Thromboembolic risk scores in patients with non-obstructive coronary architecture with and without coronary slow flow: A case-control study

•Coronary slow flow phenomenon (CSFP) is an angiographic finding related to microvascular disease•Individual parameters of thromboembolic risk scores have been linked to CSFP.•The majority of the risk schemes were higher in individuals with CSFP than in those with coronary normal flow.•CHA2DS2-VASc-HS score outperformed all others in determining CSFP for patients with non-obstructive coronary artery architecture.•Among the individual parameters of the CHA2DS2-VASc-HS score, hyperlipidemia was the strongest determinant of CSFP.
