[Clinical, hemodynamic and cineangiocardiolographic findings in congestive cardiomyopathy].

Sixteen patients affected by congestive cardiomyopathy were studied by means of right and left cardiac catheterization and cineangiocardiography. Cardiac output and mean pulmonary circulation time were determined by the radiocardiographic method. Left ventriculograms were obtained in all the patients in the 45 degrees RAO projection; the left ventricular end diastolic and end systolic volumes were calculated both by the area-length and by the slice method. Among the several hemodynamic data (stroke index, mean pulmonary circulation time, left ventricular end diastolic pressure, left ventricular volumes and ejection fraction) the most early impaired and therefore usefull for an early diagnosis, were: the left ventricular end-systolic volume, the left ventricular end-diastolic volume and the left ventricular ejection fraction.
