Abstract 12360: Coronary Stent Information via Smartphone: A New Application Improving Health-care Quality of Patients Having Undergone Percutaneous Coronary Intervention

Abstract

Introduction: There are a huge number of patients who have been treated by percutaneous coronary intervention (PCI) with stenting. For PCI two types of stent are used commonly; bare-metal stent and drug-eluting stent. Although choice of the stent has high clinical importance, the information is usually hard to obtain because of onset of unexpected pathological events in emergency cases, the needs to concentrate on treatment of urgent disorders resulting in not enough attention paid to the information itself, and so on. The lack of the information may, however, lead to inadequate decision, i.e. interruption of antiplatelet therapy. Many studies have reported that cessation of antiplatelet medications produces in-stent thrombosis in patients, especially those with drug-eluting stent during early post-operative period. This complication might lead to a lethal condition in clinical practice. Hypothesis: Smartphone based ubiquitous system of recording coronary stent information would be useful in managing patients, who underwent percutaneous coronary intervention. Methods and Results: We developed a smartphone application archiving PCI data. The operation date and type of coronary stent are recorded in the memory of smartphone. The information will enable an optimal decision about continuation or discontinuation of medications including antiplatelet in the emergency setting. The time-series record about of PCI data can be accessed anytime and anywhere in the world. Feasibility and usefulness were evaluated by both volunteer patients and cardiologits. Eighty-six percent of PCI patients satisfied with and the 80% of cardiologists espoused this application. Conclusions: Coronary stent data recording system using smartphone technology is a simple and valuable method in managing coronary artery disease patients after interventional stent deployment. This ubiquitous application would improve health-care quality of patients who have undergone PCI.
