According to scarce data, iron deficiency (ID) is a risk factor for worsening prognoses of ischemic heart disease, in particular, myocardial infarction (MI).

The purpose — to study the changes in the maximal volume of left atrium in patients with ID treated with iron supplements and normal iron status within 6 months after myocardial infarction.

Material and methods. The study included 146 patients (54 women (37%) and 92 men (63%)) hospitalized Municipal Clinical Hospital No. 7 named after M.N. Sadykov with myocardial infarction in 2022. The patients were divided into 2 groups: group 1 comprised 80 (55%) patients with iron deficiency, and group 2 consisted of 66 (45%) patients without iron deficiency. The groups were comparable in terms of gender, comorbidities and drug therapy. The patients underwent correction of iron deficiency, echocardiographic examination in the first 24 hours after hospitalization and 6 months later to assess changes in target cardiac parameters.

Results. We found a statistically significant increase in median left atrium volume after 6 months compared with the initial volume in patients in group 2 (63.0 ml (49–65) and 58.5 ml (47‒64), respectively (р < 0.001). In group 1, left atrium volume did not change (р = 0.145). There was no statistically significant difference in median left atrium volume in groups 1 and 2 both initially and after 6 months (p = 0.390).

Conclusion. Our results indicate that there was no increase in left atrium volume within 6 months after myocardial infarction in patients who underwent ID correction.

Key words: iron deficiency, myocardial infarction, maximal left atrium volume.
