The rainy season is characterized by continuous rain, high temperature, high humidity and low air pressure, which is unique to Jiangnan and is also a season of high incidence of cardiovascular diseases. It can trigger or aggravate various cardiovascular diseases such as hypertension, coronary heart disease, atrial fibrillation, rheumatic heart disease, etc. The latest medical statistics show that the incidence of cardiovascular disease in this season is increasing year by year, forming a second “peak period” outside of winter. Therefore, during the rainy season, we should pay scientific attention to the prevention and treatment of cardiovascular diseases, do not delay the best time for treatment, and strive for early detection and early treatment to take care of health, smoothly through the rainy season and avoid serious cardiovascular events. During the rainy season, because of the hot and humid environment, the weather is sultry and unbearable, the human body is very easy to sweat, the blood viscosity increases, coronary heart patients themselves because of coronary artery atherosclerosis, poor blood supply, it is easy to occur again myocardial ischemia, chest tightness, angina symptoms, and in severe cases, even myocardial infarction, heart failure, etc. leading to death, thus in this season, patients with coronary heart disease should pay attention to: 1. good Living habits and control of related diseases: more active control of blood pressure, monitoring blood sugar, regulation of blood lipids, quit smoking and limit alcohol, reduce body weight, good regular life, ensure adequate sleep and regulate emotions. Because the rainy season is a season of high humidity and humidity, low temperature and rain, many humidity and heat, if you do not pay attention to the adjustment of bad habits and control of related diseases, coronary heart disease is very easy to develop. 2, according to their own conditions, follow medical advice, standardize the use of cardiovascular disease medication, do not arbitrarily and irregularly discontinue the use of drugs. 3, always carry with you to relieve angina medication: such as musk heart pills, quick-acting heart pills, nitroglycerin, heartburn and other drugs, if necessary, sublingual, and can be used repeatedly according to the condition, for more adequate rescue time, because the rescue time for coronary heart disease is very important 4, adjust the bad diet, scientific diet: avoid eating animal offal, fried food, animal oil, fatty meat, meat sausage, fish roe The following are some of the most important things to avoid: avoid eating animal offal, fried foods, animal oil, fatty meat, meat sausages, fish roe, squid, egg yolk, whole milk powder, cheese, desserts, etc.; eat less nuts, processed juice drinks; low-salt diet: bean paste, salted vegetables as much as possible; eat more fresh fruits and vegetables, mixed grains; daily lean meat control at about 75 grams. 5, the acute onset of response: once the symptoms worsen or change, you should promptly seek medical advice. At present, many tertiary hospitals have corresponding “green channel”. Under the arrangement of doctors, through electrocardiogram, myocardial markers, advanced non-invasive coronary CT examination and, if necessary, more accurate coronary angiography, a clear diagnosis and risk stratification can be made. And among them time is very important for coronary artery disease salvage. For patients with diagnosed coronary artery disease, on the basis of regular medication such as coronary dilation anti-anginal and antiplatelet medication, further percutaneous coronary stenting or coronary artery bypass grafting can be used for salvage according to the condition and the doctor’s decision.
