The role of urate and xanthine oxidase in vascular oxidative stress:Future directions [PDF]

, 2009
Vascular oxidative stress has been shown to be a potent factor in the pathophysiology of endothelial dysfunction. Despite current optimal evidence-based therapy, mortality from various cardiovascular disorders remains high.

PDE2 activity differs in right and left rat ventricular myocardium and differentially regulates β2 adrenoceptor-mediated effects [PDF]

, 2015
The important regulator of cardiac function, cAMP, is hydrolyzed by different cyclic nucleotide phosphodiesterases (PDEs), whose expression and activity are not uniform throughout the heart. Of these enzymes, PDE2 shapes β1 adrenoceptor-dependent cardiac

Noninvasive Evaluation of Cardiac Function in Non Hypertensive and Asymptomatic Diabetic Patients [PDF]

Background & Objectives: Type 2 diabetes is a major cardiovascular risk factor such as HTN, HLP and smoking. A primary diabetic cardiomyopathy represents a high risk factor for heart failure in the absence of ischemic, valvular and hypertensive heart ...

Perfusion of the interventricular septum during ventilation with positive end-expiratory pressure (PEEP) [PDF]

, 1991
Objective: To determine whether regional hypoperfusion of the interventricular septum occurs during ventilation with positive end-expiratory pressure. Design: Animal study. Animals: Anesthetized, closed chest dogs (n = 8).

Atrial cellular electrophysiological changes in patients with ventricular dysfunction may predispose to AF [PDF]

, 2009
<b>Background:</b> Left ventricular systolic dysfunction (LVSD) is a risk factor for atrial fibrillation (AF), but the atrial cellular electrophysiological mechanisms in humans are unclear.

Left ventricular function in acute inflammatory peri-myocardial diseases – new insights and long-term follow-up

Cardiovascular Ultrasound, 2012
Background Until recently acute inflammatory peri-myocardial syndromes have been associated with global rather regional left ventricular (LV) dysfunction. Recent advances in cardiac imaging with echocardiographic techniques and magnetic resonance imaging

Left atrial reservoir strain as a predictor for left ventricular filling pressure in patients with sinus rhythm

Scientific Reports
We aimed to evaluate the utility of left atrial reservoir strain (LASr) as a predictor of left ventricular (LV) filling pressure measured via catheterization in patients with sinus rhythm.

The brain in heart failure [PDF]

, 2004
After atrial fibrillation, heart failure is the second most frequent cardiac association of stroke. Deteriorating left ventricular systolic function appears to increase the risk of cardioembolic stroke in heart failure.
