Reverse McConnell's: A Sign of Acute Pulmonary Embolism.

Regional right ventricular dysfunction with akinesia of the mid-free wall with normal apical motion known as McConnell's sign is an under-reported echocardiographic finding in the setting of pulmonary embolism. We conducted a literature review and systematic analysis, while describing 2 cases of pulmonary embolism with findings of reverse McConnell's sign.

Safety outcomes of sodium-glucose cotransporter-2 inhibitors in patients with type 2 diabetes and other risk factors for cardiovascular disease: a systematic review and meta-analysis.

Sodium-glucose cotransporter-2 inhibitors (SGLT2-Is) have emerged as standard therapy for heart failure. We aim to assess the safety of SGLT2-Is in patients with a high risk of cardiovascular disease. Areas covered: An electronic database search was conducted for randomized control trials comparing SGLT2-Is to placebo in patients with a high risk of cardiac disease or heart failure. Data were pooled for outcomes using random-effect models. The odds ratio (OR) and 95% confidence interval (CI) were used to compare eight safety outcomes between the two groups. The analysis included ten studies with 71 553 participants, among whom 39 053 received SGLT2-Is; 28 809 were male and 15 655 were female (mean age, 65.2 years). The mean follow-up period was 2.3 years with the range being 0.8-4.2 years. The SGLT2-Is group had a significant reduction in AKI (OR = 0.8;95% CI 0.74-0.90) and serious adverse effects (OR = 0.9; 95% CI 0.83-0.96) as compared to placebo. No difference was found in fracture (OR = 1.1; 95% CI 0.91-1.24), amputation (OR = 1.1; 95% CI 1.00-1.29), hypoglycemia (OR 0.98;95% CI 0.83-1.15), and UTI (OR = 1.1; 95% CI 1.00-1.22). In contrast, DKA (OR = 2.4; 95% CI 1.65-3.60) and volume depletion (OR = 1.2; 95% CI 1.07-1.41) were higher in SGLT2-Is group. Expert opinion/commentary: The benefits of SLGT2-Is outweigh the risk of adverse events. They may reduce the risk of AKI but are associated with an increased risk of DKA and volume depletion. Further studies are warranted to monitor a wider range of safety outcomes of SGLT2-Is.

Prediction of Recurrence of Atrial Fibrillation Post-ablation Based on Atrial Fibrosis Seen on Late Gadolinium Enhancement MRI: A Metaanalysis.

OBJECTIVES: This meta-analysis aims to investigate the recurrence of atrial fibrillation (AF) post-ablation based on the various stages of fibrosis seen in the late gadolinium enhancement magnetic resonance imaging (LGE-MRI). METHODS: Electronic databases were searched using specific terms and identified nine studies that met the inclusion criteria. A total of 1,787 patients underwent LGE-MRI to assess atrial fibrosis before catheter ablation for AF. We performed three analyses: first, we compared stage IV versus stage I (reference group). The second set examined the combined stages III and IV versus stages I and II (reference group). The third set compared stage IV versus combined stages I, II, and III. The metanalysis relied on a random-effects model to pool the odds ratios (OR) and 95% confidence intervals (CI) using the DerSimonian and Laird method. The data was analyzed using StatsDirect software in England. RESULTS: The study showed a higher rate of AF recurrence after ablation in stage IV atrial fibrosis than in stage I (OR, 9.54; 95% CI, 3.81 to 28.89; P<00001). Also, in patients with combined stages III & IV of atrial fibrosis, AF recurrence was significantly higher after ablation than in stages I & II groups (OR, 2.37; 95% CI, 1.61 to 3.50; P<00001). Similarly, compared to combined stages I, II, and III, patients with stage IV have higher odds of recurrence post-ablation (OR, 4.24; 95% CI, 2.39- 7.52, P < 0.001). CONCLUSION: This metanalysis demonstrates the strong association between left atrial fibrosis in LGE-MRI and AF post-ablation recurrence. The finding of this study will further assist clinicians in predicting the recurrence rate of AF based on the amount of fibrosis and tailor therapeutic decisions for further management.

