Surgical treatment of patients with infective endocarditis: changes in temporal use, patient characteristics, and mortality-a nationwide study.

ABSTRACT:

Background

Valve surgery guidelines for infective endocarditis (IE) are unchanged over decades and nationwide data about the use of valve surgery do not exist.

Methods

We included patients with first-time IE (1999-2018) using Danish nationwide registries. Proportions of valve surgery were reported for calendar periods (1999-2003, 2004-2008, 2009-2013, 2014-2018). Comparing calendar periods in multivariable analyses, we computed likelihoods of valve surgery with logistic regression and rates of 30 day postoperative mortality with Cox regression.

Results

We included 8804 patients with first-time IE; 1981 (22.5%) underwent surgery during admission, decreasing by calendar periods (N = 360 [24.4%], N = 483 [24.0%], N = 553 [23.5%], N = 585 [19.7%], P = < 0.001 for trend). For patients undergoing valve surgery, median age increased from 59.7 to 66.9 years (P ≤ 0.001) and the proportion of males increased from 67.8% to 72.6% (P = 0.008) from 1999-2003 to 2014-2018. Compared with 1999-2003, associated likelihoods of valve surgery were: Odds ratio (OR) = 1.14 (95% CI: 0.96-1.35), OR = 1.20 (95% CI: 1.02-1.42), and OR = 1.10 (95% CI: 0.93-1.29) in 2004-2008, 2009-2013, and 2014-2018, respectively. 30 day postoperative mortalities were: 12.7%, 12.8%, 6.9%, and 9.7% by calendar periods. Compared with 1999-2003, associated mortality rates were: Hazard ratio (HR) = 0.96 (95% CI: 0.65-1.41), HR = 0.43 (95% CI: 0.28-0.67), and HR = 0.55 (95% CI 0.37-0.83) in 2004-2008, 2009-2013, and 2014-2018, respectively.

Conclusions

On a nationwide scale, 22.5% of patients with IE underwent valve surgery. Patient characteristics changed considerably and use of valve surgery decreased over time. The adjusted likelihood of valve surgery was similar between calendar periods with a trend towards an increase while rates of 30 day postoperative mortality decreased.

Project description:Background Monitoring of microbiological cause of infective endocarditis (IE) remains key in the understanding of IE; however, data from large, unselected cohorts are sparse. We aimed to examine temporal changes, patient characteristics, and in-hospital and long-term mortality, according to microbiological cause in patients with IE from 2010 to 2017. Methods and Results Linking Danish nationwide registries, we identified all patients with first-time IE. In-hospital and long-term mortality rates were assessed according to microbiological cause and compared using multivariable adjusted logistic regression analysis and Cox proportional hazard analysis, respectively. A total of 4123 patients were included. Staphylococcus aureus was the most frequent cause (28.1%), followed by Streptococcus species (26.0%), Enterococcus species (15.5%), coagulase-negative staphylococci (6.2%), and "other microbiological causes" (5.3%). Blood culture-negative IE was registered in 18.9%. The proportion of blood culture-negative IE declined during the study period, whereas no significant changes were seen for any microbiological cause. Patients with Enterococcus species were older and more often had a prosthetic heart valve compared with other causes. For Streptococcus species IE, in-hospital and long-term mortality (median follow-up, 2.3 years) were 11.1% and 58.5%, respectively. Compared with Streptococcus species IE, the following causes were associated with a higher in-hospital mortality: S aureus IE (odds ratio [OR], 3.48 [95% CI, 2.74-4.42]), Enterococcus species IE (OR, 1.48 [95% CI, 1.11-1.97]), coagulase-negative staphylococci IE (OR, 1.79 [95% CI, 1.21-2.65]), "other microbiological cause" (OR, 1.47 [95% CI, 0.95-2.27]), and blood culture-negative IE (OR, 1.99 [95% CI, 1.52-2.61]); and the following causes were associated with higher mortality following discharge (median follow-up, 2.9 years): S aureus IE (hazard ratio [HR], 1.39 [95% CI, 1.19-1.62]), Enterococcus species IE (HR, 1.31 [95% CI, 1.11-1.54]), coagulase-negative staphylococci IE (HR, 1.07 [95% CI, 0.85-1.36]), "other microbiological cause" (HR, 1.45 [95% CI, 1.13-1.85]), and blood culture-negative IE (HR, 1.05 [95% CI, 0.89-1.25]). Conclusions This nationwide study showed that S aureus was the most frequent microbiological cause of IE, followed by Streptococcus species and Enterococcus species. Patients with S aureus IE had the highest in-hospital mortality.

