THC protects heart cells in the case of lowered oxygen supply

Israelian researchers at the Bar-Ilan University in Ramat-Gan demonstrated that THC protects heart cells (cardiomyocytes) against the damage caused by hypoxia (reduced oxygen concentration in the blood) in experimental studies. Pre-treatment of cultures of cardiomyocytes with THC for 24 hours prevented leakage of LDH induced by hypoxia. Leakage of LDH (lactate dehydrogenase) from cells is a sign of cell damage.

This protective effects of THC was mediated by the CB2 receptor. CB2 receptor activation by THC induced the production of nitric oxide (NO). Nitric oxide signals the smooth muscles of blood vessels to relax, thus dilating the artery and increasing blood flow. This underlies the action of nitroglycerin and other drugs used in the treatment of heart disease, since these compounds are converted to nitric oxide in the body.

Researchers noted that THC also "probably pre-trains the cardiomyocytes to hypoxic conditions." They concluded that their research "demonstrates that THC has beneficial effects on cardiac cells and supports the consideration of marijuana for specific medical uses."
