Hypoperfusion Intensity Ratio as an Indirect Imaging Surrogate in Patients With Anterior Circulation Large-Vessel Occlusion and Association of Baseline Characteristics With Poor Collateral Status. J Am Heart Assoc 2024:e030897. [PMID: 39158547 DOI: 10.1161/jaha.123.030897] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Accepted: 11/15/2023] [Indexed: 08/20/2024]
Abstract
BACKGROUND Collateral status (CS) plays a crucial role in infarct growth rate, risk of postthrombectomy hemorrhage, and overall clinical outcomes in patients with acute ischemic stroke (AIS) secondary to anterior circulation large-vessel occlusions (LVOs). Hypoperfusion intensity ratio has been previously validated as an indirect noninvasive pretreatment imaging biomarker of CS. In addition to imaging, derangements in admission laboratory findings can also influence outcomes in patients with AIS-LVO. Therefore, our study aims to assess the relationship between admission laboratory findings, baseline characteristics, and CS, as assessed by hypoperfusion intensity ratio in patients with AIS-LVO. METHODS AND RESULTS In this retrospective study, consecutive patients presenting with AIS secondary to anterior circulation LVO who underwent pretreatment computed tomography perfusion were included. The computed tomography perfusion data processed by RAPID (Ischema View, Menlo Park, CA) generated the hypoperfusion intensity ratio. Binary logistic regression models were used to assess the relationship between patients' baseline characteristics, admission laboratory findings, and poor CS. A total of 221 consecutive patients with AIS-LVO between January 2017 and September 2022 were included in our study (mean±SD age, 67.0±15.8 years; 119 men [53.8%]). Multivariable logistic regression showed that patients with AIS caused by cardioembolic and cryptogenic causes (adjusted odds ratio [OR], 2.67; 95% CI, 1.20-5.97; P=0.016), those who presented with admission National Institutes of Health Stroke Scale score ≥12 (adjusted OR, 3.12; 95% CI, 1.61-6.04; P=0.001), and male patients (adjusted OR, 2.06; 95% CI, 1.13-3.77; P=0.018) were associated with poor CS. CONCLUSIONS Stroke caused by cardioembolic or cryptogenic causes, admission National Institutes of Health Stroke Scale score of ≥12, and male sex were associated with poor CS, as defined by hypoperfusion intensity ratio in the patients with AIS-LVO.

BMC Med Inform Decis Mak 2024; 24:197. [PMID: 39030567 PMCID: PMC11264587 DOI: 10.1186/s12911-024-02593-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Accepted: 06/27/2024] [Indexed: 07/21/2024] Open
Abstract
BACKGROUND The risk assessment for survival in heart failure (HF) remains one of the key focuses of research. This study aims to develop a simple and feasible nomogram model for survival in HF based on the Heart Failure-A Controlled Trial Investigating Outcomes of Exercise TraiNing (HF-ACTION) to support clinical decision-making. METHODS The HF patients were extracted from the HF-ACTION database and randomly divided into a training cohort and a validation cohort at a ratio of 7:3. Multivariate Cox regression was used to identify and integrate significant prognostic factors to form a nomogram, which was displayed in the form of a static nomogram. Bootstrap resampling (resampling = 1000) and cross-validation was used to internally validate the model. The prognostic performance of the model was measured by the concordance index (C-index), calibration curve, and the decision curve analysis. RESULTS There were 1394 patients with HF in the overall analysis. Seven prognostic factors, which included age, body mass index (BMI), sex, diastolic blood pressure (DBP), exercise duration, peak exercise oxygen consumption (peak VO2), and loop diuretic, were identified and applied to the nomogram construction based on the training cohort. The C-index of this model in the training cohort was 0.715 (95% confidence interval (CI): 0.700, 0.766) and 0.662 (95% CI: 0.646, 0.752) in the validation cohort. The area under the ROC curve (AUC) value of 365- and 730-day survival is (0.731, 0.734) and (0.640, 0.693) respectively in the training cohort and validation cohort. The calibration curve showed good consistency between nomogram-predicted survival and actual observed survival. The decision curve analysis (DCA) revealed net benefit is higher than the reference line in a narrow range of cutoff probabilities and the result of cross-validation indicates that the model performance is relatively robust. CONCLUSIONS This study created a nomogram prognostic model for survival in HF based on a large American population, which can provide additional decision information for the risk prediction of HF.

Comparisons of an automated oscillometric device with a hybrid manual auscultatory device for the Korea National Health and Nutrition Examination Survey. J Clin Hypertens (Greenwich) 2024; 26:532-542.

Abstract
This study evaluated an oscillometric device (OD), Microlife WatchBP Office AFIB, and a hybrid manual auscultatory device (AD), Greenlight 300TM, to determine a suitable blood pressure (BP) measurement device for the Korea National Health and Nutrition Examination Survey in a mercury-free context. Adhering to the 2018 Universal Standard's suggested consensus, the study involved 800 subjects (mean age 51.2 ± 17.5 years; 44.3% male), who underwent triplicate BP measurements following 5 min of rest in a randomized order (OD-first: 398 participants; AD-first: 402 participants). BP difference was calculated as OD value minus AD value, with results stratified by measurement sequence. The overall BP difference and tolerable error probability were -1.1 ± 6.5/-2.6 ± 4.9 mmHg and 89.2%/92.5% for systolic/diastolic BP (SBP/DBP), respectively. Lin's concordance correlation coefficient was 0.907/0.844 for SBP/DBP (OD-first/AD-first: 0.925/0.892 for SBP, 0.842/0.845 for DBP). The overall agreement for hypertension (BP ≥ 140 and/or 90 mmHg) was 0.71 (p < 0.0001), and the OD underestimated the overall hypertension prevalence by 5.1%. Analysis of the AD-first data revealed a lower level of agreement compared to the OD-first data; however, the observed blood pressure difference adhered to Criterion 1 of the 2018 Universal Standard. Microlife met the Criterion 1 of 2018 Universal Standard but underestimated the prevalence of hypertension. The BP discrepancy increased with higher BP levels, male sex, and smaller AC. With increasing age, the discrepancy decreased for SBP and increased for DBP.

Association of Blood Pressure With Brain Ages: A Cohort Study of Gray and White Matter Aging Discrepancy in Mid-to-Older Adults From UK Biobank. Hypertension 2024; 81:906-916. [PMID: 38465593 DOI: 10.1161/hypertensionaha.123.22176] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Accepted: 12/11/2023] [Indexed: 03/12/2024]
Abstract
BACKGROUND Gray matter (GM) and white matter (WM) impairments are both associated with raised blood pressure (BP), although whether elevated BP is differentially associated with the GM and WM aging process remains inadequately examined. METHODS We included 37 327 participants with diffusion-weighted imaging (DWI) and 39 630 participants with T1-weighted scans from UK Biobank. BP was classified into 4 categories: normal BP, high-normal BP, grade 1, and grade 2 hypertension. Brain age gaps (BAGs) for GM (BAGGM) and WM (BAGWM) were derived from diffusion-weighted imaging and T1 scans separately using 3-dimensional-convolutional neural network deep learning techniques. RESULTS There was an increase in both BAGGM and BAGWM with raised BP (P<0.05). BAGWM was significantly larger than BAGGM at high-normal BP (0.195 years older; P=0.006), grade 1 hypertension (0.174 years older; P=0.004), and grade 2 hypertension (0.510 years older; P<0.001), but not for normal BP. Mediation analysis revealed that the association between hypertension and cognitive decline was primarily mediated by WM impairment. Mendelian randomization analysis suggested a causal relationship between hypertension and WM aging acceleration (unstandardized B, 1.780; P=0.016) but not for GM (P>0.05). Sliding-window analysis indicated the association between hypertension and brain aging acceleration was moderated by chronological age, showing stronger correlations in midlife but weaker associations in the older age. CONCLUSIONS Compared with GM, WM was more vulnerable to raised BP. Our study provided compelling evidence that concerted efforts should be directed towards WM damage in individuals with hypertension in clinical practice.

Abstract
Hot spring bathing is practiced to help manage hypertension. We retrospectively investigated the effects of hot spring bathing on hypertension with the aim of identifying a novel approach to prevent and manage hypertension. The study cohort comprised 99 patients aged ≥65 years admitted to Kyushu University Beppu Hospital between 1 December 2021 and 30 November 2022 who could walk by themselves and who used hot springs for ≥3 days during their hospital stay. The changes in both systolic and diastolic blood pressure were significantly decreased in the night-time bathing group (n = 21) compared with the noontime (n = 26) and afternoon (n = 52) groups. Night-time hot spring bathing was significantly associated with reduced systolic blood pressure the next morning in older adults. Although prospective randomized controlled trials on night-time hot spring bathing as a hypertension treatment are warranted to investigate whether the practice can prevent hypertension among adults aged ≥65 years, we have initiated a single-center, phase II study on the relationship between sleep quality and quality of life in hypertensive patients after night-time hot spring bathing.

