Analysis of the effectiveness of combined CT angiography, MMP-9, and PAF testing in the assessment of vascular restenosis in acute coronary syndromes after atorvastatin combined with tirofiban therapy.

Background: Acute Coronary Syndrome (ACS) is a very common cardiovascular disease in clinical practice with a very high risk of death. In this study, we observed the effectiveness of CT angiography (CTA), matrix metalloproteinase-9 (MMP-9) and platelet-activating factor (PAF) in the assessment of ACS.

Methods: A total of 124 patients with ACS admitted to our hospital from June 2022 to March 2024 were enrolled as study subjects.

The effects of prophylactic intravenous injection of rhBNP on prognosis in patients with STEMI undergoing PPCI.

This experiment was carried out to observe the application value of recombinant human brain natriuretic peptide (rhBNP) in patients with ST-segment elevation myocardial infarction (STEMI) by primary percutaneous coronary intervention (PPCI), to provide reference for the future treatment of STEMI. In this study, we selected STEMI patients who underwent PPCI treatment in our hospital from October 2019 to December 2021 were selected as the study subjects, of which 46 received intravenous injections of rhBNP (research group), and 36 STEMI patients underwent PPCI (control group). There was no difference in clinical efficacy between the two groups (P>0.
