ABSTRACT
BACKGROUND: Whereas the efficacy of statins after heart transplantation (HT) in controlled study settings has been clearly demonstrated, more extensive data are required on the safety and effectiveness of long-term treatment in routine clinical practice. METHODS: We analyzed the risks and benefits in clinical practice of treatment with statins in all patients who survived HT for at least a month from December 1985 through 2001. RESULTS: During a mean follow-up of 4.8+/-3.8 years, 186 patients were treated with statins (for a median duration [25th to 75th percentile] of 29 [12 to 54] months), while 48 received dietary therapy alone. Patients treated with statins (pravastatin, 48%; atorvastatin, 37%; simvastatin, 14%) presented linearized rates of rhabdomyolisis, myositis, and significant transaminase elevation of 0.37%, 0.74%, and 0.37% per year of treatment, respectively (no fatal event occurred). Low-density lipoprotein decreased after statins by 19% (P<.001). At multivariate analysis, treatment with statins was independently associated with reduced risk of cardiac allograft vasculopathy and overall mortality (P<.001). CONCLUSIONS: Our data provide necessary confirmation of the safety and effectiveness in routine clinical practice of appropriately monitored long-term administration of statins (particularly atorvastatin, pravastatin, and simvastatin) in the chronic post-HT phase. Strict follow-up is needed for HT recipients receiving high doses of statins with/without other medications potentially exacerbating the risk of adverse effects.