Abstract
BACKGROUND The impact of blood pressure on cardiovascular disease (CVD) and mortality outcomes in older people with diabetes mellitus (DM) is not well quantified. Using a systematic review and meta-analysis of observational cohort studies, we aimed to compare the associations of blood pressure levels with cardiovascular and mortality outcomes in older people aged ≥ 65 years with or without DM. METHODS Studies were identified from MEDLINE, Embase, Web of Science, and search of bibliographies to July 2022. Study-specific risk ratios (RRs) with 95% confidence intervals (CIs) were pooled. RESULTS Forty-five unique observational cohort studies (n = 2305,189 participants) assessing the associations of systolic blood pressure (SBP) and/or diastolic blood pressure (DBP) levels with adverse cardiovascular outcomes were included. In the general population, the pooled RRs (95% CIs) of SBP ≥ 140 vs < 140 mmHg and per 10 mmHg increase for composite CVD/MACE were 1.26 (0.96-1.64) and 1.15 (1.08-1.23), respectively. The respective estimates were 1.56 (1.04-2.34) and 1.10 (1.04-1.18) for patients with DM. SBP ≥ 130 vs < 130 mmHg was not associated with an increased risk of adverse cardiovascular outcomes in both populations. SBP < 120 vs ≥ 120 mmHg was associated with an increased risk of all cause-mortality in the general population (n = 10 studies). DBP ≥ 90 mmHg was associated with an increased risk of some adverse cardiovascular outcomes in both populations. Interaction analyses suggested similar risk of outcomes in both populations. CONCLUSIONS Observational evidence suggests SBP and DBP confer similar cardiovascular and mortality risk in older adults in the general population and those with DM. A blood pressure target range of > 130/80 to < 140/90 mmHg may be optimal for patients ≥ 65 years with DM, but specific targets may need to be individualised based on patients' unique circumstances. Furthermore, findings do not support stringent blood pressure control in this population group. Definitive RCTs are needed to support these observational findings.

Abstract
BACKGROUND Hypertensive patients show highly heterogeneous treatment effects (HTEs) and cardiovascular prognosis, and not all benefit from intensive blood pressure treatment.Methods and Results: We used the causal forest model to identify potential HTEs of patients in the Systolic Blood Pressure Intervention Trial (SPRINT). Cox regression was performed to assess hazard ratios (HRs) for cardiovascular disease (CVD) outcomes and to compare the effects of intensive treatment among groups. The model revealed 3 representative covariates and patients were partitioned into 4 subgroups: Group 1 (baseline body mass index [BMI] ≤28.32 kg/m2and estimated glomerular filtration rate [eGFR] ≤69.53 mL/min/1.73 m2); Group 2 (baseline BMI ≤28.32 kg/m2and eGFR >69.53 mL/min/1.73 m2); Group 3 (baseline BMI >28.32 kg/m2and 10-year CVD risk ≤15.8%); Group 4 (baseline BMI >28.32 kg/m2and 10-year CVD risk >15.8%). Intensive treatment was shown to be beneficial only in Group 2 (HR 0.54, 95% confidence interval [CI] 0.35-0.82; P=0.004) and Group 4 (HR 0.69, 95% CI 0.52-0.91; P=0.009). CONCLUSIONS Intensive treatment was effective for patients with high BMI and 10-year CVD risk, or low BMI and normal eGFR, but not for those with low BMI and eGFR, or high BMI and low 10-year CVD risk. Our study could facilitate the categorization of hypertensive patients, ensuring individualized therapy.

Abstract
Background The "obesity paradox" has been elucidated in patients with heart failure (HF). Current guidelines introduce a target diastolic blood pressure (DBP) < 80 mmHg but >70 mmHg in HF patients. Due to reduced coronary perfusion, low DBP has a deleterious impact on cardiovascular outcomes. This present study aimed to assess the relationship between BMI and adjudicated clinical outcomes in HFpEF patients according to the status of DBP. Methods We analyzed the data in 1749 HFpEF patients from the Americas of the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist) Trial. The population was stratified by DBP (<70 mmHg, and ≥70 mmHg) and BMI strata (normal weight, overweight, and obesity). Cox proportional hazards models and competing-risks regression analysis were performed. Results At baseline, the median BMI and DBP were 32.9 kg/m2 (interquartile range 28.0-38.5 kg/m2) and 70 mmHg (interquartile range 62-80 mmHg), respectively. In the multivariable analysis, obesity was associated with better survival rates in the total HFpEF population (all-cause death: HR = 0.439, 95% CI 0.256-0.750; and cardiovascular death: HR = 0.378, 95% CI 0.182-0.787). In patients with DBP<70 mmHg, obesity was not significantly associated with reduced risks for all-cause death (HR = 0.531, 95% CI: 0.263-1.704) and cardiovascular death (HR = 0.680, 95% CI: 0.254-1.819). However, multivariate analyses for cardiovascular death (HR = 0.339, 95% CI: 0.117-0.983) and all-cause death (HR = 0.389, 95% CI: 0.156-0.969) were significant in patients with DBP≥70 mmHg. Nevertheless, there were no interactions between DBP and BMI. Conclusions The obesity paradox was observed in patients with HFpEF, regardless of DBP strata (<70 mmHg, and ≥70 mmHg).

Abstract
BACKGROUND Although intensively studied in patients with cardiovascular diseases (CVDs), the prognostic value of diastolic blood pressure (DBP) has little been elucidated in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This study aimed to reveal the prognostic value of DBP in AECOPD patients. METHODS Inpatients with AECOPD were prospectively enrolled from 10 medical centers in China between September 2017 and July 2021. DBP was measured on admission. The primary outcome was all-cause in-hospital mortality; invasive mechanical ventilation and intensive care unit (ICU) admission were secondary outcomes. Least absolute shrinkage and selection operator (LASSO) and multivariable Cox regressions were used to identify independent prognostic factors and calculate the hazard ratio (HR) and 95% confidence interval (CI) for adverse outcomes. RESULTS Among 13,633 included patients with AECOPD, 197 (1.45%) died during their hospital stay. Multivariable Cox regression analysis showed that low DBP on admission (<70 mmHg) was associated with increased risk of in-hospital mortality (HR = 2.16, 95% CI: 1.53-3.05, Z = 4.37, P <0.01), invasive mechanical ventilation (HR = 1.65, 95% CI: 1.32-2.05, Z = 19.67, P <0.01), and ICU admission (HR = 1.45, 95% CI: 1.24-1.69, Z = 22.08, P <0.01) in the overall cohort. Similar findings were observed in subgroups with or without CVDs, except for invasive mechanical ventilation in the subgroup with CVDs. When DBP was further categorized in 5-mmHg increments from <50 mmHg to ≥100 mmHg, and 75 to <80 mmHg was taken as reference, HRs for in-hospital mortality increased almost linearly with decreased DBP in the overall cohort and subgroups of patients with CVDs; higher DBP was not associated with the risk of in-hospital mortality. CONCLUSION Low on-admission DBP, particularly <70 mmHg, was associated with an increased risk of adverse outcomes among inpatients with AECOPD, with or without CVDs, which may serve as a convenient predictor of poor prognosis in these patients.

[PMID: 37050747 PMCID: PMC10098792 DOI: 10.3390/s23073689] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 03/30/2023] [Accepted: 03/30/2023] [Indexed: 06/19/2023]
Abstract
Routine blood pressure measurement is important for the early detection of various diseases. Recently, cuffless blood pressure estimation methods that do not require cuff pressurization have attracted attention. In this study, we investigated the effect of the light source wavelength on the accuracy of blood pressure estimation using only two physiological indices that can be calculated with photoplethysmography alone, namely, heart rate and modified normalized pulse volume. Using a newly developed photoplethysmography sensor that can simultaneously measure photoplethysmograms at four wavelengths, we evaluated its estimation accuracy for systolic blood pressure, diastolic blood pressure, and mean arterial pressure against a standard cuff sphygmomanometer. Mental stress tasks were used to alter the blood pressure of 14 participants, and multiple linear regression analysis showed the best light sources to be near-infrared for systolic blood pressure and blue for both diastolic blood pressure and mean arterial pressure. The importance of the light source wavelength for the photoplethysmogram in cuffless blood pressure estimation was clarified.

Abstract
Although the effect of intensive systolic blood pressure lowering is widely recognized, treatment-related low diastolic blood pressure still worrisome. This was a prospective cohort study based on the National Health and Nutrition Examination Survey. Adults (≥20 years old) with guideline-recommended blood pressure were included and pregnant women were excluded. Survey-weighted logistic regression and cox models were used for analysis. A total of 25 858 participants were included in this study. After weighted, the overall mean age of the participants was 43.17 (16.03) years, including 53.7% women and 68.1% non-Hispanic white. Numerous factors were associated with low DBP (<60 mmHg), including advanced age, heart failure, myocardial infarction, and diabetes. The use of antihypertensive drugs was also associated with lower DBP (OR, 1.52; 95% CI, 1.26-1.83). DBP of less than 60 mmHg were associated with a higher risk of all-cause death (HR, 1.30; 95% CI, 1.12-1.51) and cardiovascular death (HR, 1.34; 95% CI, 1.00-1.79) compared to those with DBP between 70 and 80 mmHg. After regrouping, DBP <60 mmHg (no antihypertensive drugs) was associated with a higher risk of all-cause death (HR, 1.46; 95% CI, 1.21-1.75). DBP <60 mmHg after taking antihypertensive drugs was not associated with a higher risk of all-cause death (HR, 0.99; 95% CI, 0.73-1.36). Antihypertensive drug is an important factor contributing to DBP below 60 mmHg. But the pre-existing risk does not increase further with an additional reduction of DBP after antihypertensive drugs treatment.

