“Heart attack?”

Without knowing anything more about your medical history, it is impossible to be 100% certain. If you dont smoke and are premenopausal and have not suffered from uncontrolled blood pressure for years, a very bad lipid profile or diabetes, or a family history of premature coronary disease, it is very unlikely. To be sure, you would have to go to an emergency room or urgent care center and have an EKG and blood test.

This could certainly be a heart attack. 50% of middle-age males have some degree of athero seclerosis (cholesterol plaque in the coronary arteries, hardening of the arteries, cholesterol deposits in the coronary arteries, are some of the lay terms that are used to describe this condition). The symptoms you described are compatible with a heart attack. If I had you on the phone in my office I will tell you to call 911 and get yourself to an emergency room immediately. Of course, it could be a number of other things, fairly numerous to enumerate, so I will not do that. Basically you need a thorough and complete evaluation immediately. And the emergency room life-threatening conditions will be ruled out included in a heart attack, but there are other serious conditions that could cause you about symptoms. And no life or any conditions are discovered, a tentative diagnosis would be made, perhaps tentative treatments would be started, and a more deliberate and complete evaluation would be carried out, either I've been admitted overnight to an oxidation unit, being admitted to the hospital for more prone stay, or just as likely, be sent home.
