Risk Factors for Adverse In-Hospital Outcomes in Patients With Traumatic Blunt Thoracic Aortic Injuries Undergoing Thoracic Endovascular Aortic Repair (TEVAR): An Analysis of the US Nationwide Inpatient Sample.

Thoracic endovascular aortic repair (TEVAR) is a treatment for traumatic blunt thoracic aortic injury (BTAI) with good survival rates and safety. However, there is limited study on the risk factors for in-hospital mortality and complications. This study aimed to identify risk factors associated with poor in-hospital outcomes after TEVAR. This is a population-based, retrospective observational study. Data of adults ≥20 years admitted for BTAI who received TEVAR were extracted from the Nationwide Inpatient Sample (NIS) database 2005 to 2018. The primary outcome was in-hospital mortality, and the secondary outcomes were length of stay (LOS) and unfavorable discharge (ie, non-routine discharge, including nursing homes or long-term care facilities). Associations between study variables and in-hospital outcomes were determined using univariate and multivariable logistic and linear regression analyses. Data of 1095 participants (representing 5360 hospitalized patients in the United States) were analyzed. Multivariable analysis revealed that older age (adjusted odds ratio [aOR]=1.02) and having at least 1 perioperative complication (aOR=4.01) were significantly associated with increased risk for in-hospital mortality. Patients with at least 1 perioperative complication (aOR=11.19) had significantly increased odds for prolonged LOS. Risk for unfavorable discharge was significantly increased by older age (aOR=1.02), household income at quartile 2 (aOR=1.58), Charlson Comorbidity Index (CCI) 2 to 3 (aOR=1.66), and having at least 1 complication (aOR=3.94). Complications including perioperative cerebrovascular accident (CVA) (aOR=2.75), venous thromboembolism (VTE) (aOR=2.87), pneumonia (aOR=3.93), sepsis (aOR=4.69), infection (aOR=4.49), respiratory failure (aOR=4.55), mechanical ventilation (aOR=3.27), and acute kidney injury (AKI) (aOR=3.09) significantly predicted prolonged LOS. In adults with traumatic BTAI undergoing TEVAR, advanced age and perioperative complications are risk factors for poor in-hospital outcomes. Acute kidney injury, CVA, respiratory failure, and sepsis are strong predictors of prolonged LOS, unfavorable discharge, and in-hospital mortality. The study identifies advanced age and perioperative complications as key risk factors for poor in-hospital outcomes in patients undergoing TEVAR for BTAI. Clinicians should be vigilant in managing these patients, particularly those with comorbidities, to mitigate risks. The findings suggest a need for tailored perioperative care strategies to improve survival rates and reduce complications. This research highlights the critical importance of early identification and intervention in high-risk patients, offering an innovative approach to refining TEVAR protocols and enhancing patient outcomes in trauma care.

Outcomes in patients with anemia hospitalized for endometrial cancer resection: A nationwide analysis.

e17585 Background: Endometrial cancer is the most common gynecological malignancy, and It is notably associated with the development of anemia. In light of this, we conducted a retrospective analysis to determine the impact of anemia on patients hospitalized for endometrial cancer resection and other complications during hospitalization. Methods: We conducted a study using the National Inpatient Sample (NIS) data from 2019 and 2020 to identify patients who were admitted with a primary diagnosis of endometrial cancer resection and had a concurrent secondary diagnosis of anemia. Primary outcomes included mortality, and secondary outcomes were the length of stay, total hospitalization charges, and other adverse hospital outcomes. Multivariate logistic regression analysis was used to adjust for confounding variables. Results: A total of 375,109 patients were hospitalized for resection of Endometrial cancer, among whom 55,345 had concurrent anemia. After adjusting for confounding factors, no difference in mortality between the two groups was observed(OR=1.37, 0.91-2.07; p=0.127). However, patients with anemia had a longer length of stay (4.11 days without and 6.05 days with anemia, p<0.001) and a higher total cost of hospitalization ($ 81,112 without and $ 108,436 with anemia, p<0.001). Patients with anemia were at a higher risk of developing sepsis (OR=3.15, 2.60-3.82, p<0.001), acute respiratory failure (OR= 2.64, 2.19-3.19; p<0.001), ICU admission (OR= 2.30, 1.95-2.72; p<0.001), acute coronary syndrome (OR= 2.17, 1.06-4.43; p=0.032), acute kidney injury (OR= 2.78, 2.50-3.09; p<0.001), constipation (OR =1.51, 1.33-1.71; p<0.001), diarrhea (OR= 2.11, 1.61-2.76; p<0.001), pneumonia (OR =2.20, 1.70-2.84; p<0.001), red blood cell transfusion (OR= 9.45, 8.39-10.64; p<0.001), platelet transfusions (OR= 4.43, 3.19-6.16; p<0.001), venous thromboembolism (OR= 2.50, 2.07-3.03; p<0.001), enteral feeding (OR= 6.96, 1.59-30.43; p=0.01), parenteral feeding (OR= 2.91, 2.19-3.85; p<0.001), urinary tract infection (OR =2.08, 1.77-2.43; p<0.001), and the involvement of palliative care (OR= 1.59, 1.18-2.13; p<0.001). There was no difference in having chemotherapy in both groups (OR 0.79, 95% CI 0.29-2.12, p=0.652). Conclusions: Anemia is associated with increased healthcare resource utilization and adverse in-hospital outcomes in patients undergoing resection of Endometrial cancer. Anemia might not be the only predictor of mortality, but identifying and treating it before any interventions can decrease the risk of adverse outcomes and improve quality of life. [Table: see text]

