Clinical Study and Molecular Mechanism of Xuesaitong Soft Capsule in the Treatment of Acute Coronary Syndrome

Clinical Study and Molecular Mechanism of Xuesaitong Soft Capsule in the Treatment of Acute Coronary Syndrome After Percutaneous Coronary Intervention

To evaluate the platelet function, clinical efficacy, prognosis and safety of Xuesaitong soft capsule in the treatment of acute coronary syndrome, 50 patients with acute coronary syndrome after PCI were treated with Xuesaitong soft capsule (mainly Panax notoginseng saponins) for 4 weeks.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Transcriptome analysis of patients' platelets collected before and after treatment	This measure involves the collection of patients' platelets for comprehensive transcriptome analysis. This analysis aims to identify changes in gene expression profiles before and after treatment. Data will be summarized based on differentially expressed genes, providing insights into the impact of treatment on platelet function at the transcriptional level.	4 weeks
Metabolomics analysis of patients' platelets collected before and after treatment	This measure involves the collection of patients' platelets for comprehensive metabolomics analysis. This analysis aims to identify changes in metabolic pathways and metabolites before and after treatment. Data will be summarized based on identified metabolites and altered metabolic pathways, which will help elucidate the treatment's effects on platelet function at the metabolic level.	4 weeks
Proteomics analysis of patients' platelets collected before and after treatment	This measure involves the collection of patients' platelets for comprehensive proteomics analysis. This analysis aims to identify changes in protein expression patterns before and after treatment. Data will be summarized based on differentially expressed proteins, providing insights into the treatment's impact on platelet function at the proteomic level.	4 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Changes in platelet granule markers, including platelet factor 4 (PF4) and β-thromboglobulin, before and after treatment, as assessed by ELISA	This outcome measure will assess changes in platelet granule markers, including platelet factor 4 (PF4) and β-thromboglobulin, before and after treatment. Both markers will be measured using enzyme-linked immunosorbent assay (ELISA) and reported in consistent units (pg/mL). Data will be summarized based on the change in levels of each marker from baseline to post-treatment, and any significant changes will be noted.	4 weeks

Additionally, platelet-neutrophil aggregation will be assessed by measuring the co-expression of CD41 (platelet marker) and CD15 (neutrophil marker). These analyses will quantify the impact of treatment on platelet activation and the interaction between platelets and neutrophils, with results presented as mean fluorescence intensity for each marker. Changes will be compared before and after treatment.	4 weeks

Assessment of electrocardiogram (ECG) parameters, including QT interval, heart rate, and ST segment changes, before and after treatment	This measure involves evaluating various ECG parameters to monitor cardiac electrical activity. Specifically, it includes the measurement of the QT interval, heart rate, and any changes in the ST segment.
