| Abstract |
|
Chronic obstructive pulmonary disease (COPD) has been associated with a high
frequency of various cardiac arrhythmias; and it is not uncommon to find atrial fibrillation (AF) in
COPD patients in practice. The purpose of this study was to investigate the role of reduced lung
function in the prevalence of AF on a base of clinical field. We studied 128 human who presented
exertional dyspnea; except the patients showing low ejection fraction (<40%); valvular heart
disease and ischemic heart disease. They were divided into 65 atrial fibrillation (AF) group and
63 sinus rhythm (control) group. FEV1; FEV1% pred. and FEV1/FVC were significantly lower in
AF group. In echocardiography; left atrial enlargement and hepatic vein congestion were more
frequently observed in AF group; and right ventricular systolic pressure showed higher in AF
group comparing to the control. It is concluded that the reduced values of FEV1; FEV1% and
FEV1/FVC are associated with the prevalence of AF; and further the reduced pulmonary function
might be one of the risk factors in terms of AF. Even though there were no left ventricular
hypertrophy and no remarkable deterioration of ejection fraction (≥40%); we have observed the
hemodynamically significant congestion and atrial enlargement in AF group with the increase of
right ventricular systolic pressure. |
