Nationwide database study of postoperative sequelae and in-hospital mortality in super-elderly hip fracture patients

Abstract Introduction The risk of postoperative sequelae and in-hospital mortality in Japanese patients aged 90 years and older with hip fractures is unexplored. This study aims to use a comprehensive medical claims database in Japan to compare super-elderly patients aged 90 years and older with elderly aged 65–89 and clarify the risk of sequelae and in-hospital mortality in super-elderly patients. Materials and methods We retrospectively analyzed the Diagnosis Procedure Combination (DPC) database for all of Japan from April 2016 to March 2022. Medical records from approximately 1100 DPC-related hospitals were provided with consistent consent during this period. In this study, we focused on super-elderly patients and examined the association with the risk of postoperative pneumonia, pulmonary embolism, myocardial infarction, urinary tract infection, acute renal dysfunction, subsequent cognitive dysfunction, and in-hospital mortality after one-to-one propensity score matching. Results After performing propensity score matching based on sex and comorbidities, 129,953 pairs of patients were identified. These pairs were compared to elderly and super-elderly patients. The results of this study showed that compared with hip fractures in the elderly, hip fractures in the super-elderly were associated with an increased risk of pneumonia, urinary tract infection, acute renal dysfunction, subsequent cognitive dysfunction, and in-hospital mortality after adjustment for confounders. The odds ratio of in-hospital mortality was 2.190 (95% CI 2.062–2.325). Conclusion As it has been shown that super-elderly patients with hip fractures are at greater risk of respiratory and urinary tract infections and increased in-hospital mortality, careful attention should be required for perioperative management.

Heterogeneous Treatment Effects of High-Frequency Oscillatory Ventilation for Acute Respiratory Distress Syndrome: A Post Hoc Analysis of the Oscillation for Acute Respiratory Distress Syndrome Treated Early (OSCILLATE) Trial

OBJECTIVES: We sought to evaluate whether different subgroups of adults with acute respiratory distress syndrome (ARDS) respond differently to high-frequency oscillatory ventilation (HFOV). DESIGN: The Oscillation for ARDS Treated Early (OSCILLATE) trial was a randomized controlled trial of HFOV vs. conventional ventilation that found an increased risk of in-hospital mortality (primary outcome) with HFOV. In a post hoc analysis, we applied three different approaches to evaluate heterogeneity of treatment effect for in-hospital mortality: 1) subgroup analyses based on baseline Pao 2:Fio 2 ratio and oxygenation index (OI); 2) a risk-based approach using a multivariable outcome prediction model; and 3) a clustering approach via multivariable latent class analysis. We used multivariable logistic regression models to assess for interaction. SETTING: Thirty-nine ICUs, five countries. SUBJECTS: Five hundred forty-eight adults with moderate to severe ARDS. INTERVENTIONS: HFOV vs. conventional mechanical ventilation with low tidal volume and higher positive end-expiratory pressure. MEASUREMENTS AND MAIN RESULTS: The effect of HFOV on in-hospital mortality was consistent across categories of Pao 2:Fio 2 ratio (adjusted odds ratio [aOR], 2.04; 95% CI, 1.32–3.17 and aOR, 1.16; 95% CI, 0.49–2.75 for groups with Pao 2:Fio 2 above or equal to 80, vs. below 80, respectively; interaction p = 0.23) and OI (aOR, 1.78; 95% CI, 0.67–4.70; aOR, 3.19; 95% CI, 1.44–7.09; aOR, 1.73; 95% CI, 0.82–3.65; and aOR, 1.33; 95% CI, 0.61–2.90 for quartiles of baseline OI, respectively; interaction p = 0.44). Point estimates for the effect of HFOV were consistent across risk categories (aOR, 2.44; 95% CI, 0.40–14.83; aOR, 1.69; 95% CI, 0.75–3.85; and aOR, 2.10; 95% CI, 0.59–7.54 for the lowest, moderate, and highest risk categories, respectively; interaction p = 0.32). Using a clustering approach, point estimates for HFOV were also consistent (cluster 1: aOR, 1.85; 95% CI, 1.15–3.00 and cluster 2: aOR, 1.75; 95% CI, 0.91–3.38; interaction p = 0.75). CONCLUSIONS: We did not identify heterogeneity in the effect of HFOV across different subgroups of patients with ARDS.

