Abstract | Abstract
Aims
Coronary artery ectasia (CAE) is not a rare finding in coronary angiography with a prevalence ranging from 1% to 20% according to clinical setting. The aim of this study was to analyse the angiographic differences of coronary ectasia based on admitting diagnosis.
Methods and results
A cohort study was conducted including patients with angiographic evidence of CAE between January 2016 and December 2020. The study population was divided into two groups according to the clinical presentation: stable coronary artery disease (SCAD) and acute coronary syndrome (ACS). Markis classification, basal thrombolysis in myocardial infarction (TIMI) flow of each coronary artery, associated coronary artery obstruction (CAO), and respective Gensini score were reported. A total of 144 patients were included in this study. No difference were found concerning age or the traditional cardiovascular risk factors. Compared to general population, higher rates of myocardial infarction with non-obstructive coronary arteries (MINOCA) and ischaemia with non-obstructive coronary arteries (INOCA) (31% of the entire ACS cohort and 42% the SCAD group, respectively) were observed. Furthermore, irrespective of lower Gensini score values, MINOCA patients showed significantly more widespread CAE and a more severe impairment of coronary flow compared to SCAD and obstructive ACS patients.
Conclusions
CAE patients show a surprisingly high rate of acute coronary syndromes with non-obstructive coronary arteries. The extent of the ectatic involvement and its consequences on coronary blood flow could be the base of the higher rate of ACS events observed in this population, recognizing mechanisms other than plaque rupture. |
