[Aortic valve disease and coronary atherosclerosis. Clinical and coronarographic study (author's transl)]
Insights
Patients with aortic valve disease frequently experience angina pectoris. Coronary artery disease is more common with aortic stenosis than aortic regurgitation, especially in younger patients.
Area of Science:
- Cardiovascular Medicine
- Cardiac Surgery
- Interventional Cardiology
Context:
- Aortic valve disease affects numerous patients requiring intervention.
- Co-existing coronary artery disease (CAD) complicates aortic valve disease management.
- Understanding the relationship between valvular and coronary pathologies is crucial for surgical planning.
Purpose:
- To evaluate the incidence of angina pectoris in patients with aortic valve disease.
- To determine the frequency of associated coronary artery disease in aortic stenosis versus aortic regurgitation.
- To explore the correlation between angina, valvular severity, and coronary atherosclerosis.
Summary:
- This study analyzed 77 patients undergoing heart catheterization for aortic valve replacement.
- High rates of angina pectoris were observed in both aortic stenosis (60%) and aortic regurgitation (50%).
- Coronary atherosclerosis was more prevalent in aortic stenosis (35%) than aortic regurgitation (15%), occurring in younger patients with stenosis. Absence of angina strongly suggested no associated CAD. Angina indicated severe stenosis/CAD in stenosis, or ventricular dysfunction/CAD in regurgitation.
Impact:
- Findings highlight the high comorbidity of angina and CAD in aortic valve disease.
- Differentiates the pattern of CAD association between aortic stenosis and regurgitation.
- Informs clinical decision-making regarding pre-operative cardiac evaluation and risk stratification.
Abstract:
77 patients with aortic valve disease have undergone heart catheterization in prevision of valve replacement: in this group the incidence of angina pectoris and the incidence of coronary artery disease associated with the valvular disease have been evaluated. The most important data resulting from out study are: 1) High frequency of angina pectoris both aortic stenosis and in aortic regurgitation: respectively about 60% and 50%. 2) The frequency of coronary atherosclerosis associated with aortic valve disease is much higher in aortic stenosis than in aortic regurgitation: respectively 35% versus 15%. 3) Coronary atherosclerosis associated with aortic stenosis frequently occurs (about 30%) also in young-aged patients (under 40 years). On the contrary in case of aortic regurgitation it occurs much more frequently in elderly patients. 4) The absence of angina both in aortic stenosis and in aortic regurgitation virtually excludes the presence of associated coronary atherosclerosis. 5) The presence of angina in aortic stenosis indicated either severe valvular stenosis or associated coronary artery disease (in this case the valvular stenosis is mild or moderate). The presence of angina in aortic regurgitation indicates either severe impairment of left ventricular performance or associated coronary atherosclerosis.
