Abstract
Purpose Infective endocarditis (IE) remains a disease with high morbidity and mortality. The aim of this study was to determine the clinical characteristics and echocardiographic features of patients with IE. Methods We analyzed patients with either definitive or probable diagnosis of IE who were hospitalized in a teaching hospital in Mashhad, Iran between June 2011 and January 2020. Patients who survived were followed up by echocardiography for at least 6-month after hospital discharge. Results A total of 82 cases with IE were included of which 62 (75.6%) received definitive diagnosis. The mean age was 39.7 ± 18.7 years and 52 (63.4%) were male. The most common preexisting structural cardiac abnormality that predispose patients to IE were congenital heart diseases (28 %) of which bicuspid aortic valve was more common (n = 12, 14.6%), followed by ventricular septal defect (n = 9, 11%) and Tetralogy of Fallot (TOF) (n = 2, 2.4%). Three (3.6 %) cases had rheumatic heart disease and 12 (14.6 %) were injecting drug users. The most common causative pathogen was Staphylococcus aureus, detected in 7 (19.4%) cases. Follow-up echocardiography revealed right or left ventricular failure in 10 (12.1%) cases. Cardiac complications occurred in 41 (50%) cases and systemic complications in 63 (76.8%). All-cause mortality was 41.5% (n = 34) and 6 (18.1%) patients died due to cardiovascular complications. Conclusions The short- and long-term prognosis in IE was poor and the predictors for in-hospital and 1-year mortality were defined as heart failure and septic shock. Congenital heart disease and intravenous illicit drug using (IVDU) were the most common predisposing condition which may necessitate a revision in the IE prophylaxis recommendations.

The Global, Regional, and National Burden and Trends of Infective Endocarditis From 1990 to 2019: Results From the Global Burden of Disease Study 2019. Front Med (Lausanne) 2022; 9:774224. [PMID: 35355601 PMCID: PMC8959916 DOI: 10.3389/fmed.2022.774224] [Citation(s) in RCA: 21] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Accepted: 01/28/2022] [Indexed: 12/23/2022] Open
Abstract
Introduction Infective endocarditis (IE) presents with increasing incidence and mortality in some regions and countries, as well as serious socioeconomic burden. The current study aims to compare and interpret the IE burden and temporal trends globally and in different regions from 1990 to 2019. Methods Data on the incidence, deaths and disability-adjusted life years (DALYs) caused by IE were extracted and analyzed from the Global Burden of Disease Study 2019. Estimated annual percentage changes (EAPC) were adopted to quantify the change trends of age-standardized rates (ASRs). Besides, potential contributors of serious IE burden were also evaluated including age, gender, social-demographic index (SDI), and age-standardized incident rate (ASIR) in 1990. Results Globally, the number of IE cases and deaths has increased sharply during the past 30 years from 478,000 in 1990 to 1,090,530 in 2019 and from 28,750 in 1990 to 66,320 in 2019, and both presented an upward temporal trend annually (EAPC:1.2 for incidence and 0.71 for death). However, the EAPC of age-standardized DALYs demonstrated a negative temporal trend despite increasing DALYs from 1,118,120 in 1990 to 1,723,590 in 2019. Moreover, older patients and men were more severely affected. Meanwhile, different SDI regions had different disease burdens, and correlation analyses indicated that SDI presented a positive association with ASIR (R = 0.58, P < 0.0001), no association with age-standardized death rate (R = −0.06, P = 0.10), and a negative association with age-standardized DALYs (R = −0.40, P < 0.0001). In addition, the incidence of IE increased in most countries during the past 30 years (190 out of 204 countries). However, the change trends of deaths and DALYs were heterogeneous across regions and countries. Finally, we discovered positive associations of the EAPC of ASRs with the SDI in 2019 among 204 countries and territories but few associations with the ASIR in 1990. Conclusion Generally, the global burden of IE is increasing, and there is substantial heterogeneity in different genders, ages and regions, which may help policy-makers and medical staff respond to IE and formulate cost-effective interventional measures.

