Pulmonary Hypertension on Prognosis of Acute Myocardial Infarction Patients With Reduced Left Ventricular Function

First Affiliated Hospital Xi'an Jiaotong University4,784 enrolled

Overview

Pulmonary hypertension (PH) has a negative effect on acute myocardial infarction (AMI) patients and appears to be closely associated with reduced left ventricular function. However, its impact on AMI patients with reduced left ventricular function remains unclear. This retrospective study included AMI patients with reduced left ventricular function to investigate the prognostic value of PH in this specific type of patient. Meanwhile, a nomogram would be established basing on the identified independent risk factors, hoping to provide a novel risk stratification for them.

Inclusion Criteria: * The patients who were hospitalized for AMI with reduced left ventricular function at the First Affiliated Hospital of Jiaotong University from January 2018 to January 2022. Exclusion Criteria: * Myocardial infarction complicated by cardiac rupture. * Significant pre-existing heart failure. * Other comorbidities such as malignancy that may significantly affect prognosis. * Incomplete clinical data.

Outcomes

Primary Outcomes

The incidence of all-cause death

All-cause death will be determined by clinical records or phone calls with patients and their family.

Time frame: 1-year after the AMI.
