Abstract
Background: Area strain evaluates the longitudinal and circumferential deformation simultaneously. There are not estudies that support its benefit in predicting functional recovering in myocardial infarction.
Objective: The aim was establish the prognostic value of the area strain measured within the first 7 days after succesful angioplasty to predicting functional recovering.
Materail and methods: A prospective cohort study was performed during 3-month follow-up. Patients with myocardial infarction treated with succesful angioplasty were enrolled. The area strain was perfomed within the first 7 days. Functional recovering was defined as an improvement of the ejection fraction ≥ 10% at 3-months follow-up.
Results: A total of 52 patients were enrolled. An area strain of ≤ -24.2 % appeared in the 45.5% of the patients with functional recovering, RR 16.25 (IC 95%: 2.55-103, p = 0.003). In the multivariate analyses the area strain of ≤ -24.2 % was the only variable with statistical significance with an OR of 13.15 (IC 95%: 1.83-94, p = 0.010) when was adjusted to hypertension, OR of 12.7 (IC 95%: 1.88-85.9, p = 0.009) adjusted to reperfusion time of ≤ 120 minutes and the OR was of 11.87 (IC 95%: 1.66-84.5, p = 0.013) adjusted to smoking.
Conclusions: An area strain of ≤ - 24.2% is a prognostic factor of improvement of ejection fraction of ≥ 10% at 3-months follow-up in patients with myocardial infarction and succesful angioplasty.
