Insights
In patients with Non-ST-Elevation Myocardial Infarction (NSTEMI), D-dimer and pro-BNP levels remained stable in the first 12 hours. However, high-sensitivity C-reactive protein (hs-CRP) levels significantly decreased by 12 hours post-admission.
Area of Science:
- Cardiology
- Biomarker Research
Background:
- Elevated high-sensitivity C-reactive protein (hs-CRP), B-type natriuretic peptide (BNP), and D-dimer are linked to adverse outcomes in acute myocardial infarction (AMI).
- Understanding the temporal changes of these biomarkers in Non-ST-Elevation Myocardial Infarction (NSTEMI) is crucial for patient management.
Purpose of the Study:
- To investigate the dynamic changes of D-dimer, hs-CRP, and pro-BNP in patients diagnosed with NSTEMI within the initial 12 hours of hospital admission.
Main Methods:
- Prospective study involving 82 patients with suspected acute coronary syndrome (ACS).
- 40 patients were diagnosed with NSTEMI; the rest had AMI ruled out.
- Blood samples were collected at admission, 6 hours, and 12 hours post-admission for hs-CRP, pro-BNP, and D-dimer analysis using a point-of-care system.
Main Results:
- No significant changes in D-dimer or pro-BNP levels were observed between admission and 12 hours in NSTEMI patients.
- A statistically significant decrease in hs-CRP levels was noted at 12 hours compared to admission values (p=0.04).
Conclusions:
- D-dimer and pro-BNP do not exhibit dynamic changes within the first 12 hours of admission in acute NSTEMI patients.
- hs-CRP levels show a decreasing trend within 12 hours post-admission in NSTEMI patients.
Background:
Elevated levels of high-sensitivity C-reactive protein (hs-CRP), B-type natriuretic peptide (BNP), and D-dimer each are associated with higher rates of death and recurrent ischemic events in patients with acute myocardial infarction (AMI). The aim of this study was to examine the dynamic course of D-dimer, hs-CRP, and pro-BNP in patients with Non-ST-Elevation Myocardial Infarction (NSTEMI).
Methods:
The study group consisted of 82 patients presenting with symptoms suggestive of acute coronary syndrome (ACS). 40 of the patients were diagnosed as NSTEMI and for the rest AMI was ruled out. Blood was drawn at the time of admission, 6 and 12 hours after that. The samples were tested for hs-CRP, pro-BNP and fibrin D-dimer by a quantitative, point-of-care instrument system (Stratus CS).
Results:
D-dimer and pro-BNP did not change between admission and 6 and 12 hours after admission in patients with acute NSTEMI, whereas hs-CRP went down 12 hours after admission compared to the admission value (14.9 +/- 19.4 (mg/mL) v 10.1 +/- 13.5 (mg/mL), p = 0.04).
Conclusions:
There was no dynamic change of D-dimer or pro-BNP during the first 12 hours after admission in patients with acute NSTEMI, whereas hs-CRP decreased 12 hours after admission in these patients.
