[Diabetic angiopathy--retrospect and prospect].

Max Bürger intensively dealt with the problems of angiopathia diabetica which determines the prognosis of the diabetic. His successful action in diabetogenic gangrene must from the modern point of view possibly supplemented by methods opening the vascular lumenor by haemorheological therapy. In contrast to this many questions of the prophylaxis and early therapy of arteriosclerosis in diabetes mellitus still await their only interdisciplinary possible clarification. In practice hopes are connected with the new possibilities of the management of metabolism in diabetes type I and the improvement of the patient's compliance.

[Myocardial scintigraphy using technetium-99m-diphosphate in combination with selective coronary perfusion scintigraphy and coronary angiography].

The findings of the scintigraphy of the myocardium with Technetium-99m-diphosphonate (Tc-99m-DP) of 45 patients with nearly exclusively ischaemic heart disease were compared with those of the selective coronary angiography and those of the selective coronary perfusion scintigraphy. 12 patients exhibited an enlargement of the activity in the myocardium (positive scintigramme). These cases were particularly described in this paper. The levocardiogramme proved disturbances of the motility of the walls in 6 patients. In 5 patients a positive scintigramme of the myocardium was registered. Therefore, the scintigraphy of the myocardium with Tc-99m-DP is regarded as a supplementing, non-invasive method for the diagnosis of more pronounced disturbances of the motility of the heart wall. Furthermore, positive scintigrammes of the myocardium were registered in angina pectoris, condition after aorto-coronary bypass-operation, cardiomyopathy and myocarditis. Since the scintigraphy of the myocardium with Tc-99m-DP is a sensitive method for the poor of cell lesions of the myocardium, it allows a judgment of the floridity of the myocardial process. From this among other results that the scintigraphy of the myocardium may be a help for the indication to the aorto-coronary bypass operation. Clear relations between the scintigraphy of the myocardium, the number of the coronary-sclerotically changed heart vessels and the development of stenosation are not to be established. An immediate connection between the size of the disturbance of the perfusion and the results of the scintigraphy of the myocardium is also not to be recognized.

[Abnormal myocardial blood flow distribution with a normal coronarogram in angina pectoris and after myocardial infarction].

It is reported on the selective coronary perfusion scintigraphy in 47 patients with angina pectoris and condition after myocardial infarction, which was performed simultaneously with the coronary angiography. For the paper were interesting the cases with normal coronarogram, but pathological perfusion scintigram. 3 of 25 patients with condition of infarction showed coronarographically inconspicuous vessels. In all cases the perfusion scintigram shows disturbances of regional perfusion, which corresponded with the electrocardiographic localisation of the infarction. In 3 of 22 patients with angina pectoris with normal coronarogram in the scintigram regional changes of the terminal vascular system were established. In 2 cases simultaneously a disturbance of rhythm and stimulus conduction was present, which showed a conspicuous correlation to the perfusion lesions in the septum. In the small intramural vessels haemodynamically effective changes take place which are below the coronarogram. Therefore, the only coronarography is not enough to confirm or to refuse a genuine angina pectoris or an infarction. The selecitve coronary perfusion scintigraphy gives the possibility to prove disturbances of the distribution of regional blood supply without a greater additional load of the patient as to coronary angiography. However, it cannot give evidence on the genesis of disturbances in the terminal vascular system in the normal coronarogram

[Clinico-diagnostic criteria for the evaluation of social aspects in acquired heart valve diseases].

In spite of the retrogression of the acute rheumatic fever the acquired valvular defects still play an essential role for the morbidity and mortality above all for the younger and middle decenniums of life. In the preliminary diagnostics it is the task of the family doctor to diagnose the valvular defect, to differentiate it from non-organic findings and to estimate its degree of severity. The diagnosis of a carditis renders special difficulties, particularly in its chronic recurrent form. Certain situations of life do not demand only an actual analysis of the findings, but also an individual prognostic estimation. For the choice of profession, the ability for military service and driving a car general references and regularities must be taken into consideration. The indication to operation of the valvular defect is generally given in degree of severity and with restriction also in stage IV. A mitral stenosis is operated already in stage II, when stronger complaints and haemodynamic changes are present. Patients with degree of severity III and IV should avoid a pregnancy, in stage I and II under common control by the internist and obstetrician the pregnant patient may not have any scruples to carry to full term.
