heart attack
"I am a health care worker and  inherited the risks of heart disease and diabetes. Worked for years in a high stress University teaching hospital. Had vague symptoms, knew what to do and didnot delay getting to an ER. Called a friend/cardiologist - yes,had a heart attack without muscle injury(thank heavens!)Had triple bypass. Followed Doctors order to the "T". Recently started on lisinopril and have had improved blood pressure and heart rate control. Overall feel 90% better."
