BACKGROUND: Early extubation (EEx) is defined as the removal of the endotracheal tube within 8 h postoperatively. The present study involved determining the availability and threshold of the vasoactive-inotropic score (VIS) for predicting EEx in adults after elective rheumatic heart valve surgery.
METHODS: The present study was designed as a single-center retrospective cohort study which was conducted with adults who underwent elective rheumatic heart valve surgery with CPB. The highest VIS in the immediate postoperative period was used in the present study. The primary outcome, the availability of VIS for EEx prediction and the optimal threshold value were determined using ROC curve analysis. The gray zone analysis of the VIS was performed by setting the false negative or positive rate R = 0.05, and the perioperative risk factors for prolonged EEx were identified by multivariate logistic analysis. The postoperative complications and outcomes were compared between different VIS groups.
RESULTS: Among the 409 patients initially screened, 379 patients were ultimately included in the study. The incidence of EEx was determined to be 112/379 (29.6%). The VIS had a good predictive value for EEx (AUC = 0.864, 95% CI: [0.828, 0.900], P < 0.001). The optimal VIS threshold for EEx prediction was 16.5, with a sensitivity of 71.54% (65.85-76.61%) and a specificity of 88.39% (81.15-93.09%). The upper and lower limits of the gray zone for the VIS were determined as (12, 17.2). The multivariate logistic analysis identified age (OR, 1.060; 95% CI: 1.017-1.106; P = 0.006), EF% (OR, 0.798; 95% CI: 0.742-0.859; P < 0.001), GFR (OR, 0.933; 95% CI: 0.906-0.961; P < 0.001), multiple valves surgery (OR, 4.587; 95% CI: 1.398-15.056; P = 0.012), and VIS > 16.5 (OR, 12.331; 95% CI: 5.015-30.318; P < 0.001) as the independent risk factors for the prolongation of EEx. The VIS ≤ 16.5 group presented a greater success rate for EEx, a shorter invasive ventilation support duration, and a lower incidence of complications than did the VIS > 16.5 group, while the incidence of reintubation was similar between the two groups.
CONCLUSIONS: In adults, after elective rheumatic heart valve surgery, the highest VIS in the immediate postoperative period was a good predictive value for EEx, with a threshold of 16.5.

UNASSIGNED: Rheumatic heart disease (RHD) is a critical problem in developing countries and is the cause of most of the cardiovascular adverse events in young people. In patients aged 50-70 years with RHD requiring mitral valve replacement (MVR), deciding between bioprosthetic and mechanical prosthetic valves remains controversial because few studies have defined the long-term outcomes.
UNASSIGNED: 1,691 Patients aged 50-70 years with RHD who received mechanical mitral valve replacement (MVRm) or bioprosthetic mitral valve replacement (MVRb) were retrospectively reviewed in Fuwai hospital from 2010 to 2014. Follow-up ended 31/12/2021; median duration was 8.0 years [interquartile range (IQR), 7.7-8.3 years]. Propensity score matching at a 1:1 ratio for 24 baseline features between MVRm and MVRb yielded 300 patient pairs. The primary late outcome was postoperative mid- to long-term all-cause mortality.
UNASSIGNED: Ten-year survival after MVR was 63.4% in the MVRm group and 63.7% in the MVRb group (HR, 0.91; 95% CI, 0.69-1.21; P = 0.528). The cumulative incidence of mitral valve reoperation was 0.0% in the MVRm group and 1.2% in the MVRb group (HR, 0.92; 95% CI, 0.69-1.21; P = 0.530). The cumulative incidence of stroke was 5.5% in the MVRm group and 6.1% in the MVRb group (HR, 0.89; 95% CI, 0.67-1.18; P = 0.430). The cumulative incidence of major bleeding events was 3.3% in the MVRm group and 3.4% in the MVRb group (HR, 0.92; 95% CI, 0.70-1.22; P = 0.560).
UNASSIGNED: In patients aged 50-70 years with RHD who underwent mitral valve replacement, there was no significant difference on survival, stroke, mitral valve reoperation and major bleeding events at 10 years. These findings suggest mechanical mitral valve replacement may be a more reasonable alternative in patients aged 50-70 years with rheumatic heart disease.

The epidemiology of valvular heart disease (VHD) has changed markedly over the last 50 years worldwide, and the prevalence and features of VHD in China are unknown. The objective of this study was to investigate the current status and etiology of VHD in China.
We used a cross-sectional national survey with stratified multistage random sampling from the general Chinese population to estimate the VHD burden. Data on demographic characteristics, medical history, physical examination, blood tests, and potential etiology were collected. Echocardiography was used to detect VHD.
The national survey enrolled 34,994 people aged 35 years or older across China. Overall, 31,499 people were included in the final analysis, and 1309 participants were diagnosed with VHD. The weighted prevalence was 3.8%, with an estimated 25 million patients in China. The prevalence of VHD increased with age and was higher in participants with hypertension or chronic kidney disease than in their counterparts. Among participants with VHD, 55.1% were rheumatic and 21.3% were degenerative. The proportion of rheumatic decreased with age, and the proportion of degenerative rose with age. However, the prevalence of rheumatic disease was still higher in the elderly population than in the younger population. Logistic regression revealed that age and hypertension were correlated with VHD.
In China, rheumatic heart disease was still the major cause of the VHD, with a significant increase in degenerative heart disease. Age and hypertension are important and easily identifiable markers of VHD.

