[ANF--atrial natriuretic factor].

Is produced at the right atrium and is acting upon four types of receptors. The main effects of ANF are: renal effects, by rapid increasing and prolongation of glomerular filtration; neuroumoral effects--the inhibition of renin-angiotensin system and of the release of aldosterone; effects upon the vascular wall, with vasodilatation; another effect is the regulation of the hydrosalin balance. The therapeutical endpoints of ANF are related to its action in some diseases like: cardiac failure, arterial hypertension, myocardia infarction, paroxysmal arrhythmias; in some of them it is a very fiable predictive marker. ANF represents o neuroumoral mechanism which play an important role in functional regulation of the cardio-vascular system.

[Cardiac amyloidosis. A case report].

The paper presents the morphoclinical picture in cardiac amyloidosis to a 50 years old man admitted at Iasi Cardiology Center with progressive chronic cardiac failure, the patient having recent history of restrictive cardiomyopathy. It was made a complete cardiovascular evaluation including the right cardiac catheterization for endomyocardial biopsy. The biopsy specimens were fixed in buffered 10 % formalin, followed by routine paraffin embedding, and were stained with haematoxylin-eosin, elastic Van Gieson and sulphated blue Alcian for amyloid evaluation. The amyloid deposits were evidentiated in the interstitium and into vascular walls of the biopsy, pointing the importance of the morphological exam for amyloidosis diagnosis.

[The effect of rehabilitative treatment on left ventricular performance in myocardial infarct patients in the convalescent phase].

There have been studied the left ventricular performance at 71 patients (66 B/5 F) with myocardial infarction during the convalescence period, admitted in the Department of Clinical Rehabilitation in a period of time between 01.01.1992-31.10.1993. Mean age was 49.9 +/- 4.3 years. Most of the patients had antero-septal (33 patients--46%) and posteroinferior (29 patients--41%) myocardial infarction. The left ventricular performance was assessed by the study of exercise electrocardiography (TTI), of the systolic intervals using the Weissler equations and echocardiography (M-mode and 2D). After the period pf training (21 days), we saw a significant reduction of TTI at the same step of the test. The systolic intervals significantly modified after the training were PEVS (p < 0.025), PEP/PEVS (p < 0.025), EF (p < 0.025). EF and SF measured echographically do not indicate significant differences after the training. There are not important improvements of the wall motion disorders at the end of the period.
