Abstract Patients with acute myocardial infarction (AMI) complicated by left ventricular dysfunction have an increased risk of death and heart failure. Numerous clinical studies have demonstrated the ability of ACE inhibitors in optimizing the outcome in this particular clinical setting. In recent years, the sacubitril/valsartan association has drastically improved the prognosis of patients with heart failure with reduced ejection fraction with a significant decrease in mortality from cardiovascular causes and hospitalizations due to acute heart failure. However, it has not yet been fully clarified whether this pharmacological association may play a role in patients with AMI. Pre-clinical studies have suggested the possibility that sacubitril/valsartan can reduce the size of the infarct scar and prevent the onset of ventricular arrhythmias in laboratory animals in which myocardial infarction was induced. On the other hand, small clinical experiences with patients after myocardial infarction have provided conflicting data. The results of the PARADISE-MI study were recently presented, which enrolled 5661 patients with AMI complicated by pulmonary congestion and left ventricular dysfunction randomized to therapy with ramipril or sacubitril/valsartan and followed up for ∼2 years. Although combination therapy was associated with an ∼10% reduction in the risk of death from cardiovascular causes or an episode of heart failure, this was not enough to achieve statistical significance. However, treatment with sacubitril/valsartan was shown to be more effective than ramipril in preventing recurrence of heart failure after the first one.

Abstract Background Smoking is associated with higher morbidity and mortality following myocardial infarction (MI), but reports of the impact on cardiovascular (CV) death in aged and female patients experiencing MI complicated with left ventricular dysfunction or overt heart failure are limited. Methods In an individual patient data meta-analysis of high-risk MI patients, the association of smoking to CV death was investigated. Cox proportional hazard models exploring smoking status and risk according to age and sex were performed to study the relationship of smoking to independently adjudicated CV death endpoints. Results 28,771 patients from the CAPRICORN, EPHESUS, OPTIMAAL and VALIANT trials were assessed. 18,325 (64%) reported smoking (9185 (32%) current and 9051 (32%) past), 2662 (9%) were above ≥80 years and 8607 (30%) were women. Overall, using non-smokers as referent, the association of smoking to CV mortality was neutral (HR=1.07, 0.98 to 1.16, p=0.12 for active smoking and HR=1.10, 1.02 to 1.18, p=0.01 for past smoking). The associations for active and past smokers with outcome, adjusted for age and sex in the overall study sample and according to different age and sex categories, are presented in figure 1. In analyses that included interaction terms, the association for active smokers depended on age and sex; the risk of CV mortality was weakened in women (interaction HR=0.81, 0.69 to 0.96, p=0.01) and older age (interaction HR per 10 years increase=0.88, 0,82 to 0.95, p=0.001). In contrast, the association to CV death for past smokers was not modified by sex or age (p=0.86 and p=0.17 respectively). Conclusions The association of smoking to CV death differed according to age and sex in MI complicated with left ventricular dysfunction or overt heart failure. Significant association of active and/or past smoking with increased risk of CV death was mainly observed in the 60–69 years category. The underlying reasons of the lack of association of smoking with outcome in older patients in this specific context should be explored further in future studies.
