Key result
The study aimed to compare the predictive accuracy of intracoronary pressure-wire and transthoracic Doppler echocardiography-based parameters for estimating long-term LV infarct size and function.
Why the study?
Does deceleration time of diastolic coronary flow measured by transthoracic echocardiography accurately predict long-term left ventricular infarct size and function compared to intracoronary pressure-wire in patients with reperfused AMI?
Observational
Does deceleration time of diastolic coronary flow measured by transthoracic echocardiography accurately predict long-term left ventricular infarct size and function compared to intracoronary pressure-wire in patients with reperfused AMI?
The study evaluates whether non-invasive transthoracic Doppler echocardiography can accurately predict long-term LV infarct size and function compared to invasive intracoronary pressure-wire assessment after AMI.
TTE-based coronary flow parameters may aid non-invasive post-AMI assessment; leaves open whether they match pressure-wire accuracy for LV outcomes.
Assessment of microvascular function after reperfused acute myocardial infarction (AMI) provides important insights for myocardial reperfusion and facilitates prediction of long-term left ventricular (LV) function and clinical outcome. In this study, we examined microvascular integrity 48 h after successful primary percutaneous coronary intervention (PCI) and compared predictive accuracy of the intracoronary pressure-wire-and transthoracic Doppler echocardiography-based parameters in the estimation of long-term LV infarct size and function.

Okçular et al. (2010) conducted an observational in Reperfused acute myocardial infarction (AMI). Transthoracic Doppler echocardiography-based parameters (deceleration time of diastolic coronary flow) vs. Intracoronary pressure-wire-based parameters was evaluated on Long-term left ventricular (LV) infarct size and function. The study aimed to compare the predictive accuracy of intracoronary pressure-wire and transthoracic Doppler echocardiography-based parameters for estimating long-term LV infarct size and function.
