Summary
Altered hemorheological parameters, including fibrinogen and viscosity, are linked to the severity of coronary artery disease (CAD). These blood flow properties may contribute to the development of ischemic heart disease (IHD).
Area of Science:
- Cardiovascular Medicine
- Hematology
Background:
- Hemorheological parameters are established risk factors for ischemic heart disease (IHD).
- Understanding the relationship between hemorheology and coronary artery disease (CAD) severity is crucial for risk stratification.
Purpose of the Study:
- To investigate the association between hemorheological parameters and the severity of coronary artery disease (CAD).
Main Methods:
- Analysis of hemorheological parameters (hematocrit, fibrinogen, plasma viscosity (PV), whole blood viscosity (WBV), circulatory index (CRI)) in 109 CAD patients and 59 controls.
- Classification of patients into groups based on coronary angiogram findings: no significant CAD, single-vessel disease, and multi-vessel disease.
Main Results:
- IHD patients exhibited significantly higher hemorheological parameters compared to controls.
- Fibrinogen and PV were elevated in single and multi-vessel disease groups versus the no-CAD group.
- Hematocrit and WBV increased significantly with disease severity (multi-vessel disease).
- Circulatory index (CRI) was reduced in IHD patients, particularly in the multi-vessel disease group.
Conclusions:
- Hemorheological alterations are associated with the severity of coronary artery disease.
- These parameters may play a significant role in the pathogenesis and progression of CAD.
