Clinical and coronary angiographic characteristics of patients with coronary slow flow

Abstract

In this study we demonstrated that patients with SCF had a significant metabolic disarrangement compared to the control group. Patients with SCF have a high incidence of metabolic syndrome which leads to development of coronary microvascular dysfunction via several mechanisms.

Assessment of the relationship between a narrow fragmented QRS complex and coronary slow flow

“…CSF has been demonstrated to be more common in males, smokers, and in individuals with hyperlipidemia, metabolic syndrome, or obesity [18]. However, we were unable OR -odds ratio; CI -confidence interval; GFR -glomerular filtration rate; BP -blood pressure a significant independent predictor for a narrow fQRS complex, after adjustment for other parameters that univariate analysis had identified as to show any difference between the CSF and control groups in terms of age, gender, or other risk factors for CAD, including hypertension, diabetes, dyslipidemia, family history, and smoking; the exception was BMI, which was found to be higher in patients with CSF, consistently with some other previous studies [19,20].…”

Assessment of the relation between initial culprit vessel patency in acute ST-elevation myocardial infarction and endothelial function

“…Slow coronary flow, which is defined as delayed coronary opacification in the absence of obstructive coronary lesions, is often the result of microvascular constriction that is caused by endothelial dysfunction 35 . Male sex, younger age, smoking, high BMI, and features of metabolic syndrome were found to be associated with slow coronary flow [35][36][37] .…”

Pharmacological Management of Cardiac Syndrome Y: A Focused Review

“…Patients affected by the CSFP are typically young males who are smokers and presenting with a clinical picture of an acute coronary syndrome [29]. Only Yilmaz et al, found an association with the metabolic syndrome while Hawkins et al found an association with obesity [30]. It is very prudent, before diagnosing a patient as having the CSY, to rule out secondary causes of angiographic slow flow, examples include: Coronary ectasia, coronary spasm, coronary stenosis, inadvertent air embolism, residual infarct related stenosis and left ventricular hypertrophy causing microvascular dysfunction [9,12,31].…”
