[Auricular fibrillation in myocardial infarct]

Area of Science:

• Cardiology
• Internal Medicine
• Clinical Research

Context:

• Large-focal myocardial infarction presents a significant clinical challenge.
• Auricular fibrillation is a common complication impacting patient outcomes.
• Understanding risk factors and predictors is crucial for patient management.

Purpose:

• To investigate the incidence and predictors of auricular fibrillation in patients with large-focal myocardial infarction.
• To analyze the impact of auricular fibrillation on mortality and prognosis.
• To identify potential early warning signs for auricular fibrillation.

Summary:

• Auricular fibrillation was observed in 17.8% of patients with large-focal myocardial infarction, with a higher incidence noted in females (p < 0.01).
• Myocardial infarction localization did not influence auricular fibrillation rates. Precursors included atrial extrasystoli and elevated blood NaeKe electrolyte coefficient.
• Mortality was higher in females with myocardial infarction and auricular fibrillation. Auricular fibrillation developing after the first postinfarction day significantly worsened prognosis.

Impact:

• Identifies key predictors like atrial extrasystoli and electrolyte imbalances for early auricular fibrillation detection.
• Highlights the increased mortality risk in females and the negative prognostic impact of delayed auricular fibrillation onset.
• Provides crucial insights for refining clinical management strategies and improving outcomes for myocardial infarction patients complicated by auricular fibrillation.
