They also have an increased risk for thromboembolism .
Comparing with age-matched controls , the relative risk for stroke is increased 2- to 7-fold in patients with nonrheumatic atrial fibrillation ( 3 , 8 , 13 ) , and the absolute risk for stroke is between 1 % and 5 % per year , depending on clinical characteristics ( 3 , 12 , 14 - 16 ) .

Data Synthesis Does Aggressive Rhythm Control Improve Mortality and Morbidity Compared with Rate Control ?
Atrial fibrillation is the most common type of arrhythmia in adults , accounting for about one third of hospitalizations for arrhythmia ( 1 ) .
The prevalence increases from less than 1 % in persons younger than 60 years of age to more than 8 % in those older than 80 years of age ( 2 - 6 ) .
The incidence ranges from 0.2 % per year for men 30 to 39 years of age to 2.3 % per year in men 80 to 89 years of age ( 7 , 8) .
The age-adjusted incidence for women is about half that of men ( 9 ) .
The cardiac conditions most commonly associated with atrial fibrillation are rheumatic mitral valve disease , coronary artery disease , congestive heart failure , and hypertension ( 8 , 10 ) .
Noncardiac causes include hyperthyroidism , hypoxic conditions , surgery , and alcohol intoxication .
A predisposing condition exists in more than 90 % of cases ( 5 , 11 , 12 ) ; the remaining cases have what is called lone atrial fibrillation .
Patients with atrial fibrillation frequently have symptoms of hemodynamic compromise , ranging from irregular palpitations to the more insidious feeling of malaise .
Little is known about the direct effects of antiarrhythmic therapy and rate-control therapy on quality of life .
The American College of Cardiology/American Heart Association/European Society of Cardiology Task Force on Clinical Guidelines for the Management of Atrial Fibrillation classified atrial fibrillation into 4 types ( 20 ) : first detected episode , paroxysmal ( terminates spontaneously ) , persistent ( electrical or pharmacologic termination necessary ) , and permanent ( resistant to electrical or pharmacologic conversion or accepted by the physician ) .
The purpose of this review was to summarize the evidence that was available during formulation of the guidelines developed by the American College of Physicians ( ACP ) and the American Academy of Family Physicians ( AAFP ) for management of adult patients with nonpostoperative atrial fibrillation .
Although the relative benefits and risks of rate versus rhythm control are of paramount importance in the management of atrial fibrillation , studies directly addressed this issue only recently .
The effect of stroke and stroke prophylaxis with aspirin or warfarin on quality of life.
BACKGROUND Because most strokes cause neurological impairment rather than death , stroke prophylaxis may improve quality of life more than length of life . Thus , an underst and ing of how stroke and stroke prophylaxis affect quality of life is central to clinical decision making for many patients . METHODS We elicited quality -of-life estimates , known as utilities , for 3 degrees of severity of anticipated stroke-mild , moderate , and major- and for stroke prophylaxis with either warfarin sodium or aspirin therapy . We used the time tradeoff and st and ard gamble methods to elicit these utilities from 83 patients who had atrial fibrillation . RESULTS Seventy patients completed the interview successfully . Their utilities for stroke ranged from worse than death ( < 0 ) to as good as current health ( 1.0 ) . The median utilities for mild , moderate , and major stroke were 0.94 , 0.07 , and 0.0 , respectively . Although the median utilities decreased with increasing severity of stroke ( P < .001 ) , there was high interpatient variability within each degree of stroke severity . For example , 7 subjects ( 10 % ) rated a major stroke above 0.5 , while 58 subjects ( 83 % ) rated it as equal to or worse than death . In contrast to the stroke utilities , the median utilities for warfarin and aspirin therapy were high-0.997 and 1.0 , respectively . However , the interpatient variability for warfarin therapy was also important : 11 patients ( 16 % ) with atrial fibrillation rated the utility of warfarin therapy so low that their quality -adjusted life expectancy would be greater with aspirin . CONCLUSION Patients ' utilities for stroke prophylaxis and anticipated stroke vary substantially . Many patients view the quality of life with major stroke as tantamount to or worse than death . These findings highlight the relevance of incorporating patient preferences when choosing stroke prophylaxis
They also have an increased risk for thromboembolism .
Comparing with age-matched controls , the relative risk for stroke is increased 2- to 7-fold in patients with nonrheumatic atrial fibrillation ( 3 , 8 , 13 ) , and the absolute risk for stroke is between 1 % and 5 % per year , depending on clinical characteristics ( 3 , 12 , 14 - 16 ) .
