Differences in the effects of contrast agents on kidney injury and inflammatory response between diabetic and non-diabetic patients and their clinical significance.

With the increasing incidence of coronary heart disease (CHD), contrast-associated nephropathy (CAN) caused by contrast agents required in coronary angiography has gradually become a clinical concern that needs to be solved urgently. At present, CAN has become one of the most common causes of hospital-acquired acute kidney injury, which seriously affects the prognosis and health of patients. How to effectively identify high-risk CAN patients and prevent the occurrence of CAN has become a hotspot of clinical research.

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.
