The long term prognosis of infective endocarditis.

Three problems hamper the prognosis of patients who survive the initial phase of infective endocarditis (IE): the rate of IE recurrence is 0.3-2.5/100 patient years, about 60% of patients will have to be operated on at some time, 20-30% during the initial stay, 30-40% during the following 5-8 years; five-year survival after the hospital phase is about 75% in previous reports and 85% in more recent papers.

[Relation of alcohol consumption and blood lipids and apolipoproteins--a study of a population of 3,897 wage-earners from the Lyon region].

Between June 1982, and September 1984, a survey was conducted among 3,897 employees in the Region of Lyon to study the relationship between alcohol consumption and serum concentrations of total cholesterol and triglycerides. In 400 randomly selected men, the following data were also obtained: concentrations of the cholesterol of the high density lipoproteins (HDL) and of their subfractions, and concentrations of the apoproteins A-I, A-II and B. All these biochemical concentrations increased, more or less, with alcohol consumption.

[Prognosis of surgically treated infectious endocarditis].

The prognostic factors in infective endocarditis patients who underwent surgery in the acute stage were evaluated from the records of 189 cases of native valve endocarditis operated upon between 1970 and 1986. Surgery had been performed before June 30, 1982 in 105 patients (group 1) and since July 1, 1982 in 84 patients (group 2). Group 2 only differed from group 1 in that the proportion of negative blood cultures was lower (13.

[Sports and blood pressure: association in a population of wage-earners].

In a cross-sectional epidemiological survey, we examined the association between the practice of sports and blood pressure (BP). The study included 3,388 male employees (representing 90.1% of the target population) who were questioned about their habitual sports activity, in terms of average duration per week and intensity.

[Prognostic value of the exercise test performed less than 40 days after the first infarction].

Stress testing was performed in 159 men (mean age 49.83 years) between the 10th and 40th day after primary myocardial infarction. The average work achieved was 79 watts with a heart rate of 121/min, systolic blood pressure of 169 mmHg, and a double product of 20 544.
