Clinical types of coronary heart disease
Clinical typing is based on the World Health Organization (WHO) typing, namely: angina pectoris, myocardial infarction and sudden death; angina pectoris can be further divided into exertional angina and spontaneous angina pectoris.
(1) Exertional angina is further divided into 3 categories, one is new onset angina; second is stable exertional angina; third is worsening exertional angina.
(2) Spontaneous angina generally refers to angina attacked at rest. Among them, those who have angina attack with ST-segment elevation are called variant angina.
What kind of people are prone to coronary heart disease?
1, coronary heart disease is mostly seen in middle-aged and elderly people over 40 years old, and progresses faster after the age of 49. The onset of sudden death from myocardial infarction and coronary heart disease is directly proportional to age. There are more young male patients than young female patients, but postmenopausal women and women over the age of 60, the risk is almost equal to or even greater than that of men. Older people are more likely to have a heart attack.
2. Smokers are at least two times more likely to develop the disease than nonsmokers. This is proportional to the number of cigarettes smoked per day. In the age group of thirty-five to forty-five, the number of smokers who die from coronary artery disease is more than five times greater than the number of nonsmokers who die from coronary artery disease. Cigarettes can damage arteries, accelerate the formation of atherosclerosis and deprive the heart of oxygen.
Diet: People who often eat a higher-calorie diet, more animal fat and cholesterol are prone to the disease. At the same time, people who eat a lot of food are also prone to this disease.
3. If you have high blood pressure or diabetes, you will increase the risk of coronary artery disease. Men with diabetes are two times more likely to develop coronary artery disease than other men, and women with diabetes are five times more likely to develop coronary artery disease than other women. Having high blood pressure means that the heart has to work twice as hard. The higher the chance of a heart attack, the higher the chance of a heart attack. Elevated blood pressure is an independent risk factor for coronary heart disease. Patients with hypertension are four times more likely to suffer from the disease than those with normal blood pressure.
4, coronary heart disease has family heredity, if someone in the family suffering from coronary heart disease, more likely to have a heart attack.
5, overweight, the possibility of coronary heart disease is greater than the normal weight of people. People who are more than 20% overweight are three times more likely to have a heart attack than those who are of healthy weight.
6, if you are engaged in often sitting work, the likelihood of coronary artery disease is greater than in workers including manual labor. Lack of exercise heart is not strong people have twice the chance of a heart attack than healthy people.
7, if a woman, has been over 35 years of age, and in the use of contraceptive pills, than women using other forms of contraception are prone to coronary heart disease.
8, hyperlipidemia: due to genetic factors, or excessive fat intake, or lipid metabolism disorders resulting in dyslipidemia. Such as total cholesterol, triglycerides, low-density lipoprotein cholesterol increased and the disease, while the reduction of high-density lipoprotein susceptible to the disease. The amount of blood cholesterol should preferably be lower than 200 mg per 100 ml (5.2 mmol/L). The higher the level, the higher the risk.
9. Persistent mental stress is one of the recognized causative factors. Brain workers are greater than manual workers, and jobs that often have a sense of urgency are more likely to be diseased.
Among the above factors, high blood pressure, overweight and high cholesterol are the biggest risk factors for coronary heart disease.
How to detect coronary heart disease early?
Coronary heart disease is a common and prevalent disease among middle-aged and elderly people. People in this age group should seek medical attention in time for early detection of coronary heart disease if the following conditions occur in their daily life
(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 for 3-5 minutes during exertion or mental tension, and relieves itself after rest.
(2) Those who experience chest tightness, palpitations, or shortness of breath during physical activity, which is relieved on its own at rest.
(3) Headache, toothache, leg pain, etc. related to exercise.
(4) Those who have chest pain or palpitations during a full meal, cold or watching a thrilling movie.
(5) When sleeping at night with a low pillow, the person feels tightness in the chest and feels comfortable when lying on a high pillow; when sleeping or lying down during the day, the person suddenly has chest pain, palpitations and difficulty in breathing, which can be relieved by sitting up or standing up immediately.
(6) Heartburn, chest tightness, shortness of breath or chest pain when having sex or straining to defecate.
(7) Hearing noise will cause panic and chest tightness.
(8) Recurrent irregular pulse, unexplained tachycardia or bradycardia.
