Varicose veins have no effect on the heart because the blood from varicose veins will stagnate in the varicose veins and less venous blood will enter the heart, but it will not have much effect on the heart. On the contrary if there is a problem with the heart, such as heart failure, the patient’s varicose veins will be aggravated because of heart failure, the ejection function of the heart is reduced, so the blood tends to stagnate in the surrounding tissues, the varicose veins to blood increase, the symptoms of varicose veins will be aggravated and the varicose veins will be thickened. So varicose veins have no effect on the heart, but if there are more varicose veins, they tend to form thrombosis or rupture and bleed, and need to be actively prevented.