Abstract
In elderly chronic kidney disease (CKD) patients, isolated systolic hypertension is common, the rate of renal function decline is slow, and there is a high possibility of physical damage due to side effects such as drug use-related orthostatic hypotension. Therefore, there are still many questions about whether lowering blood pressure in elderly patients will actually improve prognosis. Since many blood pressure-related clinical studies exclude advanced CKD and the elderly, it is particularly difficult to define target blood pressure in these populations. A randomized controlled trial is needed to establish optimal blood pressure targets and treatment strategies in elderly patients with CKD. This review seeks to summarize the guidelines available at this time.

Clinical impact of blood pressure on cardiovascular death in patients 80 years and older following acute myocardial infarction: a prospective cohort study. Hypertens Res 2022; 45:1882-1890. [PMID: 36123399 DOI: 10.1038/s41440-022-01030-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2022] [Revised: 08/17/2022] [Accepted: 08/23/2022] [Indexed: 12/15/2022]
Abstract
Numerous trials have shown that lowering blood pressure (BP) reduces cardiovascular risk and mortality, yet data about the impact of BP on cardiovascular death risk in patients aged ≥80 years with acute myocardial infarction (AMI) are sparse. This study explored the prognostic value of BP for cardiovascular death during the first 48 h after admission following AMI among patients aged ≥80 years. A total of 1005 patients ≥80 years with AMI were enrolled. Average BP parameters, including systolic, diastolic, and pulse BP, over the first 48 h after admission were calculated. The end point was cardiovascular death. Receiver operating curve (ROC) analysis was used to identify whether BP was relevant to cardiovascular death. The relationship between BP levels and cardiovascular death was evaluated by Cox regression models. ROC analysis showed that average diastolic blood pressure (aDBP), but not systolic and pulse BP, was relevant to cardiovascular death, and the optimal cutoff was 65 mmHg. During the 2.9-year follow-up, patients who died from a cardiovascular cause had lower aDBP levels than those who did not (p = 0.002). Patients with aDBP <65 mmHg had a 1.5-fold higher incidence of cardiovascular death than those with aDBP ≥65 mmHg (35.9% vs. 24.0%; p < 0.001). In multivariable regression analysis, low aDBP remained a strong and independent predictor of cardiovascular death (adjusted hazard ratio 1.907; 95% CI 1.303-2.792). aDBP was independently associated with cardiovascular death in patients aged ≥80 years with AMI, suggesting that aDBP may be a useful index to predict worse outcome in these patients.

Decreased Diastolic Blood Pressure and Average Grip Strength in Adults With Type 1 Diabetes Compared With Controls: An Analysis of Data From the Canadian Longitudinal Study on Aging.

Abstract
OBJECTIVES Our aim in this study was to determine whether aging individuals with type 1 diabetes (T1D) have differences in cardiovascular health, assessed by blood pressure, and skeletal muscle function, assessed by grip strength, compared with matched nondiabetic controls (CON). METHODS This investigation was a retrospective cohort analysis using baseline and 3-year follow-up data from the Canadian Longitudinal Study on Aging. Bivariate and multivariate regression analyses were used to examine the association between sociodemographic, health, behavioural and T1D-specific variables on blood pressure and grip strength in T1D and CON groups. Generalized estimating equations were used to model the average population changes in blood pressure and grip strength from baseline to follow up. RESULTS The sample included 126 individuals (63 T1D and 63 CON). Systolic blood pressure was not significantly different between groups at baseline or follow up (p>0.05). However, compared with CON, diastolic blood pressure was significantly lower at both time-points in the T1D group (p<0.001). Grip strength was consistently lower among persons with T1D (p=0.03). In the multivariate regression model, body mass index, age and sex were significantly associated with diastolic blood pressure and grip strength in both groups. In the T1D group, disease duration accounted for a large proportion of the variance in diastolic blood pressure and grip strength (17% and 9%, respectively). The rate of decline in diastolic blood pressure and grip strength did not differ between groups (p>0.05). CONCLUSIONS Diastolic blood pressure and grip strength appear to be consistently lower and differentially regulated in individuals with T1D vs CON. Aging individuals with T1D may be at risk of premature morbidity and mortality.

Abstract
BACKGROUND Recommended systolic blood pressure targets often do not consider the relationship of low diastolic blood pressure (DBP) levels with cardiovascular disease (CVD) and all-cause mortality risk, which is especially relevant for older people with concurrent comorbidities. We examined the relationship of DBP levels to CVD and all-cause mortality in older women in the Women's Health Initiative Long Life Study (WHI-LLS). METHODS The study sample included 7,875 women (mean age: 79 years) who underwent a blood pressure measurement at an in-person home visit conducted in 2012-2013. CVD and all-cause mortality were centrally adjudicated. Hazard ratios (HRs) were obtained from adjusted Cox proportional hazards models. RESULTS After 5 years follow-up, all-cause mortality occurred in 18.4% of women. Compared with a DBP of 80 mm Hg, the fully adjusted HR for mortality was 1.33 (95% confidence interval [CI]: 1.04-1.71) for a DBP of 50 mm Hg and 1.67 (95% CI: 1.29-2.16) for a DBP of 100 mm Hg. The HRs for CVD were 1.14 (95% CI: 0.78-1.67) for a DBP of 50 mm Hg and HR 1.50 (95% CI: 1.03-2.17) for a DBP of 100 mm Hg. The nadir DBP associated with lowest mortality risk was 72 mm Hg overall. CONCLUSIONS In older women, consideration should be given to the potential adverse effects of low and high DBP. Low DBP may serve as a risk marker. DBP target levels between 68 and 75 mm Hg may avoid higher mortality risk.

Abstract
Objectives This study aimed to examine the risk of cardiovascular disease (CVD) death according to blood pressure levels and systolic and/or diastolic hypertension. Methods From 20,636 cohort participants, 14,375 patients were enrolled after patients with prior hypertension on antihypertensive drugs were excluded. For the combination analysis, participants were divided into four groups (systolic/diastolic hypertension, systolic hypertension only, diastolic hypertension only, and non-hypertension). The risk of CV death was calculated using the hazard ratio (HR) and 95% confidence intervals (95% CI) in a Cox regression model. Results The risk of CVD death increased in systolic hypertension (HR = 1.59, 95% CI 1.26–2.00) and systolic/diastolic hypertension (HR = 1.84, 95% CI 1.51–2.25). The highest risks of hemorrhagic and ischemic stroke were observed in the diastolic hypertension (HR = 4.11, 95% CI 1.40–12.06) and systolic/diastolic hypertension groups (HR = 2.59, 95% CI 1.92–3.50), respectively. The risk of CVD death was drastically increased in those with SBP≥120 mmHg/DBP≥80 mmHg. The highest risk was observed in those with SBP of 130–131 mmHg and 134–137 mmHg. Conclusion The combined analysis of systolic and/or diastolic hypertension appears to be a good predictor of CVD death. The risk of CVD death in the prehypertensive group could be carefully monitored as well as in the hypertensive group, presumably due to less attention and the lack of antihypertensive treatment.

Abstract
Over time, a focus on blood pressure has transferred from diastolic pressure to systolic pressure. Formal analyses of differences in predictive value are scarce. Our goal of the study was whether office SBP adds prognostic information to office DBP and whether both 24-h ambulatory SBP and 24-h ambulatory DBP is specifically important. The authors examined 2097 participants from a population cohort recruited in Copenhagen, Denmark. Cause-specific Cox regression was performed to predict 10-year person-specific absolute risks of fatal and non-fatal cardiovascular (CV) events. Also, the time-dependent area under the receiver operator curve (AUC) was utilized to evaluate discriminative ability. The calibration plots of the models (Hosmer-May test) were calculated as well as the Brier score which combines (discrimination and calibration). Adding both 24-h ambulatory SBP and 24-h ambulatory diastolic blood pressure did not significantly increase AUC for CV mortality and CV events. Moreover, adding both office SBP and office DBP did not significantly improve AUC for both CV mortality and CV events. The difference in AUC (95% confidence interval; p-value) was .26% (-.2% to .73%; .27) for 10-year CV mortality and .69% (-.09% to 1.46%; .082) for 10-year risk of CV events. The difference in AUC was .12% (-.2% to .44%; .46) for 10-year CV mortality and .04% (-.35 to .42%; .85) for 10-year risk of CV events. Moreover, for both CV mortality and CV events, office SBP did not improve prognostic information to office DBP. In addition, the Brier scores of office BP in both CV mortality and CV events were .078 and .077, respectively. Furthermore, the Brier scores were .077 and .078 in CV mortality and CV events of 24-h ambulatory. For the average population as those participating in a population survey, the 10-year discriminative ability for long-term predictions of CV death and CV events is not improved by adding systolic to diastolic blood pressure. This finding is found for ambulatory as well as office blood pressure.

