What are the warning signs of a heart attack?

adminon

  1. Shortness of breath without any particular effort

Is climbing stairs becoming difficult, or are you out of breath after a simple walk? It's not necessarily a sign of poor fitness. Sudden shortness of breath can be linked to an imbalance between oxygen supply and the heart's ability to distribute it throughout the body. This signal is often present in people  with heart failure.

  1. An unexplained feeling of weakness

Sometimes you might feel  completely drained  of energy for no apparent reason. This feeling of weakness, especially if it occurs without prior physical exertion, can be a sign that your heart isn't functioning optimally.  It shouldn't be ignored, especially if other symptoms are present.

  1. Dizziness accompanied by cold sweats

Feeling dizzy or experiencing a sudden, unexplained cold sweat is never harmless. It can indicate poor blood circulation, particularly to the brain.  If in doubt, it's best to consult a doctor.

  1. A feeling like the flu… without fever or virus

Do you have aches and pains all over, a fever, or mild nausea? Some people who have had a heart attack report experiencing these flu-like symptoms in the days leading up to it. If this feeling develops without a real fever or identifiable cause,  it's important to pay attention.