Abstract
Aims Infective endocarditis (IE) remained a potentially fatal disease with high rate of mortality and morbidity. The epidemiology and global burden of IE are largely different between the countries. We aimed to address the epidemiological aspects of IE in a tertiary hospital in Tehran, Iran. Methods and Results Between 2006–2018, all adults patients with diagnosis of IE were enrolled in the Iranian Registry of Infective Endocarditis (IRIE). The data were analyzed using the χ2, Kolmogorov–Smirnov, and Mann–Whitney U tests. Overall, 602 patients, 407 (67.6%) men, mean age 46 ± 16 years were recruited. Positive blood culture found in 49%.The most common underlying heart diseases were: Congenital heart diseases (CHD) particularly bicuspid aortic valves (BAV) and ventricular septal defects (VSD) in 37%, followed by degenerative heart diseases :flail and mitral valve prolapse (16.3%), intravenous drug user in 12.6%, prosthetic valves in 11.1%, previous IE (8.9%), rheumatic heart diseases (RHD) in 8.4%. The most causative microorganisms were Staphylococcus aureus, Enterococci, coagulase-negative staphylococci and Streptococcus viridans. Cardiac or extra cardiac complications occurred in 56.6% of the patients. Conclusions Based on IRIE, IE occurs in the younger population in Iran with high rates of blood culture-negative IE. RHD are not the main cause of IE in Iran, CHD including BAV and VSDs, followed by prolaptic or flail mitral valve were the most common. These 2 groups can be considered a high-risk group for IE. More than half of the patients with IE had cardiac or extra cardiac complications.

Association of Vegetation Size With Embolic Risk in Patients With Infective Endocarditis: A Systematic Review and Meta-analysis. JAMA Intern Med 2018; 178:502-510. [PMID: 29459947 PMCID: PMC5876809 DOI: 10.1001/jamainternmed.2017.8653] [Citation(s) in RCA: 61] [Impact Index Per Article: 10.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/13/2022]
Abstract
IMPORTANCE Infective endocarditis is a life-threating condition with annual mortality of as much as 40% and is associated with embolic events in as many as 80% of cases. These embolic events have notable prognostic implications and have been linked to increased length of stay in intensive care units and mortality. A vegetation size greater than 10 mm has often been suggested as an optimal cutoff to estimate the risk of embolism, but the evidence is based largely on small observational studies. OBJECTIVE To study the association of vegetation size greater than 10 mm with embolic events using meta-analytic techniques. DATA SOURCES A computerized literature search of all publications in the PubMed and EMBASE databases from inception to May 1, 2017, was performed with search terms including varying combinations of infective endocarditis, emboli, vegetation size, pulmonary infarct, stroke, splenic emboli, renal emboli, retinal emboli, and mesenteric emboli. This search was last assessed as being up to date on May 1, 2017. STUDY SELECTION Observational studies or randomized clinical trials that evaluated the association of vegetation size greater than 10 mm with embolic events in adult patients with infective endocarditis were included. Conference abstracts and non-English language literature were excluded. The search was conducted by 2 independent reviewers blinded to the other's work. DATA EXTRACTION AND SYNTHESIS Following PRISMA guidelines, the 2 reviewers independently extracted data; disputes were resolved with consensus or by a third investigator. Categorical dichotomous data were summarized across treatment arms using Mantel-Haenszel odds ratios (ORs) with 95% CIs. Heterogeneity of effects was evaluated using the Higgins I2 statistic. RESULTS The search yielded 21 unique studies published from 1983 to 2016 with a total of 6646 unique patients with infective endocarditis and 5116 vegetations with available dimensions. Patients with a vegetation size greater than 10 mm had increased odds of embolic events (OR, 2.28; 95% CI, 1.71-3.05; P < .001) and mortality (OR, 1.63; 95% CI, 1.13-2.35; P = .009) compared with those with a vegetation size less than 10 mm. CONCLUSIONS AND RELEVANCE In this meta-analysis of 21 studies, patients with vegetation size greater than 10 mm had significantly increased odds of embolism and mortality. Understanding the risk of embolization will allow clinicians to adequately risk stratify patients and will also help facilitate discussions regarding surgery in patients with a vegetation size greater than 10 mm.
