Clinical Presentation & Protocol
Patient Usually Complains Of
Patient presents with progressive dyspnea, orthopnea, and peripheral edema in the setting of known or suspected hypereosinophilic syndrome (HES). Clinical history significant for persistent eosinophilia (>1500 cells/ยตL), constitutional symptoms (fatigue, night sweats), and potential thromboembolic events. Review of systems positive for palpitations or chest discomfort.
Clinical Examination Findings
Cardiovascular exam reveals elevated JVP, displaced apical impulse, and a pansystolic murmur consistent with mitral or tricuspid regurgitation. S3 gallop noted. Pulmonary exam demonstrates bibasilar crackles. Skin exam assessed for embolic phenomena or eosinophilic dermatosis. Extremities show pitting edema.
Treatment Protocol
Initiate high-dose corticosteroids (prednisone 1mg/kg/day) to reduce eosinophil burden. Anticoagulation therapy (warfarin or DOACs) indicated for intracardiac thrombus. Consider hydroxyurea or targeted tyrosine kinase inhibitors (e.g., imatinib) if FIP1L1-PDGFRA positive. Surgical consultation for endomyocardial fibrosis or valve replacement if refractory.
