Health tips: a few days ago, after investigation and research, scientists finally summed up 9 independent risk factors leading to coronary heart disease. Smoking ranked second, next to hyperlipidemia, ranking higher than hypertension and diabetes. Now we all attach great importance to lowering blood pressure, blood sugar and blood fat, but we don't think so about quitting smoking.
Less than 30% of respondents know that smoking causes coronary heart disease
Unfortunately, most Chinese still lack the understanding of the relationship between tobacco dependence and coronary heart disease. According to the results of the national epidemiological survey on smoking in 2002, less than 30% of the respondents realized that smokers are prone to coronary heart disease. By contrast, about 70% of respondents have realized that smoking can cause lung cancer. In fact, among the causes of death of smokers in China, coronary heart disease ranks third only after chronic obstructive pulmonary disease (COPD) and lung cancer. In foreign countries, more smokers die of coronary heart disease than lung cancer.
In fact, the harm of tobacco to blood vessels has been proved by modern medicine. Experts pointed out: 'tobacco can lead to coronary heart disease in many ways. For example, normal vascular endothelium can secrete nitric oxide. Smoking can affect the secretion of this substance, and then affect the vasodilation function. Smoking can also promote platelet aggregation and thrombosis. As a result, smokers have a much higher risk of developing coronary heart disease.
The best way to reduce the mortality of coronary heart disease is to quit smoking
There are many risk factors for coronary heart disease and myocardial infarction, ranging from diabetes, hypertension, hyperlipidemia to obesity and smoking. However, among these heart health killers, what's the ranking of smoking? "Scientists have summarized nine independent risk factors for coronary heart disease. Smoking ranks second, second only to hyperlipidemia, and higher than hypertension and diabetes. Now we all attach great importance to lowering blood pressure, blood sugar and blood fat, but we don't think so about quitting smoking. Experts point out that many patients suffer from myocardial infarction before they are 50 years old. Their blood pressure is not high, their blood sugar is not high, and they are not even obese. The only explanation is that they smoke a lot. '
If patients with coronary heart disease quit smoking, the mortality can be reduced by 36%, if taking statins and other drugs to reduce cholesterol, the mortality can be reduced by 29%, if taking & beta; receptor blockers or ACEI drugs, the mortality can be reduced by 23%. In comparison, if coronary heart disease patients want to reduce mortality, the best way is to quit smoking. '
Quitting smoking saves money
Studies have shown that the cardiovascular system can change gradually after quitting smoking, and some reactions can even be described as immediate. To be specific. From the last cigarette smoking, blood pressure drops within 20 minutes, body temperature and heart rate return to normal; within 24 hours, the risk of myocardial infarction begins to decrease; within one year, the risk of coronary heart disease can be reduced by 50%; within five years after quitting smoking, the risk of stroke or cerebral hemorrhage can be reduced to a level similar to that of non-smokers; Within 15 years of quitting smoking, the risk of coronary heart disease can eventually be reduced to a level similar to that of non-smokers. Moreover, foreign medical and economic studies show that smoking cessation is the most economical intervention for coronary heart disease compared with the control of blood pressure, blood glucose and blood lipid.
At the Great Wall meeting, experts also pointed out the need to pay more attention to 'second-hand smoke'. At the same time, the relationship between 'second-hand smoke' and coronary heart disease has been confirmed in China. In order to prevent coronary heart disease, it is necessary to protect non-smokers from passive smoking.