Revascularization procedures, including percutaneous coronary intervention (PCI), for coronary artery disease (CAD) are increasingly performed in Korea. However, studies on blood pressure control targets in these patients remain insufficient. To assess the relationship between baseline blood pressure and all-cause mortality in CAD patients who underwent PCI. A population-based retrospective cohort study based on the national claims database of the Korean National Health Insurance System, which represents the entire Korean population. A total 38,330 patients with a history of PCI for CAD between 2005 and 2008 were recruited and followed up for all-cause mortality until December 31, 2017. Baseline systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured, and they were classified into eight SBP and DBP groups each. The hazard ratios (HRs) for all-cause mortality were measured for each group. The pattern of SBP and DBP in this population followed a J-curve relationship for all-cause mortality, with the nadir point at 119 and 74 mmHg, respectively. In subjects aged > 60 years, high SBP (≥ 160 mmHg) and high DBP (≥ 90 mmHg) were significantly related to death. Moreover, in subjects aged > 60 years, low DBP (< 70 mmHg) was significantly related to mortality. There is a J-curve relationship between baseline blood pressure and all-cause mortality in patients who underwent PCI, and intensive lowering of blood pressure may be beneficial for these patients. However, the elderly population needs more attention as excessive BP lowering, particularly DBP, could instead increase the risk of death.

Abstract
INTRODUCTION Hypertension is common and has a significant effect on cardiovascular morbidity and death. However, despite the development of several guidelines to manage SBP, there is little research or guidance on the evaluation and management of DBP or isolated diastolic hypertension (IDH). METHOD To determine the association of DBP with all-cause and cardiovascular mortality, we used NHANES data from 1999 to 2014 and included adults aged at least 18 years. The relationship between DBP, IDH and all-cause, cardiovascular mortality was evaluated. RESULTS Of the 35 109 participants, all-cause death occurred in 10.6%, and cardiovascular death occurred in 2.1% over a median follow-up of 7.2 years. Multivariate Cox regression analysis revealed that the risk of all-cause mortality was significantly higher in the lowest (≤56.9 mmHg) DBP groups than in the reference group (DBP 74-76.9 mmHg). However, the risk of cardiovascular mortality was significantly higher in the lowest and highest (≥83 mmHg) DBP group than in the reference group. The risk of all-cause mortality was higher for most groups with SBP at least 140 mmHg than for the reference group with DBP 74-76.9 mmHg and SBP 100-139.9 mmHg. Both the 2018 ESC/NICE and the 2017 AHA/ACC-defined IDH was not significantly associated with all-cause mortality. CONCLUSION DBP and all-cause mortality had an inverse relationship, whereas DBP and cardiovascular mortality had a U-shaped relationship, with the DBP reference group having the lowest risk for all-cause and cardiovascular mortality. There was no significant relationship between IDH and death.

Abstract
The association between pulse pressure and long-term mortality was investigated among acute coronary syndrome (ACS) patients who received percutaneous coronary intervention (PCI). The study population included 5055 ACS patients in the Department of Cardiology of Beijing Friendship Hospital who were enrolled from January 2013 to July 2019. The median duration of follow-up was 24 months. Multivariate Cox regression was used to analyze the relationships between PP on inpatient admission and mortalities. Non-linear associations were studied by restricted cubic splines. Considering the heart function, the analyses were performed in the whole cohort and the LVEF > = 0.5 cohort separately. Subgroup analyses were performed according to the different diagnosis (the myocardial infarction subgroup and the unstable angina pectoris subgroup). When PP was used as categorical variable, the high PP group (≥61 mm Hg) significantly increased the risk of death compared with the intermediate PP group (50-60 mm Hg) in the both cohorts. When PP was used as continuous variable, a U-shape relationship were found between PP and mortalities in the whole cohort (p (for nonlinearity) = .005 and .003, respectively), with reference PP level of 55 mm Hg. However, this U-shape relationship disappeared in the LVEF > 0.5 cohort (p (for nonlinearity) = .111 and .117, respectively). The similar results were obtained in MI subgroup. From this study, the U-shape relationships between PP level and all-cause and cardiac mortalities were found in ACS patients who underwent PCI. The U-shape relationships disappeared in the LVEF > 0.5 cohort. The reference PP level was 55 mm Hg.

Abstract
OBJECTIVES To assess the association of systolic blood pressure (SBP) and diastolic blood pressure (DBP) with mortality among older adults in Singapore. METHODS Association of SBP and DBP measured in 2009 for 4443 older adults (69.5±7.4 years; 60-97 years) participating in a nationally representative study with mortality risk through end-December 2015 was assessed using Cox regression. RESULTS Higher mortality risk was observed at the lower and upper extremes of SBP and DBP. With SBP of 100-119 mmHg as the reference, multivariable mortality hazard ratios [HRs (95% confidence interval)] were SBP <100 mmHg: 2.41 (1.23-4.72); SBP 160-179 mmHg: 1.51 (1.02-2.22); and SBP ≥180 mmHg: 1.78 (1.12-2.81). With DBP of 70-79 mmHg as the reference, HRs were DBP <50 mmHg: 2.41 (1.28-4.54) and DBP ≥110 mmHg: 2.16 (1.09-4.31). DISCUSSION Management of high blood pressure among older adults will likely reduce their mortality risk. However, the association of excessively low SBP and DBP values with mortality risk needs further evaluation.

Abstract
BACKGROUND The association between post-operative diastolic blood pressure (DBP) and pulse pressure (PP) with outcomes following transcatheter aortic valve replacement (TAVR) remains unclear. We sought to assess the prevalence, predictors, and impact of post-operative DBP and PP on presence of post-procedural aortic insufficiency (AI) and mortality in adults undergoing TAVR. METHODS The study population included 194 patients who underwent TAVR from 2016 to 2017 at an academic tertiary medical center, of which 176 had invasive arterial pressures available postoperatively. Low DBP and widened PP were defined as ≤40 mmHg and ≥80 mmHg respectively on invasive arterial line on post-operative day 1. Clinical outcomes of interest included post-procedural AI and 1-year all-cause mortality. RESULTS Post-operative low DBP and widened PP were noted in 32.4% and 58.5% of the study population. No significant association between post-operative AI and low DBP (p = 0.82) or widened PP (p = 0.32) was noted. There was a trend toward higher rates of mortality in patients with low DBP (19.3% vs 9.2%, p = 0.06) but no difference in mortality in patients with widened PP (10.7% vs 15.1%, p = 0.39) or those with ≥1+ post-procedural AI (16.7% vs 10.7%, p = 0.32). In multivariable analysis, low DBP was associated with a trend toward higher rates of 1-year mortality [odds ratio (OR) 2.43, 95% confidence interval (CI) 0.97-6.11, p = 0.06]. When excluding patients with a post-operative invasive systolic blood pressure < 80 mmHg, low DBP was associated with significantly higher risk-adjusted mortality at 1 year [OR 2.75, 95% CI (1.07-7.07), p = 0.04]. CONCLUSIONS In this contemporary study of adults undergoing TAVR, low DBP and widened PP were widely prevalent post TAVR. Low DBP was associated with a trend toward higher rates of 1-year mortality but not with post-procedural AI.

Abstract
BACKGROUND Previous studies revealed that abnormal blood pressure (BP) plays an important role in the pathogenesis of Alzheimer's disease (AD). However, little is known about the ambulatory BP characteristics of AD in the mild or severe stage. OBJECTIVE We explored the ambulatory BP characteristics of AD in the mild or severe stage. METHODS In the present study, 106 AD patients (42.5%male, average age 81.6 years) were enrolled from three centers in China. Clinal BP measurements at the supine and standing positions, neurological evaluations, and the 24 h ambulatory BP monitoring were performed. RESULTS In the 106 AD patients, 49.2%, 36.8%, and 70%of patients had 24 h, daytime, and nighttime systolic hypertension, respectively, while 19.8%, 29.2%, and 5.7%had 24 h, daytime, and nighttime diastolic hypotension. The prevalence of the reduced and reverse dipping pattern was 34.0%and 48.1%for systolic BP and 32.1%and 45.3%for diastolic BP, respectively. The daytime diastolic BP was significantly correlated with cognitive performance. After adjustment for age, sex, and body mass index, only daytime diastolic BP was associated with remarkable cognitive deterioration (p≤0.008). Further, AD patients in the severe stage had significantly lower levels of the 24 h, daytime, and nighttime diastolic BP, compared with those in the mild stage. CONCLUSION In general, AD patients were featured with high nighttime systolic BP, low daytime diastolic BP, and abnormal circadian BP rhythm of reduced and reverse dipping. The diastolic BP, especially daytime diastolic BP, was adversely correlated with the cognitive deterioration in AD.

