Cardiogenic shock in autoimmune rheumatologic diseases: an insight on etiologies, management, and treatment outcomes.

Autoimmune rheumatological disorders are known to have an increased risk for cardiovascular diseases including coronary artery disease (CAD), myocarditis, pericarditis, valvulopathy, and in consequence cardiogenic shock. Data on cardiogenic shock in rheumatological diseases are scarce; however, several reports have highlighted this specific entity. We sought to review the available literature and highlight major outcomes and the management approaches in each disease. Systematic literature search, including PubMed, Ovid/Medline, Cochrane Library, and Web of Science, was conducted between January 2000 and December 2009. We reviewed all cases reporting cardiogenic shock with rheumatologic conditions, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), Takayasu's arteritis (TA), granulomatosis with polyangiitis (GPA), giant cell arteritis (GCA), and antiphospholipid syndrome (APS). We selected 45 papers reporting a total of 48 cases. Mean age was 39 ± 7.3 years and 68.8% were females. Most common rheumatologic conditions associated with cardiogenic shock were SLE (31%), GPA (23%), TA (14.6%), APA (10.4%), and RA (8.3%). Cardiogenic shock was found to be caused by eosinophilic myocarditis in 58% of cases, CAD in 19% of cases, and valvulopathy in 6% of cases. Most patient required high-dose steroids and second immunosuppressant therapy. Mechanical circulatory supported was required in 23 cases, IABP in 16 cases, and ECMO in 12 cases. Complete recovery occurred in 37 patients while 9 patients died and 2 required heart transplant. Responsible for two-thirds of cases, eosinophilic myocarditis should be suspected in young cardiogenic shock patients with underlying rheumatologic conditions. Lupus and GPA are the two most common conditions.

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.

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.

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.

Interstitial Fibrosis and Arrhythmic Mitral Valve Prolapse: Unravelling Sex-Based Differences.

Background: Interstitial fibrosis as quantified by cardiac magnetic resonance (CMR) has been demonstrated in arrhythmic mitral valve prolapse (MVP), a condition with known female predominance. However, prior studies included only MVP cases with significant mitral regurgitation (MR) or mitral annular disjunction (MAD). We sought to evaluate the association between interstitial fibrosis and complex ventricular ectopy (ComVE) in MVPs unselected for MAD or severe MR, and to investigate the contribution of sex to this association. Methods: We performed contrast CMR in consecutive individuals with MVP between 2020 and 2022. Extracellular volume fraction (ECV%), a surrogate marker for interstitial fibrosis, was quantified using T 1 mapping. Replacement fibrosis was assessed using late gadolinium enhancement (LGE). ComVE, defined as frequent premature ventricular contractions and/or non-sustained/sustained ventricular tachycardia (VT), was detected using ambulatory ECG monitoring. Results: We identified 59 MVP cases without severe MR (49% women, 80% with mild or less MR) and available ECV% measurement. Among these, 23 (39%) had ComVE, including a case of aborted ventricular fibrillation (VF) and one with sudden arrhythmic death, both females. Global ECV% was significantly greater in ComVE versus non-ComVE (31%[27-33] vs 27%[23-30], p=0.002). In MVP-ComVE, higher segmental ECV% was not limited to the inferolateral/inferior LV wall, but was also demonstrated in atypical segments including the anterior/anterolateral wall (p<0.05). The association between ComVE and ECV% was driven by female sex (32%[30-33] vs 28%[26-30], p=0.003 in females; 31%[25-33] vs 26%[23-30], p=0.22 in males). ECV% remained independently associated with an increased risk of ComVE, including VT/VF, after adjustment for cardiovascular risk factors, MAD, and LGE (p<0.01). Conclusion: In MVP without significant MR, interstitial fibrosis by CMR is associated with an increased risk of ComVE, suggesting a primary myopathic process. The stronger association between interstitial fibrosis and ComVE in females may explain why severe arrhythmic complications are more prevalent among women.

National Trends of Percutaneous Mechanical Support Utilization During Percutaneous Coronary Interventions in Chronic Total Occlusion.

Coronary chronic total occlusion (CTO) is common in patients with multivessel coronary artery disease. Percutaneous coronary artery (PCI) interventions have shown favorable outcomes in patients with CTO. Nevertheless, the data regarding the utilization of mechanical circulatory support in CTO PCIs is not well established. We sought to investigate the trends in utilization and periprocedural complications in this population. Using the National Inpatient Sample database from 2011 to 2019, we identified patients diagnosed with CTO who underwent PCI. We investigated the presence of a linear trend in the utilization of mechanical circulatory support (MCS) during those procedures and the associated periprocedural complications using the Cochran-Armitage method. A total of 208,123 patients who were diagnosed with CTO and underwent PCI from 2011 to 2019, of which in 6,319 patients MCS was used during the procedure. Patients in the MCS group were older (67.4 vs 66.4 years), less likely to be women (24.0% vs 26.4%), and equally likely to be African-American (9.4% vs 8.8%) with a higher burden of co-morbidities in terms of coronary artery disease, congestive heart failure, and atrial fibrillation (p <0.001 for all). Using the Cochrane-Armitage method, we found a statistically significant linear uptrend in the utilization of MCS from 269 (1.4%) to 990 cases (7.0%) from 2011 to 2019. Using multivariable logistic regression, female gender, renal failure, alcohol abuse, coagulopathy, and fluid and electrolyte disorders were identified as independent predictors of mortality in CTO PCI procedures assisted with MCS (p ≤0.007). In conclusion, the utilization of MCS in CTO PCI procedures has been increasing over the years. Female gender and renal failure are independently associated with a higher mortality risk.

