Plasma Lp(a) and t-PA-PAI-1 complex levels in coronary heart disease
1Department of Biochemistry, Istanbul University, Cerrahpaşa Medical Faculty, Turkey.
Insights
Elevated serum lipoprotein(a) (Lp(a)) and tissue plasminogen activator-plasminogen activator inhibitor-1 (t-PA-PAI-1) complex levels are significantly higher in coronary heart disease (CHD) patients. These findings suggest their role in the development of coronary atherosclerosis.
Area of Science:
- Cardiovascular Medicine
- Biochemistry
Background:
- Coronary heart disease (CHD) is a leading cause of mortality worldwide.
- Lipid profiles and specific biomarkers are crucial for assessing cardiovascular risk.
- Understanding the role of lipoprotein(a) (Lp(a)) and the t-PA-PAI-1 complex in CHD pathogenesis is vital.
Purpose of the Study:
- To investigate serum Lp(a) and plasma t-PA-PAI-1 complex levels in patients with coronary heart disease (CHD).
- To compare these levels with those in a control group.
- To explore the potential role of these markers in the pathogenesis of coronary atherosclerosis.
Main Methods:
- Serum samples were collected from patients diagnosed with CHD and a control group.
- Levels of serum Lp(a) and plasma t-PA-PAI-1 complex were measured.
- Serum lipid profiles including total cholesterol, triglyceride, LDL, VLDL, and HDL cholesterol were analyzed.
Main Results:
- Patients with CHD exhibited significantly higher serum Lp(a) and plasma t-PA-PAI-1 complex levels compared to the control group (p < 0.001).
- Significant differences were observed in serum total cholesterol, triglyceride, LDL, and VLDL cholesterol levels (p < 0.001) and HDL cholesterol levels (p < 0.01) between the patient and control groups.
- Elevated Lp(a) and t-PA-PAI-1 complex levels were strongly associated with the presence of CHD.
Conclusions:
- Elevated serum Lp(a) and plasma t-PA-PAI-1 complex levels are significantly associated with coronary heart disease.
- These biomarkers may play a crucial role in the development and progression of coronary atherosclerosis.
- Further research is warranted to explore therapeutic strategies targeting these markers for CHD prevention and management.
Abstract:
In this study we investigated serum Lp(a) and plasma t-PA-PAI-1 complex levels in patients with coronary heart disease (CHD). Serum total cholesterol, triglyceride, LDL and VDL cholesterol levels (p < 0.001) and HDL cholesterol levels (p < 0.01) in patients group were found to be significantly different from those in control group. The mean Lp(a) and t-PA-PAI-1 complex levels in patients with coronary heart disease were significantly higher as compared to control group (p < 0.001). This data indicate that the elevated levels of serum Lp(a) and plasma t-PA-PAI-1 complex may play an important role in the pathogenesis of coronary atherosclerosis.
