1. Long-term use of leuprolide can lead to decreased estrogen levels, potentially increasing cardiovascular risk by affecting lipid profiles and arterial stiffness.

2. Chronic leuprolide therapy might elevate the risk of heart disease by inducing a hypoestrogenic state, which adversely impacts vascular elasticity and endothelial function.

3. Extended leuprolide usage may contribute to cardiac issues by promoting atherosclerosis due to changes in lipid metabolism and blood pressure regulation.

4. Prolonged administration of leuprolide could heighten cardiovascular risks, including myocardial infarction, by increasing triglycerides and lowering HDL cholesterol levels.
