The harm of second-hand smoke to patients with coronary heart disease

Smoking is the main risk factor for the occurrence of coronary heart disease, and epidemiological surveys in China show that the incidence of coronary heart disease is more than 26 times higher than that of non-smoking patients. Inhalation of second-hand smoke is equally harmful, and second-hand smoke is no less harmful to passive smokers than active smokers, especially for people suffering from cardiovascular disease. Secondhand smoke contains carbon monoxide, and the carbon monoxide in second-hand smoke smoke can bind to hemoglobin, which will greatly hinder the combination of hemoglobin and oxygen. Causing hypoxia in the human body and triggering myocardial infarction, this is undoubtedly worse for patients with cardiovascular and cerebrovascular diseases. The dangers of nicotine in second-hand smoke. After the nicotine in second-hand smoke enters the human body, it will cause the body's blood vessels to constrict, which will make the heartbeat faster, the blood pressure rise, and also cause the blood to be viscous. Patients with myocardial infarction, hyperlipidemia, hypertension, etc. are more likely to deteriorate. Several components of second-hand smoke can cause severe cardiovascular poisoning, disrupt the normal function of the heart, blood and vascular system, and increase the risk of cardiovascular events. Exposure to secondhand smoke can also exacerbate the extent of heart attacks and increase the risk of recurrence and death. Usually pay more attention to eating vitamin-rich vegetables and fruits, providing sufficient high-quality protein, and paying attention to the appropriate amount of exercise to resist the harm of second-hand smoke. At the same time, we advocate that everyone stay away from smoking sources and create a comfortable environment for themselves.
