Giant Cell Myocarditis Biopsy Sensitivity

Estimate endomyocardial biopsy sensitivity for giant cell myocarditis (GCM). Sensitivity is 82-85% with sampling error due to patchy disease; multiple biopsies improve yield.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.
