New-onset atrial fibrillation after an acute coronary syndrome: experience of the cardiology department at Mohammed VI University Hospital in Marrakech (a study of 155 cases)

To determine the frequency of atrial fibrillation (AF) in patients admitted for acute coronary syndrome (ACS) and to identify factors that may predict it, we conducted a retrospective, descriptive, and comparative observational study involving patients admitted for ACS who had no prior history of AF. Our study included 155 patients hospitalized for ACS. We found that 9.6% of these patients developed new-onset AF. We identified several predictors for new-onset AF: being elderly, having chronic kidney disease, a history of stroke and having high uric acid level. The occurrence of new-onset AF in patients with ACS was found to be 9.6%. Given the strong association between ACS and AF, routine screening for AF in these patients is advisable.
