Insights
Despite advances in treatment, many myocardial infarction survivors develop adverse cardiac remodeling and left ventricular (LV) dilatation. This progression can lead to heart failure, necessitating new therapeutic strategies.
Area of Science:
- Cardiology
- Cardiovascular Research
- Pathophysiology
Context:
- Myocardial infarction (MI) remains a leading cause of heart disease.
- Despite current treatments, a significant percentage of patients experience unfavorable cardiac remodeling and left ventricular (LV) dilatation post-MI.
- This remodeling process is linked to systolic and diastolic dysfunction, potentially leading to heart failure.
Purpose:
- To review the current understanding of post-infarction cardiac remodeling.
- To highlight the ongoing challenges in managing unfavorable remodeling after myocardial infarction.
- To emphasize the need for novel therapeutic approaches to prevent or reverse cardiac remodeling and its consequences.
Summary:
- Adverse cardiac remodeling, characterized by left ventricular (LV) dilatation, affects 20-30% of myocardial infarction (MI) survivors long-term.
- This pathological process involves structural and functional changes, including myocardial dysfunction, and can precipitate heart failure.
- Recent research increasingly suggests that LV remodeling may be reversible, driving the search for targeted interventions.
Impact:
- Improved understanding of cardiac remodeling mechanisms post-MI.
- Potential for developing new, specific therapies to counteract adverse remodeling.
- Reduced incidence of heart failure in post-MI patients.
- Enhanced long-term outcomes and quality of life for myocardial infarction survivors.
Abstract:
Despite the considerable progress in the setting of invasive and pharmacological treatment still in about 20-30% patients with myocardial infarction in long-term observation an unfavourable post-infarction remodeling along with development of LV dilatation is to be seen. The heart forms the structural and functional unity, thus morphological changes due to cardiac post-infarction remodeling process are accompanied by systolic and diastolic myocardial dysfunction, which in consequence may lead to appearance of heart failure. In recent years our knowledge regarding causative factors of post-infarction cardiac remodeling has been remarkably widening and in the light of accumulating data indicating the possibility of LV remodeling regression, elaboration of the new specific-orientated methods of counteracting its uneventful consequenses is a matter of time.
