BACKGROUND: In the general population, even mild renal disease is associated with increased cardiovascular (CV) complications. Whether this is true in liver transplant recipients (LTR) is unknown. METHODS: This was a retrospective cohort study of 671 LTR (2002-2012) from a large urban tertiary care center and 37,322 LTR using Vizient hospitalization data linked to the United Network for Organ Sharing. The MDRD4 equation estimated GFR (eGFR). Outcomes were 1-year CV complications (death/hospitalization from myocardial infarction, heart failure, atrial fibrillation, cardiac arrest, pulmonary embolism or stroke) and mortality...

Standard therapies for heart failure with preserved ejection fraction (HFpEF) have been unsuccessful, demonstrating that the contribution of the underlying diastolic dysfunction pathophysiology differs from that of systolic dysfunction in heart failure and currently is far from being understood. Complicating the investigation of HFpEF is the contribution of several comorbidities. Here, we selected three established rat models of diastolic dysfunction defined by three major risk factors associated with HFpEF and researched their commonalities and differences...

BACKGROUND: DNA methylation-based patterns of biological aging, known as epigenetic age acceleration, are predictive of all-cause mortality, but little is known about their association with cardiovascular disease (CVD). METHODS: We estimated 2 versions of epigenetic age acceleration (Horvath and Hannum) using whole-blood samples from 2543 blacks. Linear and Cox proportional hazards regression, respectively, were used to assess the association of age acceleration with carotid intima-media thickness (cross-sectionally) and incident cardiovascular events, including CVD mortality, myocardial infarction, fatal coronary heart disease, peripheral arterial disease, and heart failure, during a median 21-year follow-up...

Objectives: Patients with RA display greater occult coronary atherosclerosis burden and experience higher cardiovascular morbidity and mortality compared with controls. We here explored whether pro-inflammatory cytokines and high-sensitivity cardiac troponin I (hs-cTnI), a biomarker of myocardial injury, correlated with plaque burden and cardiovascular events (CVEs) in RA. Methods: We evaluated 150 patients with 64-slice coronary CT angiography. Coronary artery calcium, number of segments with plaque (segment involvement score), stenotic severity and plaque burden were assessed...

Acute coronary syndrome usually presents with retrosternal chest pain, nausea, vomiting, sweating, and jaw and arm pain. Some patients only present with neck, epigastric, or ear discomfort. A 47-year-old male with a history of hypertension and coronary artery disease presented to the emergency department complaining of bilateral otalgia. He never felt chest pain, jaw pain, nausea, diaphoresis, or shortness of breath. He had a history of 2 acute coronary events and had a stress test 2 months prior to admission, which was unremarkable...

Myocardial infarction (MI) leads to cardiomyocyte loss, impaired cardiac function, and heart failure. Molecular genetic analyses of myocardium in mouse models of ischemic heart disease have provided great insight into the mechanisms of heart regeneration, which is promising for novel therapies after MI. Although biomechanical factors are considered an important aspect in cardiomyocyte proliferation, there are limited methods for mechanical assessment of the heart in the mouse MI model. This prevents further understanding the role of tissue biomechanics in cardiac regeneration...

Congestive heart failure (CHF) is a complicated pathophysiological syndrome, leading cause of hospitalization as well as mortalities in developed countries wherein an irregular function of the heart leads to the insufficient blood supply to the body organs. It is an accumulative slackening of various complications including myocardial infarction (MI), coronary heart disease (CAD), hypertension, valvular heart disease (VHD) and cardiomyopathy; its hallmarks include hypertrophy, increased interstitial fibrosis and loss of myocytes...

Interleukin-1 (IL-1) is the prototypical pro-inflammatory cytokine that occupies an apical place in the inflammatory cascade and also modulates cardiac function, functioning as a soluble cardiodepressant factor. Preclinical research over the past 4 decades has shown that blocking IL-1 processing or activity favorably affects cardiomyocyte survival and cardiac function in experimental animal models, paving the way for clinical studies in patients with heart disease. The promising results of phase II clinical trials of IL-1 blockade in patients with acute myocardial infarction and heart failure have been followed by a successful phase III trial in patients with prior acute myocardial infarction...

The Completeness of Revascularization in patients with multivessel coronary artery disease (CAD) remains an unanswered question. Despite 20 years of investigation there are still major doubts in this topic, reaching as far as to the lack of a standardized definition. The employment of different definition and the multiplicity of confounding variables that in general favor patients who receive a complete revascularization (CR) are the reason of difficult comparisons between studies. The complexity of coronary anatomy diseases and the clinical features play important role in the revascularization strategy...

