Home blood pressure monitoring (HBPM) overcomes many of the limitations of traditional office blood pressure (BP) measurement and is both cheaper and easier to perform than ambulatory BP monitoring. Monitors that use the oscillometric method are currently available that are accurate, reliable, easy to use, and relatively inexpensive. An increasing number of patients are using them regularly to check their BP at home, but although this has been endorsed by national and international guidelines, detailed recommendations for their use have been lacking. There is a rapidly growing literature showing that measurements taken by patients at home are often lower than readings taken in the office and closer to the average BP recorded by 24-hour ambulatory monitors, which is the BP that best predicts cardiovascular risk. Because of the larger numbers of readings that can be taken by HBPM than in the office and the elimination of the white-coat effect (the increase of BP during an office visit), home readings are more reproducible than office readings and show better correlations with measures of target organ damage. In addition, prospective studies that have used multiple home readings to express the true BP have found that home BP predicts risk better than office BP (Class IIa; Level of Evidence A). This call-to-action article makes the following recommendations: (1) It is recommended that HBPM should become a routine component of BP measurement in the majority of patients with known or suspected hypertension; (2) Patients should be advised to purchase oscillometric monitors that measure BP on the upper arm with an appropriate cuff size and that have been shown to be accurate according to standard international protocols. They should be shown how to use them by their healthcare providers; (3) Two to 3 readings should be taken while the subject is resting in the seated position, both in the morning and at night, over a period of 1 week. A total of >or=12 readings are recommended for making clinical decisions; (4) HBPM is indicated in patients with newly diagnosed or suspected hypertension, in whom it may distinguish between white-coat and sustained hypertension. If the results are equivocal, ambulatory BP monitoring may help to establish the diagnosis; (5) In patients with prehypertension, HBPM may be useful for detecting masked hypertension; (6) HBPM is recommended for evaluating the response to any type of antihypertensive treatment and may improve adherence; (7) The target HBPM goal for treatment is <135/85 mm Hg or <130/80 mm Hg in high-risk patients; (8) HBPM is useful in the elderly, in whom both BP variability and the white-coat effect are increased; (9) HBPM is of value in patients with diabetes, in whom tight BP control is of paramount importance; (10) Other populations in whom HBPM may be beneficial include pregnant women, children, and patients with kidney disease; and (11) HBPM has the potential to improve the quality of care while reducing costs and should be reimbursed

BACKGROUND: Electronic monitoring devices (EMDs) are regarded as the gold standard for assessing medication adherence in clinical research. However, little is known about the effect of patients' acceptance of EMDs on medication adherence in African Americans with hypertension who are followed in primary care practices OBJECTIVE: To assess patients' perceptions of EMDs, their acceptance of EMDs, and the relationship of these perceptions to medication adherence in African Americans with hypertension who are followed in community-based practices. METHODS: Patients were recruited from a larger randomized controlled trial assessing the effect of motivational interviewing on medication adherence and blood pressure in hypertensive African American patients followed in 2 New York City primary care practices. Medication adherence was assessed with a Medication Event Monitoring System (MEMS) during a 12-month monitoring period. At the 12-month follow-up, patients' perceptions of the MEMS were assessed with a 17-item questionnaire. ANOVA was used to compare patients' responses (agree, neither, disagree) with the MEMS adherence over the monitoring period. Tukey's post hoc tests were used to determine whether there were significant differences among the 3 groups. RESULTS: Participants were predominantly women, low-income, unemployed, had a high school education, and were a mean age of 53 years. Approximately two-thirds of the participants stated that the MEMS helped them remember to take their medications, 93% reported that the MEMS was easy to open, 85% did not find it stressful, and 75% liked the MEMS and used it everyday. One-third of patients preferred using a pillbox and 25% did not like traveling with the MEMS. Patients who stated that they used the MEMS every day, felt comfortable using it in front of others, and remembered to put refills in the MEMS had significantly better adherence over the study period than did those who disagreed (p </= 0.05). CONCLUSIONS: African American patients treated for hypertension in community-based practices held positive perceptions about a MEMS. Perceptions about the practicality of a MEMS may yield important information about actual medication-taking behavior