Association of Sodium-Glucose Cotransporter 2 Inhibitors With Cardiovascular Outcomes in Patients With Type 2 Diabetes and Other Risk Factors for Cardiovascular Disease: A Meta-analysis.

Importance: The cardiovascular outcome in selected populations when sodium-glucose cotransporter 2 inhibitors (SGLT2-Is) are emerging as standard therapy is not clearly understood. It is important to learn the magnitude of cardiovascular benefit using SGLT2-Is across the select subgroups that include both sexes and multiple age and racial and ethnic groups. Objectives: To evaluate the association between use of SGLT2-Is and cardiovascular benefits in a prespecified group in a larger sample size using data obtained from randomized clinical trials. Data Sources: Search of electronic databases PubMed, Google Scholar, Web of Science, and Cochrane from inception to January 10, 2021, with additional studies identified through conference papers and meeting presentations, ClinicalTrials.gov, and reference lists of published studies. Study Selection: Placebo-controlled randomized clinical trials in which participants had atherosclerotic cardiovascular disease (ASCVD) or risk factors for ASCVD, diabetes, or heart failure and which reported the primary outcome were included in this study. Multicenter observational and nonobservational studies and those with different outcomes of interest were excluded. Data Extraction and Synthesis: Medical Subject Heading search terms included SGLT2-I and multiple cardiovascular outcomes in different combinations. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. The analysis of all outcomes was performed using a Mantel-Haenszel equation and the random-effects model. Main Outcomes and Measures: Six efficacy outcomes of SGLT2-I use (cardiovascular death and hospitalization for heart failure [HHF] as the primary outcome and major adverse cardiovascular event, HHF, cardiovascular death, acute myocardial infarction, and all-cause mortality as secondary outcomes), were evaluated. Subgroup analysis was performed for the primary outcome of cardiovascular death or HHF. Odds ratios (ORs) and 95% CIs were used to compare 2 interventions. Results: Ten studies with 71 553 participants were included, among whom 39 053 received SGLT2-Is; among studies that reported these data, 28 809 were men and 15 655 were women (mean age, 65.2 [range, 61.9-70.0] years). Race and ethnicity were defined in the original trials and were categorized as Asian, Black, or other (6900 participants) and White (26 646 participants) for the purposes of this analysis (the category "other" was not specified consistently). In terms of age, 16 793 were younger than 65 years and 17 087 were 65 years or older. At a mean follow-up 2.3 (range, 0.8-4.2) years, the SGLT2-I group favored reduction in primary outcome (3165 of 39 053 [8.10%] vs 3756 of 32 500 [11.56%]; OR, 0.67 [95% CI, 0.55-0.80]; P < .001). No difference was noted in the rate of acute myocardial infarction compared with the placebo group (1256 of 26 931 [4.66%] vs 958 of 20 373 [4.70%]; OR, 0.95 [95% CI, 0.87-1.03]; P = .22). Subgroup analysis favored SGLT2-I use for the primary outcome in both sexes, age groups, and racial and ethnic groups. Conclusions and Relevance: This meta-analysis supports that SGLT2-Is have emerged as an effective class of drugs for improving cardiovascular morbidity and mortality in selected patients. Sodium-glucose cotransporter 2 inhibitors were not associated with reduced risk of acute myocardial infarction. Future long-term prospective studies are warranted to understand the long-term cardiovascular benefits.

An assessment of race and gender-based biases among readmission predicting tools (HOSPITAL, LACE, and RAHF) in heart failure population.

