Abstract:
Objective To investigate the characteristics of pulse wave velocity(PWV)and heart rate variability (HRV)and evaluate their feasibility in grading the cardiovascular risk in patients with isolated systolic hypertension (ISH).Methods Eighty-nine ISH patients and systolic-diastolic hypertension patients(DH,n=98)admitted in our hospital were submitted carotid-radial PWV(crPWV),carotid femoral PWV(cfPWV)and HRV,ISH patients were categorized depending on their risk grade as:low risk group(n=3),moderate risk group(n=17),high risk group(n=35)and very high risk group(n=34).Results The cfPWV in ISH patients is significantly higher than that of sys-diastolic hypertension group(ISH: 399.6?48.2 vs sys diastolic hypertension:374.3?39.7 cm/s,P0.05).The LF in ISH group are markedly higher than those in DH(ISH:4.35?1.07 log ms~2 vs 3.78?0.82 log ms~2,P 0.05).LF are markedly positive correlated with the degree of the total cardiovascular risk(rs=0.438,P
