Overview

Echocardiography may support LVEF assessment in ischemic cardiomyopathy; leaves open volume accuracy versus gated SPECT.

Structured PICO

Does two-dimensional echocardiography accurately measure LVEF, EDV, and ESV compared to gated myocardial SPECT in patients with ischemic cardiomyopathy?

P
Population
70 patients with left ventricular systolic dysfunction (ischemic cardiomyopathy)
I
Intervention
Two-dimensional echocardiography (using Simpson's method in triplane, biplane, and monoplane apical four chamber projections)
C
Comparator
Gated myocardial SPECT
O
Outcome
Accuracy/agreement in the measurement of left ventricular ejection fraction (LVEF), end-diastolic volume (EDV), and end-systolic volume (ESV)surrogate

Echocardiography is a valid tool for LVEF assessment but systematically underestimates LV volumes compared with gated SPECT in patients with LV systolic dysfunction.
