Had a heart checkup 3 years ago, all well. now i feel i'm having heart attack symptom. is it possible for heart to deteriorate in 3 years?

Yes!: We once had a patient drop by our office having a heart attack on his way home from a normal stress test. Go to your nearest emergency room immediately!

Possible: In you age it is rather unusual to have coronary artery disease. If you have strong family history of heart attack, very abnormal levels of cholesterol and unhealthy life style - it is possible for you to have heart attack.

Yes: Things can change dramatically in 3 years. See a cardiologist & get evaluated asap.
