Insights
Left ventricular remodeling (LVR) after myocardial infarction (MI) significantly increases long-term risks for heart failure (HF) and cardiovascular death, even with optimal secondary prevention medication use.
Area of Science:
- Cardiology
- Clinical Medicine
- Cardiovascular Research
Background:
- Left ventricular remodeling (LVR) is a known risk factor post-myocardial infarction (MI).
- Its association with heart failure (HF) and death in patients on optimal secondary prevention requires further study.
Purpose of the Study:
- To investigate the long-term prognostic significance of LVR after MI.
- To assess the impact of LVR on cardiovascular death and HF hospitalization in patients receiving contemporary secondary prevention.
Main Methods:
- Long-term clinical follow-up of patients from two prospective multicentric studies.
- Echocardiography at 1 year post-MI to assess LVR (≥20% increase in end-diastolic volume).
- Analysis of cardiovascular death and HF hospitalization rates, adjusted for baseline characteristics.
Main Results:
- LVR occurred in 31% and 38% of patients across two cohorts.
- High prescription rates for beta-blockers and ACE-I/ARBs were observed (>90%).
- LVR was independently associated with a significantly increased risk of cardiovascular death or HF hospitalization (p < 0.01).
Conclusions:
- Left ventricular remodeling (LVR) remains a significant independent predictor of adverse outcomes post-MI.
- This association persists despite high adherence to evidence-based secondary prevention therapies.
Background:
The association of left ventricular remodeling (LVR) after myocardial infarction (MI) with the subsequent risk of heart failure (HF) and death has not been studied in patients receiving optimal secondary prevention.
Methods And Results:
We performed a long-term clinical follow-up of patients included in 2 prospective multicentric studies on LVR after first anterior MI. At 1-year echocardiography, LVR (≥20% increase in end-diastolic volume from baseline to 1 year) occurred in 67/215 (31%) patients in cohort 1 and in 87/226 (38%) patients in cohort 2. The prescription rate of secondary prevention medications was very high (ß-blockers at 1 year: 90% and 95% for cohorts 1 and 2, respectively; angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (ACE-I/ARB) at 1 year: 93% and 97% for cohorts 1 and 2, respectively). Median clinical follow-up after LVR assessment was 11.0 years in cohort 1 and 7.8 years in cohort 2. In both cohorts, LVR patients had a progressive increase in the risk of cardiovascular death or hospitalization for HF (p = 0.0007 in cohort 1 and 0.009 in cohort 2) with unadjusted hazard ratios of 2.52 [1.45-4.36] and 2.52 [1.23-5.17], respectively. Similar results were obtained when cardiovascular death was considered as an isolated endpoint. After adjustement on baseline characteristics including ejection fraction, the association with the composite endpoint was unchanged.
Conclusion:
In a context of a modern therapeutic management with a large prescription of evidence-based medications, LVR remains independently associated with HF and cardiovascular death at long-term follow-up after MI.
