Background: Aluminum phosphide (known as rice tablet) toxicity is a serious, fatal poisoning despite the advancement of intensive care. Phosphine gas, released after exposure of aluminum phosphide to gastric acidic content, causes mortal systemic toxicity. Multi-organ failure may progress within the first hours of severe toxicity. Refractory hypotension, cardiac shock and metabolic acidosis a...
Background and Objective: Various biomarkers lead to the incidence of pathologic left ventricular hypertrophy such as Cardiotrophin-1. The aim of the present study was to investigate the impact of 12 weeks of aerobic exercise on serum levels of cardiotrophin-1, blood pressure and left ventricular hypertrophy in hypertensive elderly women. Materials and Methods: In this study, 40 women age...
Background: Cardiotoxicity of anthracyclines (ANTs) in medium and high doses (more than 350 mg/m2) has been already known but it is still unclear whether or not minimal doses (lower than 350 mg/m2) can also affect cardiac function. The goal of this study was to assess the cardiotoxicity of ANTs in children under minimal doses and evaluation the association of this toxicity with probable risk fa...
introduction: chest x–ray is one of the most common method of imaging. cardio thoracic ratio ( ctr ) is one of the parameters of chest x–ray that is used for determining cardiac enlargement. echocardiography as compared to chest x–ray is expensive and all centers dont have it, but it can determine heart size, valvular diseases, ejection fraction, left ventricular hypertrophy (lvh), pericardial ...
introduction: cardiovascular abnormalities have been reported in liver cirrhosis (lc). in these patients, cardiac symptoms and physical signs occur as the liver functions worsen. cirrhosis is associated with hyper dynamic circulation and beta-adrenergic system changes responsible for the cardiovascular abnormalities. the purpose of the present study was to explore the echocardiographic findings...
Background Peak oxygen consumption is reduced in patients with symptomatic congestive heart failure, but functional capacity of patients with asymptomatic left ventricular systolic dysfunction has not been assessed by measurement of peak oxygen consumption attained during graded exercise testing. Methods and Results Peak oxygen consumption, that is, aerobic capacity (Vo2, mL/kg per minute), was...
Neuroendocrine activation is known to occur in patients with congestive heart failure, but there is uncertainty as to whether this occurs before or after the presence of overt symptoms. In the Studies of Left Ventricular Dysfunction (SOLVD), a multicenter study of patients with ejection fractions of 35% or less, we compared baseline plasma norepinephrine, plasma renin activity, plasma atrial na...
Preoperative left ventricular systolic function is an important predictor of postoperative prognosis in patients with aortic regurgitation. Although left ventricular dysfunction is reversible after aortic valve replacement to a greater extent in patients with good preoperative exercise capacity compared with patients with impaired exercise capacity, not all patients with preserved exercise capa...
myocardial dysfunction is a major complication in cardiac surgery that needs inotropic support. this study evaluates the effect of milrinone on patients with low ventricular ejection fraction undergoing off- pump coronary artery bypass graft (opcab). the present study is designed to evaluate the effect of milrinone on myocardial dysfunction. eighty patients with low ventricular ejection fractio...
