BACKGROUND: Methamphetamine dependence is a major public health problem. This study examined the nature, and extent, of cardiovascular disease amongst cases of methamphetamine-related death in Australia, 2009-2015.
METHODS: Analysis of 894 cases of methamphetamine-related death with full autopsy reports retrieved from the National Coronial Information System.
RESULTS: The mean age was 37.9yrs (range 15-69yrs) and 78.5% were male. A quarter (26.3%) of cases had enlarged hearts and left ventricular hypertrophy was diagnosed in 18.9%. Severe coronary artery disease was present in 19.0%, the left coronary artery being the vessel most frequently stenosed (16.6%). Replacement fibrosis (evidence of earlier ischaemic events) in the heart muscle was observed in 19.8% of cases, and cardiomyopathy was diagnosed in 5.5%. Histological evidence of hypertension was observed in 32.7% of cases. With the exception of cardiomyopathy, equally common amongst both sexes, cardiovascular disease was more common amongst males, and those aged >35yrs. Clinically significant levels of cardiovascular disease were also observed amongst cases where the cause of death was not attributed to cardiovascular disease: cardiomegaly (19.3%), left ventricular hypertrophy (14.6%), severe coronary artery disease (9.4%), replacement fibrosis (14.4%), cardiomyopathy (3.3%).
CONCLUSIONS: Cardiovascular disease was highly prevalent, despite the relatively young age of cases. With methamphetamine use increasing rapidly in major regions, cardiovascular disease and cardiovascular-related death will likely increase amongst methamphetamine users.