Impact of COVID-19 infection among patients hospitalized for conventional pacemaker implantation: Analysis of the Nationwide Inpatient Sample (NIS) 2020.

The cardiac pacemaker is indicated for treating various types of bradyarrhythmia, providing lifelong cardiovascular benefits. Recent data showed that COVID-19 has impacted procedure numbers and led to adverse long-term outcomes in patients with cardiac pacemakers. However, the impact of COVID-19 infection on the in-hospital outcome of patients undergoing conventional pacemaker implantation remains unclear. Patients aged above 18 years who were hospitalized for conventional pacemaker implantation in the Nationwide In-patient Sample (NIS) 2020 were identified using relevant ICD-10 CM and PCS codes. Multivariable logistic and linear regression models were used to analyze pre-specified outcomes, with the primary outcome being in-patient mortality and secondary outcomes including system-based and procedure-related complications. Of 108 020 patients hospitalized for conventional pacemaker implantation, 0.71% (765 out of 108 020) had a concurrent diagnosis of COVID-19 infection. Individuals with COVID-19 infection exhibited a lower mean age (73.7 years vs. 75.9 years, p = .027) and a lower female proportion (39.87% vs. 47.60%, p = .062) than those without COVID-19. In the multivariable logistic and linear regression models, adjusted for patient and hospital factors, COVID-19 infection was associated with higher in-hospital mortality (aOR 4.67; 95% CI 2.02 to 10.27, p < .001), extended length of stay (5.23 days vs. 1.04 days, p < .001), and linked with various in-hospital complications, including sepsis, acute respiratory failure, post-procedural pneumothorax, and venous thromboembolism. Our study suggests that COVID-19 infection is attributed to higher in-hospital mortality, extended hospital stays, and increased adverse in-hospital outcomes in patients undergoing conventional pacemaker implantation.

Long-term prognostic significance of stress hyperglycemia in patients with ST-elevation myocardial infarction

Abstract Funding Acknowledgements None. Background/aim Stress hyperglycemia is defined as hyperglycemia that occurs in critically ill patients without diabetes mellitus (DM). It is associated with adverse in-hospital outcomes in patients with ST elevation myocardial infarction (STEMI). The aim of the present study is to evaluate short- and long-term prognostic impact of stress hyperglycemia in STEMI patients. Method We analysed 2505 consecutive STEMI patients treated with successful primary PCI (pPCI) without previous DM and without cardiogenic shock at admission. Successful pPCI was defined as post-procedural flow TIMI 3. Stress hyperglycemia was defined as plasma glucose level above 7.8mmol/L at any time during hospitalization. The follow-up period was 6 years. Results Stress hyperglycemia at admission was registered in 685 (27.3%) patients. Compared with patients without stress hyperglycemia, patients with stress hyperglycemia were older and presented more often with heart failure (Killip class II and III); they were more likely to have hypertension, chronic kidney disease, three vessel coronary disease (at initial angiogram) and lower predischarge left ventricular ejection fraction (EF). In-hospital, 30-day and 6-year mortality were significantly higher in patients with stress hyperglycemia vs patients without stress hyperglycemia: 7.1% vs 1.5%, 7.5% vs 1.7% and 12.5% vs 4.6% (p&amp;lt;0.001), respectively as shown in Figure 1. In Cox regression analysis stress hyperglycemia was an independent predictor for in-hospital, 30-days and 6-year mortality- HR 2.19 (95% 1.49-3.94), p=0.018, HR 1,58(95%CI 1.15-2.85), p=0.020 and HR 1.52 (95%CI 1.32-2.17), p=0.030, respectively. Conclusion In STEMI patients without diabetes mellitus treated with successful primary PCI stress hyperglycemia is an independent predictor for short- and long-term mortality (up to 6-years). These findings emphasize the importance of close monitoring of blood glucose level in STEMI patients regardless of diabetic status.

