Twenty-three Mannich mono- and bis-N-bases, derivatives of isatin beta-thiosemicarbazone (IBT), were synthetized. Eighteen of these were tested for their inhibitory effect on the replication of vaccinia virus (IHD strain) in cultures of chick embryo fibroblasts. All the compounds studied showed antiviral activity, demonstrated by the agar-diffusion method (screening). The concentrations that reduced the number of viral plaques to 50% (PRD50) and the values of the therapeutic index (Th.i.) of the compounds tested were determined by the methyl-cellulose technique. The results obtained permitted analysis of their pharmaceutical effect relative to the chemical structure of the molecule, under the described experimental conditions.

In 500 cases (379 men and 121 women) of ischemic heart disease, including 428 patients with myocardial infarction and 72 -- with imminent infarction, blood lipid levels were determined. Blood samples were taken on fasting, by the end of hospitalization, from patients with myocardial infarction on the 18th-21st day of disease, and from those with imminent infarction after cessation of pain. In 152 patients (30.4%), including 87 with infarction and 65 with imminent infarction, disturbances in the blood lipid pattern were found and classified according to Fredrickson. When expressed as percentage against the material of 152 patients with blood lipid disturbances, type II A was found in 103 cases (67.8%), type II B -- in 25 cases (16.4%), and type IV -- in 24 cases (15.8%). When calculated against the whole material of 500 patients, type II A accounted for 20.6%, type II B -- for 5%, and type IV -- 4.8% of cases.

In 69 patients with ischemic heart disease the left ventricular functional state, especially contraction disturbances, was assessed by means of direct methods and polycardiographic measurements. The patients were divided into groups depending on the number of vessels affected by atheromatosis. In direct measurements the following values were determined: the rate of rise of intraventricular pressure--dP/dt max., the interval t-dP/dt max, the index (see article). In polycardiographic determinations the isovolumetric contraction time (ICI), the pre-ejection period (PEP) and the coefficient consisting of PEP in the numerator and ejection time (ET) in the denominator (PEP/ET) were calculated. The degree of changes in direct and polycardiographic parameters depended on the number of vessels affected by the atherosclerotic process. The index (see article) was most sensitive to changes in the contractility. The correlation was statistically significant for all parameters compared in the group of patients with lesions in three coronary arteries and myocardial infarction. In the remaining groups the correlations differed and a statistically significant correlation was demonstrated between particular parameters. The correlation was best between direct measurements and ICT and the PEP/ET index.

The aim of this study was to assess the diurnal variability of heart rate during VT. For the purpose of this investigation VT was considered to be a minimum of 3 consecutive ventricular beats in duration at a rate more than 100 bpm. From the group of 287 patients with VT during 24-hour ECG monitoring, a selection was made of 52 patients in whom episodes of monomorphic VT occurred in the day-time and night-time without any changes of the QRS morphology. Thirty one patients had ischemic heart disease, 10--dilated cardiomyopathy, 2--mitral valve prolapse and 10 patients had no evidence of heart disease. In these patients the rate of VT (HR-V), basic heart rate (HR-S) before VT, and coupling interval (CI) of VT initiating beat were measured during day-time and night-time. The mean VT rate was 170 +/- 34 bpm during day-time and 149 +/- 36 bpm during night-time (p < 0.001). The mean sinus rhythm rate was significantly (p < 0.001) greater during day-time (88 +/- 16 bpm) than at night (78 +/- 19 bpm). There was significant difference in the mean values of the CI between day-time and night-time (504 +/- 122 vs 589 +/- 181 ms). A significant correlation was noted between HR-V and HR-S at night (r = 0.73; p < 0.001) but not during day-time (r = 0.38). Thus, HR-V similarly as HR-S is greater during day-time than during night-time. Diurnal variability of HR-V may be related to changes in autonomic nervous system tone.

A 24-hour Holter ECG was registered in 130 patients with the ischemic heart disease with or without the history of myocardial infarction treated in out-patient clinic. Two hundred thirty seven episodes of myocardial ischemia were detected. These episodes developed between 6.00 and 8.00 a.m., 12.00 and 4.00 p.m., and 6.00 and 8.00 p.m.

In 126 patients with clinical ventricular tachycardia and/or fibrillation, ischemic heart disease and repetitive and/or frequent ventricular ectopic beats long-term therapy guided by Holter ecg was assessed. Criteria for efficacy of antiarrhythmic drugs were following: 1) > 75% decrease in ectopic beats, 2) elimination of salvos, 3) > 90% reduction of couples and R/T and 4) reduction of multiformity up to 2 forms. They were fulfilled in 71% of patients (responders). During follow-up 1-49 months, mean 20, rate of sudden death was lower in responders as compared with nonresponders (p < 0.05). However, suppression of ventricular ectopic beats was not predictive for a favorable outcome, because the incidence of arrhythmic events and total cardiac death was similar in the two groups.

In 1983-1988, the results of conservative and surgical treatment of patients with atherosclerotic ischemia of the lower limbs were assessed with the aid of a questionnaire. A possibility of prognosis was assessed with the use of mathematically processed data obtained with such approach. An effect of clinical symptoms (intermittent claudication distance, resting pain, necrosis) and stage of the disease (duration, K/R index) and risk factors (blood cholesterol, triglycerides, diabetes mellitus, ischemic heart disease, arterial hypertension) on the result of surgical treatment was analysed. The obtained results suggest that clinical symptoms and risk factors may predict the results of surgical treatment in the atherosclerotic ischemia of the lower limbs.

In the presented article, the course and results of anatomical correction of transposition of great arteries (TGA) in 7 neonates (2 females and 5 males) with mean body mass of 3250 g and 2 to 5 days old (mean 3 days) are reviewed. Surgery was performed in moderate hypothermia. St. Thomas cold cardioplegia was used. Mean aortic clamping time was 70 min (55-115), and the time of extracorporeal circulation was 165 min (117-210). Low cardiac output in all patients in the postoperative period required prolonged mechanical ventilation and positive inotropic drugs. Out of 7 patients operated, two died (29%). The cause of death in both cases was myocardial ischemia of right ventricle. The other 5 patients were discharged after healing of operational wound. In the control echocardiographic examination performed 3 to 12 months postoperatively, apart from one case of moderate pulmonary artery stenosis, no other haemodynamically significant complications were noted.

A rate of Q wave regression was assessed in 72 patients with ischaemic heart disease, including 46 patients after the infarction of the inferior wall and 26 patients after anterior wall infarction. All patients were followed-up for two years. Complete regression of Q wave was noted in 19 patients (41.3%) after inferior wall infarction and in one patient (3.8%) after anterior wall myocardial infarction. Partial regression of Q wave was seen in 9 patients (19.6%) after inferior wall, and in 2 patients (7.6%) of patients with anterior wall myocardial infarction. It seems that the regression of Q wave in ECG does not improve prognosis in these patients. Six out of 10 deaths which occurred in the followed up group of patients involved those in whom no electrographic features of the past myocardial infarction were seen.

The investigations were aimed at the objective evaluating of trimetazidine efficacy in the treatment of 30 patients with arterial hypertension and ischemic heart disease carried out in non-invasive manner. It was found that trimetazidine complies with several requirements for the effective drug administered to the patients with hypertension associated with ischemic heart disease as it: (a) reduces peripheral resistance and exerts favourable effect on the walls tonus of larger arteries; (b) lowers specifically post-exercise arterial pressure and improves resting arterial pressure; (c) reduces demand for oxygen; (d) is safe, and well tolerated by 83% of the treated patients in daily dose of 60 mg.
