Abstract Introduction Abnormal nocturnal blood pressure(BP) such as non-dipping or nocturnal hypertension(reverse-dipping) represents a potent marker for cardiovascular risks. Standard cuff-based ambulatory nocturnal BP measurement yields limited data points potentially resulting in imprecise results, especially compared to continuously recorded BP. We hypothesized nocturnal BP based on periodic measurement would be different from true average beat-to-beat based BP. Methods We prospectively enrolled patients undergoing clinically indicated in-lab polysomnography, both CPAP and non-CPAP studies, for sleep apnea evaluation. Nocturnal BP was continuously monitored beat-to-beat by a noninvasive Caretaker™ device, which uses the Pulse Decomposition Analysis(PDA) algorithm. We compared BP recorded at 30-minute intervals with average BP continuously recorded over 30 minutes, both recorded by Caretaker™. We also looked at the differences between recording spot and continuous BP from an awake or sleeping state and BP variability(SD) based on continuously recorded BP. Using first 30 min as a reference, we determined dipping status (dipping: 10-20% reduction, level: 0-10% reduction, riser: any increase) by the two methods. Results A total of 18 patients were recruited(male:11, mean age:52.2). Among a total of 261 periodic BP measurements, 60 (30.0%) were obtained while awake. Mean nocturnal SBP by periodic BP measurement was higher compared with beat-to-beat-derived average BP(135.6mmHg[24.2] vs. 131.5[20.3], p<0.0001). The difference between the two methods remained similar when continuous BP was derived from sleep vs. awake period(4.5mmHg[3.1] vs. 7.7[9.9], p=0.202). BP variability was more pronounced during awake compared with sleep period(6.7mmHg[8.1] versus 3.95[7.5], p=0.047). 8 patients were dippers by spot check measurement, but 11 were dippers by continuous BP. Conclusion Standard ambulatory periodic nocturnal BP recording may not yield true sleep BP patterns due to its spot-check nature and lack of sleep-awake information, which leads to inaccurate dipping measurements. Incorporation of beat-to-beat continuous BP measurement can provide more accurate and meaningful nocturnal BP information. Support N/A

Abstract Background Little is known about seasonal variation in nighttime blood pressure (BP) measured by a home device. In this cross-sectional study, we sought to assess seasonal variation in nighttime home BP using data from the nationwide, practice-based Japan Morning Surge-Home BP (J-HOP) Nocturnal BP study. Methods In this study, 2544 outpatients (mean age 63 years; hypertensives 92%) with cardiovascular risks underwent morning, evening and nighttime home BP measurements (measured at 2:00, 3:00, and 4:00 AM) using validated, automatic and oscillometric home BP devices. Results Our analysis showed that nighttime home systolic BP (SBP) was higher in summer than in other seasons (summer, 123.3±14.6 mmHg vs. spring, 120.7±14.8 mmHg; autumn, 121.1±14.8 mmHg; winter, 119.3±14.0 mmHg; all p<0.05). Moreover, we assessed seasonal variation in the prevalence of elevated nighttime home SBP (≥120 mmHg) in patients with non-elevated daytime home SBP (average of morning and evening home SBP <135 mmHg; n=1565), i.e. masked nocturnal hypertension, which was highest in summer (summer, 45.6% vs. spring, 27.2%; autumn, 28.8%; winter, 24.9%; all p<0.05). Even in intensively controlled morning home SBP (<125 mmHg), the prevalence of masked nocturnal hypertension was higher in summer (summer, 27.4% vs. spring, 14.2%; autumn, 8.9%; winter, 9.0%; all p<0.05). The urine albumin-creatinine ratio in patients with masked nocturnal hypertension tended to be higher than that in patients with non-elevated both daytime and nighttime SBP throughout each season. Conclusions The prevalence of masked nocturnal hypertension was higher in summer than other seasons and the difference proved to be clinically meaningful.

Abstract: Hypertension and anxiety are among the group of the most common chronic disease worldwide, and according to numerous studies they are oftentimes associated each other. Patients suffered from chronic illnesses, such as hypertension, may have negative emotion that increases the risk of mental disorders, most commonly anxiety disorder. This study was aimed to assess the difference of anxiety degree between uncontrolled and controlled hypertensive patients. This was an observational analytical study with a cross-sectional design. Subjects were divided into two groups: controlled and uncontrolled hypertensive patients. Measurement of blood pressure parameter was performed by using office blood pressure monitoring. Anxiety parameter was classified based on the scoring of the Generalized Anxiety Disorder Scale (GAD-7). Data were analyzed by using the Mann-Whitney test. Subjects consisted of 60 hypertensive patients (35 males and 25 females), aged 30-70 years (mean 56.48 years). There were 35 controlled hypertension patients and 22 uncontrolled hypertensive patients. The results showed that the difference in anxiety degree based on GAD-7 between controlled hypertensive and uncontrolled hypertensive groups obtained a p-value of 0.000. In conclusion, there was a significant difference in anxiety degree between uncontrolled and controlled hypertensive patients. Screening for anxiety among hypertensive patients is a simple and cost-effective tool that may improve outcomes.Keywords: anxiety, uncontrolled hypertension, controlled hypertension Abstrak: Hipertensi dan ansietas merupakan kelompok penyakit kronik yang paling umum di seluruh dunia.

