The evaluation of the degree of change in left ventricular systolic and diastolic functions during radiation therapy for lung cancer

In patients with lung cancer, the condition of left ventricular systolic and diastolic functions has been evaluated with echocardiography during radiation therapy for lung cancer. Thirty-nine patients were examined using an ultrasound device ACUSON CV-70. Systolic and diastolic functions were evaluated prior to radiation therapy and at doses of 20, 40, 60 Gy. At a dose of 20 Gy, first signs of the left ventricular functional disturbance were noted. With increasing the total tumor dose negative changes in left ventricular systolic and diastolic functions were progressing.
