Be aware that excessive smoking may also lead to coronary heart disease. Foreign studies have long believed that smoking is an independent risk factor for coronary heart disease. A study on the relationship between smoking and the severity of coronary artery disease by Chinese medical researchers has confirmed this point again. Love smoking friends should pay attention to be alert to excessive smoking may also lead to coronary heart disease.
The results of coronary angiography and 15 risk factors in 1302 patients from January 1999 to December 2001 were statistically analyzed. 782 patients had coronary heart disease and 520 patients had no coronary heart disease.
The study found that there were significant differences between the two groups. The amount of smoking, smoking years, duration of hypertension and diabetes, cholesterol, triglyceride and low-density lipoprotein indexes in the coronary heart disease group were significantly higher than those in the non coronary heart disease group, while the high-density lipoprotein index was lower than that in the non coronary heart disease group. The final statistical analysis showed that the amount of smoking and smoking years were closely related to the degree of coronary artery stenosis and the scope of lesions.
Why does smoking cause coronary heart disease? Previous studies have suggested that carbon monoxide and nicotine in tobacco fog can cause hypoxia in tissues and myocardium, induce coronary artery spasm, increase blood viscosity, interfere with lipid metabolism, and promote cholesterol deposition; Long term smoking can reduce the function of coronary artery vasodilation, increase platelet aggregation, thus leading to and aggravating the formation of coronary atherosclerotic plaque; smoking changes the composition of blood lipids, reduces high-density lipoprotein, increases low-density lipoprotein, reduces serum antioxidant function, and promotes the occurrence and development of atherosclerosis and coronary heart disease.
According to the above results, the researchers once again proposed that smoking control should be one of the main prevention and treatment measures of coronary heart disease.
After reading the above content, we should have some understanding of the problem that excessive smoking may also cause coronary heart disease. Today we will introduce more topics about heart health. Sihai Xiaobian will continue to introduce them in the following chapters. Welcome to check. Wish you a happy life!
