Arterial stiffness, assessed through pulse wave velocity (PWV), independently predicts cardiovascular outcomes. In untreated persons, white-coat hypertension (WCH) has been related to arterial stiffness, but data in treated patients with WCH are scarce. The authors aimed to determine a possible association between WCH and arterial stiffness in this population. Adult treated hypertensive patients underwent home blood pressure monitoring and PWV assessment. Variables associated with PWV in univariable analyses were entered into a multivariable linear regression model. The study included 121 patients, 33.9% men, median age 67.9 (interquartile range 18.4) years, 5.8% with diabetes, and 3.3% with a history of cardiovascular or cerebrovascular disease. In multivariable analysis, WCH in treated hypertensive patients remained a determinant of PWV: β=1.1 (95% confidence interval, 0.1-2.1 [P=.037]; adjusted R2 0.49). In conclusion, WCH is independently associated with arterial stiffness in treated hypertensive patients. Whether this high-risk association is offset by antihypertensive treatment should be further investigated. [ABSTRACT FROM AUTHOR]

- Abstract
Background: An alerting reaction is a physician-induced phenomenon which produces a transient blood pressure rise in the office. Objective: To determine its relationship with target organ damage in treated hypertensives. Method: We used three different indexes for calculating alerting reaction depending on the first, second or third office blood pressure measurement. We correlated these indexes with glomerular filtration rate, left ventricular mass index and pulse wave velocity. Thereafter, for multivariate analysis, we selected the index which better correlated with each target organ damage subtype. Results: We included 174 adults, mean age 67(±13.7) years. 75% of the patients had some degree of blood pressure fall between measurements 1-3. In multivariate linear regression models, after adjusting for classic risk factors, two out of the three systolic alerting reaction indexes showed an independent association with target organ damage. After further adjusting for office blood pressure and white coat effect (calculated with standardized home blood pressure monitoring), left ventricular mass index maintained a statistically significant association. Conclusion: A higher alerting reaction in the office seems to be related to increased target organ damage in treated hypertensives and should not be considered an innocent phenomenon.

We aimed to determine a possible association between isolated morning hypertension (IMH) and meal-induced blood pressure (BP) fall in adult treated hypertensive patients who underwent home BP measurements. A total of 230 patients were included, median age 73.6, 65.2% women. After adjusting for age, sex, number of antihypertensive drugs, office and home BP levels, the association between IMH and meal-induced BP fall was statistically significant. In conclusion, meal-induced BP fall and IMH detected through home blood pressure monitoring (HBPM) are independently associated in hypertensive patients. The therapeutic implications of such observation need to be clarified in large-scale prospective studies. [ABSTRACT FROM AUTHOR]

58. Challenges associated with peripheral arterial disease in women.

- Abstract
Peripheral arterial disease (PAD) is an increasingly recognized disorder that is associated with functional impairment, quality-of-life deterioration, increased risk of cardiovascular ischemic events, and increased risk of total and cardiovascular mortality. Although earlier studies suggested that PAD was more common in men, recent reports based on more sensitive tests have shown that the prevalence of PAD in women is at least the same as in men, if not higher. PAD tends to present itself asymptomatically or with atypical symptoms more frequently in women than in men, and is associated with comorbidities or situations particularly or exclusively found in the female sex, such as osteoporosis, hypothyroidism, the use of oral contraceptives, and a history of complications during pregnancy. Fat-distribution patterns and differential vascular characteristics in women may influence the interpretation of diagnostic methods, whereas sex-related vulnerability to drugs typically used in subjects with PAD, differences in risk-factor distribution among sexes, and distinct responses to revascularization procedures in men and women must be taken into account for proper disease management. All these issues pose important challenges associated with PAD in women. Of note, this group has classically been underrepresented in research studies. As a consequence, several sex-related challenges regarding diagnosis and management issues should be acknowledged, and research gaps should be addressed in order to successfully deal with this major health issue.

