Introduction
Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA) means a non-negligible proportion of patients (pts) admitted for MI. However, there are still unsolved questions about this entity. The aim of our study is to analyse the differences between the MINOCA group compared with pts admitted for MI with obstructive coronary disease.
Method
Analytical and observational study developed in a Universitary Hospital, which covers 220.000 individuals. From january-2016 until december-2018 we reviewed all the pts that were admitted for MI who underwent coronariography. MINOCA pts (defined according 2016 ESC Working Group position paper) compared with MI pts with obstructive lesions.
Results
One hundred and nine from 521 pts admitted for MI in whom a coronariography was performed fulfilled the 2016 ESC criteria of MINOCA (20%). Clinical presentation showed no difference in Killip-Kimball classification (K-K > I was 6.1% in MI with obstructive lesions vs 6.5% in MINOCA pts, p 0.897). Chest pain (Angina) was more frequent in MI with obstructive lesions (82.8% vs 73.4%, p 0.027) and they also had more ST changes (ST elevation 41% vs 24%, p 0.001; ST descent 17% vs 8.3%, p 0.026). MINOCA pts had lower levels of troponine (troponine elevation less than 10 times the 99th percentile: 10.4% vs 26.6%, p |
