Acute coronary syndromes and atrial fibrillation

Acute coronary syndromes and atrial fibrillation.

Impact of atrial fibrillation type during acute coronary syndromes: Clinical features and prognosis.

INTRODUCTION Atrial fibrillation (AF) is widely recognized as an adverse prognostic factor during acute myocardial infarction, although the impact of AF type - new-onset (nAF) or pre-existing (pAF) - is still controversial. OBJECTIVES To identify the clinical differences and prognosis of nAF and pAF during acute coronary syndromes (ACS). METHODS We performed a retrospective observational co...

Comparison of outcomes of patients with acute coronary syndromes with and without atrial fibrillation.

Preexisting or new-onset atrial fibrillation (AF) commonly occurs in patients with an acute coronary syndrome (ACS). However, it is currently unknown if previous or new-onset AF confers different risks in these patients. To determine the prognostic significance of new-onset and previous AF in patients with ACS, we evaluated all patients with ACS enrolled in the multinational Global Registry of ...

Indirect and direct costs of acute coronary syndromes with comorbid atrial fibrillation, heart failure, or both

BACKGROUND The objective of this study was to determine the direct and indirect costs of acute coronary syndromes (ACS) alone and with common cardiovascular comorbidities. METHODS A retrospective analysis was conducted using the Medical Expenditure Panel Survey from 1998 to 2009. Four mutually exclusive cohorts were evaluated: ACS only, ACS with atrial fibrillation (AF), ACS with heart failur...

Warfarin use and outcomes in patients with atrial fibrillation complicating acute coronary syndromes.

BACKGROUND We examined warfarin use at discharge (according to Congestive heart failure, Hypertension, Age>75 years, Diabetes, Prior Stroke/transient ischemic attack score and bleeding risk) and its association with 6-month death or myocardial infarction in patients with post-acute coronary syndrome atrial fibrillation. METHODS Of the 23,208 patients enrolled in the Platelet IIb/IIIa in Unsta...
