In this randomized, double-blind, controlled, parallel group study (ZENITH), 434 essential hypertensives with additional cardiovascular risk factors, uncontrolled by a previous monotherapy, were treated for 18 weeks with zofenopril 30 or 60 mg plus hydrochlorothiazide (HCTZ) 12.5 mg or irbesartan 150 or 300 mg plus HCTZ. Rate of office blood pressure (BP) response (zofenopril: 68% versus irbesartan: 70%;p=0.778) and 24-hour BP response (zofenopril: 85% versus irbesartan: 84%;p=0.781) was similar between the two treatment groups. Cardiac and renal damage was equally reduced by both treatments, whereas the rate of carotid plaque regression was significantly larger with zofenopril. In conclusion, uncontrolled monotherapy treated hypertensives effectively respond to a combination of zofenopril or irbesartan plus a thiazide diuretic, in terms of either BP response or target organ damage progression.

Abstract BACKGROUND Nocturnal hypertension is an important phenotype of abnormal diurnal blood pressure (BP) variability and a known risk marker for target organ damage and cardiovascular events. This study aimed to assess the differential BP-lowering effects of esaxerenone vs. eplerenone on nocturnal BP in hypertensive patients with different nocturnal dipping patterns. METHODS This was a post hoc analysis of the “Esaxerenone (CS-3150) Compared to Eplerenone in Patients with Essential Hypertension” study (NCT02890173), which was a phase 3, multicenter, randomized, controlled, double-blind, parallel-group clinical study conducted in Japan. Ambulatory BP monitoring data were collected. RESULTS Patients (n = 1,001) were randomized to esaxerenone 2.5 mg/day (n = 331) or 5 mg/day (n = 338), or eplerenone 50 mg/day (n = 332). Reductions in nighttime systolic BP (95% confidence interval) were significantly greater with 2.5 and 5 mg/day esaxerenone vs. eplerenone (−2.6 [−5.0, −0.2] and −6.4 mm Hg [−8.8, −4.0], respectively). Esaxerenone significantly reduced nighttime BP from baseline compared with eplerenone in non-dippers with previously uncontrolled BP. In addition, esaxerenone did not markedly alter nighttime BP in extreme dipper patients. In the esaxerenone 5 mg/day group, esaxerenone-induced decreases in nighttime BP were greater than eplerenone-induced decreases in older patients. CONCLUSIONS Esaxerenone may be an effective treatment option for nocturnal hypertension, especially in older patients and those with a non-dipper pattern of nocturnal BP.

The overall goal of this study was to determine race/ethnic differences in the associations between renal ET-1 and indices of blood pressure-related target organ damage in healthy adolescents. The subjects ranged in age between 15-19 years, had no history of any disease, and were not on any prescription medications. The 92 subjects consisted of 48 Caucasians (CA) and 44 African-Americans (AA). The two groups were similar with respect to height, weight, body mass index, blood pressure, ET-1), albumin excretion rate (AER), and left ventricular mass). Results: The CA’s were slightly older 17±1 v 16±1 (p=.02). The protocol was preceded by a 3 day self-selected sodium controlled diet of 250 mEq/day day which the subject picked up each day. The test day began with an echocardiogram for the assessment of left ventricular mass. Next, the subjects were seated for 60 minutes of rest during which the subjects consumed 200 ml of water. This was followed by the collection of a urine sample for the measurement of ET-1 and AER. Overall, ET-1 excretion was correlated with AER (r=.278), LV mass/ht 2.7 (r=.341), and systolic blood pressure (SBP; r=.365; p=.01 for each). The significant overall correlations were the result of significant correlations in AAs for AER (r=.344; p=.05), LV mass/ht 2.7 (r=.520; p=.01), and SBP (r=.645; p=.01) which were not apparent in CA’s. These findings suggest urinary ET-1 contributes to the development of BP-related target organ damage in AA youths prior to the development of increases in blood pressure.
