Arq Bras Cardiol. 2023 Sep 1;120(8):e20220840. doi: 10.36660/abc.20220840. eCollection 2023.


BACKGROUND: At the beginning of the COVID-19 pandemic, patients with myocardial infarction (MI) took longer to present to hospitals because of fear of contamination and health care access difficulties.

OBJECTIVES: To assess interventional cardiology procedures performed during the COVID-19 pandemic and its implications for MI approach.

METHODS: Prospective registry of 24 cardiac catheterization laboratories in Brazil, with adult patients undergoing interventional cardiology procedures between May 26 and November 30, 2020. The outcomes were cardiovascular (CV) and non-CV complications, death, and MI. Concomitant COVID-19 was confirmed using RT-PCR. Machine learning techniques were used with nonparametric Classification Trees models, and Simple Correspondence Analysis, with R statistical software package. Significance level adopted of 5%.

RESULTS: This study included 1282 patients, 435 of whom (33.9%) had MI as follows: ST-segment elevation MI (STEMI), 239 (54.9%); and non-ST-segment elevation MI (NSTEMI), 196 (45.1%). Of the 1282 patients, 29 had CV complications, 47 had non-CV complications, and 31 died. The diagnosis of COVID-19 was confirmed in 77 patients (6%), with 15.58% mortality and non-CV complications in 6.49%. Most patients had significant coronary artery disease (63%), and an intracoronary thrombus was more often found in the presence of STEMI (3.4%) and COVID-19 (4%). A door-to-table time longer than 12 hours in NSTEMI was associated with 30.8% of complications, 25% in COVID-19 patients.

CONCLUSIONS: All deaths were preceded by CV or non-CV complications. The presence of COVID-19 was associated with death and non-fatal complications of patients undergoing interventional cardiology procedures during the pandemic.
