[Pulmonary circulation in patients with different types of "hypertensive heart"]

The comparison of clinical and instrumental findings of the state of pulmonary hemodynamics with respect to the type of "hypertensive heart" as determined by ultrasonic location of heart chambers, suggested that, in the absence of left-ventricular hypertrophy or in the presence of concentric myocardial hypertrophy combined with hyperfunction of this heart chamber and normal left ventricular size, increased diastolic pressure in pulmonary artery does not reflect left ventricular decompensation; rather, it is a consequence of increased vascular resistance in the pulmonary arterial system irrespective of its pathogenesis.