Abstract
Background Although cuff-sphygmomanometry is used worldwide in medical and healthcare fields, it is a fact that the use of an occlusive cuff to obtain blood pressure (BP) is troublesome and inconvenient. There have therefore been on-going efforts to devise methods that do not require the use of a cuff, almost all being based on the measurement of pulse wave velocity or pulse transit time, but so far few significant developments have been made, especially regarding measurement accuracy. We have previously reported a smartphone-based cuffless method using a linear multiple regression calibration model comprising of BP obtained with a cuff-sphygmomanometer as an objective variable and modified normalized pulse volume (mNPV: a measure of vasoconstrictive activity in a finger) and pulse rate (PR) as explanatory variables. This requires a number of subjects to construct a calibration model and thus is largely dependent on the accuracy due to the model. To address these drawbacks, we report here a new cuffless method to surpass considerably the results of our previous study as well as earlier works. Methods With this method we can estimate BP, with much higher accuracy, using mNPV and PR, both also obtained from a smartphone-derived photoplethysmogram. The subject firstly performs a cuff-based BP measurement in parallel with the acquisition of mNPV and PR from a smartphone. These parameters are set as initial values (BPc0, mNPV0 and PR0; initial calibration procedure). Then, the estimated BP (BPe) can be calculated from the relation: “BPe = (BPc0·PR·mNPV)/(PR0·mNPV0)”, which is derived from the so-called haemodynamic Ohm’s law. To validate this method, preliminary experiments using 13 volunteers were carried out to compare results from the new method with those from the cuff-sphygmomanometry, used as a reference. Results Altogether 299 paired data sets were analyzed: A good agreement was found between the cuff-based and the estimated BP values, with correlation coefficients of 0.968 for systolic BP (SBP), 0.934 for mean BP (MBP) and 0.844 for diastolic BP (DBP). Bland-Altman analyses for the BPe (SBPe, MBPe, DBPe) and the BPc (SBPc, MBPc, DBPc) values also supported these comparison results. Mean absolute differences between the BPe and the BPc values in total subjects were less than 5 mmHg. Fairly good tracking availability in terms of time series data of the BPc against the corresponding BPe values was also confirmed in each subject during the study periods (1–2 weeks for 12 subjects and about 4 months for one subject). Discussion The present study reported the successful development of the new cuffless BP estimation method, given as the status of a trial stage of investigation. This method could easily be used with various smartphones, smart watches, and finger-based devices, and it appears to have significant potential as a convenient substitute for conventional cuff-sphygmomanometers as well as for practical application to mobile healthcare.

Abstract
In-vivo assessment of aortic characteristic impedance (Z ao ) and total arterial compliance (C T ) has been hampered by the need for either invasive or inconvenient and expensive methods to access simultaneous recordings of aortic pressure and flow, wall thickness, and cross-sectional area. In contrast, regional pulse wave velocity (PWV) measurements are non-invasive and clinically available. In this study, we present a non-invasive method for estimating Z ao and C T using cuff pressure, carotid-femoral PWV (cfPWV), and carotid-radial PWV (crPWV). Regression analysis is employed for both Z ao and C T . The regressors are trained and tested using a pool of virtual subjects (n = 3,818) generated from a previously validated in-silico model. Predictions achieved an accuracy of 7.40%, r = 0.90, and 6.26%, r = 0.95, for Z ao , and C T , respectively. The proposed approach constitutes a step forward to non-invasive screening of elastic vascular properties in humans by exploiting easily obtained measurements. This study could introduce a valuable tool for assessing arterial stiffness reducing the cost and the complexity of the required measuring techniques. Further clinical studies are required to validate the method in-vivo.

Abstract
BACKGROUND Independent associations between cardiovascular risk factor exposures during midlife and later life development of heart failure (HF) with preserved ejection fraction (HFpEF) versus reduced EF (HFrEF) have not been previously studied. METHODS We pooled data from 4 US cohort studies (Atherosclerosis Risk in Communities, Cardiovascular Health, Health , Aging and Body Composition, and Multi-Ethnic Study of Atherosclerosis) and imputed annual risk factor trajectories for body mass index, systolic and diastolic blood pressure, low-density lipoprotein and high-density lipoprotein cholesterol, and glucose starting from age 40 years. Time-weighted average exposures to each risk factor during midlife and later life were calculated and analyzed for associations with the development of HFpEF or HFrEF. RESULTS A total of 23,861 participants were included (mean age at first in-person visit, 61.8 ±1 0.2 years; 56.6% female). During a median follow-up of 12 years, there were 3666 incident HF events, of which 51% had EF measured, including 934 with HFpEF and 739 with HFrEF. A high midlife systolic blood pressure and low midlife high-density lipoprotein cholesterol were associated with HFrEF, and a high midlife body mass index, systolic blood pressure, pulse pressure, and glucose were associated with HFpEF. After adjusting for later life exposures, only midlife pulse pressure remained independently associated with HFpEF. CONCLUSIONS Midlife exposure to cardiovascular risk factors are differentially associated with HFrEF and HFpEF later in life. Having a higher pulse pressure during midlife is associated with a greater risk for HFpEF but not HFrEF, independent of later life exposures.

[PMID: 33420294 PMCID: PMC7794393 DOI: 10.1038/s41598-020-80705-3] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2020] [Accepted: 12/22/2020] [Indexed: 11/21/2022] Open
Abstract
Choroidal microvasculature dropout (CMvD) implies compromised optic nerve head perfusion in glaucoma patients. However, there are conflicting findings whether office-hour systemic blood pressure (BP) is related to the presence of CMvD. The present study investigated which systemic BP parameters, derived from 24-h ambulatory BP monitoring (ABPM), are associated with CMvD as assessed by optical coherence tomography angiography (OCT-A) in normal-tension glaucoma (NTG). This study included 88 eyes of 88 NTG patients who underwent 24-h ABPM and OCT-A imaging. Various systemic BP parameters associated with the presence of CMvD were evaluated using logistic regression analyses. CMvD was detected in 38 NTG eyes (43.2%). NTG eyes with CMvD had nighttime diastolic BP (DBP) dip of greater magnitude and longer duration than eyes without CMvD. In multivariate logistic regression, worse VF mean deviation (MD) (odds ratio [OR] 0.786; P = 0.001), greater nighttime DBP dip “%” (OR 1.051; P = 0.034), and higher daytime peak IOP (OR 1.459; P = 0.013) were significantly associated with the presence of CMvD. Based on our findings that the eyes with CMvD are closely associated with having nighttime DBP dip, NTG patients with CMvD should be recommended to undergo 24-h ABPM.

Usefulness of Ankle-Brachial Index Calculated Using Diastolic Blood Pressure and Mean Arterial Pressure in Predicting Overall and Cardiovascular Mortality in Hemodialysis Patients. Int J Med Sci 2021; 18:65-72. [PMID: 33390774 PMCID: PMC7738967 DOI: 10.7150/ijms.50831] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Accepted: 10/13/2020] [Indexed: 12/02/2022] Open
Abstract
No study has investigated the predictive ability of ankle-brachial index (ABI) calculated using diastolic blood pressure (DBP) (ABIdbp) and mean arterial pressure (MAP) (ABImap) for overall and cardiovascular (CV) mortality in hemodialysis (HD) patients. Our study was aimed to investigate the issue. Two hundred and seven routine HD patients were enrolled. ABI values were measured by ABI-form device. During the follow-up period (122 months), 124 of the 207 patients (59.0%) died, and 59 deaths due to CV cause. Multivariate analysis showed that low ABIsbp, ABIdbp, and ABImap were all significantly associated with increased overall (p ≤ 0.015) and CV mortality (p ≤ 0.015) in whole study patients. A subgroup analysis after excluding 37 patients with ABIsbp < 0.9 or > 1.3 found ABIsbp and ABIsbp < 0.9 were not associated with overall and CV mortality. However, ABImap and ABIdbp < 0.87 were significantly associated with overall mortality (p ≤ 0.042). Furthermore, ABIdbp and ABIdbp < 0.87 were significantly associated with CV mortality (p ≤ 0.030). In conclusion, ABIsbp, ABIdbp, and ABImap were all useful in predicting overall and CV mortality in our HD patients. In the subgroup patients with normal ABIsbp, ABIsbp and ABIsbp < 0.9 were not useful to predict overall and CV mortality. Nevertheless, ABImap and ABIdbp < 0.87 could still predict overall mortality, and ABIdbp and ABIdbp < 0.87 could predict CV mortality. Hence, calculating ABI using DBP and MAP may provide benefit in survival prediction in HD patients, especially in the patients with normal ABIsbp.

Abstract
INTRODUCTION Hypertension is very common in haemodialysis (HD) patients, and is associated with increased morbidity and mortality rates. The goals of our research were to: 1. Measure blood pressure (BP) during HD sessions; 2. Study BP in between HD sessions with 44-h Ambulatory Blood Pressure Monitoring (ABPM); 3. Evaluate changes in treatment after the ABPM; 4. Perform bioimpedance spectroscopy (BIS) on all patients and, in those hyper-hydrated or hypertensive according to ABPM, assess for changes in BP after adjusting the dry weight; 5. Identify factors associated with average systolic and diastolic BP measured by ABPM. MATERIAL AND METHODS Prospective observational study, which included 100 patients from our dialysis unit. We measured BP before and after the HD sessions for two weeks and then, mid-week, we attached the ABPM device to the patients for 44 h. Before starting the following dialysis session, we performed BIS. A second ABPM was performed on hyper-hydrated patients and patients hypertensive according to ABPM to evaluate changes in BP values. RESULTS According to the ABPM, 65% of patients had daytime BP > 135/85 mmHg, 90% night-time BP > 120/70 mmHg and 76% average BP > 130/80 mmHg; 11% had a dipper pattern, 51% non-dipper and 38% riser. The average systolic and diastolic BP readings were 4.7 mmHg (3.8%) and 1.1 mmHg (1.64%) higher on the second day. The dose of antihypertensive medication had to be lowered in 6% of patients, 9% had to stop taking it, 28% needed increased doses and 17% had to add a new drug. The pre-HD diastolic BP best matched the ABPM. After performing the bioimpedance and adjusting dry weight, there was a statistically significant decrease in all BP values. The univariate analysis showed that the average systolic BP was higher in patients with a high-calcium dialysis bath, more antihypertensive drugs and higher doses of EPO. The multivariate analysis showed significant association for EPO and number of drugs (p < 0.01). The average diastolic BP was higher in younger patients and patients with lower Charlson index, lower body mass index and less diuresis, those on higher doses of EPO and non-diabetics. The linear regression study showed age (p < 0.005), body mass index (p < 0.03) and EPO (p < 0.03) as significant variables. CONCLUSIONS Our study shows: 1. The variability of hypertension criteria according to use of BP values from during the HD session or ABPM; 2. The variability of BP in the interdialysis period; 3. That the pre-dialysis diastolic BP best corresponds with the ABPM. 4. That the use of both BIS and ABPM improves the control of BP; 5. That the dose of EPO is the most important factor associated with hypertension in our patients.

