Abstract

Over the next decades, the prevalence of atrial fibrillation (AF) is estimated to double. Our aim was to investigate the causes of the long-term mortality in relation to the diagnosis of atrial fibrillation (AF) and chronic coronary syndrome (CCS). The analysed population consisted of 7367 consecutive patients referred for elective coronary angiography enrolled in a large single-centre retrospective registry, out of whom 1484 had AF and 2881 were diagnosed with obstructive CCS. During follow-up (median = 2029 days), 1201 patients died. The highest all-cause death was seen in AF(+)/CCS(+) [194/527; 36.8%], followed by AF(+)/CCS(-) [210/957; 21.9%], AF(-)/CCS(+) [(459/2354; 19.5%)] subgroups. AF ([HR]<sub>AC</sub> = 1.48, 95%CI, 1.09-2.01; HR<sub>CV</sub> = 1.34, 95%CI, 1.07-1.68) and obstructive CCS (HR<sub>AC</sub> = 1.90, 95%CI, 1.56-2.31; HR<sub>CV</sub> = 2.27, 95%CI, 1.94-2.65) together with age, male gender, heart failure, obstructive pulmonary disease, diabetes were predictors of both all-cause and CV mortality. The main findings are as follow among patients referred for elective coronary angiography, both AF and obstructive CCS are strong and independent predictors of the long-term mortality. Mortality of AF without CCS was at least as high as non-AF patients with CCS. CV deaths were more frequent than non-CV deaths in AF patients with CCS compared to those with either AF or CCS alone.
