Feasibility and safety of same-day discharge after percutaneous coronary intervention: a tertiary care center experience.

The exponential increase in percutaneous coronary intervention (PCI) and increasing use of the transradial approach has set an ideal scenario for the cost-effective and relatively safe same-day discharge (SDD) policy in various institutes. We hereby report a single-center, prospective, observational study of 628 consecutive PCI patients, who had SDD or had overnight observation followed by next day discharge (NDD). Patients of chronic stable angina (CSA), unstable angina, and acute myocardial infarction (MI) were enrolled in the study. The baseline characteristics, safety, feasibility and 6 weeks of clinical outcomes were assessed in the two groups. Out of the 628 patients, 187 (30%) had SDD, and 358 (57%) had NDD. Transradial access was significantly more in SDD compared to NDD (P<0.001). The syntax score was significantly higher in NDD compared to the SDD (P<0.001). Five patients of NDD had clinical events at 6 weeks of follow-up, while none of SDD had any events. Patients with unstable angina (P = 0.024), MI (P≤0.001), prior PCI (P = 0.037), femoral access (P = 0.012), and high syntax score (P = 0.001) were more frequently discharged on next day. Factors such as CSA (P = 0.991), type of lesion (P = 0.984) and left ventricle ejection fraction (P = 0.535) were not the limiting factors for SDD. The present study demonstrated that SDD is safe and feasible in CSA patients, and a careful pre- and post-procedural risk assessment could enable SDD even in the complex cases.
