Masked Hypertension and Exaggerated Blood Pressure Response to Exercise: A Review and Meta-Analysis. Diagnostics (Basel) 2023; 13:diagnostics13061005. [PMID: 36980313 PMCID: PMC10047162 DOI: 10.3390/diagnostics13061005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Revised: 03/02/2023] [Accepted: 03/04/2023] [Indexed: 03/09/2023] Open
Abstract
Aim: Whether exaggerated blood pressure response (EBPR) to exercise represents a marker of masked hypertension (MH) in individuals with no prior history of hypertension is still unclear. We investigated this issue through a review and a meta-analysis of studies providing data on this association in normotensive individuals undergone both to dynamic or static exercise and to 24 h blood pressure monitoring (ABPM). Design: A systematic search was performed using Pub-Med, OVID, EMBASE, and Cochrane library databases from inception up to 31 December 2022. Studies were identified by using the following search terms: “masked hypertension”, “out-of-office hypertension”, “exercise blood pressure”, “exaggerated blood pressure exercise”, “exercise hypertension”. Results: Nine studies including a total of 387 participants with MH and 406 true normotensive controls were considered. Systolic BP (SBP) and diastolic BP (DBP) at rest were significantly higher in MH individuals than in sustained normotensives: 126.4 ± 1.4/78.5 ± 1.8 versus 124.0 ± 1.4/76.3 ± 1.3 mmHg (SMD: 0.21 ± 0.08, CI: 0.06–0.37, p = 0.007 for SBP; 0.24 ± 0.07, CI: 0.08–0.39, p = 0.002 for DBP). The same was true for BP values at peak exercise: 190.0 ± 9.5/96.8 ± 3.7 versus 173.3 ± 11.0/88.5 ± 1.8 mmHg (SMD 1.02 ± 0.32, CI: 0.39–1.65, p = 0.002 for SBP and 0.97 ± 0.25, CI: 0.47–1.96, p < 0.0001 for DBP). The likelihood of having an EBPR was significantly greater in MH than in their normotensive counterparts (OR: 3.33, CI: 1.83–6.03, p < 0.0001). Conclusions: Our meta-analysis suggests that EBPR reflects an increased risk of MH and that BP measurement during physical exercise aimed to assess cardiovascular health may unmask the presence of MH. This underscores the importance of BP measured in the medical setting at rest and in dynamic conditions in order to identify individuals at high cardiovascular risk due to unrecognized hypertension.

Aerobic exercise improves central blood pressure and blood pressure variability among patients with resistant hypertension: results of the EnRicH trial. Hypertens Res 2023:10.1038/s41440-023-01229-7. [PMID: 36813985 DOI: 10.1038/s41440-023-01229-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 02/01/2023] [Accepted: 02/06/2023] [Indexed: 02/24/2023]
Abstract
Central blood pressure (BP) and BP variability are associated with cardiovascular disease risk. However, the influence of exercise on these hemodynamic parameters is unknown among patients with resistant hypertension. The EnRicH (The Exercise Training in the Treatment of Resistant Hypertension) was a prospective, single-blinded randomized clinical trial (NCT03090529). Sixty patients were randomized to a 12-week aerobic exercise program or usual care. The outcome measures include central BP, BP variability, heart rate variability, carotid-femoral pulse wave velocity, and circulating cardiovascular disease risk biomarkers including high-sensitivity C-reactive protein, angiotensin II, superoxide dismutase, interferon gamma, nitric oxide, and endothelial progenitor cells. Central systolic BP decreased by 12.22 mm Hg (95% CI, -1.88 to -22.57, P = 0.022) as did BP variability by 2.85 mm Hg (95% CI, -4.91 to -0.78, P = 0.008), in the exercise (n = 26) compared to the control group (n = 27). Interferon gamma -4.3 pg/mL (95%CI, -7.1 to -1.5, P = 0.003), angiotensin II -157.0 pg/mL (95%CI, -288.1 to -25.9, P = 0.020), and superoxide dismutase 0.4 pg/mL (95%CI, 0.1-0.6, P = 0.009) improved in the exercise compared to the control group. Carotid-femoral pulse wave velocity, heart rate variability, high-sensitivity C-reactive protein, nitric oxide, and endothelial progenitor cells were not different between groups (P > 0.05). In conclusion, a 12-week exercise training program improved central BP and BP variability, and cardiovascular disease risk biomarkers in patients with resistant hypertension. These markers are clinically relevant as they are associated with target organ damage and increased cardiovascular disease risk and mortality.

