Insights
In patients treated with pitavastatin, elevated inflammatory markers like hs-CRP, IL-6, and TNF-α are linked to myocardial injury. Monitoring these markers can help improve patient prognosis and cardiovascular outcomes.
Area of Science:
- Cardiology
- Biochemistry
- Clinical Medicine
Background:
- Inflammation is a key driver of atherosclerosis and myocardial injury.
- Research on pitavastatin's impact on inflammation and myocardial injury markers is limited.
Purpose of the Study:
- To investigate the correlation between inflammatory marker levels and myocardial injury indices in patients receiving pitavastatin.
- To identify independent risk factors for myocardial injury in this patient cohort.
Main Methods:
- Retrospective study of 100 pitavastatin-treated patients, stratified into myocardial injury and non-myocardial injury groups.
- Assessed inflammatory markers (hs-CRP, IL-6, TNF-α, MCP-1, FIB) and myocardial injury indices (cTnI, CK-MB, LDH, Mb).
- Employed Spearman's correlation and logistic regression analyses to determine relationships and risk factors.
Main Results:
- Patients with myocardial injury exhibited significantly higher levels of inflammatory markers and myocardial injury indices compared to the non-injury group.
- Elevated hs-CRP, IL-6, and TNF-α were identified as independent risk factors for myocardial injury.
- A positive correlation was observed between inflammatory markers and myocardial injury indices.
Conclusions:
- Inflammatory markers are significantly correlated with myocardial injury in patients undergoing pitavastatin treatment.
- Monitoring hs-CRP, IL-6, and TNF-α levels can aid in predicting and managing myocardial injury.
- These findings suggest potential therapeutic targets for improving cardiovascular outcomes in pitavastatin-treated patients.
Background:
Inflammation drives atherosclerosis and myocardial injury; pitavastatin's effect on related markers lacks research.
Objectives:
For the purpose of ascertaining the link between inflammatory marker levels and myocardial injury indices in patients undergoing pitavastatin treatment.
Methods:
A retrospective study screened 105 pitavastatin-treated patients at the Affiliated Hospital of Guizhou Medical University (January 2022-December 2024). After exclusion criteria application, 100 patients were recruited and stratified into the myocardial injury group (n=32) and non-myocardial injury group (n=68). The primary outcome measures included inflammatory markers, high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), monocyte chemoattractant protein-1 (MCP-1) and fibrinogen (FIB). The secondary outcome measures included lipid profiles such as total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and the incidence of major adverse cardiovascular events (MACE); as well as myocardial injury indices: cardiac troponin I (cTnI), creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH) and myoglobin (Mb). Spearman's correlation analysis was executed to assess the correlation between baseline inflammatory markers and myocardial injury indices. Logistic regression analysis was adopted to pinpoint independent risk factors for myocardial injury.
Results:
Logistic regression analysis indicated that the baseline characteristics of the two groups were well matched (all P>0.05). Hs-CRP, IL-6, TNF-α, MCP-1, FIB, cTnI, CK-MB, LDH, Mb, TC and LDL-C in the myocardial injury group were higher than those in the non-myocardial injury group (all P<0.05). The incidence of MACE in the myocardial injury group was higher than that in the non-myocardial injury group (P=0.002). Spearman's correlation analysis revealed that hs-CRP, IL-6, TNF-α, MCP-1 and FIB suggested positive correlation with cTnI, CK-MB, LDH and Mb (all P<0.001). Logistic regression analysis suggested that elevated hs-CRP, IL-6 and TNF-α levels are independent risk factors for myocardial injury in patients receiving pitavastatin treatment.
Conclusion:
In pitavastatin-treated patients, inflammatory markers correlate with myocardial injury; monitoring hs-CRP, IL-6, TNF-α improves prognosis.