COVID-19: The Impact on Internal Medicine Resident Training.

The novel coronavirus disease 2019 (COVID-19) pandemic has impacted the lives of physicians at all levels. The workloads and working hours have increased tremendously which affected the time spent on administrative and academic duties. The COVID-19 pandemic imposed a lot of challenges on academic institutions in term of providing quality of care to patients and maintaining the quality of education for trainee. Herein, we discuss the challenges and impact of the pandemic on residents training.

Loperamide-Induced Ventricular Tachycardia Storm.

Loperamide is an over-the-counter antilaxative medication with minor opioid properties. For this reason, it has recently become a drug of concern for the Food and Drug Administration due to its potential for abuse. In addition, further apprehension pertaining to its over-the-counter availability has developed due to the recent increase in reported cases of loperamide overdose or prolonged use leading to arrhythmias. We described a rare case of loperamide-induced ventricular tachycardia storm.

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.

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.

USMLE step 1 pass/fail: The impact on international medical graduates.

On February 12th, 2020, and after a yearlong discussion, the National Board of Medical Examiners (NBME) announced that the reporting of the U.S. Medical Licensing Examination (USMLE) step one exam will transition to pass/fail reporting system and is expected to kick in as early as 2022. The decision was met with various responses, especially by the IMG community. In this paper, we discuss this change and its effect on IMG trainees and their selection process.

Systematic Review of COVID-19 Related Myocarditis: Insights on Management and Outcome.

INTRODUCTION: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), also referred to as COVID-19, was declared a pandemic by the World Health Organization in March 2020. The manifestations of COVID-19 are widely variable and range from asymptomatic infection to multi-organ failure and death. Like other viral illnesses, acute myocarditis has been reported to be associated with COVID-19 infection. However, guidelines for the diagnosis of COVID-19 myocarditis have not been established. METHODS: Using a combination of search terms in the PubMed/Medline, Ovid Medline and the Cochrane Library databases and manual searches on Google Scholar and the bibliographies of articles identified, we reviewed all cases reported in the English language citing myocarditis associated with COVID-19 infection. RESULTS: Fourteen records comprising a total of fourteen cases that report myocarditis/myopericarditis secondary to COVID-19 infection were identified. There was a male predominance (58%), with the median age of the cases described being 50.4 years. The majority of patients did not have a previously identified comorbid condition (50%), but of those with a past medical history, hypertension was most prevalent (33%). Electrocardiogram findings were variable, and troponin was elevated in 91% of cases. Echocardiography was performed in 83% of cases reduced function was identified in 60%. Endotracheal intubation was performed in the majority of cases. Glucocorticoids were most commonly used in treatment of myocarditis (58%). Majority of patients survived to discharge (81%) and 85% of those that received steroids survived to discharge. CONCLUSION: Guidelines for diagnosis and management of COVID-19 myocarditis have not been established and our knowledge on management is rapidly changing. The use of glucocorticoids and other agents including IL-6 inhibitors, IVIG and colchicine in COVID-19 myocarditis is debatable. In our review, there appears to be favorable outcomes related to myocarditis treated with steroid therapy. However, until larger scale studies are conducted, treatment approaches have to be made on an individualized case-by-case basis.

Outcomes of MitraClip Placement in Patients With Liver Cirrhosis.

INTRODUCTION: Liver cirrhosis is associated with increased morbidity and mortality. Many preoperative risk assessment tools do not take into account the presence or degree of liver cirrhosis prior to surgery. Over recent years, percutaneous mitral valve repair using MitraClip has emerged as an option for patients at high risk of surgical intervention. However, the safety, efficacy and outcomes of this procedure in patients with liver cirrhosis have not yet been evaluated. METHODS: This is a retrospective cohort study using the 2013-2017 National Inpatient Sample database of adults who were hospitalized for MitraClip repair of mitral valve. All patients were divided into patients with cirrhosis and those without cirrhosis. The primary outcome was all-cause mortality in patient with cirrhosis who underwent MitraClip. The secondary outcomes were to assess length of stay (LOS) and total hospital cost per year in cirrhotic patients compared to non-cirrhotic patients. RESULTS: In-hospital mortality was higher in cirrhosis group compared to non-cirrhosis however not statistically significant (8.1% vs 3.2%, OR: 2.59 [95% CI: 0.47-14.28, p-value 0.27). Additionally, neither of the secondary outcomes, LOS and total cost, were found to be statistically significant. However, the incidence of cardiogenic shock was significantly higher in the cirrhosis group 13.3% versus 3.9% (p-value 0.032). CONCLUSION: Patients with liver cirrhosis who underwent MitraClip repair of MV were at higher risk of developing cardiogenic shock, without any significant increase in in-hospital mortality, LOS or total cost. However, this study showed a trend toward higher rates of mortality, requirement of blood transfusion, mechanical ventilation, length of stay, and cost of care in cirrhosis patients.

