Key result
Post-MI heart failure > NYHA II is linked to more frequent major events at one year.
Why the study?
An increasing number of post-myocardial infarction patients contributes to a higher long-term incidence of chronic cardiovascular diseases, prompting the need to identify key clinical and functional markers characterizing acute and chronic heart failure after myocardial infarction.
Population
186 patients who had myocardial infarction
Comparison
Signs of CHF above NYHA FC 2 (n=86) vs without signs of CHF or CHF NYHA 1 FC (n=100)
Follow-up
1 year

Post-MI HF >NYHA II may warrant closer surveillance; leaves open whether targeted interventions improve outcomes in Level 5 data.
Cohort (n=186)
Patients developing significant chronic heart failure (NYHA > II) after myocardial infarction have a higher risk of adverse outcomes at 1 year, and subanalysis suggests ARNI therapy may reduce cardiovascular death compared to enalapril in this population.
Ложкина et al. (2021) conducted a cohort in myocardial infarction (n=186). Heart failure > NYHA class II vs. No heart failure or NYHA class I was evaluated on One-year unfavorable outcomes (cardiovascular death, repeated hospitalizations due to decompensation of CHF, death from other causes, stroke, repeated myocardial infarction, unplanned coronary revascularization). Following myocardial infarction, patients developing heart failure > NYHA class II experienced significantly more frequent one-year unfavorable outcomes compared to those with mild or no heart failure.
