Abstract

Atrial fibrillation (AF) is the most common cardiac rhythm disorder in clinical practice, with a growing prevalence in recent decades. Through the use of thromboembolic risk scores it is possible to adjust thromboprophylaxis to individual risk. The aim of this study was to evaluate the conformity of antithrombotic therapy prescribed at hospital discharge with the guidelines in patients with AF and its influence on long-term morbidity and mortality. We performed a retrospective analysis, based on medical records and phone interview, of consecutive patients admitted to an internal medicine department over a one-year period with a diagnosis of AF or atrial flutter--ICD-9-CM 427.31/32. We determined individual thromboembolic risk in accordance with the ACC/AHA/ESC risk categories, and assessed conformity of antithrombotic therapy with the guidelines. Independent predictors of long-term (378 +/- 241 days) mortality and mortality or readmission were identified by multivariate analysis. The study population consisted of 174 patients with a diagnosis of AF, 59.8% (104) female, mean age 77 +/- 10 years. Hypertension (65.7%) and heart failure (61.3%) were the most prevalent comorbidities. Most patients (82.7%) were stratified as high thr...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
