Blood Platelet structure and functions in hemostasis

What Are Platelet Disorders?

Platelet disorders are conditions that occur when the platelet count in your blood is too high or too low or your platelets do not work properly. Platelets are tiny blood cells that are made in the bone marrow from larger cells. When you are injured, platelets form a plug, called a blood clot, to seal your wound. Blood clots help stop or slow down bleeding.


What Are Pacemakers?

A pacemaker is a small device used to treat some arrhythmias. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. Pacemakers send electrical pulses to help your heart beat at a normal rate and rhythm. Pacemakers can also be used to help your heart chambers beat in sync so your heart can pump blood more efficiently to your body.

Transcatheter Aortic Valve Replacement (TAVR)

Transcatheter Aortic Valve Replacement (TAVR)

Transcatheter aortic valve replacement (TAVR), also known as TAVR or transcatheter aortic valve implantation (TAVI), is a procedure to treat aortic stenosis, a narrowing of the aortic valve. The narrowing blocks the flow of blood to your body and forces your heart to work harder. This causes symptoms such as chest pain and shortness of breath.

Primary Ciliary Dyskinesia

What Is Primary Ciliary Dyskinesia?

Primary ciliary dyskinesia, or PCD, is a rare disease that affects the tiny, hairlike structures (cilia) that line the airways. It affects approximately 1 in every 10,000 to 30,000 people. PCD is an inherited disease. “Inherited” means the disease is passed from parents to children through genes. With PCD, this process is very complex. Researchers are still learning how the disease is inherited and which genes are involved.

What is overweight (obesity)?

Obesity Hypoventilation Syndrome

Obesity hypoventilation syndrome, also known as Pickwickian syndrome, is a breathing disorder that affects some people who have been diagnosed with obesity. Normally, you exhale carbon dioxide, a by-product of breaking down food for energy. Obesity hypoventilation syndrome causes you to have too much carbon dioxide and too little oxygen in your blood.
