Coronary collateral circulation to the severely stenotic left anterior descending artery was not found to have an improving effect on left ventricular systolic function. In contrast with the previous studies demonstrating the coronary collateral circulation-associated preservation of left ventricular systolic function, presence of coronary collateral circulation was found to accompany or be associated with impairment of left ventricular systolic function. The grade of coronary collateral circulation was also found to be positively correlated with the severity of left ventricular systolic dysfunction. Further research on larger patient populations based on a long-term follow-up is warranted to investigate this issue.

Background and Purpose Collaterals at angiography before endovascular therapy were analyzed to ascertain the effect on a novel end point of successful revascularization without symptomatic hemorrhage in the Solitaire FR With the Intention for Thrombectomy (SWIFT) study. Methods Collateral grade (American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology) on baseline angiography was independently assessed, blind to other data, with statistical analyses delineating the relationship with clinical, laboratory, and imaging parameters. Results Angiographic data on collaterals were available in 119 of 144 subjects (mean age, 67±12 years; 52% woman; median National Institutes of Health Stroke Scale, 18 [range, 8–28]). Worse collaterals were noted in subjects with elevated baseline blood glucose (P=0.013) and those with elevated baseline systolic blood pressure (P=0.039). Multivariate predictors of partial or worse collaterals included absence of prior hypertension (odds ratio, 4.049, P=0.012), smoking history (odds ratio, 3.822; P=0.013), and higher blood glucose (odds ratio, 1.017; P=0.022). Collaterals were strongly related to Alberta Stroke Program Early CT Score (ASPECTS) at baseline (0–1: median 8 [3–10]; 2–9 [5–10]; 3–9 [7–10]; 4–9 [8–10]; P<0.001) and 24 hours (0–1: median 1 [0–5]; 2–6 [0–10]; 3–8 [0–10]; 4–8 [4–8]; P<0.001). Better collaterals were linked with Thrombolysis in Cerebral Infarction 2b/3 reperfusion (P=0.019), better median National Institutes of Health Stroke Scale at day 7/discharge (P<0.001), and better day 90 modified Rankin Scale (P<0.001). Better collateral grade was associated with successful revascularization without symptomatic hemorrhage, mean 2.3 (95% confidence interval, 2.1–2.5) versus 1.9 (95% confidence interval, 1.7–2.2), P=0.021. Conclusions Better collaterals were associated with lower glucose, lower blood pressure, smaller baseline infarcts in SWIFT, and greater likelihood of successful revascularization without hemorrhage and good clinical outcomes.

“…Bang et al 11 also found an association between smoking status and low HIR. Studies have suggested that long-term smoking-induced atherosclerosis leads to increased collateralization, 18 which may explain this observed phenomenon.…”

BACKGROUND AND PURPOSE:Hyperintense vessels on baseline FLAIR MR imaging of patients with ischemic stroke have been linked to leptomeningeal collateralization, yet the ability of these to maintain viable ischemic tissue remains unclear. We investigated whether hyperintense vessels on FLAIR are associated with the severity of hypoperfusion and response to thrombolysis in patients treated with intravenous tissue-plasminogen activator.
