This study of cardiovascular disease in adults investigates the interdependence and relative impacts of two specific medical interventions for coronary artery disease (CAD) patients. The goal of this study is to determine the extent to which invasive CAD procedures have favorable economic cost and quality-of-life related outcomes with a specific focus on the economic cost and quality-of-life related impacts of percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) surgery, taking into account both quantitative and qualitative measures and outcomes. According to the American Heart Association, the problem of cardiovascular disease affects over 30% of adults in the U.S. with an economic cost of $503.2 billion in 2010. However, despite the magnitude of the cardiovascular disease problem, there have been relatively few comparative effectiveness studies on CAD treatment, and even fewer investigating costs and benefits (both direct and indirect). Specifically, there is a need to better understand the future impact of these treatments on future healthcare spending and the economic outcomes of cardiovascular health promotion. This study contributes to existing literature by using recent data to conduct statistical calculations on the differences in hard outcomes between PCI and CABG procedures. Furthermore, this study compares differences and significance levels in both long and short-term outcomes, suggesting policy recommendations based on the results of this study. Finally, this study recommends a direction for future research on coronary artery disease and appropriate considerations for future research to take into account. This study will use data collected in existing studies and databases and use statistical analyses and calculations to develop a cost-benefit analysis of cardiovascular disease. The principal questions addressed in this study are: 1) Based on current conditions, the health of U.S. adults, and the medical technology and resources at our disposal, what costs and benefits can be expected for coronary artery disease patients? 2) What are the comparative costs, benefits, and effectiveness of current treatment options? This study found that it is reasonable to assume that, when controlling for age, mean life expectancies between CABG and PCI patients do not differ significantly. Although quality-of-life outcomes among CABG patients were generally superior to PCI patients one year after the procedures, this study discovered that both quantitative and qualitative long-term outcomes do not differ significantly between CABG and PCI patients. Therefore, this study highlights the importance of considering long-term outcomes when making medical decisions by showing that although hospital charges for CABG surgery far exceed charges for PCI initially, a greater need among PCI patients for repeat procedures contributes to similar long-terms costs between these two procedures.