Association Between Chronic Liver Disease and Adverse In-Hospital Outcomes in Patients Undergoing CABG: A Propensity Score-Matched Analysis

Despite a 30% decline in the rate over the last decade, coronary artery bypass graft (CABG) surgery remains a common major surgical procedure with significant morbidity and mortality. Chronic liver disease (CLD) patients, with increased survival rates due to medical advancements, are now frequently being considered for CABG, bearing higher perioperative risks. This study investigates the association between CLD and in-hospital outcomes in CABG patients using retrospective data from the National Inpatient Sample (NIS) database (2016-2020) including 7,945 CLD patients undergoing CABG that were propensity score matched with an equivalent number of patients with no CLD undergoing CABG. Clinical variables were extracted using corresponding ICD-10 codes and multivariable logistic and linear regression models were used to assess in-hospital mortality, complications, and length of stay. The overall mortality rate was 5.5% (8.6% in the CLD group with cirrhosis, 5.9% CLD group without cirrhosis, and 2.8% in the non-CLD group, p<0.001). CLD with cirrhosis was associated with higher odds of mortality (AOR= 4.21, 95% CI [3.61, 4.94]) and length of stay (β = 1.03, 95% CI [1.01, 1.05]). CLD patients with cirrhosis demonstrated higher odds of perioperative cardiac complications (cardiac arrest, ventricular arrhythmias, tamponade, and shock), thromboembolic events, gastrointestinal bleeding, bowel ischemia, acute kidney injury, pneumonia, and sepsis. This study reveals a substantial impact of CLD on adverse outcomes in CABG patients, emphasizing the need for tailored preoperative assessments and postoperative care.

Association of Left Atrial Volume Index with Adverse In-Hospital Outcome in Patients with St-Elevated Acute Myocardial Infarction

Background: Coronary heart disease is the leading cause of death worldwide, with acute STEMI being the most severe manifestation. Left atrium (LA) plays a major role in left ventricular performance. LA function is a surrogate marker of LV diastolic dysfunction. In recent past, several studies conducted in different parts in the world have focused on the effect of ASTEMI on the volume and function of left atrium. So, assessment of left atrial volume index (LAVI) by 2D echocardiography in patients who have suffered an acute STEMI helps to predict the adverse cardiovascular outcome. Objective: The aim of the study is to assess the LAVI for prediction of adverse in-hospital outcomes following acute STEMI patients admitted in a tertiary care hospital. Methods: This Hospital based prospective observational study was conducted in the department of cardiology in DMCH over 1-year period. Patients with acute STEMI admitted in the CCU of DMCH were approached for inclusion in the study. Clinical and echocardiographic parameters were collected within 48 hours of admission. LA volume is measured and then indexed to body surface area called LA volume index (LAVI) and the population was divided according to LAVI. The study comprised of 150 acute STE-MI patients and were divided into two groups, including 75 patients in each group. Patients with LAVI&gt;34 ml/m2and LAVI≤34 ml/m2 were assigned as Group I and Group II respectively &amp; followed up for adverse in-hospital outcome. All necessary information were recorded in a pretested case record form. Statistical analyses were done by SPSS 17.0. Result: The mean age was 57.7 ± 7.0 years ranging from 39 to 80 years. Most of the patients were male 109 (72.7%). Majority of the patients had anterior wall ( anterior, antero-septal &amp; extensive anterior) myocardial infarction (85%).It was observed that patients with LAVI&gt;34 ml/m2(Group I) had more adverse in-hospital outcomes than patients with LAVI≤34 ml/m2( Group II) (46.7% vs 14.7 % ;p&lt; 0.001 ).By multivariate logistic regression analysis, LAVI&gt;34 ml/m2 emerged as an independent significant predictor of adverse in-hospital outcome(Odds Ratio 6.55,95% confidence interval: 2.069 – 20.735, p = 0.001 ) Conclusion: In patients with acute STEMI, with LAVI&gt;34 ml/m2 had more adverse in-hospital outcomes than patients with LAVI≤34 ml/m2. So early assessment of LAVI by echocardiography is useful to predict adverse in-hospital outcome. Bangladesh Heart Journal 2024; 39(1): 10-16

Importance of Positive T-wave in Lead aVR and Major Adverse Cardiac Events in Patients with ST Elevation Myocardial Infarction: A Cohort Study

