Predictors and Outcomes of In-hospital HFpEF in AMI Patients

Predictors and Outcomes of Hospitalized Heart Failure With Preserved Ejection Fraction Among Patients With First Acute Myocardial Infarction After Reperfusion Treatments

This retrospective observation is to investigate the incidence,clinical outcomes and prognosis of hospitalized heart failure with preserved ejection fraction (HFpEF) in patients with acute myocardial infarction(AMI).

1. Patients with first AMI undergoing primary percutaneous coronary intervention (PCI) in our hospital since January 2013 were retrospectively evaluated. The enrolled subjects were divided into two groups (AMI patients with HFpEF and AMI patients without HF).
2. The investigator collected the clinical data of participants' demographics (age, sex), previous history,risk factors for AMI (hypertension, hyperlipidemia, diabetes mellitus, smoking and stroke), laboratory biomarkers, echocardiographic measurements, clinical characteristics,medical procedures and treatments, as well as in-hospital complications.
3. Two sub-investigators independently analyzed these data by using SPSS software.

Inclusion Criteria:

• First AMI patients undergoing PCI with HFpEF or without HF.

Exclusion Criteria:

• First AMI patients with heart failure with reduced ejection fraction.
• First AMI patients with severe inflammatory diseases, valvular heart disease, non-cardiac caused symptoms, serious hepatic and renal failure, congenital cardiomyopathy,or pericardial diseases.
