BACKHOUSE, Christian et al. Decrease in the activity of interventional cardiology in Chile: a report from the “Stent-Save a Life! LATAM working group”. Rev Chil Cardiol [online]. 2021, vol.40, n.2, pp.121-126. ISSN 0718-8560.


The Stent-Save a Life! (SSL) LATAM working group designed a survey to demonstrate the reduction in the activity of cardiac catheterization laboratories in Latin America during the COVID-19 pandemic. Considering the risk of a new confinement in Chile, we decided to assess the impact of the first wave of contagions on our activity.


To discuss the repercussion of the COVID-19 pandemic on the activity of interventional cardiology in Chile.


The SSL group conducted a telematic survey in all Latin American countries. Coronary angiography, coronary interventions (PCI) and structural interventions were registered, comparing two periods of two weeks duration each: before and during COVID-19 confinement. Results obtained in Chile are analyzed.


Thirteen centers in Chile answered the survey. There was an overall decrease of 65.1% in the number of procedures between the pre and the post COVID-19 periods. Coronary angiographies decreased 67%, PCI 59.4% and therapeutical structural procedures 92%. The reduction in acute coronary syndrome with ST segment elevation (STEMI) was 40,8% between periods.


In Chile, a significant reduction in healthcare activity related to interventional cardiology and a significant decrease in the number of patients treated with STEMI was observed during the COVID-19 pandemic. The results are similar to those reported by Latin American, European and North American countries.
