NCT00980785
Angiotensin converting enzyme inhibitors (ACE-I) are a group of blood pressure-lowering medicines. Some studies suggest that ACE-I, such as ramipril, may help prevent Alzheimer's disease (AD). The purpose of the research is to see how ramipril affects a substance in the body called beta-amyloid. Beta-amyloid is found in the brain and in the liquid around the brain and spinal cord. High amounts of beta-amyloid may be associated with a greater risk of getting Alzheimer's disease. This study will see if ramipril can lower the amount of beta-amyloid in the spinal fluid. This study will also see if ramipril affects blood vessel function and memory and thinking. The investigators hope that future studies will show whether ramipril might prevent memory loss and decrease the chance of developing Alzheimer's disease.
NCT01637623
The purpose of this study is to determine if two medicines (allopurinol and losartan) can influence heart and blood vessel health compared to placebo in patients with sleep apnea who are using continuous positive airway pressure (CPAP).
NCT02925962
The investigators propose a three-arm, pragmatic, cluster-randomized clinical trial based in primary care. Participating Primary Care Providers (PCPs) will be randomized to usual care or one of two intervention arms. The first intervention will evaluate the efficacy of an automated CDSS that utilizes the electronic health record (EHR) to facilitate triple marker test ordering, guideline implementation and BP management, compared with usual care, among patients with previous documentation of eGFRcreat \<60 ml/min/1.73m2. The second intervention goes a step further, and will evaluate whether a CDSS plus a follow-up telephone call from a pharmacist (CDSS PLUS) can improve BP management and patient CKD and NSAID toxicity knowledge among the patients with CKD, compared with CDSS alone. The primary clinical outcome is BP level, with secondary outcomes related to processes of care and patient knowledge.
