Transitional Care To Reduce 30-Day Heart Failure Readmissions Among The Long-Term Care Elderly Population, Shantha Franks

Seton Hall University DNP Final Projects

Throughout the nation, there is an increased focus on reducing preventable hospital readmissions. This initiative started with the Patient Protection and Affordable Care Act (PPACA) (CMS, 2014), which sets forth certain provisions for Medicare spending. Hospitals with higher than usual readmission rates, especially in terms of preventable readmissions, are receiving reductions in Medicare reimbursements (Stone & Hoffman, 2010, CMS, 2014). Congestive Heart Failure (CHF) or Heart Failure (HF) is recognized as a primary cause of 30-day hospital readmissions. Causes of HF readmission include inadequate patient education and planning for discharge, inappropriate medication reconciliation, and poor or inadequate follow-up in the …

Overweight Predicts Poorer Exercise Capacity In Congenital Heart Disease Patients, Karen Kuehl, Alicia Tucker, Munziba Khan, Paula Goldberg, E. Anne Greene, Megan Smith

Pediatrics Faculty Publications

Background

Overweight (OW) and obesity (OB) are endemic in the United States and affect adolescents and adults with congenital heart disease (ACHD). Defining the burden of excess weight on the cardiovascular system in ACHD is the goal of this study. Limitation of exercise capacity due to overweight or obesity might be reversible with weight loss and improve quality of life for ACHD adults.

Methods

Exercise tests performed using a Bruce protocol and measurement of maximum oxygen consumption were retrospectively reviewed on 418 CHD patients. OW and OB were defined as the 85–95 or > 95 percentile respectively for age and gender …

The Effect Of Neurostimulation On Ischemic Pain And Methods Of Assessing Pain, Kaylee Keck

Biomedical Engineering

Peripheral arterial disease (PAD) impacts approximately eight million people in the United States [1]. Disease progression leads to chronic ischemic pain, hindering quality of life. Pharmaceuticals are a typical treatment for pain associated with PAD; but as few as 30% of patients have a significant reduction of pain (≥50%) [2].

Neurostimulation is commonly used as a treatment for various diseases and injuries, including Parkinson’s disease and sports-related back and knee injuries [2]. The objective of the study was to explore neurostimulation and its effect on pain and paresthesia for a model of acute peripheral ischemia in young college students.

Endometrial Stromal Sarcoma Metastatic From The Uterus To The Inferior Vena Cava And Right Atrium, Daniel Scher, William Nghiem, Salim Aziz, Rodeen Rahbar, Whitney Banks, Anthony Venbrux, Shawn Sarin

The Texas Heart Institute Journal

Endometrial stromal sarcoma metastases usually occur within the pelvis and rarely involve the great vessels or the heart. We present the case of a 55-year-old woman who was referred for endovascular therapy to treat presumed thrombosis of the inferior vena cava. The suspected thrombus was recalcitrant to endovascular removal with use of an AngioVac venous drainage device. Results of an intraprocedural transvenous biopsy revealed the mass to be the intravascular extension of an endometrial stromal sarcoma. The patient underwent surgical excision of the tumor, and, shortly thereafter, a hysterectomy and salpingo-oophorectomy. This complex case highlights both the rarity of malignancy …

Multivariate Criteria Most Accurately Distinguish Cardiac From Noncardiac Causes Of Dyspnea, Mirza Nubair Ahmad, Syed Hasan Yusuf, Rafath Ullah, Mirza Mujadil Ahmad, Mary K Ellis, Haroon Yousaf, Timothy E Paterick, Khawaja Afzal Ammar

The Texas Heart Institute Journal

Cardiopulmonary exercise testing provides oxygen pulse as a continuous measure of stroke volume, which is superior to other stress-testing methods in which systolic function is measured at baseline and at peak stress. However, the optimal peak oxygen pulse criterion for distinguishing cardiac from noncardiac causes of exercise limitation is unknown.

