Abstract
INTRODUCTION Cardiovascular diseases are a class of heart and blood vessel-related illnesses. In Sub-Saharan Africa, including Ethiopia, preventable heart disease continues to be a significant factor, contrasting with its presence in developed nations. Therefore, the objective of the study was to assess the prevalence of death due to cardiac disease and its risk factors among heart patients in Ethiopia. METHODS The current investigation included all cardiac patients who had cardiac surgery in the country between 2012 and 2023. A total of 1520 individuals were participated in the study. Data collection took place between February 2022 and January 2023. The study design was a retrospective cohort since the study track back patients' chart since 2012. Machine learning algorithms were applied for data analysis. For machine learning algorithms comparison, lift and AUC was applied. RESULTS From all possible algorithms, logistic algorithm at 90%/10% was the best fit since it produces the maximum AUC value. In addition, based on the lift value of 3.33, it can be concluded that the logistic regression algorithm was performing well and providing substantial improvement over random selection. From the logistic regression machine learning algorithms, age, saturated oxygen, ejection fraction, duration of cardiac center stays after surgery, waiting time to surgery, hemoglobin, and creatinine were significant predictors of death. CONCLUSION Some of the predictors for the death of cardiac disease patients are identified as such special attention should be given to aged patients, for patients waiting for long periods of time to get surgery, lower saturated oxygen, higher creatinine value, lower ejection fraction and for patients with lower hemoglobin values.

Abstract
INTRODUCTION Living in poverty, especially in low-income countries, are more affected by cardiovascular disease. Unlike the developed countries, it remains a significant cause of preventable heart disease in the Sub-Saharan region, including Ethiopia. According to the Ethiopian Ministry of Health statement, around 40,000 cardiac patients have been waiting for surgery in Ethiopia since September 2020. There is insufficient information about long-term cardiac patients' post-survival after cardiac surgery in Ethiopia. Therefore, the main objective of the current study was to determine the long-term post-cardiac surgery patients' survival status in Ethiopia. METHODS All patients attended from 2012 to 2023 throughout the country were included in the current study. The total number of participants was 1520 heart disease patients. The data collection procedure was conducted from February 2022- January 2023. Machine learning algorithms were applied. Gompertz regression was used also for the multivariable analysis report. RESULTS From possible machine learning models, random survival forest were preferred. It emphasizes, the most important variable for clinical prediction was SPO2, Age, time to surgery waiting time, and creatinine value and it accounts, 42.55%, 25.17%,11.82%, and 12.19% respectively. From the Gompertz regression, lower saturated oxygen, higher age, lower ejection fraction, short period of cardiac center stays after surgery, prolonged waiting time to surgery, and creating value were statistically significant predictors of death outcome for post-cardiac surgery patients' survival in Ethiopia. CONCLUSION Some of the risk factors for the death of post-cardiac surgery patients are identified in the current investigation. Particular attention should be given to patients with prolonged waiting times and aged patients. Since there were only two fully active cardiac centers in Ethiopia it is far from an adequate number of centers for more than 120 million population, therefore, the study highly recommended to increase the number of cardiac centers that serve as cardiac surgery in Ethiopia.

