The incidence of heart disease is increasing, and the trend is younger, the prevention of heart disease needs to attract the attention of families and society as a whole. Ninety percent of heart disease is formed artificially, bad habits endanger heart health: obesity: obesity makes the body need more circulating blood volume, increasing the load on the heart, easy to cause myocardial strain, heart function is reduced, and excessive obesity can lead to sudden cardiac death. Smoking: Many people know that smoking and lung cancer are closely related, but they do not know that smoking is also one of the risk factors for coronary heart disease. Nicotine in tobacco can make the coronary arteries spasm, leading to myocardial ischemia and myocardial infarction in severe cases. Alcohol abuse: Drinking alcohol and heart health say different things, moderate drinking is good for the heart, from mild vasodilation, reduce the load on the heart; but heavy drinking, alcohol direct loss of myocardium, causing myocardial lesions, affecting the contractile function of the heart. Overexertion: behind the death of overwork is mostly heart disease. When overworked, the body is in a state of mental tension, sympathetic nerves are overexcited, heart rate is accelerated blood pressure is increased, myocardial oxygen consumption is increased, which leads to insufficient blood supply to the heart, and even triggers sudden death. Extreme lack of exercise: people living in the same environment, often sitting still, suffering from coronary heart disease is higher than those who are often active. Exercise can induce the small blood vessels of the heart to expand, lengthen and increase, improve the oxygen supply to the heart muscle, improve the metabolism of the heart muscle, and improve the working capacity of the heart muscle and the metabolic function of the heart. Sleep deprivation: Chronic sleep deprivation can put stress on your heart and increase the risk of cardiovascular disease and death. The reasons for this are unclear, but researchers say that sleep deprivation can lead to increased blood pressure, which increases the risk of heart disease and stroke.
