%X background: intravascular ultrasound (ivus) provides a sensitive and reproducible measurement of coronary artery dimensions, atherosclerotic plaque, and arterial lumen. advances in ivus technology now allow the characterization of the composition and morphology of atherosclerotic plaques. although previous studies have reported data using ivus radiofrequency analysis, the use of a new modality (imap£¿, boston scientific, santa clara, usa) of atherosclerotic plaque characterization is very little known. our objective is to analyze the morphological, phenotypic and tissue characteristics of "culprit" and "non-culprit" atherosclerotic plaques determined by angiography in patients undergoing coronary angiography due to acute myocardial infarction (ami). methods: prospective, cross-sectional, single center study (hospital s£¿o paulo - escola paulista de medicina - universidade federal de s£¿o paulo/unifesp, s£¿o paulo, sp, brazil). fifty patients will be selected for ultrasound analysis according to the following inclusion criteria: age < 75 years, non-st-segment elevation ami or recent st-segment elevation ami, with or without previous fribrinolytic agents. conclusions: the present study is aimed at obtaining morphological, phenotypic and tissue characteristics of the atherosclerotic plate using an imaging modality not extensively evaluated in patients with ami.
