#AskDrKK: Can the risk of heart attack after sexual act be minimized?

#DrKKAnswers:
a. The triggers to acute heart attack are increase in heart rate, blood pressure, and myocardial oxygen demand, as well as increased platelet agreeability and coagulation in combination with a vulnerable coronary plaque [1].
b. Drugs that reduce heart rate or blood pressure or inhibit platelet aggregation reduces the risk of triggers of heart attack.
c. Beta blockers minimize or eliminate angina heart pain during sexual act.
d. The Determinants of Myocardial Infarction Onset Study showed that beta blockers reduced the risk of MI following anger [2] but not sexual act [3].
e. Aspirin lowers the risk of heart attack following anger [3] and the morning waking hours [4].
