Analysis Of The Factors Of Direct Blood Pressure And Indirect Blood Pressure Difference

Research PurposeObjective To examine the direct and indirect blood pressure, blood pressure and analyze the direct correlation between blood pressure and blood pressure difference between the impacts of indirect factors.MethodsMay 2010 in our hospital 109 cases of coronary angiography in patients, male 70 cases, 39 females, mean age (57.84±10.54) years. After the success of the artery blood pressure measured directly at the same time, the use of calibrated mercury sphygmomanometer, blood pressure measuring upper limb, SBP take Koortkoff the first sound, DBP take Koorktoff 5 tone, under normal circumstances, such as change the sound and the distance between the silencer Large (not more than 1.5kpa) subject to the sound disappeared, but continued Needless such as voice, then it change the sound value. According to coronary angiography were divided into normal group and the CHD group, divided according to whether hypertension normal blood pressure group and hypertension group.Measured height, weight, body mass index, systolic blood pressure difference between direct and indirect (SS) and direct and indirect diastolic blood pressure difference (DD). Records of cases and interrogation by smoking, drinking history, and triglyceride and cholesterol levels and other indicators. Endothelin (EF-1) of the collection, taken from the aortic root has anticoagulant plus 3ml injection tube, 30 minutes, the specimen is sent to the laboratory centrifuged to extract plasma set at low temperature freezer -20℃after the uniform numbers stored Gather all the samples to be measured after the same group. ET-1 was measured by radioimmunoassay, according to kit instructions to the formula the concentration of ET-1.Results1. direct and indirect blood pressure was significantly related to blood pressure, SBP correlation coefficient was 0.80 (P <0.001), DBP correlation coefficient was 0.56 (P <0.05). Indirect systolic blood pressure below the direct systolic SS:-51-53mmHg (4.76±20.70), an indirect diastolic blood pressure higher than the direct diastolic DD: -49-35 mmHg (-9.85±15.86).2. systolic blood pressure difference between direct and indirect influencing factors for coronary heart disease (P <0.001), body mass index (P <0.001), women (P <0.05), diastolic blood pressure difference between direct and indirect influencing factors for coronary heart disease (P <0.001), male (P <0.05).3.different degrees of coronary heart disease group systolic blood pressure difference between direct and indirect systolic blood pressure difference was statistically significant (= 64.31, "0.001); different degrees of coronary heart disease diastolic blood pressure difference between direct and indirect diastolic pressure was significantly different (F = 74.59, P <0.001).4. ET and direct - indirect systolic blood pressure difference with the correlation coefficient was 0.546 (P <0.001).Conclusion1.direct and indirect blood pressure, blood pressure significantly correlated, in which the best correlation SBP; blood pressure have underestimated the SBP, DBP overestimated the trend.2. coronary heart disease, body mass index, women are affected directly and indirectly an important factor in the difference between systolic blood pressure, and coronary heart disease, men are primarily the difference between direct and indirect related to diastolic blood pressure.3.with the severity of coronary heart disease straight - the difference between indirect blood pressure has increased.4.ET and straight - the difference between systolic blood pressure indirectly related.
