In-hospital outcomes in unhoused patients with cardiogenic shock in the United States: Insights from The National Inpatient Sample 2011-2019.

BACKGROUND: Unhoused patients face significant barriers to receiving health care in both the inpatient and outpatient settings. For unhoused patients with heart failure who are in extremis, there is a lack of data regarding in-hospital outcomes and resource utilization in the setting of cardiogenic shock (CS). HYPOTHESIS: Unhoused patients hospitalized with CS have increased mortality and decreased use of invasive therapies as compared to housed patients. METHODS: The National Inpatient Sample (NIS) database was queried from 2011 to 2019 for relevant ICD-9 and ICD-10 codes to identify unhoused patients with an admission diagnosis of CS. Baseline characteristics and in-hospital outcomes between patients were compared. Binary logistic regression was used to adjust outcomes for prespecified and significantly different baseline characteristics (p < .05). RESULTS: We identified a weighted sample of 1 202 583 adult CS hospitalizations, of whom 4510 were unhoused (0.38%). There was no significant difference in the comorbidity adjusted odds of mortality between groups. Unhoused patients had lower odds of receiving mechanical circulatory support, left heart catheterization, percutaneous coronary intervention, or pulmonary artery catheterization. Unhoused patients had higher adjusted odds of infectious complications, undergoing intubation, or requiring restraints. CONCLUSIONS: These data suggest that, despite having fewer traditional comorbidities, unhoused patients have similar mortality and less access to more aggressive care than housed patients. Unhoused patients may experience under-diuresis, or more conservative care strategies, as evidenced by the higher intubation rate in this population. Further studies are needed to elucidate long-term outcomes and investigate systemic methods to ameliorate barriers to care in unhoused populations.

Evaluation of Inpatient Sodium-Glucose Co-Transporter-2 Inhibitor Use in Patients Hospitalized for Acute Heart Failure.

Hospitalization for acute heart failure (HF) represents an important opportunity for initiation and up-titration of guideline-directed medical therapy. This study aimed to determine whether sodium-glucose co-transporter-2 inhibitor (SGLT2I) use is safe in patients hospitalized for acute HF and whether its use is associated with improved clinical outcomes. We conducted a single-center, retrospective cohort study of adults hospitalized for acute HF with any ejection fraction and separated them into 2 matched groups based on inpatient SGLT2I use. The matching yielded 110 patients in the SGLT2I group and 110 patients in the control group. A total of 101 patients (91.8%) in the SGLT2I group were treated with dapagliflozin, whereas 9 (8.2%) were treated with empagliflozin. The mean age was 71 years, 37.7% were women, 70.9% were White, 22.7% were Black, and 64.1% were Hispanic or Latino. The length of stay was 10 days in the SGLT2I group and 11 days in the control group (p = 0.43). A total of 2 patients (1.8%) in the SGLT2I group and 13 patients (11.8%) in the control group died within 30 days of discharge (hazard ratio 0.15, 95% confidence interval [CI] 0.03 to 0.66, p = 0.012). A total of 17 patients (15.5%) in the SGLT2I group and 11 patients (10.0%) in the control group had an all-cause readmission within 30 days (hazard ratio 1.58, 95% CI 0.74 to 3.37, p = 0.239). In addition, 11 patients (10.0%) in the SGLT2I group and 3 patients (2.7%) in the control group had an HF readmission within 30 days (hazard ratio 3.75, 95% CI 1.05 to 13.44, p = 0.042). Acute kidney injury (54.5% vs 18.2%, p <0.001) and hypotension (12.7% vs 2.7%, p = 0.005) occurred significantly more frequently in the control group. In conclusion, SGLT2I use in patients hospitalized for acute HF was associated with decreased 30-day all-cause mortality and lower rates of acute kidney injury and hypotension; however, the rate of 30-day HF readmission increased.

Characteristics, Risk Factors, and Outcome of New-onset Systolic Heart Failure After Liver Transplantation: A Single-center Cohort.

New-onset systolic heart failure (HF) after liver transplantation (LT) is a significant cause of morbidity and mortality; however, its characteristics are still insufficiently delineated. HF may involve the left ventricle (LV), right ventricle (RV), or both ventricles. We explored the incidence, characteristics, etiologies, risks, involved cardiac chambers, and outcomes of HF after LT. Methods: This study included 528 adult patients with preoperative LV ejection fraction ≥ 55% who underwent LT between 2016 and 2020. The primary outcome was new-onset systolic HF, defined by the presence of clinical signs, symptoms, and echocardiographic evidence of reduced LVejection fraction <50% and RV dysfunction within the first year after LT. Results: Thirty-one patients (6%) developed systolic HF within a median of 9 d (1-364). Of those, 23% of patients had ischemic HF, whereas 77% had nonischemic HF. Nonischemic HF was caused by stress (11), sepsis (8), or other factors (5). Nonischemic HF was secondary to isolated LV failure in 58% of patients or RV ± LV failure in 42% of patients. Recursive partitioning identified subgroups with varying risks and uncovered interaction between variables. HF risk increased from 4.2% to 13% when epinephrine and/or norepinephrine drips were used intraoperatively (P < 0.01). When no epinephrine and/or norepinephrine were used, HF risk increased from 3.1% to 38.5% if baseline hemoglobin was <7.2 g/dL (P < 0.01). When baseline hemoglobin was ≥7.2 g/dL, HF risk increased from 0% to 5.2% when ≥3500 mL crystalloid was used intraoperatively (P < 0.01). Posttransplant first-year survival and reversibility of HF depended on the etiology (stress, sepsis, ischemia, etc) and cardiac chamber involvement (isolated LV or RV ± LV). RV dysfunction was associated with inferior recovery of cardiac function and poorer survival than nonischemic isolated LV dysfunction (50% versus 70%, respectively). Conclusions: Posttransplant new-onset HF is mostly nonischemic in nature and is associated with increased morbidity and mortality.

