What causes angina pectoris?

Under normal circumstances, angina pectoris may be caused by factors such as physical exertion, cold stimulation, anemia, hyperlipidemia, or coronary atherosclerotic heart disease. Treatment can include general management and medication under the guidance of a physician. Specific analysis is as follows:

1. Physical Exertion

During exercise, the oxygen demand of myocardial tissue increases sharply. If the coronary arteries are narrowed or have insufficient blood supply, they cannot meet the increased oxygen demand of the heart muscle, leading to angina. In daily life, individuals should immediately stop exercising, rest, and avoid emotional excitement.

2. Cold Stimulation

In cold environments, the body reduces heat loss by constricting peripheral blood vessels to maintain body temperature. This increases resistance to blood flow in the coronary arteries and reduces myocardial perfusion, potentially triggering angina. It is important to stay warm and avoid prolonged exposure to cold environments.

3. Anemia

Anemia may result from impaired hematopoietic function, heavy menstrual bleeding, trauma, or other factors. Anemia reduces the blood's oxygen-carrying capacity, leading to myocardial hypoxia and causing the aforementioned symptoms. It may be accompanied by palpitations, shortness of breath, and difficulty concentrating. Treatment under medical supervision may include medications such as ferrous sulfate tablets, folic acid tablets, and vitamin B12 injections.

4. Hyperlipidemia

Hyperlipidemia may be related to genetic factors, unhealthy lifestyle habits, or underlying diseases. Elevated lipid levels can lead to abnormal blood lipids, promote atherosclerosis, cause narrowing of the coronary arteries, and thereby induce angina. It may be associated with symptoms such as obesity and hypertension. Medications such as simvastatin dispersible tablets, fenofibrate capsules, and ezetimibe tablets should be used according to medical advice.

5. Coronary Atherosclerotic Heart Disease

This condition can be caused by factors such as dyslipidemia and hypertension. Coronary atherosclerotic heart disease may damage the endothelial cells of the coronary arteries, resulting in arterial narrowing and subsequent angina. Symptoms may include chest tightness and palpitations. Patients should take medications such as isosorbide mononitrate capsules, nifedipine tablets, and metoprolol tartrate tablets as directed by their physicians.

In daily life, it is important to maintain healthy lifestyle habits, including balanced nutrition, moderate exercise, avoidance of extreme environmental stimuli, and regular health monitoring, to support cardiovascular stability and overall health.
