Clinical Report: Assessment of Coronary Artery Calcification in Elderly Patients

Overview

Expand on the methods used for evaluating the prognostic value of the Tei index, carotid IMT, and Crouse score.

Background

Coronary heart disease (CHD) is a leading cause of morbidity and mortality, particularly among the elderly population. Accurate assessment of coronary artery calcification (CAC) is crucial for early diagnosis and management of CHD. Non-invasive methods, such as echocardiography and carotid ultrasound, provide valuable insights into cardiac function and atherosclerosis, making them essential tools in clinical practice.

Data Highlights

ParameterSevere Calcification Group (n=45)Control Group (n=53)
Tei Index0.58 (0.51, 0.72)0.44 (0.35, 0.52)
IMT (mm)1.11 (0.89, 1.26)0.72 (0.62, 0.80)
Crouse Score1.83 (1.04, 2.56)0.90 (0.77, 1.09)

Key Findings

  • The severe calcification group had significantly higher Tei index, IMT, and Crouse score compared to controls (all p < 0.001).
  • Tei index, IMT, and Crouse score independently predicted severe CAC with odds ratios ranging from 2.634 to 73.061 (p < 0.05).
  • There was a positive correlation between CACS and the number of stenosed coronary vessels (r = 0.429–0.453, p < 0.01).
  • Combined ROC analysis showed superior diagnostic accuracy (AUC = 0.831) compared to individual biomarkers (AUC = 0.778–0.792).
  • High thresholds for Tei index (≥0.50), IMT (≥0.86 mm), and Crouse score (≥1.21) predicted increased MACCE risk (log-rank p < 0.001).

Clinical Implications

The integration of the Tei index, carotid IMT, and Crouse score can enhance the diagnostic precision for coronary artery calcification in elderly patients. This non-invasive approach may facilitate better risk stratification for major adverse cardiovascular and cerebrovascular events, aiding in clinical decision-making and management strategies.

Conclusion

The study underscores the importance of combining non-invasive echocardiographic and ultrasound metrics to improve the assessment of coronary artery calcification and predict adverse cardiovascular outcomes in elderly patients with coronary heart disease.
