Key result
Coronary slow flow was associated with elevated reticulated platelet levels compared to normal coronary anatomy in stable coronary artery disease, though not statistically significant (p=0.105).
Why the study?
Coronary slow flow remains a clinical enigma, and its potential relationship with reticulated platelets in stable coronary artery disease patients is not established.
Are reticulated platelet levels associated with the coronary slow flow phenomenon in patients with stable coronary artery disease?

Are reticulated platelet levels associated with the coronary slow flow phenomenon in patients with stable coronary artery disease?
p-value: p=0.105
Reticulated platelet levels are not significantly associated with the coronary slow flow phenomenon in patients with stable coronary artery disease.
Should not change clinical management in stable CAD; leaves open a potential reticulated platelet link requiring larger studies.
Objectives The coronary slow flow (CSF) phenomenon remains a clinical enigma, characterized by delayed opacification of coronary vessels despite angiographically normal or nearly normal arteries. This cross-sectional study explores the potential relationship between reticulated platelets (RPs) and CSF in stable coronary artery disease patients. Methods A total of 200 participants, meeting specific inclusion and exclusion criteria, underwent coronary angiography. Reticulated platelet levels were measured using Sysmex series hematology analyzers. Demographic data, laboratory parameters, and coronary flow velocities were assessed. Results The study comprised 100 individuals with CSF and 100 with normal coronary anatomy. The CSF group exhibited higher rates of diabetes (35 vs. 22 %, p=0.017) and smoking (62 vs. 45 %, p=0.021). Reticulated platelet rates were elevated in the CSF group. However, statistical significance was not reached (p=0.105). Conclusions This study provides insights into the interplay between reticulated platelets and the CSF phenomenon in stable coronary artery disease. Although reticulated platelet levels did not emerge as a major predictor for CSF in this stable phase, the findings contribute to ongoing efforts to understand the multifaceted mechanisms underlying CSF.

Erdem et al. (2024) conducted a cross-sectional in stable coronary artery disease (n=200). Coronary slow flow vs. Normal coronary anatomy was evaluated on Reticulated platelet levels (p=0.105). Coronary slow flow was associated with elevated reticulated platelet levels compared to normal coronary anatomy in stable coronary artery disease, though not statistically significant (p=0.105).