Abstract
We investigated the optimal combinations of systolic blood pressure (SBP) and diastolic blood pressure (DBP) levels for lowest mortality in participants not taking hypertensive medication at the study baseline using nationwide representative databases. Survival rates and hazard ratios (HRs) were calculated using Kaplan-Meier curves and multivariable Cox regression analyses. The discriminatory ability for clinical outcomes was assessed by Harrell's C-index analysis. A survival spline curve was presented, and Classification and Regression Tree (CART) analysis was performed. SBP ≥ 140 group and DBP ≥ 90 group had the highest risk of mortality. Within SBP < 120, the HR (95% CIs) for all-cause mortality (ACM) was the lowest for DBP 70-79. Within SBP 120-139, the HR (95% CIs) for ACM was significantly lower for DBP 70-79. Within SBP ≥ 140, the HR (95% CIs) for ACM was significantly lower for DBP 80-89. Conversely, within SBP ≥ 140, DBP < 70 showed the highest risk for ACM. Similar relationships were observed when survival spline curves and CART analysis were used. The combination of SBP and DBP discriminated better than SBP or DBP alone for mortality. The effect of DBP on mortality varies according to the SBP range. It is more effective to evaluate the effect of SBP and DBP jointly for clinical outcomes.

Usefulness of ankle-brachial index calculated using diastolic blood pressure for prediction of mortality in patients with acute myocardial infarction. J Clin Hypertens (Greenwich) 2020; 22:2044-2050. [PMID: 33086427 DOI: 10.1111/jch.14032] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 08/17/2020] [Accepted: 08/24/2020] [Indexed: 11/29/2022]
Abstract
A low ankle-brachial index (ABI) calculated using systolic blood pressure (SBP) (ABIsbp) is associated with poor cardiovascular outcome in patients with acute myocardial infarction (AMI). ABI is always calculated using SBP clinically. However, there was no study investigating ABI calculated using mean artery pressure (MAP)(ABImap) and diastolic blood pressure (DBP)(ABIdbp) for mortality prediction in AMI patients. Therefore, our study was aimed to investigate the issue. 199 AMI patients were enrolled. Different ABIs were measured by an ABI-form device. The median follow-up to mortality was 64 months. There were 40 cardiovascular and 137 all-cause mortality. The best cutoff values of ABImbp and ABIdbp for mortality prediction were 0.91 and 0.78, respectively. After multivariate analysis, only ABIdbp and ABIdbp < 0.78 could predict cardiovascular mortality (P ≤ .047). However, all of six ABI parameters, including ABIsbp, ABImap, ABIdbp, ABIsbp < 0.90, ABImap < 0.91, and ABIdbp < 0.78, could predict all-cause mortality (P ≤ .048). In a direct comparison of six ABI models for prediction of all-cause mortality, basic model + ABIdbp <0.78 had the highest predictive value (P ≤ .025). In conclusion, only ABIdbp and ABIdbp < 0.78 could predict cardiovascular and all-cause mortality after multivariate analysis in our study. Furthermore, when adding into a basic model, ABIdbp < 0.78 had the highest additively predictive value for all-cause mortality in the six ABI parameters. Hence, calculation of ABI using DBP except SBP might provide an extra benefit in prediction of cardiovascular and all-cause mortality in AMI patients.

Roma Ethnicity and Sex-Specific Associations of Serum Uric Acid with Cardiometabolic and Hepatorenal Health Factors in Eastern Slovakian Population: The HepaMeta Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E7673.

Abstract
Background: Health characteristics associated with uric acid (UA) in the Roma minority remain less well known. The study sought to determine the ethnicity- and sex-specific associations of serum UA with health factors in Eastern Slovakian Roma and non-Roma populations. Methods: Data from the comparative cross-sectional HepaMeta study conducted in Slovakia in 2011 were used. The study enrolled 452 Roma subjects (35.2% men) and 403 non-Roma individuals (45.9% men) aged 18-55 years. Results: All study parameters differed between the sexes in both the Roma and non-Roma participants (p < 0.05). UA was related to sex with odds ratio for female sex 0.873, 95% CI 0.853-0.893 (p < 0.0001) per 10-unit increase of UA. Average level of UA ± standard deviation was lower in Roma than in non-Roma (226.54 ± 79.8 vs. 259.11 ± 84.53 umol/L; p < 0.0001). The Roma population presented with greater levels of high-sensitivity C-reactive protein (hsCRP) (3.07 ± 4 mg/L vs. 1.98 ± 2.83 mg/L; p < 0.0001) and ferritin in Roma males (403.78 ± 391.84 vs. 302.67 ± 236.26 mg/L; p < 0.0001). Conclusions: Serum UA is sex- and ethnicity specific. Elevated levels of hsCRP and ferritin particularly in Roma males can reflect low-grade systemic inflammation and thus serve as a marker of an increased cardiovascular risk.

Abstract
INTRODUCTION Hypertension is a major and modifiable risk factor for cardiovascular disease. Its prevalence is rising as the result of population aging. Isolated systolic hypertension mostly occurs in older patients accounting for up to 80% of cases. AREAS COVERED The authors systematically review published studies to appraise the scientific and clinical evidence supporting the role of blood pressure control in elderly patients with isolated systolic hypertension, and to assess the influence of different drug treatment regimens on outcomes. EXPERT OPINION Antihypertensive treatment of isolated systolic hypertension significantly reduces the risk of morbidity and mortality in elderly patients. Thiazide diuretics and dihydropyridine calcium-channel blockers are the primary compounds used in randomized clinical trials. These drugs can be considered as first-line agents for the management of isolated systolic hypertension. Free or fixed combination therapy with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers and calcium-channel blockers or thiazide-like diuretics should also be considered, particularly when compelling indications such as coronary artery disease, chronic kidney disease, diabetes, and congestive heart failure coexist. There is also hot scientific debate on the optimal blood pressure target to be achieved in elderly patients with isolated systolic hypertension, but current recommendations are scarcely supported by evidence.

Abstract
AIMS Type 2 diabetes mellitus (T2DM) is now very prevalent in China. Due to the lower rate of controlled diabetes in China compared to that in developed countries, there is a higher incidence of serious cardiovascular complications, especially acute coronary syndrome (ACS). The aim of this study was to establish a potent risk predictive model in the economically disadvantaged northwest region of China, which could predict the probability of new-onset ACS in patients with T2DM. METHODS Of 456 patients with T2DM admitted to the First Affiliated Hospital of Xi'an Jiaotong University from January 2018 to January 2019 and included in this study, 270 had no ACS, while 186 had newly diagnosed ACS. Overall, 32 demographic characteristics and serum biomarkers of the study patients were analysed. The least absolute shrinkage and selection operator regression was used to select variables, while the multivariate logistic regression was used to establish the predictive model that was presented using a nomogram. The area under the receiver operating characteristics curve (AUC) was used to evaluate the discriminatory capacity of the model. A calibration plot and Hosmer-Lemeshow test were used for the calibration of the predictive model, while the decision curve analysis (DCA) was used to evaluate its clinical validity. RESULTS After random sampling, 319 and 137 T2DM patients were included in the training and validation sets, respectively. The predictive model included age, body mass index, diabetes duration, systolic blood pressure (SBP), diastolic blood pressure (DBP), low-density lipoprotein cholesterol, serum uric acid, lipoprotein(a), hypertension history and alcohol drinking status as predictors. The AUC of the predictive model and that of the internal validation set was 0.830 [95% confidence interval (CI) 0.786-0.874] and 0.827 (95% CI 0.756-0.899), respectively. The predictive model showed very good fitting degree, and DCA demonstrated a clinically effective predictive model. CONCLUSIONS A potent risk predictive model was established, which is of great value for the secondary prevention of diabetes. Weight loss, lowering of SBP and blood uric acid levels and appropriate control for DBP may significantly reduce the risk of new-onset ACS in T2DM patients in Northwest China.

