Perioperative sequential monitoring of hemodynamic parameters in patients with pheochromocytoma using the NICaS
Authors: Yayoi Matsuda, Hisaya Kawate, Shingo Shimada, Chitose Matsuzaki, Hiromi Nagata, Masahiro Adachi, Keizo Ohnaka, Masatoshi Nomura, Ryoichi Takayanagi Conclusion: The results of this study show the potential usefulness of sequential monitoring of hemodynamic status using NICaS in patients with pheochromocytoma during the perioperative period. Despite some limitations, NICaS-derived CO seems to be applicable to […]
Non-invasive measurement of cardiac output by whole-body bio-impedance during dobutamine stress echocardiography: Clinical implications in patients with left ventricular dysfunction and ischemia
Authors: Gad Cotter, Marina Laitman, Edgar Sucher, Eli Peleg, Edo Kaluski, Ruth Wolf, Zvi Vered Conclusion: Measurement of CI by NICaS correlated well with Doppler-derived CI. The calculation of Cpi and TPRI changes during dobutamine stress may provide important clinical information. For the full article click here
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 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 […]
