Serum linoleic acid and cardiovascular death in postinfarction middle-aged men.

Linoleic acid in serum total lipids was the first variable in the stepwise regression analysis of metabolic, nutritional and cardiovascular factors in a secondary preventive study of postinfarction middle-aged men. It was followed in the regression analysis where the dependent variable was cardiovascular death by previous myocardial infarction, heart volume index and hyperlipoproteinaemia. Linoleic acid was the only fatty acid entering the regression. Unlike other fatty acids, it exhibited by its low percentage an accumulation of deaths. The decreased percentage of linoleic acid was also evident in the comparison of fatty acid patterns of cardiovascular deaths to age- and triglyceride-matched men free from ischaemic heart disease. This study confirms prospective associations found in previously healthy men. Conclusions are drawn about the relevance of low serum linoleic acid to long term prognosis after MI.

[Interstitial radiotherapy].

At first the causes of the renaissance of interstitial radiotherapy are cited. The physical and radiobiological aspects about modern radionuclides are presented and compared with conventional methods. The advantages of these modern treatment schedules are demonstrated, especially in terms of radiation protection. Indications and methods of modern interstitial radiotherapy with I-125 seeds and Ir-192 wires are pointed out. Finally published results are mentioned.

Metabolic studies in postmyocardial infarction patients.

One hundred and seven patients registered in the secondary preventive programme in Prague 4 were followed up for an average period of 3 years. The endpoints of the study were taken as criteria of the progression of clinical atherosclerosis (non-fatal myocardial infarction, cardiovascular death). The authors tried to detect the causes responsible for the high prevalence of impaired glucose tolerance, diabetes and hyperlipoproteinaemia. They analyzed the interrelationships of food intake, insulin secretion, serum fatty acids and lipoprotein phenotypes. There were 6% of non-fatal myocardial reinfarctions and 13% of cardiovascular death after 3 years. Multiple regression analysis identified the following 3 factors closely associated with cardiovascular death: 1) history of myocardial infarction 2) low proportion of linoleic acid in total lipids 3) hyperlipoproteinaemia. The authors show that analysis of the relationships of triglycerides, insulin and serum fatty acids could be of value for identifying the factors involved in a faster progression of atherosclerosis.

[Combined chemo- and radiotherapy in small cell bronchogenic carcinoma].

During a period of 3 years 25 patients with small cell bronchogenic carcinoma were treated with combination chemotherapy and radiotherapy. The regimen was composed of adriamycin, cyclophosphamide and vincristine (ACO). After the first three cycles of combination chemotherapy-radiotherapy treatment was given to the primary tumor, the regional lymph nodes, the mediastinum and clinically involved cervical nodes. All patients showed a complete or partial regression of tumor. The median duration of response of patients with limited disease was 12 months, for those with extended or disseminated disease 8,6 months. Median survival from start of therapy was 14 months for those with limited disease at presentation and 10,9 months for those presenting with disseminated disease. The data were compared with those of other studies and discussed.

Incidence of circulatory arrest in patients with acute myocardial infarction in coronary unit. Mechanism of their genesis and factors conditioning successful resuscitation.

The incidence, circumstances, and mechanism of development of cardiac arrest in 786 patients with myocardial infarction treated at a coronary care unit within a five-year period were studied and clinical factors are analysed with respect to success of resuscitation. One or more episodes of cardiac arrest occurred in a total of 156 patients (19.8%). Of these, 25 (16.0%) were successfully resuscitated and 131 (84.0%) died. At the clinical ward where the patients had been transferred after the acute stage, cardiac arrest occurred in additional 22 patients, of whom two were successfully resuscitated. Thus, the total number of successfully resuscitated patients throughout the five-year period was twenty-seven. The results of resuscitation were poorer in elderly patients, in those with anterior infarction, and above all in patients with severe symptoms of mechanical heart failure. Anamnestic factors (chronic angina pectoris, previous myocardial infarction, hypertension, diabetes mellitus, ischaemic disease of the lower limbs) were not significantly associated with the results of resuscitation. Primary ventricular fibrillation was the principal mechanism of cardiac arrest in 24 of the 27 patients successfully resuscitated, and its total incidence in the investigated group was 3%. The prognosis of resuscitation in patients with primary ventricular fibrillation was very good, and in all of them the resuscitation was successful and permanent.
