| Introduction We are all aware of the clinical laboratory's role in assessing overall health and we are also aware that measuring a patient's serum lipids will provide some insight into their cardiovascular health. The traditional measurements of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides are the 'classic' cardiovascular risk markers.Laboratorians, and even the general public are now well-aware that LDL-C ('bad' cholesterol) concentrations should be low while HDL-C ('good' cholesterol) concentrations should be high. Triglycerides should be kept in check as well. Optimal levels are shown in the table below. So what is the risk if these values are not within optimal ranges?Cardiovascular risk can be simply defined as increasing the odds of having a pathology which affects blood flow and/or the heart. The most common cardiovascular pathology is atherosclerosis. Other cardiovascular pathologies whose odds increase as serum lipids and other cardiovascular markers become suboptimal are myocardial infarction (heart attack), stroke, congestive heart disease and coronary artery disease. Other diseases such as diabetes and the metabolic syndrome are also strongly associated with the classic cardiovascular risk markers LDL-C, HDL-C and triglycerides. | View Page |
| LpPLA2 and Cardiovascular Risk There have been dozens of clinical studies demonstrating LpPLA2's ability to predict cardiovascular risk. A 2008 study showed that people whose LpPLA2 concentrations were in the upper quartile were 1.64 times more likely to have a cardiac event than those in the lowest quartile. A meta-analysis (a study that sums the results of several other studies) performed by researchers at the Mayo Clinic showed that the unadjusted odds ratio for the association between elevated Lp-PLA2 levels and cardiovascular disease risk was 1.51, indicating that patients with elevated LpPLA2 patients had 1.51 times the risk of cardiovascular disease or events. | View Page |
