GUTIERREZ-NOGUERA, María P. et al. Prevalence of myocardial infarction with non-obstructive atherosclerotic coronary artery disease (MINOCA). Rev. Colomb. Cardiol. [online]. 2023, vol.30, n.1, pp.10-14. Epub 09-Fev-2023. ISSN 0120-5633. https://doi.org/10.24875/rccar.21000122.
Objective:
To determine the prevalence and cardiovascular risk factors in patients with acute myocardial infarction with non-obstructive coronary lesions in coronary arteriography in a health institution with intermediate and specialized care in the city of Valledupar (Cesar), Colombia.
Materials and methods:
This was a descriptive, cross-sectional, single-center study. All patients included were over 18 years of age. They presented an acute coronary syndrome and were treated in a health center in Valledupar, Colombia. Coronary arteriography was completed, and patients met the criteria for MINOCA according to the fourth universal definition of myocardial infarction. The prevalence of MINOCA and description by sex, age, cardiovascular risk factors, and type of ACS presentation were calculated. The study was carried out between January 2016 and December 2019.
Results:
Of the 3.022 patients diagnosed with acute myocardial infarction, 215 did not have non-obstructive coronary lesions, with a prevalence of 7.11% (CI 95%: 6.20-8.03%). Most subjects were women (53.02 %), and the mean age was 56.6 years. 75.8% of participants had at least one cardiovascular risk factor, predominantly arterial hypertension (67.4%). Most patients had non-ST-segment elevation acute coronary syndrome (93.5%).
Conclusion:
The prevalence of MINOCA in our institution is within the range described in the medical literature. The clinical characteristics found were similar to those reported in the literature. Further studies need to be conducted to determine the cause in this type of patient.
