Percutaneous Coronary Intervention Clinical Trials

This is a prospective, double-blind, sham-controlled, multicenter, randomized clinical trial is to study the effects of remote ischemic preconditioning on contrast-associated acute kidney injury, functional capacity, and major adverse kidney events in in patients with congestive heart failure undergoing cardiac catheterization and/or percutaneous coronary intervention.

The purpose of this research is to find out if doing cardiac rehab at home, or a mix of cardiac rehab at home and in the clinic, is as effective as coming in to the clinic for cardiac rehab. Read Less

The goal of this clinical trial is to compare two types of exercise prescriptions in cardiac rehabilitation eligible older adults (60 years or older) with heart disease. The investigators found in a single site pilot trial (insert NCTxxx) that one exercise prescription was better and are now repeating this study in a larger population at two sites (Baystate Medical Center, Springfield MA and Henry Ford Health System, Detroit MI). The main questions the investigators aim to answer are: 1. Compare two different exercise prescriptions in cardiac rehabilitation on exercise outcomes 1. Graded exercise test +Target heart rate range prescription \[GXT-THRR\] 2. Rating of perceived exertion (RPE) 2. What is the role of psychological feedback on fitness outcomes during cardiac rehabilitation and physical activity outside of cardiac rehabilitation. 3. What are the long-term clinical outcomes between the two exercise prescriptions Participants will be asked to: * Complete surveys about physical activity, exercise anxiety, exercise efficacy, and fears about exercising * Perform fitness measures (6-minute walk test, balance tests, stand to sit tests, a 400 meter walk, and handgrip strength) * Attend at least 18 sessions of cardiac rehabilitation after they are randomized to their exercise prescription group * Wear a heart rate monitor and a physical activity monitor per study protocol Participants will be randomized (flip of a coin) to either receive a graded exercise test and psychoeducational feedback or lifestyle education (nutrition for cardiac). The graded exercise test will be used to create a personalized exercise prescription with the target heart rate range calculated from the test and the lifestyle education group will use their ratings of perceived exertion for their exercise prescription.

There are key differences today in clinical practice regarding perioperative management of post-PCI patients on DAPT undergoing NCS. Moreover, there are significant differences between bridging agents, and improved safety of current-generation DES. Given the significant limitations of current studies a well-designed registry to study current U.S. practice patterns and the bleeding or ischemic risks associated with the various perioperative DAPT management strategies including bridging and no bridging will significantly add to the understanding of the current problem and associated risks of patients. These data could form the basis for conducting future randomized clinical trials (RCTs) in this area. NCS in post-PCI patients on chronic DAPT presents a complex interaction of both ischemic and bleeding risks. The MARS registry will study the area of perioperative antiplatelet therapy management through a multicenter observational national registry designed to collect pre-operative, intra-operative and post-operative clinical strategies, therapeutic interventions and outcomes data. This proposal outlines the role of a highly experienced clinical trial team to conduct a multicenter prospective registry. This question is highly relevant to a diverse group of medical providers and millions of patients in the US and around the world; this will be the first such U.S. registry to address this critically important public health issue. Study objectives: i. To collect data on contemporary clinical practice in the U.S. on managing post percutaneous coronary intervention (PCI) DAPT in patients scheduled to undergo NCS and CS. ii. To assess ischemic and bleeding endpoints in this group of patients during the study period. iii. To generate initial data to plan for future large-scale randomized clinical trials on perioperative management of DAPT. Read Less
