BACKGROUND Increased left ventricular mass (LVM) by echocardiography is associated with increased risk of cardiovascular disease. Thus, it is of interest to compare the effects of both pharmacological and nonpharmacological approaches to the treatment of hypertension on reduction of LVM. METHODS AND RESULTS Changes in LV structure were assessed by M-mode(More)
OBJECTIVES This study sought to assess the effects of sequential coronary artery occlusion during minimally invasive coronary artery bypass graft surgery (CABG) on hemodynamic variables and left ventricular systolic function by means of transesophageal echocardiography (TEE). BACKGROUND Clinical and experimental studies suggest a protective effect of(More)
Transesophageal echocardiography (TEE) has been used over the last 10 years (1982-1992) to study the heart and thoracic aorta. We set out to evaluate the diagnostic applications of TEE in patients with thoracic trauma. Specifically, TEE was performed on patients suspected of having either a cardiac contusion or an injury of the thoracic aorta. Fifty-eight(More)
BACKGROUND Echocardiography provides a noninvasive means of assessing left ventricular (LV) structure and evidence of LV wall remodeling in hypertensive persons. The relation of demographic, biological, and other factors with LV structure can be assessed. METHODS AND RESULTS LV structure was assessed by M-mode echocardiograms for 511 men and 333 women(More)
BACKGROUND AND PURPOSE We know that significant cardiac involvement can occur in patients with acute intracranial hemorrhage, particularly in those with subarachnoid hemorrhage. These patients may present with electrocardiographic abnormalities that were previously thought to be benign. However, many die of cardiovascular sequelae, which suggests more(More)
Right atrial myxoma is a rare cause of heart failure in infancy and childhood. 1-4 Since its clinical diagnosis is elusive in this age group,4 it is usually not suspected in the differential diagnosis of cyanotic neonates with congestive cardiac failure. The implications, however, of making the diagnosis of this potentially curable tumour during life are(More)
The effect of general anesthesia on the severity of mitral regurgitation (MR) was examined in 43 patients with moderate or severe MR who underwent preoperative and intraoperative transesophageal echocardiography. Systolic blood pressure, mean arterial pressure, and left ventricular end-diastolic and end-systolic dimensions were significantly lower during(More)
Antihypertensive therapy in hypertensive patients with left ventricular (LV) hypertrophy causes hypertrophy regression and improved diastolic filling. Whether similar changes occur in hypertensive patients with diastolic dysfunction and no hypertrophy is unknown. We determined the effect of antihypertensive therapy of LV geometry and function in(More)
Echocardiography is becoming commonplace in clinical trials relating to hypertension for assessing changes in left ventricular mass (LVM). Factors affecting variability need to be considered in the design and management of such studies. These include (1) standardization of recordings and readings, (2) quality of recordings, (3) choice of sonographer vs.(More)
