Abstract

Purpose: Impaired left and right ventricular (LV/RV) function during acute SARS-CoV-2 infection has been predominantly reported in hospitalized patients, but long-term cardiac sequelae in large, well-characterized cohorts remain inconclusive. This study evaluated cardiac structure and function in individuals with post-Coronavirus disease (COVID) syndrome (PCS) compared to recovered controls (CON), focusing on associations with cardiopulmonary symptoms and rapid physical exhaustion (RPE).

Methods: This multicenter, population-based study included 1154 participants (679 PCS, 475 age- and sex matched CON; mean age 49 ± 12 years; 760 women) 1.5 years post-infection. Transthoracic echocardiography assessed LV global longitudinal strain (GLS), RV GLS and RV free wall strain (FWS), and other measures. Cardiopulmonary exercise testing (CPET) measured maximum respiratory oxygen uptake (VO₂max) as a marker of cardiopulmonary fitness.

Results: PCS participants exhibited significantly lower LV GLS (-20.25% [-21.28 - -19.22] vs. -20.73% [-21.74 - -19.72], p = 0.003), reduced diastolic function (E/A 1.16 [1.04-1.27] vs. 1.21 [1.1-1.32], p = 0.022) and decreased TAPSE (24.45 mm [22.14-26.77] vs. 25.05 mm [22.78-27.32], p = 0.022) compared to CON, even after adjusting for confounders. RV strain values were similar between groups. LV GLS correlated inversely with VO₂max (p = 0.004) and positively with RPE (p = 0.050), though no associations were observed with other cardiopulmonary symptoms.

Conclusions: This study demonstrates subtle yet consistent reductions in LV function, specifically LV GLS and diastolic function, and exercise capacity in PCS compared to CON. While these changes are within reference ranges, their potential impact on clinical outcomes warrants further investigation. These findings highlight the need for cardiac assessments and long-term follow-up in symptomatic PCS patients.

期刊介绍： Infection is a journal dedicated to serving as a global forum for the presentation and discussion of clinically relevant information on infectious diseases. Its primary goal is to engage readers and contributors from various regions around the world in the exchange of knowledge about the etiology, pathogenesis, diagnosis, and treatment of infectious diseases, both in outpatient and inpatient settings. The journal covers a wide range of topics, including: Etiology: The study of the causes of infectious diseases. Pathogenesis: The process by which an infectious agent causes disease. Diagnosis: The methods and techniques used to identify infectious diseases. Treatment: The medical interventions and strategies employed to treat infectious diseases. Public Health: Issues of local, regional, or international significance related to infectious diseases, including prevention, control, and management strategies. Hospital Epidemiology: The study of the spread of infectious diseases within healthcare settings and the measures to prevent nosocomial infections. In addition to these, Infection also includes a specialized "Images" section, which focuses on high-quality visual content, such as images, photographs, and microscopic slides, accompanied by brief abstracts. This section is designed to highlight the clinical and diagnostic value of visual aids in the field of infectious diseases, as many conditions present with characteristic clinical signs that can be diagnosed through inspection, and imaging and microscopy are crucial for accurate diagnosis. The journal's comprehensive approach ensures that it remains a valuable resource for healthcare professionals and researchers in the field of infectious diseases.
