Yes, this.
My father had a heart attack the day before his 49th birthday, heavy smoker, recovered without surgery, did the rehab, quit smoking and lived a good active life until cancer got him at the age of 82.
I have been worried about mine since that day and with some serious bouts with acid reflux ( it will create chest pains), my doctor asked if I had ever had a calcium heart scan - I had not, but with my family history he suggested I spend the $100 and go to the basement of St. Josephs for one that day. Best $100 i ever spent for the peace of mind as my results came back at 0-10% calcium build up. The actual words from the nice lady were "you won the genetic lottery"
SO, genetics and lifestyle both play key roles in heart health, but pay attention to the lifestyle as that is the only controllable variable.
