Contrast-enhanced cardiovascular magnetic resonance in the hyperacute phase of ST-elevation myocardial infarction
Optional Fields

Cardiovascular magnetic resonance (CMR) very early after primary percutaneous coronary intervention (PPCI) may lead to instability or early stent complications. However, CMR in the hyperacute phase of STEMI may improve risk stratification. We investigated feasibility and safety of CMR in the hyperacute phase of STEMI immediately after PPCI. One hundred and twenty eight consecutive patients immediately after PPCI for STEMI. Sixty four underwent CMR < 12 h after PPCI versus 64 matched controls. Outcomes were followed over 6 months. CMR in hyperacute STEMI was not associated with in-hospital death, infarct expansion, or urgent revascularization (P=NS). CMR (32 ml gadolinium contrast) immediately after PPCI (180 ml iodine contrast) did not increase nephropathy. CMR did not increase major adverse cardiac events (5 vs. 8\%, P=0.16) or recurrence of angina (6 vs. 8\%, P=0.73) at 6 months. CMR immediately after PPCI is feasible and safe, allowing very early risk stratification in STEMI.
