AF: Atrial Fibrillation Data

In boostmtree: Boosted Multivariate Trees for Longitudinal Data

Atrial Fibrillation Data

Description

Atrial Fibrillation (AF) data from a randomized clinical trial examining the effect of surgical ablation as a treatment for AF in patients with persistent or long-standing persistent AF who required mitral valve surgery. Patients were randomized into two groups: mitral valve surgery with ablation and mitral valve surgery without ablation. Patients assigned to the ablation group were further randomized to one of two procedures: pulmonary vein isolation (PVI) or biatrial maze procedure. All patients were followed weekly over a 12-month period. The primary outcome is the presence or absence of AF, measured as a binary longitudinal response. The dataset includes 228 patients, with a total of 7,949 AF measurements and an average of 35 observations per patient.

Format

A list containing four elements:

1. The 84 patient variables (features).

2. Time points (time).

3. Unique patient identifier (id).

4. Presence or absence of AF (y).
