[The coagulation picture and plasma clearance capacity in atherosclerotic diabetics]
Insights
Atherosclerotic diabetes is linked to clotting and lipid issues. This study explores platelet and lipoprotein interactions, finding hyperaggregability in 60% of patients, suggesting a key role in atherosclerosis.
Area of Science:
- Cardiovascular Research
- Metabolic Disorders
- Hematology
Context:
- Atherosclerotic diabetes presents complex interactions between plasma, coagulation, platelets, and lipids.
- The disease is associated with imbalances in clotting and fibrinolytic systems, favoring thrombogenic factors or reduced inhibitor activity.
Purpose:
- To elucidate the intricate relationships between plasma factors, coagulation, platelets, and lipids in atherosclerotic diabetes.
- To review the roles of lipids, fibrinolysis activators/inhibitors, and platelets in thrombophilia and atherosclerosis pathogenesis.
Summary:
- Literature review and clinical observations highlight thrombophilia in atherosclerotic diabetes, linked to impaired fibrinolysis and enhanced coagulation.
- Platelet hyperaggregability (60% of 30 cases) and altered lipoproteinlipase activity (depressed in 24 of 48 cases) are significant findings.
- Insulin's interaction with lipoproteinlipase and plasma clarifying power are discussed in relation to disease mechanisms.
Impact:
- Provides insights into the pathogenesis of atherosclerosis in diabetic patients.
- Highlights the critical role of platelet function and lipid metabolism in the thrombotic complications of diabetes.
- Suggests potential targets for therapeutic interventions aimed at reducing cardiovascular risk in atherosclerotic diabetes.
Abstract:
An attempt is made to set out the complex question of the relations between plasma and wall factors in coagulation, platelets and lipids in atheroscderotic diabetes. The literature data show that this disease is associated the clotting and fibrinolytic systems as a result of the prevalence of thrombogenic factors and/or poor inhibitor activity. A survey is made of fibrinolysis activators and inhibitors, and of the part played by lipids in the aetiopathogenesis of thrombophilia, though the mechanisms responsible have not yet been fully established. Reference is made to De Gaetano's exposition of Walsh's views concerning the rôle of platelets in clotting. An assessment is made of the relations between platelets and lipoproteins, and hence of the importance of platelets in the pathogenesis of atherosclerosis. Reference is made to a series of atherosclerotic diabetics. Hyperaggregability was noted in 60% of 30 cases. The experimental results obtained by Bierman et al. on the relation between insulin and lipoproteinlipase and the interference of insulin with PHLA are presented in an explanation of the clarifying power of plasma in this disease. Lastly, an account is given of lipoproteinlipase values observed in a personal series of 48 cases employing a radioimmunological technique. Baselines were depressed in 24 subjects.
