What will be the reason for heart attack in young age?

We need to clarify something from the outset. Most deaths of young people that are cardiac in origin, are not really heart attacks (correct name: myocardial infarction) In myocardial infarction, plaques appear in the coronary arteries of a person, and a clot results in the prevention of oxygenated blood reaching a section of the heart, and cell death occurs.

This is generally a phenomenon of older people, although there is more coronary artery disease in the young than there once was.

When a person in their twenties dies suddenly from a cardiac issue, it is often an arrhythmic disorder, or one of the disorders which episodically produces an abnormal heart rhythm which may be incompatible with life. Some of these disorders are:

1. Long QT syndrome

2. Brugada Syndrome

3. Wolff-Parkinson White Syndrome

4. Calcium Channelopathies

5. Viral cardiomyopathies

6. Bacterial cardiomyopathies etc.

7. Supraventricular tachycardias

8. Endocrine disorders which impact

fluid and electrolyte imbalances.

Since these disorders run in families, the family members of those who passed suddenly as young people due to supposed cardiac disorders (some with and some without autopsy documentation), should be followed by a cardiologist. An EKG and echocardiogram and some basic labwork can go a long way to ruling out this being an issue for family members.

Most of the above disorders can be treated, in fact some, rather

easily. However, one has to know that this is a problem first.

Best wishes.

Birth defect in the heart could be one cause as could a drug overdose.
