title: Lack of tacrolimus-induced cardiomyopathy.
abstract: BACKGROUND
  Hypertrophic cardiomyopathy (HCM) has been reported in pediatric transplant patients receiving tacrolimus. It is unclear whether tacrolimus is associated with HCM in adult transplant recipients.
  
  
  OBJECTIVE
  To determine the prevalence of HCM in noncardlac adult transplant patients receiving tacrolimus.
  
  
  METHODS
  A retrospective analysis of nonheart transplant recipients who received tacrolimus at our institution from January 1982 to April 1996 was conducted. Patients with left-ventricular hypertrophy (LVH) defined as a posterior or septal wall thickness > or = 1.3 cm by echocardiography (ECHO) were independently evaluated.
  
  
  RESULTS
  There were 3609 patients who met entry criteria including 2257 liver, 1333 kidney, and 19 other organ transplants. Of the 502 patients who had undergone ECHOs after transplantation, 171 had LVH. The etiology of LVH was categorized as valvular disease (36%), hypertensive disease (29%), ischemic heart disease (17%), or multifactonal (15%). There were six patients in whom, after detailed chart review, no underlying cause of LVH was evident. Five of these patients had HCM, representing an overall prevalence of 0.1% in the entire group of tacrolimus-treated patients, and 1% in patients referred for ECHO.
  
  
  CONCLUSIONS
  The prevalence of HCM in our tacrolimus-treated adult transplant population is similar to that reported in general population studies. These data suggest that tacrolimus is not a risk factor for HCM in adult transplant recipients.
