[Angina pectoris and the severity of coronary artery stenosis]
Insights
Stable angina pectoris strongly correlates with the severity of coronary artery disease in patients with preserved left ventricular function. This finding highlights angina as a key indicator of advanced coronary artery disease.
Area of Science:
- Cardiology
- Internal Medicine
Context:
- Investigated 146 patients with stable angina pectoris.
- Patients exhibited normal segmental and global left ventricular systolic function.
- Excluded individuals with unstable angina or prior myocardial infarction.
Purpose:
- To evaluate the relationship between angina pectoris and coronary artery disease (CAD) severity.
- To determine if stable angina indicates advanced CAD in patients with preserved cardiac function.
Summary:
- A significant correlation was observed between the presence of angina and the severity of coronary artery disease (p < 0.005).
- Stable angina pectoris served as a reliable clinical indicator of advanced coronary artery disease within this specific patient cohort.
Impact:
- Provides clinical evidence supporting the association between stable angina and advanced CAD.
- Emphasizes the diagnostic value of angina symptoms in assessing coronary artery disease severity, even with preserved ventricular function.
Abstract:
The relationship between angina pectoris and the severity of coronary artery disease was evaluated in 146 patients with normal segmental and global, left ventricular, systolic performance. None had unstable angina or a previous myocardial infarction. A strong relationship was found between angina and the severity of coronary artery disease (p < 0.005). Significant, stable, angina pectoris as a clinical symptom indicated advanced coronary artery disease in this selected group of patients.
