What Is Angina Pectoris?

　　The term “angina pectoris” (literally “strangling pain in the chest”) often evokes an image of intense, severe pain—almost as if the heart itself is being constricted. Literally interpreted, it suggests a serious, debilitating pain that typically causes significant discomfort to the patient. The primary sensation experienced by patients is a sharp, acute pain localized behind the sternum. But what exactly is angina pectoris?

　　What Is Angina Pectoris?

　　Angina pectoris is a clinical syndrome characterized primarily by acute chest pain or discomfort resulting from insufficient coronary artery blood supply and consequent acute myocardial ischemia and hypoxia. Following an angina episode, patients commonly experience distinct symptoms—typically paroxysmal chest pain or a sensation of pressure, often accompanied by additional symptoms. The pain is predominantly located behind the sternum. Angina pectoris is more prevalent among men, especially those aged around 40 years. Common precipitating factors include physical exertion, emotional stress, dietary indiscretions, upper respiratory infections (e.g., colds), rainy weather, and acute circulatory failure.

　　Preventing angina pectoris requires adopting a healthier lifestyle: maintaining a regular daily routine, avoiding late-night activities, ensuring adequate sleep, abstaining from smoking, limiting alcohol consumption, paying attention to dietary habits—such as avoiding excessively fatty foods, increasing intake of fresh fruits and vegetables, adhering to a low-fat, low-salt diet, and minimizing consumption of pickled or preserved foods. While engaging in physical activity, ensure adequate nutritional intake to support metabolic demands. Cultivate a positive mindset, manage stress effectively, avoid anxiety and tension, and practice appropriate self-regulation. Undergo regular health check-ups, seek prompt medical attention for any unusual symptoms, and make timely adjustments to maintain optimal health and prevent angina pectoris.

　　In daily life, maintain disciplined eating habits: avoid spicy and irritating foods, refrain from binge eating or overeating, and eliminate late-night activities.
