Abstract:
Objective To investigate the relationship between the prevalence of isolated systolic hypertension (ISH) and the stages of chronic kidney disease (CKD) in chronic kidney disease outpatient clinic.Methods CKD patients of stages 1,2,3,4 and 5 were recruited (n=626).Based on office systolic pressure (SBP) and diastolic pressure (DBP),they were classified into four subtypes:normotension (＜ 140/90 mmHg),isolated diastolic hypertension (IDH,SBP ＜ 140 mmHg and DBP ≥ 90 mmHg),ISH (SBP≥ 140 mmHg and DBP ＜ 90 mmHg) and systolic-diastolic hypertension (SDH,SBP≥140 mmHg and DBP≥90 mmHg).Results The control rate of blood pressure was 86.4％,75.6％,65.3％,51.0％ and 37.0％ at CKD stage 1,2,3,4 and 5,respectively,which decreased with the advancement of CKD.There was a stepwise increase in the prevalence of ISH (0,9.2％,23.9％,28.6％ and 37.0％ at CKD stage 1,2,3,4 and 5,respectively) and SDH (4.5％,8.4％,8.0％,17.3％,21.9％ at CKD stage 1,2,3,4 and 5,respectively).Logistic regression analysis showed that age,diabetes and CKD stages were independent predictors of ISH.Compared with CKD stage 1-2,CKD stage 3,4 and 5 showed 2.388,2.697 and 5.980 folds risk in developing ISH.Conclusion The prevalence of ISH increases correspondingly with the advancement of stages of CKD,which may partially contribute to the increased cardiovascular mortality during the progress of CKD.
