Prognostic implication of Doppler echocardiographic derived coronary flow reserve in patients with left bundle branch block.
AIMS Myocardial ischaemia during pharmacological stress echocardiography is a strong prognostic predictor in patients with a left bundle branch block (LBBB). However, the additive value of Doppler-derived coronary flow reserve (CFR) during pharmacological stress testing remains to be investigated in this subset of patients. METHODS AND RESULTS The study group consisted of 324 LBBB patients (1...
متن کاملCoronary artery occlusions diagnosed by transthoracic Doppler
BACKGROUND Our aim was to assess whether anterograde flow velocities in septal perforating branches could identify an occluded contralateral coronary artery, and to assess the feasibility and accuracy of diagnosing occlusions in the three main coronary arteries by the combined use of several noninvasive parameters indicating collateral flow. METHODS A total of 108 patients scheduled for coron...
متن کاملis there any difference in cardiogoniometry parameters of ischemic and nonischemic cardiomyopathy in patients with left bundle branch block?
background differentiating ischemic from nonischemic cardiomyopathy is important both prognostically and therapeutically, although it may be difficult clinically. objectives we aimed to determine the diagnostic power of cardiogoniometry (cgm) in the differentiation of the ischemic from the nonischemic etiology of left bundle branch block (lbbb). patients and methods we studied 37 patients with ...
متن کاملLeft Bundle Branch Block
Coronary angiography, cine left ventriculography, and the cardiovascular hemodynamics of 24 patients with left bundle branch block were studied. Seven patients were found to have significant coronary artery disease, always severe. Five had cardiomyopathy and seven had valvular disease. Only those with coronary artery disease or cardiomyopathy had abnormal left ventricular contraction patterns. ...
متن کاملLeft bundle branch block.
A RECENT STUDY of the prognosis of patients with left bundle branch block (L.B.B.B.) suggested that life expectancy was extremely short (Smith and Hayes 1965). While in general L.B.B.B. has a sinister reputation, we have been struck by a few individuals who have survived many years with L.B.B.B., and we thought an analysis of some of the material available at the Royal Victoria Hospital, Belfas...
