Table 3 Uni- and multivariable analysis for the prediction of heart failure stages. Absolute values are reported for all correlation coefficients

From: Left and right ventricular strain using fast strain-encoded cardiovascular magnetic resonance for the diagnostic classification of patients with chronic non-ischemic heart failure due to dilated, hypertrophic cardiomyopathy or cardiac amyloidosis
