BACKGROUND AND OBJECTIVES The hemodialysis procedure may acutely induce regional left ventricular systolic dysfunction. This study evaluated the prevalence, time course, and associated patient- and dialysis-related factors of this entity and its association with outcome. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Hemodialysis patients (105) on a three times per week dialysis schedule were ...

s Objectives: The aim of this study is to show the effects of left ventricular hypertrophy and geometric patterns on the left ventricular diastolic function in patients with essential hypertension. In addition, it’s aimed to identify whether the diastolic dysfunction is associated with systolic dysfunction. Finally, to determine the occurrence of the diastolic dysfunction in hypertensive patien...

BACKGROUND Screening for patients with asymptomatic left ventricular dysfunction is of considerable importance because they may benefit from early treatment with angiotensin converting enzyme inhibitors. It has been suggested that atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and cyclic guanosine 3',5'-monophosphate (cGMP) might be useful markers for screening. OBJECTIVE ...

Premature ventricular complexes (PVCs) in the absence of structural heart disease are often, but not always benign. They may require treatment for symptoms produced by the PVCs themselves or for intermittent sustained ventricular tachycardia. Even in the absence of symptoms, frequent premature ventricular complexes may lead to the development of left ventricular systolic dysfunction as a form o...

Objective To assess the prevalence and clinical characteristics of left ventricular dysfunction among elderly patients in the general practice setting by echocardiographic assessment of ventricular function. Design Cross sectional survey. Setting Four centre general practice in Poole, Dorset. Subjects 817 elderly patients aged 70-84 years. Main outcomes Echocardiographic assessment of left vent...

To determine the effects of chronic nonocclusive coronary constriction on cardiac hemodynamics, structural integrity, and contractile protein enzyme activity, the left coronary artery was narrowed in rats, and measurements of ventricular performance, magnitude, and distribution of tissue damage and myofibrillar Mg2+ and Ca2+ myosin ATPase activities were evaluated 1 month later. In the presence...
