What are the characteristics of typical angina symptoms? 1, pain site and range: for the anterior chest area (behind the sternal body), often accompanied by the left shoulder, neck, arm radiating pain. The range of pain in the precordial region is usually the size of the palm of your hand. 2. Nature of pain: mostly crush-like pain, pressure, stuffiness or tightness, often accompanied by anxiety or fear of dying. Because activity can exacerbate myocardial ischemia, typical angina attacks mostly require the cessation of activity, and walking patients show a forced stop. 3, duration: more than a few minutes or more than ten minutes, usually no more than half an hour. 4, relief mode: most patients can be relieved within a few minutes after rest, or within a few minutes after taking nitroglycerin or heart pills. 5. Causes: Generally, it occurs during physical activity (such as constipation, rapid walking, heavy lifting, climbing or physical labor, etc.), emotional excitement, cold, and full meals. It can also occur during rest and sleep. If you have any of these features, you should pay enough attention and seek medical attention as soon as possible. Even if only some of the characteristics match, you should consult a cardiologist for a comprehensive analysis and decision on further examination.
