Certainly in a clinical ST elevation myocardial infarction (STEMI) population who underwent coronary revascularization, high NPY levels appeared to be correlated with increased severity of ventricular arrhythmias during inpatient admission, despite similar left ventricular ejection fractions, troponin levels and beta-blocker usage (Herring et al., 2016). Here, NPY is linked to Ventricular arrhythmia.
