Top Bio-Markers For Heart Disease
Homocystine, Theoretically, an elevated level of homocysteine in the blood (hyperhomocysteinemia) is believed to cause narrowing and hardening of the arteries (atherosclerosis). This narrowing and hardening of the vessels is thought to occur through a variety of ways involving elevated homocysteine. The blood vessel narrowing in turn leads to diminished blood flow through the affected arteries. Elevated levels of homocysteine in the blood may also increase the tendency to excessive blood clotting. Blood clots inside the arteries can further diminish the flow of blood. The resultant lack of blood supply to the heart muscles may cause heart attacks, and the lack of blood supply to the brain causes strokes. Elevated homocysteine levels also have been shown to be associated with formation of blood clots in veins (deep vein thrombosis and pulmonary embolism).
Blood Sugar; Lowering blood sugar levels could reduce the risk of coronary heart disease in both diabetics and non-diabetics, according to researchers at the Johns Hopkins Bloomberg School of Public Health and other institutions. The researchers found that Hemoglobin A1c (HbA1c)-a measure of long-term blood glucose level-predicts heart disease risk in both diabetics and non-diabetics. An elevated blood glucose level is the defining feature of diabetes, but until now it was unclear whether elevated glucose levels contributed independently to increasing heart-disease risk. The study is published in the September 12, 2005, issue of Archives of Internal Medicine.
