Recently, with the continuous high temperature weather in summer, it has posed a potential threat to people's health. In hot weather, the human heart rate accelerates, fluid loss occurs, and the heart load increases, which in turn increases the risk of thrombosis and can easily trigger myocardial infarction (hereinafter referred to as myocardial infarction). Liu Yanxia, the director of the general medicine department of the General Hospital of the Northern Warfare Zone of the Chinese People's Liberation Army, told reporters that if the high temperature continues in summer, we should be careful to induce myocardial infarction.
Why is summer prone to heart attacks? Liu Yanxia introduced that in hot weather, the dilation of blood vessels in the human body causes a decrease in blood pressure, an increase in heart burden, and fluid loss. If water is not replenished in a timely manner, it can cause dehydration, which in turn increases the formation of blood clots and blocks coronary arteries, easily leading to heart attacks. At the same time, the hot and dry weather on summer nights can easily affect people's sleep quality, and a lack of sufficient rest can lead to inadequate recovery of the cardiovascular system, increasing the risk of acute myocardial infarction. In addition, people often use air conditioning or cold drinks to cool down in summer. The temperature changes of one cold and one hot can easily cause vasospasm, affecting the blood supply to the heart and leading to myocardial infarction.
How to effectively prevent heart attacks in daily life during hot weather? Liu Yanxia suggests avoiding sudden cold and heat. Before entering an air-conditioned room, transition to the door for a period of time to allow the body to gradually adapt to the temperature difference. Avoid direct air conditioning and prevent blood vessels from suddenly contracting or expanding; In hot weather, the human body is prone to sweating, so it is necessary to replenish water in small amounts and multiple times. You can choose to drink warm water or diluted salt water to maintain the balance of water and electrolytes in the body; In terms of diet, a light diet should be the main focus, reducing the intake of high oil, high-fat, and high salt foods, eating more fresh vegetables and fruits, foods rich in dietary fiber, and avoiding excessive consumption of cold drinks to avoid stimulating the gastrointestinal tract and triggering heart attacks; Stable coronary heart disease patients can choose to engage in moderate exercise in the evening, usually for 30 to 45 minutes, such as walking, Tai Chi, etc., and try to avoid morning exercise as much as possible; Ensure sufficient sleep time every day, avoid staying up late and overexertion, advocate napping, but it is not advisable to go to bed immediately after lunch, and the time should not exceed 1 hour. In addition, people with cardiovascular and cerebrovascular diseases should follow medical advice and not stop taking medication at will, especially antihypertensive and lipid-lowering drugs.
What symptoms indicate a heart attack? Liu Yanxia pointed out that when the following symptoms occur, it should be highly suspected to be a heart attack: chest pain, manifested as compressive and suffocating pain, lasting for more than 15 minutes and requiring vigilance, often accompanied by symptoms such as near death, sweating profusely, restlessness, and fear; Before a heart attack occurs, there may be repeated episodes of post activity angina or short-term chest tightness, which can be relieved by resting for 5-20 minutes, with alternating episodes and relief; Other atypical symptoms include jaw pain, left arm pain, abdominal pain, nausea, vomiting, etc. In addition, patients may experience pain in the throat and teeth, or changes in consciousness and systemic symptoms such as fever and tachycardia, and should seek medical attention immediately.
In addition, Liu Yanxia suggests that if chest pain occurs for a long time and cannot be relieved, do not have a sense of luck and immediately call the 120 emergency hotline. At the same time, be careful not to take medication indiscriminately. Nitroglycerin is a vasodilator that can cause a decrease in blood pressure after use. Therefore, before taking nitroglycerin, it is important to ensure that there is no hypotension. When an acute myocardial infarction occurs, do not designate a hospital for treatment. The golden emergency time for myocardial infarction is about 2 hours, so do not waste time. Follow the instructions of the rescue personnel and go to the nearest hospital with conditions for diagnosis and treatment to avoid delaying the treatment opportunity.
