Aim: To assess an impact of clinical and medical history factors and antithrombotic therapy on the prognosis in patients with non-valvular atrial fibrillation (AF) admitted to the cardiology in-patient clinic for myocardial infarction (MI). Materials and methods: This was a retro-prospective study. Two hundred and fifty six (256) patients with AF plus MI (median age 71.0 [65.0; 79.3] years; men, 143 (55.8%)) were included into the retrospective part of the study in 20182019. Data on their clinical and medical history particulars, as well as on antithrombotic therapy were collected from their medical files. Nineteen (19) [13; 25] months after the index event (MI), telephone contact was made with patients or their relatives in order to assess the patient's life status, as well as record the frequency of non-fatal MI and cerebral strokes (MI). Contact was established with 253 patients. The completeness of the sample coverage is 99.0%. Results: During the follow-up after discharge from the hospital, 29.6% (n = 75) of patients died, 40.7% (n = 103) of patients reached the composite endpoint (CЕ), which included deaths, non-fatal MI and brain strokes. The patients who died, compared to those who survived, were older (77.0 [62.0; 82.0] vs 68.0 [62.0;76.7] years, respectively, p 0.001), with a smaller proportion of men (44.0% vs 61.2%, respectively, p = 0.012). They were also more likely to have had type 2 diabetes mellitus (50.7% vs 37.1%, p = 0.04) and the history of acute stroke (24.0% vs 8.4%, p 0.001), and less likely to have had percutaneous coronary intervention (48.0% vs 64.0%, p 0.001). Serum creatinine levels in those who have died were higher than in the surviving patients (114.0 [95.0; 139.0] mmol/l vs 99.5 [85.0; 120.0] mmol/l, p 0.001). The patients who have achieved CE, compared to those who have not, were older (75.0 [67.0; 81.0] vs 65.0 [50.0; 82.0] years, respectively, p 0.001), with a smaller proportion of men (48.5% vs 61.3%, respectively, p = 0.045), higher proportion of patients with past history of stroke (20.4% vs 8.0%, p = 0.005) and fewer patients who had underwent percutaneous coronary intervention (52.4% vs 66.0%, p 0.03). There was no significant association between the administration of anti-platelet agents and/or oral anticoagulants and outcomes in the patients with AF and MI. Conclusion: In the patients with AF and MI, a higher death risk and achievement of CE were significantly associated with age and a history of stroke. The use of anti-platelet agents and oral anticoagulants in various combinations had no significant impact on the outcomes in this patient group, which is likely related to small duration of the follow-up and small patient sample.
Post-infarction left ventricular aneurysm (LVA) is a complication of myocardial infarction (MI), which is of great clinical importance due to high mortality. Data on its incidence are contradictory. The aim of the review was to highlight the existing and novel predictors of post-infarction LVA, the identification of which will help in identifying high-risk patients in order to optimize their treatment and rehabilitation. Known predictors of post-infarction LVA include pain-to-balloon time, age, female sex, recurrent MI, coronary angiography parameters, echocardiography, and electrocardiography. Increased levels of leukocytes, C-reactive protein, growth differentiation factor, stimulating growth factor, interleukin-1β, interleukin-6, tumor necrosis factor-α, matrix metalloproteinases, proprotein convertase subtilisin-kexin type 9, N-terminal pro-brain natriuretic peptide >400 pg/ml indicate the risk of pathological left ventricular remodeling and LVA. In this connection, there is a need to assess the incidence of post-infarction LVA and a comprehensive assessment of its predictors in patients with MI.
