Clinical Outcomes For Impella Procedure In Octogenarians, Nonagenarians, And Centenarians: A Retrospective Cohort Study, Tony Elias, Sonika Vatsa, Kyrillos Girgis, Michael Valderrama, Rafail Beshai

Rowan-Virtua Research Day

The Impella, a vital ventricular assist device, has seen extensive use in managing severe heart failure and cardiogenic shock. However, the impact of this procedure on older individuals remains poorly understood. To address this gap, we scrutinized the National Inpatient Sample Database from 2019 to 2020 to elucidate in-hospital outcomes among older patients who underwent the Impella procedure. Among the 8233 patients who underwent Impella insertion, 1389 (16.8%) were in the older population, aged 80 years or older. This subgroup exhibited a higher prevalence of comorbidities such as hypertension, diabetes mellitus, and chronic kidney disease compared to younger patients. Alarmingly, …

Clinical Outcomes For Cardiac Ablation In Octogenarians, Nonagenarians, And Centenarians: A Retrospective Cohort Study, Tony Elias, Mena Elmalh, Kyrillos Girgis, Michael Valderrama, Rafail Beshai

Rowan-Virtua Research Day

Background

Cardiac ablation is a therapeutic intervention aimed at correcting abnormal heart rhythms by disrupting electrical pathways in the heart, using techniques such as radiofrequency or cryoablation. Despite its effectiveness, there is a scarcity of data regarding the outcomes of cardiac ablation specifically among elderly patients. Previous studies have highlighted the complexities and challenges associated with managing cardiac arrhythmias in the elderly population, emphasizing the need for further investigation into treatment outcomes in this demographic.1,2 Therefore, this study aimed to investigate in-hospital outcomes among elderly patients who underwent cardiac ablation using data from the National Inpatient Sample (NIS) Database.

Division of Cardiology Faculty Papers

BACKGROUND: The prevalence of multimorbidity in patients with acute myocardial infarction (AMI) is increasing. It is unclear whether comorbidities cluster into distinct phenogroups and whether are associated with clinical trajectories.

METHODS: Survey-weighted analysis of the United States Nationwide Inpatient Sample (NIS) for patients admitted with a primary diagnosis of AMI in 2018. In-hospital outcomes included mortality, stroke, bleeding, and coronary revascularisation. Latent class analysis of 21 chronic conditions was used to identify comorbidity classes. Multivariable logistic and linear regressions were fitted for associations between comorbidity classes and outcomes.

RESULTS: Among 416,655 AMI admissions included in the analysis, mean (±SD) age …

How Do We Define High And Low Dose Intensity Of Heart Failure Medications: A Scoping Review, Min Ji Kwak, Qian Wang, Chukwuma Onyebeke, Travis Holder, Parag Goyal, Rajender Aparasu, Abhjeet Dhoble, Holly M Holmes

Journal Articles

BACKGROUND: Older adults with heart failure often experience adverse drug events with high doses of heart failure medications. Recognizing whether a patient is on a high or low dose intensity heart failure medication can be helpful for daily practice, since it could potentially guide the physician on which symptoms to look for, whether from overdosing or underdosing. However, the current guideline does not provide sufficient information about the dose intensity below the target dose. Furthermore, the definition of high or low-intensity heart failure medication is unclear, and there is no consensus.

METHODS: To close the knowledge gap, we conducted a …

Division of Cardiology Faculty Papers

BACKGROUND: Coronavirus disease 2019 (COVID-19) is associated with excess risk of cardiovascular and thrombotic events in the early post-infection period and during convalescence. Despite the progress in our understanding of cardiovascular complications, uncertainty persists with respect to more recent event rates, temporal trends, association between vaccination status and outcomes, and findings within vulnerable subgroups such as older adults (aged 65 years or older), or those undergoing hemodialysis. Sex-informed findings, including results among pregnant and breastfeeding women, as well as adjusted comparisons between male and female adults are similarly understudied.

METHODS: Adult patients, aged ≥18 years, with polymerase chain reaction-confirmed COVID-19 …

Prescribing Patterns Of Fall Risk-Increasing Drugs In Older Adults Hospitalized For Heart Failure, Esther Liu, Musarrat Nahid, Mahad Musse, Ligong Chen, Sarah N Hilmer, Andrew Zullo, Min Ji Kwak, Mark Lachs, Emily B Levitan, Monika M Safford, Parag Goyal

Journal Articles

BACKGROUND: Older adults hospitalized for heart failure (HF) are at risk for falls after discharge. One modifiable contributor to falls is fall risk-increasing drugs (FRIDs). However, the prevalence of FRIDs among older adults hospitalized for HF is unknown. We describe patterns of FRIDs use and examine predictors of a high FRID burden.

