ABSTRACT
We analyzed 80 patients with lung resections due to lung carcinoma operated at the Clinic for Thoracic Surgery. We performed lobectomy or bilobectomy in all cases, the patients were between 50 and 70 years old and the preoperative preparing was the same. The patients were divided in 2 groups; group A -- the patients with anamnesis for myocardial infarction, arrhythmia, pulmonary hypertension or restrictive respiratory disease and group B -- patients without such a history. Echo Doppler cardiography was performed in all cases to measure the main parameters that present the heart-lung hamodynamics. We found some changes even in group B (increased RVEDV, decreased EF, increased pulmonary systolic pressure) which can be a reason for cardiac complications after this type of surgery. The echo-Doppler cardiography is a sensitive and non-invasive method to obtain all valid parameters to present heart-lung haemodynamics.
