ABSTRACT

BACKGROUND:

Covid-19 is multi-system viral infection caused by SARS-CoV-2 virus. Apart from having acute severe respiratory illness causing high mortality, the disease also has a variety of cardiovascular manifestations contributing to morbidity as well as mortality. Cardiac dysfunction and myocarditis are well established complications of Covid-19 as evident in multiple studies after the Covid-19 pandemic. However it is not sufficiently studied in Indian patients either by Echocardiography or by any other imaging modalities like cardiac magnetic resonance imaging (MRI).

METHODOLOGY:

In this study, we analysed the severity of Left ventricular(LV) dysfunction in Covid-19 survivors. A total of 100 consecutive patients of Covid-19 after one month of discharge who had no underlying cardiovascular diseases underwent echocardiography and global longitudinal strain (GLS) imaging. This study cohort included patients with mild 42 (42%),moderate 46(46%) and severe 12(12%) Covid-19 disease as defined by computerised tomography (CT) severity score.

RESULT:

We observed that total 36(36%) patients had reduced ejection fraction(EF) which included 11 patients having EF <40% and remaining 25(25%) having EF 40-50% (p<0.002). Also 22 (22%) patients had abnormal global longitudinal strain (GLS) values with normal ejection fraction which is suggestive of subclinical myocarditis. We observed LV dysfunction in 7(19.5%) patients who had severe Covid-19 while mild to moderate LV dysfunction observed in 29(80.5%) non critical patients.

CONCLUSION:

In conclusion our study demonstrates that myocardial dysfunction is common in covid-19 regardless of disease severity. 2D-echocardiography with GLS is likely to detect early LV dysfunction among these patients.
