Randomized Controlled Trial Multicenter Study Clinical Trial
Effects of ranolazine with atenolol, amlodipine, or diltiazem on exercise tolerance and angina frequency in patients with severe chronic angina: a randomized controlled trial.
Many patients with chronic angina experience anginal episodes despite revascularization and antianginal medications. In a previous trial, antianginal monotherapy with ranolazine, a drug believed to partially inhibit fatty acid oxidation, increased treadmill exercise performance; however, its long-term efficacy and safety have not been studied in combination with beta-blockers or calcium antagonists in a large patient population with severe chronic angina. ⋯ Twice-daily doses of ranolazine increased exercise capacity and provided additional antianginal relief to symptomatic patients with severe chronic angina taking standard doses of atenolol, amlodipine, or diltiazem, without evident adverse, long-term survival consequences over 1 to 2 years of therapy.

Review Meta Analysis
Arterial puncture closing devices compared with standard manual compression after cardiac catheterization: systematic review and meta-analysis.
Arterial puncture closing devices (APCDs) were developed to replace standard compression at the puncture site and to shorten bed rest following percutaneous coronary intervention. ⋯ Based on this meta-analysis of 30 randomized trials, many of poor methodological quality, there is only marginal evidence that APCDs are effective and there is reason for concern that these devices may increase the risk of hematoma and pseudoaneurysm.

Control of blood glucose levels, blood pressure, and cholesterol levels is proven to reduce the risk of vascular disease among individuals with diabetes mellitus; however, the current state of control of these risk factors among individuals in the United States is uncertain. ⋯ Further public health efforts are needed to control risk factors for vascular disease among individuals with diagnosed diabetes.