Trends in Isolated Mitral Valve Repair or Replacement Surgery in Australia: A Statewide Cohort Linkage Study. Heart Lung Circ 2024; 33:120-129. [PMID: 38160129 DOI: 10.1016/j.hlc.2023.11.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 11/28/2023] [Accepted: 11/30/2023] [Indexed: 01/03/2024]
Abstract
BACKGROUND Global trends in mitral valve surgery (MVSx) suggest increasing repair compared with replacement, especially in the United States and European countries. The relative use, and outcomes of, MV repair and replacement in Australia are unknown. METHODS New South Wales residents who underwent isolated MVSx between 2001 and 2017 were identified from the Admitted-Patient-Data-Collection database. Mortality outcomes were tracked to 31 Dec 2018 and adjusted based on age, sex, urgency of operation, and comorbidity status. RESULTS The study cohort comprised 5,693 patients: 2020 (35%) underwent repair (MVr), 1,656 (29%) underwent mechanical replacement (mech.MVR), and 2017 (35%) underwent bioprosthetic replacement (bio.MVR). Respective median ages [interquartile range] were 67 yo [59-75 yo], 64 yo [55-71 yo], and 75 yo [68-80 yo] (p<0.001 across groups). Between 2001 and 2017, total MVSx increased steadily with population growth. Whereas the relative use of MVr remained static (34% to 38%), that for bio.MVR (22% to 50%) and mech.MVR (45% to 13%) changed significantly. MVr had the best outcome with 1.2% in-hospital, 2.5% 1-year, and 21.6% total cumulative mortality during a median follow-up of 6.5 years. Compared to MVr, the adjusted hazard ratio (aHR) for mech.MVR and bio.MVR for long-term mortality were 1.41 (95% confidence interval [CI]=1.24-1.61) and 1.73 (95% CI=1.53-1.95), respectively. Heart failure and sepsis were the main cardiovascular and noncardiovascular causes of death in all groups. CONCLUSION In this statewide Australian cohort examined over 17 years, MVr is potentially underutilised despite having superior outcomes to MVR. Access to quality dataset which provides the indication for MVSx and quantitative clinical factors is critical to further improve MVr coverage and outcome MVSx.

Abstract
Background Paravalvular leak (PVL) following valve replacement is a serious cardiovascular complication that increases morbidity and mortality. Valve replacement with the interrupted suture technique using polyester suture provides adequate tensile strength and reduces the probability of tissue reaction. This study compared the clinical equivalence of Trubond®(Healthium) and Ethibond® (Ethicon, Johnson & Johnson) braided polyester sutures for valvular prosthesis fixation using interrupted suturing, with respect to the proportion of subjects having PVL after aortic valve (AV) or mitral valve (MV) replacement. Methodology Patients undergoing AV/MV replacement were enrolled and randomized in this study. The primary endpoint of this prospective, multicentric, two-arm, randomized (1:1), parallel-group, single-blind study (December 2020-October 2022) was the presence of PVL in Trubond® (n = 40) and Ethibond® (n = 42) groups within 26 weeks of surgery. The secondary endpoints included event rate of all-cause mortality, cardiac death, stroke, myocardial infarction, re-hospitalization, re-intervention, wound infection, operative time, intraoperative suture parameters, postoperative hospital stay, time to resume normal activities and work, quality of life, patient satisfaction, and adverse events in both groups. Results Patients who underwent AV/MV replacement and were followed up until 26 weeks had no incidence of PVL or other postoperative complications. No requirement for readmission or re-intervention was noted in both groups. Intraoperative suture handling characteristics, operative time, and hospital stay were also comparable between the groups. With each follow-up, subjects in both groups exhibited improved postoperative functional abilities, quality of life, and health status. Conclusions Trubond® braided polyester suture is clinically equivalent to Ethibond® braided polyester suture. Trubond® suture is safe and effective for valvular prosthesis fixation in patients undergoing AV or MV replacement.

Abstract
OBJECTIVE The aim of this study was to investigate the efficacy of vasoactive inotrope score at the 24th postoperative hour for mortality and morbidity in elective adult cardiac surgery. METHODS Consecutive patients who underwent elective adult coronary artery bypass and valve surgery in a single tertiary center for cardiac surgery between December 2021 and March 2022 were prospectively included. The vasoactive inotrope score was calculated with the dosage of inotropes that were continuing at the 24th postoperative hour. Poor outcome was defined as any event of perioperative mortality or morbidity. RESULTS The study included 287 patients, of whom 69 (24.0%) were on inotropes at the 24th postoperative hour. The vasoactive inotrope score was higher (21.6±22.5 vs. 0.94±2.7, p=0.001) in patients with poor outcome. One unit increase in the vasoactive inotrope score had an odds ratio of 1.24 (95% confidence interval: 1.14-1.35) for poor outcome. The receiver operating characteristic curve of vasoactive inotrope score for poor outcome had an area under the curve of 0.857. CONCLUSION Vasoactive inotrope score at the 24th hour can be a very valuable parameter for risk calculation in the early postoperative period.