BACKGROUND: The objective of our study is to retrospectively investigate if the HOSPITAL score, LACE index, and RAHF scale exhibit any bias based on gender and race in heart failure readmissions. METHODS: This is a retrospective cohort study with all adult medical patients discharged with congestive heart failure from 2016 to 2018 from Southern Illinois University School of Medicine Hospitalist service. The receiver operating characteristic (ROC) curve was constructed comparing prediction tools (HOSPITAL score, LACE index, and RAHF scale) performance based on gender and race by measuring the area under the curve (AUC). Absolute Between-ROC Area (ABROCA) values were calculated. All statistical analyses were performed using R version 3.6.2. RESULTS: The performance of the HOSPITAL score in the majority and minority population showed a statistically significant difference between AUCs (0.714 and 0.633, p = 0.029) and an ABROCA of 0.081 indicating superior performance in predicting hospital readmissions in the majority group vs. the minority. The performance of RAHF score in females and males showed statistically significant differences between AUCs (0.567 and 0.527, p = 0.04) and an ABROCA of 0.04 indicating the superior performance of the RAHF score in females compared with males. CONCLUSIONS: Our study demonstrated that the HOSPITAL score and the RAHF scale showed significant differences in predicting 30-day readmissions risk based on race and gender, respectively, in heart failure patients, whereas the LACE index did not show any significant difference.

Outcomes of Cardiogenic Shock With Autoimmune Rheumatological Disorders.

AIMS: Data on cardiogenic shock (CS) in autoimmune diseases (AID) is limited. Our study aims to evaluate in-hospital outcomes of CS in hospitalized patients with underlying AID compared with patients without AID. METHODS: The National Inpatient Sample (NIS) database years 2011-17 was used to identify hospitalizations for CS. We retrospectively compared in-hospital outcomes of CS in patients with underlying AID versus non-AID. RESULTS: Of 863,239 patients diagnosed with CS, 23,127 (2.7%) had underlying AID. The AID population was older with more women and African American patients (P < 0.001 for all). There was a significant increase in in-hospital mortality in patients with AID vs non-AID that persisted after adjustment for demographics, comorbidities, insurance, socioeconomic status and hospital characteristics (38.3% vs 36.3%, aOR 1.06; 95% CI: 1.02-1.09, P = 0.001). Patients with AID had a lower rate of respiratory complications (11.5% vs 13.1%), acute stroke (6.0% vs 6.8%), use of mechanical circulatory support (12.0% vs 14.5%) and discharge to an outside facility (29.1% vs 28.8%) (P ≤ 0.001 for all). Using multivariable logistic regression, we identified female gender, Native American ethnicity, heart failure, coagulopathy, pulmonary circulation disorders, metastatic cancer, and fluid and electrolytes disorders as independent predictors of mortality in patients with AID who were diagnosed with CS. CONCLUSION: Patients with AID hospitalized with CS have increased mortality which may be related to their underlying disease process and lack of effective disease-directed therapy for CS related to AID.

Social Vulnerability Indices as a Risk Factor for Heart Failure Readmissions.

Objectives: The objective of our study was to use the parameters of social vulnerability index (SVI) to observe their association with the 30-day hospital readmissions in the heart failure population.Methods: Data required for analysis were extracted from the electronic medical record. The geographic SVI data was then merged with the clinical data. Qualitative variables and reported as frequency and quantitative variables and reported as the mean ± standard deviation. Variables from univariate analysis with a P value of ≤ 0.10 were evaluated using multivariate logistic regression with stepwise backward variable selection and receiver operating curve (ROC) analysis.Results: The odds ratio of readmission predicted by HOSPITAL score was 1.137 (P value = 0.004, 95% CI = 1.041-1.241). SVI parameter recording disability showed odds ratio of 1.521 (P value = 0.006, 95% CI = 1.125-2.058) and SVI parameter tracking vehicle ownership showed odds ratio of 15.355 (P value = 0.014, 95% CI = 1.755 - 134.383). The ROCs were generated for three scenarios: (i) HOSPITAL score only which had area under the curve (AUC) of 0.702 (P value = 0.015), (ii) SVI indicators tracking vehicle ownership and disability resulted in the AUC of 0.589 (P value = 0.016), and (iii) all of the above combined increased the AUC increased to 0.718 (P value = 0.015).Conclusions: Two social parameters (limited vehicle access and prevalence of disability) from the SVI showed a strong association with 30-day hospital readmissions.

Comprehensive evaluation of cardiovascular efficacy and safety outcomes of SGLT2 inhibitors in high risk patients of cardiovascular disease: systematic review and meta-analysis.

