Abstract: ABSTRACT:Objective To analyze the distribution features of systemic vascular resistance (SVR) disorder in healthy subjects in Hebei province. Methods SVR and systolic blood pressure (SBP),diastolic blood pressure (DBP),mean arterial pressure (MAP),pulse pressure ( PP),heart rate (HR),cardiac output (CO),cardiac index(CI),stroke volume (SV),stroke index (SI),left ventricular ejection time (LVET),left cardiac work (LCW) and cardiovascular function were determined with Bioz.com Cardio Dynamics. Total cholesterol (TC),triglyceride (TG) and influencing factor were tested by automated hematology analyzer in 999 healthy subjects living in Hebei province. Results SVR disorder gradually increased with the ageing in healthy subjects and the prevalences of SVR disorders was higher among females than among males (P<0.001). SVR was positively correlated with SBP,DBP,MAP,PP,LVET,body mass index (BMI),TC,and TG,and was inversely associated with HR,CO,CI,SV,SI,LCW,and arterial compliance (AC). CO and MAP were independent influencing factors with SVR. Conclusion SVR disorder is associated with age,sex,and blood pressure in populations in Hebei province and may be a marker of vascular injury.
