Abstract

Abstract: Background: The penicillin therapy of β hemolytic streptococcal pharyngitis has aided in the decrease of rheumatic heart disease (RHD) in developing countries. Tunisia is an endemic area, however, and incidence of RHD is weakly documented. We aimed at establishing the standardized incidence rate (SIR) of RHD in Monastir governorate and at determining RHD prevalence among hospitalized patients in two cardiology departments. Methods: From the regional register of Monastir Hospital morbidity, we have selected newly diagnosed patients with RHD, residents of Monastir, and hospitalized to the 2 cardiology departments between 2000 and 2013 (2001 not included). Findings: We studied 676 newly admitted patients. We estimate 1060 to be the number of new annual RHD cases in Tunisia. The SIR per 10 5 person-years was 10.97, being 9.3 in men and 19.1 in women, respectively. We have notified a negative trend of crude incidence rate/10 5 Inhabitants (Inh) (CIR) ( r = − 0.23, p < 10 − 3 ), and a strong positive correlation between age and CIR/10 5 Inh ( r = 0.989, p < 10 − 4 ). RHD lethality was 1%. We have registered 728 hospitalizations for RHD, representing 2.5% of all cardiology hospitalizations [95% CI: 2.3–2.7%], with a prevalence for 13.3% for women aged 15–29 years. The median hospital stay was 9 days (IQR: 5–15). Conclusion: Our results confirm the RHD incidence decrease, consistent with epidemiological transition in Tunisia. We have also emphasized on the close trend of RHD with age and the predominance of RHD among women especially at the procreation age.
