The patient states that his calves have been hurting more and more over the last two months. The pain isnt present at rest, but the pain develops as the patient starts walking and exerting himself. He states that stopping to rest is the only thing that relieves the pain. Of note, the patients medical history is significant for 30-pack-years of smoking, hypertension, hyperlipidemia, and a previous myocardial infarction status-post angioplasty and stent. On exam, the patients lower legs below knee have glossy skin with loss of hair. The dorsalis pedis pulses are barely palpable bilaterally. Which of the following is the best initial therapy for this patient?? A: Lifestyle modifications, B: Cilostazol, C: Clopidogrel, D: Angioplasty and stenting, E: Arterial bypass surgery,  <response>: This is a question about peripheral artery disease PAD presenting as intermittent claudication. The key findings in the stem are calf pain with exertion that is relieved by rest, history of smoking, and diminished pedal pulses. These point to PAD as the likely diagnosis. The choices include medications like cilostazol and clopidogrel, endovascular procedures like angioplastystenting, bypass surgery, and lifestyle modifications. For initial management of claudication, conservative medical therapy and lifestyle changes are preferred over invasive procedures. Cilostazol can improve symptoms and walking distance in some patients with claudication, making it a reasonable option. Clopidogrel is an antiplatelet but does not have a specific role in treating claudication itself. Therefore, the best initial therapy is lifestyle modifications.A: Lifestyle modifications
