One of the noninvasive methods of evaluating left ventricular performance is the measurement of left ventricular systolic time intervals (LVSTI). However, noninvasive measurement of right ventricular systole by this technique has been unreliable because of the inability to accurately time the onset of right ventricular ejection. Excellent correlation of LVSTI measured from the carotid pulse and...

conclusions the patient underwent surgery several days later with complete resection of the tumor and coronary stent retrieval but his left ventricular ejection fraction remained poor after several months and he was referred for cardiac transplantation. introduction cardiac inflammatory myofibroblastic tumor is a rare tumor that can cause potentially fatal outcomes. case presentation we describ...

Introduction: It is well known that the tendency toward thrombosis is increased in cancer patients. The increase in cancer procoagulant and tissue factor levels, endothelial damage, and stasis due to compression are among the most accused causes of thrombosis in cancer patients. Hypereosinophilia is a rare condition that causes endothelial damage leading to thrombosis. <s...

OBJECTIVE To assess whether the 90 minute corrected thrombolysis in myocardial infarction frame count (CTFC) in the infarct related artery predicts left ventricular function at 48 hours in patients with myocardial infarction treated with aspirin, streptokinase, and either heparin or Hirulog. DESIGN AND SETTING Analysis of 251 patients with acute myocardial infarction enrolled in the internati...

In our earlier study, idiopathic dilated cardiomyopathy patients with persistently high serum troponin T (TnT) concentrations had notably depressed left ventricular ejection fractions, increased left ventricular diastolic dimensions, and adverse long term outcomes. Therefore, TnT seems to be a marker of ongoing subclinical myocyte injury, although the mechanism of its release is unknown. Most p...

BACKGROUND Drugs with negative inotropic effect are widely used to decrease obstruction in hypertrophic cardiomyopathy (HCM). However, the mechanism of therapeutic benefit has not been studied. METHODS AND RESULTS We used M-mode, two-dimensional, and pulsed Doppler echocardiography to study 11 patients with obstructive HCM before and after medical elimination of left ventricular outflow tract...

BACKGROUND The index of myocardial performance has prognostic power in patients with cardiomyopathy and following myocardial infarction. As the index of myocardial performance has been shown to be preload and afterload dependent, the effect of altering contractility on IMP and its components with left ventricular dysfunction has been incompletely delineated. METHODS Chronic left ventricular d...

OBJECTIVE Successful revascularization of chronic total occlusions has been associated with improved left ventricular systolic function, reduced anginal symptoms, increased exercise capacity, and increased survival. This study was conducted to determine the impact of revascularization in chronic total occlusion on left ventricular function using novel echocardiographic techniques. METHODS A t...

recognition of the natural history and responsible leading factors for regression of left ventricular hypertrophy after successful renal transplantation are very important. the aim of this study was to assess the regression of left ventricular hypertrophy after successful renal transplantation among uremic patients. in this study 27 uremic patients (18 males and 9 females) with an average age o...
