Vascular Effects of Eplerenone in Coronary Artery Disease With Preserved Ejection Fraction: A Double‐Blind, Randomized, Placebo‐Controlled Trial
ConclusionsAdding low‐dose eplerenone to standard medical therapy did not improve important markers of vascular health in patients with CAD and preserved EF. Our results may help understand conflicting evidence from larger clinical trials on MRAs in patients with preserved EF. (Source: Clinical Cardiology)

Effect of Remote Ischaemic Conditioning in Oncology Patients Undergoing Chemotherapy: Rationale and Design of the ERIC‐ONC Study—A Single‐Center, Blinded, Randomized Controlled Trial
ABSTRACT Cancer survival continues to improve, and thus cardiovascular consequences of chemotherapy are increasingly important determinants of long‐term morbidity and mortality. Conventional strategies to protect the heart from chemotherapy have important hemodynamic or myelosuppressive side effects. Remote ischemic conditioning (RIC) using intermittent limb ischemia‐reperfusion reduces myocardial injury in the setting of percutaneous coronary intervention. Anthracycline cardiotoxicity and ischemia‐reperfusion injury share common biochemical pathways in cardiomyocytes. The potential for RIC as a novel treatment to re...

Management Strategies and Outcomes of ST‐Segment Elevation Myocardial Infarction Patients Transferred After Receiving Fibrinolytic Therapy in the United States
ABSTRACT Fibrinolytic therapy is still used in patients with ST‐segment elevation myocardial infarction (STEMI) when the primary percutaneous coronary intervention cannot be provided in a timely fashion. Management strategies and outcomes in transferred fibrinolytic‐treated STEMI patients have not been well assessed in real‐world settings. Using the Nationwide Inpatient Sample from 2008 to 2012, we identified 18 814 patients with STEMI who received fibrinolytic therapy and were transferred to a different facility within 24 hours. The primary outcome was in‐hospital mortality. Secondary outcomes included gastrointes...

The Role of the Myocardial Microvasculature in Mental Stress–Induced Myocardial Ischemia
This study is a review of the literature discussing the prevalence and emerging mechanisms underlying MSIMI. We identified several aspects underlying MSIMI, including psychological, genetic, and physiological causes. Several sources suggested that dysfunctional cardiac microvasculature might be a contributing factor in the development of stress‐induced myocardial ischemia. The literature also suggested that although MSIMI has distinct features and pathophysiology, its occurrence might indicate an increased future risk of cardiovascular events. We found that dysfunctional cardiac microvasculature may be the key point of i...

Comparison of Coronary Artery Disease Consortium 1 and 2 Scores and Duke Clinical Score to Predict Obstructive Coronary Disease by Invasive Coronary Angiography
ABSTRACT BackgroundThe first step in evaluating a patient with suspected stable coronary artery disease (CAD) is the determination of the pretest probability. The European Society of Cardiology guidelines recommend the use of the CAD Consortium 1 score (CAD1), which contrary to CAD Consortium 2 (CAD2) score and Duke Clinical Score (DCS), does not include modifiable cardiovascular risk factors. HypothesisUsing scores that include modifiable risk factors (DCS and CAD2) enhances prediction of CAD.

Barthel Index as a Predictor of 1‐Year Mortality in Very Elderly Patients Who Underwent Percutaneous Coronary Intervention for Acute Coronary Syndrome: Better Activities of Daily Living, Longer Life
ABSTRACT BackgroundPercutaneous coronary intervention (PCI) is safe and effective in very elderly patients, defined as those who are age ≥85 years, with acute coronary syndrome (ACS). However, the prognostic factors remain unknown. The association between activities of daily living (ADL) and the prognosis after PCI has not yet been investigated.

HypothesisAP prevalence is similar in those with vs without DM in a community sample with CAD.

Exercise and Physical Activity for the Post–Aortic Dissection Patient: The Clinician's Conundrum
ABSTRACT Despite the paucity of evidence, it is often presumed, and is physiologically plausible, that sudden, acute elevations in blood pressure may transiently increase the risk of recurrent aortic dissection (AD) or rupture in patients with a prior AD, because a post‐dissection aorta is almost invariably dilated and may thus experience greater associated wall stress as compared with a nondilated aorta. Few data are available regarding the specific types and intensities of exercise that may be both safe and beneficial for this escalating patient population. The purpose of this editorial/commentary is to further explore...

