Key result
Acute RV strain in hospitalized COVID-19 patients is linked to a ~50% mortality rate.
Why the study?
The overall prevalence of right ventricular strain secondary to COVID-19 has not been well established.
Observational
Yes
Acute right ventricular strain is rare (~1.5%) in hospitalized COVID-19 patients but is associated with a high mortality rate of 50%.
Acute RV strain flags high-mortality COVID-19 subgroup; observational data leave open whether targeted interventions improve outcomes.
Coronavirus disease 2019 or COVID-19 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-COV-2), a virus that has impacted nations and caused a global pandemic. Although COVID-19 is known to initially manifest as a pulmonary disease, we now understand it affects many major organ systems in the body, including the heart. Case reports have been published showing evidence of right ventricular (RV) strain as a result of contracting the COVID-19. However, the overall prevalence of RV strain secondary to the virus has not been well established. In this multicenter, observational analysis, we studied the prevalence of RV strain in hospitalized patients with COVID-19. We found the prevalence of RV strain to be small, ~1.5%. The average length of stay in patients with RV strain was 7 days compared to 8.63 days in non-RV strain patients. Those with RV strain were witness to have a 50% mortality rate.

Eftekharzadeh et al. (2022) conducted an observational in COVID-19. Right ventricular strain vs. Non-right ventricular strain was evaluated on Mortality rate. Acute right ventricular strain was observed in 1.5% of hospitalized COVID-19 patients, who experienced a 50% mortality rate and an average length of stay of 7 days versus 8.63 days without strain.
