Prognostic Factors in patients with STEMI Treated by pPCI is a retrospective observational study in China.This study aims to identify the main prognostic factors to recognize patients with increased major adverse cardiovascular events risks and conduct a further intervention for these patients. The study will provide clinical, functional, and invasive treatment measures with systematic serial sampling and evaluation. Moreover, the knowledge on the prognostic factors of STEMI patients treated by primary percutaneous coronary intervention will be increased.


Currently, primary percutaneous coronary intervention is the first choice for patients with acute ST-segment elevation myocardial infarction. In the past 40 years, the development of rapid reperfusion therapy has gradually reduced the mortality rate of cardiovascular disease. Compared with drug thrombolysis therapy, pPCI can effectively improve epicardial blood flow reperfusion, reduce infarct size and improve survival rate.

However, although epicardial blood flow reperfusion in patients with STEMI can be improved by pPCI, the short-term and long-term major adverse cardiovascular events (MACE) in patients with STEMI caused by ischemia-reperfusion injury, no-reflow phenomenon, microvascular obstruction, and delayed microvascular perfusion are still worrying. Clinical studies have reported that mechanical hemodynamic support device is not satisfactory for STEMI patients who still develop circulatory failure after pPCI treatment, and it may only have a better effect on high-risk patients. Clinical studies reported that the incidence of in-hospital congestive heart failure in STEMI patients treated with pPCI was 6%. One retrospective study of 251079 patients with STEMI by Wu et al showed that the in-hospital mortality rate of STEMI patients could be as high as 9.2%. However, there are no reliable scoring criteria to evaluate the incidence of acute congestive heart failure after pPCI in patients with STEMI.

As STEMI patients are often complicated with hypertension, hypercholesterolemia, diabetes, and other risk factors, each patient may face a different situation and more personalized assessment criteria are needed to deal with complex clinical problems, especially for those at high risk. We are committed to developing a prediction model to predict the risk of in-hospital acute heart failure in STEMI patients treated with pPCI, to adjust the diagnosis and treatment plan for those medium-and high-risk patients.
