Heart Attack Warning Signs: Heart attacks are commonly believed to attack without warning however medically there are small signs of distress that the body can start to give even as long as 24 to 48 hours before there is a large cardiac occurrence. The early signs of these diseases may be life-saving because fast medical intervention can save a lot of the heart and save lives.
According to Dr. Ashish Agarwal, Director & Unit Head (Unit-1), Cardiology, Aakash Healthcare, here are some of the early warning signs of a heart attack:
Constant chest pain is one of the first indicators. It can be pressure, heaviness, tightness or even pinching not sharp pain. In contrast to the most heart attack pain, initial pain can be intermittent, as people tend to attribute it to acidity or muscle tension.
Breathlessness, which comes out of the blue, in either rest or light activity, may be an indicator that the heart is not pumping effectively. This symptom can be observed either without the presence of pain in the chest and particularly, it cannot be neglected.
The frequent early symptom reported is extreme tiredness of an unidentified cause especially in the 48 hours prior to a heart attack. Even easier things can be tiring and the body can be abnormally heavy or fatigued although one has enough sleep.
The days before a heart attack, many people feel restless, have a poor sleep or get sudden anxiety. This can be attributed to weakened blood flow and alterations of stress hormones since the heart gets impaired.
The pain can extend to the left arm, shoulder, neck, jaw, or upper back. Others complain of the vague aches or the feeling of pressure instead of pain which can be easily ignored.
It may cause nausea, indigestion, bloating or burning pains in the upper abdomen, especially at the initial stages. The symptoms are usually confused with those of stomach problems.
The presence of any of these symptoms particularly when new, persistent or progressive should be evaluated urgently. Delay in classic chest pain may be risky.
A heart attack is usually preceded by warning signs on the body. Paying attention to such signs and taking necessary care on time can be a matter of life and death.
