Background: Primary coronary slow flow phenomenon (PCSFP) is a clinical entity that causes attacks of mild to severe chest pain. It is characterized by delayed coronary vessel opacification in the absence of epicardial stenosis. This work aimed for the assessment of predictors, clinical presentation, and angiographic profile of PCSFP. Subjects and Methods: This cross-sectional case–control study was done between February 2019 and January 2020, including 150 patients who presented by ST-segment myocardial infarction, non-ST segment myocardial infarction, unstable angina, chronic coronary syndrome, or atypical chest pain. The patients were divided into two groups: group 1: consisted of 100 patients who had PCSFP and Group 2: consisted of 50 patients who had normal coronary flow (NCF). Results: PCSFP was significantly more prevalent in young male patients. Among the traditional risk factors, there was significantly more prevalence of hypertension (63.0% vs. 28.0%, P = 0.001), obesity (body mass index ≥30 kg/m2 (47.0% vs. 4.0%, P = 0.001), and history of smoking (66.0% vs. 40.0%, P < 0.002) in PCSFP patients as compared to NCF patients. Triglyceride (TG), cholesterol, low-density lipoprotein, high-sensitivity C-reactive protein (hs-CRP), and hemoglobin all were higher in patients with PCSFP. Low high-density lipoprotein levels were associated with PCSFP. In multivariable analysis, PCSFP was significantly independently associated with male sex, high TG, cholesterol, and hs-CRP. TG (odds ratio [OR]: 14.427, 95% confidence interval [CI]: 3.514–59.226) and cholesterol (OR: 11.739, 95% CI, 2.439–56.513) are the strongest independent predictors for PCSFP. Conclusion: PCSFP is more common in young smoker males, is associated with hypertension, obesity, high hs-CRP, TG, and cholesterol levels. High cholesterol and TG and male sex are the strongest risk factors for PCSFP. Furthermore, inflammation plays an important factor in the pathogenesis of PCSFP due to the association of high hs-CRP level in those patients.