Burden of Respiratory Syncytial Virus Infection in Children and Older Patients Hospitalized with Asthma: A Seven-Year Longitudinal Population-Based Study in Spain

(1) Background: To describe hospitalizations due to respiratory syncytial virus (RSV) infection among children and elderly patients with asthma. (2) Methods: We used a nationwide discharge database to select patients with asthma aged 0 to 15 years and ≥65 years admitted to Spanish hospitals from 2016 to 2022. (3) Results: We identified 49,086 children and 471,947 elderly patients hospitalized with asthma (3.52% and 0.51%, respectively, with RSV). The proportion of RSV increased over time in children with asthma (from 1.44% to 7.4%, p < 0.001) and in elderly individuals (from 0.17% to 1.01%, p < 0.001). Among children with RSV infection, the presence of influenza (OR 3.65; 95% CI 1.46–9.1) and pneumonia (OR 1.85; 95% CI 1.02–3.55) increased the risk of poor outcome. The presence of RSV was associated with severity in these patients, defined by use of mechanical ventilation and/or admission to the intensive care unit (OR 1.44; 95% CI 1.11–1.86). In elderly patients with RSV infection, older age, congestive heart failure, COVID-19, and pneumonia increased the risk of in-hospital mortality (IHM). However, RSV infection was not associated with IHM (OR 0.88; 95% CI 0.68–1.15) in these patients. (4) Conclusion: Our results highlight the impact of RSV infection in children and elderly patients hospitalized with asthma. Strategies to improve surveillance, prophylaxis, and management of RSV infection should be evaluated.

Impact of Precision in Staging Acute Kidney Injury and Chronic Kidney Disease on Treatment Outcomes: An Observational Study

(1) Background: “Kidney Disease: Improving Global Outcomes” (KDIGO) provides guidelines for identifying the stages of acute kidney injury (AKI) and chronic kidney disease (CKD). A data-driven rule-based engine was developed to determine KDIGO staging compared to KD-related keywords in discharge letters. (2) Methods: To assess potential differences in outcomes, we compare the patient subgroups with exact KDIGO staging to imprecise or missing staging for all-cause mortality, in-hospital mortality, selection bias and costs by applying Kaplan–Meier analysis and the Cox proportional hazards regression model. We analysed 63,105 in-patient cases from 2016 to 2023 at a tertiary hospital with AKI, CKD and acute-on-chronic KD. (3) Results: Imprecise and missing CKD staging were associated with an 85% higher risk of all-cause and in-hospital mortality (CI: 1.7 to 2.0 and 1.66 to 2.03, respectively) compared to exact staging for any given disease status; imprecise or missing AKI staging increased in-hospital mortality risk by 56% and 57% (CI: 1.43 to 1.70 and 1.37 to 1.81, respectively) in patients with AKI. (4) Conclusions: Exact staging is associated with better outcomes in KD management. Our study provides valuable insight into potential quality and outcome improvements and lower costs, considering elderly patients, women and patients with acute-on-chronic KD as the most vulnerable.

Association between triglyceride-glucose index and in-hospital all-cause mortality under different glucose metabolism status among patients with coronary artery disease

BackgroundThis current study aimed to investigate the relationship between the triglyceride-glucose (TyG) index and in-hospital all-cause mortality of coronary artery disease (CAD) in patients with different glucose metabolic statuses.MethodsParticipants were divided into three groups according to tertiles of the TyG index. Glucose metabolic status was classified as normal glucose regulation, pre-diabetes mellitus, and diabetes mellitus (DM). The primary outcome was in hospital all-cause mortality.ResultsWe observed a significant relationship between the TyG index and in-hospital deaths of patients with CAD in this study. After adjusting for multiple factors in the logistic regression model, the TyG index was still an independent risk factor, and the T3 group (OR, 2.311; 95% CI = 1.237–4.317; P = 0.009) was correlated with a 2.311-fold risk compared with the T1 group. In the subgroup analysis of different glucose metabolic status, the T3 group (OR, 1.541; 95% CI: 1.013–2.344; P = 0.043) were associated with a significantly higher risk of in-hospital deaths in CAD patients with DM.ConclusionsAn increased TyG index was correlated with a higher risk of in-hospital all-cause mortality. Our study indicated that TyG index could be a valuable predictor of in-hospital death of CAD patients, especially for individuals with DM.

Construction and validation of a clinical prediction model for sepsis using peripheral perfusion index to predict in-hospital and 28-day mortality risk.

Sepsis is a clinical syndrome caused by infection, leading to organ dysfunction due to a dysregulated host response. In recent years, its high mortality rate has made it a significant cause of death and disability worldwide. The pathophysiological process of sepsis is related to the body's dysregulated response to infection, with microcirculatory changes serving as early warning signals that guide clinical treatment. The Peripheral Perfusion Index (PI), as an indicator of peripheral microcirculation, can effectively evaluate patient prognosis. This study aims to develop two new prediction models using PI and other common clinical indicators to assess the mortality risk of sepsis patients during hospitalization and within 28 days post-ICU admission. This retrospective study analyzed data from sepsis patients treated in the Intensive Care Unit of Peking Union Medical College Hospital between December 2019 and June 2023, ultimately including 645 patients. LASSO regression and logistic regression analyses were used to select predictive factors from 35 clinical indicators, and two clinical prediction models were constructed to predict in-hospital mortality and 28-day mortality. The models' performance was then evaluated using ROC curve, calibration curve, and decision curve analyses. The two prediction models performed excellently in distinguishing patient mortality risk. The AUC for the in-hospital mortality prediction model was 0.82 in the training set and 0.73 in the validation set; for the 28-day mortality prediction model, the AUC was 0.79 in the training set and 0.73 in the validation set. The calibration curves closely aligned with the ideal line, indicating consistency between predicted and actual outcomes. Decision curve analysis also demonstrated high net benefits for the clinical utility of both models. The study shows that these two prediction models not only perform excellently statistically but also hold high practical value in clinical applications. The models can help physicians accurately assess the mortality risk of sepsis patients, providing a scientific basis for personalized treatment.

