In Japan, methamphetamine accounts for the majority of illicit drug use and dependence is becoming a critical issue. Methamphetamine abuse induces cardiovascular complications, such as cardiomyopathy and heart failure. However, methamphetamine-associated cardiovascular complications are not common in Japan. We report the case of a young patient with hypertensive heart disease associated with habitual methamphetamine abuse. A 37-year-old man was admitted with congestive heart failure. He was a habitual methamphetamine abuser and developed chronic hypertension after he started methamphetamine abuse. His echocardiogram demonstrated left ventricular concentric hypertrophy with diffuse hypokinesis. An endomyocardial biopsy revealed histological evidence of a hypertensive heart. This case shows that habitual methamphetamine use may cause hypertensive heart disease because of chronic hypertension. <Learning objective: Methamphetamine-associated cardiomyopathy and congestive heart failure are uncommon in Japan. However, habitual methamphetamine abuse can be a potential cause of hypertensive heart disease due to chronic hypertension and congestive heart failure associated with hypertrophy.>.
