Objective: The aim of this study was to investigate the efficacy and safety of tolvaptan, as well as the impact of its treatment dose and duration in heart failure patients with congestive signs. Methods: The PubMed, Embase, Cochrane Library, and ClinicalTrials.gov databases were searched to collect data from all randomized controlled trials (RCT) examining the efficacy and safety of tolvaptan in heart failure patients with congestive signs compared with placebo or blank control until March 4, 2021. Urine volume, change in body weight, improvement in dyspnea, and reduction of edema were evaluated as efficacy indicators. All-cause mortality, worsening heart failure, and adverse events were considered safety indicators. The quality of eligible publications was assessed using the Cochrane risk of bias for RCTs. Results: Ten RCTs with 5,980 patients were included in this analysis. Compared with control, tolvaptan significantly reduced weight in the short term (day 1, 7 RCTs, weighted mean difference (WMD): –1.09, 95% confidence interval (CI): –1.27 to –0.91; day 2, 2 RCTs, WMD: –1.67, 95% CI: –3.00 to –0.33; day 7, 4 RCTs, WMD: –0.95, 95% CI: –1.25 to –0.66), increased urine volume (WMD: 1,825.72, 95% CI: 1,438.38–2,213.07), and relieved dyspnea (risk ratio (RR): 1.12, 95% CI: 1.05–1.19) without increasing the mortality rate (RR: 0.96, 95% CI: 0.87–1.06). Furthermore, the weight loss and increase in urine volume were not dose-dependent effects, and prolonged medication did not lead to sustained weight loss. In addition, there seemed to be more adverse events (RR: 1.17, 95% CI: 1.03–1.32) after treatment with tolvaptan. Further analysis revealed that patients treated with tolvaptan were more likely to report thirst (RR: 6.09, 95% CI: 3.37–11.00) and dry mouth (RR: 6.36, 95% CI: 4.09–9.90), as well as develop hypernatremia (RR: 12.76, 95% CI: 3.52–46.32). Conclusions: The meta-analysis shows that tolvaptan can improve congestion with no increase in mortality rate, but should be used to guard against adverse events. Deserve to be mentioned, the number of RCTs included was limited, suggesting that the observed results should be interpreted with caution. Additional robust clinical studies are warranted to validate the present findings.

Objective: This study aimed to evaluate the major adverse cardiovascular and cerebrovascular events (MACCEs) and overall safety profile associated with iodixanol in Chinese patients undergoing percutaneous coronary intervention (PCI). Methods: Patients at 30 centers in China registered in the OpenClinic v3.6 database from October 30, 2013, to October 7, 2015, were included in the study. The primary endpoint was in-hospital MACCEs including target lesion revascularization (TLR), stroke, stent thrombosis, cardiac death, and PCI-related myocardial infarction (MI) within 72 h post-PCI. Secondary endpoints were MACCEs from 72 h to 30 d post-PCI and other safety events within 30 d post-PCI. Results: A total of 3,042 patients were enrolled. The incidence of MACCEs within 72 h post-PCI was 2.33% (n = 71), including cardiac death (0.03%, n = 1) and PCI-related MI (2.30%, n = 70). The incidence of MACCEs from 72 h to 30 d post-PCI was 0.16% (n = 5), including cardiac death (0.10%, n = 3), PCI-related MI (0.03%, n = 1), and TLR for stent thrombosis (0.03%, n = 1). The incidence of composite angiographic or procedural complications was 2.86% (n = 87); 233 (7.86%) patients had results suggesting contrast-induced acute kidney injury. Conclusions: These findings indicate that the use of iodixanol in Chinese patients undergoing PCI is associated with a low incidence of MACCEs, confirming its safety in this population.

The outcomes of patients with myocardial infarction (MI) have substantially improved given the rapid progress that has occurred in revascularization techniques and secondary prevention, and the majority of MI patients subsequently enter a chronic stable phase. Therefore, the long-term management of patients with MI has become a core issue in daily clinical practice for cardiologists. The long-term incidence of adverse events can be further reduced using newly developed medications and therapies ranging from lipid-lowering agents (eg, proprotein convertase subtilisin/kexin type 9 inhibitors) to anti-thrombotic treatments (eg, shortened dual anti-platelet therapy). However, a considerable number of patients still experience adverse events, as some residual risk can remain despite intensive secondary prevention, such as continuously elevated cholesterol levels, chronic cardiovascular inflammation, and rapid atherosclerosis progression due to increased plaque instability. Therefore, the present review sought to summarize and discuss recent advances in several key aspects regarding the long-term management of MI patients, with the expectation of clarifying the available treatment strategies for various clinical scenarios, examining the gaps between trial evidence and clinical practice, and providing possible directions for future research.