Introduction: Masked hypertension has been associated with increased cardiovascular disease (CVD) risk in Europeans and Asians. Hypothesis: Determine the association of masked hypertension with CVD events and all-cause mortality in African Americans (AA). Methods: The Jackson Heart Study, an exclusively AA population-based, prospective cohort study, was restricted to participants with clinic systolic/diastolic blood pressure (SBP/DBP) < 140/90 mmHg and valid ambulatory blood pressure monitoring (ABPM) at the baseline exam in 2000-2004 (n=738). Masked daytime hypertension was defined as mean ambulatory daytime (10am-8pm) SBP ≥ 135 mmHg or DBP ≥ 85 mmHg. Masked nocturnal hypertension was defined as mean ambulatory nighttime (12am-6am) SBP ≥ 120 mmHg or DBP ≥ 70 mmHg. Using all ABPM measurements, masked 24-hour hypertension was defined as mean SBP ≥ 130 mmHg or DBP ≥ 80 mmHg. CVD events (nonfatal/fatal stroke, nonfatal myocardial infarction or fatal coronary heart disease) and all-cause mortality were identified and adjudicated through December 31, 2011. Results: Any masked hypertension (masked daytime, nocturnal or 24-hour hypertension) was present in 52.2% of participants; 28.2% had masked daytime hypertension, 48.2% had masked nocturnal hypertension and 31.7% had masked 24-hour hypertension. There were 51 CVD events and 44 deaths over a median follow up of 8.2 and 8.5 years, respectively. The CVD rate (95% CI) per 1,000 person years in participants with and without any masked hypertension were 13.5 (9.9-18.4) and 3.9 (2.2-7.1), respectively (Table). The multivariable adjusted hazard ratio (95% CI) between any masked hypertension and CVD was 2.49 (1.26-4.93). CVD rates for those with and without masked daytime, nocturnal and 24-hour hypertension, and the hazard ratios for CVD associated with masked daytime, nocturnal and 24-hour hypertension, were similar. Masked hypertension was not associated with all-cause mortality. Conclusion: Masked hypertension is common and associated with increased CVD risk in AAs.

Purpose:A case-control study to explore the diurnal variation of blood pressure (BP) in patients with central serous chorioretinopathy (CSCR).Methods:One-hundred patients (50 cases with central serous chorioretinopathy and 50 age- and sex-matched controls) participated in this study. Twenty-four-hour BP was recorded by auscultatory method using manual standard mercury sphygmomanometer by a single, trained observer. Hypertension was categorised according to the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC-VII) classification.Results:Mean systolic BP (SBP) and diastolic BP (DBP) in cases and controls were 123.4 mmHg (range 112.3–134.6), 81.72 mmHg (range 73.0–90.5); 118.33 mmHg (range 108.4–128.2); and 77.50 mmHg (range 71.4–83.6), respectively. The difference in SBP and DBP was statistically significant at p=0.02 for the former and p=0.006 for the latter. The mean difference in maximum and minimum SBP in cases was 18 (±15.81) mmHg versus 9.04 (±3.08) mmHg in controls (p=0.001). Mean difference for DBP in cases was 15.16 (±7.86) mmHg versus 9.16 (±3.68) mmHg in controls (0.001). On the JNC-VII classification scale for hypertension, 66 % of cases were found to be pre-hypertensive (60 %) or hypertensive (6 %). Comparative figures for controls were pre-hypertension (30 %) and hypertension (2 %). The mean SBP and DBP was consistently higher in patients with CSCR compared with controls over the entire 24-hour period. The difference in variation between maximum and minimum SBP and DBP was also found to be statistically significant between the groups.Conclusion:A significant correlation exists between higher values BP and central serous chorioretinopathy. Screening of CSCR patients for pre-hypertension may be useful in decreasing the risk of progression to established hypertension, with its associated risks.