Temporal trends (2003–2018) of in-hospital and 30-day mortality in patients hospitalized with acute heart failure

BackgroundLimited temporal data on in-hospital mortality trends of patients hospitalized with acute heart failure (AHF) have been reported. We evaluated whether, in AHF hospitalized patients, the rate of in-hospital and 30-day mortality, and 30-day re-hospitalization for AHF have changed in the past 15 years. Methods and resultsWe examined administrative data from the Lombardy region, Italy and analysed data of all adults hospitalized for AHF from 2003 to 2018. Patients were stratified according to the hospitalization period: 2003–2006; 2007–2010; 2011–2014; 2015–2018. Primary endpoint was the comparison of in-hospital mortality rates among periods. Secondary endpoints were 30-day mortality rates and temporal trends of re-hospitalization for AHF. During this period, 414,164 hospitalizations with a primary diagnosis of AHF were identified, involving 286,028 patients aged 18 and older. In-hospital and 30-day mortality in the entire cohort showed a progressive increase over time (from 6.7 % to 8.5 % and from 12.4 % to 14.5 %, respectively). Thirty-day re-hospitalization for AHF was 2 %, showing a progressive decrease over the years. However, patient’ age and complexity increased in the most recently hospitalized patients. After adjusting for major confounders, in-hospital and 30-day mortality risks were similar moving from one study period to the next (relative risk for trend 1.00 [95 % CI 0.99–1.01] and 1.00 [95 % CI 0.98–1.01], respectively), while that of 30-day AHF re-hospitalization decreased progressively (hazard ratio for trend 0.86 [95 % CI 0.84–0.88]). ConclusionsIn our study, the increasing age and complexity of patients largely accounted for the continued rise in early mortality observed in patients hospitalized with AHF.

The Effects of Prophylactic Laxative Use on Critically Ill Patients Requiring Mechanical Ventilation: A Retrospective Cohort Study

Objective: To investigate the effects of prophylactic use of stimulant laxatives and/or docusate on the clinical outcomes in critically ill patients who required mechanical ventilation (MV). Methods: A single-center, retrospective, cohort study was conducted. Patients who received MV in the first 24 h after intensive care unit (ICU) admission were enrolled and divided into four groups: non-laxative, stimulant laxatives, docusate, and stimulant laxatives–docusate combination. The primary outcome was in-hospital mortality. The major secondary outcomes included ICU-free days and ventilator-free days at 28 days; the other outcomes were ventilation-associated pneumonia (VAP), enterobacterial infection, diarrhea, and electrolyte disturbances. Inverse probability treatment weighting (IPTW) was used to adjust for confounders. Results: A total of 2129 patients were included in this study, 263 of whom received stimulant laxatives, 253 received docusate, 368 received a combination, and 1245 did not receive any laxative. The prophylactic use of docusate was associated with a decreased risk of in-hospital mortality (OR: 0.59, 95% CI 0.42 to 0.83, p = 0.002) and VAP (OR: 0.62, 95% CI 0.47 to 0.81, p = 0.001). It was also associated with an increase in ICU-free days at 28 days (β: 0.89, 95% CI 0.83 to 0.95, p < 0.001). Importantly, laxatives prophylaxis was not associated with increased risks of diarrhea, electrolyte disturbances, and enterobacterial infections. Conclusions: Prophylactic use of docusate may improve certain prognoses and does not demonstrate any adverse events. However, further research is necessary to determine the optimal regimen and dosage of prophylactic laxatives in this specific population.

A Novel Scoring System for Assessing In-Hospital Mortality Risk in Patients With Liver Cirrhosis

A Novel Scoring System for Assessing In-Hospital Mortality Risk in Patients With Liver Cirrhosis

Characteristics, temporal trends and outcomes of intravenous thrombolysis in Chinese patients aged>80 years who had a stroke.