Introduction: It is well known that ST-Segment Elevation Myocardial Infarction (STEMI) is a significant contributor to both illness and death on a global scale. An Electrocardiogram (ECG) is an easily accessible bedside tool for diagnosing acute myocardial infarction. The T wave is usually negative in lead aVR (augmented unipolar right arm lead). However, a positive T wave in lead aVR has been shown to be associated with adverse in-hospital outcomes in patients with Acute Coronary Syndrome (ACS). Aim: To examine whether a positive T wave in lead aVR can be used as an indicator to predict Major Adverse Cardiac Events (MACE) during the hospital stay in patients with STEMI. Materials and Methods: A cohort study was performed at Shri BM Patil Medical College, Hospital and Research Centre, Vijayapura, involving patients admitted with STEMI. A total of 98 newly diagnosed ST-segment elevation patients were classified into two groups: Group A (positive T wave) in lead aVR with an amplitude of ≥ 0 mV, and Group B (negative T wave) in lead aVR with an amplitude of ≤0 mV. The hospital stays of STEMI patients were evaluated for adverse cardiac events. Chi-square test was used to assess relationships between categorical variables. Results: A total of 98 patients were evaluated, among which two were excluded. Hence, among 96 patients considered, 25 were females and 71 were male, with average ages of 57 years in Group A and 55 years in Group B. Among the 96 patients, 34 had positive T waves (35.4%) and 62 had negative T waves (64.5%) in lead aVR. The study revealed significantly higher rates of in-hospital MACE (heart failure, pulmonary oedema, and arrhythmias) in patients with positive T waves (Group A) in lead aVR, with p-values &lt;0.05, which were statistically significant. Conclusion: The present study showed that a positive T wave in lead aVR is a valuable and cost-effective tool for predicting inhospital MACE in patients with STEMI. Utilising this simple and readily available ECG measurement could support clinicians in detecting high-risk patients who require closer monitoring and more aggressive interventions, potentially leading to improved patient outcomes and resource allocation.

Acute hyperglycemia, a rabble-rouser or innocent bystander? A prospective analysis of clinical implications of acute hyperglycemia in STE-ACS patients

BackgroundAcute hyperglycemia is considered an independent prognosticator of both in-hospital and long-term outcomes in patients with acute coronary syndrome (ACS). This study aimed To analyze the incidence of acute hyperglycemia and its impact on the adverse in-hospital outcome in patients with STE-ACS undergoing primary percutaneous coronary intervention (PCI).MethodsIn this study, we enrolled patients presenting with STE-ACS and undergoing primary PCI at a tertiary care cardiac center. Acute hyperglycemia was defined as random plasma glucose (RBS) > 200 mg/dl at the time of presentation to the emergency room.ResultsOf the 4470 patients, 78.8% were males, and the mean age was 55.52 ± 11 years. In total, 39.4% (1759) were found to have acute hyperglycemia, and of these, 59% (1037) were already diagnosed with diabetes. Patients with acute hyperglycemia were observed to have a higher incidence of heart failure (8.2% vs. 5.5%; p < 0.001), contrast-induced nephropathy (10.9% vs. 7.4%; p < 0.001), and in-hospital mortality (5.7% vs. 2.5%; p < 0.001). On multivariable analysis, acute hyperglycemia was found to be an independent predictor of mortality with an adjusted odds ratio of 1.81 [1.28–2.55]. Multi-vessel disease (1.73 [1.17–2.56]), pre-procedure left ventricular end-diastolic pressure (LVEDP) (1.02 [1.0-1.03]), and Killip class III/IV (4.55 [3.09–6.71]) were found to be the additional independent predictors of in-hospital mortality.ConclusionsAcute hyperglycemia, regardless of diabetic status, is an independent predictor of in-hospital mortality among patients with STE-ACS undergoing primary PCI. Acute hyperglycemia, along with other significant predictors such as multi-vessel involvement, LVEDP, and Killip class III/IV, can be considered for the risk stratification of these patients.

Diabetes Mellitus and Its Association with Adverse In-Hospital Outcomes in Patients with COVID-19-A Nationwide Study.

