[Outcome of patients with inoperable multivessel coronary disease]
Insights
For patients with complex coronary artery disease unsuitable for surgery, 6-year survival was 58%. Left ventricular abnormalities, not ejection fraction, significantly impacted survival and cardiac events.
Area of Science:
- Cardiology
- Vascular Medicine
- Clinical Prognosis
Context:
- Focuses on 100 patients with two or three vessel coronary artery disease.
- Excludes patients suitable for surgical intervention due to distal vascular bed quality or depressed left ventricular function.
Purpose:
- To evaluate the clinical course and long-term outcomes of patients with coronary artery disease (CAD) who are not candidates for revascularization surgery.
- To identify key prognostic factors influencing survival and cardiac events in this high-risk population.
Summary:
- A 6-year actuarial survival rate of 58% was observed in the studied cohort.
- 43% of patients remained free from serious cardiac events, including death or hospital readmission.
- Significant prognostic factors included the clinical course severity in women and pre-existing heart failure.
- Left ventricular kinetic abnormalities were found to be more predictive of survival and recurrent coronary events than ejection fraction or coronary lesion severity.
Impact:
- Highlights the importance of assessing left ventricular function beyond ejection fraction for risk stratification.
- Provides crucial data for managing patients with advanced coronary artery disease who have limited treatment options.
- Informs clinical decision-making and patient counseling regarding prognosis in non-surgical CAD cases.
Abstract:
The authors studied the clinical course of 100 patients with two or three vessel coronary artery disease who were unsuitable for surgery because of the poor quality of the distal vascular bed or excessively depressed left ventricular function. The 6 year actuarial survival was 58 per cent; 43 of the 100 patients did not present any serious cardiac events causing death or requiring further admission to hospital, over this follow-up period. The severity of the clinical course in women and the presence of heart failure prior to coronary angiography were considered to be among the most important clinical prognostic factors. On the basis of the haemodynamic survey, the probability of survival or the risk of a further coronary accident appears to depend more on the extent of the left ventricular kinetic abnormalities than on the ejection fraction or the severity of the coronary lesions.
