Statin use is known to be associated with myopathy, muscle weakness and rhabdomyolysis, a breakdown of muscle fibers resulting in the release of muscle fiber contents into the bloodstream. For the study, myocardial function was evaluated in 28 patients.

Abstract:
OBJECTIVES: The purpose of this study was to evaluate the effects of statin therapy on myocardial function as measured with echocardiography with tissue Doppler imaging (TDI) and strain imaging (SI) independent of its lipid-lowering effect. BACKGROUND: Statin use is known to improve outcomes in the primary and secondary prevention of ischemic heart disease, but their use is also associated with myopathy, muscle weakness and in rare cases, rhabdomyolysis. We sought to evaluate whether TDI and SI is able to identify changes in myocardial function associated with statin use. METHODS: Myocardial function was evaluated in 28 patients via echocardiography with TDI and SI. We identified 12 patients (5 females) without overt cardiovascular disease (including hypertension, smoking, and diabetes) that were on statin therapy and compared their echocardiographic findings with 16 (12 females) age, sex, and cholesterol-profile-matched controls. Tissue Doppler imaging parameters of diastolic (E(')/A(') and E/E(')) and systolic (S') function were measured. Regional systolic function was obtained by SI in 4-chamber, 2-chamber, long axis, and average global views. RESULTS: There was no significant difference in myocardial function as measured by Doppler and minor differences as measured via TDI among the 2 groups. There was significantly better function noted with SI in the control group vs the statin group in the 4-chamber (-19.05% +/- 2.45% vs -16.47% +/- 2.37% P = 0.009), 2-chamber (-20.30% +/- 2.66% vs -17.45% +/- 4.29% P = 0.03), long axis (-17.63% +/- 3.79% vs -13.83% +/- 3.74% P = 0.01), and average global (-19.0% +/- 2.07% vs -15.91% +/- 2.81% P = 0.004) views. CONCLUSION: Statin therapy is associated with decreased myocardial function as evaluated with SI.
