TL;DR: The American College of Cardiology (ACC)/American Heart Association (AHA) Task Force on Practice Guidelines regularly reviews existing guidelines to determine when an update or full revision is needed.

TL;DR: Evaluated diagnostic accuracy of multislice computed tomography (MSCT) coronary angiography using a new 64-slice scanner indicates high quantitative and qualitative diagnostic accuracy in comparison to QCA in a broad spectrum of patients.

TL;DR: Patients presenting with PA experienced more cardiovascular events than did EHT patients independent of blood pressure, and the presence of PA should be detected, not only to determine the cause of HTN, but also to prevent such complications.

TL;DR: Data suggest that AIx might be a more sensitive marker of arterial stiffening and risk in younger individuals but aortic PWV is likely to be a better measure in older individuals.

TL;DR: New approaches to improve the delivery of behavioral services and patient adherence to behavioral recommendations are reviewed, based on the understanding that psychosocial and behavioral risk factors for CAD are not only highly interrelated, but also require a sophisticated health care delivery system to optimize their effectiveness.

TL;DR: In this article, the diagnostic accuracy of 64-slice computed tomography (CT) to identify and quantify atherosclerotic coronary lesions in comparison with catheter-based angiography and intravascular ultrasound (IVUS) was evaluated.

TL;DR: Exercise produces a short-term, inflammatory response, whereas both cross-sectional comparisons and longitudinal exercise training studies demonstrate a long-term "anti-inflammatory" effect, which may contribute to the beneficial effects of habitual physical activity.

TL;DR: The electron beam CT coronary calcium score predicts CAD events independent ofstandard risk factors, more accurately than standard risk factors and CRP, and refines Framingham risk stratification.

TL;DR: In this article, the diagnostic accuracy of cardiovascular magnetic resonance (CMR) imaging in distinguishing pathological left ventricular non-compaction (LVNC) from lesser degrees of trabecular layering seen in healthy volunteers and, in those with cardiomyopathies and concentric left-ventricular hypertrophy, potential differential diagnoses was evaluated.

TL;DR: Total WBC count is confirmed to be an independent predictor of death/MI in patients with or at high risk for CAD, but greater predictive ability is provided by high N (Q4 >6.6 x 10(3)/microl) or low L counts.

TL;DR: There is a considerable risk of stent fractures after long segment femoral artery stenting, which is associated with a higher in-stent restenosis and reocclusion rate.

TL;DR: The novel finding is that new-onset AF and associated stroke were significantly reduced by losartan- compared to atenolol-based antihypertensive treatment with similar blood pressure reduction.

TL;DR: Clinical trials are needed to define whether hyporesponders to clopidogrel are at increased risk for thrombotic events and whether hyper-responders are at increase risk for bleeding.

TL;DR: Atherothrombosis is a complex disease in which cholesterol deposition, inflammation, and thrombus formation play a major role, and the role of eccentric remodeling, vasa vasorum neovascularization, and mechanisms of plaque rupture are systematically evaluated.

TL;DR: The STI estimation of LVtor is concordant with those analyzed by tagged MRI and also showed good agreement with those by DTI (data derived from tissue velocity) and may make the assessment more available in clinical and research cardiology.

TL;DR: In this article, a systematic review of the literature was performed to identify all reports of the effect of ACEIs or ARBs on the development of atrial fibrillation (AF) and to identify patient subgroups most likely to benefit.

TL;DR: A combined CMR approach using T2-weighted imaging, early and late gadolinium enhancement, provides a high diagnostic accuracy and is a useful tool in the diagnosis and assessment of patients with suspected acute myocarditis.

TL;DR: In this article, the predictors of stent thrombosis after sirolimus-eluting stent (SES) implantation were determined. But, their results were limited to 15 patients who developed STC after successful SES implantation.

TL;DR: Depletion of circulating EPCs in diabetic patients may be involved in the pathogenesis of peripheral vascular complications and, for the first time, show that PVD is associated with an extensively low number of E PCs.

TL;DR: Percutaneous edge-to-edge mitral valve repair can be performed safely and a reduction in MR can be achieved in a significant proportion of patients to six months.

TL;DR: Therapy with either a natriuretic peptide or vasodilator was associated with significantly lower in-hospital mortality than positive inotropic therapy in patients hospitalized with ADHF.

TL;DR: Angiographically proven late stent thrombosis occurs with an incidence of at least 0.35% (95% confidence limits 0.17% to 0.72%) in patients treated with DES, and may also occur when patients are stable on antiplatelet monotherapy.

TL;DR: Whether home telemonitoring (HTM) improves outcomes compared with nurse telephone support and usual care for patients with heart failure who are at high risk of hospitalization or death is sought.

TL;DR: Surgical myectomy performed to relieve outflow obstruction and severe symptoms in HCM was associated with long-term survival equivalent to that of the general population, and superior to obstructive HCM without operation.

TL;DR: This classification of sports has been developed to allow a fundamental question to be addressed: whether it is reasonably safe to recommend that an athlete with a specific cardiovascular abnormality be eligible for a particular competitive sport.

TL;DR: Significant race and gender differences exist in the population distribution of C-reactive protein (CRP) levels, and whether thresholds for cardiovascular risk assessment should be adjusted for differentrace and gender groups is investigated.

TL;DR: Clot strength is more predictive than ADP-induced platelet aggregation and may explain the occurrence of events despite treatment with cyclooxygenase-1 and P2Y12 inhibitors.

TL;DR: There is no clearly demonstrable mortality benefit conferred by MVA for significant MR with severe LV dysfunction, and a prospective randomized control trial is warranted for further study of mortality with MVA in this population.

TL;DR: Despite presenting with higher risk characteristics and having higher in-hospital risk, women with NSTE ACS are treated less aggressively than men.

TL;DR: It is concluded that 99mTc-DPD scintigraphy is a useful step in the workup of the differential diagnosis of TTR versus AL etiology in patients with documented cardiac amyloidosis.
