Structural and Fucntional Parameters of the Cardiovascular System During Atrial Fibrillation in Patients After Stroke

Abstract

The aim: To evaluate the structural and functional parameters of the cardiovascular system during atrial fibrillation (AF) in patients after a stroke. Materials and methods: In the main group, we selected 28 patients with non-valvular AF who had previously suffered an ischemic stroke (IS). The comparison group (30 people) included patients with AF without a stroke, comparable in age and gender. Results: As a result of the study, we discovered an increase in the risk of stroke with an increase in the thickness of the intima-media complex>0.9mm. The thickness of the interventricular septum was 1.19 (1.1; 1.25) in the group of patients with IS, and in the group of patients without IS – 1.09 (1.0; 1.19) cm (p = 0.019), the thickness of the LV posterior wall is greater in the main group 1.14 (1.05; 1.24) and 1.09 (1.01; 1.18) cm in the comparison group (p = 0.038). The myocardial mass index is 123.3 in the main group and 107.4 g/m2 in the comparison group (p = 0.41), which indicates left ventricle (LV) hypertrophy in the main group. Conclusions: thus, during AF in stroke patients, changes in the following structural and functional parameters of the cardiovascular system were discovered: an increase in the thickness of the interventricular septum, thickness of the posterior wall of the LV, and in the thickness of the intima-media complex.

Stroke–heart syndrome: current progress and future outlook

“…Consistent with the above-mentioned results, the incidence of AF detected after stroke (AFDAS) was higher in strokes involving the right insula (39%) than in strokes involving the left insula (4%) [61]. Notably, cardiac structure and function changes during AF in patients with stroke [62]. ECG abnormalities after AIS correlate strongly with neurological outcomes.…”
