Feasibility of Extended Ambulatory Electrocardiogram Monitoring to Identify Silent Atrial Fibrillation in High‐risk Patients: The Screening Study for Undiagnosed Atrial Fibrillation (STUDY‐AF)
ConclusionsOutpatient extended ECG screening for asymptomatic AF is feasible, with AF identified in 1 in 20 subjects and sustained AT/AF identified in 1 in 9 subjects, respectively. We also found a high prevalence of asymptomatic AT and frequent supraventricular ectopic complexes, which may be relevant to development of AF or stroke. If confirmed in a larger study, primary screening for AF could have a significant impact on public health. (Source: Clinical Cardiology)

Increased Transforming Growth Factor‐β Levels Associated With Cardiac Adverse Events in Hypertrophic Cardiomyopathy
ABSTRACT BackgroundHypertrophic cardiomyopathy (HCM) is a common genetic heart disease characterized by ventricular hypertrophy, myocardial fibrosis, and impaired ventricular relaxation. The exact mechanisms by which fibrosis is caused remain unknown. HypothesisCirculating TGF‐β is related to poor prognosis in HCM. MethodsWe compared TGF‐β levels of 49 HCM patients with those of 40 non‐HCM patients. We followed the patients with HCM for 18 months and divided them into 2 groups: low TGF‐β (≤4877 pg/mL) and high TGF‐β (>4877 pg/mL). We compared the 2 groups in terms of brain natriuretic pe...

Beneficial Effects of Positive Airway Pressure Therapy for Sleep‐Disordered Breathing in Heart Failure Patients With Preserved Left Ventricular Ejection Fraction
ABSTRACT BackgroundRight‐heart dysfunction is associated with poor prognosis in heart failure with preserved left ventricular ejection fraction (HFpEF). It remains unclear whether sleep‐disordered breathing (SDB) treatment using positive airway pressure (PAP) improves right‐heart and pulmonary function and exercise capacity and reduces mortality rates of HFpEF patients. HypothesisPAP may improve right‐heart and pulmonary function, exercise capacity and prognosis in HFpEF patients with SDB. MethodsOne hundred nine consecutive patients with HFpEF (left ventricular ejection fraction>50%) and moderate to severe SDB ...

Stem‐Cell Angiogenesis and Regeneration of the Heart: Review of a Saga of 2 Decades
ABSTRACT Advances in the novel approach to control ischemic heart disease and heart failure using stem cells or progenitor cells from bone marrow, mesenchyme, or myocardial tissue itself have demonstrated efficacy for increasing left ventricular function, decreasing infarct scar tissue, improving exercise tolerance and heart failure symptoms, and, in some studies, decreasing mortality and reducing rehospitalization for intractable angina or subsequent myocardial infarction. The most common techniques utilize injections of cells into the coronary vasculature or directly into specific areas of vulnerable myocardium. Although...

Reducing Cardiovascular and Cancer Risk: How to Address Global Primary Prevention in Clinical Practice
Abstract Emerging evidence suggesting the possibility that interventions able to prevent cardiovascular disease (CVD) may also be effective in the prevention of cancer have recently stimulated great interest in the medical community. In particular, data from both experimental and observational studies have demonstrated that aspirin may play a role in preventing different types of cancer. Although the use of aspirin in the secondary prevention of CVD is well established, aspirin in primary prevention is not systematically recommended because the absolute cardiovascular event reduction is similar to the absolute excess in ma...

Cholesterol, Statins, and Dementia: What the Cardiologist Should Know
Abstract Alzheimer dementia (AD) is an important clinical problem that appears to be closely tied to comorbid cardiovascular disease, making it a relevant topic for the clinical cardiologist. Determinants of cardiovascular health, especially midlife dyslipidemia, are associated with an increased risk of dementia based on molecular and epidemiologic data. Given the potential role of dyslipidemia in the development of dementia, statins have been investigated as potential therapeutic options to slow or prevent disease. This review discusses the role of dyslipidemia and other cardiovascular risk factors in the pathogenesis of ...

Echocardiographic and Biohumoral Characteristics in Patients With AL and TTR Amyloidosis at Diagnosis
ConclusionsOur data show that at time of first diagnosis, TTR patients have a more advanced amyloidotic involvement of the heart, despite less severe symptoms and biohumoral signs of heart failure. We can hypothesize that we observed different diseases at different stages. In fact, AL amyloidosis is a multiorgan disease with quick progression rate, that becomes rapidly symptomatic, whereas TTR amyloidosis might have a slow progression rate and might remain poorly symptomatic for a greater amount of time.

Prognostic Implications of Low Level Cardiac Troponin Elevation Using High‐Sensitivity Cardiac Troponin T
ABSTRACT BackgroundHigh‐sensitivity cardiac troponin T (hsTnT) is used in many countries, but is not available in the United States. Prior evidence has been viewed as inconclusive as to whether low cardiac troponin T (cTnT) concentrations detected with hsTnT are prognostically meaningful compared with fourth‐generation cTnT. HypothesisThe aim of this study was to assess the prognostic performance of low‐level cTnT elevations using the hsTnT assay compared with the assay (fourth‐generation) currently available in the United States. MethodsWe measured serum cTnT in 4160 patients with non–ST‐elevation acute co...

The Value of Magnetic Resonance Imaging in Catheter Ablation of Atrial Fibrillation
Abstract Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Catheter ablation is now a recognized treatment for those with symptomatic AF refractory to drug therapy. Innovations in magnetic resonance imaging (MRI) have empowered clinicians to improve ablation efficacy while reducing the risk of complications. It is demonstrated that late gadolinium enhancement MRI has additional advantages over modalities such as echocardiography and computed tomography, due to its ability to assess the structural remodeling directly. As a result, MRI has become an indispensable imaging tool to persona...

Abstract Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia in the United States and worldwide.

Abstract BackgroundThere is little research on overall cardiovascular (CV) health among couples. Our aim was to examine concordance levels for CV health among couples, using the American Heart Association ideal health metrics, and to investigate if the CV health of an individual is associated with that of his or her partner. HypothesisThere is a positive association between the overall cardiovascular health of an individual and that of his/her partner. MethodsThe Mitchelstown Study is a community‐based cohort study of middle‐aged Irish adults. Potential couples were identified as 2 study participants living at the same...

Outcomes Associated With Preoperative Use of Extracorporeal Membrane Oxygenation in Children Undergoing Heart Operation for Congenital Heart Disease: A Multi‐institutional Analysis
This study was designed to evaluate this association using the Pediatric Health Information System (PHIS) database. HypothesisWe hypothesize that patients receiving ECMO prior to heart operation will have worse outcomes, including mortality, compared with patients receiving ECMO after heart operation. MethodsPatients age ≤18 years receiving ECMO before or after pediatric heart operation (with or without cardiopulmonary bypass) at a PHIS‐participating hospital from 2004 to 2013 were included. Multivariable logistic regression or Cox proportional‐hazards models were fitted to study the effect of timing of ECMO ...
