Methods: This study retrospectively analysed the clinical data of 203 patients with chronic heart failure at Xingtai Third Hospital from January 2019 to January 2022. In accordance with different intervention programs, the patients were divided into a study group (SG, n = 102) and a reference group (RG, n = 101). The SG received the extended intervention model based on case management, and the RG adopted the conventional intervention model. Comparison was conducted on the treatment compliance, cardiac function, activity of daily living scale (ADL) scores and readmission rates in both groups. Results: After intervention, the SG showed higher treatment compliance (p < 0.05), lower heart rate, higher left ventricular ejection fraction, ratio of transmitral peak rapid filling velocity to transmitral peak atrial filling velocity at mitral orifice and six-minute walk distance (p < 0.001) and significantly lower ADL score and readmission rates than the RG (p < 0.05). Conclusion: The extended intervention model based on case management positively influences the treatment compliance of patients with chronic heart failure and continuously improves patients' cardiac function, reduces the readmission rate, enhances daily living ability, comprehensively increases clinical efficacy and benefits patients for a long period.","PeriodicalId":257138,"journal":{"name":"The heart surgery forum","volume":"95 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139003888","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}

We investigated statewide readmissions, costs, and outcomes associated with the surgical management of type A aortic dissection repairs at low- and high-volume centers. Methods: We identified all adult type A aortic dissection patients who underwent operative repair in the Maryland Health Services Cost Review Commission's database (2012–2020). Hospitals were stratified into high- (top quartile of total repairs) or low-volume centers. Results: Of the 249 patients included, 193 (77.5%) were treated at a high-volume center. Patients treated at high- and low-volume centers had no differences in age, sex, race, primary payer, or severity (all p > 0.5). High- compared to low-volume centers had a greater proportion of patients transferred in (71.5% vs. 17.9%, p < 0.001). High-volume centers also had longer lengths of stay (12 vs. 8 days, p < 0.001), similar inpatient mortality (13.0% vs. 16.1%, p = 0.6), and similar proportion of patients readmitted (54.9% vs. 51.8%, p = 0.7). High-volume centers had greater index admission costs ($114,859 vs. $72,090, p < 0.001) and similar readmission costs ($48,367 vs. $42,204, p = 0.5). At high-volume centers, transferred patients compared to direct admissions had greater severity of illness (p = 0.05), similar mortality (p = 0.53), and greater lengths of stay (p = 0.05).

Predicting which patients are at risk for readmission may guide patient management prior to discharge. Methods: The National Readmissions Database was utilized to identify patients treated for ATAAD between 2010 and 2018. Univariate mixed effects logistic regression was used to assess each variable. Variables were assigned risk points based off the bootstrapped (bias-corrected) odds ratio of the final variable model according to the Johnson's scoring system. A mixed effect logistic regression was run on the risk score (sum of risk points) and 30-day readmission. Calibration plots and predicted readmission curves were generated for model assessment. Results: A total of 30,727 type A aortic dissections were identified. The majority of ATAAD (66%) were in men with a median age of 61 years and 30-day readmission rate of 19.4%. The risk scores ranging from –1 to 14 mapped to readmission probabilities between 3.5% and 29% for ATAAD. The predictive model showed good calibration and receiver operator characteristics with an area under the curve (AUC) of 0.81.

This study is to review the outcomes of adult cardiac surgery between males and females in a Saudi tertiary referral hospital. Method: This was a retrospective study for 925 adult patients operated on for ischemic coronary artery disease and acquired aortic and mitral valvular heart disease from 2015 to August 2023. We analyzed patient characteristics, intraoperative data, and postoperative results to compare outcomes between males and females. Results: Preoperative risk factors were not significantly different in both groups. Postoperative outcomes showed gender-based differences. In univariable analysis, females, compared to males, had significantly greater odds of prolonged postoperative ventilation (>24 hours), 32.8% of females compared to 20.7% of males (p < 0.001). Also, sternal wound infection was notably higher among females (13.3%) (p < 0.001). Mortality also exhibited a significant association, with 14.2% of females experiencing mortality compared to 9.4% of males (p = 0.049). In the multivariable analysis for elevated postoperative troponin, the use of pre-operative intra-aortic balloon pump, urgent/emergent surgery, elevated pre-operative troponin and combined bypass grafting with valve surgery, were also predictive of higher post-operative troponin concentrations (beta = 0.43, 95% CI: 0.25 to 0.62, p < 0.001). Conclusion: Females in Saudi Arabia have an increased risk of short-term morbidity and mortality after cardiac surgery compared to males. Vague and delayed presentation and then the late diagnosis and referral are likely the main contributing factors. This highlights the need to implement preoperative measures to improve early diagnosis and referral to eliminate gender bias.","PeriodicalId":257138,"journal":{"name":"The heart surgery forum","volume":"63 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139003181","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}

The infants were divided into survival group (n = 11) and non-survival group (n = 17) according to 30-day survival after discharge from hospital.

We aimed to investigate the impact of serum uric acid level (UA) on the POAF of patients undergoing coronary artery bypass grafting (CABG). METHODS A retrospective cohort study of patients undergoing CABG at the Hospital between January 2019 and December 2019 was performed. Hyperuricemia (HUA) was defined as serum UA levels >420 µmol/l in men and>360 µmol/l in women. The included patients were divided into the HUA group (103) and the normal UA group (306) based on serum uric acid levels before surgery. POAF was defined as atrial fibrillation that occurred within 7 days of cardiac surgery. We use COX regression analysis and Kaplan-Meier curves (log-rank test) for statistical analysis. RESULTS The incidence of HUA was 25.2% (103/409). The rate of POAF was 28.61%. Univariate COX regression analysis showed the risk of POAF occurrence. It was revealed that UA was an independent predictor of POAF (HR=1.493, 95% CI1.007-2.212, P = 0.046). Kaplan-Meier curves showed that high serum UA was associated with the occurrence of POAF (P = 0.034). Moreover, age (HR=1.05, 95%CI 1.024-1.076, P < 0.001), AD (HR=1.567, 95%CI .015-2.42, P = 0.043), and CCB (HR=0.647, 95%CI 0.424-0.988, P = 0.044) also were independent predictors of POAF.
