Association of adverse cardiovascular outcomes with weighted morphologic variability following non-ST-elevation acute coronary syndromes
Year: 2010
Type: dissertation
Abstract: Patients who have had an acute coronary syndrome(ACS) are at a relatively high risk of having subsequent adverse
cardiac events. Several electrocardiographic (ECG) measures such as
heart rate variability, heart rate turbulence, deceleration
capacity, T-wave altemans, and morphologic variability have been
used to identify patients at an increased risk of recurrent
myocardial infarctions and cardiovascular death. In this work, we
develop a new ECG-based measure for patient risk stratification
called weighted morphologic variability. This measure is based on
assessment of beat-to-beat changes in the morphology of consecutive
beats. Weighted morphologic variability identifies patients who are
at more than four-fold risk for cardiovascular death, which is an
improvement in ECG-based risk stratification. The body of this work
suggests that prognosticating patients based on
electrocardiographic measures is an effective way of identifying
those at risk of adverse cardiovascular outcomes.