METHODS: We used the national biracial REasons for Geographic and Racial Differences in Stroke (REGARDS) study, a prospective cohort recruited from 2003-2007. We included REGARDS participants aged ≥ 65 years discharged alive after a HF hospitalization from 2003-2017. We determined FRIDs -cardiovascular (CV) and non-cardiovascular (non-CV) medications - …

Real-World Safety Of Neurohormonal Antagonist Initiation Among Older Adults Following A Heart Failure Hospitalization, Parag Goyal, Andrew R Zullo, Barbara Gladders, Chukwuma Onyebeke, Min Ji Kwak, Larry A Allen, Emily B Levitan, Monika M Safford, Lauren Gilstrap

Journal Articles

AIMS: To optimize guideline-directed medical therapy for heart failure, patients may require the initiation of multiple neurohormonal antagonists (NHAs) during and following hospitalization. The safety of this approach for older adults is not well established.

METHODS AND RESULTS: We conducted an observational cohort study of 207 223 Medicare beneficiaries discharged home following a hospitalization for heart failure with reduced ejection fraction (HFrEF) (2008-2015). We performed Cox proportional hazards regression to examine the association between the count of NHAs initiated within 90 days of hospital discharge (as a time-varying exposure) and all-cause mortality, all-cause rehospitalization, and fall-related adverse events over the …

Short-Term Removal Of Exercise Impairs Glycemic Control In Older Adults: A Randomized Trial, Leryn J. Reynolds, Troy M. Williams, Joel E. Harden, Hannah M. Twiddy, Monica L. Kearney

Human Movement Sciences & Special Education Faculty Publications

Postprandial glycemia (PPG) predicts cardiovascular disease, and short-term physical inactivity increases PPG in young, active adults. Whether this occurs in older, active adults who may be more prone to bouts of inactivity is unknown. This study determined if postprandial interstitial glucose (PPIG) was impaired in active older adults following the removal of exercise for 3 days (NOEX) compared to active young adults. In this randomized, crossover study, 11 older (69.1 ± 1.9 years) and 9 young (32.8 ± 1.8 years) habitually active (≥90 min/week of exercise) adults completed 3-days of NOEX and 3-days of normal habitual exercise (EX), separated by …

A Right Atrial Mass With Fever And Cutaneous Nodules, Feng Gao, Stephanie Koh, Sara Taveras-Alam, Umair Khalid

Journal Articles

Primary cardiac tumors, although exceedingly rare, should be considered in the differential diagnosis during workup of any cardiac mass. Extranodal cardiac lymphomas have a natural aggressive course due to delayed diagnosis. We present a 71-year-old male with a dual-chamber pacemaker who presented with fevers and new cutaneous nodules. He was found to have a right atrial primary anaplastic large-cell lymphoma and had a complete metabolic response after chemotherapy. Our case highlights the importance of a multimodality approach in the diagnosis of cardiac tumors and during follow-up after treatment.

Utility Of Blood Cellular Indices In The Risk Stratification Of Patients Presenting With Acute Pulmonary Embolism., Brett Slajus, Yevgeniy Brailovsky, Iman Darwish, Jawed Fareed, Amir Darki

Division of Cardiology Faculty Papers

Pulmonary embolism (PE) clinical manifestations vary widely, and that scope is not fully captured by current all-cause mortality risk models. PE is associated with inflammatory, coagulation, and hemostatic imbalances so blood cellular indices may be prognostically useful. Complete blood count (CBC) data may improve current risk models like the simplified pulmonary embolism severity index (sPESI) for all-cause mortality, offering greater accuracy and analytic ability. Acute PE patients (n = 228) with confirmatory diagnostic imaging were followed for all-cause mortality. Blood cellular indices were assessed for association to all-cause mortality and were supplemented into sPESI using multivariate logistic regression. Multiple blood …

Bilateral Lower Extremity Ischemia Following Cardiac Catheterization, Moses Avedikian, Alan Lucerna, Trent Malcolm

Rowan-Virtua Research Day

Acute limb ischemia is a rare yet limb-threatening presentation where rapid diagnosis and intervention is warranted. Bilateral lower extremity ischemia can be a rare complication following procedures, such as a cardiac catheterization with access obtained in the groin. We describe a case of a 79-year-old female who presented with bilateral lower extremity ischemia following a cardiac catheterization 2 weeks prior. The patient underwent CT angiography, which demonstrated occlusion with no contrast present in the bilateral femoral arteries.

