Catestatin was discovered as a potent inhibitor of catecholamine secretion and plays important roles in the cardiovascular system. Our previous study demonstrates a close relationship between catestatin levels and prognosis of ST-elevation myocardial infarction (STEMI). Using the same population, the goal of this study is to investigate the ability of catestatin to predict left ventricular (LV) remodeling in STEMI patients. 72 patients and 30 controls were included. Catestatin was sampled after admission to the emergency room (ER), at day3 (D3), and day7 (D7) after STEMI. Echocardiography was performed at D3 and after 65 months for evaluation of LVEDD, EF, IVS, LVPW, E, A, E', E/A, and E/E'. The changes of these parameters from D3 to 65 months were used to reflect the changes of ventricular structure and function. We found that plasma catestatin levels at D3 were highly correlated with the changes of LVEDD, EF, E, A, E', E/A, as well as E/E'. Patients with higher catestatin levels developed worse ventricular function during the follow-up period. Single-point catestatin was effective to predict LVEDD change. And concurrently increasing catestatin and NT-proBNP levels predicted the highest risk of LV remodeling. This study suggests an important prognostic information of catestatin on LV remodeling.

During pregnancy, significant cardiovascular changes occur to accommodate fetal growth, and catestatin may play a role in these changes. Evidence suggests that catestatin, a pleiotropic sympathoinhibitory peptide, is involved in multiple cardiovascular pathologies, including hypertensive disorders. The objective of this study was to compare serum catestatin levels between first-trimester pregnant women and non-pregnant women, aiming to investigate catestatin's role in blood pressure regulation during early pregnancy.

ESC Heart Fail

Department of Cardiology, Peking University First Hospital, Beijing, China.
Article Synopsis
- The study examines how catestatin, a peptide linked to heart disease, predicts cardiac outcomes in patients with different types of heart failure (HF): HF with reduced ejection fraction (HFrEF), mildly reduced ejection fraction (HFmrEF), and preserved ejection fraction (HFpEF).
- Researchers measured plasma catestatin levels in 228 HF patients and found that its association with cardiac death varied across the different ejection fraction groups during an average follow-up of 52.5 months.
- Elevated plasma catestatin levels were identified as a stronger predictor of cardiac death in patients with HFmrEF/HFpEF than in those with HFrEF, with a significant risk identified at a cut-off level of

Article Synopsis
- Rheumatoid arthritis (RA) is a chronic autoimmune disease that increases the risk of cardiovascular disease (CVD), and this study focused on evaluating new cardiovascular biomarkers in RA patients.
- Researchers assessed 199 RA patients for CVD risk factors, disease activity, and levels of biomarkers like fetuin-A and catestatin, finding significant correlations between these biomarkers and RA parameters.
- While elevated levels of catestatin and fetuin-A showed some associations with rheumatoid factor positivity and other disease markers, no significant links were found to traditional CVD measures like carotid intima-media thickness, indicating a need for more research on these biomarkers' roles in RA.

Preeclampsia (PE) is a unique pregnancy disorder affecting women across the world. It is characterized by the new onset of hypertension with coexisting end-organ damage. Although the disease has been known for centuries, its exact pathophysiology and, most importantly, its prevention remain elusive.
