In late summer, the heat has not dissipated. Nourish and protect the heart, do not let up
2023-08-30
At the end of summer, the heat did not dissipate. The temperature difference gradually increases in the morning and evening, and in such an environment, vulnerable cardiovascular disease patients need to be more vigilant about "high-risk moments". According to hospital statistics over the years, for every 1 ℃ increase in temperature, the number of patients with cardiovascular and cerebrovascular diseases seeking emergency treatment increases by 17.3%. In areas with high population density, influenced by the urban heat island effect, the night is also stuffy and hot. Patients with cardiovascular diseases should not underestimate the residual heat of summer heat. Ten groups of people are more prone to cardiovascular diseases. In high-temperature environments, the body's metabolism significantly accelerates. In order to dissipate heat, the body's surface blood vessels expand, leading to more blood circulation to the body's surface, and the heart's blood supply is relatively reduced. High temperatures can also stimulate the sympathetic nervous system, accelerate heart rate, and constrict coronary arteries, thereby increasing the burden on the heart. In addition, the human body sweats a lot, and a large amount of water in the body evaporates through sweat, causing an increase in blood viscosity, which is prone to platelet aggregation and thrombosis, leading to myocardial infarction. In daily life, the following 10 groups of people are more prone to developing cardiovascular diseases and need to be vigilant: people who have previously suffered from cardiovascular and cerebrovascular diseases; People aged 65 and above, especially the elderly; Long term outdoor working population; People who have been sitting in the office for a long time blowing air conditioning; People who do not like drinking water; People who enjoy pouring cold drinks fiercely; People who enjoy taking cold showers; A group of heavy flavored people who enjoy spicy and stimulating flavors; People who like to stay up late; People who do not like sports, etc. To protect the heart, it is necessary to prevent cardiovascular diseases before they occur. Here are a few things to do to help the heart withstand the test of temperature. Don't be careless and feel stuffy in the chest. Hot and stuffy weather can easily make people suffocate. Many patients with myocardial infarction may experience symptoms of palpitations, suffocation, chest pain, and fatigue 3 to 4 days before the onset of the disease. Especially for the elderly, they should be extra vigilant. If they feel discomfort such as chest tightness on hot days, they must seek medical attention in a timely manner. Patients with coronary heart disease should avoid taking cold baths. When the body sweats a lot, the capillaries of the skin are mostly in a dilated state. If you suddenly take a cold shower at this time, it will stimulate vasoconstriction and cause discomfort symptoms such as palpitations and chest pain. People with coronary heart disease should pay special attention. Taking a cold shower can increase the body's burden, induce myocardial ischemia, and lead to angina and even myocardial infarction. Be wary of excessive temperature difference between indoor and outdoor areas. Sudden changes from a cool room with air conditioning to a stuffy outdoor environment can cause the human cardiovascular system to suddenly relax. On the contrary, when suddenly entering a cool room from a stuffy outdoor environment, blood vessels will suddenly contract. This can cause excessive blood pressure fluctuations, leading to myocardial infarction. It is recommended to set the indoor air conditioning temperature at 26 ℃, and the indoor and outdoor temperature difference is less than 8 ℃. When entering and exiting an air-conditioned room, you can first stand at the door for a while to provide a buffer for the body and also provide the heart with an adaptation process. After turning on the air conditioning for a period of time, remember to ventilate and maintain fresh indoor air. When the human body sweats a lot, it is necessary to replenish water in a timely manner. Otherwise, the blood viscosity increases, the blood flow speed slows down, and the risk of thrombosis increases, leading to moderate diseases such as angina, myocardial infarction, and stroke. Patients with cardiovascular diseases should pay special attention and avoid drinking beverages containing caffeine and alcohol, which can worsen dehydration. Follow medical advice and do not stop taking medication on your own. Some patients may feel hot during the day
