Factors Influencing Time to First Medical Contact in Patients with Acute ST-Segment Elevation Myocardial Infarction: A Retrospective Analysis.

BACKGROUND Exploring the factors that impact the time from symptom onset to first medical contact (S2FMC) is crucial for improving outcomes in elderly patients diagnosed with acute ST-segment elevation myocardial infarction (STEMI). This study conducted a retrospective analysis on 282 patients who underwent emergency percutaneous coronary intervention (PCI) or percutaneous transluminal coronary angioplasty (PTCA) in Guangzhou City District to identify significant factors affecting S2FMC. MATERIAL AND METHODS A retrospective analysis was conducted on 282 patients with STEMI who underwent emergency percutaneous coronary intervention (PCI).

Tirofiban Combined with Fondaparinux for Post-PCI Treatment of Patients with Acute Coronary Syndrome and Mild Renal Insufficiency.

Proper administration of antithrombotic and antiplatelet drugs after percutaneous coronary intervention (PCI) in patients with acute coronary syndrome (ACS) and renal insufficiency is a challenging task. In this study, we utilized Fondaparinux and Tirofiban (either separately or combined) to treat post-PCI patients with ACS and concurrent renal insufficiency. The patients were followed-up for 1 year.

Serum levels of monocyte chemoattractant protein-1 and all-cause and cardiovascular mortality among patients with coronary artery disease.

Background: Monocyte chemoattractant protein-1 (MCP-1) is an important chemokine at multiple phases of atherosclerosis in animals, but human studies are few and inconsistent. The aim of this study is to investigate the association of serum MCP-1 with all-cause and cardiovascular disease (CVD) mortality among coronary artery disease (CAD) patients and determine whether this biomarker can add secondary prognostic value to standard risk predictors.

Methods: MCP-1 was measured at baseline in 1411 CAD patients who were 40-85 years of age.