HypothesisIn the acute coronary syndrome (ACS) symptom complex, sweating can differentiate ST‐segment elevation myocardial infarction (STEMI) from non–ST‐segment elevation ACS (NSTE‐ACS) during early hours of infarction. MethodsThis single‐center, prospective, observational study compared symptoms of STEMI and NSTE‐ACS patients admitted from August 2012 to July 2014.

Intra‐abdominal Hypertension: An Important Consideration for Diuretic Resistance in Acute Decompensated Heart Failure
ABSTRACT Fluid accumulation is the hallmark of heart failure decompensation. Fluid overload and congestion are associated with recurrent hospitalizations, poor quality of life, and increased mortality in heart failure. Despite the use of high‐dose intravenous loop diuretic therapy, acutely decompensated heart failure patients may develop diuretic resistance. Diuretic refractoriness can be a result of elevated intra‐abdominal pressure (IAP) in acutely decompensated heart failure. Increased renal venous and interstitial pressures in patients with elevated IAP may lead to renal impairment and diuretic resistance. Routine ...

Speckle Tracking Echocardiography of the Right Atrium: The Neglected Chamber
ABSTRACT The right atrium (RA) plays a pivotal role in electromechanical and endocrine regulation of the heart. Its peculiar anatomical features and phasic mechanical function make it distinct from ventricles. Various invasive and noninvasive techniques have been used to elucidate RA structure and function. Of these modalities, echocardiography has distinct advantages over others. Several conventional measures of RA function through echocardiography have been described in the literature, but they are load dependent. A relatively new technique is speckle tracking–derived strain, which is relatively less dependent on l...

Rationale, Design, and Methodological Aspects of the BUDAPEST‐GLOBAL Study (Burden of Atherosclerotic Plaques Study in Twins—Genetic Loci and the Burden of Atherosclerotic Lesions)
ABSTRACT The heritability of coronary atherosclerotic plaque burden, coronary geometry, and phenotypes associated with increased cardiometabolic risk are largely unknown. The primary aim of the Burden of Atherosclerotic Plaques Study in Twins—Genetic Loci and the Burden of Atherosclerotic Lesions (BUDAPEST‐GLOBAL) study is to evaluate the influence of genetic and environmental factors on the burden of coronary artery disease. By design this is a prospective, single‐center, classical twin study. In total, 202 twins (61 monozygotic pairs, 40 dizygotic same‐sex pairs) were enrolled from the Hungarian Twin Registry...

Ranolazine in Cardiac Arrhythmia
ABSTRACT Ranolazine utilization in the management of refractory angina has been established by multiple randomized clinical studies. However, there is growing evidence showing an evolving role in the field of cardiac arrhythmias. Multiple experimental and clinical studies have evaluated the role of ranolazine in prevention and management of atrial fibrillation, with ongoing studies on its role in ventricular arrhythmias. In this review, we will discuss the pharmacological, experimental, and clinical evidence behind ranolazine use in the management of various cardiac arrhythmias. (Source: Clinical Cardiology)

Remnant Lipoprotein Cholesterol and Mortality After Acute Myocardial Infarction: Further Evidence for a Hypercholesterolemia Paradox From the TRIUMPH Registry
We examined 2465 AMI survivors in a prospective, 24‐center US study of AMI outcomes. Lipoprotein cholesterol subfractions were directly measured by ultracentrifugation. RLP‐C was defined as intermediate‐density lipoprotein cholesterol (IDL‐C) + very‐low‐density lipoprotein cholesterol subfraction 3 (VLDL3‐C). Given a linear relationship between RLP‐C and mortality, we examined RLP‐C by tertiles and continuously. Cox regression hazard ratios (HRs) were adjusted for the Global Registry of Acute Coronary Events (GRACE) score and 23 other covariates. ResultsParticipants were age 58 ± 12 years (mean &pl...
