GALNT4 in Patients With Acute Coronary Syndrome

Changes of GALNT4 and the Relationship With PSGL-1on Monocytes and Hs-CRP in Blood of Patients With Coronary Heart Disease

The expression of GALNT4 in blood with acute coronary syndrome

Study Overview

• Status: Completed
• Conditions: Acute Coronary Syndrome
• Intervention / Treatment: Diagnostic test: expression of GALNT4

Detailed Description

Emerging evidences have linked GALNTs to cardiovascular disease or susceptibility to CAD.GALNT4, a member of the GalNAc-Ts family,contributes to the initiation of O-linked. Polymorphisms in GALNT4 have been linked with incidence of MI in an Irish population, probably that O-glycosylation of PSGL-1 by GalNAc-T4 may be important for many P-selectin mediated inflammation.However, there is few relevant studies about the expression of GALNT4 in patients with acute coronary syndrome.This study valuates the expression of GALNT4 in patients with acute coronary syndrome.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
STEMI; The study population consists of 20 patients with ST-elevated acute myocardial infarction (STEMI,n = 20) who are admitted within 24 hours after chest pain attack. They will all undergo coronary angiography. The diagnosis is made according to American Heart Association (AHA, 2014 and 2015) guidelines. Patients who had autoimmune diseases, malignancies, chronic or acute infections, severe heart failure (NYHA class 3 and 4) and advanced liver or renal diseases are excluded.	Diagnostic test: expression of GALNT4; Blood is obtained into ethylenediaminetetraacetic acid（EDTA） tubes from all subjects via antecubital venepuncture and the total RNA was extracted from blood.Realtime PCR was performed to measure the expression of GALNT4.
NSTE-ACS; The study population consists of 30 patients with non-ST elevated acute myocardial infarction (NSTE-ACS,n=30) who are admitted within 24 hours after chest pain attack. They will all undergo coronary angiography. The diagnosis is made according to American Heart Association (AHA, 2014 and 2015) guidelines. Patients who had autoimmune diseases, malignancies, chronic or acute infections, severe heart failure (NYHA class 3 and 4) and advanced liver or renal diseases are excluded.	Diagnostic test: expression of GALNT4; Blood is obtained into ethylenediaminetetraacetic acid（EDTA） tubes from all subjects via antecubital venepuncture and the total RNA was extracted from blood.Realtime PCR was performed to measure the expression of GALNT4.
SAP; The study population consists of 30 patients with stable angina pectoris (SAP, n = 30). The diagnosis is made according to the criteria of the American Heart Association (AHA, 2014 and 2015). Patients who had autoimmune diseases, malignancies,chronic or acute infections, severe heart failure (NYHA class 3and 4) and advanced liver or renal diseases are excluded.	Diagnostic test: expression of GALNT4; Blood is obtained into ethylenediaminetetraacetic acid（EDTA） tubes from all subjects via antecubital venepuncture and the total RNA was extracted from blood.Realtime PCR was performed to measure the expression of GALNT4.
CONTROL; 20 age and body mass index matched healthy subjects with neither coronary artery disease nor any of the components of the metabolic syndrome are studied as Normal group	Diagnostic test: expression of GALNT4; Blood is obtained into ethylenediaminetetraacetic acid（EDTA） tubes from all subjects via antecubital venepuncture and the total RNA was extracted from blood.Realtime PCR was performed to measure the expression of GALNT4.
