Task: Question Answering
Input (English): Context: Partial adherence to antihypertensive therapy remains a public health challenge and may be associated with increased cardiovascular risk. We quantitatively evaluated cardiovascular risk inherent in partial therapy adherence in spontaneously hypertensive rats with accelerated hypertension.', 'Adult spontaneously hypertensive rats were divided into 5 groups; Group 1 (controls) did not receive any treatment, whereas all other rats (Groups 2-5) were given nitric oxide synthase inhibitor N-nitro-l-arginine methyl ester (L-NAME) to exacerbate hypertension. Group 2 (untreated/nonadherers) was given L-NAME but not antihypertensive medication; Group 3 (Perfect Adherers) was treated daily with candesartan (10 mg/kg); Group 4 was given candesartan 3 times a week, whereas Group 5 received candesartan only during the last 6 days of the 3-week experiment (Partial Adherers). At the end, indices of systemic and regional (kidneys, brain, and heart) hemodynamics, and indices of left ventricular function were determined.', 'Treatment with L-NAME aggravated hypertension, adversely affected target organ blood flows and resistances, and grossly impaired ventricular function. Perfect adherence with candesartan completely reversed the adverse cardiovascular effects of L-NAME intervention. In partial adherers (Groups 4 and 5), arterial pressure decreased and reached control values. However, target organ hemodynamics and heart function showed only slight improvements, if any.\Question: Does partial adherence to antihypertensive therapy fail to achieve full cardiovascular benefits in hypertensive rats?
Output (English): The results demonstrate that partial adherence to therapy reduces arterial pressure, but may not prevent target organ damage. If replicated in humans, these results may have important clinical implications in hypertensive patients.
