1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

abstractCOVID-19 has been linked to persistent cardiovascular sequelae, yet the trajectory of structural and functional cardiac changes beyond the acute phase remains unclear. This systematic review synthesizes longitudinal evidence on post-COVID cardiac remodeling assessed by imaging and biomarkers. Following PRISMA guidelines, we searched PubMed and Cochrane Library (January 2020-April 2025) for peer-reviewed studies enrolling adults (≥18 years) with polymerase chain reaction (PCR)/antigen-confirmed SARS-CoV-2 infection and reporting cardiac outcomes ≥ 12 weeks post-infection. Eligible outcomes included imaging-based abnormalities (cardiac magnetic resonance [CMR]: T1/T2 mapping, late gadolinium enhancement [LGE]; echocardiography: left ventricular ejection fraction [LVEF], LV/RV strain). Longitudinal trends of biomarkers (troponin, NT-proBNP, C-reactive protein [CRP]) were also studied. Risk of bias was assessed using joanna briggs institute (JBI) tools; synthesis followed synthesis without metaanalysis (SWiM) principles. Fifteen studies (n ≈ 166,000; 14 cohorts, 1 case report) were included. Across CMR cohorts, global systolic function was largely preserved, but tissue abnormalities were frequent early and improved over time: edema indices normalized by ~ 12 months, while LGE prevalence declined (e.g. 50%→19% in paired scans). However, residual non-ischemic scars and elevated T1/T2 persisted in symptomatic subgroups. Echocardiography showed normal LVEF, but subtle left ventricular global longitudinal strain (LV-GLS) impairment versus controls (e.g. -18.5% vs - 19.3%). Biomarker trends were heterogeneous: natriuretic peptide positivity persisted in patients with prior cardiovascular disease (CVD), while troponin and CRP generally normalized. Large population-based cohorts demonstrated sustained 12-month risk for heart failure, myocarditis, and major cardiovascular events, graded by acute severity. Most patients recover gross systolic function, yet subclinical myocardial changes and elevated population-level cardiovascular risk persist up to 1 year. These findings support risk-stratified follow-up, judicious use of advanced imaging, and preventive cardiology strategies.
