Triggers of Angina

　　Nowadays, frequent late-night work and study have exerted significant negative effects on people’s health, weakening their immune systems and disrupting endocrine and exocrine functions. Angina pectoris is a relatively common condition associated with these lifestyle factors—so what triggers angina?

　　Triggers of Angina Pectoris

　　Common triggers of angina include physical exertion, emotional stress, and upper respiratory infections (e.g., the common cold). In individuals with pre-existing fixed stenosis or partial occlusion of the coronary arteries, resting myocardial blood supply may remain sufficient to meet baseline cardiac demands—hence no symptoms occur at rest. However, under provoking conditions such as physical exertion, emotional excitement, or exposure to cold, cardiac workload increases. The coronary arteries—already compromised—cannot adequately augment blood flow to meet the heightened oxygen demand of the myocardium, potentially precipitating an angina attack.

       Patients diagnosed with angina should adhere strictly to prescribed cardiac medications during weekdays to prevent disease progression. It is recommended that they take lipid-lowering agents and plaque-stabilizing drugs. Additionally, patients should actively modify and improve their lifestyle—including regular exercise for weight management, smoking cessation, alcohol abstinence, and adoption of a low-salt, low-fat diet.

　　Patients are advised to maintain a positive and relaxed mood. They should avoid consuming cold, spicy, or high-fat foods. We hope this information proves helpful to you.
