Insights
Serum C-reactive protein (CRP) levels are significantly elevated in acute coronary syndrome (ACS) patients compared to healthy individuals. CRP levels also increase post-intervention in ACS patients requiring management.
Area of Science:
- Cardiovascular Medicine
- Inflammation Biology
Background:
- Inflammation is central to atherosclerosis, the primary cause of acute coronary syndrome (ACS).
- C-reactive protein (CRP), an inflammatory marker, is synthesized post-myocardial infarction, exacerbating plaque inflammation.
Purpose of the Study:
- To investigate serum C-reactive protein (CRP) levels in patients with acute coronary syndrome (ACS).
- To compare CRP levels between ACS patients and healthy controls.
- To assess CRP level changes in ACS patients undergoing different management strategies.
Main Methods:
- High-sensitivity C-reactive protein (hs-CRP) measured via immunoturbidimetry.
- Study included 100 ACS patients and 50 healthy controls.
- ACS patients were categorized into conservative or interventional management groups.
Main Results:
- ACS patients exhibited significantly higher serum CRP levels (11.90 mg/L) than controls (2.30 mg/L) upon admission.
- CRP levels progressively increased in ACS patients over 24 hours.
- Patients undergoing interventional management showed markedly higher CRP levels (115.90 mg/L) versus conservative management (22.28 mg/L).
Conclusions:
- Serum CRP levels are significantly elevated in acute coronary syndrome (ACS) patients.
- Higher CRP levels are observed in ACS patients receiving interventional management compared to conservative care.
Background:
Inflammation plays a key role in the initiation and progression of atherosclerosis, the most common cause of acute coronary syndrome. C-reactive protein (CRP) that enhances plaque inflammation is synthesized six hours after myocardial infarction.
Methods:
High sensitivity C-reactive protein was measured by Immunoturbiditory method in 50 healthy controls and 100 patients of acute coronary syndrome on conservative or interventional management.
Results:
Serum C-reactive protein levels [mg/L +/- SEM] at the time of admission were significantly raised in patients of acute coronary syndrome (11.90 +/- 2.30) as compared to controls (2.30 +/- 0.18) and further increased progressively during 24 hours of follow up period. C-reactive protein levels also increased significantly in patients who underwent interventional management (115.90 +/- 7.73) as compared to those who were on conservative management (22.28 +/- 5.54).
Conclusion:
Serum C-reactive protein levels were found to be significantly raised in patients with acute coronary syndrome as compared to controls. In addition, patients undergoing interventional management had higher C-reactive protein levels, post intervention, as compared to those on conservative management.
