People with anxiety disorders have a higher risk of developing and dying of heart disease. Scientists at the Clinic and Policlinic for Psychotherapy and the Institute of Experimental Hematology and Transfusion Medicine may have discovered why this might be true.
Lead scientists, Franziska Geiser and Ursula Harbrecht studied the effects of anxiety on blood coagulation (thickening of the blood or clotting).
For those suffering from panic disorder or anxiety attacks, utter fear are all too well known. Some of the common symptoms of an anxiety attack include heart palpitations, sweating, and tremors. Although physical symptoms such as these are common in panic or anxiety attacks, the symptoms normally disappear once the anxiety attack is over. But does the fear actually cause physical symptoms which can be dangerous?
Our bodies have two distinct functions relating to blood clotting. The first, coagulation, thickens the blood to help form a plug over injuries to reduce...
Blood clots are the clumps that form when blood hardens from liquid to solid. A blood clot that forms in a blood vessel or in the heart and stays put is called a thrombus. A blood clot that moves to another part of the body is called an embolus and the situation is called an embolism. Blood clots can attach to blood vessels and partially or completely block the flow of blood. When a vein swells because of a blood clot, it's called phlebitis. This blockage stops the usual amount of blood and oxygen from reaching the tissues in that location, which can damage the tissue. Blood clots also can increase your risk of having a stroke. A stroke happens when a blood clot blocks an artery or a blood vessel breaks, interrupting blood flow to the brain.
Symptoms of blood clots include:
warmth and tenderness over the vein
pain or swelling
Certain breast cancer treatments can increase your risk for blood clots. They are:
Avastin (chemical name: bevacizumab), a targeted therapy
Blood clots are clumps that occur when blood hardens from a liquid to a solid.
A blood clot that forms inside a blood vessel or within the heart and stays there is called a thrombus. A thrombus that breaks loose and travels from one location in the body to another is called an embolus. The related medical disorder is called an embolism. For example, an embolus that gets stuck in the lungs is called a pulmonary embolism.
Sometimes other materials can act like an embolus and block blood flow, including:
A piece of atherosclerotic plaque
Small pieces of tumor
Atheroembolic renal disease
Deep venous thrombosis
Renal vein thrombosis
