I may contribute a couple of ideas @contender1, but have had no experience with coronary surgery or its related problems. I can address swollen ankles and calves after overcoming them a few months ago; the problem was a calcium channel blocker with a standard side-effect of ankle swelling. My internist and I agreed to replace that medication with a beta blocker, and my ankles are fine now. But that's not the end of it -- I renewed treatment by my nephrologist to find out whether my kidneys are complicit. I also am in a-fib and asked for a second opinion from a distinguished cardiologist to see whether my heart is not performing well enough. It will be a couple of weeks before we finish revising my treatment plan, but with those two doctors homing in on it, I'm confident of reaching stability with proper medication to control my BP.
