TL;DR: Mitral E velocity, corrected for the influence of relaxation (i.e., the E/Ea ratio), relates well to mean PCWP and may be used to estimate LV filling pressures.

TL;DR: In this article, the prevalence of aortic sclerosis and stenosis in the elderly and to identify clinical factors associated with degenerative aortric valve disease were determined using stepwise logistic regression analysis.

TL;DR: In this article, the authors assessed the clinical utility of mitral annulus velocity in the evaluation of left ventricular diastolic function and found that mitral velocity determined by DTI is a relatively preload-independent variable in evaluating diASTolic function.

TL;DR: A simplified approach to understanding the process of diastolic filling of the left ventricle and interpreting the Doppler flow velocity curves as they relate to this process is presented.

TL;DR: Current management strategies of acute major pulmonary embolism are largely dependent on the degree of hemodynamic instability at presentation, and physicians often rely on the findings of bedside echocardiography and proceed to thrombolytic treatment without seeking further diagnostic certainty in nuclear imaging or angiographic studies.

TL;DR: With experience, procedural and clinical outcomes of PTCA were similar for the three subgroups, but access failure is more common during transradial P TCA.

TL;DR: Spectrum of Clinicopathologic Manifestations of Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia: A Multicenter study as mentioned in this paper was conducted to investigate the effect of arrhythmogenic right ventricular arrhythmia.

TL;DR: Sudden cardiac arrest usually occurs at home, and the survival of those with a witnessed SCA at home was low compared with that outside the home, indicating the necessity of optimizing out-of-hospital resuscitation, especially in the at-home situation.

TL;DR: The investigation of potential tachycardia-induced cardiomyopathy in patients with heart failure requires further prospective confirmation in larger numbers of patients, with study of mechanisms, patient groups affected and optimal therapies.

TL;DR: C Cyanosis, operative experience of the surgeon and an RV outflow tract patch influence long-term outcome after repair of TOF in older children, and thus heart monitoring should be intensified.

TL;DR: The recent demonstration that endothelial dysfunction may be reversible raises the possibility of slowing the progression of atherosclerosis or modifying arterial function, or both, to decrease the risk of acute cardiovascular events.

TL;DR: Multivariate analysis demonstrated that diabetes mellitus, placement of multiple stents and minimal lumen diameter (MLD) immediately after stenting were the strongest predictors of restenosis.

TL;DR: An irregular sequence of RR intervals produces adverse hemodynamic consequences that are independent of heart rate, and is compared with VVI pacing at the same average rate.

TL;DR: Comprehensive heart failure management led to improved functional status and an 85% decrease in the hospital admission rate for transplant candidates discharged after evaluation, which suggests that referral to a heart failure program may be appropriate not only for potential heart transplantation, but also for medical management of persistent functional class III and IV heart failure.

TL;DR: Pooled analysis of 37 studies showed that although all techniques accurately identify segments with improved contractile function after revascularization, the Tl-201 protocols may overestimate functional recovery.

TL;DR: A high VE-VCO2 slope selects patients with more severe heart failure and is an independent prognostic marker in the assessment of patients with chronic heart failure.

TL;DR: CHF is associated with marked insulin resistance, characterized by both fasting and stimulated hyperinsulinemia, but this is not directly mediated through ventricular dysfunction or increased catecholamine levels.

TL;DR: In this article, the authors discuss the known cardiovascular effects of smoking and the effects of nicotine without tobacco smoke and interpret the available data on cardiovascular risk during nicotine replacement therapy (NRT).

TL;DR: Long-term right ventricular apical pacing resulted in a high incidence of myocardial perfusion defects that increased with the duration of pacing, which was associated with apical wall motion abnormalities and impaired global left ventricular function.

TL;DR: The ratio of component velocity (E) over the color M-mode propagation velocity during early LV filling, by correcting for the effect of LV relaxation, provides a better estimate of pw than standard measurements of transmitral Doppler flow.

TL;DR: Dobutamine stress echocardiography (DSE) is a useful, feasible and safe exercise-independent stress modality for assessing the presence, localization and extent of CAD.

TL;DR: Ongoing loss of sinus rhythm and late peaks in the risk of atrial flutter and death necessitate continued follow-up in children who underwent the Mustard operation.

TL;DR: The reduction ofCD11b expression and inhibition of CD11b-dependent monocyte adhesion to endothelium may crucially contribute to the clinical benefit of HMG-CoA reductase inhibitors in CHD, independent of cholesterol-lowering effects.

TL;DR: In this article, the authors evaluated whether troponin T might be used for identification of patients with unstable coronary artery disease in whom treatment with low molecular weight heparin is beneficial.

TL;DR: Measurement of serum levels of cTnT provides evidence of myocyte injury in patients with clinically suspected myocarditis more sensitively than does conventional determination of cardiac enzyme levels.

TL;DR: Tc-99m sestamibi SPECT perfusion imaging shows a significantly better specificity, which is further enhanced by the use of ECG gating, than Tl-201 SPECT studies, which had a similar sensitivity for the detection of CAD in women.

TL;DR: In this paper, the authors characterized the contemporary relation between diabetes and outcome after myocardial infarction treated with thrombolytic agents from a large international cohort and found that patients with diabetes alone and in association with its comorbidities, portends a substantially worse 30-day and 1-year prognosis for patients with myocardious infarctions.

TL;DR: Exposure to amiodarone in this dose range, for a minimal duration of 12 months, resulted in odds similar to those of placebo for hepatic and gastrointestinal adverse effects, but in significantly higher odds than those of Placebo for experiencing thyroid adverse effects.

TL;DR: In this paper, a substudy of the Australia-New Zealand trial of carvedilol in patients with heart failure due to ischemic heart disease was conducted to determine the effects of this treatment on left ventricular size and function with the use of quantitative two-dimensional (2D) echocardiography.

TL;DR: In this article, the authors examined the clinical predictors and angiographic and clinical outcomes associated with atrial fibrillation in the setting of acute myocardial infarction (MI).