Blood pressure variability in children with obesity and sleep-disordered breathing following positive airway pressure treatment. Pediatr Res 2022; 92:810-815. [PMID: 34785780 DOI: 10.1038/s41390-021-01841-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 10/14/2021] [Accepted: 10/28/2021] [Indexed: 11/09/2022]
Abstract
Obese youth with sleep-disordered breathing are treated with positive airway pressure to improve sleep and cardiovascular status. While improvements in sleep parameters have been confirmed, a study by Katz et al. showed no major improvement in ambulatory blood pressure. The aim of this ancillary study was to analyze short-term blood pressure variability, following positive airway pressure treatment, as a more sensitive marker of cardiovascular health. We analyzed 24-h blood pressure variability data in 17 children, taken at baseline and after 12 months of treatment. These data were derived from an already published prospective, multicenter cohort study conducted in 27 youth (8-16 years) with obesity who were prescribed 1-year of positive airway pressure for moderate-severe sleep-disordered breathing. Significant decreases were found in 24 h systolic blood pressure (p = 0.040) and nighttime diastolic blood pressure (p = 0.041) average real variability, and diastolic blood pressure (p = 0.035) weighted standard deviation. Significant decreases were noted in nighttime diastolic blood pressure time rate variability (p = 0.007). Positive airway pressure treatment resulted in a significant decrease in blood pressure variability, suggesting a clinically significant improvement of sympathetic nerve activity in youth with obesity and sleep-disordered breathing. IMPACT: Cardiovascular variability, as measured by blood pressure variability, is improved in children following positive airway pressure treatment. Our novel findings of improved blood pressure time rate variability are the first described in the pediatric literature. Future studies aimed at analyzing target organ damage in this patient population will allow for a better understanding as to whether alterations in blood pressure variability translate to decreasing target organ damage in children, as seen in adults.

Left ventricular mass as a predictor of cardiovascular events in the era of hypertension management using home blood pressure measurement: the J-HOP study. Hypertens Res 2022; 45:1240-1248. [PMID: 35562418 DOI: 10.1038/s41440-022-00927-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 03/15/2022] [Accepted: 04/10/2022] [Indexed: 12/22/2022]
Abstract
Target organ damage (TOD) is associated with a risk of cardiovascular disease (CVD) independent of blood pressure (BP); however, this association has been observed based on the assessment of office BP. We studied 1641 patients (mean age 64.8 ± 11.7 years) with CVD risk factors who underwent home BP measurement over a 14-day period and evaluated TOD at baseline and then performed follow-up examination of the J-HOP (Japan Morning Surge-Home Blood Pressure) study results. During the median follow-up of 6.6 ± 3.5 years, 115 participants experienced a CVD event. After adjustment for CVD risk factors, including office systolic BP, the adjusted hazard ratios expressing the risk of CVD events were 1.30 (95% confidence interval, 1.15-1.52), 1.27 (1.04-1.56), and 1.25 (1.11-1.40) per one-SD increase in log-transformed urinary albumin creatinine ratio (UACR, 0.57 mg/gCre), brachial-ankle pulse wave velocity (baPWV, 342 cm/s) and left ventricular mass index (LVMI, 26.6 g/m2) assessed by echocardiography, respectively. Even after adding home systolic BP as a covariate, these associations remained except for the association with baPWV (all P < 0.05). The C-statistic for the base model including office and home systolic BP for the risk of CVD events was 0.783 (95% CI: 0.743, 0.824), which significantly increased to 0.795 (95% CI: 0.757, 0.834) after adding LVMI, and changed slightly but not significantly with the addition of UACR or baPWV. Adding UACR, baPWV, or both to the model including LVMI did not improve CVD event prediction. In the modern era of hypertension management using home BP measurement, TOD indicators, especially LVMI, provide superior CVD event prediction independent of and beyond home BP.

