Outcome of Discharged HFmrEF Patients

Study Overview
=================
Brief Summary
-----------------
This study aimed to define the independent risk factors related cardiac events (cardiac death or heart failure-related hospitalization) among heart failure with mildly reduced ejection fraction (HFmrEF) patients who discharged from the Xiangtan Central Hospital. Through the long-term follow-up the cardiovascular outcome of patients being discharged from the hospital, the risk factors related to cardiovascular outcome (cardiac death or heart failure-related hospitalization) will be explored to provide clinical evidence to intervene the discharged HFmrEF patients aiming to improve patients outcome in the future clinical practice.

Detailed Description
-----------------
This study aimed to define the independent risk factors related cardiac events (cardiac death or heart failure-related hospitalization) among heart failure with mildly reduced ejection fraction (HFmrEF) patients who hospitalized in Xiangtan Central Hospital from January 1, 2015 to August 31, 2020. The patients would be clinically followed-up until August 31, 2021 per clinical visit or telephone call, the risk factors related to cardiovascular outcome (cardiac death or heart failure-related hospitalization) will be explored to provide clinical evidence to intervene the discharged HFmrEF patients aiming to improve patients outcome in the future clinical practice. The clinical features of hospitalized heart failure with mildly reduced ejection fraction (HFmrEF, EF 41-49%) will be analyzed by retrospectively by reviewing patients medical records, laboratory and clinical imaging examination results during initial hospitalization, clinical outcome of enrolled patients will be obtained through clinical visit and telephone call. The primary endpoint is the composite cardiac events (cardiac death or heart failure related rehospitalization). The secondary endpoint is the all-cause death.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Long-term risk factors related to cardiac events (cardiac death or heart failure-related rehospitalization) in discharged patients with heart failure with mildly reduced ejection fraction | Primary Outcome Measure: 1.Long-term risk factors related to cardiac events (cardiac death or heart failure-related rehospitalization) in discharged patients with heart failure with mildly reduced ejection fraction The clinical features of hospitalized heart failure with mildly reduced ejection fraction (HFmrEF, EF 41-49%) will be analyzed retrospectively by reviewing their medical records, laboratory and clinical imaging examination results during initial hospitalization, clinical outcome up to the study end will be obtained through clinical visit and telephone call. | The last patients would be clinically followed-up until August 31, 2021 per clinical visit or telephone call. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Long-term risk factors related to all-cause death in discharged patients with heart failure with mildly reduced ejection fraction | 1. Long-term risk factors related to all-cause death in discharged patients with heart failure with mildly reduced ejection fraction The clinical features of hospitalized heart failure with mildly reduced ejection fraction (HFmrEF, EF 41-49%) will be analyzed retrospectively by reviewing their medical records, laboratory and clinical imaging examination results during initial hospitalization, all-cause death up to the study end will be obtained through clinical visit and telephone call. | The last patients would be clinically followed-up until August 31, 2021 per clinical visit or telephone call |
