A Privacy-Preserving OCR-LLM System for Coronary Syndrome Subtyping From Admission HPI: Multicenter Validation in China and the US

This study develops and validates a privacy-preserving OCR-LLM pipeline that converts admission history of present illness (HPI) records into structured coronary syndrome subtypes (STEMI, NSTEMI, unstable angina, and chronic coronary syndrome). The system first extracts text from de-identified HPI images using locally deployed OCR, then applies large language models with a fixed diagnostic prompt to generate subtype classification and evidence. Performance is evaluated in an internal validation cohort and multiple external datasets covering heterogeneous EHR templates, emergency department cases, and an English dataset from MIMIC-IV. A clinician usability study assesses changes in diagnostic accuracy and time with and without tool assistance.

Systemic Organ Communication in STEMI

Despite progress in pre-hospital care, ambulance logistics, pharmacotherapy and PPCI techniques, ST-segment elevation myocardial infarction (STEMI) continues to confer a substantial burden of morbidity and mortality. Within the STEMI population, there is a spectrum of higher and lower risk patients. The aim of this cohort study is to collect prospectively and systematically clinical research data from STEMI patients. This cohort study is an open-end observational study to identify master switches in myocardial ischemia.

Intracoronary rhTNK-tPA Versus Tirofiban in Patients With STEMI and High Thrombus Burden

The goal of this clinical trial is to compare the efficacy and safety of intracoronary rhTNK-tPA or Tirofiban in patients with ST-segment elevation myocardial infarction and high thrombus burden. The main questions it aims to answer are: * Is the efficacy of intracoronary rhTNK-tPA non-inferior to intracoronary Tirofiban for the treatment of ST-segment elevation myocardial infarction in patients wiht high thrombus burden? * Does intracoronary rhTNK-tPA increase the incidence of bleeding events? This multicenter RCT study plans to enroll 300 patients, who are randomly divided into two groups: intracoronary rhTNK-tPA or Tirofiban by 1:1. The primary efficacy endpoint was post-PCI corrected TIMI frame count (CTFC). Major adverse events (death, recurrent myocardial infarction, ischemic stroke, or hospitalization for heart failure) were observed at 1 year follow-up.

Coronary Aspiration Catheter Clinical Trial

To evaluation of the efficacy and safety of an aspiration catheter in patients undergoing PCI for acute ST-segment elevation myocardial infarction (STEMI).

MAchine Learning to Boost the Early Diagnosis of Acute Cardiovascular Conditions

The research project aims to develop clinical decision support tools integrating established diagnostic variables and machine learning (ML) models for rapid diagnosis of acute life-threatening cardiovascular conditions in emergency department (ED) patients with chest pain or dyspnea with the ultimate goal of Improved diagnostic accuracy, faster patient management, and reduced medical errors.

Bivalirudin with Prolonged Infusion During PCI Versus Heparin After Fibrinolytic Therapy

This multicenter, randomized controlled trial in China aims to enroll 2,400 patients with ST-segment elevation myocardial infarction undergoing percutaneous coronary intervention (PCI) within 24 hours post-fibrinolysis. Participants will be randomly assigned in a 1:1 ratio to receive either bivalirudin or heparin, with follow-up at 30 days and 1 year. The primary endpoint is a composite of all-cause mortality and Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding at 30 days.

Effect of Dapagliflozin in Myocardial Fibrosis and Ventricular Function in Patients With a ST-segment Elevation Myocardial Infarction

The DAPA-STEMI trial investigates whether dapagliflozin, a sodium-glucose cotransporter 2 inhibitor (SGLT2i), reduces heart muscle scarring (fibrosis) and improves heart function after a ST-segment elevation myocardial infarction (STEMI). The trial will use cardiac MRI to measure changes in heart structure and function over six months. Patients aged 30-85 who have had a recent STEMI will receive either dapagliflozin or a placebo. The study aims to provide mechanistic insights into heart failure prevention after heart attacks.

The Effect of Morning vs Evening Aerobic Exercise Training on Cardiac Remodeling and Function Improvement in Patients After ST Elevation Myocardial Infarction

The aim of the study was to intervene in the Aerobic exercise time of patients with STEMI and to explore the optimal exercise time for STEMI patients

A Randomized Controlled Trial on the Efficacy and Safety of Butylphthalide in Reducing Myocardial Infarction Size and Improving Outcomes in STEMI Patients After Primary PCI

This study is a prospective, randomized, placebo-double-blind, multicenter clinical trial. The purpose of this study is to investigate whether "butylphthalide +PCI" combined treatment mode on the basis of traditional drug therapy could reduce myocardial infarct size, improve cardiac function and long-term prognosis of patients with acute myocardial infarction, and verify the drug safety of butylphthalide in the treatment of STEMI within the window period of 12 hours.

Thrombus Aspiration in STEMI Patients With High Thrombus Burden

This is a prospective, multicenter, open-label, randomized, controlled, parallel group study, in which ST-segment Elevation Myocardial Infarction (STEMI) patients with high thrombus burden(TIMI thrombus grade ≥3) are included. Patients are randomized to be treated with or without manual thrombus aspiration(TA) during primary percutaneous coronary intervention(PPCI) by a ratio of 1:1.

Cardioprotective Effect of Dexmedetomidine in Patients With ST-segment Elevation Myocardial Infarction

This is a double-blind, multicenter, randomized, placebo-controlled clinical trial. It is planned to enroll patients admitted with anterior ST-segment elevation myocardial infarction (STEMI) within 6h of symptom onset and undergo primary percutaneous coronary intervention (pPCI). Patients who meet the inclusion criteria and without exclusion criteria were randomized 1:1 into the dexmedetomidine (DEX) group or the placebo (saline) group after signing the informed consent. In the DEX group, intravenous injection of DEX was started immediately after enrollment, covering the entire PCI operation, and the administration was stopped at the end of the pPCI. The administration of saline was the same as those in the DEX group. The primary endpoint was the myocardial infarct size (MIS) as assessed by cardiac magnetic resonance imaging (CMR) at 5±2 days post-STEMI. Based on a superiority design and assuming an 20.0% relative infarct size reduction (from 26.0% to 20.8% with a SD of 13.0%), 250 patients are required to be enrolled, accounting for 20% drop-out (α= 0.05 and power= 80%).

Researchers will collect information based on hospital registry as secondary data of in patient who had diagnosed as ST-segment elevation myocardial infarction and underwent primary percutaneous coronary intervention. The data consist of demographic data, clinical presentation, laboratory, and angiography result were collected from hospital registry by reviewing medical record. Then, the data was analyzed by using IBM SPSS Statistics v26.
