They couldn't get a stent through an artery feeding the LF of my heart. But there are minor arteries handling the load. Except when the heart is working harder than the B team can deal with. The choice is a coronary by-pass operation or cardio -rehab .Exercise machines with monitors. 1 hr X 3 days a week. I'm taking dilators and 80mg of a statin.along with 2 others. It generic, so its cheap. The gist of cardio is to keep your pulse rate below 94 beats per min.I decided to get my stumps removed to make way for an upper plate. 5 teeth yanked , all broken. One was infected, a low grade infection that flared and went away when another tooth was pulled.. The oral surgeon got the bad un'. The infection was routed out with a super dremel. I feel like fricken Fred Astaire, I'm so limber. My intent is get tuned up enough to replace about 900 sq feet of roof. Do exercisers use them? are there any favored brands. AAA batts over coins? Thank you in advance
