Background: To evaluate the prognostic value of tissue Doppler imaging (TDI)-derived parameters (E/E' ratio and Tei index) in heart failure (HF) patients who underwent cardiac resynchronization therapy (CRT). Methods and Results: The study comprised 74 consecutive HF patients (mean age 60 +/- 11 years) who underwent CRT. Echocardiography including ...
The rat infarct model is widely used to study left ventricular (LV) remodeling, a main cause of heart failure characterized by progressive LV dilatation. Using pinhole collimators and advances in data processing, gated SPECT was recently adapted to image the rat heart. The aim of this study was to assess this new imaging technique for predicting an...
OBJECTIVES This study was designed to evaluate the value of 64-slice computed tomography (CT) to visualize the cardiac veins and evaluate the relation between variations in venous anatomy and history of infarction. BACKGROUND Cardiac resynchronization therapy (CRT) is an attractive treatment for selected heart failure patients. Knowledge of venous ...
There is evidence that the classical complement pathway may be activated via a “C1-tickover” mechanism, analogous to the C3-tickover of the alternative pathway. We have quantitated and characterized this pathway of complement activation. Analysis of freshly collected mouse and human plasma revealed that spontaneous C3 activation rapidly occurred wi...
The fundamental aim of the International Studies of Infarct Survival (ISIS) collaborative group is to assess reliably the balance of any benefits and risks for widely practicable treatments that might produce moderate but worthwhile mortality reductions in patients with suspected acute myocardial infarction. Substantial numbers of lives might be sa...
