[Changes in hypertrophy and diastolic left ventricular function during hypertension therapy].

The authors examined a group of hitherto not treated patients with primary hypertension and hypertrophy of the left ventricle. By means of echocardiography and isometric loading they investigated the effect of treatment on the left ventricular morphology and function. Despite long-term normalization of casual and loading values of the blood pressure the authors did not observe a significant regression of LV hypertrophy. The authors did not find a relationship between the casual blood pressure and weight of the left ventricle with exception of the diastolic pressure after a load. The indicators of diastolic function did not correlate with the weight of the left ventricle but with changes of the end diastolic volume and blood pressure.

[Ebstein's anomaly (a group of 47 patients)].

In a group of 47 patients with Ebstein's anomaly followed up on a long-term basis the authors describe the natural course of the disease as well as contemporary diagnostic and therapeutic possibilities. The authors draw attention to typical symptoms of Ebstein's anomaly and emphasize the importance of early diagnosis by two-dimensional echocardiographic and Doppler examination and the introduction of individual conservative or surgical treatment.

[Segmental analysis of left ventricular wall mobility].

The authors present their experience with subjective and quantitative evaluation of the mobility of the left ventricular wall of the heart. The combination of computer technique and two-dimensional echocardiography makes it possible to evaluate quantitatively the function of the left ventricule of the heart by the method of segmental analysis of wall mobility. Segmental analysis has proved to be a suitable method for assessing the function of the left ventricle particularly in subjects with threshold or slightly decreased functional values. The authors use the method in studying the functional response of the left ventricle to diagnostic or therapeutic intervention. The method yields important information also on the development of left ventricular function after myocardial infarction in follow-up studies. Subjective assessment is a less demanding approach and when carried out expertly, the extent of muscular damage can satisfactorily be evaluated.

[Stress echocardiography in clinical cardiology].

In their generally designed presentation the authors focus on practical problems concerning indication, different stress modalities and projections, evaluation and interpretation of findings, as well as on technical novelties and their use. Only dynamic exercise echocardiography is being discussed. Currently available knowledge is assessed in the light of the authors' own experience. Problems of evaluation and interpretation are considered to be most intricate. In the authors' opinion, many technical problems which have prevented the routine use of the method in practice will be eliminated by introducing technical novelties such as digitalization of the display with image loop. Other innovations will certainly be used to advantage and render the method less demanding and far more widespread.

[Long-term monitoring of changes in contractility of the left ventricular wall in patients with myocardial infarct].

Using two-dimensional echocardiography, the authors made a one-year investigation of left ventricular function in a group of patients after a first transmural myocardial infarction. They evaluated subjectively and quantitatively changes in the contractility and the development of the diastolic area of the left ventricle. They revealed a certain improvement of the contractility, probably as a result of the development of a collateral circulation and altered structure of the infarction focus associated with dilatation of the left ventricle by the Frank-Starling mechanism.

[Comparison of changes in the mobility of the left ventricular wall with coronarographic findings in patients after myocardial infarct].

The authors examined by echocardiography at rest and after exertion a group of 55 patients after a clinically confirmed first transmural infarction. They compared the echocardiographic findings with coronarographic ones. The finding at rest, as regards impaired mobility of the left ventricular wall, corresponded to the clinical finding and the coronarographic finding. By diagnosis of the extended asynergy of contraction during an isometric load it was not possible to differentiate the functional and organic cause of impaired mobility and thus to assess the extent of the coronary affection. The impaired mobility of the left ventricular wall is associated above all with the state of the blood supply rather than with the finding on the coronary artery.
