The endocrine system is a network of glands and organs that produce, store, and secrete hormones. It influences many aspects of the cardiovascular system, which include the heart and blood vessels. While hormones play a necessary role in maintaining healthy cardiovascular function, very high levels of some can contribute to cardiovascular disease.
Certain hormones can increase blood pressure and raise levels of lipids (blood fats—cholesterol and triglycerides). Hypertension (high blood pressure) and dyslipidemia (abnormal lipid levels) are risk factors for heart disease and stroke.
