I have a heart condition called Mitral valve prolapse (MVP). My heart specialist says that it is a mild-moderate regurgitation in the valve and that where it is at, I won't have to get surgery. But if it progresses, then later on in life, I might have to. Now I know marijuana can be bad for people with heart disease, but think those are talking about people who can't have high heartrate or exercise. But with my case, the doctor actually encourages me to excecise and get my heartrate elevated to keep it strong. I cannot lift weights though, because that puts a different strain on the heart. And he also says it's good to keep my blood pressure low, because high blood pressure constricts the vessels or w.e. He also suggested a medication called ACE inhibitors. They lower blood pressure by expanding the blood vessels, therefore taking strain off the heart. But I refused for now. Would marijuana act like ACE inhibitors (relaxng/widening blood vessels), or does it cause blood vessels to constrict? Now I don't know when I can get another appointment with him so I am asking for any information anyone might have on weather weed would be beneficial, bad, or neutral for my condition. (I can have increased heartrate, but not high blood pressure or lift weights) Any info or links would be nice.
