Post-acute Myocarditis Persistent Inflammation Score (MRI + Biomarkers) Calculator

Post-acute Myocarditis Persistent Inflammation Score (MRI + Biomarkers): Explanation and Clinical Context This calculator provides a pragmatic, literature-informed composite score to estimate the likelihood of persistent myocardial inflammation after an acute myocarditis episode using follow-up cardiovascular magnetic resonance (CMR) features and blood biomarkers. It weights factors consistently linked with adverse o

Post-COVID Arrhythmia Risk Model (Autonomic + ECG) Calculator

Post-COVID Arrhythmia Risk Model (Autonomic + ECG): Explanation and Clinical Context This model integrates autonomic markers (HRV indices) and ECG variables to estimate post-acute arrhythmic risk in individuals recovering from COVID-19. Reduced HRV (low SDNN, RMSSD) reflects sympathetic predominance and vagal withdrawal, patterns observed in post-COVID dysautonomia. QTc prolongation captures impaired repolarization r

Post-COVID Cardiac Symptom Burden Score (Composite) Calculator

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,

Post-COVID Microvascular Dysfunction Index (Stress Perfusion Surrogate) Calculator

Quantitative CMR Perfusion Inputs (preferred) Enter global myocardial blood flow (MBF) from quantitative CMR perfusion mapping. Post-COVID Microvascular Dysfunction (Stress Perfusion Surrogate): Explanation and Clinical Context This calculator estimates microvascular function using quantitative stress perfusion metrics. The primary output is myocardial perfusion reserve (MPR), computed from global stress and rest myo

Post-COVID Thrombotic Risk Composite (D-dimer + Clinical) Calculator

Post-COVID Thrombotic Risk Composite (D-dimer + Clinical): Explanation and Clinical Context This calculator applies the IMPROVE-DD model, combining clinical factors with D-dimer elevation (≥2× ULN) to estimate venous thromboembolism (VTE) risk in post-COVID patients. Clinical Significance: High scores identify patients who may benefit from extended prophylaxis with rivaroxaban 10 mg daily for 35 days post-discharge (

Post-infectious Autoimmune Cardiac Risk Index (Autoantibodies Panel)

: Explanation and Clinical Context Post-infectious autoimmune cardiac disorders represent a spectrum of myocardial and endocardial injury that follows infectious triggers such as viral myocarditis, bacterial infections, or systemic inflammatory responses. The immune system, after pathogen clearance, may continue to recognize cardiac antigens as foreign due to molecular mimicry between microbial epitopes and myocardia
