Serum chromogranin A levels are associated with the SYNTAX score in coronary artery disease

Abstract

pancreastatin, a dysglycemic peptide, 3. vasostatin-1, a vasodilator, antiadrenergic and antiangiogenic peptide, 4. serpinin, a proadrenergic peptide.Plasma Cts concentration is a predictor of hypertension. Previous studies have observed elevated serum CgA levels and reduced Cts processing in hypertension. Cts levels have been shown to decrease, while plasma CgA level increases. Metabolic and vascular effects of CgA have been investigated and their role in hypertension and coronary artery disease has been studied. CgA levels have also been found to increase in heart failure, acute myocardial infarction, old age, pulmonary hypertension, and inflammatory diseases [5][6][7][8] .We investigated the relationship between serum CgA levels and SYNTAX scores in patients with coronary artery disease. METHODS Study population and study designPatients who underwent coronary angiography from March 2020 to March 2021 for the diagnosis and treatment of coronary
