[Indications for ACE inhibitors in the postinfarct period].

Prognosis of patients post-myocardial infarction depends largely on the degree of left ventricular dysfunction, which results from loss of contractile tissue and remodeling of infarcted and surviving myocardium. This remodeling process may result in chronically progressive dysfunction and ultimately in heart failure. Next to mechanical determinants humoral control of hypertrophy, dilatation and qualitative changes of surviving myocardium are discussed.

[QT/QS2 index in patients with arterial hypertension, mitral valve prolapse and hyperthyroidism].

QT/QS2 ratio has been assessed in 26 patients with both borderline and mild hypertension and mitral valve prolapse syndrome (19 patients), and hyperthyroidism (16 patients) in comparison with method control groups. The following polycardiographic parameters have been analyzed: QT, QTp, QS2, QT/QS2, and QTp/QS2. Higher values of QT/QS2 ratio have been noted in patients with mitral valve prolapse syndrome and hyperthyroidism than that in the control group.

[Autonomic regulation of the circulatory system in early type I diabetes].

In the group of 16 men with controlled, type I diabetes lasting up to 24 months, simple tests for assessment of autonomic regulation of the circulatory system such as a deep breathing test, Valsalva's manoeuvre and a tilt trial have been performed. Variations of systolic and diastolic blood pressures as well as heart rate have been studied. The control group consisted of 22 young, healthy men.

[Echocardiographic assessment of left ventricular function in patients with early type I diabetes].

M-mode, resting echocardiographic examination has been performed under 2-D control in 19 patients (mean age-26 years) with controlled, type 1 diabetes lasting up to 2 years (D group). The control group (C) consisted of 20 healthy men (average age-25 yrs). Greater cardiac index has been stated in D group (p less than 0.

[Effects of isometric exercise on left ventricular function assessed with polycardiography in patients with early type I diabetes].

15 patients with controlled type 1 diabetes lasting up to 24 months underwent the study. The control group consisted of 22 healthy men. Noninvasive examinations were carried out at rest and during a 3-minute isometric exercise of a load equal to 30% maximal effort.
