[Application of non-invasive methods to assessment of left ventricular function in cardiomyopathy (author's transl)].

Left ventricular function in cardiomyopathy was studied by non-invasive methods. Various indices of left ventricular function were measured in patients with cardiomyopathy by mechanocardiography and echocardiography and were compared with indices in normal subjects and the following conclusions were obtained. 1) Patients with Congestive cardiomyopathy had high PEP/LVET, low mVcf, low EF, and low mPWV, suggesting depressed cardiac function. 2) Patients with Hypertrophic obstructive cardiomyopathy had characteristic findings, such as low DDR, high IVST/PWT, and SAM. 3) Patients with Hypertrophic non-obstructive cardiomyopathy had no characteristic changes in indices, however in some of the findings transition to Hypertrophic obstructive cardiomyopathy was suggested.
