Hello, 49-year-old male here. Approximately 2 and a half years ago I experienced a "mild" heart attack which led to angioplasty to the second diagonal branch of the left coronary artery with the placement of a des resolute integrity 2.25x18x1 mm. Since then I've been taking daily clopidogrel 75 mg, rosuvastatin 10 mg, metoprolol tartrate 25 mg and acetylsalicylic acid 100 mg and have never experienced any discomfort whatsoever. Never in my life I had (or have) problems with high blood pressure or high blood sugar, my problems were cholesterol related, which of course now is way lower than the limit due to diet and medication. But I am experiencing problems in obtaining/sustaining an erection. I wanted to ask, is it safe for me to take viagra etc. Furthermore is there any point in continuing taking metoprolol since I never ever had high blood pressure issues? Many thanks in advance.
