponectin levels is therefore a much more reliable indicator of at-risk patients compared to BMI.
LDL cholesterol is often referred to as the ‘bad cholesterol’. High concentrations of LDL-cholesterol is considered to be the most important clinical predictor, of all single parameters, with respect to coronary atherosclerosis. However, sLDL is a smaller, more dense subfraction of LDL-cholesterol. sLDL particles more readily permeate the inner arterial wall and are more susceptible to oxidation. Individuals with a predominance of sLDL have a 3-fold increased risk of myocardial infarction. Measurement of sLDL allows the clinician to get a more comprehensive picture of lipid risk factors and tailor treatment accordingly.
Elevated levels of Lp(a) are considered to be both a casual risk factor and independent genetic marker of atherosclerotic disorders. The major challenge associated with Lp(a) measurement is the size variation of apo(a) within Lp(a). Dependent upon the size of apo(a) in the assay calibrator, many assays under or overestimate apo(a) size in the patient sample. Numerous commercially available products suffer apo(a) size related bias, resulting in an over estimation of Lp(a) in samples with large apo(a)molecules and an under estimation in samples with small apo(a) molecules. The antibody used in the Randox method detects the complete Lp(a) molecule providing accurate and consistent results. This was proven by the IFCC who developed a gold standard ELISA reference assay and compared 22 commercially available tests. The Randox Lp(a) method displayed the least (minimal) amount of apo(a) size related bias, proving it be a superior offering.
HDL3 Cholesterol is a smaller and more dense subfraction of the HDL particle. HDL is the scavenger of cholesterol within arterial walls and the levels of HDL3 is too low, the ability to remove this cholesterol is reduced. Therefore, it is widely accepted that there is an inverse correlation between HDL3 and CVD risk.

Do you want to have optimal brain function later in life? We do. The majority of people focus on keeping their bodies in optimal condition but often forget about the most important organ, the brain. With more of us living until we’re much older, reduced brain function and Alzheimer’s are becoming increasingly more common; it is one of the most feared consequences of aging. We expect our bodies to age due to wear and tear; however there are easy ways to slow it, you will be glad to hear. Here are some top tips to keep your brain health at its peak.
- Get physical exercise
It is becoming an increasingly well-known fact by scientists that regular exercise may be the single most important thing you can do to ensure optimum brain health. The reason for this is that exercise increases the blood supply to your brain so therefore increases your brain capacity. Experts advise 30 minutes of exercise every other day to ensure good mental health. Exercise also helps with cholesterol levels, mental stress and diabetes.
- Eat, eat, eat
Good nutrition is also essential for good brain health. Your brain is no different to any other organ: the better the fuel it receives; the better it works, simple. As with everything it is important to keep your calories in check as it has been proven to reduce mental illness. We aim to reduce the consumption of saturated fats and cholesterol as these can decrease brain function. No matter who you are, vitamins are also very important to ensure not only a healthy brain, but a healthy body. Vitamins of particular importance are folic acid, B6 and B12 which it is well-known can help lower your homocysteine levels. There is an ever-growing body of research which suggests that homocysteine levels have a strong correlation with Alzheimer’s and dementia. If you would like to read more about the link between homocysteine and Alzheimer’s, check out our previous blog post ‘How important is homocysteine research for Alzheimer’s disease?’
- Get enough sleep
Recent studies have suggested that a poor sleeping pattern is linked with cognitive decline in old age. A good night’s rest can actually double the chances of finding creative solutions to problems faced in everyday life! It has been proven that when we don’t sleep, proteins build up on the brain. These proteins build on the synapses, making it hard to think and learn new information; which is not conducive to good brain health.
Relaxation is key in a healthy lifestyle. Stress has a negative impact on the brain. It creates harmful chemicals to flow over areas of the brain that are in control of memory. Too much of these chemicals can lead to dementia and other memory loss related diseases, so maybe it’s not such a bad idea that you take that trip to the Bahamas you were thinking about!
- Improve you cholesterol
Cholesterol is commonly split up into good cholesterol (HDL) and bad cholesterol (LDL). There are loads of ways to improve your cholesterol levels such as exercise, weight control, dieting and avoiding tobacco. It is very important to keep you levels of LDL down as high levels can increase the risk of Alzheimer’s, dementia and cardiac problems in old age. At Randox we are constantly coming up with new and exciting ways of monitoring your cholesterol and the launch of our new HDL3 test is coming soon. For more information on HDL3, check it out here!
- Brain exercises
Challenging your mind from time to time is important for good brain health; it keeps your brain active and uses cognitive thought to try and learn or solve a problem. It is thought that a lack of education is a strong influence in cognitive decline. Challenging your brain improves memory, develops critical thinking and stimulates the whole brain ensuring brain health is kept to a maximum. It can often be done in fun ways like brain teasers, puzzles and jigsaws. Check out our recent brain teaser here!
These are only some of the ways in which to keep your brain in peak condition. Aging will take a toll on everyone and it is impossible to avoid; however these 6 techniques can help maintain optimal brain function! We have been keeping up to date with Alzheimer’s in celebration of World Alzheimer’s Month. Remember a healthy brain is the key to success!
