| Atherosclerosis continued If a plaque ruptures it will expose sub-endothelial tissue to blood cells and in so doing stimulate the formation of a clot. The clot is the body's attempt to seal off the crack but the clot itself can cause further obstruction to blood flow. This sudden increase in the blockage caused by the raised ruptured plaque and associated clot can transform a mild blockage into a critical one within a matter of hours. If it occurs within the blood vessels of the heart, the decrease in blood flow leads to severe and prolonged chest pain known as unstable angina. Such a patient is at obvious risk for a myocardial infarct should the blockage become any worse.Atherosclerosis typically begins in early adolescence, and is found in most major arteries but since it is asymptomatic during the early half of life we need cardiovascualr risk markers to help assess patient risk. If an at-risk patient is identified early, the hope is that medication, lifestyle changes or medical procedures can be used to avert a serious cardiovascular event. So, although the vast majority of us have some degree of atherosclerosis, risk markers can help identify those among us who are in more imminent danger or who have increased risk of an adverse cardiovascular event. | View Page |
| Adult Treatment Panel How do physicians interpret risk marker results? Assuming the laboratory offers, and physicians order, cardiovascular risk marker tests, how are these results used? The National Cholesterol Education Program periodically assembles scientists and physicians to create lipid treatment guidelines for patients. These panels are referred to as the Adult Treatment Panel (ATP). The third assembly of the ATP did not give specific guidelines regarding risk marker use in patients but they did acknowledge their potential utility. The general consensus is that novel cardiovascular risk markers should be used in selected patients, such as those who already have significant risk factors (hypertension, smoking, obesity, etc.) or in patients who have family histories of cardiovascular disease. The value in using risk markers is that they will not only uncover cardiovascular risk but they can also be used to motivate patients to alter lifestyle and diet. It is expected that as these emerging cardiovascular risk markers continue to be validated in clinical studies, they will become very useful and perhaps even be part of a new standard of care for patients.If risk marker levels can be correlated to treatment strategies, physicians will find them especially useful in tracking patient success. | View Page |
