Ambulatory Blood Pressure Phenotypes, Arterial Stiffness And Cardiac Remodelling.

BACKGROUND: Evidence on the association of arterial stiffness and left ventricular (LV) concentric remodelling/ LVH assessed by echocardiography, with abnormal blood pressure (BP) phenotypes, defined by office and ambulatory BP monitoring (ABPM) in the community is scanty. We investigated this issue in the participants to the Pressioni Monitorate E Loro Associazioni (PAMELA) study. METHODS: The study included 491 participants who attended the second and third survey of the PAMELA study performed after 10 and 25 years from the initial evaluation. Data collection included medical history, anthropometric parameters, blood examinations, office, ABPM, echocardiographic and Cardio-Ankle Vascular Index (CAVI) measurements. RESULTS: In the whole study sample (age 66 + 10 years, 50% males), the prevalence rates of sustained normotension (NT), white coat hypertension (WCH), masked hypertension (MH), sustained hypertension (SH) and non-dipping (ND) were 31.2, 10.0, 24.2, 34.6, and 35.8% and respectively. The likelihood of having SH, the BP phenotype carrying the greatest CV risk, was four times higher (OR= 4.31, CI:2.39-7.76, p<0.0001) in participants with increased CAVI and LV remodelling/LVH compared to their counterparts without organ damage. This association showed an incremental value in discriminating SH compared to both isolated markers of organ damage (OR=1.92,p=0.03 for increased CAVI and OR= 2.02, p=0.02 for LV remodelling/LVH). The presence of isolated but also combined organ damage was unrelated to ND. CONCLUSIONS: Our study provides new evidence of the incremental value of looking for both vascular and cardiac organ damage to optimize the identification and clinical management of SH in the general population.

Cardio-Ankle Vascular Index and left ventricular mass as markers of nocturnal blood pressure fall in the general population.

BACKGROUND: Findings regarding the association between Cardio-Ankle Vascular Index (CAVI) and the extent of nocturnal blood pressure (BP) fall in the general population are scanty. We sought to investigate this issue in the participants enrolled in the Pressioni Monitorate E Loro Associazioni (PAMELA) study. METHODS: The study included 491 participants who attended the second and third surveys of the PAMELA study performed after 10 and 25 years from the initial evaluation. Data collection included medical history, anthropometric parameters, office, home, ambulatory blood pressure BP monitoring (ABPM), blood examinations, echocardiography, and CAVI measurements. RESULTS: In the whole study, both CAVI and left ventricular mass index (LVMI) were inversely correlated with nocturnal SBP fall, expressed as day-night percent change (r = - 0.152, p = 0.0007, and r = - 0.213, p < 0.0001, respectively). However, after adjustment for sex and age, the correlation remained significant only for LVMI (r = - 0.124, p = 0.006). Non-dipper participants exhibited significantly higher sex-age adjusted LVMI (91 ± 22 vs 82 ± 18 g/m2 (p < 0.0001)), but not of CAVI (9.07 ± 2.0 and 9.57 ± 2.2 m/s, p = ns). Similar results were found when classifying participants into quartiles of nocturnal SBP drop. Finally, both sex-age adjusted CAVI and LVMI were positively correlated with mean nocturnal SBP (r = 0.181, p < 0.001, and r = 0.240, p < 0.0001). CONCLUSIONS: Although arterial stiffness assessed by CAVI, unlike LVMI, is unrelated with the degree of nocturnal BP drop, this marker is useful in identifying nocturnal hypertension and optimizing cardiovascular risk stratification in the community.

Habitual Regular Coffee Consumption and Arterial Stiffness: Data From the 3rd Pamela Survey.

