ABSTRACT
Plasma creatinine phosphokinase (CPK) elevation is frequent after heart transplantation. In the present study, we tested the hypothesis that this CPK elevation is related to idiopathic cardiomyopathy as primary cardiac disease. We included 203 patients who survived >1 year after heart transplantation. Plasma CPK was measured every 4 months during a 15.1 ± 7.7-year follow-up. In univariate analysis, CPK elevation was significantly associated with age at transplantation, length of follow-up, treatment with everolimus, and idiopathic cardiomyopathy as primary cardiac disease. In multivariate analysis, idiopathic cardiomyopathy and length of follow-up were the only significant predictors of CPK elevation (p = 0.002 and p = 0.0001, respectively). A subgroup of 19 patients had frequent CPK elevation (>20% of the dosages). All these patients but 1 had an idiopathic cardiomyopathy as primary disease. In 5 of these 19 patients, we identified a syndrome known to affect both cardiac and skeletal muscles. In conclusion, underlying idiopathic cardiomyopathy is a major determinant of plasma CPK elevation after heart transplantation. Our results show that besides well-described syndromes associating skeletal and cardiac muscle disease, idiopathic cardiomyopathy may be associated with subclinical skeletal muscle myopathy.
