[Death rate on a heart surgery waiting list]
Insights
Patients awaiting coronary artery bypass grafting surgery face mortality risks. Indicators of advanced coronary heart disease, such as angina at rest and severe blockages, predict higher pre-operative death rates.
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.
Abstract:
Of 2398 patients on a waiting list for aorto-coronary bypass operation 42 (1.8%) died before operation during an average waiting time of four months. Comparing the diagnostic data of those who died on the waiting list and those after operation, there was an increased frequency of indicators to further progression of the coronary heart disease (angina at rest, three-vessel disease, main stem stenosis, left ventricular contraction abnormalities) in the group of those patients who had died on the waiting list. The significance of these various indicators was further high-lighted in their prognostic significance when taking into account different waiting periods of the various sub-groups.
