Abstract

The difference in cardiac oxygen consumption between individuals with normal cardiac function and those with heart failure (HF), and the association between cardiac oxygen consumption and cardiac ejection fraction (EF) are poorly understood. By establishing a control group composed of individuals with normal cardiac function, the present study aimed to determine the difference in cardiac oxygen consumption between individuals with normal and abnormal cardiac function, as well as the association between cardiac oxygen consumption and cardiac EF. A total of 34 patients with normal cardiac function were enrolled in the control group and 44 patients with HF were enrolled in the experimental group. Blood samples from the aortic root, femoral vein and coronary sinus (CS) were collected from each patient. All the blood samples were subjected to blood gas analysis. The partial pressure of oxygen and oxygen saturation obtained from the peripheral vein and CS of patients with HF were lower than those in patients with normal cardiac function. In each patient with HF, the association between cardiac oxygen consumption and cardiac EF was analyzed using multi‑linear correlation and regression analyses. Cardiac oxygen consumption negatively correlated with cardiac EF (R=‑0.336, P=0.026). Furthermore, linear regression analysis suggested that cardiac EF had a significant effect on cardiac oxygen consumption (y = 82.906‑0.483x, P=0.026). In conclusion, myocardial oxygen consumption is greater in individuals with HF compared to those with normal cardiac function. The cardiac EF affects myocardial oxygen consumption in patients with HF.
