| Objective：To impact of chronic obstructive pulmonary disease on leftventricular diastolic function with the morbidity of left ventricular diastolic functionin chronic obstructive pulmonary disease patients.Methods：Select patients who were hospitaled and accepted echocardiography,age≥60years, LVEF>45%, at the Beijing Friendship Hospital cadres healthcarecenter during December2011and December2013. According to past history, thestudy group:①chronic obstructive pulmonary disease group (COPD group);②normal group(NOR group). According to GLOD criteria COPD group is dividedinto GOLDⅠ-Ⅱgroup and GOLDⅢ-Ⅳgroup.Multra measure left ventricular wallthickness, septal thickness, left ventricular internal diameter measurement withimproved Simpson2section left LVEF; mitral inflow E peak, A peak pulse Dopplermeasurement; Tissue Doppler imaging in mitral annular interventricular septum,sidewall, two measuring myocardial long axis of early diastolic peak speed (Em);calculate the E/A, E/Em, left ventricular wall mass index. SPSS17.0statisticalanalysis, P <0.05was considered statistically significant.Results：①collected148cases of elderly patients, COPD group was75cases,NOR group was73cases, left ventricular diastolic dysfunction prevalence was65.6%in COPD group, the prevalence of HFPEF was54.1%.②Compared with the NORgroup, COPD patients were older, pulmonary artery systolic pressure increased,theE’decreased, E/E’ and the difference was statistically significant (P<0.05).③Compared with the NOR group,left ventricular wall mass index was increased inCOPD group, the difference was statistically significant (P<0.05).Conclusion：①Compared with patients of NOR group, the rate of left ventricular diastolic function and HFPEF in COPD group increased.②TDI with other measuresis useful to diagnose diastolic function in COPD patients.③COPD is the risk factorsof left ventricular diastolic dysfunction.④COPD patients had changed concentrichypertrophy of left ventricular,... |
