Comparison of noninvasive measurements of human cardiac mechanical work with prior studies employing catheterization techniques, ultrasound and cardiac MRI

Eff efficiency, HF congestive heart failure (prior studies, pink highlight), DCM dilated cardiomyopathy, MI prior myocardial infarction, CAD coronary artery disease, CM cardiomyopathy; HYPT hypertension, LVH left ventricular hypertrophy, HCM hypertrophic cardiomyopathy, gen genetic origin, isch patients with ischemia. Prior studies of patients who did not have heart disease are highlighted in green. *P < 0.05 vs. controls. ^aConverted to SI units from mmHg.ml using a factor of 1.333 × 10^–4. ^bUsed conductance and/or pressure catheter. ^cUsed cine CMR for volumetry. ^dUsed echocardiographic volumetry
