heart attacK/V-FIB

my dad was 50 ,he had a mild heart attack in the month of may we were referred to a cardiologist who did angiogram and they found 2 valves blocked and 1 valve was 80% blocked and the other one is 30% blcoked  he mentioned valve which is 80% blocked is CA and needs attention and he mentioned other one which is
30% will be fine by taking medicine...he advised angioplasty for the valve thats 80% blocked so as suggested we did a angioplasty and my dad was fine for 2 months .on one unfortunate day .my dad went to office came back had his dinner and said he had acidity feeling and he took dygene and within minutes he had vomit sensation and before we could get ambulance he passed away and this happened in juz 5mins.just wanted to check sir is it because stunt failed or ???

I'm sorry to hear that you have lost your father. Chances are much greater that your fater died from a cardiac arrhythmia where the bottom chambers (ventricles) started beating in the wrong way (V-tachycardia/V-Flutter and Fibrillation) The stents probably had nothing to do with what happened.
