Introduction
Angina pectoris is a symptom of coronary artery disease caused by narrowing of the coronary arteries, which supply blood to the myocardium. Typically, the most common symptom is a pressure-like pain located behind or over the sternum, which may radiate to the inner aspect of the left upper arm, neck, scapular region, jaw, and other areas. When the heart requires increased blood flow, the narrowed arteries are unable to meet this demand, resulting in pain and chest tightness.
Nowadays, individuals face considerable pressure from daily life and work—pressure that adversely affects physical health and may even trigger angina pectoris.
What Is Angina Pectoris?
Angina pectoris results from narrowing of the coronary arteries—the vessels supplying blood to the heart muscle—and is a hallmark symptom of coronary artery disease (CAD). Typically, the most common manifestation is a constricting or pressure-like pain behind or over the sternum, which may radiate to the inner left arm, neck, scapular region, jaw, or other areas. When the heart’s demand for blood increases—such as during exertion or emotional stress—the narrowed arteries cannot deliver sufficient oxygenated blood, leading to chest pain and tightness. Patients with severe coronary artery disease must exercise particular caution. Prompt medical evaluation and treatment are strongly advised; otherwise, untreated angina may progress to acute myocardial infarction—a potentially life-threatening condition.
Patients with angina pectoris should adopt a rational dietary regimen: control total caloric intake to maintain a healthy body weight. Overweight or obese individuals should further reduce daily caloric intake and consume low-fat, low-cholesterol foods. Dietary fat should constitute no more than 30% of total calories—including no more than 10% from animal fats—and alcohol and high-sugar foods should be limited. A light, balanced diet is recommended, emphasizing foods rich in vitamin C and plant-based proteins—such as fresh vegetables, melons and gourds, fruits, and legumes. Preferred cooking oils include peanut oil, soybean oil, and rapeseed oil. Fish, poultry, lean meats, dairy products, and soy-based protein sources are encouraged. Binge eating should be strictly avoided, as it may precipitate angina attacks or even myocardial infarction.
Patients are advised to avoid strenuous physical activity, adhere to a low-salt, low-fat diet, ensure adequate sleep, manage anxiety, and thereby reduce the frequency of angina episodes. We hope this information proves helpful.
