Characterization of nontransmural myocardial infarction by positron-emission tomography.

abstract：BACKGROUND:Prior small to modest-sized studies suggest a benefit of intravascular ultrasound (IVUS) guidance in noncomplex lesions. Whether IVUS guidance is associated with improved clinical outcomes after drug-eluting stent (DES) implantation in an unrestricted patient population is unknown. METHODS AND RESULTS:Asses...
