Platelet indices like platelet distribution width (PDW) and mean platelet volume (MPV) are elevated in ST-segment elevation myocardial infarction (STEMI). Higher PDW and MPV predict thrombolysis failure in STEMI patients.
Area of Science:
- Cardiology
- Hematology
Background:
- Platelet indices are increasingly recognized as potential biomarkers in cardiovascular diseases.
- Understanding their role in acute myocardial infarction and treatment response is crucial.
Purpose of the Study:
- To investigate the association between platelet indices and stable coronary artery disease (CAD) versus acute ST-segment elevation myocardial infarction (STEMI).
- To determine if platelet indices on admission predict thrombolysis outcomes in STEMI patients.
Main Methods:
- A study involving 260 patients was conducted.
- Platelet indices including mean platelet volume (MPV) and platelet distribution width (PDW) were analyzed.
- Patients were categorized into stable CAD, acute STEMI, and STEMI with thrombolysis success/failure groups.
Main Results:
- White blood cell (WBC) and PDW were significantly higher in STEMI patients compared to stable CAD patients (P < .001).
- WBC and PDW independently predicted acute STEMI.
- MPV and PDW were significantly higher in the thrombolysis failure group versus the success group (P = .021 and P < .001, respectively).
- MPV and PDW independently predicted thrombolysis failure.
Conclusions:
- Elevated PDW is associated with acute STEMI.
- Higher MPV and PDW levels are linked to poorer outcomes with thrombolysis in STEMI patients.
- Platelet indices may serve as valuable prognostic markers in acute coronary syndromes.