BACKGROUND: We evaluated whether chronic coffee consumption affects arterial stiffness, assessed by cardio-ankle vascular index (CAVI). METHODS: In 514 subjects, aged 66.6 ±â€…9.9 years (mean ±â€…SD), recruited in the 3rd follow-up of the PAMELA study, subdivided into 3 groups according to the daily intake of regular coffee (0, 1-2, and ≥3 cups/day), we measured CAVI and clinic, ambulatory blood pressure (BP), and other variables. RESULTS: The 3 groups displayed similar age, gender, metabolic, and renal profile. Clinic and ambulatory BPs were similar in the 3 groups, this being the case for CAVI (0 cup: 9.1 ±â€…1.8, 1-2 cups: 9.5 ±â€…2.3, and ≥3 cups: 9.2 ±â€…2.1 m/s, P = NS). No significant gender difference in CAVI and in participants under antihypertensive treatment was detected. CONCLUSIONS: Our data show that chronic coffee consumption leaves unaffected arterial stiffness in the general population, this being the case in subgroups. The neutral vascular impact of coffee may favor the absence of any significant BP effect of habitual coffee intake.

Habitual coffee consumption and office, home, and ambulatory blood pressure: results of a 10-year prospective study.

OBJECTIVES: Heterogeneous are the results of the published studies aimed at determining the long-term effects of habitual coffee consumption on blood pressure (BP). Specifically, no data are available on the longitudinal association between habitual coffee consumption and office, home and 24 h BP profile and variability. METHODS: In 1408 subjects recruited in the Pressioni Arteriose Monitorate E Loro Associazioni (PAMELA) study, followed for a 10 year follow-up period and classified as coffee consumers and nonconsumers (self-reporting), we prospectically investigated the association between habitual coffee consumption and office, home and 24-h ambulatory BP; 24-h BP variability; and development of a new hypertensive state. Data were also analysed according to gender. RESULTS: When data were adjusted for confounders habitual coffee nonconsumers and consumers displayed similar long-term BP changes during the follow-up in office, home, and ambulatory BP. No difference was found between heavy and moderate coffee consumers. Furthermore, also new-onset hypertension and patterns of BP variability were superimposable in coffee nonconsumers and consumers, independently on confounders including gender, number, and characteristics of the antihypertensive drug treatment. CONCLUSION: The present study, which is the first longitudinal investigation never performed examining in a prospective fashion the long-term (10 year) effects of coffee consumption on office, home, and ambulatory BP, provides conclusive evidence that habitual coffee consumption is associated with neutral effects on in-office and out-of-office BP values and related variabilities. This is the also the case for the new-onset hypertensive state.

Cardio-Ankle Vascular Index as a Marker of Left Ventricular Hypertrophy in Treated Hypertensives: Findings From the Pamela Study.

BACKGROUND: Findings regarding the association between Cardio-Ankle Vascular Index (CAVI) and cardiac hypertension-mediated organ damage (HMOD), such as left ventricular hypertrophy (LVH) assessed by echocardiography, in elderly hypertensive patients are scanty. We sought to investigate this issue in the hypertensive fraction of the general population treated with anti-hypertensive drugs enrolled in the Pressioni Monitorate E Loro Associazioni (PAMELA) study. METHODS: The study included 239 out of 562 participants who attended the second and third surveys of the PAMELA study performed after 10 and 25 years from the initial evaluation. Data collection included medical history, anthropometric parameters, office, home, ambulatory blood pressure (BP), blood examinations, echocardiography, and CAVI measurements. RESULTS: In the whole study sample (age 69 ±â€…9 years, 54% males), CAVI was positively correlated with age, office, home, ambulatory systolic BP, LV mass (LVM) index, and negatively associated with body mass index (BMI). In multivariate analysis, CAVI was associated with the LVM index (P < 0.05) independently of major confounders. The participants with LVH exhibited significantly higher CAVI (10.6 ±â€…2.8 vs. 9.2 ±â€…1.8 m/s P < 0.001), larger left atrial diameter, and lower LV ejection fraction values than their counterparts without it. The CAVI value of 9.4 m/s was the best cut-off for prediction of LVH in the whole sample. CONCLUSIONS: Our study provides new evidence of an independent association between CAVI and LVH in treated elderly hypertensive patients and suggests that the use of this metric of arterial stiffness could not only be used to evaluate vascular damage but also to stratify the risk of LVH.

Long-term increase in serum uric acid and its predictors over a 25 year follow-up: Results of the PAMELA study.

