Mountain Sickness

Millions of people worldwide live at high altitude, being chronically exposed to hypobaric hypoxia. Hypertension is a major cardiovascular risk factor but data on its prevalence and determinants in highlanders are limited, and systematic studies with ambulatory blood pressure monitoring are not available. Aim of this study was to assess the prevalence of clinic and ambulatory hypertension and the associated factors in a sample of Andean highlanders. Hypertension prevalence and phenotypes were assessed with office and ambulatory blood pressure measurement in a sample of adults living in Cerro de Pasco, Peru (altitude 4340 m). Basic clinical data, blood oxygen saturation, hematocrit, and Qinghai Chronic Mountain Sickness score were obtained. Participants were classified according to the presence of excessive erythrocytosis and chronic mountain sickness diagnosis. Data of 289 participants (143 women, 146 men, mean age 38.3 years) were analyzed. Office hypertension was present in 20 (7%) participants, while ambulatory hypertension was found in 58 (20%) participants. Masked hypertension was common (15%), and white coat hypertension was rare (2%). Among participants with ambulatory hypertension, the most prevalent phenotypes included isolated nocturnal hypertension, isolated diastolic hypertension, and systodiastolic hypertension. Ambulatory hypertension was associated with male gender, age, overweight/obesity, 24-hour heart rate, and excessive erythrocytosis. Prevalence of hypertension among Andean highlanders may be significantly underestimated when based on conventional blood pressure measurements, due to the high prevalence of masked hypertension. In highlanders, ambulatory hypertension may be independently associated with excessive erythrocytosis.

Non-clinic blood pressure measurements are very important in confirming diagnosis of hypertension and they give us an idea of associated cardiovascular risk more precisely than clinic BP measurements. It can detect masked hypertension and white coat hypertension & ABPM especially can monitor night-time BP diagnosing individuals with nocturnal hypertension.  Masked hypertension and nocturnal hypertension are strongly related with target organ damage along with enhanced morbidity and mortality due to cardiovascular causes. ABPM can also measure early morning rise of BP, mean 24 hour BP, diurnal variation as well as average real variability. Home BP monitoring by patients themselves leads to their greater involvement in maintaining BP records and in achieving treatment goals. The purpose of this review is to preferentially discuss role of non-clinic BP monitoring in making accurate diagnosis and deciding treatment of hypertension that might help a great deal in reducing morbidity and mortality associated with it.        Asian Journal of Medical Sciences Vol.10(1) 2019 13-18

Objectiveof our study was to assess the ambulatory blood pressure monitoring (ABPM) in young people with different office blood pressure (BP).Design and methods. We included 981 students of a medical university at the age of 20–29 years (536 men, 445 women). ABPM was performed using the device “Kardiotekhnika 4000” (Inkart, Russia), the data were processed using the program “KT Result2” (Inkart, Russia).Results. The optimal BP during office measurement was recorded in 220 patients (22,4 %, group 1), normal — in 488 (49,8 %, group 2), high normal — in 134 (13,6 %, group 3), hypertension (HTN) 139 (14,2 %, group 4). The proportion of males was significantly higher in groups 3 and 4 (96,6 % and 85,6 %) compared with groups 1 and 2 (47,7 % and 40,2 %, respectively, p < 0,001). The median systolic BP (SBP) was 123 (110; 126) mm Hg, diastolic BP (DBP) — 85 (84; 87) mm Hg. According to the ABPM, the parameters of SBP and DBP correlated with the corresponding office BP parameters. A strong direct correlation was found for both SBP (rs= 0,87) and DBP (rs= 0,85). Daytime variability of SBP was significantly higher in individuals with high normal BP and HTN (15,9 ± 2,6 and 17,2 ± 4,2 mm Hg) compared to groups 1 and 2 (9,2 ± 4,4 and 9,9 ± 3,0, respectively, p < 0,05). The majority of young people had normal BP decrease at night (dipper), non-dipper profile was also frequent. Over-dipper and night-peaker profiles were rarely recorded. In the groups 3 and 4, a larger number of non-dipper patients were observed compared with groups 1 and 2 (23,9 % and 34,6 %, compared with 10,0 % and 11,1 %, respectively, p < 0,001). The prevalence of white-coat hypertension (WCH) among the young people was 0,31 % (95 % CI 0,06–0,75 %), among subjects with office HTN 2,2 % (95 % CI 0,4–5,3 %). The prevalence of masked hypertension (MHTN) in the studied population was 1,4 % (95 % CI 0,8–2,3 %), among normotensive subjects — 1,7 % (95 % CI 0,9–2,6 %), among subjects with high normal BP — 10,4 % (95 % CI 5,8–16,2 %).Conclusions. ABPM in young hypertensive patients is characterized by higher variability of daytime SBP. The majority (56,1 %)of HTN subjects had normal BP decrease at night. The prevalence of WCH among young people is 0,31 % (95 % CI 0,06–0,75 %). The prevalence of MHTN among young people is 1,4 % (95 % CI 0,8–2,3 %).

