Hey, Hempity. Thanks for the post and that link to the studies. One little clarification, though, courtesy of my husband, who was reading over my shoulder and is a cardiologist. Unless there was another abstract specifically addressing the issue of angina that we couldn't find, this abstract doesn't quite make the leap to say cannabis helps prevent angina (heart-related chest pain). It says that it can reduce infarct size and seems to be important in protecting against myocardial ischemia in rat studies. An infarct is an area of dead tissue that results from blocked or reduced blood flow. Myocardial ischemia is blocked or reduced blood flow. So that may or may not have any effect on angina. He said that to make that link between cannabis and angina, there'd have to be human studies so folks could tell us whether or not they had improvements in chest pain after smoking. So far, we don't actually even know whether or not humans would show this same improvement in ischemia or infarct size that rats do. Maybe soon someone will study that and find out!
