[Cardiovascular risk factors in essential hypertension].

Authors analysed the cardiovascular risk factors, their relationship to each other, the rate of multiple appearance in 1476 patients (774 men, 702 women) with essential hypertension. They produced a special questionnaire and risk factor analysing program for performing static and dynamic investigations on the base of international and domestic experiences. The data of their investigations verified, that the occurrence of obesity is very frequent and is associated with abnormal cholesterol and triglyceride values.

Haemodynamic effect of nitroglycerin spray.

1. It is a reliable nitroglycerin (NTG) form influencing circulation and haemodynamics like other nitroglycerin products, 2. It is easily applicable, 3.

[Clinical value of body surface mapping in the diagnosis of ischemic heart disease].

A series of 137 patients suffered in clinically documented angina pectoris were analyzed by 12-lead exercise ECG, exercise body surface potential mapping and exercise thallium scintigraphic methods and the results were compared to that of selective coronary angiography and left ventriculography. If coronary artery stenosis were considered to be significant in the presence of more than 70% vessel narrowing, the sensitivity figures were 76, 93 and 88% for exercise 12-lead ECG, exercise body surface potential mapping and exercise thallium scintigraphy, respectively. In considering 50% coronary artery narrowing to be significant, the same figures were 78, 94 and 89%.

Comparative evaluation of the effect of balloon dilatation by exercise precordial mapping and exercise 201-thallium scintigraphy.

Precordial exercise electrocardiographic mapping and exercise 201-thallium scintigraphy were simultaneously used on sixteen patients before, shortly after and three months after percutaneous transluminal coronary angioplasty (PTCA) to evaluate the immediate and late results of the intervention. In spite of the limited number of observations, positive exercise precordial mapping and or a reversible 201-thallium perfusion defect after PTCA seem to be indicative of failure of balloon dilatation or of development of restenosis in a given coronary artery. "Reverse minimum", that is the minimum in the resting precordial map which disappears on exercise, may be a sign of segmental coronary artery occlusion and well functioning collateral supply.

Non-invasive assessment of elevated ventricular diastolic pressures in patients with ischaemic heart disease.

For non-invasive assessment of the diastolic pressures of both ventricles, 50 patients with ischaemic heart disease were studied by combined mechano- and echocardiography. Twenty one patients had pulmonary congestion, eleven had acute mitral regurgitation and 18 had signs of left and right heart failure. All patients had undergone cardiac catheterization.

Hypoadrenia following adrenal venography in Cushing's disease.

Three patients with Cushing's disease are reported. In two patients the hyperfunction of the adrenal glands ceased following selective adrenal venography, moreover hypoadrenia has developed. In the third case necrosis following venography was proved by surgery and confirmed by histology.

Local perfusion chemotherapy for gestational malignant trophoblastic tumours.

Two cases are presented where malignant trophoblastic tumour of the uterus was successfully treated with pelvic cytostatic perfusion. Local drug perfusion is suggested as a possibly effective treatment in case systemic chemotherapy fails and the patient wishes to bear a child.