In comparing several peak oxygen pulse criteria against the clinical standard of cardiopulmonary exercise testing, we retrospectively studied 54 consecutive patients referred for cardiopulmonary exercise testing. These exercise tests included measurement of oxygen consumption, carbon dioxide production, breathing reserve, arterial blood gases at baseline and at peak stress, exercise electrocardiogram, …

The Role Of Dna Methylation And Hydroxymethylation In Smooth Muscle Cell Phenotypic Change During Atherogenesis, Jason Williams

Dissertations and Theses (Open Access)

Atherosclerosis is a chronic arterial disease which impacts systemically the function of organs and tissues by causing inflammation and disruption of blood supply. During atherogenesis, lipid deposits, inflammation, and cells accumulate within the walls of arteries, ultimately leading to a buildup of fatty plaques and occlusion of the arterial lumen. In a multifactorial disease like atherosclerosis there are complex interplays between environmental, genetic and epigenetic risk factors. The epigenetics of atherosclerosis involving DNA methylation has been progressing from single gene to genome wide analyses. Although these epistudies have provided evidence that DNA methylation exists within certain genes during atherogenesis, the …

Tunneling A Pulmonary Artery Graft: A Simplified Way To Insert And Remove A Temporary Right Ventricular Assist Device, Pankaj Saxena, Silvana F Marasco

The Texas Heart Institute Journal

Right ventricular failure can occur early or late after left ventricular assist device implantation. Support with a right ventricular assist device is needed in patients whose right ventricular failure does not respond to conservative management. The use of a temporary right ventricular assist device can enable the recovery of right ventricular function and avoid the use of a more permanent biventricular assist device, which is associated with complications and higher costs. We present our technique of instituting temporary right ventricular assist device support in patients who have undergone left ventricular assist device implantation.

Microaxial Flow Left Ventricular Assist Device As A Bridge To Transplantation After Lvad Malfunction, Heidi J Reich, Aamir Shah, Babak Azarbal, Jon Kobashigawa, Jaime Moriguchi, Lawrence Czer, Fardad Esmailian

The Texas Heart Institute Journal

Evolving technology and improvements in the design of modern, continuous-flow left ventricular assist devices have substantially reduced the rate of device malfunction. As the number of implanted devices increases and as survival prospects for patients with a device continue to improve, device malfunction is an increasingly common clinical challenge. Here, we present our initial experience with an endovascular microaxial flow left ventricular assist device as a successful bridge to transplantation in a 54-year-old man who experienced left ventricular assist device malfunction.

Stent Thrombosis: Regional Prevalence, Risk Factors, And Outcomes, Andrew M. Ayers, Chi C. Cho, Robyn Shearer, M. Fuad Jan, Anjan Gupta

Journal of Patient-Centered Research and Reviews

Background: Stent thrombosis is an infrequent but catastrophic complication of percutaneous coronary intervention (PCI). Many studies usually involve few stent thrombosis patients, generally less than 60, given its prevalence. While dual antiplatelet therapy has decreased stent thrombosis significantly in the general population, there are still patients who present with occurrence and recurrence of stent thrombosis.

Purpose: We sought to define the prevalence of site-specific stent thrombosis in a larger cohort of patients by specific coronary territories and determine if this had an effect on cardiovascular outcomes. In addition we sought to elucidate the role of previous coronary artery bypass grafting …

Journal of Patient-Centered Research and Reviews

Background: In the United States, more than 80% of health care spending is focused on the management of chronic illnesses such as hypertension, diabetes and hyperlipidemia. Controlling these chronic diseases can lead to better health outcomes and decrease the number of preventable deaths. Patient self-management has shown to improve clinical outcomes. In a primary care setting, a multidisciplinary approach can more effectively educate patients on improving their health.

Purpose: To assess the impact of a health coach in a primary care setting as it relates to clinical outcomes.

