Quality of life in atrial fibrillation.
In patients with atrial fibrillation (AF), the restoration and maintenance of sinus rhythm is the primary therapeutic goal. Once sinus rhythm is maintained, physiological rate control is restored, and left ventricular ejection fraction, cardiac output, and exercise capacity are increased. This improved cardiovascular performance thereby enhances the patient's ability to perform the functions of normal daily life. The primary intervention for maintaining sinus rhythm after restoration is the use of anti-arrhythmic agents. Although physicians mostly use class 1A anti-arrhythmic drugs, these oral agents only maintain sinus rhythm in a limited number of cases and are accompanied by considerable side effects. Therefore, more effective tools are needed. Effective treatment for AF is based on the above objective criteria, but subjective criteria such as the quality of life are growing in importance. To address these quality-of-life issues, we have initiated a prospective study in which patients are assigned to one of two groups: those with paroxysmal AF who are candidates for permanent implantable atrial defibrillators and those with chronic or paroxysmal AF who are not candidates for atrial defibrillators. Specifically designed questionnaires and various standardized and validated instruments are used to measure quality of life. The questionnaires cover social demographic data, including age, education, occupation level, driving behavior, return to work, and sexual activity. Quality of life is a multidimensional construct, and thus its definition must consider the many factors mentioned above. In the final analysis, therefore, both objective and subjective criteria are necessary to define appropriate treatment of AF.
