AIM Chronic heart failure is associated with endothelial dysfunction and insulin resistance. The aim of this investigation was to study insulin-stimulated endothelial function and glucose uptake in skeletal muscles in patients with heart failure in comparison to patients with type 2 diabetes. METHODS Twenty-three patients with systolic heart failure and no history of diabetes, seven patients ...

It is estimated that 30% to 50% of heart failure patients have preserved systolic left ventricular (LV) function, often referred to as diastolic heart failure (DHF). Mortality is high in this patient population, and morbidity and rate of hospitalization are similar to those of patients with systolic heart failure. The management of patients with diastolic heart failure is essentially empirical,...

Urocortin (UCN), a member of the corticotrophin-releasing factor family, is expressed in heart, brain and gut. UCN has potent cardiostimulatory, cardioprotective, vasodilator and diuretic/natriuretic effects, and cardiac UCN expression is increased in heart failure (HF). In the present study, we investigated plasma levels of UCN in 119 patients with HF and 212 age- and gender-matched controls t...

Many patients with acute heart failure have marked hypertension and preserved left ventricular ejection fraction. In these patients, the heart failure usually does not result from transient systolic dysfunction or valvular abnormalities but rather results from diastolic dysfunction. Treatment of this condition includes control of hypertension, cautious diuresis, and, if necessary, ventilatory s...

Heart failure has traditionally been thought of as a typically male problem. However, while women with heart failure have been little represented in clinical trials (0%-32%) and are not so often seen in cardiology units, over half of all patients with this syndrome including over half of those admitted to hospital because of it are women.1 Women with heart failure are usually older than men2; i...

Pharmacological therapy of systolic left ventricular dysfunction has evolved over the past 3 decades. Current therapy is focused primarily on the regulation of the renin-angiotensin-aldosterone axis and sympathetic nervous system. Additional targets of pharmacotherapy include vasoconstriction, impaired nitric oxide metabolism, inflammation and improving myocardial function. As therapies in chro...

AIMS Hypertrophic cardiomyopathy (HCM) is an important cause of heart failure-related disability over a wide range of ages. Profiles of severe progressive heart failure symptoms and death, or heart transplantation deserve more complete definition within large patient cohorts. METHODS AND RESULTS Clinical and morphological features of heart failure were assessed in 293 consecutive HCM patients...

BACKGROUND Human urotensin II (UTN) has potent vasoactive and cardiostimulatory effects, acting on the G protein-linked receptor GPR14. Myocardial UTN expression is upregulated in heart failure, and UTN stimulates myocardial expression of the natriuretic peptides. We investigated plasma UTN levels in heart failure (HF; left ventricular systolic dysfunction) in comparison with plasma N-terminal ...

Physiological principles that directly apply to physical diagnosis provide opportune occasions to bring basic science to the bedside. In this article, we describe the effect of cardiac maneuvers on systolic murmurs and how physiological principles apply to the explanation of the changes noted at the bedside. We discuss the effect of Valsalva, squatting, and hand grip maneuvers on different phys...
