He had all the symptoms of a heart attack. My dad had the same symptoms at 50. We took him to the ER even though he didn't want to go. Diagnosis: Myocardial Infarction. He was admitted to the hospital. He lived.

Last September, my 39 year old cousin wasn't feeling well at work (he owned a business). Went home. His father-in-law was supposed to meet him in his apartment lobby a few hours later. When my cousin didn't show up, his father-in-law asked if they would let him into the apartment. They did. My 39 year old cousin was slumped over his desk. Deceased. They diagnosed it as a heart attack. He smoked, was stressed over his business, and had a bad habit of drinking energy drinks.