OBJECTIVES: To demonstrate a magnitude of the cardiovascular benefits, concomitantly analyzing the safety outcomes of sodium-glucose cotransporter 2 inhibitor (SGLT2-I) comprehensively, as a class effect in a larger sample size combined from recent randomized control trials. METHODS: We searched electronic databases using specific terms and evaluated 6 efficacy and 10 safety outcomes. Odds ratios (ORs) and 95% confidence interval (CI) were used to compare two interventions. RESULTS: Five studies (n = 41 267) were included, among which 23 539 received SGLT2-I. The SGLT2-I group favored reduction in major adverse cardiovascular events (OR, 0.78; 95% CI, 0.62-0.98; P = 0.03), cardiovascular death (CVD) or heart failure hospitalization (OR, 0.60; 95% CI, 0.46-0.80; P = 0.0004), rate of hospitalization for heart failure (OR, 0.56; 95% CI, 0.44-0.72; P < 0.00001), CVD (OR, 0.68; 95% CI, 0.50-0.93; P = 0.01), all-cause mortality (OR, 0.67; 95% CI, 0.48-0.93; P = 0.02) and myocardial infarction (OR, 0.79; 95% CI, 0.64-0.99; P = 0.04) when compared to the placebo group. Safety analysis showed higher diabetic ketoacidosis (DKA) rate in SGLT2-I group (OR, 2.33; 95% CI, 1.40-3.90; P = 0.001); in contrast, major hypoglycemic events were significantly lower (OR, 0.79; 95% CI, 0.73-0.87; P < 0.00001). AKI was significantly higher in the placebo group (OR, 0.76; 95% CI, 0.65-0.88; P = 0.0004). There were no statistically significant effects on other outcomes. CONCLUSION: In selected high-risk patients of cardiovascular disease, the SGLT2-I is a potential effective class of drugs for improving cardiovascular outcomes and all-cause mortality without an increased risk of all other major complications except DKA on this meta-analysis.

Impact of chronic kidney disease on in-hospital outcomes and readmission rate after edge-to-edge transcatheter mitral valve repair.

BACKGROUND: Transcatheter mitral valve repair (TMVR) is a treatment option for patients with 3+ or greater mitral regurgitation who cannot undergo mitral valve surgery. Outcomes in patients with chronic kidney disease (CKD) and end stage renal disease (ESRD) are unclear. We sought to evaluate the TMVR in-hospital outcomes, readmission rates and its impact on kidney function. METHODS: Data from 2016 National Readmission Database was used to obtain all patients who underwent TMVR. Patients were classified by their CKD status: no CKD, CKD, or ESRD. The primary outcomes were: in-hospital mortality, 30- and 90-day readmission rate, and change in CKD status on readmission. Multivariable logistic regression analysis was used to assess in-hospital, readmission outcomes and kidney function stage. RESULTS: A total of 4,645 patients were assessed (mean age 78.5 ± 10.3 years). In-hospital mortality was higher in patients with CKD (4.0%, odds ratio [OR]:2.01 [95% CI, confidence interval: 1.27-3.18]) and ESRD (6.6%, OR: 6.38 [95% CI: 1.49-27.36]) compared with non-CKD (2.4%). 30-day readmission rate was higher in ESRD versus non-CKD patients (17.8% vs. 10.4%, OR: 2.24 [95% CI: 1.30-3.87]) as was 90-day readmission (41.2% vs. 21% OR: 2.51 [95% CI:1.70-3.72]). Kidney function improved in 25% of patients with CKD stage 3 and in 50% with CKD stage 4-5 at 30-and 90-day readmission. Incidence of AKI, major bleeding, and respiratory failure were higher in CKD group. CONCLUSIONS: Patients with CKD and ESRD have worse outcomes and higher readmission rate after TMVR. In patients who were readmitted after TMVR, renal function improved in some patients, suggesting that TMVR could potentially improve CKD stage.

Comprehensive Outcomes Evaluation After Percutaneous Coronary Intervention in Stable Ischemic Heart Disease and Acute Coronary Syndrome for Short- Versus Standard-Term Dual Antiplatelet Therapy: A Systematic Review and Meta-analysis of Randomized Control Trials.

