[PMID: 39390480 PMCID: PMC11465527 DOI: 10.1186/s12893-024-02608-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2024] [Accepted: 10/01/2024] [Indexed: 10/12/2024] Open
Abstract
OBJECTIVE The aim of this study was to investigate sex-related differences in the clinical characteristics and hospital outcomes of patients undergoing surgery for acute type A aortic dissection (AAAD). METHODS This study was a retrospective study. Patients who underwent surgery for AAAD at the Department of Cardiac Surgery, Fujian Medical University Union Hospital, from January 2014 to March 2023 were consecutively included. Data was extracted from electronic medical records. The primary outcome measure was in-hospital mortality, and secondary outcome measures included new-onset postoperative arrhythmia (POA), acute kidney injury (AKI), hepatic dysfunction, neurological complications, gastrointestinal hemorrhage, ICU length of stay, and hospital length of stay. Patients were divided into two groups based on sex, and data analysis was performed using SPSS 25.0 software. RESULTS A total of 1137 subjects were included, with 863 males (75.9%) and 274 females (24.1%). There were statistically significant differences in age and BMI between the two groups (P < 0.05). There was no statistically significant difference in the incidence of pain at the onset between the two groups, but chest tightness in females was higher than in males (22.6% vs. 13.8%). Regarding primary outcomes, the in-hospital mortality rate was 11.1% for males and 10.6% for females (P = 0.803). There were no statistically significant differences between the groups in ICU days, length of hospitalization, neurological complications, or liver dysfunction (P > 0.05). The rate of POA in females was 4.7%, higher than in males (2.2%), but AKI and gastrointestinal hemorrhage were both higher in males than in females (P < 0.05). Multivariate analysis showed that age, white blood cell (WBC) counts, lactic acid, operation duration and prolonged mechanical ventilation (PMV) increased the risk of in-hospital mortality in male patients. Hypertension, WBC counts, lactic acid, and PMV increased the risk of in-hospital mortality in female patients. CONCLUSION Despite significant baseline characteristic differences between male and female AAAD patients, there were no significant differences in onset symptoms. The in-hospital mortality rates were similar between male and female patients, but the risk factors for in-hospital mortality differed.

Abstract
OBJECTIVES Gender difference in the outcome after type A aortic dissection (TAAD) surgery remains an issue of ongoing debate. In this study, we aimed to evaluate the impact of gender on the short- and long-term outcome after surgery for TAAD. METHODS A multicentre European registry retrospectively included all consecutive TAAD surgery patients between 2005 and 2021 from 18 hospitals across 8 European countries. Early and late mortality, and cumulative incidence of aortic reoperation were compared between genders. RESULTS A total of 3902 patients underwent TAAD surgery, with 1185 (30.4%) being females. After propensity score matching, 766 pairs of males and females were compared. No statistical differences were detected in the early postoperative outcome between genders. Ten-year survival was comparable between genders (47.8% vs 47.1%; log-rank test, P = 0.679), as well as cumulative incidences of distal or proximal aortic reoperations. Ten-year relative survival compared to country-, year-, age- and sex-matched general population was higher among males (0.65) compared to females (0.58). The time-period subanalysis revealed advancements in surgical techniques in both genders over the years. However, an increase in stroke was observed over time for both populations, particularly among females. CONCLUSIONS The past 16 years have witnessed marked advancements in surgical techniques for TAAD in both males and females, achieving comparable early and late mortality rates. Despite these findings, late relative survival was still in favour of males.

ADVANCES 2024; 3:100909. [PMID: 38939657 PMCID: PMC11198187 DOI: 10.1016/j.jacadv.2024.100909] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 12/18/2023] [Accepted: 01/24/2024] [Indexed: 06/29/2024]
Abstract
Background There is controversy regarding sex differences in short-term mortality in acute type A aortic dissection (ATAAD). Objectives This study aimed to investigate the impact of sex differences on 30-day operative mortality after ATAAD surgery and to determine if other covariates modify the association. Methods Consecutive patients (N = 5670) with surgically repaired ATAAD were identified from the multicenter China 5A study. The primary outcome was operative mortality. The age dependency was modeled using a cubic spline curve. Results There were 1,503 females (26.5%) and 4,167 males (73.5%). Females were older and had a lower percentage of comorbidities compared with males. Females had higher mortality compared to males (10.2% vs 8.2%, P = 0.019); however, there was no difference after propensity analyses (adjusted OR: 1.334 [95% CI: 0.918-1.938]). There was an interaction with sex and age (P interaction = 0.035): older age was associated with higher odds of operative mortality among females (OR: 1.045 [95% CI: 1.029-1.061]) compared with males (OR: 1.025 [95% CI: 1.016-1.035]). The risk of mortality for males and females appears to diverge at 55 years of age (P interaction = 0.019): females under 55 years of age had similar odds to males (OR: 0.852 [95% CI: 0.603-1.205]) but higher odds when over 55 years (OR: 1.420 [95% CI: 1.096-1.839]) compared to males. Conclusions Under the age of 55 years, females have similar odds of operative mortality compared with males; however, over the age of 55 years females have higher odds than males. Understanding differences in risk allows for individualized treatment strategies. (Additive Anti-inflammatory Action for Aortopathy & Arteriopathy; NCT04398992).

