Hemodynamic characteristics and exercise tolerance in patients with atrial fibrillation during mechanotherapy after ischemic stroke

Aim. To study hemodynamic characteristics and exercise tolerance during mechanotherapy in patients after ischemic stroke (IS). Material and methods. The study included 80 patients after IS. Mean age was 61,0±10,5 years, while the duration of ischemic stroke — 13,1±8,5 months. Rehabilitation routing score was 4. Fifty patients have sinus rhythm, while 10 — paroxysmal atrial fibrillation (AF), and 20 — permanent AF. According to Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification, there were 21 patients with atherothrombotic stroke, 30 patients with cardioembolic stroke, 29 patients with stroke of unknown etiology. The following examinations were performed: echocardiography with assessment of left ventricular (LV) global longitudinal strain (GLS), blood test with assessment of N-terminal probrain natriuretic peptide (NT-proBNP). Mechanotherapy was performed daily on a Reck MOTOmed muvi simulator (Germany), with hemodynamic assessment during training on days 1 and 12. Results. Patients with AF, compared with patients in sinus rhythm, were significantly older (65,7±7,2 vs, 58,0±11,2 years; p=0,002) and had higher NTproBNP levels (192,1 [30,3; 282,2] vs, 15,7 [0; 16,2] pg/ml; p