Newer generation drug eluting stents (DES) and pharmacotherapy have decreased thrombotic events post-percutaneous coronary intervention (PCI). There is lack of wide-ranging safety and efficacy evaluation in both stable ischemic heart disease and acute coronary syndrome in short-term (3-6 months) versus Standard-term (12 months) dual antiplatelet therapy (DAPT). We searched electronic databases using specific terms to identify randomized control trials comparing different durations of DAPT after PCI with DES. The outcomes of interest included all-cause mortality, myocardial infarction, stent thrombosis, major bleeding, target lesion and vessel revascularization, and stroke at follow-up duration ≥12 months post index PCI. Studies that compared DAPT <3 months or DAPT ≥12 months were excluded. Thirteen randomized control trials (n = 31,831) were included; 8401 patients received DAPT for 3 months and 7482 patients received DAPT in the 6 months group. Major bleeding rate was lower in the short-term (3-6 months) versus Standard-term (12 months) group (risk ratio 0.66; 95% confidence interval, 0.52-0.84, P < 0.05). Repeat revascularization rate was higher in the short-term (3-6 months) versus Standard-term (12 months) (risk ratio 1.17; 95% confidence interval, 1.01-1.36, P < 0.05) of DAPT duration after PCI with DES. No difference in other outcomes were observed when comparing short versus standard duration of DAPT in both stable ischemic heart disease and acute coronary syndrome.

Complete Versus Culprit-Only Revascularization in Patients Presenting With ST-Segment Elevation Myocardial Infarction: A Meta-Analysis of Randomized Control Trials.

BACKGROUND: In patients with ST elevation myocardial infarction (STEMI), primary percutaneous coronary intervention (PCI) of the culprit vessel is the preferred treatment option. For patients with multivessel disease, the benefit of revascularization of the non-culprit artery is not well known. This meta-analysis aims to assess the efficacy and safety of complete versus culprit vessel only revascularization. METHODS: Randomized control trials (RCT) that compared head-to-head complete versus culprit-vessel only revascularization in STEMI patients and reported main outcomes of interest such as mortality, myocardial infarction, and revascularization, were included in this meta-analysis. RESULTS: We found ten RCTs satisfying our inclusion criteria. Data was extracted and used to estimate the risk ratio (RR) and 95% confidence interval (CI) for dichotomous variables. Our study included 7030 patients (3426 complete revascularization, and 3604 culprit-only revascularization). Complete revascularization (CR) (both immediate and staged) significantly reduced the risk of MACE compared with culprit only (CO) revascularization (10.7% vs 20.1%, RR 0.53; 95% CI 0.43 to 0.64; P < 0.0001), reinfarction (5.0% vs 6.9%, RR 0.69; 95 CI 0.51 to 0.93; P < 0.01), and revascularization (4.2% vs 12.7%, RR 0.37; 95 CI 0.26 to 0.54; P < 0.0001). Our analysis did not find any significant difference in all-cause mortality between CR and CO (4.6% vs 5.0%, RR 0.89; 95 CI 0.72 to 0.1.10; P = 0.27). CONCLUSION: In conclusion, complete revascularization was associated with a significant reduction in major adverse cardiovascular events, revascularization and reinfarction.

Heart Failure Drug Class Effects on 30-Day Readmission Rates in Patients with Heart Failure with Preserved Ejection Fraction: A Retrospective Single Center Study.

Background: The pharmacologic management of heart failure with preserved ejection fraction (HFpEF) involves far fewer options with demonstrated additional benefit. Therefore, we examined the effect of combination of multiple classes of HF medication in the 30-day hospital readmission in patients with HFpEF. Methods: All adult patients discharged with a diagnosis of HFpEF and a left ventricular ejection fraction (LVEF) of ≥ 50% reported during the admission or within the previous six months from our institution were retrospectively studied for a 30-day hospital readmission risk. Individual as well as combination drug therapy at the time of hospital discharge were evaluated using Pearson chi2 test and multivariate logistic regression. Results: The overall 30-day readmission rate in this HFpEF cohort of 445 discharges was 29%. Therapy with loop diuretics (p = 0.011), loop diuretics and angiotensin receptor blocker (p = 0.043) and loop diuretics and beta blockers (p = 0.049) were associated with a lower risk of 30-day hospital readmission. Multivariate logistic regression revealed only loop diuretics to be associated with a lower risk of hospital readmission in patients with HFpEF (OR 0.59; 95% CI, 0.39-0.90; p = 0.013). Conclusions: Our study revealed that loop diuretics at discharge decreases early readmission in patients with HFpEF. Further, our study highlights the implication of a lack of guidelines and treatment challenges in HFpEF patients and emphasizes the importance of a conservative approach in preventing early readmission in patients with HFpEF.

