Abstract

Objective: To investigate the variation of left ventricular diastolic function during thoracic radiation treatment using Doppler echocardiography. Methods: The study group consisted of 36 patients with thoracic radiotherapy. The patients were examined twice, the first examination: 1~3 days before the radiation treatment; the second examination: the day of radiation treatment was finished. Doppler echocardiographic examinations were performed by measuring the ratio of two peaks of mitral inflow Doppler velocity and mitral annular diastolic velocity profile(E/A, e/a). Results: E/A and e/a between two examinations were significantly different(E/A: 0.77±0.19 vs 0.69±0.13, e/a: 0.82±0.31 vs 0.75±0.19, both P<0.05). Conclusion: Left ventricular diastolic function was damaged during thoracic radiation treatment, which can be diagnosed by Doppler echocardiography in time.
