The onset in elderly subjects of clinical signs of chronic venous insufficiency (CVI), without a previous history of venous disease of the lower limbs, raises questions about the etiology. In our study we evaluated the possible causes investigating the venous system of the lower limbs and right heart function in elderly subjects with signs of CVI. The alterations found were on the reduction of TAPSE, a significantly higher body mass index and a reduced ability to walk compared to the control group.

The purpose of this study was to determine whether only patients with insulin resistance also have an alteration of endothelial function assessed by ultrasound flow-mediated (FMD). In a population of 165 patients, 30 subjects had only a family history of diabetes and/or sporadic findings of hypoglycemia, and they were assessed for FMD, the glucose and insulin curve.

Methods And Results: Of the 26 male patients that were enrolled, 13 patients (26+/-8 years) suffered from acute myocarditis and 13 (25+/-2 years) were healthy participants (controls). Both patients and controls underwent cardiac magnetic resonance (CMR) and 2-dimensional S imaging (2D-S) echocardiography on the same day.
Ion channels are essential to a wide range of physiological functions including neuronal signaling, muscle contraction, cardiac pacemaking, hormone secretion and cell proliferation. Linking ion-channel gene mutations to inherited disorders has been described. Ankyrins are intracellular proteins required for the biogenesis and maintenance of membrane domains in both excitable and non-excitable cells.

Methods: In total, 72 consecutive patients (33 men) with a mean age of 49 +/- 13 years were prospectively enrolled. The TEE indication was cryptogenic stroke (36 patients) or migraine (36 patients, 22 with aura).
We greatly appreciated the letter to the Editor by Rana Olgunturk and Serdar Kula. We can say that his interpretation coincides with our interpretation and with the knowledge about patent ductus arteriosus (PDA) and secundum atrial septal defects. Although functional closure of PDA usually occurs in the first few hours of life in healthy infants born at term (about 15 h of life in healthy infants born at term), true anatomic closure, in which the ductus loses the ability to reopen, may take several weeks.

Subclinical hyperthyroidism is an increasingly recognized entity that is defined as a normal serum free thyroxine and free triiodothyronine levels with a TSH level suppressed below the normal range and usually undetectable. It has been reported that subclinical hyperthyroidism is not associated with coronary heart disease or mortality from cardiovascular causes but it is sufficient to induce arrhythmias including atrial fibrillation and atrial flutter.

With each systole, the coronary artery is compressed. The pathophysiology of myocardial bridging is incompletely understood.

Moreover, flow-mediated vasodilation in the brachial artery and intima media thickness (IMT) in the carotid artery could represent a surrogate diagnostic method for assessment of coronary artery disease (CAD) severity. Renal function is an important predictor of the presence and severity of angiographic CAD in patients without severe renal impairment with incremental value over traditional risk factors for CAD and IMT.

Aneurysms of the sinus of Valsalva are rare, most commonly involving the right or noncoronary sinuses. They can be congenital or acquired through infection, trauma, or degenerative diseases.

Dobutamine stress echocardiography (DSE) and Dobutamine-atropine stress echocardiography (DASE) have been studied. Handgrip (HG) exercise has been rarely studied in stress echocardiography.

Cardiac abnormalities in perinatal asphyxia include tricuspid regurgitation and mitral regurgitation associated with transient myocardial ischemia of the newborn. Patent foramen ovale is a frequent remnant of the fetal circulation.

The spectrum of potential clinical applications is very wide due to its ability to differentiate between active and passive movement of myocardial segments, to quantify intraventricular dyssynchrony and to evaluate components of myocardial function, such as longitudinal myocardial shortening, that are not visually assessable. In-vivo and in-vitro validation of 2D-strain imaging technique have been undertaken and reached a point where it is considered ready for more widespread investigations into clinical utility, e.
View Article and Find Full Text PDFAfter mechanical heart valve replacement use of unfractionated heparin is sometimes required because vitamin K antagonists are temporarily contraindicated or to prevent valve-associated thromboembolism until oral vitamin K antagonists take effect. Bridging therapy with a standardized low molecular weight heparin-based regimen has been reported effective and relatively safe in a large cohort of patients with mechanical heart valves. Many cases with mitral mechanical valve prostheses and treatment failure of low molecular weight heparin have also been reported as well as prosthetic valve thrombosis has been reported with adequate anticoagulation.
