Insights

Same day discharge (SDD) after chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is increasingly feasible, with radial-only access strongly associated with SDD. This approach is safe for select patients, showing low readmission rates.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Health Services Research

Background:

  • Same day discharge (SDD) following chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has been understudied.
  • The Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS-CTO) database provides insights into this practice.

Purpose of the Study:

  • To evaluate the clinical, angiographic, and procedural characteristics of patients undergoing CTO PCI with same day discharge versus overnight observation.
  • To identify factors associated with SDD after CTO PCI.

Main Methods:

  • Analysis of 7181 patients from the PROGRESS-CTO registry who underwent CTO PCI.
  • Comparison of patient characteristics, procedural success, and adverse events between SDD and overnight observation groups.
  • Multivariable logistic regression to identify predictors of SDD and overnight observation.

Main Results:

  • The SDD rate increased from 3% in 2015 to 21% in 2022, with 13% of patients discharged same day.
  • Patients undergoing SDD were less likely to have comorbidities like heart failure, chronic lung disease, or anemia.
  • Technical success was similar between groups, but in-hospital major adverse cardiovascular events were lower in the SDD group (0.0% vs. 0.4%).
  • Radial-only access was the strongest predictor of SDD (OR: 2.45), while prior myocardial infarction and chronic lung disease were associated with overnight observation.

Conclusions:

  • Same day discharge is feasible and increasingly utilized for select patients after CTO PCI.
  • Radial-only access is a key factor facilitating SDD in CTO PCI.
  • The study demonstrates a growing trend and safety profile for SDD in this patient population.

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...
