Thrombogenic and lipid risk factors in hypertension and coronary artery disease

Abstract

Hypertension is not solely a phenomenon of elevation of systemic blood pressure. It frequently occurs in association with a great deal of metabolic derangement's and should never be regarded as coincidental only. Furthermore, a knowledge of these metabolic derangements may provide a clue to unveil the underlying mechanisms how essential hypertension and its associated complications arise. Therefore we devoted our attention to platelet dysfunction and dyslipidemia which are closely associated with atherosclerosis-the commonest complication of hypertension. We found there exists enhanced platelet aggregation in essential hypertension and a variety of its associated atherosclerotic diseases. Such an aberration in platelet function may be modified after administration of antihypertensive medications such as angiotensin converting enzyme (ACE) inhibitors, calcium channel blockades, β blockades and dietary manipulation. We also demonstrated the close association between hypertension and its associated atherosclerotic complications and abnormal lipids profile. Hypertriglyceridemia which was initially regarded unimportant in the pathogenesis of atherosclerosis is found to be closely related to hypertension. In an intensive review, we found that people in Taiwan has experienced a huge increase in dietary calories and total fat consumption. In order to solve this emerging problem, a national guideline for diagnosis and management of lipid disorders in Taiwan was developed and announced. Through these efforts, we hope we can reduce the cardiovascular morbidity and mortality in Taiwan and even extend our experience to other countries.
