Effects of Nicorandil on Microvascular Dysfunction in Patients With STEMI Undergoing Primary PCI

Despite the success of restoration of epicardial blood flow by the primary percutaneous coronary intervention (PPCI), approximately one half of patients with ST-segment elevation myocardial infarction (STEMI) have failed myocardial reperfusion, namely microvascular dysfunction. Previous studies have shown that coronary microvascular damage significantly impacts the prognosis of patients with STEMI. Therefore, restoration of microvascular function is quite important during the PPCI procedures. Recent clinical trials found that nicorandil, a hybrid ATP-sensitive potassium channel opening agent, improved microvascular function, prevented no-reflow phenomenon, and had beneficial cardioprotective effects in patients receiving PPCI. However, there was a lack of evidence on the protective effects of nicorandil on microvascular function. The coronary angiography-derived IMR (AMR) is a novel wire-free technology developed for fast computation of IMR in patients undergoing coronary angiography, thereby enabling the quantification of coronary microcirculation of patients. This study is aimed to investigate the effects of nicorandil on microvascular dysfunction as evaluated by AMR in patients with STEMI.

Metabolic Characteristics of Plasma OxPLs in STEMI Patients.

The goal of this observational study is to investigate the structural composition and metabolic characteristics of OxPLs in STEMI patients. Explore OxPLs characteristic fingerprint biomarkers from different populations and analyze OxPLs fingerprint spectra. Based on the OxPLs fingerprint of STEMI patients, a machine learning classifier is used to establish an artificial intelligence assisted post PCI MACE risk prediction system, achieving the transformation of basic research into clinical application.