The Relationship Of Cardiovascular Disease To 30-Day Hospital Readmission Among Older Adults With Type 2 Diabetes Mellitus, Meet Shah, Shmilah Choudhary, Sanath Shetty, Terrie Ginsberg D.O., Matthew H. Mclaughlin

Rowan-Virtua Research Day

Reducing thirty-day hospital readmissions is a top healthcare priority. However, there is little research describing the risk factors of readmission among patients with diabetes, especially for older adults. Understanding what the risk factors are for 30-day hospital readmission for older adults with type 2 diabetes (T2DM) would help identify patients at risk of rehospitalization. The aim of this study was to identify factors associated with 30-day unplanned hospital readmissions among older adults with T2DM.Factors to be investigated are: patient demographics and whether the patient was hospitalized for cardiovascular disease. Participants were older adults>65 years old with T2DM, admitted to …

Ucp1 Expression-Associated Gene Signatures Of Human Epicardial Adipose Tissue., Kanta Chechi, Jinchu Vijay, Pierre Voisine, Patrick Mathieu, Yohan Bossé, Andre Tchernof, Elin Grundberg, Denis Richard

Manuscripts, Articles, Book Chapters and Other Papers

Multiple reports of uncoupling protein 1 (UCP1) expression have established its presence in human epicardial adipose tissue (eAT). Its functional relevance to eAT, however, remains largely unknown. In a recent study, we reported that adrenergic stimulation of eAT was associated with downregulation of secreted proteins involved in oxidative stress-related and immune-related pathways. Here, we explored the UCP1-associated features of human eAT using next-generation deep sequencing. Paired biopsies of eAT, mediastinal adipose tissue (mAT), and subcutaneous adipose tissue (sAT) obtained from cardiac surgery patients, with specific criteria of high and low expression of UCP1 in eAT, were subjected to RNA sequencing. …

Gill Heart & Vascular Institute Faculty Publications

BACKGROUND

Despite the high rate of sudden death after myocardial infarction among patients with a low ejection fraction, implantable cardioverter–defibrillators are contraindicated until 40 to 90 days after myocardial infarction. Whether a wearable cardioverter–defibrillator would reduce the incidence of sudden death during this high-risk period is unclear.

METHODS

We randomly assigned (in a 2:1 ratio) patients with acute myocardial infarction and an ejection fraction of 35% or less to receive a wearable cardioverter–defibrillator plus guideline-directed therapy (the device group) or to receive only guideline-directed therapy (the control group). The primary outcome was the composite of sudden death or death from …

Parkview Pharmacy Department

Anticoagulation with unfractionated heparin during extracorporeal membrane oxygenation (ECMO) is common, but alternative agents are being evaluated for safety and efficacy. The objective of this analysis was to assess if a comprehensive bivalirudin dosing and monitoring protocol effectively guides dose adjustments and monitoring of bivalirudin in patients during ECMO. Our analysis included 11 patients who received bivalirudin during ECMO therapy and had dosing managed using our hospital derived protocol. Patients treated over a 1-year period were included in this retrospective analysis. Clinical characteristics and changes in activated partial thromboplastin time (aPTT) were evaluated from medical records to determine the efficacy …

Myocardial Dysfunction After Out-Of-Hospital Cardiac Arrest: Predictors And Prognostic Implications., Yuan Yao, Nicholas James Johnson, Sarah Muirhead Perman, Vimal Ramjee, Anne Victoria Grossestreuer, David Foster Gaieski