OBJECTIVE: We aim to characterize the incidence and relative risk of rheumatic and systemic immune-related adverse effects (irAEs) among immune checkpoint inhibitor (ICI) therapy compared with those after placebo treatment.
METHODS: Randomized clinical trial studies with placebo control with the following keywords were searched from Embase, PubMed, Cochrane databases: immune checkpoint inhibitors, neoplasms, randomized controlled trials, and adverse effects.
RESULTS: Among the 5444 published and 316 registration records, nine placebo-controlled randomized clinical trials met our selection criteria, and included data from 5560 patients. Compared with placebo use, using ICIs increases the risk of overall-rheumatic irAEs. The incidence and relative risk of all-grade rheumatic irAEs were 18.40% [95% confidence interval (CI) 12.16-25.59%, p < 0.01] and 2.30 (95% CI 1.32-4.02), respectively, while musculoskeletal irAEs were 11.30% (95% CI 9.76-12.85%) and 1.01 (95% CI 0.84-1.22). The incidence and relative risk of severe rheumatic irAEs were 5.72% (95% CI 3.92-7.82%), and 8.29 (95% CI 3.75-18.35), respectively. Arthralgia was the most common rheumatic irAE (incidence 11.00%, 95% CI 9.55-12.64%; relative risk 0.99, 95% CI 0.82-1.19), although usually not severe. Colitis (incidence 3.23%, 95% CI 1.27-7.98%; relative risk 6.53, 95% CI 2.66-16.04) and pneumonitis (incidence 3.11%, 95% CI 1.56-6.21; relative risk 4.04, 95% CI 1.65-9.89) were commonly observed and tended to be severe. Hepatitis, hypophysitis, thyroiditis, and myositis were rare and less recorded, yet can be severe and life threatening. Other extremely rare severe rheumatic irAEs included sarcoidosis (n = 11), autoimmune arthritis (n = 8), autoimmune uveitis (n = 3), autoimmune pericarditis, bursitis, osteochondrosis, psoriasis, polymyalgia rheumatica, systemic inflammatory response syndrome, and Sjögren syndrome (n = 1, each).
CONCLUSIONS: ICI therapy increased the incidence and relative risk of all-grade and severe rheumatic irAEs. Arthralgia was the most commonly observed non-severe irAE, while colitis and pneumonitis were commonly observed severe irAEs. Rare rheumatic irAEs like hepatitis, hypophysitis, thyroiditis, and myositis warrant special attention.

UNASSIGNED: We compared and analyzed differences between repair vs. replacement of mitral valves on severe rheumatic mitral stenosis by looking at mid-term clinical outcomes.
UNASSIGNED: Patients with severe rheumatic mitral stenosis (mitral valve area ≤1.5 cm2, with or without mitral valve regurgitation) from January 2011 to September 2017 were divided into two groups: a mitral valve repair group (MVP) and a mitral valve replacement group (MVR). After propensity score matching between the two groups, we compared changes in post-operation clinical outcomes. We also monitored changes in left ventricular longitudinal and circumferential strain in successfully matched patients (20 pairs) by echocardiography speckle tracing.
UNASSIGNED: A total of 921 patients were recruited (221 in MVP and 700 in MVR). After a propensity score matching, 216 cases were selected with 108 patients in each group. With a follow-up period of 3 months to 7.1 years, the incidence of heart failure was observed to be significantly higher in the MVR group than in the MVP group (P<0.05). Echocardiographic speckle tracking imaging analysis showed that left ventricular longitudinal strain decreased in the MVR group, suggesting that a change of cardiac structure may affect the cardiac function.
UNASSIGNED: Selecting suitable patients for mitral valve repair is feasible even for patients with severe rheumatic mitral stenosis. In our study, compared with prosthetic valve replacement in these patients, valve repair still significantly reduced the valve-related complications rates and improved the quality of life during the follow-up.

UNASSIGNED: We aimed to assess the pathological characteristics of rheumatic mitral valve disease in Chinese patients and formulate a pathological grading system to identify cases suitable for rheumatic mitral valve repair (rMVP).
UNASSIGNED: Nearly 5 years of follow-up data on patients who underwent rMVP were analysed. A Kaplan-Meier survival curve for freedom from reoperation and valve failure was constructed. A pathological grading system of rheumatic mitral valve lesions (PGSRMVL) was developed based on the pathological characteristics of rheumatic mitral valve disease and tested by receiver operating characteristics (ROCs) curve analysis. Predictors of endpoints for rheumatic repair were analysed.
UNASSIGNED: From January 2012 to June 2016, 179 patients underwent rMVP in our centre. The mean follow-up duration was 24±14 months. A left atrial anterior and posterior diameter >60 mm was an independent predictor for the 16 endpoints [hazard ratio (HR) =3.884, P=0.029]. Between 2015 and 2016, 126 consecutive pathological characteristics of rheumatic mitral valve were evaluated (61 and 65 repair and replacement cases, respectively). The ROCs area under the curve was 0.891 for the correlation between the pathological score and successful repair (cut-off point, 17.5; sensitivity, 78%; specificity, 85.2%). Seven lesions had higher ratios in the replacement group than the repair group. Commissural fusion/calcification and main chordae tendineae fusion/calcification were the most common severe pathological lesions.
UNASSIGNED: The main pathological characteristics of rheumatic mitral valve disease in Chinese patients are commissure and sub-valvular apparatus lesions. Most patients can be appropriately treated via commissurotomy and leaflet thinning. Severe calcification of the commissure and sub-valvular apparatus can considerably decrease the odds of a successful repair. The median follow-up results of rheumatic mitral repair are considered satisfactory for the pathological characteristics in Chinese patients.
