Multi-Parameter Index (MPI), Sub-Maximal Heart and Lung Based Risk Score for Heart Disease

Abstract

Introduction: Reports confirm that CHF patient outcomes do not correlate with current monitoring parameters. However, ventilation efficiency (VEeff) has repeatedly shown to be the most powerful, independent predictor of CHF patient survival. Oxygen uptake efficiency and chronotropic response (CRI) to exercise have also shown significance in the risk prediction of CHF patients. Hypothesis: Cumulative parameters in high risk patients may provide a more meaningful risk predictive index. Methods: One hundred and fifty two symptom limited CPX tests were performed in 127 patients (age 62.2 ± 14).
