The effects of vericiguat on cardiac remodeling in patients with chronic stable heart failure after myocardial infarction have not been reported. This project aims to clarify the efficacy and safety of vericiguat in patients with chronic heart failure after myocardial infarction. Patients with chronic stable heart failure with reduced ejection fraction after myocardial infarction in the electronic medical records of Qilu Hospital of Shandong University will be selected and divided into two groups: the treatment group received vericiguat in addition to conventional treatment and the control group received conventional treatment only. After 12-month treatment, the effects of vericiguat on cardiac remodeling and function and cardiovascular adverse events will be evaluated. The results are helpful to provide a new treatment strategy for chronic heart failure after myocardial infarction.

Inclusion Criteria:

4. NYHA cardiac function classified as grade II~IV;
5. LVEF≤40%；
6. NT-proBNP≥450pg/ml；
7. All subjects or their guardians must sign the subject consent before entering the trial.

Exclusion Criteria:

2. Mechanical complications of myocardial infarction;
3. Unable to obtain primary outcome data.
