Summaries for Orthostatic Intolerance

MedlinePlus : 41 mitral valve prolapse (mvp) occurs when one of your heart's valves doesn't work properly. the flaps of the valve are "floppy" and don't close tightly. most people who have the condition are born with it. it also tends to run in families. most of the time, mvp doesn't cause any problems. rarely, blood can leak the wrong way through the floppy valve. this can cause palpitations (feelings that your heart is skipping a beat, fluttering, or beating too hard or too fast) shortness of breath cough fatigue, dizziness, or anxiety migraine headaches chest discomfort most people who have mitral valve prolapse (mvp) don't need treatment because they don't have symptoms and complications. if you need treatment for mvp, medicines can help relieve symptoms or prevent complications. very few people will need surgery to repair or replace the mitral valve. mvp puts you at risk for infective endocarditis, a kind of heart infection. to prevent it, doctors used to prescribe antibiotics before dental work or certain surgeries. now, only people at high risk of endocarditis need the antibiotics. nih: national heart, lung, and blood institute

MalaCards based summary : Orthostatic Intolerance, also known as mitral valve prolapse, is related to mitral valve prolapse, myxomatous 2 and mitral valve prolapse, myxomatous 3, and has symptoms including orthostatic tachycardia, angina pectoris and chest pain. An important gene associated with Orthostatic Intolerance is SLC6A2 (Solute Carrier Family 6 Member 2), and among its related pathways/superpathways are Peptide ligand-binding receptors and NFAT and Cardiac Hypertrophy. The drugs Metoprolol and Propranolol have been mentioned in the context of this disorder. Affiliated tissues include heart, lung and testes, and related phenotypes are cardiovascular system and behavior/neurological

UniProtKB/Swiss-Prot : 66 Orthostatic intolerance: Syndrome characterized by lightheadedness, fatigue, altered mentation and syncope. It is associated with postural tachycardia. Plasma norepinephrine concentration is abnormally high.

Disease Ontology : 12 A mitral valve disease where one or both of the cusps of the mitral valve bulge or collapse backward in the left atrium during systole.

Wikipedia : 71 Orthostatic intolerance (OI) is the development of symptoms when standing upright which are relieved... more...
