[Echocardiographic detection of wedged emboli in the right heart in patients with pulmonary embolisms].

The authors describe two case-histories of patients with the clinical picture of pulmonary embolism where on echocardiography a mobile formation in the right atrium was detected. In both patients the embolus of peripheral origin wedged in the right atrium was removed by surgery.

[Contralateral asynergy after myocardial infarct].

The purpose of the work was to assess whether during several years of echocardiographic follow-up of patients after myocardial infarction later contralateral asynergy develops (i.e. asynergy of another coronary vessel than that which supplies the area of the infarction) and what are the clinical symptoms associated with its development.

[Are there abnormalities of parathormone, calcium and phosphorus metabolism in hypertrophic cardiomyopathy?].

The importance of calcium and phosphorus metabolism for the development of hypertrophic cardiomyopathies is still obscure. Therefore 52 patients with hypertrophic cardiomyopathy were subjected to detailed cardiological and laboratory examinations. Twenty-five age matched healthy subjects served as controls.

[Myocardial infarct. Results and tactics in reperfusion therapy].

In a group comprising a total of 217 patients with a recent myocardial infarction, who were treated with streptokinase the authors provided evidence that early recanalization of the coronary occlusion occurred after superselective intracoronary administration in 81 and 83% of the patients. After intravenous streptokinase administration they recorded early recanalization in 62%. They found a significant diminution of the infarction focus and improved left ventricular function, as compared with patients treated in the "classical" way by antiarrhythmic drugs, beta-blockers and vasodilatating drugs.

[The importance of the determination of primary bile acids in diseases of the digestive tract].

The authors assessed the concentration of primary bile acids in patients with liver diseases, diseases of the gallbladder and biliary pathways, with affections of the pancreas and in a control group. Primary bile acids and their conjugated derivatives were assessed by radioimmunoanalysis from the patients' serum, using radiodiagnostic sets of Farmos Co. Finland.