[PMID: 36647496 PMCID: PMC9840041 DOI: 10.21037/jtd-22-1345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Accepted: 11/24/2022] [Indexed: 12/15/2022]
Abstract
Background Left ventricular ejection fraction (LVEF) is an indicator of heart failure, and it is controversial whether patients with reduced preoperative left ventricular ejection fraction can benefit from heart valve surgery. We aimed to assess the differences in clinical characteristics after surgery in patients with different grades of reduced preoperative LVEF to guide clinical management. Methods A total of 100 heart valve disease patients with low LVEF (≤50%) who had undergone valve surgery in the Department of Cardiology. The patients were divided into three groups according to their LVEF measured by echocardiography before surgery, with LVEF ≤40% as group A, 40%< LVEF ≤45% as group B, and 45%< LVEF ≤50% as group C. Clinical characteristics such as postoperative LVEF values, oxygenation index, liver function and inflammatory index, intra-aortic balloon pump (IABP) utilization rate, and mortality were compared among the three groups of patients. Results There was no statistically significant difference in the preoperative baseline data between the three groups of patients (P>0.05). The clinical outcomes of patients in group A (n=28) were similar to those of patients in groups B (n=39) and C (n=33) (P>0.05). The vasoactive-inotropic score (VIS), postoperative ventilator use time, length of stay in the care unit, IABP use rate, and mortality rate on the first postoperative day were higher in group A. By comparing the preoperative and postoperative (within 48 hours and 3 months after surgery) cardiac echocardiograms of the three groups, we learned that LVEF increased, LV end-systolic internal diameter and LV end-diastolic internal diameter decreased, and ventricular remodeling improved after surgery compared with the preoperative period (P<0.05). The postoperative improvement was more obvious in group A than in groups B and C. Three months after surgery, LVEF increased to 55%, the LV end-systolic internal diameter decreased to 39 mm, and the LV end-diastolic internal diameter decreased to about 55 mm in each group (P>0.05). Conclusions Patients with heart valve disease and low LVEF should be actively treated with heart valve surgery, which can significantly improve the patient's left ventricular reverse remodeling and cardiac function, thereby facilitating survival.

Do Not Withhold Mitral Surgery from Patients with Poor Left Ventricular Function. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58091220. [PMID: 36143897 PMCID: PMC9501001 DOI: 10.3390/medicina58091220] [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: 06/20/2022] [Revised: 08/24/2022] [Accepted: 08/31/2022] [Indexed: 12/02/2022]
Abstract
Background and Objectives: Increasing reluctance to perform surgical mitral valve repair or replacement particularly in high-risk patients with poor left-ventricular function is trending. These patients are increasingly treated interventionally, e.g., by MitraClip, but often show only low to moderate improvement. The primary objective of the study was to investigate whether left ventricular ejection fraction (LVEF) influences postoperative mortality. Materials and Methods: The study included 903 patients undergoing mitral valve repair or replacement between 2009 and 2021. Statistical comparison was performed between patients with LVEF ≤ 30% and LVEF > 30%. Finally, statistical analysis was performed according to propensity score matching (1:3 PS matching). Results: No significant difference in in-hospital mortality was found before and after matching regarding LVEF ≤ 30% and LVEF > 30% (Pre: 10.8% vs. 15.1%, p = 0.241, after: 11.6% vs. 18.1%, p = 0.142). After PS matching, the 112 patients with LVEF ≤ 30% compared with 336 patients with LVEF > 30% showed a significantly higher preoperative NT-proBNP (p < 0.001), larger diameters at preoperative left ventricle and atrium (p < 0.001), lower preoperative TAPSE (p = 0.003) and PAP (p = 0.003), and more dilated cardiomyopathy and chronic kidney disease (p < 0.001, p = 0.045). Conclusions: The results of this study demonstrate that poor preoperative LVEF alone does not play a significant role in postoperative outcome and long-term mortality. Prognosis appears to be multifactorial. Poor preoperative LVEF is not a contraindication for surgery and does not justify primary interventional treatment accepting inferior hemodynamic results impeding outcome.
