[Quantitative and qualitative findings in endomyocardial biopsies from patients with and without hypertension].

Histological and morphometric investigations were made of left-ventricular endomyocardial bioptates which had been obtained from 19 male patients with so-called latent cardiomyopathy as well as from 21 patients with positively verified hypertension and with angiographically excluded coronary artery sclerosis. The patients were additionally divided in two cohorts according to the weight of the left ventricle below and above 170 g. Inflammatory and ischaemic conditions were, above all, histologically recorded from the first group, while microangiopathy was more frequent in the second.

[Semi-invasive measurement of pulmonary pressure as a method of evaluating cardiac function in hypertension and ischemic heart disease. Experience at Charité Hospital for more than 20 years].

Since 1969, microcatheterization (floating catheterization) of the pulmonary artery has systematically been used at the Hospital Charité in Berlin for measuring (indirectly) the left ventricular filling pressure. That seemed especially be justified in patients in whom conventional catheterization was not needed. Noninvasive techniques had not been available.
