My father Is COPD patient and had BP since 15 years he used telmisartan 40 mgOD and the BP is In control usually 140/90 Recently He checkup in KIMS Cardiologist advice 2D echo but the report is normal but last year he took Angiogram of Heart The report is saying 20% block in minor vessel that's not to cause any harmful he took 3 months medication of Atorvastatin and Ecosprin. My doubt is this time the doctor put 3 types of antihypertensive like clonidine 5 mg diltiazem 120 mg and Telmisartan 80 mg + chlorthalidone 12.5 mg This many types of drugs Needed to My Father? Finally Doctor advised Repeat Angiogram of Heart.
