Table 2 Clinical studies that investigated the relation of the spectral tissue Doppler E/E' ratio with maximal exercise tolerance

From: Current clinical applications of spectral tissue Doppler echocardiography (E/E' ratio) as a noninvasive surrogate for left ventricular diastolic pressures in the diagnosis of heart failure with preserved left ventricular systolic function

Reference Population study Number of patients Relation with PVo2 Spectral tissue Doppler index measured at rest
Matsumura79 HCM 85 -0.42* (p < 0.001) Lateral E/E' ratio
McMahon80 HCM in children 80 -0.74* (p < 0.001) Septal E/E' ratio
Ha81 HCM 29 -0.47* (p = 0.01) Septal E/E' ratio
Smart82 Chronic systolic HF 95 -0.31* (p = 0.001) Average E/E' ratio
Lee83 Permanent atrial fibrillation 73 -0.35 (p = 0.03) Septal E/E' ratio
Hadano84 Chronic LV systolic dysfunction 53 -0.68* (p < 0.001) Lateral E/E' ratio
Van de Veire85 CAD and preserved LV systolic function 142 p = 0.005 Septal E/E' ratio
Reference Population study Number of patients Relation with METs Spectral tissue Doppler index measured at rest
Skaluba86 Clinically indicated treadmill exercise 121 -0.68* (p < 0.001) Septal E/E' ratio
Burgess78 Clinically indicated treadmill exercise 166 -0.37* (p < 0.001) Septal E/E' ratio
Reference Population study Number of patients Relation with METs Post-exercise spectral tissue Doppler index
Burgess78 Clinically indicated treadmill exercise 166 -0.44* (p < 0.001) Septal E/E' ratio
  1. CAD: coronary artery disease; HCM: hypertrophic cardiomyopathy; HF: heart failure; LV: left ventricular; METs: achieved metabolic equivalents; PVo2: peak oxygen consumption during exercise.
  2. *: univariate regression analysis; : multivariate regression analysis; : analysis of variance for E/E' between quartiles of PVo2.
