BACKGROUND We sought to investigate the influence of the extent of myocardial injury on left ventricular (LV) systolic and diastolic function in patients after reperfused acute myocardial infarction (AMI). METHODS Thirty-eight reperfused AMI patients underwent cardiac magnetic resonance (CMR) imaging after percutaneous coronary revascularization. The extent of myocardial edema and scarring we...
BACKGROUND We investigated race-ethnic and sex-specific relationships of left ventricular (LV) structure and LV function in African American and white men and women at 43 to 55 years of age. METHODS AND RESULTS The Coronary Artery Risk Development in Young Adults (CARDIA) Study enrolled African American and white adults, age 18 to 30 years, from 4 US field centers in 1985-1986 (Year-0) who ha...
BACKGROUND Interest in the role of arterial stiffness in the pathomechanism of left ventricular (LV) diastolic dysfunction has grown in recent years. AIM To examine the relationship between local carotid arterial stiffness parameters assessed by the ultrasonic high-resolution echo-tracking (eT) method and LV diastolic function indices in patients with untreated hypertension (H). METHODS The...
OBJECTIVE To test the hypothesis that diastolic mitral annular motion velocity, as determined by Doppler tissue imaging and left ventricular diastolic flow propagation velocity, is related to the histological degree of heart transplant rejection according to the International Society of Heart and Lung Transplantation (ISHLT). METHODS In 41 heart transplant recipients undergoing 151 myocardial...
INTRODUCTION AND OBJECTIVES To evaluate ventricular function using Doppler echocardiography in patients with an atrial septal defect (ASD). METHODS The study involved 158 children, who were divided into two groups: Group 1 comprised 111 children with an ASD, and Group 2, 47 healthy children. Left ventricular systolic function was evaluated by measuring the ejection fraction, the shortening fr...
Background: The role of reactive oxygen species (ROS) in the pathogenesis of different cardiac diseases has been documented. Recently, effect of allopurinol in decreasing the production of ROS and improving cardiovascular pathogenesis has come into scientific interest. Animal studies have documented the benefit of allopurinol in improving left ventricular dilatation, hypertrophy and fibro...
PURPOSE To evaluate normal blood flow velocity and Doppler indices of the ophthalmic arteries from birth to hospital discharge of inborn infants at birth weights between 500 and 1500 g and gestational age <or=32 weeks. METHODS A longitudinal prospective study with Doppler ultrasound was conducted in both eyes at 24 hours, 7 and 28 days, and hospital discharge for systolic and diastolic veloci...
