Atrial Fibrillation:A Big Problem Getting Bigger

Atrial Fibrillation,or AFib,is a heart rhythm disorder which is sweeping through the growing ranks of the elderly.That's understandable,since age is one of the main predispositions for the disease.From a current patient population of about 5 million,the number of AFib patients is expected to triple by 2050.Many of them are already dealing with other chronic diseases-especially cardiovascular ones.
In AFib,the two upper chambers of the heart,or atria,beat erratically and out of sync with the two lower chambers,or ventricles.This can result in a number of symptoms such as heart palpitations;lightheadedness;fatigue;shortness of breath;disorientation;and even chest pain.During AFib,an electrical overload in the heart results in an irregular,rapid heartbeat.These erratic signals may be caused by factors such as damage to the heart's structure from hypertension;heart valve disease;heart attacks;congenital heart defects;metabolic disorders;lung disease;stimulants;heart surgery;viral infection;and sleep apnea.Age,alcoholism and heredity may predispose a patient for AFib.
AFib can lead to stroke and heart failure.Left untreated,it tends to become more severe and less amenable to treatment as time goes on.Recent studies point to a link between AFib and dementia.That stands to reason,since AFib can easily hinder blood flow to the brain.
AFib is typically diagnosed by means of various monitors attached to the body with electrodes.Treatment ranges from medication to electric shock therapy,as well as various catheter procedures.Blood thinners such as Warfarin and its branded form Coumadin,plus the newer Pradaxa are frequently prescribed to lesson the considerable risk of blood clot formation and stroke from AFib.
If your heart seems to be acting up,it's best to consult with your doctor about it.It could be AFib or another dangerous cardiac arrhythmia.
German pharmaceutical company Boehringer Ingelheim,which is privately held,makes Pradaxa,while Coumadin is a product of Bristol-Myers Squibb.
