[Incidence of hyperuricemia in atrioventricular block. Systematic study of 158 cases which required implantation of an isotopic cardiac pacemaker].
This is a study of 158 patients in whom the placement of an isotopic cardiac pacemaker was indicated; this procedure was carried out Broussais Hospital between 1970 and 1975. These patients, whose mean age was 39 (84 males, 47 females, 12 young men and 15 young women) were examined for uricaemia, and the levels compared with the mean for control population. The results were as follows: 91% had uricaemia at a level higher than the controls. Of these, 61% had uricaemia above 70 mg/l in the men and youths of over 15 years of age, and above 60 mg/l in the women and 50 mg/l in the adolescents. The highest uric acid levels were found in adults with post-operative atrio-ventricular block following surgical correction of a congenital cardiac abnormality, and also in children and adolescence with block which appeared to be congenital.

[Occurrence of hyperuricemia in atrioventricular block. (Results of a study of 158 patients with isotopic pacemaker implantations)].
The frequency of hyperuricemia is high in these patients with heart block, whose mean age is 39. 91% have serum uric acid levels above the normal range and 61% present "hyperuricemia," according to "gouty risk" criteria. The mean uric acid level, before surgery, of the patients whose total heart block follows "open-heart" is the highest in our statistics.

[Survival time of patients with cardiac pacemakers (author's transl)].
A comparison between the life expectancy of patients with pacemakers and that of a control population of similar structure shows a parallel course, although originally, after a postoperative phase of 2 months, the mortality rate of the patients with pacemakers was higher. Today the results are considerably better. Implantation of pacemakers is one of the greatest cardiological advances in the last 10 years for the effective treatment and prevention of cardiac arrest in atrioventricular block. The significance of this type of therapy becomes understandable if the fact that the mortality of Adams-Stokes attacks used to be about 50% is taken into consideration. In France, about 5000 persons each year have Adams-Stokes attacks.