Department of Emergency Medicine Faculty Papers

We aim to determine the incidence of early myocardial dysfunction after out-of-hospital cardiac arrest, risk factors associated with its development, and association with outcome. A retrospective chart review was performed among consecutive out-of-hospital cardiac arrest (OHCA) patients who underwent echocardiography within 24 h of return of spontaneous circulation at three urban teaching hospitals. Our primary outcome is early myocardial dysfunction, defined as a left ventricular ejection fraction < 40% on initial echocardiogram. We also determine risk factors associated with myocardial dysfunction using multivariate analysis, and examine its association with survival and neurologic outcome. A total of 190 patients achieved ROSC and underwent echocardiography within 24 h. Of these, 83 (44%) patients had myocardial dysfunction. A total of 37 (45%) patients with myocardial dysfunction survived to discharge, 39% with intact neurologic status. History of congestive heart failure (OR 6.21; 95% CI 2.54-15.19), male gender (OR 2.27; 95% CI 1.08-4.78), witnessed arrest (OR 4.20; 95% CI 1.78-9.93), more than three doses of epinephrine (OR 6.10; 95% CI 1.12-33.14), more than four defibrillations (OR 4.7; 95% CI 1.35-16.43), longer duration of resuscitation (OR 1.06; 95% CI 1.01-1.10), and therapeutic hypothermia (OR 3.93; 95% CI 1.32-11.75) were associated with myocardial dysfunction. Cardiopulmonary resuscitation immediately initiated by healthcare personnel was associated with lower odds of myocardial dysfunction (OR 0.40; 95% CI 0.17-0.97). There was no association between early myocardial dysfunction and mortality or neurological outcome. Nearly half of OHCA patients have myocardial dysfunction. A number of clinical factors are associated with myocardial dysfunction, and may aid providers in anticipating which patients need early diagnostic evaluation and specific treatments. Early myocardial dysfunction is not associated with neurologically intact survival.

Differential Impact Of Serial Measurement Of Nonplatelet Thromboxane Generation On Long-Term Outcome After Cardiac Surgery., Nikolaos Kakouros, Tyler J Gluckman, John V Conte, Thomas S Kickler, Katherine Laws, Bruce A Barton, Jeffrey J Rade

Articles, Abstracts, and Reports

BACKGROUND: Systemic thromboxane generation, not suppressible by standard aspirin therapy and likely arising from nonplatelet sources, increases the risk of atherothrombosis and death in patients with cardiovascular disease. In the RIGOR (Reduction in Graft Occlusion Rates) study, greater nonplatelet thromboxane generation occurred early compared with late after coronary artery bypass graft surgery, although only the latter correlated with graft failure. We hypothesize that a similar differential association exists between nonplatelet thromboxane generation and long-term clinical outcome.

METHODS AND RESULTS: Five-year outcome data were analyzed for 290 RIGOR subjects taking aspirin with suppressed platelet thromboxane generation. Multivariable modeling was performed to …

Articles, Abstracts, and Reports

Cardiovascular magnetic resonance (CMR) perfusion has been established as a useful imaging modality for the detection of coronary artery disease (CAD). However, there are several limitations when applying standard, ECG-gated stress/rest perfusion CMR to patients with atrial fibrillation (AF). In this study we investigate an approach with no ECG gating and a rapid rest/stress perfusion protocol to determine its accuracy for detection of CAD in patients with AF. 26 patients with AF underwent a rapid rest/regadenoson stress CMR perfusion imaging protocol, and all patients had X-ray coronary angiography. An ungated radial myocardial perfusion sequence was used. Imaging protocol included: rest …

Department of Medicine Faculty Papers

A single dose of the apolipoprotein (apo)A-I mimetic peptide D-4F rendered high-density lipoprotein (HDL) less inflammatory, motivating the first multiple-dose study. We aimed to assess safety/tolerability, pharmacokinetics, and pharmacodynamics of daily, orally administered D-4F. High-risk coronary heart disease (CHD) subjects added double-blinded placebo or D-4F to statin for 13 days, randomly assigned 1:3 to ascending cohorts of 100, 300, then 500 mg (n = 62; 46 men/16 women). D-4F was safe and well-tolerated. Mean ± SD plasma D-4F area under the curve (AUC, 0-8h) was 6.9 ± 5.7 ng/mL*h (100 mg), 22.7 ± 19.6 ng/mL*h (300 mg), and 104.0 ± …

Vitamin D, Heidi D Moretti, Vincent J Colucci, Bradley D Berry

Articles, Abstracts, and Reports

BACKGROUND: Vitamin D status may influence heart failure (HF) patient outcomes by affecting b-type natriuretic peptide (BNP), parathyroid hormone (PTH), and enhancing cardiac contractility. Vitamin D deficiency is associated with morbidity and mortality in HF patients. The objective of this study was to determine if vitamin D3 at a comparatively high dose would replete 25-hydroxyvitamin D (25(OH)D) stores, improve BNP, PTH, cardiopulmonary function, reduce inflammatory markers, and improve quality of life (QOL) in HF patients.

METHODS: This was a 6 month, parallel group, double-blind, placebo-controlled, single clinic center, randomized trial of supplemental vitamin D3 using a dose of 10,000 IU …
