First, autumn cardiovascular diseases are prone to autumn is the season of cardiovascular diseases, it is easy to trigger the original cardiovascular system diseases, according to the relevant data reported that the late autumn and early winter, hypertension, cerebral thrombosis, cerebral hemorrhage, myocardial infarction, heart failure incidence is much higher than other seasons. Second, autumn cardiovascular disease prone to cause: as the weather becomes cooler, the skin and subcutaneous tissue vasoconstriction, peripheral vascular resistance increases, resulting in higher blood pressure. Cold can also increase the concentration of blood fibrin, causing blood viscosity, leading to thrombosis. The cold can also cause coronary artery spasm, which directly affects the blood supply to the heart and induces angina pectoris or myocardial infarction. At the same time, autumn temperature changes, easy to catch a cold and secondary respiratory infections, thus triggering, aggravating cardiovascular disease. The autumn wind and leaves, miserable wind and rain, so that the elderly easily produce a sense of twilight, inducing negative emotions, serious, depressed all day long, less lazy, easy to suffer from depression. In addition, the weather becomes cooler, people’s appetite increases, such as uncontrolled also easy to cause overweight, endangering heart health. Third, how to prevent: prevention of cardiovascular disease can start from two aspects, one to have a full understanding of the disease they suffer from, to avoid the idea of light “enemy”, the second to pay attention to and understand the weather, listen to the weather forecast in time, so that you can always increase or decrease clothing, to cope with. If you do a good job in the fall, you will lay a good and solid foundation for comprehensive prevention in the winter. At the same time, moderate exercise, weight control, ensure sleep, emotional moderation, will keep blood sugar, blood lipids, blood pressure up to standard, then the risk of coronary heart disease will be greatly reduced. The temperature difference between day and night in autumn, the body’s vasoconstriction and diastole changes, blood pressure is prone to fluctuations, which is one of the main triggers of cardiac insufficiency. The more serious cardiovascular disease is cardiac insufficiency, patients with cardiac insufficiency, in addition to the autumn to pay more attention to the treatment of primary diseases (i.e. diseases causing cardiac insufficiency such as coronary heart disease, hypertensive heart disease, rheumatic heart disease, pulmonary heart disease, etc.), the treatment of cardiac insufficiency (such as cardiac strengthening, diuretic, vasodilator), but also pay attention to the following matters: ① Prevention of various infections. Infections are the primary cause of heart failure, and because of the poor resistance of heart failure patients, special attention should be paid to infections, such as respiratory infections (cold and fever, pharyngitis, bronchitis, pneumonia, etc.), urinary tract infections (common in female patients), and so on. Especially in late autumn, it is very easy to suffer from colds. ② Avoid medium-intensity physical activities to reduce the burden on the heart. ③Emotions should not be overly excited. Emotional excitement can cause sympathetic excitement, resulting in a faster heartbeat and an increased heart burden. ④Strictly control the intake of salt. Excessive salt intake in the diet is the “enemy” of heart disorders, but too little salt intake does not meet the body’s needs and can lead to additional diseases (such as hyponatremia). How much salt intake is appropriate? It is generally limited to about 5 grams per day for mild patients, and moderately reduced for moderate to severe patients. ⑤ Do not give intravenous fluids too fast and too much. ⑥Symptoms such as heartburn, chest tightness and breath-holding should be treated early. (7) Do not abuse cardiovascular system drugs, and follow medical advice. Because some drugs can inhibit the contraction of the heart muscle, the common ones are benzoin, betalactam, reserpine, quinidine, isoptin, compound antihypertensive tablets, etc. should be noted.
