The Bucharest Multifactorial Prevention Trial of Coronary Heart Disease--ten year follow-up: 1971-1982.

The trial begun in 1971 and the paper brings the results after a ten-year follow-up. Both the intervention and control group contained 5000 men with a similar socioeconomic and professional structure; the intervention group was examined every six months in the first 5 years and annually in the second phase. The control group was examined "only after" 5 years and a second time at the final moment.

The Bucharest multifactorial prevention trial. The changes of morbidity and of general and specific mortality.

The paper presents the results of the Bucharest multifactorial prevention trial of coronary heart disease, concerning changes in cardiovascular morbidity and mortality during the first 5-year-period of follow-up. The age adjusted 5-year-rates disclose important reductions in the intervention group in comparison with the control one: for hard events (myocardial infarction, stroke, acute coronary insufficiency)--by 41%; for myocardial infarction--by 35%; for coronary mortality--by 38%; for stroke--by 39%; for cardiovascular mortality--by 30%. The decrease of hard events, myocardial infarction and stroke incidences are statistical significant.

The Bucharest multifactorial prevention trial of coronary heart disease. General methodology and risk factor correction after five year follow-up (1971-1977).

Both the intervention and the control group included each 5000 men aged 40-60 years, randomly selected by their home address in five districts of the city of Bucharest. The intervention group underwent an "at entry" examination for risk factor detection (high serum cholesterol, high blood pressure, overweight, diabetes, minor ECG abnormalities, family history) and subsequently a five-year multifactorial intervention aimed to reduce the risk factors. Both groups were followed up in this lapse of time for major end-points: myocardial infarction, stroke, sudden death.

Significance of T and B lymphocytes in different chronic internal diseases with immune processes.

The T and B lymphocytes were determined by the rosette test in the peripheral blood of 100 patients with internal chronic diseases with immune processes such as: chronic hepatitis, systemic lupus erythematosus, myasthenia gravis, chronic lymphocytic leukemia and lymphosarcoma. The values obtained were compared with those in 10 controls. The mean per cent values of the T lymphocytes in the controls were 33 (29-38%) and of the B lymphocytes 25.