To date, no large cohort study has investigated the effects of intravenous thrombolysis (IVT) in Chinese patients aged over 80 years who had a stroke. This study aimed to assess the trends in the use of alteplase, the clinical characteristics and the outcomes of Chinese patients aged above 80 years who had an acute ischaemic stroke. Data for this analysis were obtained from the China Stroke Center Alliance programme, a nationwide, multicentre, prospective registry encompassing 1751 hospitals across 31 provinces, covering the period from 1 January 2018 to 14 December 2022. The primary outcome was defined as a modified Rankin Scale (mRS) Score of 0-2 at discharge. Secondary outcomes included an mRS Score of 0-1 and independent ambulation on discharge. Safety outcomes assessed were in-hospital mortality and symptomatic intracranial haemorrhage (sICH). Out of 30 902 patients over 80 years old who qualified for thrombolysis, 8673 (median age (IQR), 84 (82-87) years) received alteplase treatment. Patients administered alteplase demonstrated improved short-term functional outcomes, such as an mRS Score of 0-2 (adjusted OR (aOR) 1.12, 95% CI, 1.06 to 1.18, p<0.001), an mRS Score of 0-1 (aOR 1.14, 95% CI, 1.08 to 1.19, p<0.001) and independent ambulation at discharge (aOR 1.14, 95% CI, 1.08 to 1.20, p<0.001). Moreover, no significant increase was observed in the risk of in-hospital mortality (aOR 1.12, 95% CI, 0.93 to 1.35; p=0.23). However, the risk of sICH was significantly higher among patients treated with alteplase (aOR 3.22, 95% CI, 2.77 to 3.75; p<0.001). IVT with alteplase in elderly patients who had a stroke resulted in improved short-term functional outcomes without elevating the risk of in-hospital mortality. Nonetheless, this population remains at a higher risk of sICH.

Предикторы госпитальной летальности при экстренном хирургическом лечении острейшего расслоения аорты типа А по Стенфорду в условиях искусственного кровообращения: ретроспективное когортное исследование

INTRODUCTION: Acute Stanford type A aortic dissection is one of the most severe cardiovascular diseases with high in-hospital mortality. OBJECTIVE: To establish predictors of in-hospital mortality in the treatment of patients with acute Stanford type A aortic dissection under conditions of artificial circulation and to determine their threshold values. MATERIALS AND METHODS: Study design: retrospective, cohort, single-center. Inclusion criteria: surgical intervention with cardiopulmonary bypass, confirmed diagnosis of acute Stanford type A aortic dissection, age &gt; 18 years. The study included 51 patients: 42 men and 9 women aged from 35 to 77 years, median 59 years [47; 65]. All patients (n = 51) were treated in 2022 and were divided into 2 groups depending on the outcome: group 1 (n = 27) included those who died in the intensive care unit within 30 days, group 2 (n = 24) included survived and discharged patients. The endpoint of trial was 30-day in-hospital mortality. RESULTS: Postoperative Sequential Organ Failure Assessment (SOFA) score &gt; 7, Acute Physiology And Chronic Health Evaluation (APACHE) II score &gt; 19, and Vasoactive-inotropic score (VIS) &gt; 10, cardiopulmonary bypass time &gt; 177 minutes, and total hypothermic circulatory arrest time &gt; 30 minutes were associated with an increased risk of 30-day in-hospital mortality. CONCLUSIONS: Statistically significant predictors of hospital mortality in the treatment of patients with acute Stanford type A aortic dissection under cardiopulmonary bypass are the SOFA index, the APACHE II index and the VIS index after the end of surgery, as well as the time of cardiopulmonary bypass and the time of total hypothermic circulatory arrest.

Association of Serum Blood Urea Nitrogen to Albumin Ratio with in-Hospital Mortality in Patients with Acute Ischemic Stroke: A Retrospective Cohort Study of the eICU Database

Albumin (ALB) and blood urea nitrogen (BUN) are both associated with the prognosis of acute ischemic stroke (AIS). A recent prognostic marker, the BUN/ALB ratio (BAR), has been suggested as a simple and sensitive method to predict certain acute diseases. To determine the predictive value of BAR in relation to the risk of in-hospital mortality among AIS patients. Retrospective cohort study. Cox regression analysis was employed to assess the relationship between in-hospital mortality and BAR, with hazard ratios (HRs) and 95% confidence intervals. Subgroup analysis of acute pulmonary embolism, acute myocardial infarction (AMI), thrombolysis, thrombectomy, and septic shock was performed to further examine this relationship. The predictive value of BAR and BAR multivariate models for in-hospital mortality was evaluated and compared to BUN, ALB, the Acute Physiology and Chronic Health Evaluation IV (APACHE IV) score, and the Sequential Organ Failure Assessment Score (SOFA). Among the 1,635 eligible patients, 226 (13.81%) died during hospitalization. An elevated serum BAR level was associated with an increased in-hospital mortality risk (HR: 1.3) after covariates were adjusted. Additionally, this positive association was observed in patients without AP, AMI, thrombolysis, history of thrombectomy, or septic shock (all; p < 0.05). The efficacy of the BAR multivariate model in predicting in-hospital mortality among AIS patients was superior to that of both APACHE IV and SOFA, with an area under the curve of 0.87. Serum BAR exhibits the potential to identify AIS patients with high mortality risk, which may contribute to enhanced disease surveillance and risk stratification.

