Introduction
The development of cardiogenic shock (CS) is associated with worse prognosis, and can produce several hemodynamic manifestations. Then, is not surprised the manifestation of new-onset atrial fibrillation (AF) in these patients.
Purpose
Evaluate the impact of cardiovascular previous history, clinical signs and diagnosis procedures at admission as predictors of new-onset of AF in CS.
Methods
Single-centre retrospective study, engaging patients hospitalized for CS between 1/01/2014-30/10/2018. 222 patients with CS are included, 40 of them presented new onset of AF. Chi-square test, T-student test and Mann-Whitney U test were used to compare categorical and continuous variables. Multiple linear regression analysis was performed to evaluate predictors of new-onset AF in CS patients.
Results
CS patients without AF had a mean age of 61.08 ± 13.77 years old, on the other hand new-onset of AF patients in the setting of CS had a mean age of 67.02 ± 14.21 years old (p = 0.016). Nevertheless, no differences between the two groups was detected regarding the sex cardiovascular history (namely arterial hypertension, diabetes, dyslipidemia, obesity, smoker status, alcohol intake, previous acute coronary syndrome, history of angina, previous cardiomyopathy), neoplasia history, cardiac arrest during the CS, clinical signs at admission (like heart rate, blood pressure, respiratory rate), blood results (hemoglobin, leukocytes, troponin, creatinine, C-Reactive protein), left ventricular ejection fraction and the culprit lesion. New-onset of AF in CS patient had not impact in mortality rates. Multiple logistic regression reveals that only age was a predictor of new onset of AF in CS patients (odds ratio 1.032, confident interval 1.004-1.060, p = 0.024).
Conclusions
Age was the best predictor of new-onset AF in CS patients. The presence of this arrhythmia can have a hemodynamic impact, however, seems not influenced the final outcome.
