Key Points

To explore the relationship between biomarkers and echocardiographic findings in Post-COVID-19 patients.
Cross-sectional design with 78 adults evaluated at a university hospital.
Participants divided into those with elevated (n=39) and normal NT-proBNP levels.
Echocardiographic parameters assessed alongside inflammatory markers.
Higher NT-proBNP levels correlate with increased myocardial stress.
GDF-15 is associated with inflammation in Post-COVID-19 patients.
Echocardiographic abnormalities present in participants with elevated NT-proBNP.

Structured PICO

Are elevated NT-proBNP levels associated with increased inflammatory cytokines and subclinical echocardiographic dysfunction in patients with Post-COVID-19 Condition?

Population

78 adults in the post-COVID-19 period (prior PCR-confirmed SARS-CoV-2), median age 61, 33.3% male, from a tertiary care university hospital in Brazil. High prevalence of hypertension (70.5%), dyslipidemia (53.8%), and diabetes (35.9%).

Intervention

Elevated NT-proBNP levels at baseline (n=39)

Comparator

Normal NT-proBNP levels (n=39), matched 1:1 for sex, age, diabetes, and hypertension

Outcome

Associations between NT-proBNP, GDF-15, inflammatory cytokines, and echocardiographic parameters (PALS and RV-GLS)surrogate

Elevated NT-proBNP and GDF-15 levels identify subclinical myocardial dysfunction and local inflammation in post-COVID-19 patients, suggesting a chronic inflammatory mechanism for cardiac damage.

Abstract

Background Some patients experience subclinical cardiovascular dysfunction after COVID-19, possibly driven by persistent inflammatory mechanisms that remain incompletely understood. NT-proBNP and GDF-15 have been proposed as biomarkers of myocardial stress and inflammation in this context. Objectives To investigate associations between NT-proBNP, GDF-15, inflammatory cytokines, and echocardiographic parameters in patients with Post-COVID-19 Condition (PCC). Methods This cross-sectional study included 78 adults followed in a university hospital cohort. Participants were stratified into elevated NT-proBNP (n = 39) and normal NT-proBNP (n ...
