Key result
Slow coronary flow was associated with significantly higher erythrocyte aggregation amplitude compared to normal coronary arteries (23 vs 15.7 au, p<0.001).
Why the study?
Are there differences in blood viscosity parameters between patients with slow coronary flow and subjects with normal coronary arteries?
Population
56 subjects, including 33 patients with slow coronary flow and 23 subjects with normal coronary arteries.
Design
Case-control

Suggests hemorheological factors may contribute to slow coronary flow; leaves open causality and therapeutic implications.
Case-Control (n=56)
Are there differences in blood viscosity parameters between patients with slow coronary flow and subjects with normal coronary arteries?
Absolute Event Rate: 23% vs 15.7%
p-value: p=< 0.001
Increased erythrocyte aggregation is observed in patients with slow coronary flow, suggesting altered blood rheology may contribute to its pathophysiology.
Ergun-Cagli et al. (2011) conducted a case-control in Slow coronary flow (n=56). Slow coronary flow vs. Normal coronary arteries was evaluated on Aggregation amplitude (p=< 0.001). Slow coronary flow was associated with significantly higher erythrocyte aggregation amplitude compared to normal coronary arteries (23 vs 15.7 au, p<0.001).
