Application of pulse-indicated continuous cardiac output in patients with acute inferior wall myocardial infarction / 心血管康复医学杂志

ABSTRACT

Objective: To explore the guiding significance of transpulmonary thermodilution pulse-indicated continuous cardiac output (PiCCO) in treatment for patients with acute inferior wall myocardial infarction (AIMI). Methods: A total of 26 AIMI patients in intensive care unit of cardiology department in our hospital from Jul 2012 to Jan 2014 received PiCCO and ultrasonic cardiography (UCG) to monitor cardiac output (CO) and cardiac index (CI), and their correlation analysis. Results: When PiCCO placement and after placement 72h， PiCCO monitoring CI were （2.77±0.77）L•min-1•m-2, (3.17±0.39) L•min-1•m-2 respectively, there was significant difference（P＜0.01）, UCG measured CI were (2.49±0.64）L•min-1•m-2, (2.63±0.24) L•min-1•m-2, there was no significant difference（P＞0.05）; PiCCO monitoring CO were（4.78±1.06）L/min, (5.08±1.53) L/min respectively, there was significant difference（P＜0.05）, UCG measured CO were（4.51± 0.86）L/min, (4.57±0.91) L/min, there was no significant difference（P＞0.05）; and CI，CO measured by PiCCO were significantly higher than those of UCG group (P＜0.01 both) after PiCCO placement 72h. Conclusion: Pulse-indicated continuous cardiac output can offer more sensitive hemodynamic indexes compared with UCG, which possesses important treatment guiding significance in patients with acute inferior wall myocardial infarction and unstable hemodynamics.
