Abstract
Lisong Liu Qi Hua P322 Impact of ambulatory pulse pressure and office pulse pressure on left ventricular hypertrophy in patients with essential hypertension American Journal of Hypertension Volume 18 Issue S4 May 2005 Page 122A https//doiorg/101016/jamjhyper200503340422 initially untreated subjects with mild to moderate essential hypertension age 519±88 436 menwere involved in this study All subjects underwent 3 blood pressure measurements in different days ambulatory blood pressure monitoring and echocardiography 1 They were divided into four groups according to their ambulatory pulse pressure degrees group A 24h PP40mmHg group B 40mmHg≤24h PP50mmHg group C 50mmHg≤24h PP60mmHg group D 24h PP≥60mmHg 2 They were further divided into five groups according to their clinic pulse pressure levels group A Cpp40mmHg group B 40mmHg≤Cpp50mmHg group C 50mmHg≤Cpp60mmHg D 60mmHg≤Cpp70mmHg E Cpp≥70mmHg 3 Patients were divided into LVH and nonLVH group according to the level of left ventricular mass indexLVMIBoth ambulatory pulse pressure and clinic pulse pressure were significantly correlated with age history of hypertension LVMI arterial stiffness index and 24hour heart rate The formerr=0423 0173 0277 0670 –0168 p001 the latterr=0449 0165 0105 0399 –0118 p005∼001 Arterial stiffness evolved progressively with PP increase and it correlated with 24h PP much better than CPPr=0670 p001 and r=0399 p001 24h PP and 24h SBP were significantly higher in LVH group than nonLVH group 490±102mmHg vs 447±89mmHg p0001 and 1321±131mmHg vs 1265±127mmHg p0001 24h PP was associated with LVMI much stronger than clinic pulse pressurer=0277 p001 and r=0105 p005
