Implication

Postextrasystolic potentiation may estimate final LV function after acute MI; hypothesis-generating and requires prospective validation before clinical use.

Structured PICO

Does postextrasystolic potentiation during acute transmural infarction predict final left ventricular function at 1 month?

Population

12 subjects without clinical or hemodynamic heart failure, admitted for a first untreated anterior transmural myocardial infarction, evaluated within the first 24 hours after the onset of symptoms.

Intervention

Pulmonary angiography with right ventricular extrastimulus delivered every fourth beat at 50% of the RR interval to analyze postextrasystolic left ventricular frames.

Comparator

Basal cycle of the initial angiogram.

Outcome

Correlation of initial ejection fraction (EF) and percentage of hypokinetic (%HK) or akinetic (%AK) areas with final angiogram at 1 month.surrogate

Postextrasystolic potentiation during acute transmural infarction allows accurate estimation of final left ventricular function and regional wall motion abnormalities at 1 month.