Serum Osmolality as a Predictor of Renal Function Decline: A Retrospective Cohort Study

Background and Aims: Dehydration is a prevalent and costly healthcare concern, linked to heightened risks of acute kidney injury and in-hospital mortality. Despite its significance, limited evidence exists regarding its prevalence and correlation with renal function decline in apparently healthy individuals. This retrospective cohort study aimed to investigate the prevalence and association of dehydration with renal function decline and the development or progression of chronic kidney disease (CKD) in the general population. Methods: The medical records of subjects undergoing annual health check-ups from 2016 to 2019 at a single center in Taiwan were analyzed, and those with CKD stage V, insufficient data, or an increased estimated glomerular filtration rate (eGFR) were excluded. Serum osmolality, eGFR, and relevant parameters were measured. Logistic regression and Kaplan–Meier analyses were used to assess associations between osmolality and CKD-related outcomes. Results: Among the 4449 eligible subjects, those in the higher osmolality quartiles had an elevated risk of CKD or CKD progression. Multivariate analyses identified age, systolic blood pressure, serum osmolality, uric acid, proteinuria, and a history of diabetes as independent risk factors, with high-density lipoprotein being protective. Cumulative incidence curves demonstrated a significant increase in the risk of CKD with increasing osmolality levels. Restricted cubic spline analyses confirmed a nonlinear relationship between osmolality and CKD risk. Conclusions: Elevated serum osmolality independently predicted renal function decline and CKD development in apparently healthy individuals, and this effect persisted after adjusting for established risk factors. Our findings underscore the importance of addressing dehydration as a modifiable risk factor for CKD.

Biochemical variables as predictors of in-hospital mortality in patients with acute coronary syndrome

Abstract Background There is a constant search of easily obtainable variables that can be put in relation with in-hospital mortality, enabling creation of prediction risk models in patients treated for acute coronary syndrome. Purpose The main goal of this study was to unravel what is the profile of the patients with acute coronary syndrome in risk of in-hospital mortality, based on simple biochemical variables acquired at the time of hospital admission. Methods This was a single-center cross-sectional cohort study on 3007 pts. treated for ACS (STEMI and NSTEMI). Venous blood sample at hospital admission was acquired for every patient. Patients were comparatively analyzed for their biochemical variables derived from venous blood sample, based on occurrence of in-hospital mortality. Results Out of 3007 pts, 988 (28.2%) were females, and 2519 (71.8%) males, at mean age 62.6 +/- 11.2 y. In-hospital mortality rate was 4.8% (145 out of 3007). We subjected to comparative analyzed hemogram, markers of renal function including sodium and potassium, glycemic profile, complete lipid panel (including ApoA1 and ApoB), and highly sensitive troponin. Significant association with in-hospital mortality was found for: hsTn, stress glycemia and glicated hemoglobin, BUN, creatinite, eGFR, sodium, potasium, full lipid panel [except for HDL-C and Lp(a)]. In the second step, markers proven to be significantly different were subjected to multivariate binary logistic regression (backward conditional). We designed two models, one that included ApoA1 and ApoB (including 1816 pts. for whom we had data), and the second without these two parameters (including 3007 pts.). With the first model we identified: Advanced age, stress glycemia, WBC, eGFR, HDL-C and ApoA1 as independent predictors. Surprisingly, HDL-C was found to be strong independent predictor in multivariate analyzis. While with second modeling we identified advanced age, hsTn, stress glycemia, RBC, WBC, BUN and eGFR as independent predictors. Conclusion Advanced age is a strong independent predictor in any modelling. When we have a possibility to obtain a complete lipid panel, beside stress glycemia and WBC as markers of the degree of neuro-hormonal activation and inflammation, and renal function, HDL-C and ApoA1 seems to be strong negative independent predictors. In the absence of this data beside aforementioned markers of neurohormonal activation and inflammation, and renal function, the degree of myocardial injury plays a significant role. According to our data it seems reasonable to obtain complete lipid panel at hospital admission.Multivariate logistic regression modelsAge distribution across genders

Trends in intracardiac thrombus formation in myocardial infarction patients after PCI: a nationwide analysis

