Early hospital discharge after percutaneous transluminal coronary angioplasty.

To determine the safety and efficacy of early hospital discharge after percutaneous transluminal coronary angioplasty (PTCA), 100 patients were studied prospectively. A telemetry observation unit was established to monitor patients having uncomplicated procedures. A total of 170 lesions were dilated, with a procedural success rate of 96% and a clinical success rate of 91%. There were no deaths or patients who required emergency bypass surgery. Four patients developed abrupt vessel closure in the catheterization laboratory. No major complications developed in the telemetry observation unit or after discharge. Patients with high-risk lesion morphology, based on the American College of Cardiology/American Heart Association Task Force guidelines, tended to have a lower success rate and more procedural complications. Coronary dissections were angiographically detected in 33 patients and stratified into 6 types. To reduce possible adverse sequelae, all patients with complex dissections were triaged in the catheterization laboratory to an in-patient monitored unit for additional management. Accordingly, 20 patients were admitted to an in-patient unit for extended observation. Excluding 4 patients with myocardial infarction, 75% (12 of 16) were discharged the next day. Initial experience with early discharge suggests that under proper conditions the procedure is safe and effective. Patients with complex coronary dissections who are at high risk for abrupt vessel closure can be promptly identified after dilatation and triaged to an appropriate monitoring area. Early discharge after PTCA offers more efficient use of hospital facilities and the opportunity to reduce hospital costs.
