This study aims to compare treatments and outcomes of mechanical complications of acute myocardial infarction (MI) during the Covid-19 and in the pre-Covid-19 era. Electronic databases have been searched for MI mechanical complications during the Covid-19 era and in the previous period from January 1998 to January 2020 (pre-Covid-19 era), until October 2021. To perform a quantitative analysis of non-comparative series, a meta-analysis of proportion has been conducted. Early mortality after surgical treatment was 15.0% while it was significantly higher after conservative treatment (62.4%) (P = 0.026). Early mortality after surgical treatment was seemingly higher in the pre-Covid-19 era but the difference did not reach statistical significance (15.0% vs 38.9%; P = 0.13). Mortality in patients treated conservatively, or turned down for surgery, was lower during the Covid-19 pandemic (62.4% vs 97.7%; P = 0.001). The crude mean prevalence of the use rate of conservative or surgical treatment across the studies during Covid-19 and in the pre-Covid-19 era was comparable. The current increased incidence of MI mechanical complications might be a consequence of delayed presentation or restricted access to hospital facilities. Despite the general negative impact of Covid-19 on cardiac surgery volumes and outcomes and the apparent increase of the incidence of MI complications, the outcomes of their surgical and clinical treatment seem not to have been affected during the pandemic.

Abstract

This study aims to compare treatments and outcomes of mechanical complications of acute myocardial infarction (MI) during the Covid-19 and in the pre-Covid-19 era. Electronic databases have been searched for MI mechanical complications during the Covid-19 era and in the previous period from January 1998 to January 2020 (pre-Covid-19 era), until October 2021. To perform a quantitative analysis of non-comparative series, a meta-analysis of proportion has been conducted. Early mortality after surgical treatment was 15.0% while it was significantly higher after conservative treatment (62.4%) (P = 0.026). Early mortality after surgical treatment was seemingly higher in the pre-Covid-19 era but the difference did not reach statistical significance (15.0% vs 38.9%; P = 0.13). Mortality in patients treated conservatively, or turned down for surgery, was lower during the Covid-19 pandemic (62.4% vs 97.7%; P = 0.001). The crude mean prevalence of the use rate of conservative or surgical treatment across the studies during Covid-19 and in the pre-Covid-19 era was comparable. The current increased incidence of MI mechanical complications might be a consequence of delayed presentation or restricted access to hospital facilities. Despite the general negative impact of Covid-19 on cardiac surgery volumes and outcomes and the apparent increase of the incidence of MI complications, the outcomes of their surgical and clinical treatment seem not to have been affected during the pandemic.
