Objective: To study in elderly hypertensive patients in the case of different duration of hypertension, different blood pressure grades , different types of blood pressure rhythm and different left ventricular configuration , left atrial volume and left ventricular volume changes . Methods: The echocardiographic examination of 129 cases of elderly patients with hypertension and 125 the physical examination normotensive elderly left atrial volume and left ventricular volume measurements , analyze their differences ; , and elderly hypertensive patients with ambulatory blood pressure monitoring ; compare different rhythm types cases in different course , a different classification , different left ventricular geometric patterns and blood pressure , left atrial volume and left ventricular volume changes . Results : 1 ) hypertension group left atrial volume ( LAV ) , left atrial volume index ( LAVI ) , left ventricular end-systolic volume ( ESV ) , left ventricular end-diastolic volume (EDV) compared with the control group were increased , the difference statistically significant (P lt; 0.05); 2) hypertension group left ventricular geometry abnormal LAV and LAVI , ESV, compared to the the EDV normal configuration are increased , the difference was statistically significance ( P lt ; 0.05) ; 3 ) 2 hypertension group LAV and LAVI EDV and a hypertension were increased, and the difference was statistically significant ( P lt; 0.05 ) . ESV difference between the two groups had no statistical significance ( P gt ; 0.05) ; 4 ) in elderly hypertensive patients with the course of growth , the left LAV LAVI , ESV , EDV, showed increasing trend , the difference was statistically significant ( P lt; 0.05); 5) non-dipper group ESV and EDV than dipper group increases, the difference was statistically significant ( P lt; 0.05 ) . However, the volume of the left atrium , left atrial volume index difference between the two groups was not statistically significant (P gt; 0.05). Conclusion : the elderly hypertensive disease duration and non-dipper circadian rhythm important impact on left ventricular geometry ; associated with changes in left atrial volume and left ventricular volumes and changes in left ventricular geometry ; course of hypertension on left atrial volume and left ventricular volume changes have an impact , and some indicators of changes in blood pressure levels and non-dipper circadian rhythm only influential .