INTRODUCTION Renal scarring is the most common cause of arterial hypertension in children. High blood pressure (BP) and microalbuminuria contribute to the progression of chronic renal disease. OBJECTIVE The aims of the study were: to assess BP in children with renal scarring by continuous ambulatory blood pressure measurement (ABPM) in comparison to the casual method (CBP), and to determine the correlation between ambulatory blood pressure (ABP) and/or casual blood pressure (CBP) values and proteinuria in children with renal scarring. METHOD This forward-looking study comprised thirty-five children (26 girls and 9 boys), aged between 3-13 years, 10.4?3.9, X+SD. Blood pressure was measured using the casual method (CBP) with a mercury manometer; BP was measured three times and the average was taken as a referent value. ABPM was performed using the oscillometric method with the Space Labs device, model 90207. RESULTS 45.71% of patients were classified as hypertensive by ABPM, while only 22.6% of CBP measurements were above the 95th percentile (p<0.01). "White coat hypertension" was present in 40% of the patients. Non-dipping BP alteration was detected in 37.14% of the patients. CONCLUSION Nocturnal systolic hypertension (systolic non-dipping alteration) is very frequent in children with renal scarring. Nocturnal diastolic blood pressure, detectable only via ABPM, is positively correlated with proteinuria and may be an initial sign of the progression of renal scarring. ABPM is more sensitive than CBP in the evaluation of BP in children with renal scarring.

Introduction: According to available guidelines, home blood pressure monitoring (HBPM) can be used to diagnose hypertension and monitor its treatment; however, its effectiveness has rarely been studied in developing countries, including Iran. Objectives: This study aimed to evaluate the diagnostic accuracy of HBPM, as compared with that of 24-hour ambulatory blood pressure monitoring (ABPM) and office blood pressure measurement (OBPM). Patients and Methods: This study was conducted on 28 patients suspected of having primary hypertension. The blood pressure of the patients was measured by four methods. Initially, blood pressure was measured by a non-physician using a digital sphygmomanometer in a clinic (OBPM-Digital). After about 1 hour, blood pressure was measured by a physician at the clinic using a mercury sphygmomanometer (OBPM-Mercury). In the third stage, the patient’s blood pressure was monitored for 24 hours by the ABPM method. In the fourth stage, each subject used a digital sphygmomanometer to measure HBPM for seven consecutive days. Results: The blood pressure values measured through the ABPM method were significantly lower than those measured by other methods (P<0.05). The prevalence of hypertension diagnosed by OBPM-Mercury, OBPM-Digital, HBPM, and ABPM method was 82%, 54%, 50%, and 21%, respectively. As compared with ABPM as the gold standard, the diagnostic accuracy of HBPM, OBPM-Digital, and OBPM-Mercury was 64%, 61%, and 32%, respectively. The frequency of white coat hypertension (WCH) diagnosed by HBPM and ABPM methods was 39% and 64%, respectively, and the frequency of masked hypertension (MH) diagnosed was 7% and 4%, respectively. The sensitivity, specificity, and diagnostic accuracy of HBPM, as compared with ABPM, in detecting MH were 100%, 96%, and 97%, respectively; in addition, as compared with WCH, they were 56%, 90%, and 68%, respectively. Conclusion: The findings of the present study showed that HBPM had higher diagnostic accuracy than OBPM in diagnosing hypertension. Also, HBPM was able to detect MH with a high level of diagnostic accuracy, and in more than two-thirds of cases, it was also able to detect WCH and diagnose patients with sustained hypertension.

Heart Study

Several ambulatory blood pressure monitoring (ABPM) phenotypes including masked hypertension are associated with an increased risk for cardiovascular disease (CVD). Diabetes is associated with CVD risk as well as a higher prevalence of hypertension. However, little is known about whether ABPM phenotypes differ between individuals with versus without diabetes. We evaluated the association between diabetes and ABPM phenotypes including clinic hypertension, awake hypertension, sustained hypertension, nocturnal hypertension, non-dipping pattern, white coat hypertension, and masked hypertension in the Jackson Heart Study (JHS). Baseline data collection included two clinic blood pressure measurements using standardized protocols. ABPM measurements were taken in the 24 hours following the baseline visit. Diabetes was defined as fasting glucose ≥126 mg/dL, hemoglobin A1c ≥6.5%, or use of diabetes medications. Of the 1,032 JHS participants with valid ABPM data (67.7% female, mean age 59.2 years), 253 (24.5%) had diabetes. The prevalence of clinic hypertension was similar for participants with and without diabetes (Table 1). After multivariable adjustment, diabetes was associated with an increased prevalence ratio of awake, sustained, and masked hypertension and a lower prevalence ratio of white coat hypertension compared with individuals without diabetes. In summary, there was an increased prevalence of adverse blood pressure phenotypes among individuals with versus those without diabetes that was not captured in the clinic setting alone. The role of ABPM for identifying high risk individuals with diabetes should be further investigated.
