Countries have already studies suggest that smoking is an independent risk factor for coronary heart disease. Our medical researchers a study on smoking and the severity of coronary lesions results again confirmed this.
PLA 61,599 troops outpatient department with Peking University People’s Hospital, Department of Cardiology, researchers conducted a statistical analysis in the study of January 1999 to December 2001, 1302 patients the results of coronary angiography and 15 risk factors findings made 782 cases of coronary heart disease, 520 cases of coronary heart disease.
The study found significant differences between coronary heart disease group and no lesions, lesions of smoking, years of smoking, hypertension and duration of diabetes, cholesterol, triglycerides and low-density lipoprotein indicators, no lesion group were significantly higher than , high-density lipoprotein lower than non-lesion group. Final statistical analysis showed that the amount of smoking and years of smoking is closely related to coronary artery stenosis, extent of disease.
Smoking Why cause coronary heart disease? Previously there have been a number of studies that: the tobacco fog of carbon monoxide, nicotine, and other organizations and myocardial hypoxia can be induced coronary spasm, increased blood viscosity, interfere with lipid metabolism, promote cholesterol substances calm; Long-term smoking can reduce coronary vascular expansion function, increased platelet aggregation, leading to aggravate the formation of coronary plaques; smoking has changed the composition of lipids, to reduce the high-density lipoprotein, low density lipoprotein increased, decreased serum antioxidant effects, promotes artery sclerosis, coronary heart disease occurrence and development.
According to the results of the study, the researchers again proposed: one should control smoking as coronary heart disease prevention and control measures.