Comparison of different ankle-brachial indices in the prediction of overall and cardiovascular mortality. Atherosclerosis 2020; 304:57-63. [PMID: 32334850 DOI: 10.1016/j.atherosclerosis.2020.04.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2019] [Revised: 02/11/2020] [Accepted: 04/02/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND AND AIMS Low ankle-brachial index (ABI) calculated using systolic blood pressure (SBP) is associated with poor prognosis. However, there is no study assessing ABI calculated using mean artery pressure (MAP) and diastolic blood pressure (DBP) in predicting mortality. METHODS Two cohort populations were enrolled. The first population comprised 379 patients (106 patients with angiography-proved peripheral artery disease (PAD) and 273 relative normal patients) to evaluate the best cutoff values of ABImbp and ABIdbp for prediction of PAD. The second population included 941 patients undergoing echocardiographic examinations to assess the ability of different ABIs in predicting mortality. ABIs were measured using an ABI-form device. RESULTS The best cutoff values of ABImbp and ABIdbp for prediction of PAD were 0.92 and 0.88. In our second population, median follow-up to mortality was 93 months. There were 87 cardiovascular and 228 overall deaths. Multivariable analysis showed ABIsbp, ABImap, ABIdbp, ABIsbp <0.9, and ABImap <0.92 could predict overall and cardiovascular mortality (all p < 0.001). ABIdbp <0.88 could only predict CV mortality (p = 0.033). In a direct comparison of 6 multivariable models, the basic model consisting of significant variables in the univariable analysis plus ABImap <0.92 had the highest predictive value for overall and cardiovascular mortality (all p < 0.001). CONCLUSIONS In a direct comparison of 6 multivariable models, the basic model + ABImap < 0.92 was the best model in predicting overall and cardiovascular mortality. Hence, calculation of ABI using MAP except SBP might provide extra benefit in survival prediction.

Abstract
BackgroundWe sought to determine whether intensive systolic BP (SBP) lowering was harmful in Systolic Blood Pressure Intervention Trial (SPRINT) participants with CKD (eGFR<60 ml/min per 1.73 m2) and lower baseline diastolic BP (DBP).MethodsWe related baseline DBP with the SPRINT primary composite end point (myocardial infarction, acute coronary syndrome, stroke, acute decompensated heart failure, or cardiovascular death) and all-cause death. We examined the effect of intensive SBP lowering on these outcomes across the range of baseline DBPs using Cox regression with treatment by baseline DBP interaction terms.ResultsAmong 2646 SPRINT participants with CKD, lower baseline DBP was associated with a higher adjusted hazard of the primary composite end point and all-cause death. For example, participants with baseline DBP of 61 mm Hg (mean baseline DBP in the lowest tertile) experienced a 37% (95% CI, 7% to 75%) higher hazard of the primary outcome relative to participants with baseline DBP of 75 mm Hg (mean baseline DBP for overall). The benefit of intensive SBP lowering was consistent across a range of baseline DBPs on rates of the primary composite end point (linear interaction P value =0.56) and all-cause death (linear interaction P value =0.20).ConclusionsAmong SPRINT participants with baseline CKD, lower DBP was associated with higher rates of the primary composite end point and all-cause death. However, DBP did not seem to modify the benefit of intensive SBP lowering on the primary composite end point or all-cause death. Our results suggest that lower DBP should not necessarily impede more intensive SBP lowering in patients with mild to moderate CKD.

Abstract
Cardiovascular aging is a complex process of adaptive structural and functional changes over time. With advancing age, the arterial tree thickens and decreases in compliance, resulting in increased pulse wave velocity, systolic blood pressure, and left ventricular afterload. In response to these arterial changes, the myocardium remodels to maintain systolic function and diastolic filling. These adaptive mechanisms are not necessarily pathologic but increase the susceptibility for myocardial ischemia and heart failure in the presence of common age-associated comorbidities. This article reviews the pathophysiology of cardiovascular aging and discusses therapeutic interventions that may ameliorate these processes.

Abstract
Elderly long-term care facility residents typically have musculoskeletal conditions that may lead to long-term disability and increased mortality. Our main objective was to explore the relationship between body mass index (BMI), albumin levels, and mortality in elderly individuals with limited performance status. Among 182 participants (mean age, 78.8 years; 57% women), 11%, 64%, and 25% had serum albumin levels of <2.8, 2.8-3.5, and >3.5 g/dL, respectively. After multivariate adjustments, diastolic blood pressure >90 mmHg was associated with all-cause mortality [hazard ratio (HR) = 2.08, 95% confidence interval (CI) = 1.13-3.82; P = 0.018]. In addition, BMI <18.5 kg/m2 and albumin level <2.8 g/dL associated with higher mortality than BMI = 18.5-24 kg/m2 and albumin level > 3.5 g/dL (HR = 1.80, 95% CI = 1.11-2.94 and HR = 2.54, 95% CI 1.22-5.30, respectively; P = 0.018 and 0.013, respectively). Highest mortality was noted in participants with albumin levels <2.8 g/dL and BMIs <18.5 kg/m2 (HR = 6.12, 95% CI = 1.85-20.21, P = 0.003). Combined hypoalbuminemia (albumin level < 2.8 g/dL) and low BMI (<18.5 kg/m2) may be a useful prognostic indicator of high mortality risk in elderly individuals with limited performance status.

Abstract
Four-limb blood pressure measurement could improve mortality prediction in the elderly. However, there was no study to evaluate whether such measurement was still useful in predicting overall and cardiovascular (CV) mortality in acute myocardial infarction (AMI). Two hundred AMI patients admitted to cardiac care unit were enrolled. The 4-limb blood pressures, inter-limb blood pressure differences, and ankle brachial index (ABI) were measured using an ABI-form device. The median follow-up to mortality was 64 months (25th-75th percentile: 5-174 months). There were 40 and 138 patients documented as CV and overall mortality, respectively. After multivariable adjustment, the ankle diastolic blood pressure (DBP) on the lower side, ABI value, ABI < 0.9, interarm DBP difference, interankle systolic blood pressure (SBP) and DBP differences, interankle SBP difference ≥ 15 mmHg, and interankle DBP difference ≥ 10 mmHg could predict overall mortality (P ≤ 0.025). The ankle DBP on the lower side, interankle DBP difference, and interankle DBP difference ≥ 10 mmHg could predict CV mortality (P ≤ 0.031). In addition, in the Nested Cox model, the model including the ankle DBP on the lower side and the model including interankle DBP difference had the best value for overall and CV mortality prediction, respectively (P ≤ 0.031). In AMI patients, 4-limb blood pressure measurement could generate several useful parameters in predicting overall and CV mortality. Furthermore, ankle DBP on the lower side and interankle DBP difference were the most powerful parameters in prediction of overall and CV mortality, respectively.

Abstract
BACKGROUND Fluid therapy has a pivotal role in the management of acutely ill patients. However, whether or not a patient can tolerate additional intravascular volume is controversial and optimal strategy is unknown. Carotid femoral pulse wave velocity (cfPWV) evaluates arterial stiffness. OBJECTIVE To determine whether cfPWV can predict the ability of patients to tolerate clinically indicated acute fluid expansion. METHODS 50 consecutive patients requiring intravascular volume expansion were prospectively recruited in intensive care units. All subjects underwent transthoracic echocardiography, pulmonary ultrasound assessment, and a cfPWV study (S. Giovanni Bosco Hospital in Turin, Italy, between 2015 and 2016) at baseline and after 24 hours. Acute outcomes were registered at 24 hours ("soft" end points) and 30 days ('hard' end points: death, acute myocardial infarction, stroke, occurrence of atrial fibrillation, need for dialysis) after initial fluid therapy. Multivariate logistic regression was used to assess association of the initial cfPWV with outcomes. RESULTS cfPWV was significantly higher (10.6±3.6 vs 7.4±2.2 m/s, P<0.0001) in subjects who met the prespecified combined endpoints (hard or soft) than in those who did not. After adjustment for confounding factors, initial cfPWV was significantly and independently associated with the occurrence of hard events (OR=2.8 (95% CI 1.36 to 5.97), P=0.005; area under the receiver operating characteristic curve 84%). cfPWV of <9 m/s had a negative predictive value of 93%, excluding hard events associated with fluid expansion. CONCLUSION cfPWV appears to reflect the ability of the patient to tolerate an intravascular fluid expansion when clinically indicated. Increased cfPWV could help to identify subjects at greater risk of developing signs and symptoms of fluid overload.

Abstract
High protein diets may improve the maintenance of skeletal muscle mass in the elderly, although it remains less clear what broader impact such diets have on whole body metabolic regulation in the elderly. Non-targeted polar metabolomics analysis using HILIC HPLC-MS was used to profile the circulating plasma metabolome of elderly men (n = 31; 74.7 ± 4.0 years) who were randomized to consume for 10 weeks a diet designed to achieve either protein (RDA; 0.8·g−1·kg−1) or that doubled this recommend intake (2RDA; 1.6.g.kg−1). A limited number of plasma metabolites (n = 24) were significantly differentially regulated by the diet. These included markers of protein anabolism, which increased by the 2RDA diet, including; urea, creatine, and glutarylcarnitine. Whilst in response to the RDA diet; glutamine, glutamic acid, and proline were increased, relative to the 2RDA diet (p < 0.05). Metaboanalyst identified six major metabolic pathways to be influenced by the quantity of protein intake, most notably the arginine and proline pathways. Doubling of the recommended protein intake in older males over 10 weeks exerted only a limited impact on circulating metabolites, as determined by LC-MS. This metabolomic response was almost entirely due to increased circulating abundances of metabolites potentially indicative of altered protein anabolism, without evidence of impact on pathways for metabolic health. Trial Registration: This trial was registered on 3rd March 2016 at the Australia New Zealand Clinical Trial Registry (www.anzctr.org.au) at ACTRN 12616000310460.

