title: Safety and cost effectiveness of combined coronary angiography and angioplasty.
abstract: If coronary angioplasty can be safely performed at the time of the initial diagnostic catheterization, it may result in shorter hospitalization stays and lower overall costs. Combined coronary angiography and angioplasty was performed electively on 733 patients between January 1, 1984, and September 1, 1988. These patients were divided into three major subgroups based upon their indications for angioplasty: 444 (61%) procedures were performed for restenosis; 190 (26%) procedures were performed in patients for unstable angina; and 99 (13%) procedures were performed in patients without unstable angina or previous angioplasty. A subset of 219 patients from this study who underwent elective combined coronary angiography and angioplasty during 1986 were compared with a matched population of 191 patients from the angiography and angioplasty as separate procedures). The success and complication rates were similar for both of these groups. Patients who underwent the combined procedure were hospitalized for a mean of 4.6 days with average total charges of $11,128, compared with 8.0 days and $13,160 for patients undergoing separate procedures (p less than 0.001). Significant savings were also realized with respect to total contrast dose, fluoroscopic time, and total procedural time. Thus in informed patients with suitable coronary anatomy, the strategy of combined angiography and angioplasty may present an opportunity for decreasing hospitalization stay, reducing total charges for revascularization, and reducing radiation exposure without compromising the safety or effectiveness of the procedure.
