massive heart attacks

first of all im not sure about the topic. im 13. secong of all i have a theory about massive heart attacks.  i kno wat they are and wat they do. they kill. all of my grandpaws family died of massive heart attacks. and i dont want that to happen to me. well i u kno how if u have a heart attack, thta means that one of your arteries ahve ben bolcked and blood cannot pump to your heart? well i believe that if the arteries that pump blood to your body get clogged up, then your blood starts to build up in your heart and eventually it gets to be too much and your heart explodes. killing you and your family at the same time. and your friends. so be smart and eat, sleep and...do something else right. and you wont be in the kind of pain my family went through.

Not too bad of a theory........but unfortunately, the heart doesn't quite work that way. The coronary arteries are OUTSIDE the heart; they are on top of the heart muscle, not inside of the heart. When the arteries get clogged, they can not deliver blood to the heart muscle; that is what a heart attack is and that is how your relitives died. Their hearts did not explode; although that can happen if the heart wall is thinned out too much. That is actually how my father died.

And not all heart attacks kill. My Dad had 4 heart attacks in his lifetime. They did a lot of damage to his heart (muscle tissue died from the lack of blood flow) but he continued on. Finally died from lung cancer (thank you cigarettes, but that's another story).

your dad was a brave man to keep going and you too for supporting him.  A test yesterday 'suggests' I have  CAD in thrre arteries and face  the alternatives of mediation, more catherters  or finally bypass. I'd be grateful if you would say what route your father took.
