We aimed to examine the prevalence of documented cannabis use and its association with survival among patients with HF using the Optum Clinoformatics dataset, large, national informatics dataset. We demonstrated low period prevalence of cannabis use among patients with heart failure and there was no statistically significant difference ( p = 0.76) in all-cause mortality between individuals who use cannabis versus non-users.
Ilonze et al. (Sun,) studied this question.