Methods: Patients from two Aurora family medicine clinics were referred to a …

The Effect Of Percutaneous Closure Of Large Atrial Septal Defects On Right Ventricular Function In Adults, Armaan Shaikh, Alejandro Lopez-Mas, Suhail Allaqaband, Bijoy K. Khandheria, Abraham Getenet, Matt M. Umland, Maharaj Singh, Tanvir Bajwa

Journal of Patient-Centered Research and Reviews

Background: Percutaneous closure of atrial septal defects has been shown to be a safe alternative to surgery. Despite this, past studies have largely been focused on either small- to medium-sized atrial septal defects or percutaneous closure in children and young adults.

Purpose: Our study sought to examine if right ventricular function and size improved after percutaneous closure of large atrial septal defects in the adult population.

Methods: Over a 5-year span, 25 patients underwent percutaneous closure of a secundum atrial septal defect with an occluder device. A retrospective examination was conducted for each patient, including both echocardiography and chart review …

Coronary Aorta Systolic And Diastolic Pressure Indices: Two Novel Indicators For Predicting Significant Coronary Stenosis –– A Validation Against Fractional Flow Reserve, Mirza Mujadil Ahmad, Khawaja Afzal Ammar, Mirza Nubair Ahmad, Arsalan Riaz, Fatima A. Husain, Syed Shahab Kazmi, Imran Husain, Anjan Gupta

Journal of Patient-Centered Research and Reviews

Background: Since most of the coronary flow occurs in diastole, either mean Pd/Pa or iFR has been used to measure the hemodynamic significance of a coronary stenosis. We have observed that a significant pressure gradient exists in coronary stenosis even in systole, which is contrary to general understanding but similar to ankle brachial index. Furthermore, prior studies have evaluated baseline Pd/Pa (mean coronary artery/mean aorta pressure) ratio as well as iFR (instantaneous wave-free ratio obtained during entire period of diastole) to predict fractional flow reserve (FFR) ≤ 0.80. We hypothesized a simple end-systolic and -diastolic pressure measurement in the coronary …

Essentials Of Herb-Drug Interactions In The Elderly With Cardiovascular Disease, Sulaiman Sultan, Maria Viqar, Rabaiya Ali, A. Jamil Tajik, Arshad Jahangir

Journal of Patient-Centered Research and Reviews

As the number of individuals, particularly the elderly, using herbal products with prescription drugs continues to grow, the risk for adverse interactions increases but remains poorly recognized. The true incidence and nature of adverse herb reactions or herb-drug interactions remains unknown since no postmarketing surveillance mechanism exists. Adverse events are greatly underreported, and information regarding safety mainly comes from case reports and suboptimally conducted studies in a limited number of healthy young volunteers or patients with limited comorbidities. Therefore, convincing evidence for the safety of herbal products in the elderly is lacking, and the true magnitude of problems that herb-drug …

Echocardiographic Predictors Of Admission Among Patients With Heart Failure With Reduced Ejection Fraction, Chi C. Cho, Yang Shi, Robyn Shearer, Nasir Z. Sulemanjee, Dianne L. Zwicke, T. Edward Hastings, Omar M. Cheema, Vinay Thohan

Journal of Patient-Centered Research and Reviews

Background: Congestive heart failure afflicts 5.7 million people in the United States with annual incidence of 600,000 and mortality of 280,000. Heart failure accounts for greater than 1 million hospitalizations annually and the single largest inpatient Medicare expense. As the U.S. population ages and greater emphasis is placed on population health as a means to bend projected health care expenditures, large health care organizations will need to develop algorithms to identify patients at high risk with heart failure and possibly preempt hospitalizations. Doppler echocardiography is routinely performed in clinical assessment of severe heart failure.

