[Results of cardiac pacing: report of 188 patients]. / Résultats de la stimulation cardiaque définitive: a propos de 188 malades.

ABSTRACT

BACKGROUND: Indications for permanent pacing are currently well codified. This treatment may, however, present complications AIM: To report the results of cardiac pacing and to identify predictive factors of pacing's complication. METHODS: We conducted a retrospective study of 188 consecutive patients admitted to the cardiology department of Mongi Slim university hospital in La Marsa between January 2005 and June 2011 and implanted with a single or dual chamber pacemaker. RESULTS: In our study, we had 92 men and 96 women (sexratio= 0.95). The mean age was 70.21 ± 13 years. The indication for cardiac pacing was a high degree heart block in 74.46% of cases and a sick sinus syndrome in 15.95% of cases. The degeneration conduction tissue was the main etiology (72.34% of patients). Success implantation was obtained in 98.4%of cases. The main operative complication was the pneumothorax in 3 patients (1.59% of cases). At Long term, cumulative survival rate was 78.95%. Only operating time affects significantly the rate of early complications (p<0.001). Late complications were related to the valvular heart disease (p = 0.007), the ischemic etiology (p = 0.05), the oral antivitamine K treatment (p = 0.04) and the occurrence of early complication (p = 0.002). CONCLUSION: Our hospital, which is considered as a small Center of cardiac pacing (less than 80 procedures/year) had a low complication rate as well as big centers.
