Insights

Admission copeptin levels predict left ventricle (LV) systolic function in ST-segment elevation myocardial infarction (STEMI) patients. Higher copeptin correlates with poorer LV systolic function and less improvement over six months.

Area of Science:

  • Cardiology
  • Biomarkers
  • Echocardiography

Background:

  • ST-segment elevation myocardial infarction (STEMI) poses significant risks to left ventricle (LV) systolic function.
  • Early identification of patients at risk for impaired LV function is crucial for timely intervention.
  • Copeptin, a marker of stress, has been investigated for its prognostic value in cardiovascular diseases.

Purpose of the Study:

  • To investigate the association between admission copeptin levels and LV systolic function in STEMI patients.
  • To assess the relationship between copeptin and the improvement of LV systolic function at 6-month follow-up.
  • To determine if copeptin can predict early and long-term LV systolic function in STEMI.

Main Methods:

  • A prospective observational study included 122 STEMI patients.
  • LV systolic function was assessed using global longitudinal strain (GLS) and conventional echocardiography on admission and at 6 months.
  • Serum copeptin levels were measured using an ultrasensitive immunofluorescence assay.

Main Results:

  • Patients with high admission copeptin levels showed significantly lower GLS at both early stage and 6 months compared to those with low copeptin.
  • Copeptin levels were negatively correlated with early and 6-month GLS.
  • Admission copeptin levels were also negatively correlated with the improvement of GLS at 6-month follow-up.

Conclusions:

  • Admission serum copeptin levels can predict early and 6-month LV systolic function in STEMI patients, as assessed by GLS.
  • This study is the first to specifically link copeptin values with GLS in the context of STEMI.
  • Copeptin may serve as a valuable biomarker for assessing LV systolic function and recovery post-STEMI.