Diabetes mellitus (DM) represents a relevant risk factor regarding morbidity and mortality worldwide. However, only limited data exist regarding the impact of DM on the clinical outcome of patients with COVID-19 infection. All hospitalized patients with confirmed COVID-19-infection (ICD-code U07.1) during the year 2020 in Germany were included in the present study. Patients were stratified regarding the co-prevalence of DM (ICD-codes E10-E14), and the impact of DM on in-hospital case fatality and in-hospital adverse events was analyzed. Overall, 176,137 hospitalizations with confirmed COVID-19 infection were documented; of these, 45,232 (25.7%) patients had an additional diagnosis of DM. Diabetic patients with COVID-19 were more often of male sex and 7 years older (median 76.0 (IQR: 66.0-83.0) vs. 69.0 (52.0-81.0) years, p < 0.001). COVID-19 patients with DM demonstrated an aggravated comorbidity profile, as reflected by a higher Charlson comorbidity index (6.0 (IQR: 4.0-8.0) vs. 3.0 (1.0-5.0), p < 0.001). Risk for pneumonia (OR 1.38 (95% CI: 1.35-1.41), p < 0.001), acute respiratory distress syndrome (OR 1.53 (95% CI: 1.47-1.60), p < 0.001), and need for intensive care (21.3% vs. 13.3%, p < 0.001) were increased in DM patients. DM was an independent risk factor for acute kidney failure (OR 1.49 (95% CI: 1.44-1.53), p < 0.001), dialysis (OR 1.56 (95% CI: 1.47-1.66), p < 0.001), mechanical ventilation (OR: 1.49 (95% CI: 1.43-1.56), p < 0.001), extracorporeal membrane oxygenation (OR 1.44 (95% CI: 1.27-1.62), p < 0.001), major adverse cardiac and cerebrovascular events (OR: 1.24 (95% CI: 1.20-1.27), p < 0.001), and in-hospital mortality (OR: 1.26 (95% CI: 1.22-1.30), p < 0.001). In patients with COVID-19-infection, DM is a relevant risk factor for adverse events, including mortality. The vulnerable patient group of diabetics with COVID-19 requires intense medical care and monitoring during hospitalization.

In-Hospital Outcome of Patients with ST - T Changes in Non ST Segment Elevation Myocardial Infarction

Background: This cross sectional observational study was carried out with an aim to find out in-hospital outcome in patients with ST-T changes in non-STsegment elevation myocardial infarction (NSTEMI). Methods: This cross sectional observational study was carried out in the department of cardiology, National Institute of Cardiovascular Diseases, Dhaka, Bangladesh from January 2014 to December 2014. A total of 120 patients with NSTEMI were the study population. Patients were divided into two groups on the basis of ST-T changes, 60 patients with ST-T changes were in group I and 60 patients without ST-T changes were in group II. Result: In this study, the mean age was 54.2 ±14.2 years. Male female ratio was 2.75:1 among the study population. There was no statistically significant difference in mean BMI among the two groups. Smoking was the most common risk factor present (47.5%). Smoking was found significantly more in Group I than patients of group II (p=0.02). Serum troponin I was found significantly raised in group I (42.8±5.5 vs 10.5±8.3, p=0.002). The mean left ventricular ejection fraction (LVEF) of patients in group I was significantly lower than group II (52.1±9.1% vs 61.7±6.9%. p=0.001). Adverse in-hospital outcome was significantly more in group I than group II (48.3% vs 26.7%, p=0.01). Recurrent angina pectoris, STEMI, significant arrhythmia, acute LVF and cardiogenic shock were also more in group I than in group II. In-hospital mortality was noted in group I patients with both ST segment depression and T wave inversion (6.7%). Emergency revascularization was done more commonly in patients of group I (6.7%). The mean duration of hospital stay was statistically significant between the groups (6.24±2.58 vs 4.44±1.71 days. p&lt;0.05)). Multivariate logistic regression analysis revealed that ST-T changes are an independent predictor for developing adverse inhospital outcome in patients with non-ST-segment elevation myocardial infarction. Conclusion: The ST-segment depression and T-wave inversion on admission ECG are important predictors of outcome in patients with NSTEMI. The ST-segment depression on admission ECG of patients with NSTEMI is associated with higher adverse in hospital outcome and mortality. Bangladesh Heart Journal 2022; 37(2): 99-106

1142-P: In-Hospital Hyperglycemia: An Independent Marker for In-Hospital Health Care-Associated Infection and Acute Kidney Injury in Patients with and without Known Diabetes: The DINGO Study

Objective: To investigate the relationship between hyperglycemia and adverse in-hospital outcomes in patients with and without known diabetes Research Design and Methods: The Diabetes IN-hospital: Glucose and Outcomes (DINGO) prospective cohort study was conducted over 26 weeks between Oct-20 and Mar-2020 at The Royal Melbourne Hospital. Admissions with ≥2 capillary glucose values and length of stay &amp;gt;24 hours were eligible. Stratification was by in-hospital hyperglycemia (IHH) , defined as ≥2 capillary glucose values of ≥11.1 mmol/L [≥200 mg/dL]. Results: We included 2,6admissions, of which 1,189 (46%) experienced in-hospital hyperglycemia. Following adjustment (covariates) , IHH was independently associated with in-hospital healthcare-associated infection (HAI) , acute kidney injury (AKI) , stroke, and mortality (see figure for incidence rate ratios [IRR]) . For each outcome the association was independent of diabetes status, except for mortality where the association was stronger in those without known diabetes. Patient-day mean glucose was elevated in those with HAI and AKI, on both whole-of-admission and prior-to-event calculations. Conclusions: In-hospital hyperglycemia is independently associated with in-hospital HAI and AKI in patients with and without known diabetes. Disclosure R.Barmanray: None. M.Kyi: None.

