Prognosis of congestive heart failure after prior myocardial infarction in older persons with atrial fibrillation versus sinus rhythm.
In a prospective study of 651 older persons with congestive heart failure after prior myocardial infarction, persons with atrial fibrillation had a significantly higher mortality than those with sinus rhythm if they had an abnormal (p = 0.005) or normal (p = 0.0001) left ventricular ejection fraction. The Cox regression model showed that significant independent risk factors for total mortality were age (risk ratio 1.03 for an increment of 1 year of age), hypertension (risk ratio 1.2), diabetes mellitus (risk ratio 1.4), abnormal left ventricular ejection fraction (risk ratio 2.1), and atrial fibrillation (risk ratio 1.5).