BACKGROUND: Angiotensin receptor neprilysin inhibitor (ARNi) enhances beneficial natriuretic peptides by inhibiting their breakdown through neprilysin. Although the first-in-class ARNi sacubitril/valsartan (LCZ696) reduced mortality and morbidity in heart failure (HF) with reduced ejection fraction (EF) compared to angiotensin converting enzyme inhibitor (ACEi), mechanistic data on ARNi are scarce. ARNi may be superior to ACEi in attenuating adverse cardiac remodeling and dysfunction post-myocardial infarction (MI)...

BACKGROUND: Cardiovascular disease (CVD) is a leading cause of post-liver transplant death, and variable care patterns may affect outcomes. We aimed to describe epidemiology and outcomes of inpatient CVD care across U.S. hospitals. METHODS: Using a merged dataset from the 2002-2011 Nationwide Inpatient Sample and the American Hospital Association Annual Survey, we evaluated liver transplant patients admitted primarily with myocardial infarction (MI), stroke (CVA), congestive heart failure (CHF), dysrhythmias, cardiac arrest (CA), or malignant hypertension...

AIMS: Coronary microvascular dysfunction (CMD) is common in patients with non-obstructive coronary arteries but has not been described in low-risk symptomatic patients. We therefore assessed the prevalence and characteristics of CMD in low to moderate risk patients with chest pain in an emergency department. METHODS AND RESULTS: We used three-dimensional Rb82 cardiac positron emission tomography/computed tomography to diagnose coronary artery disease (known or new regional defect, any coronary calcification) and CMD (low coronary flow reserve without coronary artery disease) in chest pain patients after being ruled out for acute myocardial infarction...

Importance: Hospitals in the United States have been subject to mandatory public reporting of mortality rates for acute myocardial infarction (AMI) and heart failure (HF) since 2007 and to value-based payment programs for these conditions since 2011. However, whether hospitals with initially poor baseline performance have improved relative to other hospitals under these programs, and whether patterns of improvement differ by condition, is unknown. Understanding trends within public reporting and value-based payment can inform future efforts in these areas...

BACKGROUND: Women have higher rates of all-cause mortality after percutaneous coronary intervention. Whether this is because of greater age and comorbidity burden or a sex-specific factor remains unclear. METHODS AND RESULTS: We retrospectively assessed cause-specific long-term mortality after index percutaneous coronary intervention over 3 time periods (1991-1997, 1998-2005, and 2006-2012). Cause of death was determined using telephone interviews, medical records, and death certificates...

BACKGROUND: Hospital readmission rates are publicly reported by the Centers for Medicare & Medicaid Services (CMS); however, the implications of emergency department (ED) visits following hospital discharge on readmissions are uncertain. We describe the frequency, diagnoses, and hospital-level variation in ED visitation following hospital discharge, including the relationship between risk-standardized ED visitation and readmission rates. METHODS: This is a cross-sectional analysis of Medicare beneficiaries hospitalized for acute myocardial infarction (AMI), heart failure, and pneumonia between July 2011 and June 2012...

Heart failure (HF) is a leading cause of morbidity and mortality in the western world. Although optimal medical care and treatment is widely available, the prognosis of patients with HF is still poor. Toll-like receptors (TLRs) are important compartments of the innate immunity. Current studies have identified TLRs as critical mediators in cardiovascular diseases. In the present study, we investigated the involvement of TLRs and interferon (IFN) regulatory factors (IRFs) in different experimental HF models including viral myocarditis, myocardial ischemia, diabetes mellitus, and cardiac hypertrophy...

BACKGROUND: Caloric restriction (CR) has been described to have cardioprotective effects and improve functional outcomes in animal models and humans. Chronic ischemic heart failure (HF) is associated with reduced cardiac sympathetic innervation, dysfunctional β-adrenergic receptor signaling, and decreased cardiac inotropic reserve. We tested the effects of a long-term CR diet, started late after myocardial infarction on cardiac function, sympathetic innervation, and β-adrenergic receptor responsiveness in a rat model of postischemic HF...

Background -The effect of HIV on the development of peripheral artery disease (PAD) remains unclear. We investigated whether HIV infection is associated with an increased risk of PAD after adjustment for traditional atherosclerotic risk factors in a large cohort of HIV infected (HIV+) and demographically similar HIV uninfected veterans. Methods -We studied participants in the Veterans Aging Cohort Study from April 1, 2003 through December 31, 2014. We excluded participants with known prior PAD or prevalent cardiovascular disease (myocardial infarction, stroke, coronary heart disease, and congestive heart failure) and analyzed the effect of HIV status on the risk of incident PAD events after adjusting for demographics, PAD risk factors, substance use, CD4 cell count, HIV-1 RNA, and antiretroviral therapy...
