The association between lipid disorders and heart disease is well known. Medical checkups usually involve measurements of cholesterol and other lipid parameters, and most doctors advise their patients on how to improve their lipid pattern. Dietary interventions to lower the risk of heart disease commonly aim at reducing blood levels of cholesterol, LDL cholesterol in particular. This is […]
Do Lipid Biomarkers Like Cholesterol Predict Cancer Risk?
Lipid biomarkers are frequently used to assess the risk of heart disease. A simple blood test provides information about LDL-cholesterol (LDL-C) (1), commonly nicknamed the bad cholesterol and HDL-cholesterol (HDL-C) (2), often called the good cholesterol. Triglycerides are usually measured as well (3). For many different reasons, lowering LDL-C has become a primary target for the prevention of heart disease. Evidence […]
Ferritin – High and Low Ferritin Explained
Ferritin is a protein found in the cells of most living organisms. It binds to iron and plays a major role in storing iron in the human body. Iron a is an important part of hemoglobin, a protein molecule that carries oxygen in red blood cells and delivers it to the cells of the body. The body […]
Familial Hypercholesterolemia (FH) is Not Detected by Measuring Cholesterol
Elevated blood cholesterol is a common reason why people see their doctor. Most of us have been told that high cholesterol increases the risk of cardiovascular disease, and we are usually urged to lower it by any means available.

Cardiovascular Risk Factors and Age: Is it all about the cholesterol?
For decades, scientists have been trying to find out what causes heart disease. Although we have gained some knowledge along the way, many questions remain unanswered. Instead of providing clear answers, scientific research often raises a set of new issues that have to be addressed. The American physicist, Thomas S. Kuhn wrote that “to be scientific is among […]
Erectile Dysfunction (Impotence) – Impotence Explained

Fructose – The Role of Fructose in Metabolic Syndrome and Heart Disease
Mark already ignores me. I think it is because I am in bed and I am a ‘stationary’ object, because once or twice at home when he saw me up and on the way to the toilet he evinced great interest at once. I am absolutely determined to check myself in any tendency to be […]
Low-Density Lipoprotein (LDL) in Atherosclerosis and Heart Disease
The death rate from coronary artery disease (CAD) has declined considerably over the last three decades, mostly because of better control of risk factors and advances in therapy. However, due to the aging of the population and better survival of those affected, the prevalence of the disease remains high. The current epidemic of obesity and type 2 diabetes will likely escalate the problem further. Atherosclerosis, […]
Carotid Intima-Media Thickness (CIMT)
Carotid intima-media thickness (CIMT) is a relatively simple, noninvasive measure that uses ultrasound to detect the presence and extent of atherosclerosis in an artery. Atherosclerosis, the underlying cause of coronary heart disease is characterized by an accumulation of lipids, white blood cells and cell debris in the inner layers of the arterial wall. Atherosclerotic plaques may cause blockages in […]
High Triglycerides – How to Lower Triglycerides
Triglycerides are important organic compounds. Most of the fat we consume in our diet is triglyceride and so too is most of the fat we store in our body. Fatty acids contained in triglycerides are an essential source of energy for our cells. Triglyceride concentration can be measured in blood and may provide valuable information about metabolism and general health. High levels may reflect […]
Low-Carb Diet to Treat Non-Alcoholic Fatty Liver Disease – Does It Make Sense?

The disease is not contagious, and unlike many other disorders of the liver, it is not caused by overconsumption of alcohol. It is called non-alcoholic fatty liver disease (NAFLD) and has become the leading cause of chronic liver disease […]

If we ask for advice, there are likely to be dozen different answers. So, in the era of information overflow, the general population, has become severely confused. Apart from having to choose […]
Broken Heart Syndrome (Stress Cardiomyopathy)
Emotional stress is a known risk factor for developing heart disease (1). Never is this relationship more evident than in the broken heart syndrome, an acute heart disorder that is directly precipitated and caused by an emotionally stressful event. The broken heart syndrome, also called stress cardiomyopathy (stress-induced cardiomyopathy), apical ballooning syndrome, or takotsubo cardiomyopathy […]
Saturated Fat Back in the Gutter; Failing to see the bigger picture
Saturated fat is the bad boy once again according to a paper recently published online in the Journal of the American College of Cardiology (1). The authors of the paper, led by Li Yanping from the Department of Nutrition at the Harvard School of Public Health, conclude that unsaturated fatty acids, especially polyunsaturated fatty acids (PUFAs) […]