Saylik F, Sarıkaya R. Can Systemic Immune-Inflammation Index Detect the Presence of Exxaggerated Morning Blood Pressure Surge in Newly Diagnosed Treatment-Naive Hypertensive Patients? Clin Exp Hypertens 2021; 43:772-779. [PMID: 34338559 DOI: 10.1080/10641963.2021.1960366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/20/2022]
Abstract
Background: The exaggerated morning blood pressure surge (MS) is associated with target organ damage and cardiovascular events. Systemic immune-inflammation index (SII) has been detected as a useful marker in tumors and cardiovascular diseases. The role of inflammation in the pathogenesis of hypertension is a well-known issue. We aimed to investigate whether there is an association between SII and exaggerated MS in newly diagnosed treatment-naive hypertensive patients.Material and Methods: In total, 343 newly diagnosed in clinical and 24-h ambulatory blood pressure (BP) monitoring treatment-naive hypertensive patients were included in this study. Morning surge was defined as the difference between morning BP, which was the mean of BP during 2 h after wake-up, and the lowest BP, which was the mean of three lowest BP during nighttime. A cutoff value of 52.1 mmHg was used to discriminate the high- and low value MS groups. SII was calculated based on neutrophil, platelet, and lymphocyte counts.Results: Neutrophil, platelet, SII, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) were higher, whereas lymphocyte counts were lower in the high-value MS than the low-value MS. These indices were all independently associated with exaggerated MS and SII was superior to all other indices for detecting the presence of exaggerated MS. SII was moderately correlated with morning BP surge (r: 0.489, p < 0.0001).Conclusion: SII was higher in patients with exaggerated MS and was independently associated with exaggerated MS. Furthermore, SII might be a better indicator than platelet, neutrophil, lymphocyte, NLR, and PLR for the presence of exaggerated MS.

Abstract
The study by Triantafyllidi et al. supports the view that regression of subclinical cardiac damage requires an effective 24‐hour blood pressure (BP) control along with a reduction in BP variability and suggests that the assessment of BPV and its modifications during the course of therapy may be an useful approach in predicting the beneficial effects of treatment on cardiac structure. However, some aspects and limitations of this study require caution in drawing firm conclusions. So, further investigation is needed to determine if reduction of BPV is actually associated with a regression in cardiac and extracardiac organ damage to identify which which classes of antihypertensive drugs are most effective in reducing BPV, and to elucidate whether those treatments provide additional clinical benefit, independent of the conventional BP targets.

Abstract
Background: Ascending aortic aneurysms are one of the primary causes of mortality. However, not much is known about the etiologies of aortic aneurysm. Recently, in hypertensive (HT) patients, blood pressure variability (BPV) has been recommended as a remarkable risk factor for adverse cardiovascular outcomes. This study aimed to explore the association between short-term BPV and ascending aortic dilatation (AAD).Methods: In this study, a total of 53 HT patients with AAD (aortic size index [ASI] ≥21 mm/m2) and 126 HT patients with a normal ascending aortic diameter (ASI <21 mm/m2) were included. Baseline, echocardiographic, and 24-h ambulatory blood pressure (BP) monitoring results were compared between groups. Standard deviation (SD) and coefficient of variation (CV) of BP were used to determine short-term BPV.Results: Except for daytime SBP values, daytime, nighttime, and 24-h mean systolic (SBP) and diastolic (DBP) BP levels were similar between groups. Compared with the HT patients with normal AA, daytime SBP, daytime SD of SBP, 24-h SD of SBP, daytime CV of SBP, and 24-h CV of SBP were significantly higher in HT patients with AAD. Compared with the HT patients with normal AA, the frequency of nondipper pattern was higher and dipper pattern was lower in HT patients with AAD. In multivariate logistic regression analysis, the daytime CV of SBP, daytime SD of SBP, 24-h SD of SBP, daytime SBP, and left ventricular mass index were independently associated with AAD. In receiver operating characteristic curve analysis, the daytime CV of SBP levels of >12.95 had a sensitivity of 61% and a specificity of 59% (area under the curve, 0.659; 95% CI, 0.562-0.756; P= .01); moreover, daytime SD of SBP > 16.4 had sensitivity of 62% and specificity of 61% (AUC, 0.687; 95% CI, 0.591-0.782; P< .001).:Conclusion Increased short-term BPV is independently associated with AAD and may be recommended as a remarkable factor risk for AAD in HT patients.