The association of pre-transplant atrial fibrillation with in-hospital outcomes in patients undergoing orthotopic liver transplantation: A propensity score matching analysis.

INTRODUCTION: In this study, we sought to evaluate the prevalence and association of pre-transplant atrial fibrillation (AF) on 30-day postoperative outcomes in patients undergoing orthotopic liver transplant (OLT). METHOD: The National Inpatient Sample Database was queried from 2011 to 2017 for relevant ICD-9 and ICD-10 procedural and diagnostic codes. Baseline characteristics and in-hospital outcomes were compared in patients who underwent OLT with AF and those without. RESULTS: Among 45,357 patients who underwent OLT, women made up 35.8% of the overall population. The prevalence of AF before transplant was 2932 (6.5%) with a trend toward increasing prevalence, with an average annual change rate of 4.19%. Applying propensity score matching to control for potential confounding factors, there was no association between pre-transplant AF and in-hospital mortality in patients undergoing OLT, however there was a higher incidence of perioperative complications including: acute kidney injury, ventricular tachycardia, major bleeding, blood product transfusion, and septic shock. CONCLUSION: In patients undergoing OLT, pre-transplant AF is increasing in prevalence and appears to be associated with similar in-hospital mortality but worse perioperative outcomes. Greater emphasis should be placed on AF in the preoperative cardiovascular risk stratification of patients undergoing OLT.

A comprehensive review of coronary artery disease in patients with end-stage liver disease.

The prevalence of coronary artery disease has increased in patients with end stage liver disease. In the near future, non-alcoholic steatohepatitis is expected to be the leading cause of end stage liver disease and shares common risk factors with coronary artery disease such as hypertension, hyperlipidemia, obesity and diabetes mellitus. At present, liver transplantation is the only definitive treatment for end stage liver disease, with post-operative mortality associated with the presence of coronary artery disease. Given the high prevalence of cardiovascular disease and the unique balance of pro-thrombotic and antithrombotic factors in patients with end stage liver disease, we sought to discuss the non-invasive and invasive diagnosis, medical and procedural management considerations and pre-transplant evaluation of coronary artery disease in patients with end stage liver disease.

Heart Brake: An Unusual Cardiac Manifestation of COVID-19.

A 49-year-old man presented with worsening high-grade fevers, dry cough, and shortness of breath. He tested positive for severe acute respiratory syndrome-coronavirus-2 and was noted to have bradycardia with intermittent high-degree atrioventricular block. However, cardiac biomarkers and echocardiographic findings were normal, thus making this an unusual and interesting manifestation of myocardial involvement of this novel coronavirus.

Painless type A aortic dissection.

Aortic dissection is an uncommon diagnosis that typically presents with acute onset of severe pain. It rarely presents with minimal to no symptoms, which carries a higher mortality risk given the delay in diagnosis. An adequate interpretation of risk factors, clinical findings and auxiliary tests constitutes a greater value for clinicians to detect this life-threatening condition. This report describes a case of type A aortic dissection in an asymptomatic patient presenting with an abnormal electrocardiogram (ECG).

Cancer Therapy-Related Cardiac Dysfunction: An Overview for the Clinician.

Cancer therapy-related cardiac dysfunction (CTRCD) is one of the most feared and undesirable side effects of chemotherapy, occurring in approximately 10% of the patients. It can be classified as direct (dose-dependent vs dose-independent) or indirect, either case being potentially permanent or reversible. Risk assessment, recognition, and prevention of CTRCD are crucial.

Late tissue erosion after transcatheter closure of an atrial septal defect.

We present the case of a 27-year-old male presenting with sudden-onset retrosternal chest pain, dyspnea, and cardiac tamponade due to erosion of an Amplatzer Atrial Septal Occluder (ASO) through the left atrial wall 4 years after placement. Emergent surgical management of the hemopericardium, followed by surgical removal of the device, repair of the left atrial wall perforation, and patch closure of the atrial septal defect (ASD) were performed successfully. Tissue erosion leading to hemopericardium and cardiac tamponade should be suspected in subjects with a history of transcatheter ASD closure who present with acute chest pain or dyspnea and signs of hemodynamic instability © 2015 Wiley Periodicals, Inc.

Reversible bone pain and symmetric bone scan uptake in a dialysis patient treated with cinacalcet: a case report.

INTRODUCTION: The medical management of secondary hyperparathyroidism in patients with end-stage renal disease involves a combination of dietary restrictions, phosphate binders, active vitamin D analogs, and calcimimetics. CASE PRESENTATION: We report the case of a 36-year-old Hispanic dialysis patient, originally from Cuba and now residing in the USA, who developed severe bone pain and muscle twitching after starting low dose cinacalcet, despite normal pre-dialysis ionized calcium and elevated parathyroid hormone. The clinical symptoms correlated with increased symmetrical uptake on bone scan that resolved rapidly upon discontinuation of cinacalcet. CONCLUSION: Cinacalcet may induce severe bone pain and a unique bone scan uptake pattern in hemodialysis patients.
