Chest Discomfort: This is the most common symptom. It may feel like pressure, tightness, fullness, or pain in the center or left side of the chest that lasts for a few minutes or comes and goes.

Shortness of Breath: Feeling breathless or having difficulty catching your breath, even with minimal physical exertion, can be a sign of reduced blood flow to the heart.
Fatigue: Unexplained fatigue or feeling unusually tired, especially if it’s accompanied by other symptoms like chest discomfort or shortness of breath, could indicate a heart problem.
Weakness: Sudden weakness or lightheadedness, particularly if it’s severe or persistent, may be a warning sign of impending heart trouble.
Dizziness or Nausea: Feeling dizzy or nauseous, especially when combined with other symptoms, could indicate reduced blood flow to the heart.

Sweating: Experiencing cold sweats, especially without any obvious reason such as physical activity or hot weather, might be a warning sign of a heart issue.
It’s important to emphasize that these symptoms can vary widely from person to person, and not everyone will experience them before a heart attack. Additionally, some people may not have any warning signs at all. If you experience any of these symptoms, especially if they’re severe or persistent, seek medical attention immediately. Early detection and treatment can significantly improve the outcome of a heart attack.
