ESTIMATION OF VON WILLEBRAND FACTOR IN PATIENTS CARDIAC DISEASES
Insights
Patients with ischemic heart disease (IHD) show significantly elevated levels of von Willebrand factor (VWF). This finding suggests a potential link between VWF and coronary artery disease, warranting further investigation into its diagnostic and management utility.
Area of Science:
- Cardiology
- Biochemistry
- Hematology
Background:
- Ischemic heart disease (IHD), also known as coronary artery disease (CAD), results from narrowed coronary arteries restricting blood flow to the heart muscle.
- Understanding biomarkers associated with CAD is crucial for diagnosis and management.
Purpose of the Study:
- To determine and compare the levels of von Willebrand factor (VWF) in patients with coronary artery disease (CAD) versus healthy individuals.
- To investigate the relationship between VWF levels and other cardiovascular risk factors, including lipid profiles and hypertension, in CAD patients.
Main Methods:
- A cohort of 60 CAD patients and 30 healthy controls was recruited.
- Serum samples were analyzed for lipid profiles (cholesterol, triglyceride, LDL, HDL), human von Willebrand Factor (VWF), and lactate dehydrogenase (LDH).
Main Results:
- Mean VWF levels were significantly higher in IHD patients (81.75±29.75 ng/ml) compared to the control group (26.53±5.12 ng/ml) (P=0.0001).
- IHD patients exhibited elevated cholesterol, triglyceride, and LDL, with lower HDL compared to controls.
- Hypertensive IHD patients showed higher VWF levels (88.76 ng/ml) than non-hypertensive IHD patients (75.76 ng/ml) (P=0.043).
- VWF correlated negatively with LDL and positively with cholesterol, triglyceride, and HDL in IHD patients.
Conclusions:
- Patients with ischemic heart disease exhibit elevated von Willebrand factor levels.
- The findings suggest a potential role for VWF in the pathophysiology of cardiovascular disease.
- Further research is necessary to elucidate the precise relationship between VWF and cardiovascular disease and its clinical applicability.
Abstract:
Ischemic heart disease, also called coronary artery disease (CAD), is the term given to heart problems caused by narrowed heart (coronary) arteries that supply blood to the heart muscle.The study aims to determine the levels of Von Willebrand factor in patients with coronary artery disease.A total of 60 CAD patients and 30 healthy individuals were enrolled in the present study. Blood was withdrawn and serum was separated for measurement of lipid profile, human von Willebrand Factor, and lactate dehydrogenase (LDH).The study demonstrated that the highest mean of VWF was observed among IHD patients (81.75±29.75 ng/ml) and the lowest mean was within the control group (26.53±5.12 ng/ml). The differences were highly significant (P=0.0001). The study showed that the highest means of cholesterol, triglyceride, and LDL and the lowest mean of HDL were detected in IHD patients as compared with the healthy control group. The study showed that the mean of VWF was (88.76 ng/ml) in patients with hypertension which were significantly highest than in non-hypertensive IHD patients (75.76 ng/ml) at P=0.043. The study showed that the highest means of cholesterol, Triglyceride and HDL were detected in hypertensive IHD patients (264.3, 349.1, and 29.24 mg/dl respectively) as compared with non-hypertensive IHD patients group (217.5, 226.1 and 22.02 mg/dl), respectively. The study showed a significant negative correlation between VWF and LDL among IHD patients and showed a positive correlation of VWF with each of cholesterol, triglyceride, and HDL among IHD patients.In conclusion, the findings of the study suggest that patients with ischemic heart disease (IHD) have elevated levels of the von Willebrand factor. More research is needed to fully understand the relationship between VWF and cardiovascular disease and to determine the clinical utility of its measuring in the diagnosis and management of these conditions.
