A prioritisation system for elective coronary angiography.

Objective: To devise a clinical prioritisation system for rationing access to a cardiac catheter waiting list and to describe its performance at predicting angiographic findings and selecting patients for angioplasty or coronary artery bypass graft surgery.

Setting: Tertiary level cardiology centre.

Methods: (1) 665 consecutive patients on an elective waiting list for coronary angiography were scored using a system derived from established clinical criteria for selecting patients for coronary surgery (New Zealand/Duke).

Effects of indobufen and pentoxifylline on walking capacity and hemostasis in patients with intermittent claudication: results of six months of treatment.

Seventy-one patients with peripheral arterial occlusive disease (PAOD) were randomized into two groups of different treatment modalities. The diagnosis of PAOD was established by history of intermittent claudication, clinical examination, and by Doppler pressure assessment or lower extremity arteriography. After a three-month washout period, 35 patients (Group 1) started treatment with indobufen (400 mg per day) and 36 patients (Group 2) with pentoxifylline (600 mg per day).
