简要总结
Myocardial remodeling following myocardial infarction (MI) is an important prognostic factor for heart function and adverse cardiovascular events, especially are intimately linked with heart failure. MI often causes deleterious changes in ventricular size, shape, and function. This adverse remodeling and progress is mediated by neurohormonal and hemodynamic alterations. The angiotensin receptor neprilysin inhibitor (ARNI) sacubitril/valsartan was shown to be superior to an ACE inhibitor in patients with heart failure with reduced ejection fraction (HF-REF), reduce the risk of both death (from cardiovascular and all-causes) and heart failure hospitalization, may be a new approach to the treatment of heart failure. However, the impact of early treatment of ARNI on myocardial remodeling and progress, and aerobic exercise capacity in patients with prior MI has yet to be assessed. The aim of this study is to evaluate the efficacy and the safety of early treatment of ARNI on myocardial remodeling and progress, and aerobic exercise capacity in patients following MI.
详细描述
Myocardial remodeling following myocardial infarction (MI) is an important prognostic factor for heart function and adverse cardiovascular events. The angiotensin receptor neprilysin inhibitor (ARNI) sacubitril/valsartan was shown to reduce the risk of both death (from cardiovascular and all-causes) and heart failure hospitalization. However, whether early treatment of ARNI following post-MI could alter myocardial remodeling or aerobic exercise capacity has yet to be assessed. The patients with MI within one month were enrolled in the treatment of ARNI group or ACEI group. The study proposes to perform serial Cardiopulmonary Exercise Tests (CPET) to prospectively measure changes in aerobic exercise capacity in patients with prior myocardial infarction (MI), echocardiographic measures of LV end-diastolic/ systolic volumes, LV ejection fraction (LVEF), BNP and protein plasma levels, symptomatic heart failure, and life quality.
