Marijuana Use Before Acute Myocardial Infarction May Give Survival Edge in Hospital
by Deborah Brauser at Medscape
"... After adjustment for age, race, and known cardiac risk factors, there
was no significant association between marijuana use beforehand and the
composite outcome, which included death, cardiac arrest, shock,
mechanical ventilation, or intra-aortic balloon pump (IABP) placement,
after patients experienced an MI.
However, the adjusted odds ratio
(OR) for in-hospital mortality was 0.83 for the marijuana group vs
those who did not use the substance (95% CI 0.7–1.0, P=0.045). And there were significantly lower risks for IABP placement (OR 0.80, P=0.03) and shock (OR 0.74, P=0.001). ..."
"... Lead author, medical student Cecelia P Johnson-Sasso (University of
Colorado, Denver), noted that the data aren't saying that marijuana is
causing events, and they don't yet know the mechanism behind "what
appears to be prevention from death ...."