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.

Acute Myocardial Infarction in Systemic Mastocytosis: Case Report With Literature Review on the Role of Inflammatory Process in Acute Coronary Syndrome.

BACKGROUND: Systemic Mastocytosis (SM) is a disorder of excessive mast cell infiltration in multiple organ tissues. Atherosclerosis is a major risk factor for developing acute coronary syndrome. In addition to lipid accumulation in the arterial wall, inflammation plays an important role in the pathogenesis of plaque rupture and activating the thrombosis cascade. The Mast cells contribution to plaque destabilization has been well established in multiple animal and human studies. In a recent study, SM has been proven to be associated with a higher incidence of acute coronary syndrome even with lower plasma lipids levels. The study showed that 20% of patients with SM had cardiovascular events compared to only 6% in the control group with adjustment to all cardiac risk factors. CASE: We presented a patient with no risk factors for heart disease other than old age and history of SM who developed acute myocardial infarction. CONCLUSION: SM can be life-threatening and can result in ACS, anaphylactic reaction, syncope, or cardiac arrest. Clinicians should have a high index of suspicion of acute coronary syndrome (ACS) occurrence in the setting of inflammatory conditions, such as SM and KS, and vice versa, where SM should be considered or ruled out in patients who suffer from anaphylaxis and cardiac arrest or myocardial infarction.

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.

Serious Adverse Events Cluster in Participants Experiencing the Primary Composite Cardiovascular Endpoint: A Post Hoc Analysis of the SPRINT Trial.

BACKGROUND: Intensively treated participants in the SPRINT study experienced fewer primary cardiovascular composite study endpoints (CVD events) and lower mortality, although 38% of participants experienced a serious adverse event (SAE). The relationship of SAEs with CVD events is unknown. METHODS: CVD events were defined as either myocardial infarction, acute coronary syndrome, decompensated heart failure, stroke, or death from cardiovascular causes. Cox models were utilized to understand the occurrence of SAEs with CVD events according to baseline atherosclerotic cardiovascular disease (ASCVD) risk. RESULTS: SAEs occurred in 96% of those experiencing a CVD event but only in 34% (P < 0.001) of those not experiencing a CVD event. Occurrence of SAEs monotonically increased across the range of baseline ASCVD risk being approximately twice as great in the highest compared with the lowest risk category. SAE occurrence was strongly associated with ASCVD risk but was similar within risk groups across treatment arms. In adjusted Cox models, experiencing a CVD event was the strongest predictor of SAEs in all risk groups. By the end of year 1, the hazard ratios for the low, middle, and high ASCVD risk tertiles, and baseline clinical CVD group were 2.56 (95% CI = 1.39-4.71); 2.52 (1.63-3.89); 3.61 (2.79-4.68); 1.86 (1.37-2.54), respectively-a trend observed in subsequent years until study end. Intensive treatment independently predicted SAEs only in the second ASVCD risk tertile. CONCLUSIONS: The occurrence of SAEs is multifactorial and mostly related to prerandomization patient characteristics, most prominently ASCVD risk, which, in turn, relates to in-study CVD events.

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.

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.

Impact of oral anticoagulants on 30-day readmission: a study from a single academic centre.

Researchers are extensively searching for modifiable risk factors including high-risk medications such as anticoagulation to avoid rehospitalisation. The influence of oral anticoagulant therapy on hospital readmission is not known. We investigated the impact of warfarin and direct oral anticoagulants (DOACs) on all cause 30-day hospital readmission retrospectively in an academic centre. We study the eligible cohort of 1781 discharges over 2-year period. Data on age, gender, diagnoses, 30-day hospital readmission, discharge medications and variables in the HOSPITAL score (Haemoglobin level at discharge, Oncology at discharge, Sodium level at discharge, Procedure during hospitalisation, Index admission, number of hospital Admissions, Length of stay) and LACE index (Length of stay, Acute/emergent admission, Charlson comorbidity index score, Emergency department visits in previous 6 months), which have higher predictability for readmission were extracted and matched for analysis. Warfarin was the most common anticoagulant prescribed at discharge (273 patients) with a readmission rate of 20% (p<0.01). DOACs were used by 94 patients at discharge with a readmission rate of 4% (p=0.219). Multivariate logistic regression showed an increased risk of readmission with warfarin therapy (OR 1.36, p=0.045). Logistic regression did not show DOACs to be a risk factor for hospital readmission. Our data suggests that warfarin therapy is a risk factor for all-cause 30-day hospital readmission. DOAC therapy is not found to be associated with a higher risk of hospital readmission. Warfarin anticoagulation may be an important target for interventions to reduce hospital readmissions.
