Careful investigation reveals that while oxidant production does occur during cardiac surgery in patients with chronic ischemic heart disease, cardiac oxidative stress may not progress through membrane damage and irreversible injury.

To study the efficacy of a treatment strategy for the management of hypertensive urgencies, the authors evaluated 549 patients admitted to the emergency department. They were first assigned to a 30‐minute rest period, then a follow‐up blood pressure measurement was carried out. Patients who did not respond to rest were randomly assigned to receive an oral dose of an antihypertensive drug with different mechanisms of action and pharmacodynamic properties (perindopril, amlodipine, or labetalol), and blood pressure was reassessed at 60‐ and 120‐minute intervals. A satisfactory blood pressure response to rest (defined as postintervention systolic blood pressure <180 mm Hg and diastolic blood pressure <110 mm Hg, with at least a 20 mm Hg reduction in basal systolic blood pressure and/or a 10‐mm Hg reduction in basal diastolic blood pressure) was observed in 31.9% of population. Among nonresponders, 79.1% had a satisfactory blood pressure response to the antihypertensive drug treatment in a 2‐hour average follow‐up period. No major adverse events were observed. This treatment strategy, based on standardized rest as an initial step and different antihypertensive drugs, can be effective and safe for the management of patients with hypertensive urgencies.

In young ADPKD patients, normal levels of UACR suggest that renal interstitium is comparable to that in healthy subjects and indicate an absence of subtle atherosclerotic changes in the carotid arteries. Likewise, early renal and vascular changes may be present at UACR below the levels defined as microalbuminuria.
