Impact of acute total occlusion of the culprit artery on outcome in NSTEMI based on the results of a large national registry
BMC Cardiovascular Disorders Jun 17, 2021
Terlecki M, Wojciechowska W, Dudek D, et al. - Researchers used the Polish National Registry to assess the clinical as well as angiographic phenotype and result of non-ST-segment elevation myocardial infarction (NSTEMI) patients with total occlusion (TO) (NSTEMI TO ) vs NSTEMI patients without TO (NSTEMI NTO ) and those with ST-segment elevation and TO (STEMI TO ). They analyzed relevant data of patients with acute myocardial infarction who had percutaneous coronary intervention (PCI) between 2014 and 2017. In terms of mean age, Killip class IV on admission, cardiac arrest before admission and death during PCI, intermediate outcomes were seen in the NSTEMI TO group vs the NSTEMI NTO and STEMI TO groups. According to findings, an obvious difference existed between the NSTEMI TO group and NSTEMI NTO group. NSTEMI TO seemed to be an intermediate condition between NSTEMI NTO and STEMI TO , although the longest time delay to as well as the worst outcome of PCI were found in NSTEMI TO patients, which can be explained by the location of the culprit lesion in the left circumflex artery.