Going Beyond the Guidelines in Individualising the Use of Antihypertensive Drugs in Older Patients. Drugs Aging 2019; 36:675-685. [PMID: 31175614 DOI: 10.1007/s40266-019-00683-8] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/05/2023]
Abstract
Hypertension is commonly diagnosed in older patients, with increasing cardiovascular (CV) risk as systolic blood pressure (BP) increases. Maximising CV risk reduction must be reconciled with minimising the risk of treatment-related harms and burden, especially among frail, multi-morbid and older old patients who have been excluded from most randomised trials. Contemporary clinical guidelines, based on such trials, differ in their recommendations as to threshold levels warranting treatment with antihypertensive drugs (AHDs) and target levels that should be achieved. In optimising AHD prescribing in older patients, we propose the following decision framework: decide therapeutic goals in accordance with patient characteristics and preferences; estimate absolute CV risk; measure and profile BP accurately in ways that account for lability in BP levels and minimise error in BP measurement; determine threshold and target BP levels likely to confer net benefit, taking into account age, co-morbidities, frailty and cognitive function; and consider situations that warrant AHD deprescribing on the basis of potential current or future harm. In applying this framework to older persons, and based on a review of relevant randomised trials and observational studies, individuals most likely to benefit from treating systolic BP to no less than 130 mmHg are those of any age who are fit and have high baseline systolic BP (≥ 160 mmHg); high CV risk, i.e. established CV disease or risk of CV events exceeding 20% at 10 years; previous stroke or transient ischaemic attack; heart failure; and stage 3-4 chronic kidney disease with proteinuria. Individuals most likely to be harmed from treating BP to target systolic < 140 mmHg are those who have no CV disease and aged over 80 years; moderate to severe frailty, cognitive impairment or functional limitations; labile BP and/or history of orthostatic hypotension, syncope and falls; or life expectancy < 12 months. Treatment should never be so intense as to reduce diastolic BP to < 60 mmHg in any older person. At a time when guidelines are calling for less conservative management of hypertension in all age groups, we contend that a more temperate approach, such as that offered here and based on the totality of available evidence, may assist in maximising net benefit in older patients.

Abstract
AIMS Several risk factors for incident heart failure (HF) have been previously identified, however large electronic health records (EHR) datasets may provide the opportunity to examine the consistency of risk factors across different subgroups from the general population. METHODS AND RESULTS We used linked EHR data from 2000 to 2010 as part of the UK-based CALIBER resource to select a cohort of 871 687 individuals 55 years or older and free of HF at baseline. The primary endpoint was the first record of HF from primary or secondary care. Cox proportional hazards analysis was used to estimate hazard ratios for associations between risk factors and incident HF, separately for men and women and by age category: 55-64, 65-74, and > 75 years. During 5.8 years of median follow-up, a total of 47 987 incident HF cases were recorded. Age, social deprivation, smoking, sedentary lifestyle, diabetes, atrial fibrillation, chronic obstructive pulmonary disease, body mass index, haemoglobin, total white blood cell count and creatinine were associated with HF. Smoking, atrial fibrillation and diabetes showed stronger associations with incident HF in women compared to men. CONCLUSION We confirmed associations of several risk factors with HF in this large population-based cohort across age and sex subgroups. Mainly modifiable risk factors and comorbidities are strongly associated with incident HF, highlighting the importance of preventive strategies targeting such risk factors for HF.

Abstract
Background Few data showed the optimal blood pressure (BP) in noncritically ill patients with acute kidney injury (AKI) relative to mortality or severe AKI. We therefore sought to analyze the data that exist for the ideal target range for BP in noncritically ill patients with AKI. Methods We performed a retrospective cohort study involving 1,612 hospitalized patients who were diagnosed with AKI using the Kidney Disease: Improving Global Outcomes definition based on serum creatinine measurements for a period of 1 year. The average systolic BP (SBP) was categorized into 10-mmHg increments (within 48 hours after the development of AKI). The primary outcome was a composite of severe AKI or 90-day mortality. Results The composite outcome rate in patients was 18.7% (302/1,612). The relationship between BP and the composite outcome followed a U-shaped curve, with an increased event rate observed at both low and high BP values. The average SBP after AKI predicted the composite outcome after adjusting for baseline variables (reference SBP: 120–129 mmHg; < 100 mmHg: hazard ratio [HR] 1.84, P = 0.015; 100–109 mmHg: HR 1.56, P = 0.038; 110–119 mmHg: HR 1.15, P = 0.483; 130–139 mmHg: HR 1.51, P = 0.045; ≥ 140 mmHg: HR 1.73, P = 0.005). Conclusion Among noncritically ill patients with AKI, a U-shaped curve association was observed between the average SBP within 48 hours after AKI and the composite primary outcome of this study, with the lowest event rate for SBP ranging from approximately 110 to 129 mmHg.

Abstract
OBJECTIVE To associate blood pressure (BP) documentation with adverse outcomes in an emergency department (ED). METHODS This is a retrospective observational study, and 642 records of patients admitted to the ED of a tertiary hospital in Brazil were used. We included medical records of patients of both sexes aged over 18 years, who were allocated in general wards in the period December 2015-June 2016. Association between BP measurements with length of stay (LOS), worsening of clinical presentation, unplanned patient transfer, readmission, stroke or transient ischemic attack, cardiorespiratory arrest, and death were investigated. RESULTS Association was observed between worsening of clinical presentation and systolic (p = 0.003) or diastolic (p = 0.001) BP values. The association between LOS and worsening of clinical presentation with the number of BP measurements or mean time between BP measurements was statistically significant (p < 0.001). Unplanned patient transfer was associated with an increase in the number of BP measurements (p < 0.001). The mean time between BP measurements was higher among patients who returned to the ED within 48-72 h (p = 0.030). CONCLUSIONS The results of this study showed association between BP documentation with adverse outcomes in the ED, reinforcing the need to develop educational strategies regarding nursing records and monitoring of vital signs.

Abstract
OBJECTIVE To determine the prevalence of hypotension and associated factors in hypertensive patients treated in the Primary Care setting. MATERIALS AND METHODS A cross-sectional, descriptive, and multicentre study was conducted with a total of 2635 general practitioners consecutively including 12,961 hypertensive patients treated in a Primary Care setting in Spain. An analysis was performed on the variables of age, gender, weight, height, body mass index, waist circumference, cardiovascular risk factors (diabetes, dyslipidaemia, smoking, obesity, sedentary lifestyle), fasting plasma glucose, complete lipid profile, as well as the presence of target organ damage (left ventricular hypertrophy, microalbuminuria, carotid atherosclerosis) and associated clinical conditions. Hypotension was defined as a systolic blood pressure less than 110mmHg or a diastolic blood pressure less than 70mmHg. A multivariate analysis was performed to determine the variables associated with the presence of hypotension. RESULTS The mean age was 66.2 years, and 51.7% of patients were women. The mean time of onset of hypertension was 9.1 years. A total of 13.1% of patients (95% confidence interval 12.4-13.6%) had hypotension, 95% of whom had low diastolic blood pressure. The prevalence of hypotension was higher in elderly patients (25.7%) and in those individuals with coronary heart disease (22.6%). The variables associated with the presence of hypotension included a history of cardiovascular disease, being treated with at least 3 antihypertensive drugs, diabetes, and age. CONCLUSIONS One out of 4-5 elderly patients, or those with cardiovascular disease, had hypotension. General practitioners should identify these patients in order to determine the causes and adjust treatment to avoid complications.

Abstract
BACKGROUND Blood pressure (BP) and cholesterol are major modifiable risk factors for cardiovascular disease (CVD), but effects of exposures during young adulthood on later life CVD risk have not been well quantified. OBJECTIVE The authors sought to evaluate the independent associations between young adult exposures to risk factors and later life CVD risk, accounting for later life exposures. METHODS The authors pooled data from 6 U.S. cohorts with observations spanning the life course from young adulthood to later life, and imputed risk factor trajectories for low-density lipoprotein (LDL) and high-density lipoprotein cholesterols, systolic and diastolic BP starting from age 18 years for every participant. Time-weighted average exposures to each risk factor during young (age 18 to 39 years) and later adulthood (age ≥40 years) were calculated and linked to subsequent risks of coronary heart disease (CHD), heart failure (HF), or stroke. RESULTS A total of 36,030 participants were included. During a median follow-up of 17 years, there were 4,570 CHD, 5,119 HF, and 2,862 stroke events. When young and later adult risk factors were considered jointly in the model, young adult LDL ≥100 mg/dl (compared with <100 mg/dl) was associated with a 64% increased risk for CHD, independent of later adult exposures. Similarly, young adult SBP ≥130 mm Hg (compared with <120 mm Hg) was associated with a 37% increased risk for HF, and young adult DBP ≥80 mm Hg (compared with <80 mm Hg) was associated with a 21% increased risk. CONCLUSIONS Cumulative young adult exposures to elevated systolic BP, diastolic BP and LDL were associated with increased CVD risks in later life, independent of later adult exposures.
