“…The study reported an insignificance difference between the two groups regarding the age, the gender, the BMI, and hypertension. In contrast to our findings, Huang et al [12] study included patients with normal epicardial arteries angiographically (145 patients with CSFP and 145 normal controls). Clinical data and laboratory indices were collected and analyzed prior to coronary angiography using peripheral venous blood samples.…”

Background: Patients with coronary slow flow phenomenon (CSFP) exhibit the following characteristics: Predominantly middle-aged males, the majority have mixed pattern angina, persistent chest pain sensations after therapy, and many have had repeated invasive and non-invasive examinations. Objectives: Our study aimed to determine the base of non-invasive predictors of coronary slow flow phenomenon in patients presenting with chronic coronary syndrome. Patients and Methods: This a case-control study included 100 participants of suspected coronary artery disease were divided into two groups matched in age and sex group I: 50 patients with primary CSFP and group II: 50 patients with normal coronary angiography. Each patient was undergoing to demographic data taking, physical investigation, good hydration, restrict fasting hours requested for coronary angiography, 12 lead-Electrocardiogram (ECG)s were obtained for each patient at rest, laboratory parameters, coronary angiography, treadmill exercise ECG, transthoracic echocardiography to assess the thickness of the left ventricle’s (LV) wall, its interior dimensions, as well as the LV’s ejection fraction (EF) using M-mood method and the aortic propagation velocity. Results: male sex and the Canadian Cardiovascular Society Angina grade’s (CCSA) class 3 were significantly decreased in group I compared to group II and male sex, Diabetes mellitus (DM), smoker and CCSA class 4 were substantially increase in group I compared to group II (P <0.05). P wave max, P Wave dispersion (PWd), corrected QT dispersion (QTcd) at resting ECG, T wave inversion and ST Waves segment depression at stress ECG were significantly increase in group I compared to group II. QTc min was significantly lower in group I compared to group II (P <0.05). LA diameter was significantly increased in group I than group II. Aortic propagation velocity was significantly decreased in group I than group II (P <0.05). Hematocrit, total leucocytic count, mean platelet volume and High-sensitivity C-reactive protein (hsCRP) were significantly increase group I compared to group II (P <0.05). Conclusions: Patients suspected of having a coronary artery disease who are diagnosed with coronary slow flow, male sex, dilated LA, CCSA class 3 or 4, elevated hematocrit value, elevated total leucocytic count, increased mean platelet volume, increased HsCRP, P max, PWd, QTcd, T wave inversion, ST segment depression, and decreased aortic propagation were statistically higher in CSFP patient compared to controls.

“…16 Increasing evidence indicates that patients with CSFP are prone to atherosclerosis and obstructive CAD. 43,44 Consistent with these findings, the MAPH score was identified as a significant indicator in distinguishing both the presence and the severity of CAD, exhibiting better diagnostic performance than LSR and HSR. Moreover, the regression model incorporating the MAPH score explained a higher variance of CAD compared to the regression models that included the LSR and HSR indices.…”

Aims: Growing evidence suggests that blood viscosity plays a crucial role in both the development and acceleration of atherosclerosis. In this study, aimed to investigate the diagnostic performance of the mean platelet volume-age-total protein-hematocrit (MAPH) score, a new index for blood viscosity, in predicting the presence and severity of CAD in patients with suspected coronary artery disease (CAD). Methods: We retrospectively evaluated 431 patients who underwent coronary angiography. SYNTAX score (SS) were divided into 3 groups; low group (

“…Xia et al (25) concluded that coronary slow flow may be equally prevalent between males and females and a study by Huang et al (26) concluded that there is no substantial difference in age, smoking, hypertension, DM as well as blood pressure measurements between patients having coronary slow flow and control patients.…”

Background: QT dispersion is the interval between the longest QT (QTmax) as well as the shortest QT (QTmin) recorded on a surface 12-lead electrocardiogram. It has a predictive value for ventricular arrhythmias including patients with ischemic heart diseases as well. Coronary slow flow has been always an ambiguous entity on the scale of ischemic heart disease. The predictive value of QT dispersion for coronary slow flow may add a non-invasive tool for the identification of these patients. Objectives: Evaluation of QT dispersion in the prediction of coronary slow flow phenomena in patients having stable coronary artery disease experiencing coronary angiography. Results: In patients having coronary slow flow, QTc dispersion is prolonged. Conclusion:In patients having stable coronary artery disease, QTc dispersion can be employed as a simple non-invasive approach for predicting coronary slow flow; coronary slow flow is not necessarily associated with a benign course, as evidenced by the fact that these patients exhibit a prolonged QT dispersion.
