So my father underwenr 4×cabg abouy a month ago and they used the following grafts

Lima

Radial artery

Saphenous vein

So the issue is he was put on diltazem ( calcium channel blocker ) as his bp medicine but his pulse remained constantly high even 4 weeks post op so we consulted a total of three cardiologist

Two suggested to change diltazem ( calcium channel blocker) to metoprolol ( beta blocker ) while one said that since " radial artery graft " was used it is prone to spasm it is better to stay on calcium channel blocker despire high HR.

My question is to all those who too had radial artery graft as of what bp medicine they were prescribed and are taking ?
