Left ventricular dyssynchrony and abnormalities in wall motion, assessed by gated-SPECT as ischemic auxiliary markers.

Introduction: Left ventricular dyssynchrony (LVD) quantified by gated myocardial perfusion studies (MPS), through phase analysis (PA), has shown controversial results in myocardial stunning.

Objectives: Assessment of LVD and regional wall motion abnormalities (RWMA) in normal and ischemic patients.

Methods: A cohort of 172 patients were studied.

[Use of Gated-SPECT with with 99mTC-MIBI in the evaluation of the prognostic significance of ventricular arrhythmias during a stress test].

Unlabelled: The presence of ventricular complex cardiac arrhythmias in coronary patients, both at rest or during physical exercise, is considered a risk factor for future coronary events or sudden death during long time follow up. The meaning of ventricular complex arrhythmias (VCA) in patients with normal ventricular function and without myocardium ischemia has still not been explained. This study aimed to evaluate if patients with normal ventricular function and no evidence of cardiac ischemia (determined by means of Gated SPECT) who developed VCA during stress test show an increase in cardiac events on later monitoring.
