Abstract: Objective  To evaluate left ventricular diastolic dysfunction in patients with combined pulmonary resection of early left ventricular systolic and diastolic function changes. Methods   62 cases with left ventricular diastolic dysfunction in patients before surgery, 3 days after 8 days, respectively, and tissue Doppler ultrasound heart examination, testing reflect diastolic function the peak early diastolic mitral flow velocity (E), mitral peak atrial systolic blood flow velocity (A), E / A , peak early diastolic mitral annulus velocity (Em) peak late diastolic mitral annular velocity (Am), calculation of E / Em; reflect the contractile function of left ventricular ejection fraction (LVEF), mitral annular peak systolic velocity Sm. Continuous monitoring of patient vital signs after surgery. Results   Compared with the previous 3 days after surgery in patients with heart rate, E faster (P <0.05), E / A increased (P <0.05), Em was significantly lower (P <0.01), E / Em significant rise higher (P <0.01), Sm lower (P <0.05), LVEF change was not statistically significant (P> 0.05); and after eight days before surgery compared to patients with heart rate, E, E / A, LVEF and Sm changes are not statistically significant (P> 0.05), Em decreased (P <0.05), E / Em increased (P <0.05). Conclusion   The combined left ventricular diastolic dysfunction in patients early after lung resection, left ventricular systolic and diastolic functions are declining, systolic function earlier than the diastolic function returned to preoperative levels; tissue Doppler examination can be more sensitive detection changes in cardiac function.
