What are the early symptoms of heart disease?

I believe many people are familiar with the disease of heart disease. This disease is more common in older people. Any disease will have some milder symptoms when it shows obvious symptoms. Many people do not understand the early symptoms of heart disease and do not know how to treat it. So, what are the early symptoms of heart disease?

First, what are the early symptoms of coronary heart disease? Coronary heart disease is the abbreviation of coronary atherosclerotic heart disease. It refers to a type of heart disease in which the coronary arteries, the blood vessels that supply nutrients to the heart, suffer from severe atherosclerosis or spasm, causing narrowing or blockage of the coronary arteries, and thrombosis causing occlusion of the lumen, leading to myocardial ischemia, hypoxia or infarction. It is also called ischemic heart disease. Coronary heart disease is the most common type of organ disease caused by atherosclerosis and is also a common disease that endangers the health of middle-aged and elderly people. The occurrence of this disease is closely related to the degree and number of coronary artery stenosis due to atherosclerosis. However, a small number of young patients may develop the disease even though their coronary atherosclerosis is not severe or even without atherosclerosis. There are also some elderly people who have severe coronary atherosclerotic stenosis but do not necessarily have clinical manifestations of coronary heart disease such as chest pain and palpitations. Therefore, the pathogenesis of coronary heart disease is very complex. Generally speaking, organic type is more common, and coronary artery spasm also often occurs in coronary arteries with atherosclerosis.

Second, the disease mostly occurs after the age of 40, more often in men than in women, more in mental workers than in manual workers, and more in cities than in rural areas. The average prevalence rate is about 6.49%, and the prevalence rate increases with age. It is the most common cardiovascular disease in the elderly. With the improvement of people's living standards, the prevalence of coronary heart disease in my country is currently increasing year by year, and the age of patients tends to be younger. Therefore, in the 21st century, my country faces the challenge of cardiovascular disease. Whether it can curb the "number one killer" that endangers human health depends on prevention.

What are the risk factors for coronary heart disease? As medical scientists conduct extensive and in-depth research on coronary heart disease, it is shown that this disease is a multifactorial disease caused by multiple factors acting at different links. These factors are susceptibility factors, or risk factors, mainly including: 1) Age: This disease is more common in middle-aged and elderly people over 40 years old, and progresses faster after 49 years old. The incidence of myocardial infarction and sudden death from coronary heart disease is proportional to age. In recent years, the incidence of coronary heart disease has tended to be younger. (2) Gender: Among multiple ethnic groups in the United States, the coronary heart disease mortality rate among men is significantly higher than that among women. According to statistics from 1979, the mortality rate of coronary heart disease among white males aged 35 to 44 was 5.2 times that of females. In our country, the male-to-female ratio is about 2:1. However, after menopause, the estrogen level in women drops significantly, while LDL increases. At this time, the incidence of coronary heart disease in women increases significantly. Some data show that after the age of 60, the incidence rate in women is higher than that in men.

What are the early symptoms of heart disease? Occupation: Those who do mental work are more likely to suffer from heart disease than those who do physical work and those who often have a sense of urgency in their work. Diet: People who often eat high-calorie diets, more animal fat and cholesterol are prone to this disease. At the same time, people who eat a lot are also more susceptible to this disease. Researchers in Germany, the world's most obese country, believe that "people get fat because they eat too much." Therefore, to control the incidence of coronary heart disease, in addition to controlling the intake of high-fat foods, it is also necessary to pay attention to controlling food intake. Blood lipids: Abnormal blood lipids may be caused by genetic factors, excessive fat intake, or lipid metabolism disorders. If total cholesterol, triglycerides, LDL, and VLDL increase, while HDL decreases, one is prone to this disease. Blood pressure: Increased blood pressure is an independent risk factor for coronary heart disease. The most common hazards caused by atherosclerosis due to high blood pressure are the coronary arteries and cerebral arteries. 60% to 70% of patients with coronary atherosclerosis have hypertension, and the incidence of this disease in hypertensive patients is four times that of those with normal blood pressure. Smoking: Smoking is a major risk factor for coronary heart disease. Compared with non-smokers, the incidence and mortality of this disease in smokers are 2 to 6 times higher, and are directly proportional to the number of cigarettes smoked per day. Obesity: People who are overweight (10% overweight is mild, 20% overweight is moderate, and 30% overweight is severe) are prone to this disease, especially those who gain weight rapidly. However, it is currently believed that more attention should be paid to studying methods for evaluating body weight. Don't just look at the body mass index, but measure the thickness of subcutaneous fat. Existing prospective research data show that people with central obesity are at greater risk.