Pre-hospital delay in patients with acute myocardial infarction in China: findings from the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome (CCC-ACS) project.

OBJECTIVETo describe the duration of the pre-hospital delay time and identify factors associated with prolonged pre-hospital delay in patients with acute myocardial infarction (AMI) in China.METHODSData were collected from November 2014 to December 2019 as part of the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome (CCC-ACS) project. A total of 33,386 patients with AMI admitted to the index hospitals were included in this study. Two-level logistic regression was conducted to explore the factors associated with the pre-hospital delay and the associations between different pre-hospital delay and in-hospital outcomes.RESULTSOf the 33,386 patients with AMI, 70.7% of patients arrived at hospital ≥ 2 h after symptom onset. Old age, female, rural medical insurance, symptom onset at early dawn, and non-use of an ambulance predicted a prolonged pre-hospital delay (all P < 0.05). Hypertension and heart failure at admission were only significant in predicting a longer delay in patients with ST-segment elevation myocardial infarction (STEMI) (all P < 0.05). A pre-hospital delay of ≥ 2 h was associated with an increased risk of mortality [odds ratio (OR) = 1.36, 95% CI: 1.09–1.69, P = 0.006] and major adverse cardiovascular events (OR = 1.22, 95% CI: 1.02–1.47, P = 0.033) in patients with STEMI compared with a pre-hospital delay of < 2 h. CONCLUSIONSProlonged pre-hospital delay is associated with adverse in-hospital outcomes in patients with STEMI in China. Our study identifies that patient characteristics, symptom onset time, and type of transportation are associated with pre-hospital delay time, and provides focuses for quality improvement.

Mild renal insufficiency and attributable risk of adverse In-hospital outcomes in patients with Acute Coronary Syndrome from the improving care for Cardiovascular Disease in China (CCC) project

BackgroundRenal insufficiency (RI) is a frequent comorbidity among patients with acute coronary syndrome (ACS). We aimed to evaluate the attributable risk associated with mild RI for the in-hospital outcomes in patients with ACS.MethodsThe Improving Care for Cardiovascular Disease in China-ACS (CCC-ACS) Project was a collaborative study of the American Heart Association and the Chinese Society of Cardiology. A total of 92,509 inpatients with a discharge diagnosis of ACS were included. The attributable risk was calculated to investigate the effect of mild RI (eGFR 60-89 ml / min · 1.73 m2) on major adverse cardiovascular events (MACEs) during hospitalization.ResultsThe average age of these ACS patients was 63 years, and 73.9% were men. The proportion of patients with mild RI was 36.17%. After adjusting for other possible risk factors, mild RI was still an independent risk factor for MACEs in ACS patients. In the ACS patients, the attributable risk of eGFR 60-89ml/min·1.73m2 to MACEs was 7.78%, 4.69% of eGFR 45-59 ml/min·1.73m2, 4.46% of eGFR 30-44 ml/min·1.73m2, and 3.36% of eGFR<30 ml/min·1.73m2. ConclusionCompared with moderate to severe RI, mild RI has higher attributable risk to MACEs during hospitalization in Chinese ACS population.

The value of CHA2DS2-VASc-HS score for prediction of adverse in-hospital outcomes in patients with non-ST segment elevation myocardial infarction

For a treatment choice the early identification of non-ST myocardial infarction segment patients (NSTEMI) with poor in-hospital results is essential. The CHA2DS2-VASc-HS and CHA2DS2-VASc score was recently reported as a predictor of severity and poor outcomes in individuals with stable coronary artery disease (CAD) and acute coronary syndrome. Our research aimed at evaluating the precision of the CHA2DS2-VASc-HS score, which predicts poor outcomes in hospitals in NSTEMI patients. 120 NSTEMI patients have been enrolled. The score for CHA2DS2-VASc-HS has been computed. The participants of the research were split into two groups. Group I and Group II score 4. Patients with CHA2DS2-VASc-HS >4 were found to have higher unfavourable outcomes in the hospital than the CHA2DS2-VASc-HS score <4.

New-Onset Atrial Fibrillation and Adverse In-Hospital Outcome in Patients with Acute Pulmonary Embolism.

