My father got Heart attack on December 05, 2011 and admitted to Hospital. Prior to that he was perfectly all right no blood pressure, no sugar , no attack or heart problem in past but having his cholesterol on higher side from last one year. Now the Angiography (Left Anterior Descending Artery) conclusion is "Tight ostial stenosis followed by another tight stenosis after first diagonal branch". He has been recommended surgery. I will be thankful for expert opinion .
