Dear Sir Thanks for writing to us. I am sorry to hear that you had so much of morbidity at such a young age. Both your concerns are true. There can be a heart attack during the process of angioplasty and a patient may die of the complications of procedure. Overall risk of death is less than 1% while a heart attack may occur in 3-5% of individuals. This is a small but real risk. Your treating cardiologist will explain you all this in detail before doing the procedure. Sincerely Sukhvinder
