Background: Skin tags (STs) are small, pedunculated skin-colored or brown papules that occur around any site where skin folds occur. The literature is short of comprehensive and controlled clinical studies aimed to evaluate the atherogenic risk factors in patients with STs. Aim of Work: The aim of this study is to evaluate the impact of age, STs, metabolic syndrome (METs), body mass index (BMI), and smoking on homocysteine (Hcy), endothelin-1 (ET-1), high-sensitive C-reactive protein (Hs-CRP), and on cardiovascular diseases. Materials and Methods: This study included 30 cardiac patients without STs, 30 non-cardiac patients with STs, and 30 healthy controls with neither heart disease nor STs. History of smoking, measurement of height, weight, BMI, waist circumference (WC), blood pressure, STs number, color, acanthosis nigricans, estimation of serum level of fasting glucose, triglycerides (TGs), cholesterol, high-dense lipoproteins (HDL), Hcy, ET-1, Hs-CRP, and the presence of the METs were elicited in the three groups. Results: Regarding the Hcy, ET-1, and Hs-CRP, the cardiac-STs group showed the highest levels and the control group showed the least ( P < 0.001). The percents of patients with METs were 56.7% in the cardiac-STs, 40% in the non-cardiac-STs, and 0% in the control group ( P < 0.001). Mean BMI exceeded the limit of obesity in the cardiac-STs group (30.9 ± 3.9) and the non-cardiac-STs group (32.6 ± 6) and was normal in the control group (24.7 ± 2.8). Hyperpigmented STs were present in 66.7% of the cardiac-STs group. Multivariate regression analysis for the independent effectors on Hcy level were the presence of STs ( P < 0.001), METs ( P = 0.001), and BMI ( P = 0.024). Regarding ET-1, the effectors were the presence of STs and METs ( P = 0.032). For Hs-CRP, effectors were the presence of STs ( P < 0.001) and smoking ( P = 0.040). Multivariate logistic regression of the predictors of cardiac disease showed that the independent predictors of the occurrence of cardiac disease were BMI ( P < 0.001), STs ( P = 0.002), and METs ( P = 0.037). Conclusion: STs may act as a physical sign of underlying raised cardiac atherogenic factors. This may indicates an ongoing risk on coronary circulation which may indicate further corrective action, hopefully early enough. The association of ST with obesity and METs represents a Bermuda Triangle that act against the heart.
