title: [Dynamics of echocardiographic index in aquanauts during the period of long-term effects of deep diving (to 500 m)].
abstract: The authors presented the echocardiography and doppler sonography of aquanauts during the period of long-term effects of deep diving (to 500 m). According to the analysis of the given data the following was revealed: imperceptible atrium distensibility, left ventricular concentric remodeling without myocardial hypertrophy, saving of general and regional myocardial contractile function, left ventricular diastolic dysfunction grade 1, intact right ventricle, orthoarteriotony in pulmonary artery, change of size and distensibility of the aortic root. The authors came to conclusion that there are 2 different process in the structural ventricular remodeling during the period of long-term effects of deep diving--envolving myocardial consolidation and heart chamber dilation. These two processes is connected with temporary factor atypical for natural age dynamic. The aortic root has a atherosclerotic change and distensibility. There is no further dynamic distensibility. The abovementioned changes in heart and aorta can progress in aquanauts, which have too many dives. Patients in the study group haven't dived over the years, but nevertheless have the abovementioned changes.
