Post-COVID Cardiac Symptom Burden Score (Composite): Explanation and Clinical Context This calculator provides a pragmatic composite symptom burden score focused on cardiovascular manifestations reported after SARS-CoV-2 infection. It aggregates nine domains commonly described in post-acute COVID-19 cohorts: dyspnea (rest and exertion), chest pain/pressure, palpitations, dizziness/presyncope, orthostatic intolerance, exercise intolerance/post-exertional symptom exacerbation, lower-extremity edema, and fatigue. Each domain is rated 0–10 and summed (0–90).
The output also includes two publication-anchored subscores: a C19-YRS-inspired cardiac trio (breathlessness on exertion, chest pain, palpitations) and a COMPASS-31-inspired autonomic proxy (palpitations, dizziness/presyncope, orthostatic intolerance). Severity bands are heuristic and intended to support longitudinal tracking and triage conversations; they are not validated prognostic strata. Key red flags (acute/unstable chest pain, exertional syncope, rapidly progressive dyspnea/orthopnea) prompt urgent evaluation.
This structure reflects the literature showing that long-COVID frequently features breathlessness, fatigue, palpitations, dizziness, and exercise intolerance; that autonomic symptoms are common; and that there is an elevated population-level risk of incident cardiovascular disease following COVID-19, even after the acute phase.

Important: there is currently no universally accepted, validated, cardiac-specific composite symptom score for post-COVID care. This tool operationalizes domains consistently reported in studies and validated instruments (e.g., C19-YRS, COMPASS-31) for pragmatic clinical tracking and communication; it should not be used as a stand-alone diagnostic or for definitive risk prediction.