The prognostic value of impedance cardiography (ICG; cardiac index [CI] and systemic vascular resistance index [SVRI] were measured) was assessed in this retrospective cohort study. A total of 1151 hypertensive outpatients >50 years with a baseline ICG were included. After median follow-up of 3.9 years, for the composite endpoint of cardiovascular events and stroke, adjusted HR for each 500 ml/min/m
2 CI increase was 0.85 (CI95% 0.73-0.9, p = 0.039), and for each 500 dynes s cm−5 SVRI increase was 1.11 (CI95% 1.01-1.23, p = 0.046), whereas adjusted HR for all-cause mortality was not significant. ICG adds prognostic value to conventional risk factors in hypertensive patients. [ABSTRACT FROM AUTHOR]- Published

- Abstract
AbstractBackground:Longitudinal studies have demonstrated that the risk of cardiovascular disease increases with pulse pressure (PP). However, PP remains an elusive cardiovascular risk factor with findings being inconsistent between studies. The 2013 ESH/ESC guideline proposed that PP is useful in stratification and suggested a threshold of 60 mm Hg, which is 10 mm Hg higher compared to that in the 2007 guideline; however, no justification for this increase was provided. Methodology:Published thresholds of PP are based on office blood pressure measurement and often on arbitrary categorical analyses. In the International Database on Ambulatory blood pressure in relation to Cardiovascular Outcomes (IDACO) and the International Database on HOme blood pressure in relation to Cardiovascular Outcome (IDHOCO), we determined outcome-driven thresholds for PP based on ambulatory or home blood pressure measurement, respectively. Results:The main findings were that for people aged <60 years, PP did not refine risk stratification, whereas in older people the thresholds were 64 and 76 mm Hg for the ambulatory and home PP, respectively. However, PP provided little added predictive value over and beyond classical risk factors.© 2014 S. Karger AG, Basel

We assessed prevalence and clinical characteristics of resistant hypertension (RH) and prevalence of false RH (white-coat effect [WCE] by home blood pressure [BP] monitoring), among a population of 302 treated hypertensive patients, mean age 66.6 (±13.8), 67.5% women. Resistant hypertension was defined according to the American Heart Association criteria. Prevalence of RH was 10%, and the following five variables were independently associated with it: body mass index, diabetes, isolated systolic hypertension, orthostatic hypotension, and use of beta-blockers. Prevalence of WCE among subjects with office-RH was 27.6%. Our study identified easily measurable parameters related to RH. Standing BP should be systematically measured in individuals with RH.

BACKGROUND Masked hypertension (MH) entails an increased cardiovascular risk. Therefore, it is important to identify those individuals who would benefit the most from out-of-office blood pressure (BP) measurement. We sought to determine the prevalence and identify predictors of MH among adult hypertensive patients under treatment. METHODS Treated hypertensive patients aged ≥ 18 years underwent office (duplicate sitting and standing BP in 1 visit) and home BP measurements (duplicate measurements for 4 days in the morning, afternoon, and evening; at least 16 measurements) and completed a questionnaire regarding risk factors and history of cardiovascular disease. MH was defined as normal office BP (<140/90mm Hg) with elevated home BP (≥135/85mm Hg, average of all readings discarding first day measurements). Patients with a systolic BP rise upon standing ≥5mm Hg were considered to have orthostatic hypertension (OHT). Variables indentified as relevant predictors of MH were entered into a multivariable logistic regression analysis model. RESULTS Three hundred and four patients were included (mean age = 66.7 ±13.8; 67.4% women). The prevalence of MH in the whole population was 12.4% and was 20.9% among patients with office-controlled hypertension. Factors independently associated with MH were age (odds ratio (OR) = 1.08, 95% confidence interval (CI) = 1.03–1.14), high-normal office systolic BP (OR = 5.61, 95% CI = 1.39–22.57), history of peripheral artery disease (PAD) (OR = 8.83, 95% CI = 1.5–51.84), moderate alcohol consumption (OR = 0.08, 95% CI = 0.01–0.73), and OHT (OR = 3.65, 95% CI = 1.27 to 10.51). CONCLUSIONS Easily measurable parameters such as age, office systolic BP, history of PAD, and OHT may help to detect a population at risk of MH that would benefit from home BP monitoring.

