Thanks for writing in.
I am a qualified and certified cardiologist. I read your mail with diligence.
On basis of history it seems unlikely that you have had heart attack
. However, one can not exclude problems related to heart like Paroxysmal Nocturnal Dysnea or related to airways Obstructive Nocturnal Apnea
. You need to be seen by a doctor who would thoroughly examine you and if needed shall do one or more of the tests like ECG, Echocardiography
, Chest X-ray, to name some before we can reach a final conclusion. Good Luck.
With best regards.
