Considering the patient's hypertension managed with lisinopril and the presence of stress and social isolation, which mechanism best explains how lisinopril may help mitigate stress-related blood pressure elevations?
Lisinopril increases the release of endorphins, promoting relaxation and reducing stress. Lisinopril inhibits the conversion of angiotensin I to angiotensin II, reducing vasoconstriction and blood pressure, which can be elevated by stress. Lisinopril directly decreases heart rate, which helps lower stress-induced anxiety. Lisinopril acts as a sedative, reducing the perception of stress and anxiety.