Abstract Background Percutaneous coronary interventions (PCI) have become a crucial therapeutic option for myocardial infarction (MI) patients. However, the clinical outcomes and complications associated with PCI, especially in relation to intracardiac thrombus, remain a subject of concern. Purpose We aimed to examine the real-world clinical outcomes and temporal trends of in-hospital mortality and intracardiac thrombus among myocardial infarction patients treated with PCI between 2017 and 2020. Methods The National Inpatient Sample was queried from 2017 to 2020 to identify all adults with myocardial infarction (ST elevation and Non-ST elevation MI) who underwent PCI using the International Classification of Diseases, 10th Revision codes. The Cochran-Armitage test assessed the linear trend of in-hospital intracardiac thrombus and mortality. Multivariable regression analysis was conducted to assess the association of PCI with in-hospital mortality and intracardiac thrombus. The Charlson comorbidity index was used to adjust for confounders. Results are represented as adjusted odds ratios (ORs) with their respective 95% confidence intervals (CIs). Results Of the 1,394,650 patients who underwent PCI, 8,080 (0.58%) experienced intracardiac thrombus, with a mean age of 62, predominantly male (76%). Despite decreasing rates of PCI noted over this 4-year period (Figure 1). There was an upward trend in in-hospital intracardiac thrombus revealed over a 4-year period (trend: 0.54%, p &amp;lt; 0.001). PCI was associated with a yearly increase in intracardiac thrombus in 2018 in 0.54% of patients (OR = 1.36, 95% CI 1.2 to 1.6, p &amp;lt; 0.001). In 2019, 0.56% of patients experienced intracardiac thrombus (OR = 1.4, 95% CI 1.2 to 1.6, p = 0.001); in 2020, 0.72% of patients (OR = 1.8, 95% CI 1.6 to 2.1, p = 0.008), compared to 2017 (0.4%). Mortality rates for PCI and ICT patients were 6% in 2017 (OR 2.2, p &amp;lt; 0.001, 95% CI 1.4-3.2), decreased to 5% in 2018 (OR 1.8, p &amp;lt; 0.004, 95% CI 1.2-2.6) and 4.7% in 2019 (OR 1.6, p &amp;lt; 0.01, 95% CI 1.1-2.4), then rose to 6.6% in 2020 (OR 2, 95% CI 1.4-2.8) (Table 1). Overall, in-hospital mortality was 5.6% (OR = 1.6, 95% CI 1.3 to 1.9, p &amp;lt; 0.001) among patients who had intracardiac thrombus related to PCI. Conclusions Our findings indicate a significant increase in intracardiac thrombus rates among MI patients treated with PCI from 2017 to 2020, accompanied by a considerable risk of in-hospital mortality. These outcomes underscore the critical need for vigilant monitoring and enhanced management approaches in this patient demographic.Figure 1Table 1

Valve unit instead of intensive care unit admission after transcatheter edge-to-edge tricuspid valve repair

Abstract Background Standardization of periprocedural pathways reduces the length of hospital stay and thus healthcare costs and increases patient safety. Post-procedure admission to the intensive care unit (ICU) after transcatheter edge-to-edge tricuspid valve repair (T-TEER) has been the standard of care. Due to the COVID-19 pandemic related decline in high-care hospital beds, our center established primary admission to a dedicated general cardiologic care ward, the valve unit (VU). Aim To assess benefits and risks of admission to the VU instead of ICU after T-TEER. Methods This retrospective observational study included 270 consecutive patients who underwent T-TEER between March 2017 and June 2023 at our university hospital. Patients were admitted to the ICU post-procedure up to April 9th 2020 as standard (ICU-group, n = 53). Subsequent patients were planned for admission to a dedicated VU (VU-group, n = 217). We compared the groups and assessed length of hospital stay and in-hospital complications. In the VU-group, we examined unplanned transfer to the ICU (cross-over) and its predictors. Results Monitoring at the VU included continuous telemetric ECG-recording, oxygen saturation assessment, periodical blood pressure measurements and 24-hours physician presence. In contrast to the ICU, only non-invasive blood pressure measurements, less frequent laboratory controls and less intense fluid monitoring took place. The postinterventional hospital stay of patients with planned VU admission was significantly shorter compared to patients with planned ICU admission (median 4 (interquartile range (IQR) 3 - 5) vs. 4 (IQR 4 - 5) days, p = 0.030). Remarkably, overall complication rates were low and cardiogenic shock, infections, bleeding, vascular complications, delirium and acute kidney injury requiring dialysis were similar in both groups. 37 patients that were planned for VU had to cross over to unplanned ICU admission (17.1 %). Patients that had crossed over to unplanned ICU treatment had significantly higher risk for acute kidney injury (20.0 vs. 10.0%, p = 0.039) and in-hospital mortality (5.6 vs. 0%, p = 0.045). Higher systolic pulmonary artery pressure (sPAP) (OR 1.048, 95 %-CI 1.015 – 1.082, p = 0.003), NYHA functional class &amp;gt;= III (OR 9.176, 95 % CI 1.141 – 74.396, p = 0.037), and pre-interventional tricuspid regurgitation (TR) grade V (OR 2.941, 95 % CI 1.089 – 7.970, p = 0.033) were found to independently predict cross-over to unplanned ICU treatment. Conclusion Postinterventional admission to the VU instead of ICU after T-TEER shortens postprocedural hospital stay. A small proportion of had an unplanned transfer to ICU, which was accompanied by slightly higher complication rates. This cross-over affects patients with more advanced disease indicated by high pulmonary pressures, NYHA class and TR grade. Thus, admission to a valve unit is favorable for most patients after T-TEER, but those with advanced disease should be monitored more closely.

