Identify the vitamin K—dependent coagulation factors. Provide examples of genetic disorders that lead to bleeding. Describe the process of fibrinolysis. This is the principle cause of angina, heart attacks and stroke, which together c ause high levels of suffering and death. Thrombosis is frequently precipitated by the presence in arteries of atherosclerotic lesions which may rupture causing the release of pro-thrombotic molecules and exposure of the blood vessel wall.
The suppression of platelet function with pharmacological agents is used successfully in many patients to prevent the occurrence of thrombosis. Current drugs, however, are ineffective in many patients and are associated with substantial side effects that include bleeding.
The main difference between Haemostasis and Thrombosis is that thrombosis is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system whereas haemostasis is a natural clotting mechanism which takes place to prevent excessive bleeding following an injury. What is Haemostasis? What is Thrombosis? Difference Between Haemostasis and Thrombosis. Haemostasis is defined as the normal physiological response which prevents the body from experiencing a significant blood loss following a vascular injury.
The fundamental mechanism of haemostasis is based on an intricate series of events which consists of the actions of platelets, other blood cells like tissue factor [TF]-bearing cells and specific blood proteins called coagulation factors.
On the very moment a vascular injury occurs following trauma, the triggered physiological haemostasis comes into action and begins a series of processes discussed below. Just after the injury, the blood vessels will start constricting in order to reduce the blood flow to the affected area.
Then, the circulating platelets will rush to the trauma site and get adhered to the vessel wall or endothelium,and aggregate in clumps. This helps us to obtain the best tests and discover the cause of the bleeding. Hemophilia, the most common coagulation condition that may cause unusual bleeding, is an example of a congenital condition where an important factor needed to make a blood clot is reduced or missing.
Individuals with these conditions, either hereditary or acquired, have a tendency to bleed even without injury. In many cases, we are able to treat these patients by giving back what is missing through infusions. We provide infusions to help children live a life that results in less bleeding episodes, safe involvement in activities, and overall improved quality of life.
