Risk Factor Characterization of Ischemic Stroke Subtypes Among West Africans.

Background And Purpose: To identify the qualitative and quantitative contributions of conventional risk factors for occurrence of ischemic stroke and its key pathophysiologic subtypes among West Africans.

Methods: The SIREN (Stroke Investigative Research and Educational Network) is a multicenter, case-control study involving 15 sites in Ghana and Nigeria. Cases include adults aged ≥18 years with ischemic stroke who were etiologically subtyped using the A-S-C-O-D classification into atherosclerosis, small-vessel occlusion, cardiac pathology, other causes, and dissection.

Initial outcome following invasive cardiac electrophysiologic studies and radiofrequency ablation of atrial fibrillation.

Background: Cardiac electrophysiologic study and radiofrequency ablation (RFA) have become an established mode of treatment for patients with refractory arrhythmias. These procedures are carried out regularly at the cardiac catheterization laboratory of Madras Medical Mission India.

Objective: The purpose of this study was to evaluate our experience with cardiac electrophysiologic studies (EPS) and RFA catheter of atrial fibrillation (AF).

Cardiovascular risk factors in adult staff of Federal Medical Centre, Umuahia: a comparison with other Nigerian studies.

Changing lifestyle, driven by socio-economic trends, is changing the cardiovascular risk and disease profile in developing countries. We studied the cardiovascular risk factors of Federal Medical Centre, Umuahia hospital staff between 40 and 60 years. 297 members of hospital staff were consecutively recruited in October 2010.
