Keʻano papa hana o ka hana ana i kēia mau ai 'o ka hoike ana o neurohumoral' ole (mea ulu i loko o ka ha awina o ka kallikrein-kinin'ōnaehana, ka hoʻomaikaʻi i ka endothelium-ko iala ololi), a me ka metabolic 'ole (antioxidant hana, mahuahua potasiuma pae, mahuahua pā lonoaʻili o kaʻike ākea nā'aʻaʻa).

Ka lapaʻauʻia no ka vasodilation ua pinepine hoʻohana 'ia i loko o kēia' inikua me ka hana pono, a he maikaʻi pākōlea hopena i loko o nā maʻi o na ipu koko o ke poo a me ka naau, e like me ke alo o ischemic cardiac'aʻaʻa ma ke kaʻina.
