Population
204 patients with a single myocardial infarct, autopsied at The Johns Hopkins Hospital
Design
Cross-sectional
Key result
Larger, more transmural infarcts and those in the left anterior descending artery distribution were associated with significantly greater infarct expansion (p<0.001).

Infarct expansion is associated with larger, transmural infarcts in the LAD distribution, but is less marked in hearts with pre-existing left ventricular hypertrophy.

Infarct expansion is associated with larger, transmural infarcts in the LAD distribution, but is less marked in hearts with pre-existing left ventricular hypertrophy.
Pirolo et al. (1986) conducted an observational in single myocardial infarct (n=204). Infarct characteristics (size, transmurality, location) was evaluated on Degree of infarct expansion (p=<0.001). Larger, more transmural infarcts and those in the left anterior descending artery distribution were associated with significantly greater infarct expansion (p<0.001).