Purpose: We sought to determine echocardiographic …

Cardiopulmonary Exercise Testing-Based Algorithm And Its Usefulness In Clinical Cardiology, Mirza Nubair Ahmad, Syed Hasan Yusuf, Rafath Ullah, Mary Ellis, Haroon Yousaf, Timothy E. Paterick, Khawaja Afzal Ammar

Journal of Patient-Centered Research and Reviews

Background: Only cardiopulmonary exercise (CPX) testing provides information on the ability of the cardiovascular system to meet the body’s metabolic demands in terms of oxygen consumption (VO₂) and carbon dioxide production (VCO₂). However, CPX testing is underutilized by cardiologists due to complex diagnostic algorithms involving up to 30 variables as well as lack of validation studies. In addition, CPX also provides oxygen (O₂) pulse as a continuous measure of stroke volume, which is its superiority to other stress modalities in which systolic function is measured at peak stress and rest. In the literature, it …

Tertiary Center Experience Of Catheter-Directed Thrombolysis For Immediately Threatened Acute Lower Limb Ischemia Of Native Vessels And Bypass Graft Thrombosis, Hani Hashim, M. Fuad Jan, Maharaj Singh, Suhail Allaqaband, Tanvir Bajwa, Anjan Gupta

Journal of Patient-Centered Research and Reviews

Background: Catheter-directed thrombolysis (CDT) is an effective therapy and a class I indication for patients with acute limb ischemia (ALI, Rutherford categories I and IIa) of less than 14 days duration, and class IIb indication for ALI (Rutherford category IIb) with symptoms more than 14 days duration. However, there is no consensus on the initial management option for ALI (Rutherford category IIb) with symptoms less than 14 days duration.

Purpose: To evaluate the safety, efficacy and outcome of CDT, with or without bailout Angiojet mechanical thrombectomy, in patients with immediately threatened acute lower extremity ischemia (Rutherford category IIb) as a …

Feasibility Of Atrial Delivery And Tracking Of Stem Cells In A Porcine Model, Nina Garlie, Timothy Hacker, Eric G. Schmuck, Jill Koch, Jayant Khitha, Amish Raval, Indrajit Choudhuri

Journal of Patient-Centered Research and Reviews

Background: Many patients undergoing open heart surgery have sinus node dysfunction and atrial fibrillation, leading to adverse outcomes. Mesenchymal stem cells (MSC) delivered at the time of surgery may have a reparative effect on atrial tissue, thereby improving sinus node function and reducing or preventing atrial fibrillation. Stem cell delivery to the atrium is entirely unstudied. This is a significant gap in medical research, as atrial disease contributes significantly to health care costs.

Purpose: The purpose of this pilot study is to establish a technique to deliver MSC to the atria through an open-chest model, to assess the safety of …

Score Big For Decreasing Mortality: Icd Risk Score Model, Linda Francaviglia, Rachel Petersen, Maria Stone, M. Eyman Mortada

Journal of Patient-Centered Research and Reviews

Background: Aurora Health Care, a system of 14 acute care hospitals in eastern Wisconsin, has been a long-time participant in the American College of Cardiology’s National Cardiovascular Data Registries, submitting data to its ICD Registry™ since 2005. Our system’s implantable cardioverter-defibrillator (ICD) procedure volume averages 930 cases annually. During 2012 we experienced an increase in in-hospital mortality/morbidity for ICD cases.

Purpose: A single-center study examining in-hospital mortality/morbidity post-ICD implant before and after changes in practice and patient selection.

Methods: ICD implants and generator changes discharged from January 1, 2009, to December 31, 2012, were included in developing a risk model …

Contemporary Usage Of Intra-Arterial Catheter-Directed Thrombolytic (Cdt) Power Pulse Spray With Rheolytic Thrombectomy In Failed Cdt Alone For Acute Limb Ischemia, Hani Hashim, M. Fuad Jan, Maharaj Singh, Suhail Allaqaband, Tanvir Bajwa, Anjan Gupta

Journal of Patient-Centered Research and Reviews

Background: Acute lower limb ischemia (ALI) caused by arterial embolism, thrombosis of native vessels, and/or grafts is a serious condition associated with substantial morbidity and mortality. Peripheral arterial thrombolysis utilizing catheter-directed thrombolytic (CDT) has become established as a useful option in the management of ALI. However, use and outcome of adjunctive power pulse spray with rheolytic thrombectomy (PPSRT) following unsuccessful CDT is underreported in the literature.

