The incidence of coronary heart disease is increasing year by year, and there is a trend of youthfulness. If not detected early, paid attention early and treated early, myocardial infarction or even sudden death can occur, and the famous sketch actor Gao Xiumin is a tragic example. First, how to detect coronary heart disease early? A common symptom of coronary heart disease is angina, but many angina symptoms are not typical and should be identified early so that coronary heart disease can be detected as early as possible, if you have the following symptoms, you should seek medical attention as soon as possible. (1) Dull pain behind the sternum or in the precordial region or tightness-like pain that radiates to the left shoulder or left upper arm when exertion or mental stress occurs, lasting 3-5 minutes and relieving on its own after rest. (2) Those who develop chest tightness, palpitations, shortness of breath, and weakness during physical activity, which are relieved by themselves at rest. (3) Those who develop exercise-related headache, toothache, jaw pain, etc. (4) Those who develop chest pain and palpitations during a full meal, cold or watching a thrilling movie. (5)When sleeping at night with a low pillow, you feel tightness in your chest and need to lie down with a high pillow to feel comfortable; when sleeping or lying down during the day, you have sudden chest pain, palpitations and difficulty in breathing, which can be relieved by sitting up or standing up immediately. (6) Panic, chest tightness, shortness of breath or chest pain during sexual intercourse or forceful defecation. (7) Hearing noise will cause panic and chest tightness. (8) Recurrent irregular pulse, unexplained tachycardia or bradycardia. A small number of patients are asymptomatic even though they are very ill. Therefore, coronary heart disease with atypical symptoms is often overlooked by people. Director Tang Zhongren suggests that all middle-aged and elderly patients who have the above-mentioned manifestations and have risk factors for coronary heart disease such as obesity, smoking, hypertension and work stress should visit the hospital as early as possible. Doctors will choose electrocardiogram, cardiac ultrasound, myocardial enzymology, coronary angiography and other tests for patients according to their conditions in order to evaluate their conditions and choose a reasonable treatment plan early. Second, why should patients with coronary heart disease pay attention to their condition early? Due to the regulation and compensatory function of the body, many patients with coronary heart disease are usually no different from normal people, however, their hearts are very fragile, once they encounter factors such as fatigue, emotional excitement and other factors that increase the load on the heart beyond the compensatory capacity of the body, heart attack and sudden death will occur in just a few minutes, which can be described as a lifeline. And in recent years, more and more coronary heart disease occurs in the middle-aged people who are rich and strong, shouldering the two burdens of career and family, they are more likely to be busy with various matters and neglect their hearts, so more and more tragedies happen around us. Director Tang Zhongren pointed out that due to the core position of heart in maintaining life and the special nature of coronary heart disease, patients with coronary heart disease must pay attention to their condition as early as possible. Third, why should patients with coronary heart disease be treated early? There is a famous saying in cardiovascular science, “Time is heart muscle, time is life”. Director Tang Zhongren pointed out that it is not terrible to have coronary heart disease, what is terrible is not to take appropriate treatment in time. In particular, patients who have recently developed angina pectoris and whose symptoms have worsened, should seek medical attention in time to avoid developing acute myocardial infarction and missing the opportunity for treatment. Although the unpredictability of coronary heart disease and the high mortality and disability rates of coronary heart disease, modern medical technology has already mastered a large number of effective means of treating coronary heart disease, such as drug therapy, interventional therapy and surgery, which can significantly improve the prognosis of coronary heart disease patients as long as appropriate treatment is taken in a timely manner.
