kmart--I found it especially helpful to write down questions as they popped into my mind over several weeks, rather than waiting until just before the visit. That way, I didn't miss anything I wanted to ask. For me, having the written questions ( a copy for me, a copy for the cardiologist)made the difference, because I didn't have any questions unanswered after my visit. I also researched particular aspects of my condition so that I could ask informed questions. For example, "What role does collateral circulation play in coronary artery blockage"?
