It is estimated that in the United States, each year, approximately 620,000 persons will experience an acute coronary syndrome and approximately 70% of these will have non-ST-elevation acute coronary syndrome. Cardiovascular disease still accounts for 1 of every 3 deaths in the United States, and there is an urgent need to improve the prognosis of patients presenting with acute coronary syndrome. Cardiovascular mortality and ischemic complications are common after acute coronary syndrome, and the advent of newer antithrombotic therapies has reduced ischemic complications, but at the expense of greater bleeding...

BACKGROUND: Pulmonary hypertension (PH) and right ventricular (RV) dysfunction are strong predictors of morbidity and mortality among patients with congenital heart disease. Early detection of RV involvement may be useful in the management of these patients. We aimed to assess progressive cardiac adaptation and quantify myocardial extracellular volume in an experimental porcine model of PH because of aorto-pulmonary shunt using cardiac magnetic resonance (CMR). METHODS AND RESULTS: To characterize serial cardiac adaptation, 12 pigs (aorto-pulmonary shunt [n=6] or sham operation [n=6]) were evaluated monthly with right heart catheterization, CMR, and computed tomography during 4 months, followed by pathology analysis...

INTRODUCTION AND OBJECTIVES: Area at risk (AAR) quantification is important to evaluate the efficacy of cardioprotective therapies. However, postinfarction AAR assessment could be influenced by the infarcted coronary territory. Our aim was to determine the accuracy of T2-weighted short tau triple-inversion recovery (T2W-STIR) cardiac magnetic resonance (CMR) imaging for accurate AAR quantification in anterior, lateral, and inferior myocardial infarctions. METHODS: Acute reperfused myocardial infarction was experimentally induced in 12 pigs, with 40-minute occlusion of the left anterior descending (n = 4), left circumflex (n = 4), and right coronary arteries (n = 4)...

BACKGROUND: There are scant outcomes data in patients with type 2 diabetes and stable coronary artery disease (CAD) stratified by detailed angiographic burden of CAD or left ventricular ejection fraction (LVEF). OBJECTIVES: This study determined the effect of optimal medical therapy (OMT), with or without percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG), on long-term outcomes with respect to LVEF and number of diseased vessels, including proximal left anterior descending artery involvement...

BACKGROUND: The optimal method of coronary revascularization among patients with diabetes mellitus (DM) and multivessel coronary artery disease (CAD) complicated by chronic kidney disease (CKD) remains unknown. PURPOSE: To examine the impact of coronary artery bypass surgery (CABG) vs. percutaneous coronary intervention (PCI) on cardiovascular outcomes in patients with diabetes with and without CKD. METHODS: We conducted an 'as-treated' subgroup analysis of the FREEDOM trial to examine the therapeutic efficacy of CABG vs...

BACKGROUND: The 2013 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines recommend primary prevention with statins for individuals with ≥7.5% 10-year risk for atherosclerotic cardiovascular disease (ASCVD). Everyone living long enough will become eligible for risk-based statin therapy due to age alone. OBJECTIVES: This study sought to personalize ACC/AHA risk-based statin eligibility using noninvasive assessment of subclinical atherosclerosis...

BACKGROUND: The importance of a healthy diet in relation to cardiovascular health promotion is widely recognized. Identifying specific dietary patterns related to early atherosclerosis would contribute greatly to inform effective primary prevention strategies. OBJECTIVES: This study sought to quantify the association between specific dietary patterns and presence and extent of subclinical atherosclerosis in a population of asymptomatic middle-aged adults. METHODS: The PESA (Progression of Early Subclinical Atherosclerosis) study enrolled 4,082 asymptomatic participants 40 to 54 years of age (mean age 45...

BACKGROUND: Although guideline-recommended therapies reduce major adverse cardiovascular events (MACE) in patients after myocardial infarction (MI) or those with atherosclerotic disease (ATH), adherence is poor. OBJECTIVES: The goal of this study was to determine the association between medication adherence levels and long-term MACE in these patients. METHODS: We queried the claims database of a large health insurer for patients hospitalized for MI or with ATH...

INTRODUCTION AND OBJECTIVES: To estimate the health benefits and cost-effectiveness of a polypill intervention (aspirin 100 mg, atorvastatin 20 mg, ramipril 10 mg) compared with multiple monotherapy for secondary prevention of cardiovascular events in adults with a history of myocardial infarction from the perspective of the Spanish National Health System. METHODS: An adapted version of a recently published Markov model developed and validated in Microsoft Excel was used to compare the cost-effectiveness of the polypill with that of its combined monocomponents over a 10-year time horizon...

BACKGROUND: Hypertension is the leading global risk for mortality. Poor treatment and control of hypertension in low- and middle-income countries is due to several reasons, including insufficient human resources. Nurse management of hypertension is a novel approach to address the human resource challenge. However, specific barriers and facilitators to this strategy are not known. OBJECTIVE: To evaluate barriers and facilitators to nurse management of hypertensive patients in rural western Kenya, using a qualitative research approach...

Atrial fibrillation (AF) is a complex phenomenon associated with electrical, mechanical, and structural abnormalities of the atria. Ischaemic stroke in AF is only partially understood, but the mechanisms are known to be related to the atrial substrate as well as the atrial rhythm. The temporal dissociation between timing of AF and occurrence of stroke has led to the hypothesis that fibrotic, prothrombotic atrial tissue is an important cause of thrombus formation in patients with AF, independent of the atrial rhythm...

Cardiovascular disease remains the leading cause of death worldwide, particularly in low- and middle-income countries (LMICs), with substantial mortality from acute coronary syndromes. These deaths, when compared against high-income countries, occur at younger ages, and, beyond the lives lost, often result in economic privation for families deprived of a breadwinner and indebted by the oftentimes catastrophic cost of inpatient medical care. This burden will likely grow in scale in the years ahead as more countries pass through the epidemiologic transition...

Endothelial to mesenchymal transition (EndMT) plays a major role during development, and also contributes to several adult cardiovascular diseases. Importantly, mesenchymal cells including fibroblasts are prominent in atherosclerosis, with key functions including regulation of: inflammation, matrix and collagen production, and plaque structural integrity. However, little is known about the origins of atherosclerosis-associated fibroblasts. Here we show using endothelial-specific lineage-tracking that EndMT-derived fibroblast-like cells are common in atherosclerotic lesions, with EndMT-derived cells expressing a range of fibroblast-specific markers...

Beta-3 adrenergic receptor (β3AR) agonists have been shown to produce vasodilation and prevention of ventricular remodeling in different conditions. Given that these biological functions are critical in pulmonary hypertension (PH), we aimed to demonstrate a beneficial effect of β3AR agonists in PH. An experimental study in pigs (n = 34) with chronic PH created by pulmonary vein banding was designed to evaluate the acute hemodynamic effect and the long-term effect of β3AR agonists on hemodynamics, vascular remodeling and RV performance in chronic PH...

BACKGROUND: Prognosis in pulmonary hypertension (PH) is related to right ventricular (RV) function. Quantification of RV mechanics may offer additive value. The objective of our study is to determine the feasibility and clinical and prognostic value of RV strain analysis by cardiovascular magnetic resonance (CMR) based feature tracking (FT) in PH. METHODS: We retrospectively enrolled 116 patients (age 52.2 ± 12 years, 73.6 % women) referred to CMR for PH evaluation who underwent right heart catheterization within 1 month...
