[Death rate on a heart surgery waiting list]

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Clinical Outcomes Research

Context:

• Aorto-coronary bypass (CABG) surgery is a critical intervention for severe coronary heart disease.
• Waiting lists for CABG procedures can involve significant delays, raising concerns about patient outcomes.
• Pre-operative mortality is a key metric for assessing the effectiveness and timeliness of surgical interventions.

Purpose:

• To determine the incidence of pre-operative mortality among patients awaiting CABG surgery.
• To identify clinical indicators associated with increased risk of death while on the waiting list.
• To evaluate the prognostic significance of these indicators in relation to waiting times.

Summary:

• A study of 2398 patients awaiting CABG found that 42 (1.8%) died before surgery, with an average waiting time of four months.
• Patients who died pre-operatively exhibited a higher frequency of advanced coronary heart disease indicators, including angina at rest, three-vessel disease, main stem stenosis, and left ventricular contraction abnormalities.
• These indicators demonstrated significant prognostic value, particularly when considering varying waiting periods for different patient subgroups.

Impact:

• Identifies high-risk patient profiles for pre-operative mortality in CABG waiting lists.
• Highlights the need for efficient waiting list management and timely surgical intervention.
• Provides valuable data for risk stratification and resource allocation in cardiovascular care.
