A Man With Leg Pain
A 68-year-old man presents to the clinic with pain in the left calf that starts after walking two blocks on the way to his neighborhood grocery store. After 5-10 minutes of rest, he feels relief and can walk another block to the store. His medical history is positive for type 2 diabetes mellitus (T2DM), hypertension (HTN), and chronic kidney disease (CKD). His medications include an angiotensin-receptor blocker, calcium channel blocker, simvastatin, and sodium-glucose cotransporter-2 inhibitor.
His blood pressure is 136/85 mm Hg, heart rate is 76 bpm, and oxygen saturation on room air is 95%. Complete blood count values are within the reference ranges, creatinine level is 1.2 mg/dL, hemoglobin A1c concentration is 7.3%, and low-density lipoprotein level is 74 mg/dL. An ankle-brachial index is performed, which reveals values of 0.68 on the left leg and 0.89 on the right.
Aspirin is added to his medications and simvastatin is replaced with rosuvastatin.