Heart Failure with Preserved Ejection Fraction and 30-Day Readmission.

OBJECTIVE: Several studies identify heart failure (HF) as a potential risk for hospital readmission; however, studies on predictability of heart failure readmission is limited. The objective of this work was to investigate whether a specific type of heart failure (HFpEF or HFrEF) has a higher association to the rate of 30-day hospital readmission and compare their predictability with the two risk scores: HOSPITAL score and LACE index. DESIGN: Retrospective study from single academic center. METHODS: Sample size included adult patients from an academic hospital in a two-year period (2015 - 2017). Exclusion criteria included death, transfer to another hospital, and unadvised leave from hospital. Baseline characteristics, diagnosis-related group, and ICD diagnosis codes were obtained. Variables affecting HOSPITAL score and LACE index and types of heart failure present were also extracted. Qualitative variables were compared using Pearson chi2 or Fisher's exact test (reported as frequency) and quantitative variables using non-parametric Mann-Whitney U test (reported as mean ± standard deviation). Variables from univariate analysis with P values of 0.05 or less were further analyzed using multivariate logistic regression. Odds ratio was used to measure potential risk. RESULTS: The sample size of adult patients in the study period was 1,916. All eligible cohort of patients who were readmitted were analyzed. Cumulative score indicators of HOSPITAL Score, LACE index (including the Charlson Comorbidity Index) predicted 30-day readmissions with P values of <0.001. The P value of HFpEF was found to be significant in the readmitted group (P < 0.001) compared to HFrEF (P = 0.141). Multivariate logistic regression further demonstrated the association of HFpEF with higher risk of readmission with odds ratio of 1.77 (95% CI: 1.25 - 2.50) and P value of 0.001. CONCLUSIONS: Our data from an academic tertiary care center supports HFpEF as an independent risk factor for readmission. Multidisciplinary management of HFpEF may be an important target for interventions to reduce hospital readmissions.

Clinical outcomes of adjunctive posterior wall isolation in persistent atrial fibrillation: A meta-analysis.

BACKGROUND: Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation but the recurrence rate remains relatively high in persistent patients with AF. Therefore, posterior wall isolation (PWI) in addition to PVI has been proposed to increase freedom from AF. OBJECTIVE: To evaluate the success of adjunctive PWI in persistent AF. METHODS: We searched electronic database using specific terms. The primary outcomes are recurrence rate of AF and recurrence of atrial arrhythmias. The secondary outcomes were atrial flutter/tachycardia (AFL/AT), procedure time, fluoroscopy time, and procedure related complications. Estimated risk ratios (RRs) and 95% confidence intervals (CIs) were evaluated. RESULTS: Six studies were included (1334 patients with persistent AF). Adjunctive PWI resulted in a significant reduction in the recurrence rate of AF compared with patients who had PVI only (19.8% vs 29.1%; RR, 0.64; 95% CI, 0.42-0.97; P < .04; I2 = 76%). There was a significant reduction in the recurrence rate of all atrial arrhythmia (30.8% vs 41.1%; RR, 0.75; 95% CI, 0.60-0.94; P < .01; I2 = 60%). Compared with PVI only, adjunctive PWI did not increase the rate of AFL or AT (11.6% vs 13.9%; RR, 0.85; 95% CI, 0.54-1.32; P < .46; I2 = 47%) or the rate of procedure related complications (4.6% vs 3.6%; RR, 1.25; 95% CI, 0.72-2.17; P < .44; I2 = 0%). CONCLUSION: In patients with persistent AF, adjunctive PWI was associated with decreased recurrence of AF and atrial arrhythmias compared with PVI alone without an increased risk of AFL or AT or procedure related complications.

