Non invasive measurements of cardiac output (CO) and cardiac power index (CPI) by whole body bio impedance in patients with heart failure.
European Journal of Heart Failure Supplements ( 2012 ) UK Overview: Hemodynamic dysfunction is often used as part of the definition for heart failure (HF), predicts an adverse outcome and could be an important target for therapy but is rarely measured in routine practice, perhaps because simple, effective, inexpensive technology is lacking. We assessed the […]
Noninvasive and simple assessment of cardiac output and pulmonary vascular resistance with whole-body impedance cardiography is useful for monitoring patients with pulmonary hypertension
Background: Cardiac Power Index (CPI) is a novel parameter calculated by CI*MAP and is considered to be a reliable indicator of myocardial contractility. Previous studies done by RHC technique demonstrated that CPI is the best in-hospital mortality predictor4,5,6. The target of this study was to find whether non-invasively measured CPI has a good predictive capability […]
Baseline Granov-goor index predicts acute hemodynamic improvement during CRT optimization
Authors: Stefan Bogan, Israel Mazin, Igor Lipchenca, David Bar Lev , Osnat Gurevitz, Eyal Nof, Ilan Goldenberg, Sagit Ben Zekry, Michael Eldar, Michael Glikson, Roy Beinart Conclusion: Baseline GGI predicted acute hemodynamic improvement during NICaS guided CRT optimization. A baseline of 11.5 could be possibly used in order to outline those who may benefit from […]
Cardiac Power Index is the best hemodynamic parameter to predict 6 month mortality in non septic ICU patients
Background: Cardiac Power Index (CPI) is a novel parameter calculated by CI*MAP and is considered to be a reliable indicator of myocardial contractility. Previous studies done by RHC technique demonstrated that CPI is the best in-hospital mortality predictor4,5,6. The target of this study was to find whether non-invasively measured CPI has a good predictive capability […]
Cardiac Power Is the Strongest Hemodynamic Correlate of Mortality in Cardiogenic Shock: A Report from the SHOCK Trial Registry
Authors: Rupert Fincke , Judith S Hochman, April M Lowe, Venu Menon, James N Slater, John G Webb, Thierry H LeJemtel, Gad Cotter, SHOCK Investigators Conclusion: Cardiac power is a novel hemodynamic measure. By incorporating both flow and pressure domains, it represents the cardiac pumping ability. In the present study, cardiac power is the strongest […]
Detection of left ventricular systolic dysfunction using a newly developed, laptop based, impedance cardiographic index
Authors: Yoseph Rozenman , Renee Rotzak , Robert P Patterson Results: A GGI cutoff of 10 was 89% sensitive and 96% specific for the detection of LVSD, confirming the excellent results of the training set. Positive and negative predictive values were 78% and 98% respectively. False positives and false negatives of GGI as a predictor […]
Go with the flow
Overview: Thermodilution using a pulmonary artery catheter is considered the gold standard in measuring cardiac output. However. Drawbacks associated with the technique have prompted clinicians to seek less invasive options. But these alternatives have their own limitations. We examine the evidence on four devices that measure cardiac output using. Summary: All six studies found a […]
