Abstract | OBJECTIVE: METHODS: We performed a retrospective cohort study, and reviewed medical records of patients with METHrEF, METHpEF and heart failure controls without methamphetamine use. Echocardiographic variables were recorded for up to 12 months, with clinical follow-up extending to 24 months. RESULTS: Among METHrEF patients (n=28, mean age 51±9 years, 82.1% male), cessation was associated with improvement in EF (+10.6±13.1%, p=0.009) and fewer heart failure admissions per year compared with continued use (median 0.0, IQR 0.0-1.0 vs median 2.0, IQR 1.0-3.0, p=0.039). METHpEF patients (n=28, mean age 50±8 years, 60.7% male) had higher baseline right ventricular systolic pressure (median 53.44, IQR 43.70-84.00 vs median 36.64, IQR 29.44-45.95, p=0.011), and lower lateral E/E' ratio (8.1±3.6 vs 11.2±4., p<0.01) compared with controls (n=32). Significant improvements in echocardiographic parameters and clinical outcomes were not observed following cessation in this group. CONCLUSIONS:
