Clinical Outcome of Patients Who Develop PAF After CABG Surgery

Abstract

This was a retrospective analysis of patients who had CABG surgery at our hospital over a 12-month period to determine the intermediate-term prognosis of those who had developed PAF after their operation before hospital discharge. Of 317 patients who were operated by a single surgical group, 116 (37%) had AF postoperatively of whom 112 had the paroxysmal form. Of these, 36 were treated with class I or III antiarrhythmic drugs and rate control drugs (group 1) and 76 were treated with rate control alone (group 2). Group 3 consisted of 151 randomly selected patients who did not have AF. All patients were reevaluated at 6 weeks to determine their rhythm and clinical status. Only one patient each in groups 1 and 2 was in AF 6 weeks after discharge. There was a trend toward a higher mortality and morbidity in group 2 patients. PAF after coronary surgery appears to be a self-limited disease process. In this cohort of patients, the rate of recurrence of AF after discharge was similar in patients receiving class I or class III antiarrhythmic drugs together with rate control agents compared to those receiving rate control drugs alone.

Atrial Fibrillation at Mid-Term After Bioprosthetic Aortic Valve Replacement

“…Other abbreviations as in Table 1. 26 Elahi et al reported a POAF incidence of 14% in the immediate postoperative period, 2% at 6 weeks and 1% at 1 year postoperatively. 5 These studies, however, collected information retrospectively, and in the Elahi et al study, data on late follow-up were collected via telephone national guidelines encouraging a prescription of antiplatelet therapy only.…”

Inflammation of Atrium After Cardiac Surgery Is Associated With Inhomogeneity of Atrial Conduction and Atrial Fibrillation

“…[1][2][3] Postoperative AF after cardiac surgery can cause a number of complications, including congestive heart failure, stroke, and hemodynamic instability. It is responsible for increased hospital costs and prolonged hospitalization.…”

“…It is responsible for increased hospital costs and prolonged hospitalization. [1][2][3] This tachyarrhythmia usually occurs within 1 week after cardiac surgery and generally resolves over the first 3 weeks after cardiac surgery. Previous studies have shown that the peak incidence of early postoperative AF is on the second postoperative day after CABG.…”

Efeitos da estimulação temporária atrial direita na prevenção da fibrilação atrial no pós-operatório de revascularização do miocárdio com circulação extracorpórea

“…It typically occurs between the first and the fifth day following surgery with frequency peak on the second day [2]. Although it is well tolerated in the majority of the patients [3], AF can result in hemodynamic instability, especially in those patients with left ventricular diastolic dysfunction because they present a reduced tolerance to the loss of atrial contraction [4]. Limiting the use of betablockers and amiodarone [5,6], as a prophylactic pharmacological measurement of postoperative AF, have induced studies regarding prophylactic nonpharmacological measurements.…”
