Comparison
Elective percutaneous transluminal coronary… vs Baseline left ventricular segmental function

Cohort, Echocardiograms were reviewed in a blind fashion
Follow-up
3.1 +/- 2 days after PTCA

Implication
May support elective PTCA for chronic segmental dysfunction; hypothesis-generating and requires randomized confirmation.
Structured PICO
Does elective PTCA improve resting left ventricular segmental function in patients with chronic segmental myocardial dysfunction?
P
Population
40 patients undergoing elective percutaneous transluminal coronary angioplasty (PTCA), including 20 with abnormal regional wall motion before the procedure (13 with prior MI, 7 without).
I
Intervention
Elective percutaneous transluminal coronary angioplasty (PTCA)
C
Comparator
Baseline (pre-PTCA) left ventricular segmental function
O
Outcome
Resting left ventricular segmental function (regional wall motion score) assessed by serial two-dimensional echocardiogramssurrogate
Elective PTCA significantly improves resting left ventricular regional wall motion in patients with chronic segmental myocardial dysfunction, regardless of prior myocardial infarction status.
