[Significance of laboratory diagnostic study parameters of the hepatobiliary system in the evaluation of cardiovascular diseases--results of cross sectional and longitudinal studies in patients with suspicious cardiovascular findings in an epidemiologic follow-up study].

With the help of an approx. 280 000 inhabitants check of x-ray-morphological suspects of a heart disease the laboratory parameters thymol turbidity test, zinc-sulphate turbidity test, total protein, serum protein electrophoresis and the enzymes "ASAT" and "ALAT" in longitudinal section and cross-section were examined in an intervention study during 5 years. All these parameters show standard values on the average, but compared to a healthy reference they showed significant differences, which relations to heart and vessel diseases could be deduced from. This referred especially to age-inverse behaviour of the transaminases only concerning male test persons. The examination of the longitudinal section confirmed exactly the results of the cross-section analysis. On the one hand it underlines the results got from the cross-section and in the second place it contributes to the efficient diagnostics by learning undone a repetition of these laboratory examinations during the period of 5 years with such a defined population. The relations of the particularities mentioned obviously refer to subclinical fields. Effects of therapy do not reflect in the laboratory findings.

[Cardiovascular x-ray findings, changes of the thoracic aorta, electrocardiographic and clinical parameters in hypertension. 1. Cardiovascular x-ray findings in hypertension].

We examined 142 hypertensive patients of special consulting hours for hypertension. In a subdivision into 3 degrees of severity of hypertension and into the age groups less than or equal to 50 years and greater than 50 years X-ray findings on the heart and on the large vessels near the heart were made. Patients with blood pressure values RRs greater than or equal to 160 Torr and RRd greater than or equal to 95 Torr had these findings in 78%. 56% of the test persons with a heart affected in the left ventricle (R1) were found and 23% of the test persons with left-prevailing heart affected on the two sides (R3). The positive correlation between age of the patients with hypertension, duration of hypertension and frequency of the heart deformation in the sense of the left-ventricularly affected heart and the left-prevailing heart affected on the two sides could statistically be ascertained. 62% of the patients less than or equal to 50 years and 89% of the patients greater than 50 years had these findings. In a duration of hypertension less than or equal to 5 years 64% had these findings, in a duration of hypertension greater than 5 years 64%. The total number of findings increases with the degree of severity of hypertension. In test persons with degree II of severity of hypertension (RRs 160-200 Torr, RRd greater than or equal to 95 Torr) 73% had these findings, in test persons with degree III (RRs greater than Torr, RRd greater than or equal to Torr) 86%. The relation of the heart deformation in the sense of the left-prevailing heart affected on the two sides between degree II and III of the severity of hypertension was contradictory. In hypertension II and duration of hypertension greater than 5 years the percentage of the test persons with left-prevailing heart affected on the two sides was 42%, in hypertension III and duration of hypertension greater than 5 years 19%.