Atrial fibrillation (AF) can be secondary to acute pulmonary embolism (PE). This study aimed to investigate the prognostic impact of new-onset AF on patients with acute PE. In this study, 4,288 consecutive patients who were diagnosed with acute PE were retrospectively screened. In total, 77 patients with acute PE and new-onset AF were analyzed. Another 154 acute PE patients without AF were selected as the age- and sex-matched control group. Adverse in-hospital outcome comprised one of the following conditions: all-cause death, endotracheal intubation, cardiopulmonary resuscitation, and intravenous catecholamine therapy. The patients with new-onset AF had higher prevalence of congestive heart failure, higher simplified PE severity index (sPESI), higher creatinine, and larger left atrium diameter. The incidences of adverse in-hospital outcomes were 10.4 and 2.6% in patients with new-onset AF and no AF, respectively (p = 0.02). Patients with sPESI ≥ 1 had higher incidence of adverse in-hospital outcomes than those with sPESI = 0 (9.4 vs. 0.9%, p < 0.01). The area under the receiver operating characteristic curve of sPESI and sPESI + AF (adding 1 point for new-onset AF) scores in assessing the adverse in-hospital outcome were 0.80 (95% confidence interval [CI]: 0.68-0.93) and 0.84 (95% CI: 0.72-0.96), respectively. In multivariable analysis, sPESI ≥ 1 (odds ratio, 8.88; 95% CI: 1.10-72.07; p = 0.04) was an independent predictor of adverse in-hospital outcome. However, new-onset AF was not an independent predictor. In the population studied, sPESI is an independent predictor of adverse in-hospital outcomes, whereas new-onset AF following acute PE is not, but it may add predictive value to sPESI.

Impact of obesity on adverse in-hospital outcomes in patients undergoing percutaneous mitral valve edge-to-edge repair using MitraClip® procedure - Results from the German nationwide inpatient sample

Background and aimThe number of percutaneous edge-to-edge mitral regurgitation (MR) valve repairs with MitraClip® implantations increased exponentially in recent years. Studies have suggested an obesity survival paradox in patients with cardiovascular diseases. We investigated the influence of obesity on adverse in-hospital outcomes in patients with MitraClip® implantation. Methods and resultsWe analyzed data on characteristics of patients and in-hospital outcomes for all percutaneous mitral valve repairs using the edge-to-edge MitraClip®-technique in Germany 2011–2015 stratified for obesity vs. normal-weight/over-weight.The nationwide inpatient sample comprised 13,563 inpatients undergoing MitraClip® implantations. Among them, 1017 (7.5%) patients were coded with obesity. Obese patients were younger (75 vs.77 years,P < 0.001), more often female (45.4% vs.39.5%,P < 0.001), had more often heart failure (87.1% vs.79.2%,P < 0.001) and renal insufficiency (67.0% vs.56.4%,P < 0.001). Obese and non-obese patients were comparable regarding major adverse cardiac and cerebrovascular events (MACCE) and in-hospital death. The combined endpoint of cardio-pulmonary resuscitation (CPR), mechanical ventilation and death was more often reached in non-obese than in obese patients with a trend towards significance (20.6%vs.18.2%,P = 0.066). Obesity was an independent predictor of reduced events regarding the combined endpoint of CPR, mechanical ventilation and death (OR 0.75, 95%CI 0.64–0.89,P < 0.001), but not for reduced in-hospital mortality (P = 0.355) or reduced MACCE rate (P = 0.108). Obesity class III was associated with an elevated risk for pulmonary embolism (OR 5.66, 95%CI 1.35–23.77,P = 0.018). ConclusionsWe observed an obesity paradox regarding the combined endpoint of CPR, mechanical ventilation and in-hospital death in patients undergoing MitraClip® implantation, but our results failed to confirm an impact of obesity on in-hospital survival or MACCE.

Association between intravenous contrast media exposure and non-recovery from dialysis-requiring septic acute kidney injury: a nationwide observational study.

This study aimed to examine the association between the use of intravenous contrast and non-recovery from dialysis-requiring acute kidney injury (AKI-D) and in-hospital mortality among patients with sepsis. This was a retrospective observational study using the Japanese Diagnosis Procedure Combination inpatient database between January 2011 and December 2016. We identified patients with septic AKI who began continuous renal replacement therapy (RRT) within 2-days of admission and underwent computed tomography. We compared patients with AKI-D with and without the use of intravenous contrast for computed tomography and performed propensity score matching to adjust for confounders for the association between exposure to intravenous contrast and outcomes, including a composite outcome of in-hospital mortality and RRT dependence at discharge and RRT duration. From 3782 and 6619 patients with septic AKI-D with and without intravenous contrast exposure, respectively, 3485 propensity score-matched pairs were generated. No significant differences were found in the outcomes between the propensity score-matched groups: a composite outcome of in-hospital mortality and RRT dependence, 49.6% vs. 50.2% (odds ratio (OR) 0.98; 95% CI (confidence interval) 0.88, 1.07); in-hospital mortality, 45.3% vs. 46.1% (OR 0.97; 95% CI 0.87, 1.06); RRT dependence, 4.4% vs 4.1% (OR 1.08; 95% CI 0.85, 1.31); and median (interquartile range) of RRT duration, 4 [2-11]days vs. 4 [2-11]days (P = 0.58). This large observational study did not support an association between intravenous contrast media and adverse in-hospital outcomes in patients with septic AKI-D. Further studies are warranted to assess the generalizability.