Abstract
OBJECTIVES Current guidelines recommend that enteral nutrition (EN) be implemented as early as possible in patients after cardiopulmonary bypass (CPB), but the optimal time to initiate EN remains controversial. Therefore, the aim of this study was to investigate the effect of timing of EN initiation on poor prognosis in patients after CPB. METHODS This was a prospective observational study with patients who underwent CPB in a tertiary hospital from September 1, 2021, to January 31, 2022. The patients were divided into three groups according to the timing of EN initiation: <24 h, 24 to 48 h, and >48 h. Unconditional logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals to identify independent risk factors for poor prognosis. RESULTS The study included 579 patients, of whom 255 patients had EN initiated at <24 h (44%), 226 at 24 to 48 h (39%), and at >48 h (17%). With EN <24 h as a reference, multivariate logistic analysis showed that EN 24 to 48 h (OR, 1.854, P = 0.008) and EN >48 h (OR, 7.486, P <0.001) were independent risk factors for poor prognosis after CPB. Age (OR, 1.032, P = 0.001), emergency surgery (OR, 10.051; P <0.001), surgical time (OR, 1.006; P <0.001), and sequential organ failure assessment score (OR, 1.269; P = 0.001) also increased the risk for poor prognosis after CPB. CONCLUSIONS Compared with early EN <24 h, EN 24 to 48 h and EN >48 h increased the risk for poor prognosis in patients after CPB.

Abstract
Disparities in outcomes for patients with cardiovascular disease and those undergoing cardiac or vascular operations are well-established. These disparities often span several dimensions and persist despite advancements in medical and surgical care; sex is among the most pervasive. Specifically, females sex has been implicated as a predictor of poor outcomes in both patients with acute type A aortic dissections (ATAADs) and type B aortic dissections (TBADs). For instance, one study, using the International Registry of Acute Aortic Dissection database, found that females with acute aortic dissection-including ATAAD and TBAD that were either medically or surgically managed-had 40% higher odds of in-hospital mortality than men. Notably, both types of acute aortic dissections affect men more commonly than females and can be life-threatening without prompt, appropriate treatment. The underlying mechanisms for these disparities are unclear but are thought to be multifactorial. The association of sex with patterns of disease and outcomes in patients with ATAAD or TBAD remains unclear, with conflicting reports from different studies. Thus, we sought to review the literature regarding sex disparities in patients with ATAAD and TBAD.

Does deep hypothermic circulatory arrest with versus without retrograde cerebral perfusion affect the outcomes after proximal aortic arch aneurysm and acute type A aortic dissection repair? Different pathologies and cerebral protection techniques with similar results. J Card Surg 2022; 37:3287-3289.

Abstract
Hypothermic circulatory arrest is used for proximal and total aortic arch correction in patients with aortic arch aneurysm and acute or chronic type A aortic dissection. Different cerebral perfusion techniques have been proposed for reducing morbidity and mortality rate. The study of Arnaoutakis et al. showed that deep hypothermic circulatory arrest with or without retrograde cerebral perfusion for proximal aortic aneurysm and acute type A aortic dissection correction had similar results with regard to morbidity and mortality rate. In addition, the short circulatory arrest time contributes for favorable outcomes of these patients. Although antegrade cerebral perfusion with hypothermic circulatory is widely used by many cardiac surgeons, deep hypothermic circulatory arrest with or without retrograde cerebral perfusion remains an alternative and safe method for brain protection in patients undergoing proximal aortic arch aneurysm or acute type A aortic dissection repair.