- Abstract
Prognostic significance of the timing in the cardiac cycle of the first (TP1) and second (TP2) systolic peak of the central aortic pulse wave is ill-defined. Incidence rates and standardized multivariable-adjusted hazard ratios (HRs) of adverse health outcomes associated with TP1 and TP2, estimated by the SphygmoCor software, were assessed in the International Database of Central Arterial Properties for Risk Stratification (IDCARS) (n = 5529). Model refinement was assessed by the integrated discrimination (ID) and net reclassification (NR) improvement. Over 4.1 years (median), 201 participants died and 248 and 159 patients experienced cardiovascular or cardiac endpoints. Mean TP1 and TP2, standardized for cohort, sex, age, and heart rate, were 103 and 228 ms. Shorter TP1 and TP2 were associated with higher mortality and shorter TP1 with a higher risk of cardiovascular and cardiac endpoints (trend p ≤ 0.004). The HRs relating total mortality and cardiovascular endpoints to TP2 were 0.82 (95% confidence interval [CI]: 0.72-0.94) and 0.87 (0.77-0.98), respectively. The HR relating cardiac endpoints to TP1 was 0.81 (0.68-0.97). For total mortality and cardiovascular endpoints in relation to TP2, NRI was significant (p ≤ 0.010), but not for cardiac endpoints in relation to TP1. Integrated discrimination improvement (IDI) was not significant for any endpoint. The HRs relating total mortality to TP2 were smaller (p ≤ 0.026) in women than men (0.67 vs. 0.95) and in older (≥ 60 years) versus younger (< 60 years) participants (0.80 vs. 0.88). Our study adds to the evidence supporting risk stratification based on aortic pulse analysis by showing that TP2 and TP1 carry prognostic information., (© 2025 The Author(s).

- Abstract
Background: Aortic pulse wave velocity (PWV) predicts cardiovascular events (CVEs) and total mortality (TM), but previous studies proposing actionable PWV thresholds have limited generalizability. This individual-participant meta-analysis is aimed at defining, testing calibration, and validating an outcome-driven threshold for PWV, using 2 populations studies, respectively, for derivation IDCARS (International Database of Central Arterial Properties for Risk Stratification) and replication MONICA (Monitoring of Trends and Determinants in Cardiovascular Disease Health Survey - Copenhagen)., Methods: A risk-carrying PWV threshold for CVE and TM was defined by multivariable Cox regression, using stepwise increasing PWV thresholds and by determining the threshold yielding a 5-year risk equivalent with systolic blood pressure of 140 mm Hg. The predictive performance of the PWV threshold was assessed by computing the integrated discrimination improvement and the net reclassification improvement., Results: In well-calibrated models in IDCARS, the risk-carrying PWV thresholds converged at 9 m/s (10 m/s considering the anatomic pulse wave travel distance). With full adjustments applied, the threshold predicted CVE (hazard ratio [CI]: 1.68 [1.15-2.45]) and TM (1.61 [1.01-2.55]) in IDCARS and in MONICA (1.40 [1.09-1.79] and 1.55 [1.23-1.95]). In IDCARS and MONICA, the predictive accuracy of the threshold for both end points was ≈0.75. Integrated discrimination improvement was significant for TM in IDCARS and for both TM and CVE in MONICA, whereas net reclassification improvement was not for any outcome., Conclusions: PWV integrates multiple risk factors into a single variable and might replace a large panel of traditional risk factors. Exceeding the outcome-driven PWV threshold should motivate clinicians to stringent management of risk factors, in particular hypertension, which over a person's lifetime causes stiffening of the elastic arteries as waypoint to CVE and death., Competing Interests: Disclosures None.

