The triggers of angina attacks are diverse and vary from person to person. Here are some common triggers:
- Physical activity: Exertion, excessive exercise, lifting heavy objects, climbing stairs, and going uphill may cause angina attacks. Angina caused by physical exertion usually occurs after intense exercise or prolonged maintenance of a single position.
- Emotional excitement: Mood swings such as anger, anxiety, tension, fear, and watching intense sports events may trigger angina attacks.
- Overfeeding: Eating too much or a high-fat meal can concentrate blood supply in the gastrointestinal tract, resulting in relative insufficient blood supply to the heart, which may induce angina attacks.
- Constipation: During forced bowel movements, increased abdominal pressure and backflow of blood can exacerbate the heart’s burden, possibly triggering angina attacks.
- Cold stimulation: Sudden drops in temperature, especially when walking against the wind or performing outdoor work, may cause angina attacks.
- Smoking and drinking: Nicotine and alcohol in tobacco and alcohol stimulate faster heart rate and increased blood pressure, which increases the burden on the heart and may induce angina attacks.
- Psychological factors: Prolonged mental stress, anxiety, and depression may also trigger angina attacks.
- Insufficient sleep: Insomnia, poor sleep quality, and stay up late may lead to angina attacks.
- Drug side effects: Certain medications such as Propranolol, Metoprolol, and Hydrochlorothiazide may cause angina attacks.
- recumbent angina pectoris: some patients have angina pectoris in a quiet lying flat state, such as sleep at night and lunch break, suggesting severe multivessel coronary artery obstructive disease and prone to myocardial infarction.
It should be noted that the triggers of angina attacks may vary among individuals. Understanding your own angina triggers and avoiding these factors can significantly control angina attacks. Regular physical examinations, following doctor’s advice, rational medication use, and improving living habits are also essential measures for preventing angina attacks.
