Mechanisms Of Left Ventricular Thrombus Formation In Heart Failure With Reduced Ejection Fraction: Novel Insights From Two-Dimensional Speckle Tracking Echocardiography, Dhruv Chawla, Tracy Hammonds, Tadele Mengesha, Matt Umland, Khawaja Afzal Ammar, Vinay Thohan
Journal of Patient-Centered Research and Reviews
Background: Patients suffering from heart failure with reduced ejection fraction (HFrEF) are at increased risk for left ventricular (LV) thrombus and subsequent thromboembolism, yet anticoagulation is not routinely recommended for left ventricular ejection fraction (LVEF) alone. We sought to determine the role of two-dimensional speckle tracking echocardiography (2D-STE) to quantify regional changes in cardiac function associated with LV thrombus, which may prospectively guide anticoagulation.
Purpose: Help enable cardiovascular clinicians to use 2D-STE to evaluate regional strain patterns among patients with HFrEF with and without LV thrombus. Our results suggest that statistically lower regional longitudinal strain patterns in a well-matched cohort ...
Assessment Of Chronic Disease To Determine Appropriateness Of Implantable Cardioverter-Defibrillator Therapy, 2017 Aurora Cardiovascular Services
Assessment Of Chronic Disease To Determine Appropriateness Of Implantable Cardioverter-Defibrillator Therapy, Bilal M. Omery, Maharaj Singh, Randy S. Turkel, Robyn Shearer, Arshad Jahangir, M. Eyman Mortada, Jasbir S. Sra, Indrajit Choudhuri
Journal of Patient-Centered Research and Reviews
Background: Implantable cardioverter-defibrillator (ICD) therapy is considered appropriate when a patient is felt to have a reasonable expectation of 1-year survival. Chronic diseases have been estimated to be associated with greater than 10% annual mortality and may reduce benefits of ICD therapy. Frailty has been estimated to be associated with greater than 20% annual mortality and has been suggested to contraindicate ICD therapy.
Purpose: Determine a risk score that may identify patients in whom ICD implantation may not be appropriate.
Methods: Patients who received an ICD for primary and secondary prevention from 2008 through 2013 at the Aurora Health Care ...
A Historical Perspective On Presentations Of Hypertensive Acute Heart Failure, 2017 University of Massachusetts Medical School
A Historical Perspective On Presentations Of Hypertensive Acute Heart Failure, Chad E. Darling, Jiaoyuan Elisabeth Sun, Jordan Goldberg, Peter Pang, Christopher W. Baugh, Darleen M. Lessard, David D. Mcmanus
David D. McManus
BACKGROUND: The initial systolic blood pressure (SBP) in patients presenting to the hospital with acute heart failure (AHF) informs prognosis, diagnosis, and guides initial treatment. However, over time AHF presentations with elevated SBP appear to have declined. The present study examined whether the frequency of AHF presentations with systolic hypertension (SBP > 160 mmHg) declined over a nearly two-decade time interval. METHODS: This study compares four historical, cross-sectional cohorts with AHF who were admitted to tertiary care medical centres in the North-eastern USA in 1995, 2000, 2006, and 2011-13. The main outcome was the proportion of AHF patients presenting with an ...

University of Massachusetts Medical School Faculty Publications
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 ...

Dilated cardiomyopathy (DCM) is an important cause of heart failure. Single gene mutations in at least 50 genes have been proposed to account for 25–50% of DCM cases and up to 25% of inherited DCM has been attributed to truncating mutations in the sarcomeric structural protein titin (TTNtv). Whilst the primary molecular mechanism of some DCM-associated mutations in the contractile apparatus has been studied in vitro and in transgenic mice, the contractile defect in human heart muscle has not been studied. In this study we isolated cardiac myofibrils from 3 TTNtv mutants, and 3 with contractile protein mutations (TNNI3 ...

UMass Worcester PRC Publications
BACKGROUND: Among women aged 50 to 59 years at baseline in the Women's Health Initiative (WHI) Estrogen-Alone (E-Alone) trial, randomization to conjugated equine estrogen-alone versus placebo was associated with lower risk of myocardial infarction and mortality, and, in an ancillary study, the WHI-CACS (WHI Coronary Artery Calcification Study) with lower CAC, measured by cardiac computed tomography approximately 8.7 years after baseline randomization. We hypothesized that higher CAC would be related to post-trial coronary heart disease (CHD), cardiovascular disease (CVD), and total mortality, independent of baseline randomization or risk factors.
METHODS AND RESULTS: WHI-CACS participants (n=1020) were followed ...