The tendency for selected cardiovascular disease (CVD) risk factors to occur in clusters has led to the description of metabolic syndrome (MetS). The relative impact of the individual risk factor on the overall relative risk (RR) for cardiovascular death from metabolic syndrome is not well established and may differ across the different racial/ethnic groups. Using data from the National Health and Nutrition Examination Survey (NHANES II) mortality follow-up (NH2MS), we determined the prevalence and RR of cardiovascular death for individual components in the overall population and across racial and ethnic groups. The prevalence of MetS components varied significantly across gender and racial/ethnic groupings. The RR for CVD also varies for the number and different components of MetS. The adjusted RR for cardiovascular death was highest with diabetes (3.23; 95% CI: 2.70-3.88), elevated blood pressure (2.28; 95% CI: 1.94-2.67) and high triglycerides (1.63; 95% CI: 1.34-2.00). Although the RR for cardiovascular death differs significantly for some of the different components, the overall findings were similar across racial/ethnic groups. The two components that confer the highest risks for death are more prevalent in African Americans. We concluded that the RR of cardiovascular death associated with the diagnosis of MetS varies depending on the number and components used to establish the diagnosis of MetS and the racial/ethnic characteristic of the participants

OBJECTIVE: To determine what health behaviors patients choose to change in response to medical advice when they are given the potential net-present value (reduction in biological age) of modifying a behavior. METHODS: Baseline data for multiple health-risk behaviors that were recommended for change among 660 coronary angioplasty patients at the New York-Presbyterian Hospital-Weill-Cornell Medical Center who were enrolled during 2000--02 in one of two arms of a behavioral intervention trial designed to compare different approaches to communicating health risk (net-present vs. future value) were analyzed using multivariate statistical methods. RESULTS: Although there was no difference between study arms, knowing the biological-age value of behaviors, stage of change, and the total number of behaviors recommended for change was associated with choosing several behaviors. Notably, stage of change was associated in both groups with strength training (intervention OR 2.82, 95% CI 1.85, 4.30; comparison OR 2.84, 95% CI 1.83, 4.43, p<.0001) and reducing weight (intervention OR 2.49, 95% CI 1.32, 4.67, p=.005; comparison OR 1.98, 95% CI 1.80, 3.31, p=.01). CONCLUSION: Patients with coronary disease are more likely to choose strength training and reducing weight regardless of knowing the biological-age reduction of any given behavior

OBJECTIVE: Cardiovascular prognosis in diabetic white-coat hypertension (WCH) has not yet been described. We designed this study to investigate the impact of WCH on cardiovascular events in patients with type 2 diabetes, compared with those having type 2 diabetes along with sustained hypertension (SH), and with nondiabetic hypertensive individuals. METHODS: We performed ambulatory blood pressure (BP) monitoring in 1207 consecutive hypertensive patients at baseline, and they were followed up for 49+/-22 months. The mean age was 70.7+/-9.8 years; 262 had type 2 diabetes; and 945 did not. They were classified as having SH with diabetes (n=210); diabetic WCH (n=52); SH alone (n=719); or WCH alone (n=226), using awake BP of 135/85 mmHg as the cutoff value. Cox regression models were used to calculate hazard ratios (HR) and 95% confidence intervals of the risk for cardiovascular events, after controlling for age, sex, body mass index, current smoking, serum creatinine, and clinical systolic BP. RESULTS: During the follow-up period, 97 cardiovascular events occurred. The incidence of cardiovascular events in the diabetic SH group was significantly higher than in the diabetic WCH, nondiabetic SH, and nondiabetic WCH (P<0.05; log-rank test) groups. In Cox regression analysis, the diabetic SH group had significantly higher risk of cardiovascular events compared with the diabetic WCH group (HR: 8.2; 95% confidence intervals: 1.09-61.8; P=0.04). Although nonsignificant, the HRs in the SH and WCH groups, relative to diabetic WCH, exceeded 3.0. CONCLUSIONS: The cardiovascular prognosis for diabetic WCH was better than that for diabetic SH during 4 years of follow-up
