TL;DR: In this paper, the authors determined the prevalence of AF from 1968 to 1989 in the Framingham Study cohort aged 65 to 84 years and evaluated the prevalence by sex and in the presence of VHD, prior MI, and CHF.

TL;DR: The evidence of the important two-way clinical correlation between cancer and venous thromboembolism dates back to Trousseau's time and there is growing evidence for their possible benefits in terms of cancer prognosis and patient survival.

TL;DR: The magnitude and the pattern of these velocities are significantly altered by age and by left ventricular hypertrophy, which provides a new insight into diastolic filling events and may prove useful in detecting abnormal diastolics function.

TL;DR: It is concluded that wall velocities obtained by pulsed Doppler tissue imaging are accurate and reproducible and may prove useful for studying the contractile and elastic properties of the myocardium.

TL;DR: Depression is reduced in patients with symptomatic coronary heart disease patients enrolled in cardiac rehabilitation and exercise training and exhibited statistically greater improvements in certain behavioral and quality-of-life parameters than did nondepressed patients.

TL;DR: In this paper, the MB isoenzyme of creatine kinase (MBCK) was measured to improve the ability to detect cardiac injury in patients with blunt chest trauma, 44 patients were studied.

TL;DR: TDI has potential to quantitatively assess regional left ventricular function and Calculated systolic and early diastolic posterior wall TDI indexes correlated significantly with percentage of wall thickening.

TL;DR: Radiofrequency AV-junctional catheter ablation and pacing is a highly successful form of treatment for medically refractory atrial fibrillation and Congestive heart failure episodes decreased from 18 before to 8 afterward.

TL;DR: Malondialdehyde concentrations in the plasma of patients with congestive heart failure having varying degrees of clinical symptoms and in control subjects were significantly higher than those in the control group, supporting the hypothesis that the CHF state and underlying risk conditions appear to be associate with abnormal oxidative stress.

TL;DR: Altered cICAM-1 and sL-selectin levels in patients with coronary artery disease reflect the presence of a chronic inflammatory process, which results in downregulation of leukocyte expression of L- Selectin and thus lower circulating s L- selectin levels.

TL;DR: In this paper, the authors assessed standard 12-lead and Holter electrocardiographic (ECG) abnormalities in maintenance hemodialysis (HD) patients and found that the prevalence of ECG changes correlated inversely with HD duration.

TL;DR: In this article, the role of risk factors for atherosclerosis as it relates to EDRF was examined and it was shown that abnormal endothelium-dependent relaxation has been demonstrated in hypercholesterolemic patients with little or no evidence of coronary angiographic disease.

TL;DR: Patients with a large degree of shunt across a patient foramen ovale, as determined by contrast transesophageal echocardiography, are at a significantly higher risk of subsequent adverse neurologic events compared with patients with a small degree ofShunt.

TL;DR: It is concluded that PESDA microbubbles alone may be capable of inducing thrombolysis when insonified with a low-frequency transducer.

TL;DR: The results suggest that endothelial dysfunction exists in patients with hypertension and precedes overt atherosclerotic disease, and isosorbide dinitrate-induced changes were similar.

TL;DR: In this paper, the authors investigated the role of endogenous adrenomedullin in the pathophysiology of acute myocardial infarction (AMI) in 15 consecutive patients with 15 healthy control subjects.

TL;DR: In this paper, the authors focus on evolving models of anticoagulation management with the potential for improving the safety, efficacy, and cost-effectiveness of therapy and removing potential barriers to treatment.

TL;DR: The proposed analysis system provided accurate measurements of phantom dimensions and can be used to perform highly reproducible area and volume measurements in three-dimensional ICUS in vivo.

TL;DR: The occurrence of myocardial infarction demonstrates marked circadian, day-of-week, and seasonal variations, with some differences between working and retired patients, which may aid in identifying underlaying mechanisms and perhaps in improving prevention of the disease.

TL;DR: EBCT is not sufficiently reproducible to allow serial quantitation of coronary calcium in individual patients over relatively short periods (< 2 years), and Reproducibility for all three image-acquisition protocols was low; however, the 20-slice 6 mm slice thickness protocol gave reproducibility superior to either of the 3mm slice thickness protocols.

TL;DR: The results of this study narrow the anatomic location for radiofrequency ablation of idiopathic RVOT ventricular tachycardia to the anterior superior aspect of the RVOT determined by fluoroscopic imaging.

TL;DR: It is concluded that (1) myocardial velocities rapidly decrease during acute ischemia and show a rebound increase after reperfusion, and (2) in regions remote from ischemIA, velocITIES display distinct patterns on the basis of the presence or absence of obstructive coronary disease in the associated vessel.

TL;DR: The field of local drug delivery is currently under investigation in association with radiation or molecular therapy, and the current specific target of these approaches is the neointimal proliferation, especially because this is the most dominant mechanism of restenosis after stent placement.

TL;DR: In this paper, the effect of terfenadine on the QT interval corrected for heart rate (QTc) of the scalar electrocardiogram (ECG) was investigated.

TL;DR: When atherosclerotic aortic debris is detected, especially if the debris is mobile, substituting brachial for femoral catheterization and avoiding placement of an intraaortic balloon pump may reduce the risk of embolism.

TL;DR: It is concluded that the plasma levels of B-type or brain natriuretic peptide are increased in the majority of patients with unstable angina and that the increased levels decrease toward normal after treatment.

TL;DR: In this paper, T. cruzi antigens were detected in 10 (71%) of 14 regions with histopathologic evidence of moderate or severe myocarditis and 3 of 18 regions with only mild or absent Myocarditis.

TL;DR: In this paper, enalapril or placebo was administered in a double-blind fashion to 6797 participants with ejection fraction < or = 0.35, and 28.1% of participants randomized to enalAPril reported side effects compared with 16.0% in the placebo group.

TL;DR: Medical therapy appears to be effective and safe in infants with SVT and radiofrequency ablation should be reserved for rare infants who fail aggressive medical regimens or when the situation is complicated by ventricular dysfunction, severe symptoms, or complex congenital heart disease.
