Comparative Prediction of Cardiac Events by Wall Motion, Wall Motion Plus Coronary Flow Reserve, or Myocardial Perfusion Analysis A Multicenter Study of Contrast Stress Echocardiography .

Conclusions The multiparametric assessment of WM, CFR-LAD and MP during stress testing in patients with known or suspected coronary artery disease is feasible. Contrast SE allowed better prognostication, irrespective of the use of CFR-LAD or MP. The addition of either CFR-LAD or MP assessment to standard WM analysis and clinical parameters yielded progressively higher values for the prediction of cardiac events and may be required in today's intensively treated patients undergoing SE, because their average low risk of future cardiac events requires methods with higher predictive sensitivity than that available with standalone WM assessment.

A saga da perfusão com contraste continua. O problema da perfusão é ter que desbancar a forte presença prognóstica e diagnóstica da alteração da contratilidade!

Melhor mesmo é usar o contraste para enxergar de verdade o espaço negativo e acertar 100% das alterações segmentares.
