RESUMO
BACKGROUND: Endocarditis is a potentially life-threatening infectious disease associated with significant morbidity and mortality and an escalating incidence in recent decades. In this study, as a part of the global burden of disease (GBD) 2019 study, we intend to report endocarditis burden in Iran at national and provincial levels from 1990 to 2019. METHOD: This study was conducted using GBD 2019 study data on endocarditis from 1990 to 2019. We gathered incidence, prevalence, disability-adjusted life years (DALYs), and mortality rates in Iran and its 31 provinces by sex and age groups as epidemiological indices for endocarditis burden. Further decomposition analysis was also performed to delineate the endocarditis new cases trend. RESULTS: On the country scale, age-standardized incidence rate (ASIR), age-standardized prevalence rate (ASPR), age-standardized mortality rate (ASMR), and age-standardized DALYs rate were (16.5 (95% uncertainty interval 13.7 to 19.8), 3.4 (2.9 to 4.1), 0.6 (0.5 to 0.9), and 14.4 (12.0 to 21.1) in 2019, respectively. Decomposition analysis showed that only 59.2% of the overall new cases increase (114.1%) was caused by the incidence rate change. All estimated age-standardized rates were higher in men in 1990 and 2019 with a ratio of 1.1-1.5. CONCLUSION: The ASIR and ASPR of endocarditis increased, and the ASMR and age-standardized DALYs rate declined over the past 30 years in Iran, nearly all the provinces followed the same pattern with North Khorasan having the Highest ASIR, ASPR, ASMR, and DALYs rates in both years. High systolic blood pressure (SBP) had the greatest attributed burden among risk factors.

BACKGROUND: Atrial septal defect (ASD) is one the most prevalent forms of congenital heart disease in adults. Closure of ASDs eliminates left-to-right shunt and reduces right heart volumes, but the effects of ASD closure, on the left ventricle (LV) and mitral valve competence are somewhat inconsistent. Therefore, we designed this study to evaluate the early effect of percutaneous closure of ASD on LV function and mitral regurgitation (MR) severity. METHODS: In this prospective study, we enrolled 32 patients with ASD secundum who underwent percutaneous device closure in Tehran Heart Center. We used transthoracic and transesophageal echocardiography (TEE) before the procedure and TTE 24 hours after the procedure, then compared obtained LV parameters before and after the procedure. RESULTS: LV end-diastolic diameter (LVEDD) increased significantly from 44.8 ± 2.4 to 45.8 ± 2.8 (P < 0.001). LV end-systolic diameter (LVESD) also increased but was statistically insignificant (P = 0.063) and LV ejection fraction (LVEF) remained nearly unchanged. Highest alteration was in right ventricular systolic pressure (12.4% decrease; P < 0.001) and mitral early Doppler/tissue Doppler velocity ratio (E/E') (9.7% increase; P = 0.010). The change in MR severity was insignificant using Wilcoxon signed-rank test (P = 0.157). CONCLUSIONS: We concluded that systolic functions do not change immediately. However, LVEDD and E/E' will increase immediately, resulting from the passage of all blood from the LA into the LV in the early diastole just after closure. We also observed the positive effect of device closure on reducing right ventricular systolic pressure, and at least it does not worsen MR early after the procedure.

BACKGROUND: Preoperative coronary artery disease risk factors (CADRFs) distribution and pattern may also have an important role in determining major adverse cardiovascular events (MACEs). In this study, we aimed to evaluate the CADRFs distribution and trend over 10 years and also the long-term outcome of CABG in different age-sex categories. METHOD: In this registry-based serial cross-sectional study, we enrolled 24,328 patients who underwent isolated CABG and evaluated the prevalence of CADRFs according to sex and age. We used inverse probability weighting (IPW) to compare survival and MACE between the sexes. We also used Cox regression to determine each CADRFs effect on survival and MACEs. RESULTS: In general, DLP (56.00%), HTN (53.10%), DM (38.40%), and positive family history (38.30%) were the most frequent risk factors in all patients. Prevalence of HTN, DLP, DM, obesity, and positive family history were all higher in women, all statistically significant. The median follow-up duration was 78.1 months (76.31-79.87 months). After inverse probability weighting (to balance risk factors and comorbidities), men had lower MACEs during follow-up (HR 0.72; 95% CI 0.57-0.91; P value 0.006) and there was no significant difference in survival between sexes. DM and HTN were associated with higher mortality and MACEs in both sexes. CONCLUSION: Although DLP is still the most frequent CADRF among the CABG population, the level of LDL and TG is decreasing. Women experience higher MACE post CABG. Therefore, health care providers and legislators must pay greater attention to female population CADRFs and ways to prevent them at different levels.