Objective: While evidence-based clinical guidelines recommend chordal-sparing mitral valve replacement, rather than mitral valve repair, in patients with severe ischemic mitral regurgitation (IMR) undergoing coronary artery bypass grafting, there are no similar recommendations for patients undergoing left ventricular reconstruction (LVR). This study aimed to compare the clinical outcomes of mitral valve repair and replacement in patients undergoing LVR complicated by more than moderate IMR. Methods: In this single-center cohort study, a total of 74 consecutive patients who underwent LVR and mitral valve surgery (repair group: 59; replacement group: 15), during the period from March 2000 to March 2021 at Fuwai Hospital (Beijing, China) were retrospectively enrolled. Survival rates were calculated with the Kaplan-Meier method and compared using the log-rank test. Univariate Cox analysis was performed to evaluate possible confounders, followed by adjustment in multivariate analysis. The primary outcome was survival free of major adverse cardiovascular and cerebrovascular events (MACCE). Results: Median follow-up time was 59.4 months. Compared with mitral valve replacement, mitral valve repair was associated with increased risk of perioperative use of ventricular assist device (22.0% vs. 0, P = 0.045). There was no difference in overall survival (hazard ratio (HR), 1.10; 95% confidence interval (CI), 0.31–3.93; Plogrank = 0.888) and MACCE-free survival (HR, 1.54; 95% CI, 0.65–3.65; Plogrank = 0.319), even after multivariate Cox regression (HR, 1.35; 95% CI, 0.37–4.88; PCox = 0.646; and HR, 1.41; 95% CI, 0.57–3.44; PCox = 0.455, respectively). Furthermore, while no differences were observed in ejection fraction and left ventricular end-diastolic diameter on follow-up echocardiography, mitral valve repair was associated with an increased risk of recurrent mitral regurgitation (P = 0.041). Conclusions: In patients undergoing LVR complicated by more than moderate IMR, both concomitant mitral valve repair and replacement can be successfully achieved with comparable overall and MACCE-free survival outcomes; however, mitral valve replacement may be superior to mitral valve repair for persistent correction of mitral dysfunction.

Objective: Annulus-sparing (AS) repair for tetralogy of Fallot (TOF) with a dysplastic pulmonary valve annulus (PVA) is a challenging procedure and is controversial. This study aimed to assess the feasibility and surgical effect of AS repair versus transannular patch enlargement (TAPE) repair, especially in individuals with dysplastic pulmonary valves. Methods: This retrospective cohort study included 375 pediatric patients with a primary diagnosis of TOF in the Center for Pediatric Cardiac Surgery of Fuwai hospital from January 2014 to June 2017. Among them, 60 consecutive and nonselective patients underwent 1-stage repair of TOF with aggressive PVA-preserving strategies performed by a single surgeon were enrolled in AS cohort. In AS cohort, patients were divided into AS, PVA z-score ≥−2 group (33 patients) and AS, PVA z-score <−2 group (27 patients). During the same period, 315 patients underwent TAPE repair by other surgeons were enrolled as TAPE cohort, of these, 87 patients with PVA z-score ≥−2 were excluded. From the 228 patients in the TAPE group, 27 cases were selected as TAPE, PVA z-score <−2 group according to the propensity score and 1:1 ratio with AS, PVA z-score <−2 group. The primary outcome was a composite of reintervention, significant pulmonary regurgitation, and significant annular peak gradient (APG). Kaplan-Meier curve was plotted to show the survival rate of severe pulmonary regurgitation. Results: One death occurred after the TAPE operation in TAPE group, and 1 patient in the AS z ≥−2 group needed reintervention with a balloon. After a median follow-up of (30.3 ± 11.6) months, compared with AS z ≥−2 group, there was no difference in the technical performance score for severe pulmonary stenosis (APGs > 20 mmHg) in the AS z <−2 group. Compared with TAPE, AS repair was often accompanied by a postoperative APGs over 20 mmHg (P = 0.001). More patients underwent TAPE suffered from moderate or severe pulmonary regurgitation than those who received AS repair (20 (74.1%) vs. 7 (26.0%), P < 0.001). AS repair was associated with a shorter duration of mechanical ventilation (20 vs. 29 hours, P = 0.039), faster discharge from the intensive care unit (2.0 vs. 4.0 days, P = 0.022) and shorter postoperative hospitalization (8.0 vs. 11.0 days, P = 0.008) compared with TAPE. Conclusions: APG demonstrated an upward trend in the TAPE group and a downtrend in the AS group after discharge from hospital. AS repair had an acceptable surgical effect in TOF patients, even in those with a dysplastic PVA. A higher APG remained upon hospital discharge in dysplastic patients with AS, but a downward trend was observed over time.

In AS cohort, patients were divided into AS, PVA z-score ≥−2 group (33 patients) and AS, PVA z-score <−2 group (27 patients). During the same period, 315 patients underwent TAPE repair by other surgeons were enrolled as TAPE cohort, of these, 87 patients with PVA z-score ≥−2 were excluded. From the 228 patients in the TAPE group, 27 cases were selected as TAPE, PVA z-score <−2 group according to the propensity score and 1:1 ratio with AS, PVA z-score <−2 group. The primary outcome was a composite of reintervention, significant pulmonary regurgitation, and significant annular peak gradient (APG). Kaplan-Meier curve was plotted to show the survival rate of severe pulmonary regurgitation. Results: One death occurred after the TAPE operation in TAPE group, and 1 patient in the AS z ≥−2 group needed reintervention with a balloon. After a median follow-up of (30.3 ± 11.6) months, compared with AS z ≥−2 group, there was no difference in the technical performance score for severe pulmonary stenosis (APGs > 20 mmHg) in the AS z <−2 group. Compared with TAPE, AS repair was often accompanied by a postoperative APGs over 20 mmHg (P = 0.001). More patients underwent TAPE suffered from moderate or severe pulmonary regurgitation than those who received AS repair (20 (74.1%) vs. 7 (26.0%), P < 0.001). AS repair was associated with a shorter duration of mechanical ventilation (20 vs. 29 hours, P = 0.039), faster discharge from the intensive care unit (2.0 vs. 4.0 days, P = 0.022) and shorter postoperative hospitalization (8.0 vs. 11.0 days, P = 0.008) compared with TAPE. Conclusions: APG demonstrated an upward trend in the TAPE group and a downtrend in the AS group after discharge from hospital. AS repair had an acceptable surgical effect in TOF patients, even in those with a dysplastic PVA. A higher APG remained upon hospital discharge in dysplastic patients with AS, but a downward trend was observed over time.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43036822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
