Laboratory investigations revealed elevated myocardial enzymes, mild renal impairment (eGFR = 55 mL/min/1.73 m2), and systemic inflammatory markers, including leukocytosis (13,620/mm3) with eosinophilia (9.5%), elevated C-reactive protein (CRP = 17.5 mg/L), and IgE levels (180 UI/mL). Here, IGHE is linked to Increased total leukocyte count.
