[Evaluation of left ventricular function in patients with postinfarction cardiosclerosis by X-ray, angiographic and electrocardiographic findings].

To define the diagnostic value of X-ray criteria for evaluating the cardiac status in patients with postinfarct cardiosclerosis, coronary, ventricular and electrocardiographic findings were compared with X-ray data in patients with two age groups (22-39 and 60-69 years). An attempt was made to substantiate the use of the X-ray technique while examining patients with coronary heart disease (CHD). The comparison of functional and roentgenocardiometric data has revealed that the roentgenocardiometric index, relative cardiac volume, may be used as a noninvasive criterion for evaluating the morphological and functional status of the left ventricle while following up patients with CHD.
