Coronary heart disease caused by smoking
Smoking changes the composition of blood lipids, so that reduction of high-density lipoprotein, low density lipoprotein increased serum antioxidant reduced, promoting atherosclerosis, coronary heart disease incidence and development. Study abroad has long been believed that smoking is an independent risk factor for coronary heart disease. Chinese medical researchers a degree of coronary artery disease related to smoking and the findings once again confirmed this point.

PLA 61599 army out-patient department of Cardiology, Peking University People's Hospital researchers in the study of the January 1999 to December 2001 by the 1302 cases of patients with coronary angiography results and 15 risk factors for a statistical analysis of survey results, including 782 cases of coronary heart disease, 520 patients without

The study found that coronary heart disease group and non-significant difference between the lesions, lesions of smoking, years of smoking, hypertension, duration of diabetes, cholesterol, triglycerides and LDL targets, were significantly higher than those without lesions group, while high-density lipoprotein lower than those without lesions. The final statistical analysis showed that smoking and smoking age and coronary artery stenosis, extent of the lesion closely related.

Why does smoking cause coronary heart disease? Had had a number of studies suggest that: tobacco fog of carbon monoxide, nicotine and other organizations, and myocardial ischemia can induce coronary spasm, blood viscosity increased, interference with lipid metabolism, promoting cholesterol substances calm; long-term smoking can reduce the coronary blood vessel dilation and increase platelet aggregation, leading to and increased coronary artery plaque formation; smoking has changed the composition of blood lipids, so that reduction of high-density lipoprotein, low-density lipoprotein increase in serum antioxidant reduced, promoting atherosclerosis, coronary heart disease incidence and development.

Based on the above findings, the researchers again: should tobacco control as a major coronary heart disease prevention and control measures.
