As we enter the height of summer, many people believe that the cold winter months are the high season for cardiovascular disease and that the hot summer months are much safer for cardiovascular patients. In fact, many tragedies remind us that if cardiovascular patients are paralyzed in the summer, it can lead to very serious consequences as well. Cardiovascular disease is a chronic disease, and since the 1990s, the seasonality of cardiovascular disease onset has become increasingly blurred. In winter, the cold stimulates the body circulation vasoconstriction, heart rate accelerates, blood pressure rises, and myocardial oxygen consumption increases easily induced myocardial ischemia, which can induce acute myocardial infarction in severe cases. Similarly, the hot weather in summer, the human metabolism accelerates, the heart rate accelerates, which will also increase myocardial oxygen consumption, coupled with sweating leads to a decrease in blood volume, blood pressure viscosity increases and heat dissipation leads to the expansion of body capillaries, reducing the amount of return blood, but also easy to induce myocardial ischemia. Since summer has such a great impact on cardiovascular disease patients, of course, patients should be careful to prevent tragedies. Scientific heart care, should pay attention to the following seven elements: a. Avoid overwork Acute myocardial infarction is an important cause of sudden cardiac death. Modern people, especially young people, life is stressful, fast-paced work, excessive busyness, exertion is very easy to make people in a state of sub-health disease, and even “overworked”. Second, the emotional stability of the summer heat, long days and short nights, prone to lack of sleep, sleep quality, emotional irritability and even plant nervous disorders, resulting in sinus tachycardia, premature ventricular beats and other arrhythmias. In addition, emotional excitement, great joy and sadness can stimulate sympathetic excitation leading to increased myocardial oxygen consumption, coronary artery spasm, and other serious cases can induce life-threatening myocardial infarction. Third, reasonable drinking water summer people generally sweat more, hydration is very important. Not paying attention to hydration will lead to blood concentration and increased viscosity to form thrombosis. Heart failure patients such as a large amount of water in a short period of time, water can quickly enter the blood circulation, increasing the burden on the heart induced heart failure. Therefore, it is recommended that cardiovascular patients hydrate a small number of times, hydration to plain water is appropriate, you can drink a moderate amount of mung bean soup, chrysanthemum tea, etc.. For patients with hypertension, hyperlipidemia, coronary heart disease and other cardiovascular diseases should control total dietary calories, reduce body weight, avoid coffee, strong tea, chili peppers and other stimulating foods, and limit the intake of sucrose and sugar-containing foods. Advocate a light diet, eat more fresh vegetables and fruits, eat lean meat, fish, black fungus, soy products, etc., and try to use vegetable oil as cooking oil. Eat less animal fat, fatty meat, animal offal, brain, egg yolk, roe, etc. You should quit smoking and limit alcohol to keep your bowels open. Five, quality sleep Only adequate sleep can ensure the normal functioning of the human body functions. Good sleep can make the respiratory heartbeat stable, reduce the burden on the heart and reduce heart attacks. In summer, many people sleep late and get up early, coupled with sweating, the brain blood supply is relatively reduced, easy to make people depressed, therefore, it is recommended that cardiovascular patients try to ensure early to bed, early to rise, appropriate nap at noon, to half an hour is appropriate. If sleep disorders occur, you can take sedative-hypnotic drugs to improve sleep under the guidance of a doctor if necessary. Six, moderate exercise in summer many people have a fondness for morning exercise. It should be noted that 4:00 a.m. D10:00 a.m. is the high incidence of cardiovascular diseases. The reason is that the morning blood viscosity is high, platelet complex aggregation is high, coronary artery tension is high and easy to spasm, prone to myocardial ischemia and myocardial infarction. You should avoid exercising during this time, you can exercise in the evening after the sun sets, for half an hour to an hour, according to your ability, the exercise should not be too intense to avoid danger. Seven, follow the instructions to take medication Some patients with hypertension in the summer will have a certain degree of blood pressure decline, and even a part of mild hypertension patients can maintain blood pressure in the normal range after stopping medication. Some patients do need to adjust their antihypertensive medication in summer, but patients are reminded not to stop or reduce their medication on their own. Patients should closely monitor their blood pressure changes and record them, and adjust their antihypertensive medications according to their doctor’s recommendations. Some patients with cardiovascular disease also believe that they can discontinue their lipid-lowering medications because they have a poor appetite and eat less in summer. It should be noted that some patients with coronary heart disease or peripheral atherosclerosis take “statin” lipid-lowering drugs, which not only lower blood lipids, but also have the effect of anti-atherosclerosis and stabilizing and reversing plaque. Therefore, you can’t just stop using antihypertensive and lipid-lowering drugs in summer, especially statins for coronary heart disease patients must be taken for a long time. Finally, remind cardiovascular disease patients, if you travel in summer, in addition to pay attention to heat, you should bring daily oral aspirin, antihypertensive and lipid-lowering drugs, at the same time should carry nitroglycerin, quick-acting heart pills and other emergency drugs, once the chest pain attack, immediately stop all sports, sublingual the above drugs, promptly by themselves or ask others to contact the emergency center, so as not to delay the rescue time.
