Insights
Platelet count (PC), mean platelet volume (MPV), and platelet distribution width (PDW) were significantly elevated in acute coronary syndrome (ACS) patients compared to healthy controls. These findings suggest larger platelets may indicate higher risk for coronary events.
Area of Science:
- Cardiology
- Hematology
- Clinical Diagnostics
Background:
- Acute coronary syndrome (ACS) is a major cause of cardiovascular mortality.
- Platelets play a critical role in atherothrombosis, the underlying mechanism of ACS.
- Routine hematological parameters may offer insights into ACS pathophysiology.
Purpose of the Study:
- To investigate the relationship between platelet indices and acute coronary syndrome.
- To compare platelet count (PC), mean platelet volume (MPV), and platelet distribution width (PDW) in ACS patients versus healthy controls.
Main Methods:
- A cross-sectional descriptive study involving 50 ACS patients and 50 age/sex-matched healthy controls.
- Diagnosis of ACS based on clinical history, ECG, and cardiac biomarkers.
- Platelet parameters (PC, MPV, PDW) measured using an automated hematological analyzer.
Main Results:
- All measured platelet indices (PC, MPV, PDW) were significantly higher in ACS patients (mean PC: 352.2×10⁹/L, MPV: 13.9fL, PDW: 15.6fL) compared to controls (mean PC: 256.2×10⁹/L, MPV: 8.1fL, PDW: 10.5fL).
- Statistical analysis revealed a significant difference (p < 0.05) in the mean values of these indices between the groups.
- Larger platelets are associated with increased hemostatic activity.
Conclusions:
- Elevated platelet count, MPV, and PDW are significant indicators in patients with acute coronary syndrome.
- These findings suggest that increased platelet indices may serve as a risk factor for coronary thrombosis and events like myocardial infarction and unstable angina.
- Identifying patients with larger platelets via routine hematological analysis could aid in preventive treatment strategies.
Abstract:
This cross sectional descriptive study was carried out in the Department of Cardiology, Mymensingh Medical College Hospital from July 2015 to December 2015, included 50 patients admitted with acute coronary syndrome diagnosed on the basis of history, typical anginal type of chest pain, characteristic electrocardiographic changes and increased cardiac biomarkers. Platelet count (PC), Mean platelet volume (MPV) and platelet distribution width (PDW) were measured using automated hematological analyzer and compared them with 50 age and sex matched healthy controls. All platelet parameter indices - platelet count (PC), mean platelet volume (MPV) & platelet distribution width (PDW) - were significantly raised in patients with ACS. In patients with ACS the mean values of platelet count, MPV & PDW were 352.2×10⁹/L), 13.9fL & 15.6fL, respectively; while in normal healthy control the mean values of these indices were 256.2×10⁹/L), 8.1fL & 10.5fL, respectively. Statistically significant difference in mean values of these indices was found (p value <0.05). Larger platelets are haemostatically more active and are a risk factor for developing coronary thrombosis and subsequent acute coronary events (myocardial infarction and unstable angina). Patients with larger platelets can easily be identified during routine hematological analysis and could possibly benefit from preventive treatment.
