What causes angina? What are the causes of angina in young people?

Causes of angina. Clause.

First, it is high blood pressure. Clause.

Second, it is hyperlipidemia, including elevated cholesterol and triglycerides. Third, diabetes. Fourth, smoking.

Fifth, obesity. Sixth, it is too old, too little physical work, and too much mental work. In short, under the action of the above risk factors, it can lead to coronary atherosclerosis and lumen stenosis of the heart, resulting in myocardial ischemia and hypoxia.

Therefore, the prevention of coronary heart disease should first start with the adjustment of the above risk factors, adopt measures such as low-salt and low-fat diet, quit smoking, limit alcohol, appropriate exercise, and cooperate with corresponding drugs, which can effectively prevent the further aggravation of angina.

The direct cause of angina pectoris is due to the absolute or relative insufficiency of myocardial blood supply, so various reasons for reducing myocardial blood ** or increasing oxygen consumption can induce angina. In general, the lack of blood supply to the heart muscle is mainly due to coronary heart disease, and sometimes other types of heart disease or some high blood pressure can also cause angina. In daily life, the cause of angina pectoris is generally caused by excessive physical labor, which consumes the person's oxygen.

In addition, abnormal emotional agitation, full meals, fright, and excessive cold can also induce angina. Angina pectoris is usually triggered in these cases, but there are also some people who have angina pectoris when eating, dressing, or having bowel movements.

There are many causes of angina, the most common is that hemoconcentration will cause angina, some patients in order to be able to reduce the number of urine, before going to bed and at night dare not drink water, plus some people's kidney concentration function is relatively poor, nocturia is more, resulting in blood concentration and viscosity increases the resistance of circulation, aggravates the load of the heart, thereby causing angina.

Angina pectoris** in older adults include:

1. Coronary atherosclerosis causes fixed luminal stenosis (often more than 75%);

2. Coronary artery spasm such as variant angina;

3. Other coronary artery lesions: such as inflammation, embolism or congenital malformations;

4. Non-coronary artery lesions: such as aortic stenosis or aortic insufficiency, syphilitic aoritis, severe anemia, hyperthyroidism, paroxysmal tachycardia;

6. Hypertrophic cardiomyopathy, mitral valve prolapse, etc. Among them, the most important is coronary heart disease, i.e. coronary atherosclerotic stenosis and/or coronary artery spasm; Five: low blood pressure, increased blood viscosity or slow blood flow.
