[|Human|] I am 53 years old and last month I met a heart attack and after angiography, it is diagnosed that my three arteries are block and doctor advise me bypass operation, my problem is that I am also a patient of erectile dysfunction and my question is that can I use Viagra in this condition?
[|AI|]  Hello and thanks for writing. I can understand your concern and would try to help you in the best possible way. Using sildenafil with triple vessel disease is not advisable as it may lead to sudden decrease in blood pressures which may injure an already compromised heart like yours having three vessel disease.Also, if you are taking other medications like nitrates or antihypertensives then sildenafil is absolutely contraindicated. There are other treatments for ED other than sildenafil and I advise that you consult your physician and discuss with him regarding the choices. You may discuss with him the best choice suitable for you considering your condition. I would also suggest that you remain in follow up with your cardiologist for treatment of your coronary artery disease and take medications as prescribed by him.