Infective endocarditis - characteristics and long-term outcomes in patients with congenital heart disease are distinct from those without congenital heart disease

Abstract Background Patients with congenital heart disease (CHD) form a high-risk niche among patients considered at high-risk of infective endocarditis (IE). Their life-long exposure to the risk of IE, starting from birth, necessitates a nuanced approach to both prevention and treatment strategies. However, comprehensive data from an unselected nationwide cohort, including children, are lacking. Purpose This study sets out to compare characteristics and associated outcomes among patients with IE with and without CHD. Methods Using nationwide registries, all Danish patients diagnosed with IE from 1977-2021 were identified and stratified on whether they had a diagnosis of CHD, regardless of its complexity. Characteristics prior to and during admission as well as associated outcomes (i.e., in-hospital mortality, 1-year mortality, and 10-year mortality, and IE recurrence) were compared between groups. Results In total, 14,040 patients were diagnosed with IE from 1977-2021 including 895 (6.4%) with a diagnosis of CHD. Patients with versus without CHD were significantly younger at time of IE diagnosis (median age 38.8 years [IQR 21.2-56.4 years] versus 70.7 years [IQR 58.8-78.9 years], Figure 1) and less comorbid. Patients with versus without CHD were hospitalized due to IE for a similar period of time but more often underwent cardiac surgery during admission (44.9% versus 21.3%). The IE-related bacteremia was significantly different between groups: the most common bacteriemia in relation to IE was Streptococci (29.9%) in patients with CHD and Staphylococcus Aureus (29.9%) in patients without CHD. Patients with CHD were associated with a significantly lower risk of in-hospital mortality (6.4% versus 19.8%), 1-year mortality (10.5% versus 32.4%) and 10-year mortality (21.3% versus 58.7%) compared with those without CHD. The 10-year incidence of IE recurrence was similar among groups (p-value 0.5). Conclusions Patients with CHD who develop IE are distinctive from patients with IE without CHD in terms of characteristics as well as long-term outcomes. Notably, our findings stress a key point: the majority of children and adolescents with IE have a CHD. These unselected findings should help guide future preventive strategies, diagnosis, and management.

Guideline-directed medical therapy and in-hospital mortality in acute coronary syndrome patients with advanced renal dysfunction

Abstract Background It is unclear whether early (initiated within 24 hours of admission) guideline-directed medical therapy [GDMT, i.e., the combined use of β-blocker, angiotensin converting enzyme inhibitor/angiotensin receptor blocker, dual antiplatelet drugs and statin] could benefit acute coronary syndrome (ACS) patients with advanced renal dysfunction [estimated glomerular filtration rate (eGFR) &amp;lt; 30 mL/min/1.73 m2]. Objectives The purpose of this study was to verify whether GDMT could improve in-hospital mortality in ACS patients with advanced renal dysfunction. Methods This study included 3,288 and 3,520 ACS patients with admission with advanced renal dysfunction from the CNEDSSP and CCC-ACS cohorts, respectively. Multivariable-adjusted analysis and propensity score matching (PSM) were employed to assess the impact of GDMT on in-hospital mortality. Results In a pooled analysis of the CNEDSSP and CCC-ACS cohorts, early GDMT was associated with significantly lower in-hospital mortality (relative ratio [RR]: 0.62, 95% CI: 0.47 to 0.81). PSM revealed an attenuation of the association of in-hospital mortality with early GDMT in ACS patients, with statistically significant associated reductions observed only in myocardial infarction (MI) patients (hazard ratio [HR]: 0.45, 95% CI: 0.27 to 0.75 in CNEDSSP cohort; HR: 0.48, 95% CI: 0.27 to 0.84 in CCC-ACS cohort). A random-effect pooled analysis for MI patients with admission advanced renal dysfunction demonstrated a 56% lower in-hospital mortality among GDMT users (RR: 0.44, 95% CI: 0.31 to 0.65). Conclusions This nationwide study highlights that early GDMT is associated with a reduced risk of in-hospital mortality in ACS patients (particularly in MI patients) with advanced renal dysfunction.

