Risk of Hemorrhage on Warfarin
In this study, the authors attempt to develop a risk stratification score to predict bleeding in patients treated with warfarin oral anticoagulation. -
BUN and High-Dose Loop Diuretics
High-dose loop diuretics are often necessary to reduce elevated filling pressures in patients with heart failure. However, they are known to activate neurohormonal mechanisms that may be harmful. -
Nonobstructive Coronary Plaque Detected by CT Predicts Mortality
Computed tomography (CT) imaging has progressed substantially in recent years, and we are now able to non-invasively image coronary artery disease in many patients. -
Does a Moderately Dilated Ascending Aorta Continue to Dilate After AVR for Severe AS?
In patients with severe valvular aortic stenosis (AS), ascending aortic dilatation is common, and is thought to be due to the alterations in flow caused by the stenotic valve. -
Importance of QRS Duration in Resynchronization Therapy
Cardiac resynchronization therapy (CRT) is now accepted as a disease-modifying therapy in patients with heart failure, left ventricular dysfunction, and intraventricular conduction defects. In this paper, Sipahi and colleagues review the data on the benefits of CRT in relationship to baseline QRS duration. -
Echo Assessment of Diastolic Function
The echocardiographic assessment of diastolic function of the left ventricle (LV) involves five measurements derived from two-dimensional imaging, pulsed Doppler, Color M-mode, and tissue Doppler. Not only is it complicated, but sometimes the measurements are discordant. -
