Abstract

Gonadotropin-releasing hormone agonists were described as anti-angiogenic factors in tumors. Simultaneously they were associated with increased cardiovascular risk in patients treated for prostate cancer, especially in those with preexisting cardiac disease. Studies aiming to elucidate the mechanisms by which androgen deprivation therapy causes cardiovascular effects are rare. We believe that gonadotropin-releasing hormone agonists can impair myocardial angiogenesis. That, in patients with myocardial disease can deepen hypoxia, significantly worsen the condition of the myocardium, and therefore increase the risk of cardiac failure. Careful assessment of the myocardial status and consequent timing and typing of therapy can minimalize the adverse effects. Ideally through close cooperation between cardiologists and oncologists (Fig. 1, Ref. 25). Keywords: angiogenesis, cardiovascular risk, follicle stimulating hormone, GnRH agonist, testosterone.
