Cardiac MR imaging showed excellent agreement with echocardiography for assessing diastolic dysfunction (Kappa 0.931) and significantly correlated with the extent of myocardial scarring (p=0.028).
Cross-Sectional (n=40)
Does CMR accurately assess left ventricle diastolic dysfunction compared to echocardiography in patients with ischemic heart disease?
CMR provides high diagnostic accuracy comparable to echocardiography for assessing diastolic dysfunction in ischemic heart disease, while additionally allowing correlation with myocardial scarring.
Effect estimate: Kappa 0.931, Spearman 0.492
p-value: p=0.028
Objective: To detect the value of cardiac MR imaging in assessment of left ventricle diastolic function in patients with ischemic heart disease compared to echocardiography and to correlate the degree of dysfunction to the extent of myocardial scarring. Patients and methods: We examined 40 patients with known coronary artery disease. Mean patient’s age was 48 ± 10. All patients were subjected to 2D echocardiography and CMR including transmitral flow and left atrial planimetry. The degree of diastolic dysfunction was detected and correlated with the echocardiographic results and the extent of myocardial scarring. Results: On CMR, 35% of the cases had grade I diastolic dysfunction, 35% showed grade II, 15% had grade III while 15% showed normal diastolic function. CMR showed 94.12% sensitivity, 100% specificity and 95% accuracy. Excellent agreement with echocardiography was detected (Kappa coefficient 0.931). There was a significant correlation between the degree of diastolic dysfunction and the extent of myocardial scarring with Spearman’s correlation coefficient of 0.492 and p = 0.028. Conclusion: CMR has comparative results to echocardiography in assessment of diastolic dysfunction. We found a significant correlation between the degree of diastolic dysfunction and the extent of myocardial scarring.
Behairy et al. (Sat,) conducted a cross-sectional in Ischemic heart disease (n=40). Cardiac MR imaging (CMR) vs. 2D echocardiography was evaluated on Agreement with echocardiography for diastolic dysfunction and correlation with myocardial scarring (Kappa 0.931, Spearman 0.492, p=0.028). Cardiac MR imaging showed excellent agreement with echocardiography for assessing diastolic dysfunction (Kappa 0.931) and significantly correlated with the extent of myocardial scarring (p=0.028).