Health Behavior Research
Due to disparities in stroke risk among U.S. Hispanics, the need for culturally tailored, theory based effective health behavior change interventions persists. The purpose of this study was to examine self-determination theory (SDT) constructs related to cardiovascular disease (CVD) risk factors in a predominantly Mexican American population. The Stroke Health and Risk Education (SHARE) project was a cluster-randomized, faith-based behavioral intervention trial that enrolled Mexican Americans (MAs) and non-Hispanic whites (NHWs) from Catholic Churches in Nueces County, Texas. Data regarding SDT constructs and dietary and physical activity behaviors were collected via computer-assisted interviews using standardized instruments at the baseline ...

Connection of the heart to the systemic circulation is a critical developmental event that requires selective preservation of embryonic vessels (aortic arches). However, why some aortic arches regress while others are incorporated into the mature aortic tree remains unclear. By microdissection and deep sequencing in mouse, we find that neural crest (NC) only differentiates into vascular smooth muscle cells (SMCs) around those aortic arches destined for survival and reorganization, and identify the transcription factor Gata6 as a crucial regulator of this process. Gata6 is expressed in SMCs and its target genes activation control SMC differentiation. Furthermore, Gata6 is sufficient to ...

Dietary changes are a major lifestyle factor that can influence the progression of chronic diseases such as diabetes. Recently, flavanols, a subgroup of plant-derived phytochemicals called flavonoids, have gained increasing attention, due to studies showing an inverse correlation between dietary intake of flavanols and incidence of diabetes. Flavanoids in the cocoa plant may ameliorate insulin resistance by improving endothelial function, altering glucose metabolism, and reducing oxidative stress. Oxidative stress has been proposed as the main culprit for insulin resistance. The well-established effects of cocoa on endothelial function also points to a possible effect on insulin sensitivity. The relationship between insulin ...

BACKGROUND: Children with heart disease may require repeated X-Ray cardiac catheterization procedures, are more radiosensitive, and more likely to survive to experience oncologic risks of medical radiation. Cardiovascular magnetic resonance (CMR) is radiation-free and offers information about structure, function, and perfusion but not hemodynamics. We intend to perform complete radiation-free diagnostic right heart catheterization entirely using CMR fluoroscopy guidance in an unselected cohort of pediatric patients; we report the feasibility and safety.
METHODS: We performed 50 CMR fluoroscopy guided comprehensive transfemoral right heart catheterizations in 39 pediatric (12.7 ± 4.7 years) subjects referred for clinically indicated cardiac catheterization. CMR ...
The Recognition Of Hpv Infection As A Risk Factor For Cardiovascular Disease In Men, 2017 Duquesne University
The Recognition Of Hpv Infection As A Risk Factor For Cardiovascular Disease In Men, Hayley Stettner
Graduate Student Research Symposium
Human papilloma virus (HPV) is the most common sexually transmitted infection. Strains 16 and 18 are causes of cervical, anogenital, and oropharyngeal cancer. A study found a nearly 3-fold increase in incidence of cardiovascular (CV) events, i.e. stroke and myocardial infarction (MI), in HPV-infected women. HPV-16 and 18 contain protein E6 that binds to p53 tumor suppressor protein, which aids in regulating atherosclerosis, and causes p53 protein degeneration. Additional studies have linked absence of p53 protein to accumulation of atherosclerosis in the body, which is the leading cause of CV events. Presented is a case of a 55-year old ...

African Americans have higher rates of mortality than whites who are the same age and sex. We hypothesize that in low socioeconomic status neighborhoods, having health insurance coverage and a regular health care provider increases the likelihood of receiving diagnostic tests for cardiovascular disease and diabetes. We use data from a random two-stage cluster sample of 230 adults living in high poverty census tracts to examine the effects of insurance coverage and having a regular doctor on the likelihood receiving diagnostic tests for high cholesterol, high blood sugar, and blood pressure. We find that health insurance coverage increases the odds ...

Statin-Associated Muscle Symptoms (Sams) In Primary Prevention For Cardiovascular Disease In Older Adults, Zhen Zhou, Loai Albarqouni, Monique Breslin, Andrea J. Curtis, Mark Nelson
Faculty of Health Sciences & Medicine Publications
INTRODUCTION: Although statins are commonly used for prevention of cardiovascular disease, there is limited evidence about statin-related adverse effects in older people. Statin-related adverse events (AEs), especially the statin-associated muscle symptoms (SAMS), are the most common reasons for their discontinuation. Therefore, it is important to determine the risk of SAMS in the older population. We will undertake a systematic review and meta-analysis primarily focusing on the risk of SAMS and secondarily targeting myopathy, rhabdomyolysis, AEs and serious AEs, dropouts due to SAMS in run-in period, related permanent discontinuation rate of statins and creatine kinase level, among older people who received ...
