Insights
Coronary artery disease is common in patients with valvular disease, particularly older males with aortic or mitral issues. Coronary arteriography is recommended for those over 50, irrespective of chest pain.
Area of Science:
- Cardiology
- Valvular Heart Disease
- Coronary Artery Disease
Background:
- Valvular heart disease frequently coexists with coronary artery disease.
- Understanding the prevalence and risk factors for coronary artery disease in valvular disease patients is crucial for clinical management.
Purpose of the Study:
- To determine the prevalence of coronary artery disease (CAD) in patients with valvular heart disease (VHD).
- To identify demographic and clinical factors associated with CAD in this population.
- To guide recommendations for coronary arteriography in VHD patients.
Main Methods:
- Retrospective analysis of patient data including demographics, valvular lesions, and coronary arteriography results.
- Statistical analysis to assess the correlation between VHD characteristics and CAD prevalence.
Main Results:
- The prevalence of CAD in patients with VHD was 10.9%.
- CAD was more common in males, increasing age, aortic valvular disease, and mitral regurgitation, especially with chest pain.
- Significant CAD, including three-vessel disease, was rare in patients under 50 years old.
Conclusions:
- Coronary artery disease is prevalent in patients with valvular heart disease.
- Age over 50, male sex, aortic valvular disease, and mitral regurgitation are associated with higher CAD prevalence.
- Coronary arteriography should be considered for patients over 50 with valvular disease, particularly those with aortic or mitral lesions, regardless of chest pain.
Abstract:
The prevalence of coronary artery disease in valvular disease was 10.9 per cent. The prevalence of coronary artery disease was more common in males, increasing age, aortic valvular disease and mitral regurgitation with chest pain, other types of valvular lesions did not correlate with the presence of coronary artery disease. The prevalence of significant coronary artery disease especially three vessel disease was relatively rare in those aged < 50 years. We recommend performing coronary arteriography only in patients aged > 50 years regardless of symptoms of chest pain, especially in aortic valvular disease and mitral regurgitation.
