Abstract

Introduction Coexistence of atrial fibrillation (AF) in patients with heart failure (HF) is a common phenomenon associated with poor prognosis. Therefore, this study was designed with an aim to estimate the different risk factors of atrial fibrillation (AF) in patients with HF. Methods In this study, patients of either gender, 18 to 80 years of age, and with echocardiographic confirmation of HF presenting at the adult cardiology department of the National Institute of Cardiovascular Diseases (NICVD), Karachi, Pakistan were consecutively included. Patients diagnosed with chronic obstructive airway diseases, pneumonia, or pericarditis, and patients diagnosed with existing AF were excluded from the study. Data regarding demographic and clinical risk factors of AF were obtained using a structural proforma. Results Out of 150 patients, 59.3% (89) were females, and the mean age was 50 ± 16 years. A majority of the patients, 55.3% (83), had a history of rheumatic heart diseases (RHD) and 22.7 (34) percent had a history of transient ischemic attack (TIA) or cerebrovascular accident (CVA). On echocardiography, 28.0% (42) of the patients had right ventricular (RV) dysfunction, and the clot was seen in 28.0% (42) of the patients. Mitral s...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.
