Insights
Platelet activation marker CD62P is elevated in patients with unstable angina pectoris (UAP) and correlates with coronary artery stenosis severity. This finding highlights CD62P
Area of Science:
- Cardiovascular Medicine
- Hematology
- Biochemistry
Context:
- Coronary heart disease (CHD) involves complex pathophysiological processes including platelet activation.
- Platelet activation is a critical factor in the development and progression of atherosclerotic disease.
- Assessing platelet activation markers can provide insights into disease severity and patient prognosis.
Purpose:
- To investigate the role of platelet alpha-granule membrane protein (CD62P) in patients with coronary heart disease (CHD).
- To determine the relationship between CD62P levels and the severity of coronary artery stenosis.
- To compare CD62P levels across different clinical presentations of CHD (stable angina, unstable angina, acute myocardial infarction) and healthy controls.
Summary:
- The study analyzed CD62P levels in 70 CHD patients (stable angina, unstable angina, acute myocardial infarction) and 20 controls using flow cytometry.
- CD62P positive rates were significantly higher in unstable angina pectoris (UAP) patients compared to stable angina pectoris (SAP) and no-CHD groups.
- Elevated CD62P levels were also observed in patients with multi-vessel coronary artery disease, indicating a correlation with stenosis severity.
Impact:
- The findings suggest that CD62P is a valuable biomarker for platelet activation in CHD, particularly in UAP.
- Elevated CD62P levels are associated with the pathophysiological processes underlying UAP and the extent of coronary artery stenosis.
- This research may contribute to improved diagnostic and prognostic strategies for patients with coronary heart disease.
Objective:
To investigate the role of alpha-granule membrane protein (CD62P), marker of plate activation, in the patients with coronary heart disease (CHD) and to investigate the relationship between the severity of coronary artery stenosis and platelet activation.
Methods:
Peripheral blood samples were collected from 70 patients with CHD, including 28 cases of stable angina pectoris (SAP), 26 cases of unstable angina pectoris (UAP), and 16 cases of acute myocardial infarction (AMI), all of which underwent coronary arteriography, and 20 angiographically normal persons as no-CHD controls. The CD62P level was analyzed by flow cytometry (FCM).
Results:
Coronary arteriography showed positivity in 70 of the 90 CHD patients. The CD62P positive rate of the UAP group was (28.3 +/- 20.1)%, significantly higher than those of the SAP group [(12.8 +/- 13.3)%] and no-CHD group [(9.9 +/- 6.4)%, both P < 0.05]. The CD62P positive rate of the double vessel disease group was (24.0 +/- 17.8)%, not significantly different from that of the three-vessel disease group [(22.6 +/- 20.4)%], but significantly higher than that of the single-vessel disease group [(11.1 +/- 8.5)%] and that of the no-CHD group [(9.9 +/- 6.4)%, both P < 0.05].
Conclusion:
The platelet alpha-granule membrane protein CD62P level is higher in the UAP patients. It is related to the pathophysiological process of UAP and the severity of coronary artery stenosis.
