Introduction: The correlation between right and left ventricular ejection fractions (RVEF and LVEF, respectively) has been studied in only a small number of patients with a marked decrease in RVEF and LVEF. The aim of the present study was to compare LVEF and RVEF in patients with ischemic heart disease. RVEF and LVEF were measured by Cardiovascular Magnetic Resonance (CMR) imaging. Materials a...

Atrial tachy-pacing was performed in 34 patients who were divided into 3 groups as follows. Group I: 4 patients with obscure chest pain syndromes and normal coronary arteries and haemodynamics; Group 2: 25 patients with significant coronary artery disease and angina pectoris; Group 3: 5 patients with coronary artery disease, left ventricular aneurysm, and left ventricular dysfunction. Pacing pr...

We studied the effect of nitroprusside on the hydraulic vascular load of the right and left ventricle in seven patients with severe left ventricular failure. At doses of 0.25-0.75 micrograms/kg/min, stroke volume increased progressively from 40.1 to 48.6 ml and left ventricular end-diastolic pressure decreased from 24.5 to 11.2 mm Hg. Accompanying this improvement in left ventricular performanc...

we assessed different systolic cardiac indices to detect left and right ventricular systolic dysfunction in cirrhotic patients before liver transplantation. between 2010-2011, 81 consecutive individuals with confirmed hepatic cirrhosis who were a candidate for liver transplantation were enrolled in this study. a total of 32 age and sex matched healthy volunteers were also selected as the contro...

Left ventricular performance was determined by echocardiography in 44 black children with homozygous sickle cell anaemia and a control group of 28 normal black children of comparable age. Statistically significant differences were observed between the children with sickle cell anaemia and the normal group in left ventricular ejection fraction (sickle cell anaemia group: 0-59 + 0.01 [mean + stan...

Background: The cardiac effects simultaneously occurring during experimental hypertension and diabetes have rarely been investigated. This study aimed at examining the effects of short-term renovascular hypertension and type 2 diabetes on cardiac functions. Methods: Five groups (7 each) of male Sprague-Dawley rats, including a control group, a diabetes (induced by Streptozocin and Nicotinamide)...

conclusions in the setting of acute left ventricular function depression in hocm, a comprehensive differential diagnosis should be established. treatment should be based on hemodynamic changes. after recovery, the prognosis is related to hocm. case presentation we present a unique case where tks occurred in a middle-aged male patient with hypertrophic obstructive cardiomyopathy (hocm) without a...

Background and Aims: Cardiac hypertrophy is a compensatory augmentation response of the heart due to pressure overload that can lead to heart failure. Carvacrol is considered as the major compound of many plants, that possesses strong antioxidant properties. The present study aimed to evaluate effect of carvacrol on catalase activity and mRNA expression following left ventricular hypertrop...

OBJECTIVE To compare clinical and haemodynamic variables between left ventricular and biventricular pacing in patients with severe heart failure; and to analyse haemodynamic changes during daily life and maximum exercise during chronic left ventricular and biventricular pacing. DESIGN Prospective single blinded randomised study with crossover. SETTING University hospital (tertiary referral ...