Purpose: To evaluate outcome of contemporary use of intra-arterial CDT PPSRT as an adjunct to unsuccessful standard CDT for ALI.

Methods: We reviewed 78 consecutive patients (mean age 69 ± 14.2 years, 48.8% female) …

Tuberculosis And Cardiovascular Disease: Linking The Epidemics, Moises A. Huaman, David Henson, Eduardo Ticona, Timothy R. Sterling, Beth A. Garvy

Microbiology, Immunology, and Molecular Genetics Faculty Publications

The burden of tuberculosis and cardiovascular disease (CVD) is enormous worldwide. CVD rates are rapidly increasing in low- and middle-income countries. Public health programs have been challenged with the overlapping tuberculosis and CVD epidemics. Monocyte/macrophages, lymphocytes and cytokines involved in cellular mediated immune responses against Mycobacterium tuberculosis are also main drivers of atherogenesis, suggesting a potential pathogenic role of tuberculosis in CVD via mechanisms that have been described for other pathogens that establish chronic infection and latency. Studies have shown a pro-atherogenic effect of antibody-mediated responses against mycobacterial heat shock protein-65 through cross reaction with self-antigens in human vessels. Furthermore, …

European Policies On Cardiovascular Disease Prevention And Health Promotion: A Comparative Study, Alison Council

Independent Study Project (ISP) Collection

As the number one cause of death, cardiovascular disease represents a threat to both the economic and social well being of European countries. As a result of a variety of coordinated efforts between the European Union (EU), national governments, nonprofits, private industry, and local communities, cardiovascular disease (CVD) has been decreasing in most countries in recent years. Measures such as bans on trans fats in Denmark, social mobilization and prevention policy in Finland, and nutrition labeling in the United Kingdom have had major impacts on heart disease. For instance, Finland’s prevention programs have resulted in a 63% reduction in deaths …

Efficacy Of Oral Anticoagulation In Stroke Prevention Among Sinus-Rhythm Patients Who Lack Left Atrial Mechanical Contraction After Cryoablation, José Martínez-Comendador, Javier Gualis, José Miguel Marcos-Vidal, Jonnatan Buber, Carlos Esteban Martín, Jesús Gomez-Plana, Miguel Angel Rodríguez, Ignacio Iglesias-Garriz, David Alonso, Carlos Soria, Eva Higuera Miguélez, Mario Castaño

The Texas Heart Institute Journal

The customary recommendation is that oral anticoagulation be withdrawn a few months after cryoablation for atrial fibrillation, independently of left atrial mechanical contraction in patients in sinus rhythm. Recently, a 5-fold increase in stroke has been described in sinus-rhythm patients who lack atrial mechanical contraction. One aim of this study was to evaluate the efficacy of oral anticoagulation in preventing postoperative stroke in such patients.

This prospective study divided 154 sinus-rhythm patients into 2 groups, depending on the presence (108 patients) or absence (46 patients) of left atrial mechanical contraction at 6 months after surgery, and monitored them annually for …

Down Syndrome With Complete Atrioventricular Septal Defect, Hypertrophic Cardiomyopathy, And Pulmonary Vein Stenosis, Guruprasad Mahadevaiah, Manoj Gupta, Ravi Ashwath

The Texas Heart Institute Journal

The prevalence of congenital heart disease in infants with Down syndrome is 40%, compared with 0.3% in children who have normal chromosomes. Atrioventricular and ventricular septal defects are often associated with chromosomal aberrations, such as in trisomy 21, whereas hypertrophic cardiomyopathy is chiefly thought to be secondary to specific gene mutations. We found only one reported case of congenital hypertrophic cardiomyopathy and atrioventricular septal defect in an infant with Down syndrome. Here, we report atrioventricular septal defect, hypertrophic cardiomyopathy, and pulmonary vein stenosis in a neonate with Down syndrome-an apparently unique combination. In addition, we discuss the relevant medical literature.

