Doppler echocardiographic assessment of left ventricular diastolic function in patients with primary lung cancer treated with doxorubicin.
Eighteen patients were examined by Doppler echocardiography before and after treatment with doxorubicin (DXR). Early left ventricular filling rate decreased from 66 +/- 15 to 51 +/- 10 cm/sec whereas late filling rate increased from 48 +/- 12 to 61 +/- 9 cm/sec (p less than 0.05) with inversion of the E/A ratio suggesting an impairment of left ventricular diastolic function; conversely no significant changes were found in systolic function indexes. These results suggest that follow-up of patients treated with DXR must include left ventricular diastolic function studies. Doppler echocardiography can be successfully used to detect the presence of diastolic abnormalities.
