[Use of fourier row as a method for analyzing the course of circadian heart rate in patients with left ventricular ejection fraction impairment].

The circadian heart rate course was assessed in 3 groups of patients with left ventricular ejection fraction (LVEF) 10-15%, 20-25% and 30-35%. The study comprised 36 persons. In 9 patients heart failure was due to MI and in 17--to dilated cardiomyopathy.

[Early results and many years of observing treatment of unstable angina].

Immediate effect of PTCA and CABG for unstable angina then followed-up for PTCA and CABG several years are analyzed in 112 patients selected out of 204 unstable angina patients hospitalized from 1990 to 1991. Fifty three patients, aged 25-68 (mean 51) were assigned to PTCA, fifty nine aged 33-69 (mean 53) were subjected to CABG. Both groups comprised of 72% and 83% males respectively.

[Congenital methemoglobinemia found in an adult. Case report].

Cyanosis in a 36 year old patient which persisted 20 years after a successful surgical closure of her patent foramen ovale has been finally diagnosed as due to congenital methemoglobinemia: a 28% level of methaemoglobin and no activity od NAD-dependent methaemoglobin reductase were found. Erythrocyte antioxidative system was studied i.e.

[Value of endomyocardial biopsy in the assessment of the degree of the changes in myocarditis].

Right ventricular diagnostic biopsy was performed in 25 patients (12 females and 13 males) aged 19-48 (mean 32) with suspicion of acute or subacute myocarditis for definitive diagnosis verification and to determine indications for therapy with corticosteroids or azathioprine. 3-4 specimens taken from different sites of ventricle were estimated under the light microscope according to Dallas classification distinguishing active myocarditis with or without fibrosis from borderline myocarditis with inflammatory infiltration not causing myocytes damage. Routine clinical and laboratory tests, echocardiographic examination, ECG Holter monitoring and nuclear examination to evaluate left ventricular ejection fraction were performed in all patients.
