Objectives:
Cilostazol, a type III phosphodiesterase inhibitor, is an antiplatelet agent with vasodilating properties. Positive inotropic and chronotropic effects are frequently observed with cilostazol, but there are few reports on the influence of cilostazol on left ventricular function. The aim of this study was to assess this effect using tissue Doppler imaging (TDI) and two-dimensional speckle-tracking echocardiography (2D-STE).
Methods:
Thirty-five patients with normal left ventricular ejection fraction were enrolled in the study. Left ventricular cardiac function was assessed by TDI and 2D-STE before and after oral administration of cilostazol. Peak strain was defined using the peak radial strain (PRS), peak circumferential strain (PCS) and peak longitudinal strain (PLS). Time to peak strain was defined based on the times to PRS, PCS, and PLS, as T-PRS, T-PCS, and T-PLS, respectively.
Results:
After cilostazol administration, there were significant decreases in the left ventricular end-diastolic and end-systolic diameters (47.3 ± 5.2 vs. 43.3 ± 4.9 mm, P < 0.0001; 29.3 ± 6.4 vs. 26.0 ± 5.5 mm, P < 0.0001, respectively), and significant increases in the left ventricular ejection fraction (70.6 ± 9.5 vs. 72.7 ± 7.8%, P = 0.0381) and peak systolic annular velocity (7.9 ± 1.7 vs. 9.5 ± 3.1 cm/sec, P < 0.0001). PRS, PCS, and PLS all increased significantly and T-PRS, T-PCS, and T-PLS all decreased significantly after cilostazol administration.
Conclusion:
Positive inotropic and chronotropic effects of cilostazol were found based on assessment by TDI and 2D-STE. We suggest that periodic echocardiographic assessment should be performed before and after oral administration of cilostazol.
