Insights

Urgent coronary artery bypass grafting (CABG) carries a high in-hospital mortality risk. However, patients who survive urgent CABG can achieve a favorable 10-year survival rate, highlighting the importance of prompt intervention.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Medical Outcomes Research

Background:

  • Urgent coronary artery bypass grafting (CABG) is associated with increased mortality compared to elective procedures.
  • Prompt surgical revascularization is critical for patients with acute coronary conditions.

Purpose of the Study:

  • To evaluate the clinical outcomes of patients undergoing urgent coronary artery bypass grafting (CABG).
  • To identify preoperative risk factors associated with mortality in urgent CABG patients.

Main Methods:

  • Retrospective analysis of 104 patients who underwent urgent CABG between July 1992 and May 2005.
  • Comparison of preoperative characteristics and postoperative outcomes between survivors and non-survivors.
  • Identification of independent risk factors for mortality using logistic regression.

Main Results:

  • In-hospital mortality rate for urgent CABG was 17.3% (18/104), with low cardiac output being the most common cause of death.
  • Independent preoperative risk factors for mortality included advanced age (>70 years), preoperative shock, and low ejection fraction (<40%).
  • The 10-year actuarial survival rate for patients who underwent urgent CABG was 61%.

Conclusions:

  • Despite a high operative mortality, urgent CABG can lead to favorable long-term outcomes for survivors.
  • Early identification and management of risk factors are crucial for improving outcomes in urgent CABG patients.
