测定44例冠脉造影者的全血表观粘度和非创伤性左心收缩功能。按冠脉造影结果将受试者分为A、B两组,A组的冠脉主干狭窄>50%,B组冠脉主干狭窄<50%或正常。与B组比较,A组6种切变率的全血表观粘度增高,LVET缩短,PEP延长,PEP/LVET比值增大。全血表观粘度与PEP/LVET比值正相关,说明全血表观粘度是影响左心收缩功能因素之一。
Blood viscosity and non-traumatic left ventricular systolic function were measured in 44 patients with coronary angiography. According to the results of coronary angiography, subjects were divided into A and B groups. The main coronary stenosis in group A was> 50%, and the coronary stenosis in group B was <50% or normal. Compared with group B, the apparent viscosity of whole blood of six kinds of shear rate of Group A increased, LVET shortened, PEP prolonged and PEP / LVET ratio increased. The apparent viscosity of whole blood was positively correlated with the ratio of PEP / LVET, indicating that the apparent viscosity of whole blood is one of the factors affecting left ventricular systolic function.
