I read your question and I understand your concern. Those values are very high, and especially in someone who has suffered a heart attack strict monitoring and treatment is needed. There are several different classes of drugs to treat high blood pressure, often treatment with more than one drug is not enough. Since one doesn t seem to be enough in your case, you should discuss with your doctor the possibility of adding another drug like a beta-blocker (bisoprolol, metoprolol etc), calcium-channel blocker (amlodipin, nitrendipin etc) or diuretic (thiazides etc). There are others as well, I mentioned the most used ones, so we have many guns in our arsenal, it s a question of gradually finding the most appropriate regimen for you, that s why regular check-ups are needed especially in this initial phase. I hope to have been of help.
