Purpose: The slow movement of the distal vascular structures of the contrast substance during coronary angiography is called the coronary slow flow (KYA) phenomenon. Although it has a high morbidity due to recurring chest pain and different ischemic presentations, it is associated with coronary artery disease (myocardial ischemic symptoms, life-threatening arithmies, recurring acute coronary syndrome and sudden heart death). The CHA2DS2-VASc score is a scoring system consisting of a variety of risk factors for tromboembolism. We intended to evaluate the CHA2DS2-VASc score to predict the KYA. Tools and Methods: 3772 patients with a diagnosis of stable angina pectoris (SAP) were scaned backward to the Tokat State Hospital. The study included a total of 155 patients, including 71 patients with an angiographically proven KYA and the control group, with a total of 84 patients with a normal coronary angiography. Patients were divided into two groups: the KYA group (n = 71) and the normal coronary artery group (n = 84). When compared the characteristics of the KYA and control groups, there was no statistically meaningful difference between them in terms of age, body mass index, systolic blood pressure, diastolic blood pressure and gender. According to the results of multi-variable regression analysis, the CHA2DS2-VASc score was an independent determiner (probability ratio [OR]: 1,872, 95% CI: 0,849-1,981, p<0,001) Result: the CHA2DS2-VASc score could be very useful in this regard as a easy-to-apply tool. The CHA2DS2-VASc score may be one of the independent indicators of KYA and can be used to predict the risk of KYA.