Echocardiographic Derived Parameters Association With Long-Term Outcomes After Transcatheter Valve Replacement.

BACKGROUND: Transaortic flow, maximum velocity (V max), mean gradient (MG), left ventricular ejection fraction (LVEF), Aortic valve area (AVA) and dimensional index (DI) are important determinants of prognosis in patients with severe aortic stenosis. The specific role of these echocardiography-derived values in predicting prognosis of severe aortic stenosis patients undergoing Transcatheter aortic valve replacement (TAVR) is less defined. METHODS: We identified all severe AS patients who underwent TAVR between 01/2012 and 6/2016. Baseline characteristics, clinical, procedural and one year follow-up data were obtained. Hierarchical logistic regression was used to assess predictors of 1-year mortality after TAVR. Normal flow (NF) was defined as having stroke volume index (SVI) of ≥35 ml/m2; while low Flow (LF) was defined as SVI < 35 ml/m2. High gradient (HG) was defined as mean gradient of ≥40 mmHg; while low gradient (LG) was defined as <40 mmHg. RESULTS: A total of 399 patients were analyzed. There were no significant differences in baseline characteristics. LVEF less than 35% was associated with higher rate of 1-year mortality (17.6% LVEF <35% vs. 8.9% LVEF≥35%; RR = 2.19; CI 1.05 to 4.54; P = 0.03). There was no difference in 1-year mortality outcomes after TAVR in relation to: Mean Gradient MG, transaortic flow/Stroke Volume Index SVI, DI, V max or AVA. CONCLUSION: Low LVEF <35% remains the strongest parameter associated with 1 year mortality after TAVR.

HOSPITAL Score, LACE Index and LACE+ Index as predictors of 30-day readmission in patients with heart failure.

This study aimed to evaluate the accuracy of the HOSPITAL Score (Haemoglobin level at discharge, Oncology at discharge, Sodium level at discharge, Procedure during hospitalization, Index admission, number of hospital admissions, Length of stay) LACE index (Length of stay, Acute/emergent admission, Charlson comorbidy index score, Emerency department visits in previous 6 months) and LACE+ index in predicting 30-day readmission in patients with diastolic dysfunction. Heart failure remains one of the most common hospital readmissions in adults, leading to significant morbidity and mortality. Different models have been used to predict 30-day hospital readmissions. All adult medical patients discharged from the SIU School of Medicine Hospitalist service from 12 June 2016 to 12 June 2018 with an International Classification of Disease, 10th Revision, Clinical Modification diagnosis of diastolic heart failure were studied retrospectively to evaluate the performance of the HOSPITAL Score, LACE index and LACE+ index readmission risk prediction tools in this patient population. Of the 730 patient discharges with a diagnosis of heart failure with preserved ejection fraction (HFpEF), 692 discharges met the inclusion criteria. Of these discharges, 189 (27%) were readmitted to the same hospital within 30 days. A receiver operating characteristic evaluation showed C-statistic values to be 0.595 (95% CI 0.549 to 0.641) for the HOSPITAL Score, 0.551 (95% CI 0.503 to 0.598) for the LACE index and 0.568 (95% CI 0.522 to 0.615) for the LACE+ index, indicating poor specificity in predicting 30-day readmission. The result of this study demonstrates that the HOSPITAL Score, LACE index and LACE+ index are not effective predictors of 30-day readmission for patients with HFpEF. Further analysis and development of new prediction models are needed to better estimate the 30-day readmission rates in this patient population.

A Rare Case of Isolated and Idiopathic Spontaneous Renal Artery Dissection in a Female Patient on Multiple Medications.

