Impact of the COVID-19 lockdown on ischaemic heart disease: before-and-after observational study

Background: The onset of the COVID-19 pandemic had a huge impact on our
society, even the healthcare system had to adapt to the new circumstances. The
online access to healthcare centres became easier, but the barriers between
physicians and patients were multiplied. Many interventions and consultations
were delayed for many months with the purpose of reducing the contagion.
Nevertheless, some pathologies cannot be postponed, they must be diagnosed
and treated immediately. One of them is heart ischaemic disease, which is the
main cause of mortality worldwide. Different studies around the globe have
already shown a change in its tendencies: decrease in hospital admissions,
increase in mortality, and treatment delay, among others.
It is known that we will keep having outbreaks until a treatment or a vaccine are
found, so we might end up in a similar situation very soon. Knowing exactly which
procedures were altered during the National quarantine in our environment is the
first step to prevent them from malfunctioning again in the next lockdown.
Objectives: The main objective is to determine whether there is an increase in
time-to-reperfusion of STEMI during and after the COVID-19 lockdown compared
to the same periods in the previous year in Girona.
The secondary objective is to determine whether there is a decrease in the
accumulated incidence of STEMI during and after the COVID-19 lockdown
compared to the same periods in the previous year in Girona.
Methodology: It is a before-and-after observational study using a population-
based AMI registry, the registre Codi IAM. We will compare time-to-reperfusion,
incidence and mortality in Girona between the COVID-19 lockdown, the following
period until the next outbreak, and the same periods the year before by the
corresponding analysis of variance, Poisson regression and Cox Proportional-
Hazard. The 3 analysis will be stratified by covariates.
Participants: All the STEMI occurred in Girona and treated in the Hospital Dr
Josep Trueta during the 4 periods
