Objective To analyze the distribution features of systemic vascular resistance(SVR)disorder in healthy subjects at Guangxi province.Methods SVR and systolic blood pressure(SBP),diastolic blood pressure(DBP),mean arterial pressure(MAP),pulse pressure(PP),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 measured with Bioz.com Cardio Dynamics.Results The incidence of SVR disorder in youngster and elder was higher than other subjects.The prevalence of SVR disorders was more among females than among males(P

OBJECTIVETo compare the differences in stroke volume (SV) and stroke volume index (SI) between Han and Korean-Chinese and to investigate the correlated risk factors.
METHODSA total of 1 647 Han and 876 Korean-Chinese aged 10-80 years were investigated. SV, SI, cardiac output, cardiac output index, heart rate (HR), systemic vascular resistance (SVR), systemic vascular resistance index (SVRI), and blood pressure were measured.
RESULTSSV/SI values in Korean-Chinese were lower than those in the Han of the same sex and age. Covariance analysis showed that, apart from the effect of sex, age and body mass index (BMI), the differences in SV and SI between the two cohorts were still significant (P<0.001). Multiple regression analysis revealed that the SV difference between the two ethnicities was affected (in descending order from a strong to weak correlation) by SVR, SVRI, HR, diastolic blood pressure, mean arterial pressure, BMI, and systolic blood pressure, while the SI difference was affected by SVR, SVRI, HR, mean arterial pressure, diastolic and systolic blood pressure, and BMI.
CONCLUSIONThe Fact that SV and SI in Korean-Chinese are lower than those in Han is related with higher SVR, HR and blood pressure in the Korean-Chinese.
