Hello, madame. Thank your for your question and welcome to HCM. I understand your concern.
I would like to explain to you that some of the drug classes that are used to lower the blood pressure, such as most beta-blockers and calcium channel blockers (verapamil and
diltiazem) also lower the
heart rate. If I was treating your husband, I would definitively not combine a beta-blocker with verapamil as this combination in counterindicated and very dangerous. In some cases, it can cause the heart to stop. Therefore, I recommend that you should immediately consult your curing cardiologist to take one of these classes off the blood pressure-lowering strategy. After all, there are a lot of other drugs that can be used in this setting, if not counterindicated by any co-existing kidney disease. Angiotensinogen converting enzyme inhibitor (ACE-I: captopril, enalapril, ramipril) drugs,
angiotensin receptor blocker (ARB: losartan,
olmesartan, eprosartan) drugs or diuretic (hydrochlorthiazid,
furosemide) drugs, can be added to his regimen. But, I strongly recommend that either the beta-blocker or verapamil should be stopped, and then monitor the heart rate.
I hope I was helpful. Best regards.
