Candesartan treatment for peripheral occlusive arterial disease after stent angioplasty : a randomised, placebo-controlled trial.

Objectives: In this prospective, double-blind, placebo-controlled study we observed the influence of treatment with candesartan 8mg on restenosis rates after stent implantation into the femoral artery 6 months after percutaneous transluminal angioplasty (PTA). We hypothesised that angiotensin II type 1 (AT1)-receptor blockade with candesartan would reduce restenosis rates by reducing angiotensin II-mediated intima hyperproliferation within the stented vessel segment in patients with peripheral occlusive disease.

Patients And Methods: Eighty-seven patients with peripheral occlusive arterial disease stage IIb who had been successfully treated with PTA and stent implantation were randomised to receive orally either candesartan 8mg (n = 44) or placebo (n = 43).

Use of abciximab and tirofiban in patients with peripheral arterial occlusive disease and arterial thrombosis.

Acute peripheral arterial occlusive disease is an important factor affecting the mobility and mortality rate of elderly patients. Catheter-guided arterial thrombolysis in these patients has its limitations: long lysis times, early occlusions, and high restenosis rates. The study investigated whether the use of tirofiban has the same favorable effect as the glycoprotein (GP) IIb/IIIa receptor antagonist abciximab and whether lysis times can be shortened and the disease course positively influenced by these substances.

Potential use of a low-molecular-weight heparin to prevent restenosis in patients with extensive wall damage following peripheral angioplasty.

The long-term outcome of primary successful percutaneous transluminal angioplasty (PTA) for patients with peripheral occlusive arterial disease (POAD) is frequently compromised by the development of restenosis, especially when extensive dissections result from the angioplastic procedure. Unfortunately, prevention of the occlusive process by means of drugs such as antithrombotics, anticoagulants, thrombolytics, corticosteroids, lipid reducers, or cytostatics has not been demonstrated convincingly. The authors sought to clarify whether such patients could benefit from the postsurgical administration of low-molecular-weight heparin.

Short- and long-term results of abciximab versus aspirin in conjunction with thrombolysis for patients with peripheral occlusive arterial disease and arterial thrombosis.

Acute peripheral occlusive arterial disease is an important cause of morbidity and mortality, particularly among older persons. Catheter-directed thrombolytic therapy is the treatment of choice but has limitations: long lytic times, occlusions refractory to thrombolysis, and a high rate of restenosis. We conducted a pilot study to evaluate the use of the platelet GP IIb/IIIa receptor antagonist abciximab versus aspirin in conjunction with thrombolysis in patients with acute peripheral occlusive arterial disease associated with arterial thrombosis.

Short- and long-term results after thrombolytic treatment of deep venous thrombosis.

Objectives: The goal of this study was to assess the short- and long-term efficacy of different thrombolytic therapy regimens in patients with leg or pelvic deep venous thrombosis (DVT).

Background: It is unclear whether locoregional or systemic thrombolysis is superior in treating acute leg DVT or even whether lysis is more effective than anticoagulation therapy in preventing postthrombotic syndrome.

Methods: A total of 250 patients averaging 40 years of age with acute DVT were randomized into five groups to receive full heparinization (1,000 IU/h) and compression treatment, with four groups also administered locoregional tissue plasminogen activator (20 mg/day) or urokinase (100,000 IU/day) or systemic streptokinase (3,000,000 IU daily) or urokinase (5,000,000 IU daily).
