Objective:To evaluate comprehensively left ventricular diastolic function in elderly patients with Echocardiography Figure and TDI technology, analysis and compare the incidence, risk factors, cardiac structure, function impairment of the similarities and differences in ADD and HFPEF patients, to find a breakthrough to prevent or delay the occurrence and development of heart failure.Methods:Select patients who were hospitaled and accepted echocardiography, age≥60years, LVEF>45%, at the Beijing Friendship Hospital cadres healthcare center during December2011and December2012. According to echocardiography results, the study group:①diastolic function in the normal group (CON group);②diastolic dysfunction group (DD group), according to whether the heart failure symptoms or signs are divided into elderly HFPEF group and elderly ADD group. M ultra measurement of left ventricular wall thickness, septal thickness, left ventricular internal diameter measurement with improved Simpson2section left LVEF; mitral inflow E peak, A peak pulse Doppler measurement; 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. SPSS17.0statistical analysis, P<0.05was considered statistically significant.Results:①collected275cases of elderly patients, CON group was41cases, DD group was234cases, among them HFPEF patient were130cases, the left ventricular diastolic dysfunction prevalence was86.03%in elderly population, the HFPEF prevalence was47.27%.②Compared with the normal diastolic function elderly, DD patients were older, hypertension disease incidence rate was high, the E’decreased, E/E’and left ventricular wall mass index increased, the difference was statistically significant (P<0.05); the age and hypertension was associated with left ventricular diastolic dysfunction.③Compared with patients of group ADD, HFPEF patients, who were older, higher smoking rate, higher hypertension, higher coronary heart disease rate, higher chronic kidney disease rate, and higher chronic obstructive pulmonary disease incidence rate, left atrial diameter, left ventricular diameter, left ventricular wall mass index all increased, E/E’, LVEF, E/A, E’ all reduced, the difference was statistically significant (P<0.05); chronic obstructive pulmonary disease, coronary heart disease, chronic renal failure and hypertension were risk factors of heart failure significantly.Conclusion:①left ventricular diastolic dysfunction prevalence was86.03%in elderly people, the prevalence of HFPEF was47.27%.②the risk factors of left ventricular diastolic dysfunction were age and hypertension; the main risk factors of HFPEF were COPD, coronary heart disease, chronic renal dysfunction and hypertension.③Elderly patients with diastolic dysfunction had changed concentric hypertrophy of left ventricular, patients with HFPEF also existed changes in left atrial structure.④even though the diastolic function showed normal, patients may also have injured in active relaxation function of left ventricular; E/E’was better correlation with HFPEF than other echocardiography parameters.
