Insights
Elevated mean platelet volume (MPV) is linked to slow coronary flow (SCF), a condition causing ischemia. Higher MPV independently predicts both the presence and severity of SCF in patients with suspected heart disease.
Area of Science:
- Cardiology
- Hematology
- Vascular Biology
Background:
- Slow coronary flow (SCF) is a condition characterized by delayed opacification of coronary arteries, potentially leading to ischemia and sudden cardiac death.
- Understanding the association between SCF and cardiovascular risk factors is crucial for risk stratification and management.
Purpose of the Study:
- To investigate the relationship between the presence and extent of slow coronary flow (SCF) and various cardiovascular risk factors and hematologic indices.
- To identify independent predictors of SCF presence and severity.
Main Methods:
- Retrospective evaluation of 57 SCF patients and 90 age- and gender-matched controls who underwent coronary angiography.
- Automated complete blood count (CBC) analysis for baseline hematologic indices, including mean platelet volume (MPV).
- Assessment of cardiovascular risk factors and medications in both groups.
Main Results:
- Diabetes, hypercholesterolemia, smoking, hemoglobin levels, and mean platelet volume (MPV) were independent correlates of SCF presence.
- Elevated MPV was significantly associated with the presence of SCF (OR = 2.52, p = 0.001).
- MPV was also identified as an independent correlate of the extent of SCF (OR = 2.13, p = 0.03).
Conclusions:
- Elevated baseline mean platelet volume (MPV) is an independent predictor for both the presence and extent of slow coronary flow (SCF).
- MPV may serve as a valuable hematologic marker in assessing patients with or at risk for SCF.
Background:
Slow coronary flow (SCF) is characterized by delayed opacification of epicardial coronary vessels. SCF can cause ischemia and sudden cardiac death. We investigated the association between presence and extent of SCF, and cardiovascular risk factors and hematologic indices.
Methods:
In this study, 2467 patients who received coronary angiography for suspected or known ischemic heart disease were retrospectively evaluated between April 2009 and November 2010. Following the application of exclusion criteria, our study population consisted of 57 SCF patients (experimental group) and 90 patients with age- and gender-matched subjects who proved to have normal coronary angiograms (control group). Baseline hematologic indices were measured by the automated complete blood count (CBC) analysis. The groups were evaluated for cardiovascular risk factors and medications. Patients were categorized based on the angiographic findings of vessels with or without SCF. Moreover, patients with SCF were divided into subgroups relative to the extent of SCF.
Results:
Among the 147 patients (mean age 52.7 ± 10.0, 53.7% male), mean platelet volume (MPV) ranged from 6.5 fL to 11.7 fL (median 7.9 fL, mean 8.1 ± 0.8 fL). Diabetes (OR = 3.64, 95% CI 1.15-10.43, p = 0.03), hypercholesterolemia (OR = 4.94, 95% CI 1.99-12.21, p = 0.001), smoking (OR = 3.54, 95% CI 1.43-8.72, p = 0.006), hemoglobin (OR = 1.69, 95% CI 1.22-2.36, p = 0.002), and MPV (OR = 2.52, 95% CI 1.43-4.44, p = 0.001) were found to be the independent correlates of SCF presence. Only MPV (OR = 2.13, 95% CI 1.05-4.33, p = 0.03) was identified as an independent correlate of extent of SCF.
Conclusions:
Elevated baseline MPV value was found to be an independent predictor of the presence and extent of SCF.
