Greater decline of acute stroke admissions compared with acute coronary syndromes during COVID-19 outbreak in Greece: Cerebro/cardiovascular implications amidst a second wave surge.

BACKGROUND AND PURPOSE

A remarkable decline in admissions for acute stroke and acute coronary syndrome (ACS) has been reported in countries severely hit by the COVID-19 pandemic. However, limited data are available from countries with less COVID-19 burden focusing on concurrent stroke and ACS hospitalisation rates from the same population.

METHODS

The study was conducted in three geographically and demographically representative COVID-19 referral university hospitals in Greece. We recorded the rate of stroke and ACS hospital admissions during a 6-week period of the COVID-19 outbreak in 2020 and compared them with the rates of the corresponding period in 2019.

RESULTS

We found a greater relative reduction of stroke admissions (51% [35 vs. 71]; incidence rate ratio [IRR]: 0.49, p = 0.001) compared with ACS admissions (27% [123 vs. 168]; IRR: 0.73, p = 0.009) during the COVID-19 outbreak (p = 0.097). Fewer older (>65 years) patients (stroke: 34.3% vs. 45.1%, odds ratio [OR]: 0.64, p = 0.291; ACS: 39.8% vs. 54.2%, OR: 0.56, p = 0.016) were admitted during the COVID-19 compared with the control period.

CONCLUSIONS

Hospitalisation rates both for stroke and ACS were reduced during the COVID-19 outbreak in a country with strict social distancing measures, low COVID-19 incidence and low population mortality. Lack of triggers for stroke and ACS during social distancing/quarantining may explain these observations. However, medical care avoidance attitudes among cerebro/cardiovascular patients should be dissipated amidst the rising second COVID-19 wave.
