This study evaluated a device for blood pressure measurement using high definition oscillometry (HDO) for its acceptability and practicability in the horse. Furthermore, we evaluated whether this device can determine differences in blood pressure between healthy horses and horses with heart diseases and between different measurement times.
The study population consisted of 60 horses (aged 4-31 years). All horses underwent clinical examination, conventional echocardiography (including cardiac output measurement at the pulmonary artery), repeated noninvasive blood pressure measurement at the coccygeal artery (measurement of systolic [SAP], diastolic [DAP] and mean [MAP] arterial blood pressure) and Doppler sonographic measurement of arterial blood flow at the lateral digital artery. Thirty horses were considered to be cardiologically healthy based upon previous examination. In 30 horses, various heart diseases (mitral valve insufficiency, aortic valve insufficiency and atrial fibrillation) were diagnosed. The diurnal variations in blood pressure in 18 healthy horses and 18 horses with heart disease were determined in the morning and evening. In three horses suffering from atrial fibrillation, the blood pressure was determined before and after successful cardioversion.
In healthy horses the following mean blood pressures were found: SAP 118 ± 21 mmHg, DAP 70 ± 19 mmHg and MAP 87 ± 19 mmHg. No significant difference was found between healthy horses and horses with heart diseases. An insufficiency of the aortic valve tended to result in a higher SAP (p = 0.05), whereas atrial fibrillation lowered blood pressure compared to healthy horses. With respect to the diurnal rhythm of the blood pressure, healthy horses displayed a slight increase in the systolic arterial pressure in the evening.
The HDO-sphygmomanometer facilitates a straightforward, indirect way to determine blood pressure that delivers meaningful values. However, the method is unsuited to monitor the development or therapy of cardiac diseases.
本研究评估了一种采用高清示波法（HDO）测量血压的设备在马匹中的可接受性和实用性。此外，我们还评估了该设备能否确定健康马匹与患心脏病马匹之间以及不同测量时间的血压差异。
研究群体包括60匹马（年龄4至31岁）。所有马匹均接受临床检查、传统超声心动图检查（包括肺动脉心输出量测量）、在尾动脉进行多次无创血压测量（测量收缩压[SAP]、舒张压[DAP]和平均动脉压[MAP]）以及在外侧趾动脉进行动脉血流的多普勒超声测量。根据之前的检查，30匹马被认为心脏健康。另外30匹马被诊断患有各种心脏病（二尖瓣关闭不全、主动脉瓣关闭不全和心房颤动）。在早晨和晚上测定了18匹健康马匹和18匹患心脏病马匹的血压昼夜变化。在3匹患心房颤动的马匹中，在成功复律前后测定了血压。
在健康马匹中，测得的平均血压如下：收缩压118±21 mmHg，舒张压70±19 mmHg，平均动脉压87±19 mmHg。健康马匹与患心脏病马匹之间未发现显著差异。主动脉瓣关闭不全倾向于导致较高的收缩压（p = 0.05），而与健康马匹相比，心房颤动会降低血压。关于血压的昼夜节律，健康马匹在晚上收缩动脉压略有升高。
高清示波血压计提供了一种直接、间接测定血压的方法，能给出有意义的值。然而，该方法不适合监测心脏病的发展或治疗情况。
