A thrombotic tendency in patients with infective endocarditis
Japanese Circulation Journal
|May 1, 1982
Summary
Infective endocarditis (IE) cases show a thrombotic tendency due to platelet changes and mild hypercoagulability. This occurs without accelerated fibrinolysis, indicating a pro-thrombotic state in IE patients.
Area of Science:
- Hematology
- Cardiology
- Infectious Diseases
Background:
- Infective endocarditis (IE) is a serious infection affecting heart valves.
- Understanding the thrombotic tendency in IE is crucial for patient management.
Purpose of the Study:
- To evaluate the thrombotic tendency in infective endocarditis.
- To investigate changes in platelets and the coagulo-fibrinolysis system in IE.
Main Methods:
- Assessed platelet activation using adenosine diphosphate and collagen.
- Measured plasma beta-thromboglobulin levels to detect platelet aggregation.
- Evaluated coagulation status by measuring plasma antithrombin III and alpha 2-plasmin inhibitor levels.
Main Results:
- Platelets showed activated responses, indicating thrombi formation.
- Elevated plasma beta-thromboglobulin levels confirmed platelet aggregation.
- A mild hypercoagulable state was observed, characterized by low antithrombin III and normal alpha 2-plasmin inhibitor levels.
- Fibrinolysis was not accelerated in the studied IE cases.
Conclusions:
- A clear thrombotic tendency exists in infective endocarditis.
- This tendency is driven by qualitative platelet changes and mild hypercoagulability.
- The findings suggest a pro-thrombotic state in IE without compensatory increases in fibrinolysis.
