Abstract
Masked uncontrolled hypertension (MUCH) in treated hypertensive patients is defined as controlled automated office blood pressure (BP; <135/85 mm Hg) in-clinic but uncontrolled out-of-clinic BP by ambulatory BP monitoring (awake [daytime] readings ≥135/85 mm Hg or 24-hour readings ≥130/80 mm Hg). To determine whether MUCH is attributable to antihypertensive medication nonadherence. One hundred eighty-four enrolled patients were confirmed to have controlled office BP; of these, 167 patients were with adequate 24-hour ambulatory BP recordings. Of 167 patients, 86 were controlled by in-clinic BP assessment but had uncontrolled ambulatory awake BP, indicative of MUCH. The remaining 81 had controlled in-clinic and ambulatory awake BP, consistent with true controlled hypertension. After exclusion of 9 patients with missing 24-hour urine collections, antihypertensive medication adherence was determined based on the detection of urinary drugs or drug metabolites by high-performance liquid chromatography-tandem mass spectrometry. Of the 81 patients with MUCH, 69 (85.2%) were fully adherent and 12 (14.8%) were partially adherent (fewer medications detected than prescribed). Of the 77 patients with true controlled hypertension, 69 (89.6%) were fully adherent with prescribed antihypertensive medications and 8 (10.4%) were partially adherent. None of the patients in either group were fully nonadherent. There was no statistically significant difference in complete or partial adherence between the MUCH and true controlled groups (P=0.403). Measurement of urinary drug and drug metabolite levels demonstrates a similarly high level of antihypertensive medication adherence in both MUCH and truly controlled hypertensive patients. These findings indicate that MUCH is not attributable to antihypertensive medication nonadherence.

Increased double product on Monday morning during work. Hypertens Res 2017; 40:671-674. [PMID: 28905851 PMCID: PMC5506244 DOI: 10.1038/hr.2017.16] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2016] [Revised: 12/11/2016] [Accepted: 12/26/2016] [Indexed: 12/17/2022]
Abstract
It has been reported that cardiovascular events often occur on Monday morning, especially in the young working population. Because hypertension is a major cardiovascular risk, we examined whether blood pressure was elevated on Monday, especially in the morning during work. However, there were no weekly rhythms in blood pressure itself. Instead, we found significant interactions between the double product (systolic blood pressure × heart rate) and weekly (high on Monday) and circadian (high in the morning) rhythms. Further studies are required to determine whether Monday morning preference in cardiovascular events is caused by increased double product.
