Late, Post-COVID Cardiac Dysfunction Linked to Preexisting CAD

News

The study covered in this summary was published on ResearchSquare.com as a preprint and has not yet been peer reviewed.

Key Takeaways

  • Patients with recent COVID-19 infection and cardiovascular (CV) comorbidities can show significantly reduced echocardiographic left ventricular (LV) global longitudinal strain (GLS) values 3 months after the acute infection compared with patients with CV comorbidities and risk factors but no history of COVID-19.

  • A history of coronary artery disease (CAD), in particular, at admission with COVID-19 may predict long-term risk for myocardial dysfunction.

Why This Matters

Study Design

  • The cross-sectional study assessed LV GLS measurements by echocardiography 3 months after hospital admissions with COVID-19 in adults with CV comorbidities and risk factors from June to August 2021 at one center in Jakarta, Indonesia.

  • The population consisted of 100 case patients with preexisting cardiac comorbidities and risk factors recovered from a COVID-19 hospitalization (cases), 31 patients with cardiac comorbidities and no prior COVID-19 (control group 1), and 31 “healthy” subjects without cardiac comorbidities or a history of COVID-19 (control group 2).

  • Relationships between parameters at admission and later LV GLS values were assessed in multivariate analyses.

Key Results

  • The 162 participants averaged age 52 years and 62% were male.

  • Cases and control-group 1 participants were not significantly different with respect to prevalence of diabetes, hypertension, dyslipidemia, smoking, CAD, or obesity.

  • Means LV GLS values were significantly lower (P < .05) for patients in the case group (-16.17) compared with control groups 1 and 2 (-19.48 and -21.48, respectively).

  • Of parameters evaluated during the index hospitalization, only a presence of CAD was a significant multivariate predictor (P = .038) of decreased LV GLS in cases compared with the control groups.

  • COVID-19 had no apparent effect on right ventricular free-wall strain at 3 months regardless of CV comorbidities and risk factors.

Limitations

  • The study had a limited sample size and was from a single center, limiting generalizability.

  • Data on LV GLS prior to COVID-19 infection was not available.

  • Some data on relevant admission parameters, such as C-reactive protein, d-dimer, natriuretic peptides, and troponins were missing.

Disclosures

  • The study received no funding, grants, or other special support.

  • The authors declare no relevant financial or nonfinancial conflicts.