Background Ambulatory blood pressure monitoring (ABPM) is important in evaluating average 24-hour blood pressure (BP) levels, circadian rhythm, sleeping BP and BP variability but many patients are reluctant to use standard ABPM devices. Methods We compared two validated ABPM devices, the BPro tonometric wrist monitor and the A&D TM-2430 oscillometric upper arm monitor, for agreement of recordings and acceptability in 37 hypertensive patients (aged 55±9 years). Results Successful BP measurements were less frequent with the wrist-type than the arm-type device during the sleeping (66.3% vs. 92.9%, P <0.01) and awake periods (56.2% vs. 86.5%, P <0.01). Comparable paired readings showed no significant difference in systolic BP but diastolic BP (DBP) values were higher with the wrist compared to the arm monitor (24-hour 89±13 vs. 85±14 mmHg, P <0.01) with similar differences awake and sleeping. Bland-Altman analysis showed some large discrepancies between individual arm and wrist monitor measurements. More patients found the wrist monitor more comfortable to use than the arm monitor. Conclusions Despite the difference in individual BP measurements and the systematic overestimation of DBP values with the BPro device, wrist monitors with good patient acceptability may be useful to facilitate ABPM in some patients to provide additional information about cardiovascular risk and response to antihypertensive therapies.

Abstract Funding Acknowledgements Aga Khan University Faculty of Health Sciences Research Committee (#80096) On Behalf PC BP (Post Clinic Blood Pressure) Study Group Background Nocturnal non-dipping increases cardiovascular morbidity and mortality in both hypertensive and normotensive subjects. Ambulatory blood pressure monitoring(ABPM) can identify nocturnal blood pressure(BP) dipping patterns but clinic BP cannot. We previously showed that 15-minute post-clinic BP correlates well with 24- hour ABPM. Purpose We aimed to determine if 15-minute post-clinic BP reading helped to identify patients with nocturnal non-dipping pattern. Methods A cross-sectional study involving 150 participants, as part of the Post Clinic-Ambulatory Blood Pressure(PC-ABP) study, was conducted in cardiology clinics. Participants aged ≥18 years, with hypertension or those referred for its assessment, were included. Pregnant females were excluded. Post-clinic BP was taken 15 minutes after the patient-physician encounter in the clinic using an automated, validated BP device by a research assistant. All the participants were then referred for 24-hour ABPM. Patterns of nocturnal dipping were studied amongst groups of controlled(&lt;140 mmHg) and uncontrolled(≥140mmHg) post-clinic systolic BP(SBP). Fischer exact test was used to determine the difference in dipping patterns amongst the two groups. Results The mean age of participants was 60.3 ± 11.9 years. Of 150 participants, 49% were male and of all, 76% were hypertensive. Mean nighttime SBP(±SD) was 121.9(±18) mmHg(p-value &lt;0.001). Mean nighttime DBP(±SD) was 68.7(± 8.7) mmHg(p &lt; 0.001). Patterns of nocturnal dipping amongst patients with mean post-clinic SBP &lt;140mmHg versus ≥140mmHg has been shown in Table 1. The difference in nocturnal dipping patterns between the two groups was statistically insignificant(p-value 0.071). Pearson correlation coefficient between post-clinic SBP and nighttime SBP for patients with loss of dip was higher (0.64; p &lt; 0.001) whereas it was 0.56(p-value &lt;0.001) for those with preserved dip.  Conclusion Uncontrolled post-clinic BP can help in identifying patients with nocturnal non-dipping. Larger studies can help determine the prognostic value of post-clinic BP amongst patients with nocturnal non-dipping. Nocturnal Dipping Amongst The Two Groups Controlled PC SBP &lt;140mmHg (n = 80) Uncontrolled PC SBP ≥140mmHg (n = 70) Preserved Nocturnal Dipping (10 to 20% nocturnal drop in SBP) 61.2% (n = 49) 47.1% (n = 33) Loss of Dip (&gt;0% to &lt;10% of nocturnal drop in SBP) 33.8% (n = 27) 48.6% (n = 34) Reversed Dip (≤0% drop in SBP) 5% (n = 4) 1.4%(n = 1) Excessive Dip (&gt;20% drop in SBP) 0 2.9% (n = 2) Table 1 shows the patterns of nocturnal dipping amongst patients with controlled (&lt;140mmHg) and uncontrolled (≥140mmHg) 15-minute post-clinic systolic blood pressure (PC SBP).

To conduct a comparative analysis of daily blood pressure profile in patients with recurrent and primary ischemic stroke. We were examined 124 patients, of which 94 patients with ischemic stroke in acute period, which came to the hospital in up to 2 days after the onset of the disease and were observed in the neurological department. The control group consisted of 30 patients with hypertensive encephalopathy. The conducted analysis of daily blood pressure monitoring in patients with recurrent and primary ischemic stroke indicates the importance of using this diagnostic method as a reliable difference in many indicators of arterial pressure is obtained. The difference averages of daily monitoring of blood pressure for all periods day informative confirms the difference in blood pressure in patients with primary and repeated ischemic stroke, as observed significant difference of values: the day indices of systolic, diastolic, blood pressure pulse heart rate parameters. The study allowed to increase the effectiveness of the diagnosis of recurrent ischemic stroke by studying the characteristics of central hemodynamics.
