This study aimed to evaluate the accuracy of HOSPITAL Score (Haemoglobin level at discharge, Oncology Sodium Procedure during hospitalization, Index admission, number hospital admissions, Length stay) LACE index (Length stay, Acute/emergent Charlson comorbidy score, Emerency department visits in previous 6 months) and LACE+ predicting 30-day readmission patients with diastolic dysfunction. Heart failure remains one most common readmissions adults, leading significant morbidity mortality....

Abstract Background Transcatheter mitral valve repair (TMVR) is a treatment option for patients with 3+ or greater regurgitation who cannot undergo surgery. Outcomes in chronic kidney disease (CKD) and end stage renal (ESRD) are unclear. We sought to evaluate the TMVR in‐hospital outcomes, readmission rates its impact on function. Methods Data from 2016 National Readmission Database was used obtain all underwent TMVR. Patients were classified by their CKD status: no CKD, ESRD. The primary...

Objectives To demonstrate a magnitude of the cardiovascular benefits, concomitantly analyzing safety outcomes sodium-glucose cotransporter 2 inhibitor (SGLT2-I) comprehensively, as class effect in larger sample size combined from recent randomized control trials. Methods We searched electronic databases using specific terms and evaluated 6 efficacy 10 outcomes. Odds ratios (ORs) 95% confidence interval (CI) were used to compare two interventions. Results Five studies ( n = 41 267) included,...

Stress-induced cardiomyopathy, also known as Takotsubo cardiomyopathy (TTS), is characterized by transient regional systolic dysfunction. Furthermore, electrocardiogram (ECG) changes can vary TTS evolves. We report a case of 67-year-old woman who presented to the ER after cardiac arrest. She was found have stress-induced with prolonged QTc interval. The patient developed torsades de pointes for which she required cardioversion, followed improvement interval corresponding resolution...

Introduction: Transcatheter Aortic Valve Replacement (TAVR) has been established as a viable alternative to surgical aortic valve replacement (SAVR) when treating symptomatic stenosis in intermediate and high risk patients. Historically, general endotracheal anesthesia (GETA) the primary form of patient sedation during TAVR. Recently, conscious (CS) utilized safe option. As there are limited data available comparing these two modalities, it would be helpful investigate this question further....

e12540 Background: Cardiovascular disease is one of the leading causes deaths in breast cancer patients. Pre-existing cardiac conditions and cardiovascular risks associated with chemotherapy affect overall mortality these Cardio protective medications like beta-blocker, ACEIs, ARBs, statin, potassium-sparing diuretics have shown to increase survival odds. In our study, we investigated patients who were on cardio medications. Methods: Our retrospective cohort study included from Simmons...

e12548 Background: Chemotherapy-induced cardiotoxicity has been associated with certain breast cancer therapy regimens, such as anthracyclines. With the development of newer therapies, just anti HER2 agents,another association recognized in these drug groups. We report cardiac safety anti-HER2 agents and Methods: A retrospective chart review was conducted patients diagnosed between January 1st 2014 December 31st 2017, treated chemotherapy were identified from a large center database. Heart...

e12616 Background: The most common female malignancy diagnosed in the US is breast cancer. Early cancer therapy often treated with radiation therapy; one of unfortunate side effects radiotherapy past has been cardiotoxicity, especially coronary artery disease. Recent usage dose reduction techniques have helped reduce these effects. Here, we present our analysis patients that received and likelihood cardiotoxicity. Methods: An IRB-approved retrospective study was performed utilizing ICD codes...

e12549 Background: Breast cancer remains the number one threat to women’s health while cardiovascular disease (CVD) continues be leading cause of mortality in women worldwide. Adjuvant therapy with endocrine therapies (selective estrogen receptor modulators (SERM), blockers (ERB), and aromatase inhibitors (AI) although known reduce recurrence breast hormone positive patients, raise a concern for increased risk disease. Our study aims examine survival outcomes on patients receiving who have...

e13620 Background: Breast cancer is the most common female malignancy diagnosed in US. According to CDC and WWAMI Rural Health Research Center, rural areas have a lower incidence of than urban areas, yet higher breast related death rates (1,2). Adverse cardiac outcomes may contribute decreased survival populations. In this abstract, we discuss how environment impacts patients with cancer.

The subtype was HR+/HER2 based on 2012-2016 cases, a much higher rate than triple negative Best survival rates are found among women with HR+/HER2- followed by HR+/HER2+ and HR-/HER+ subtypes. Triple comparatively had poorer survival.Our objective to determine molecular in central Illinois population. Methods: A cohort 478 patients diagnosed between...
