Common symptoms of heart disease can include chest pain or a feeling of pressure or heaviness in the chest, shortness of breath, unusual tiredness, dizziness, palpitations (feeling that the heart is racing or skipping beats), and sometimes pain that spreads to the arm, neck, jaw, or back. Some people, especially older adults and people with diabetes, may have milder or less typical symptoms like fatigue or discomfort rather than clear chest pain. If you suspect a heart-related emergency, such as a possible heart attack, it is very important to act quickly and seek immediate medical help by calling emergency services or going to the nearest hospital without delay, as early treatment can be life-saving. While waiting for help, the person should sit or lie down comfortably and avoid exertion. If prescribed by a doctor earlier, a tablet like Aspirin may be taken to help reduce clotting, unless there is a known allergy or medical reason to avoid it. Do not ignore symptoms or try to wait for them to pass, especially if they last more than a few minutes or keep coming back. Quick action, early diagnosis, and proper treatment can greatly improve outcomes in heart emergencies.
