I just talked to My Mom. My Dad had 90% blockage in the left LAD "Left Anterior Descending coronary artery". They did angioplasty and a stent. He has to stay overnight in the hospital and should be home tomorrow afternoon. That was really a close one. A heart attack caused by this is called The Widowmaker. Widowmaker is the nickname given to a heart attack caused by a blood clot in the left anterior descending artery. It is caused by plaque build up in the artery, and may have virtually no symptoms until the victim falls dead suddenly and unexpectedly. Thank God he found out soon enough. Wish I could see him.

It's been two years since my Dad had angioplasty and a stent for his blockage and he is doing fine. He plays golf every day and works part time.
