This is a good example of survivorship bias. You're fixated on the few heart attacks you do know and overlooking the vast troves of people who never developed issues once treated.
No, the survivorship bias is having high blood pressure and being fine. It greatly increases your risk of heart attack, stroke, and heart failure. Hypertension is dangerous in the long-term. Most smokers don't die of lung cancer - they die of hypertension.
Every heart attack story I know of off the top of my head involves a man who didn’t want to take his blood pressure meds.