Project description:To examine temporal changes in patient characteristics, the incidence rate of surgical intervention, and the three-year mortality rate for patients undergoing surgical intervention for mitral valve stenosis (MS) from 2001 to 2021 in Denmark. Utilizing Danish nationwide registries, we identified all adult patients undergoing first-time surgical intervention for MS (2001-2021). Temporal changes in the incidence rate of surgical intervention across calendar periods were investigated (2001-2005, 2006-2010, 2011-2015, and 2016-2021). Using Kaplan-Meier estimates, we computed temporal changes in three-year all-cause mortality across calendar periods. With multivariable Cox regression analysis, we assessed the adjusted rates of mortality. We included 256 patients (median age 60.3 years, 31.3% males). A stepwise decrease in the burden of chronic heart failure was identified (2001-2005: 54%, and 2016-2021: 20%, p-value < 0.001 for trend), while the burden of atrial fibrillation seemed stable (2001-2005: 51%, and 2016-2021: 46%, p-value = 0.27 for trend). The proportion of patients with rheumatic MS was 64% in 2001-2005 and 33% in 2016-2021, p-value < 0.001 for trend. 28 patients (10.9%) had mitral valve surgery prior to the first-time surgical intervention for MS. A stepwise decrease in the incidence rate of surgical intervention was observed: 3.3 cases per million person-years in 2001-2005 and 2.2 in 2016-2021. The incidence of patients diagnosed with first-time MS remained stable over calendar periods (2001-2005: 54.5 incidences per million person-years, and 2016-2021: 41.9, p-value = 0.46 for trend). The in-hospital mortality was 8.6% and the three-year mortality after surgical discharge was 9.0%, and we found no difference over calendar periods in either crude estimates or adjusted analysis. From nationwide data across three decades, we identified that the incidence of surgical interventiondecreased significantly within the past 20 years, while all-cause mortality remained stable. The burden of heart failure decreased, while the burden of atrial fibrillation remained stable over the study period.

Project description:BackgroundThe epidemiological and clinical characteristics of infective endocarditis (IE) in mainland China, particularly following the COVID-19 pandemic, remain insufficiently understood. This study aims to examine temporal trends, clinical features, and factors influencing in-hospital mortality of IE in northern China from 2019 to 2023.MethodsThis multicenter, retrospective study included 961 patients diagnosed with IE between 2019 and 2023 across hospitals in Henan, Shandong, and Tianjin. Data were collected on demographics, comorbidities, COVID-19 status, and treatment modalities. Risk factors for in-hospital mortality were identified using logistic regression and Cox proportional hazards models. The effect of surgical intervention was assessed through propensity score matching.ResultsIn-hospital mortality increased from 7.7% in 2019 to 26.4% in 2023, with an average annual growth of 38% (P = 0.008). The proportion of IE patients aged 65 years and older significantly increased, with this age group exhibiting the highest mortality rate (37.3%) by 2023. Surgical intervention was associated with a 91% reduction in in-hospital mortality (HR 0.09, 95% CI 0.05-0.15, P < 0.001). Independent risk factors for mortality included low left ventricular ejection fraction (LVEF), elevated heart rate (HR), cerebral hemorrhage, the use of vasoactive drugs and the requirement for continuous renal replacement therapy (CRRT).ConclusionIn-hospital mortality due to IE in northern China has risen substantially since 2019, particularly in elderly patients and those with comorbid conditions. There was no significant change in overall per capita hospitalization costs or length of stay. Surgical intervention significantly improved survival outcomes. Additionally, patients who have been infected with COVID-19 twice had an 81.3% increased risk of death. The results of this study provide important data into the epidemiological and medical burden of IE in mainland China since the COVID-19 epidemic.