442-P: Excess Burden of Adverse In-Hospital Outcomes in Patients with Diabetes Hospitalized for Stroke

Cerebrovascular accidents (CVA) represent a major complication in diabetes (DM). Real-life evidence as to whether modern management of CVA and DM have softened this relationship is currently limited. We assessed the prevalence of DM, previously known or newly-diagnosed, in all patients (N=542, males 51.5%) admitted for CVA at the Stroke Unit (SU) of Verona University Hospital from 1/1/2015 to 12/31/2016. DM was ascertained by previous diagnosis, glucose-lowering therapy at admission/discharge or admittance plasma glucose (PG) ≥11.1 mmol/L. Prevalence of DM was 21.03% (78.1% known-DM; 21.9% new-DM). In-hospital death rate was 10.5%. Compared to non-DM, patients with DM showed an increased risk of death (15.8 vs. 9.1%; OR 1.87 95% CI, 1.03-3.41) and complications (48.2 vs. 33.3%; 1.87, 1.22-2.86) with similar duration of hospitalization (mean±SEM, 9.14±1.06 vs. 8.80±0.39 days, p=0.72). All deaths occurred in the SU. The “survivors” with DM transferred to non-intensive ward had an out-of-SU hospital stay twice as longer than non-DM (2.32±1.02 vs. 0.98±0.19 days, p=0.038). After multivariable adjustment, DM remained predictor of complications (adj-OR 1.87, 1.22-2.86) but not mortality (1.79, 0.92-3.46). Patients in the highest PG quartile (≥6.55 mmol/L) displayed the highest risk of death (7.89, 2.73-22.79; PG&amp;lt;4.77 mmol/L, ref.) and complications (2.30, 1.24-4.23), independent of diabetes status, glucose-lowering medications, CVA treatment and established CVA risk factors. Individuals in the older age tertile (≥81 years) were at increased risk of death (3.25, 1.40-7.54; age &amp;lt;72 years, ref.), while risk of infectious/cardiorespiratory complications was higher at younger age (3.13, 1.42-6.9). No difference was observed in new-DM vs. known-DM. In conclusion, these data highlight that DM frequently occurs in patients admitted for CVA and adds an excess burden of adverse clinical outcomes that urgently calls for strategies to anticipate DM diagnosis in high-risk individuals.

Association of CHA2DS2-VASc-HS Score with Adverse In-hospital Outcomes in Patients with Non-ST Segment Elevation Myocardial Infarction

Background: Early detection of patients with non-ST segment elevation myocardial infarction (NSTEMI) who would suffer from adverse in-hospital outcomes is important for the therapeutic decision. Recently it was described that CHA2DS2-VASc-HS and CHA2DS2-VASc score is a predictor for severity and adverse in-hospital outcomes in patients with stable coronary artery disease (CAD) and acute coronary syndrome. The aim of our study was to assess the accuracy of the CHA2DS2-VASc-HS score predicting adverse inhospital outcomes in NSTEMI patients.&#x0D; Methods: 120 patients with NSTEMI were enrolled in this study. The CHA2DS2-VASc-HS score was calculated. The study subjects were divided into two groups. Patients’ with CHA2DS2-VASc-HS score&gt;4 were put into group I and scored” 4 into group II. They were treated as per hospital treatment protocol and followed-up for adverse in-hospital outcomes (Heart failure, cardiogenic shock, recurrent ischemic pain, significant arrhythmia and death).&#x0D; Results: It was observed that, patients with CHA2DS2-VASc-HS score &gt;4 had more adverse in-hospital outcomes than CHA2DS2-VASc-HS score d” 4 (20% vs. 3.3%, p=0.01). Group I patients developed cardiogenic shock 10%, heart failure 4%, recurrent ischemia 11.7%, significant arrhythmia 1.7% and death 1.7% than group II patients (1.7%, 3.3%, 3.3%, 0% and 0% respectively). By risk measurement, CHA2DS2-VASc-HS score &gt;4 emerged as a risk factor for developing adverse in-hospital outcome (Relative risk=6).&#x0D; Conclusion: NSTEMI patients with high CHA2DS2-VASc-HS score have more adverse in-hospital outcomes. This score, which involves only clinical parameters, can be used as a predictor of outcomes in this group of patients.&#x0D; Cardiovasc. j. 2019; 11(2): 159-166