- Abstract
Objective: To address to what extent central hemodynamic measurements, improve risk stratification, and determine outcome-based diagnostic thresholds, we constructed the International Database of Central Arterial Properties for Risk Stratification (IDCARS), allowing a participant-level meta-analysis. The purpose of this article was to describe the characteristics of IDCARS participants and to highlight research perspectives., Methods: Longitudinal or cross-sectional cohort studies with central blood pressure measured with the SphygmoCor devices and software were included., Results: The database included 10,930 subjects (54.8% women; median age 46.0 years) from 13 studies in Europe, Africa, Asia, and South America. The prevalence of office hypertension was 4,446 (40.1%), of which 2,713 (61.0%) were treated, and of diabetes mellitus was 629 (5.8%). The peripheral and central systolic/diastolic blood pressure averaged 129.5/78.7 mm Hg and 118.2/79.7 mm Hg, respectively. Mean aortic pulse wave velocity was 7.3 m per seconds. Among 6,871 participants enrolled in 9 longitudinal studies, the median follow-up was 4.2 years (5th-95th percentile interval, 1.3-12.2 years). During 38,957 person-years of follow-up, 339 participants experienced a composite cardiovascular event and 212 died, 67 of cardiovascular disease., Conclusions: IDCARS will provide a unique opportunity to investigate hypotheses on central hemodynamic measurements that could not reliably be studied in individual studies. The results of these analyses might inform guidelines and be of help to clinicians involved in the management of patients with suspected or established hypertension., (© The Author(s) 2021.

- Abstract
Unlabelled: The morning blood pressure (BP) rise entails a higher cardiovascular risk. Studies evaluating the association between home BP morning rise and target organ damage are scarce and almost exclusively based on Asians. The aim of our study was to characterize hypertensive patients with morning rise in home BP and to establish a possible association with left ventricular hypertrophy (LVH)., Methods: treated hypertensive patients ≥ 18 years underwent home BP measurements (duplicate measurements for 4 days in the morning, afternoon and evening), and completed a questionnaire regarding risk factors and history of cardiovascular disease. Medical records were reviewed to extract data from grams. A morning rise in systolic home BP was defined as a difference between morning and evening systolic BP averages ≥15 mmHg. Subjects were considered to have LVH if the left ventricular mass index was >95 g/m2 in women and >115 g/m2 in men. Variables identified as relevant predictors of home BP morning rise were entered into a multivariable logistic regression analysis model., Results: 216 patients were included, mean age 68 (+13.3), 69.4% women and 99.1% Caucasians. The prevalence of BP morning rise was 13.4% and independently associated factors were LVH (OR 3.5; 95%CI 1.1-11.4), age (OR 1.05; 95%CI 1.003-1.1) and a history of cerebrovascular disease (OR 3.9; 95%CI 1.1-14.2). In conclusion, a morning rise in systolic BP detected through home BP monitoring is independently associated with LVH, age and a history of cerebrovascular disease. The therapeutic implications of this observation need to be clarified in large-scale prospective studies.

- Abstract
HBPM guidelines state that morning and evening measurements should be recorded and, to improve stability, the first day of measurements should be discarded. Our objective was to assess the reproducibility and reliability of a 4-day HBPM protocol with and without first day measurements. We analyzed a retrospective cohort of ambulatory patients who required a HBPM for diagnostic purposes or evaluation of treatment efficacy. A 4-day protocol was implemented, with daily duplicate measurements in the morning, afternoon and evening, using an OMRON 705 CP validated equipment. HBPM reproducibility was quantified by test-re-test correlations and standard deviation of differences (SDD) between BP measurements obtained during the entire 4 days, with and without exclusion of the first day. The reliability criterion was the stabilization of the mean and standard deviation (SD). We included 353 subjects with a total of 8224 BP recordings (median of 24 recordings per patient). We found a strong test-re-test correlation between days 1 to 4, which improved when we excluded the first day (p<0.001). We also found a reduction of the mean BP when we increased the number of days and a reduction of SDD when we excluded day 1. Therefore, we conclude that the exclusion of the first day of measurements improves the reproducibility and reliability of a 4-day protocol, and such two factors are not affected by the inclusion of afternoon measurements.
