Clonal Hematopoiesis on Prognosis in Patients With Myocardial Infarction

To Investigate the Effect of CHIP on Renal Insufficiency in AMI Patients

This is an observational study without intervention. It is planned to include 500 patients with AMI from October 2023 to July 2026.The study was divided into three parts. Part I: To investigate the effect of CHIP on renal insufficiency in AMI patients. Part two: To investigate the effect of CHIP on cardiovascular outcomes in patients with AMI complicated with CKD stage II-IV nephropathy. Part three: To investigate the effects of CHIP on cardiovascular and renal outcomes in AMI patients with ESRD. Study endpoint: Primary end points: all-cause death, cardiac death, and nonfatal myocardial infarction. Secondary endpoints: angina pectoris requiring hospitalization, nonfatal stroke, and nonfatal heart failure.

This is an observational study without intervention. It is planned to include 500 patients with AMI from October 2023 to July 2026.The study was divided into three parts. Part I: To investigate the effect of CHIP on renal insufficiency in AMI patients. Patients with confirmed AMI were divided into two groups based on eGFR values: AMI+ normal renal function group (eGFR≥90 ml/min); AMI+ renal dysfunction group (eGFR \< 90 ml/min). Main outcome measures: CHIP carrying frequency, expression levels of IL-1β, IL-6, CRP, TNF-α, NLRP3 and other inflammatory factors. Part two: To investigate the effect of CHIP on cardiovascular outcomes in patients with AMI complicated with CKD stage II-IV nephropathy. Patients with confirmed AMI complicated with CKD stage II-IV were divided into two groups according to CHIP sequencing results: CHIP group: Patients diagnosed with AMI combined with CKD stage II-IV underwent PCI and were identifi ed as CHIP carriers by gene targeted sequencing. Non-chip group: Patients diagnosed with AMI combined with CKD stage II-IV underwent PCI and were identified as non-CHIP carriers by gene targeted sequencing. Study endpoint: Primary endpoints: all-cause death, cardiac death, nonfatal myocardial infarction,50% decrease in eGFR, or ESKD. Secondary endpoints: angina pectoris requiring hospitalization, nonfatal stroke, and nonfatal heart failure. Part III: To investigate the effects of CHIP on cardiovascular and renal outcomes in AMI patients with ESRD. Patients with confirmed AMI combined with ESRD were divided into two groups according to CHIP sequencing results: CHIP group: Patients diagnosed with AMI combined with ESRD underwent PCI and were identified as CHIP carriers by gene targeted sequencing. Non-chip group: Patients diagnosed with AMI combined with ESRD underwent PCI and were identified as non-CHIP carriers by gene targeted sequencing. Study endpoint: Primary end points: all-cause death, cardiac death, and nonfatal myocardial infarction. Secondary endpoints: angina pectoris requiring hospitalization, nonfatal stroke, and nonfatal heart failure.