Constituting less than 25% of all renal artery dissections (RAD), isolated spontaneous renal artery dissection (SRAD) is a rare diagnosis that can cause subsequent renal infarction with impairment. The majority of SRAD cases are idiopathic. Management ranges from conservative, medical to endovascular, and surgical repair. We report a case of a young female on multiple medications who presented with SRAD. She presented with acute abdominal pain and was found to have isolated spontaneous renal artery dissection. The etiology of this patient's isolated SRAD could possibly be pinned down to her multiple stimulant medications used after the major known causes were ruled out.

Predictors of 30-day hospital readmission: The direct comparison of number of discharge medications to the HOSPITAL score and LACE index.

Effective hospital readmission risk prediction tools exist, but do not identify actionable items that could be modified to reduce the risk of readmission. Polypharmacy has attracted attention as a potentially modifiable risk factor for readmission, showing promise in a retrospective study. Polypharmacy is a very complex issue, reflecting comorbidities and healthcare resource utilisation patterns. This investigation compares the predictive ability of polypharmacy alone to the validated HOSPITAL score and LACE index readmission risk assessment tools for all adult admissions to an academic hospitalist service at a moderate sized university-affiliated hospital in the American Midwest over a 2-year period. These results indicate that the number of discharge medications alone is not a useful tool in identifying patients at high risk of hospital readmission within 30 days of discharge. Further research is needed to explore the impact of polypharmacy as a risk predictor for hospital readmission.

Vital Sign Abnormalities on Discharge Do Not Predict 30-Day Readmission.

OBJECTIVE: Hospital readmissions are common and expensive. Risk factors for hospital readmission may include vital sign abnormalities (VSA) at the time of discharge. The study aimed to validate VSA at the time of discharge as a useful predictor of hospital readmission within 30 days of discharge. VSA was compared to the validated HOSPITAL score and LACE index readmission risk prediction models. DESIGN: All adult medical patients discharged from internal medicine hospitalist service were studied retrospectively. Variables such as age, gender, diagnoses, vital signs at discharge, 30-day hospital readmission, and components for the HOSPITAL score and LACE index were extracted from the electronic health record for analysis. SETTINGS: A 507-bed university-affiliated tertiary care center. PARTICIPANTS: During the 2-year study period, a cohort of 1,916 discharges for the hospitalist service were evaluated. The final analysis was based on the data from 1,781 hospital discharges that met the inclusion criteria. RESULTS: VSA was found in 13% of the study population. Only one abnormal vital sign was present in a higher proportion readmitted to the hospital within 30 days of discharge. No discharges had three or more unstable vital signs. Receiver operating characteristic (ROC) comparisons of the HOSPITAL score (C statistic of 0.67, P < 0.001), LACE index (C statistic of 0.61, P < 0.001), and VSA (C statistic of 0.52, P = 0.318) indicated that VSA at time of discharge was not a useful predictor of hospital readmission within 30 days of discharge. CONCLUSION: Our study indicated that VSA at the time of discharge is not a useful predictor of 30-day hospital readmission at a university-affiliated teaching hospital. The more complex and validated HOSPITAL score and LACE index were useful predictors of hospital readmission in this patient population.

Nivolumab-Associated Acute Demyelinating Encephalitis: A Case Report and Literature Review.

Nivolumab is a checkpoint inhibiting immunotherapeutic agent prescribed for the treatment of resistant cancers. Many immune-related adverse effects including neurological effects have been described, but central nervous system (CNS) toxicities are rarely reported. We present a 59-year-old Caucasian woman with a history of treatment-resistant, progressive, laryngeal squamous cell carcinoma. She received nivolumab and presented with gradual weakness, confusion, and progressive dyspnea. Magnetic resonance imaging of the head showed multifocal cerebral demyelination, primarily involving the parietal lobe. The diagnosis of acute demyelinating encephalitis was made. She improved dramatically after stopping nivolumab and receiving treatment with high-dose intravenous steroid and immunoglobin therapy. We conclude, from this case and literature review, that immune checkpoint inhibitor treatment requires more investigation to determine if autoimmune encephalitis with demyelination can occur as a severe form of immune-related adverse events. CNS toxicity appears to be reversible with prompt cessation of immunotherapy followed by treatment with high doses of steroid with or without intravenous immunoglobulin therapy.
