Medical records that document a diagnosis of high-output heart failure directly support the highest rating. For the 60% level, records showing an enlarged heart on imaging, measured wide pulse pressure, and tachycardia are key. An echocardiogram, chest X-ray, or cardiac imaging report can show heart enlargement, while pulse pressure readings and heart rate measurements from clinical visits support the other two findings.
For the lower ratings, records showing chronic edema, stasis dermatitis, skin ulceration, or cellulitis in the affected limb are relevant. Photographs, wound-care notes, and dermatology records can document skin changes. Your doctor's notes or a VA examination report that identifies which limb is affected — upper or lower — matter because the percentage differs by location. Statements from you or people who know you describing how swelling or skin problems limit your daily activities can also reflect the severity of your symptoms.