Impact of baseline thrombocytopenia on outcomes in hospitalizations for acute coronary syndrome and non-elective percutaneous coronary intervention: meta-analysis

Abstract Background Thrombocytopenia's impact on acute coronary syndromes (ACS) outcomes is poorly understood. A systematic review and meta-analysis aim to elucidate its influence on both short-term and long-term clinical endpoints, guiding tailored management strategies for improved patient care. Methods Our meta-analysis is registered on PROSPERO (CRD42024511832). We conducted a systematic search of PubMed and SCOPUS databases up to February 2024, utilizing keywords to identify studies on ACS or non-elective PCI populations with or without baseline thrombocytopenia (TP) reporting on in-hospital and long-term outcomes. Baseline TP was defined as a platelet count less than 150 x 10⁹/L and had to be established before hospitalization or ACS management or intervention. Binary random effects models were used to estimate pooled unadjusted odds ratios (OR) and 95% confidence intervals (CI). Sensitivity analysis was done by the leave-one-out method, and the heterogeneity was assessed with the I² statistics. Results From 2,831 identified studies, 10 were identified as eligible for inclusion in our pooled analysis and included 6,588,688 patients. Thrombocytopenia was associated with higher risks of in-hospital mortality (OR=1.89, 95% CI:1.55-2.30, p&amp;lt;0.01), in-hospital Major adverse cardiovascular events (MACE) (OR=1.99, 95% CI:1.63-2.43, p&amp;lt;0.01), and in-hospital bleeding (OR=2.62, 95% CI:1.89-3.64, p&amp;lt;0.01). Long-term follow-up revealed increased risks of MACE (OR=1.80, 95% CI 1.49-2.18, p&amp;lt;0.01), bleeding (OR=1.63, 95% CI:1.63-2.25, p&amp;lt;0.01), and cardiovascular mortality (OR=2.07, 95% CI:1.76-2.42, p&amp;lt;0.01) with thrombocytopenia. No significant difference was found in in-hospital stroke outcomes and long-term outcomes for stroke and recurrent myocardial infarction between thrombocytopenic and non-thrombocytopenic groups. Conclusion Thrombocytopenia worsens ACS outcomes. Vigilance and tailored management are crucial for mitigating its impact on patient prognosis. Further research is needed for better interventions.Secondary outcomes forest plot

Impact of late reperfusion therapy in patients with inferior ST-segment elevation myocardial infarction and right ventricular dysfunction: one size never fits all

Abstract Background A significant proportion of ST-segment elevation myocardial infarction (STEMI) patients present late to the emergency room with limited evidence of benefit of reperfusion after 12 hours of symptom onset. Inferior myocardial infarction (MI) with right ventricle (RV) dysfunction is associated with high morbidity and mortality, however, the RV has a unique physiology that allows it to withstand ischemia better and recover faster. Purpose To compare adverse in-hospital cardiovascular events in latecomers with inferior STEMI and RV dysfunction admitted to a cardiovascular intensive care unit (CICU) from a low-to-middle-income country, who underwent late reperfusion treatment versus conservative treatment. Methods A retrospective cohort study was conducted from March 2022 to April 2023. Patients with inferior STEMI and RV dysfunction who received late reperfusion treatment were included. RV dysfunction was defined as a TAPSE &amp;lt;17 mm, tricuspid annular systolic velocity on TDI &amp;lt;9.5 cm/s, or a fractional area change &amp;lt;35%. Late reperfusion was defined as primary percutaneous coronary intervention (PCI) performed after 12 hours of symptom onset or rescue PCI after 12 hours of failed fibrinolysis. The primary outcome was in-hospital all-cause mortality. Secondary outcomes were cardiovascular death, reinfarction, stroke, cardiogenic shock, and mechanical complications. Results During the specified period, a total of 106 patients met the inclusion criteria from a total of 1,786 patients admitted to the CICU in our center. Only 60 patients underwent late PCI, accounting for 56% of the cases, with a median time of onset of symptoms to reperfusion of 19.4 hours (IQR: 15.7, 30.2). The average age was 66.5 ± 10.4 years, and 28% were women. Although the all-cause death rate was lower among late PCI group (13.3% vs 26.1%; p=0.096), this difference did not reach statistical significance in the bivariate analysis. Stratified by cardiogenic shock, a lower rate of all-cause mortality was also observed (33% vs 55%, p=0.15). The incidence of reinfarction was significantly lower in the late PCI group (0% vs 13%, p=0.004). In the multivariate analysis, adjusting for those who underwent PCI between 12-48 hours, revascularization of latecomers was independently associated with a significant reduction of mortality (adjusted OR 0.22; 95% CI 0.05-0.92; p=0.038). In a post-hoc analysis, late PCI showed a lower association with the composite outcome of all-cause mortality and reinfarction (adjusted OR 0.16, 95% CI 0.04-0.56; P=0.004). Conclusion(s) Our study demonstrates that implementing a reperfusion strategy in latecomers with inferior STEMI and RV dysfunction significantly reduces the risk of in-hospital mortality and reinfarction. This suggests a potential benefit of expanding the therapeutic window for PCI in this high-risk population. However, prospective studies are needed to conclude these preliminary findings.
