Extended Data Table 2 Baseline characteristics of subgroups stratified by symptom status at baseline and at follow-up

From: Long-term cardiac pathology in individuals with mild initial COVID-19 illness

  1. Baseline characteristics of subgroups stratified for the symptom status at baseline and at follow-up. Cardiac symptoms were present in 198 (57%) patients at follow-up; symptoms persisted in a total of 182 (53%) patients; 16 (5%) previously asymptomatic patients developed new symptoms, 78 (23%) originally asymptomatic patients remained asymptomatic, and 70 (20%) patients became asymptomatic. Sym – symptomatic symptom status, Asym – asymptomatic symptom status; Subgroup: at baseline/at follow-up. BMI – body mass index, BP – blood pressure, CRP – C-reactive protein; hs-TropT – high-sensitive troponin T, NT pro BNP – N terminal pro brain natriuretic peptide, LV- EDVi – Left ventricular end-diastolic volume, indexed to body surface area, LVEF – LV ejection fraction, GLS – global longitudinal strain; RVEF – right ventricular ejection fraction, LGE – late gadolinium enhancement, ms – millisecond, ml – milliliter, m – meter, bpm – beats per minute, mmHg, millimeter Mercury, pg – picogram. Ischemic and non-ischemic scar may occur in the same patient. The categorical classifications of LVEF, RVEF and LV-EDVi are based on the UK Biobank study30. Posthoc testing was performed at the level of p≤0.05 in the global analysis. Significant posthoc tests using Bonferroni correction are denoted as # vs. Sym/Sym, § Asym vs. Sym.
