Correlation between the Levels of Different Microparticles in Peripheral Blood and the Occurrence of Coronary Heart Disease and Blood Stasis Syndrome
To explore the diagnostic value of the absolute number of peripheral blood microparticles (MP) of different sizes for coronary heart disease (CHD) and blood stasis (BS) syndrome.
Methods
2
A total of 120 CHD patients were included. Fifty-five cases were diagnosed as having BS syndrome according to the syndrome differentiation standard, while 65 cases were formed into non-BS group. Another 31 healthy volunteers were included as healthy group. Human peripheral blood particles were separated by gradient centrifugation, and the positions of large and small microparticles were delineated on the flow cytometer by 0.46 μm and 1.0 μm microspheres. Annexin V+ (AV+) was used to determine particle. The number of large and small microparticles was presented in absolute count. Univariate analysis and Logistic multivariate regression analysis were performed, using large and small microparticles as independent variables, and CHD and CHD-blood stasis syndrome as dependent variables. The receiver operating characteristic (ROC) curves were drawn to evaluate the diagnosis performance of large and small microparticles for CHD.
Results
2
The absolute numbers of large microparticles and small microparticles in peripheral blood of CHD patients were significantly higher in BS and non-BS group than healthy group (
P
<0.05 or
P
<0.01), and the BS-group had higher absolute number than non-BS group (
P
<0.05 or
P
<0.01). Univariate analysis showed that large microparticles (
r
=0.291,
P
=0.001) and small microparticles (
r
=0.191,
P
=0.036) were associated with the occurrence of BS syndrome in CHD. Logistic multivariate regression analysis showed that large microparticles was associated with the occurrence of CHD (regression coefficient: 0.008,
P
<0.05) and BS syndrome of CHD (regression coefficient: 0.003,
P
<0.05); small microparticles was associated with the occurrence of CHD (regression coefficient: 0.006,
P
= 0.039) and BS syndrome of CHD (regression coefficient: 0.004,
P
<0.05). ROC analysis indicated that the area under the curve (AUC) value of large microparticles was 0.777 (95%
CI
: 0.702-0.852,
P
=0.001), and that of small microparticles was 0.676 (95%
CI
: 0.576-0.776,
P
= 0.003).
Conclusion
2
The levels of large microparticles and small microparticles in peripheral blood are related to the occurrence of CHD and BS syndrome of CHD, and the absolute number of large microparticles has certain diagnostic value for BS syndrome of CHD.