Evaluation Of Previously Cannulated Radial Arteries As Patent Coronary Artery Bypass Conduits, Timothy Watson, Adele Pope, Niels Van Pelt, Peter N Ruygrok

The Texas Heart Institute Journal

In coronary artery bypass grafting, good-quality conduits are needed to maximize the potential for long-term patency. Revascularization has traditionally been achieved with use of the saphenous vein and the internal thoracic arteries. In recent years, total arterial revascularization with use of the radial arteries has been promoted. Meanwhile, use of the transradial approach for coronary angiography has also increased. The long-term effects of previous cannulation in radial artery bypass grafts are not known. Therefore, we used multidetector computed tomographic angiography to investigate radial-artery graft patency in a small series of patients who had undergone transradial angiography. We found a high …

Combined Retrograde/Antegrade Approach To Transcatheter Closure Of An Aortic Paravalvular Leak, Abdulla A Damluji, Husnu E Kaynak, Alan W Heldman

The Texas Heart Institute Journal

New interventional techniques have made transcatheter closure of aortic paravalvular leaks a viable therapeutic option to treat the sequelae of these defects, including congestive heart failure and hemolysis. We report the transcatheter closure of an aortic paravalvular leak via a combined retrograde/antegrade approach. This was necessary because of difficulty in crossing the defect with a sheath from the retrograde approach. This technique might be useful in application to other difficult structural heart interventions. To our knowledge, this is the first report of a treated paravalvular leak around a Mitroflow(®) Aortic Pericardial Heart Valve.

Relationships Between Positive Psychological Constructs And Health Outcomes In Patients With Cardiovascular Disease: A Systematic Review, Christina M. Dubois, Oriana Vesga Lopez, Eleanor E. Beale, Brian C. Healy, Julia K. Boehm, Jeff C. Huffman

Psychology Faculty Articles and Research

Depression and anxiety are well-known to be associated with adverse health outcomes in cardiac patients. However, there has been less work synthesizing the effects of positive psychological constructs (e.g., optimism) on health-related outcomes in cardiac patients. We completed a systematic review of prospective observational studies using established guidelines. A search of PubMed and PsycINFO databases from inception to January 2014 was used to identify articles. To be eligible, studies were required to assess effects of a positive psychological construct on subsequent health-related outcomes (including mortality, rehospitalizations, self-reported health status) in patients with established heart disease. Exploratory random effects' meta-analyses were …

Objectives
In Western contexts nut consumption is associated with better health. We examined the associations of nut consumption with cardiovascular disease risk in the non-Western setting of Southern China.

Methods
In the Guangzhou Biobank Cohort Study we used multivariable linear regression to examine the associations of baseline nut (mainly peanuts) consumption (none (n = 6688),/ week (n = 2596) and _3 portions/week (n = 2444)) with follow-up assessment of Framingham cardiovascular disease score (excluding smoking) and its components in older Chinese (_50 years) (follow-up 57.8%).

Results
Nut consumption was not associated with Framingham score (_3 portions/week compared to none: 0.02 …

Risk Of Death From Cardiovascular Disease Associated With Low-Level Arsenic Exposure Among Long-Term Smokers In A Us Population-Based Study, Shohreh F. Farzan, Yu Chen, Judy R. Rees, M. Scot Zens, Margaret Karagas

Dartmouth Scholarship

High levels of arsenic exposure have been associated with increases in cardiovascular disease risk. However, studies of arsenic’s effects at lower exposure levels are limited and few prospective studies exist in the United States using long-term arsenic exposure biomarkers. We conducted a prospective analysis of the association between toenail arsenic and cardiovascular disease mortality using longitudinal data collected on 3939 participants in the New Hampshire Skin Cancer Study. Using Cox proportional hazard models adjusted for potential confounders, we estimated hazard ratios and 95% confidence intervals associated with the risk of death from any cardiovascular disease, ischemic heart disease, and stroke, …
