• Lead Sponsor: University of Nebraska

Brief Summary

The purpose of this study is to examine the use of a home-based program to improve weight reduction after percutaneous coronary intervention (PCI) (either a cardiac stent or angioplasty procedure).

Detailed Description

Obesity is an independent risk factor for coronary disease and is prevalent among patients who undergo percutaneous coronary intervention (PCI). The significance of cardiac disease is often underestimated by patients who undergo PCI, and therefore they are more reticent in modifying their cardiac risk factors such as obesity following PCI. This issue is particularly problematic for rural populations, given that weight reduction specific programs are often not available in rural communities. The overall goal of this pilot study is to evaluate a 12 week cognitive behavioral intervention for weight reduction of overweight or obese PCI patients who participate in a rural cardiac rehabilitation (CR) program. The Maximizing Outcomes Needed After Percutaneous Coronary Intervention (PCI) Using Weight Management (MOMENTUM) intervention is comprised of 6 modules, totaling 52 daily sessions promoting weight reduction, and 4 coaching sessions over the duration of the 12 week MOMENTUM intervention. The MOMENTUM intervention will be delivered using telehealth methods (Viterion telehealth device will be used to deliver the module content and the telephone to deliver the coaching sessions). The intervention was purposively designed to overcome access barriers by using delivery modes accessible to patients in rural settings, in their home and at times convenient to their schedule. A randomized, 2-group, repeated measures experimental design will be used. Subjects who have had a PCI, are overweight or obese and enroll in a rural cardiac rehabilitation program will be randomized to either the MOMENTUM group (n=25) and or control group (usual care)(n=25). The primary aim of the study is to compare the differences between the groups on weight reduction (primary outcome), diet behavior and physical activity (secondary outcomes) over time (baseline, 16 weeks, 6 and 9 months after PCI). The second aim of the study is to to evaluate the feasibility of implementing the MOMENTUM intervention for a larger randomized controlled trial. The innovation in this pilot study is the use of technology to deliver a comprehensive cognitive-behavioral weight reduction program to those cardiac patients in rural communities who otherwise might not have access to specific weight reduction programs to improve their cardiac risk profile after an acute cardiac event, such as a PCI.