BACKGROUND AND AIMS: Hyperuricemia (HU) has been shown to be associated with an adverse impact on cardiovascular and metabolic risk. Scanty data are available in the general population on the longitudinal changes in serum uric acid (SUA), the occurrence of HU and their potential predictors. We examined during a 25-year follow-up the SUA changes and the factors associated with HU development in the Pressioni Arteriose Monitorate E loro Associazioni (PAMELA) study. METHODS AND RESULTS: We analyzed data collected in 561 subjects of the PAMELA study evaluated during an average follow-up time amounting to 25.4 ± 1.0 years (mean ± SD). HU was defined by the Uric Acid Right for Heart Health (URRAh) cutoff (5.1 for females and 5.6 mg/dl for males). Mean SUA values during follow-up increased from 4.7 ± 1.1 to 5.0 ± 1.2 mg/dl (P<0.001), the average SUA elevation amounting to of 0.3 ± 1.1 mg/dl 26.7 % of the subjects displayed HU at the follow-up. This was associated at the multivariable analysis with female gender, office, home and 24-h blood pressure, diuretic treatment, serum triglycerides and baseline SUA, as well as the increase in waist circumference and the reduction in renal function. CONCLUSION: The present study provides longitudinal evidence that in the general population during a 25 year follow-up there is a progressive increase in SUA and HU development. Baseline SUA represents the most important factor associated with these modifications. Gender, renal dysfunction, triglycerides, obesity, diuretic treatment and blood pressure represent other variables capable to predict future occurrence of HU.

Comparison between visit-to-visit office and 24-h blood pressure variability in treated hypertensive patients.

OBJECTIVES: In any treated hypertensive patient office blood pressure (BP) values may differ between visits and this variability (V) has an adverse prognostic impact. However, little information is available on visit-to-visit 24-h BPV. METHODS: In 1114 hypertensives of the ELSA and PHYLLIS trials we compared visit-to-visit office and 24-h mean BPV by coefficient of variation (CV) of the mean systolic (S) and diastolic (D) BP obtained from yearly measurements during a 3-4 year treatment period. Visit-to-visit BPV during daytime and night-time were also compared. RESULTS: Twenty-four-hour SBP-CV was about 20% less than office SBP-CV ( P  < 0.0001). SBP-CV was considerably greater for the night-time than for the daytime period (20%, P  < 0.0001). Results were similar for DBP and in males and females, older and younger patients, patients under different antihypertensive drugs or with different baseline or achieved BP values. In the group as a whole and in subgroups there was significant correlations between office and 24-h BP-CV but the correlation coefficients was weak, indicating that office SBP or DBP CV accounted for only about 1-4% of 24-h SBP or DBP-CV values. CONCLUSION: Twenty-four-hour mean BP across visits is more stable than across visit office BP. Visit-to-visit office and 24-h BPV are significantly related to each other, but correlation coefficients are low, making visit-to-visit office BP variations poorly predictive of the concomitant 24-h BP variations and thus of on-treatment ambulatory BP stability.

The psychosocial impact of haemophilia from patients' and caregivers' point of view: The results of an Italian survey.

BACKGROUD: A huge amount of data about psychosocial issues of people with haemophilia (PwH) are available; however, these materials are fragmentary and largely outdated, failing to reflect the impact of current treatment strategies. AIM: Describing the influence of illness on psychosocial aspects of adult PwH (≥18 years) and caregivers of children with haemophilia (CPwH) without inhibitors, in Italy. METHODS: Surveys (for adult PwH, CPwH and haemophilia specialists) were developed by a multidisciplinary working group and conducted from November 2019 to June 2020. RESULTS: A total of 120 PwH without inhibitors and 79 CPwH completed the survey. Adult patients reported a significant impairment in many psychosocial aspects, including working activities, relations with family members and social relations. Caregivers generally reported better scores in all aspects of the survey. Mobility, Pain and Mental health domains of EQ-5D were the most frequently impaired in both patients and caregivers, reducing the perceived quality of life. Genetic counselling was an important issue, 53% of CPwH declaring unawareness of their carrier status, as well as the psychological support offered by the reference center, 67.0% of respondents reporting that no psychological support was provided at the time of diagnosis communication. CONCLUSION: This study provides information about PwH's and CPwH's point of view in the current scenario of continuous innovations in haemophilia treatment and management furthermore, updated insights on psychosocial problems faced by patients and caregivers are reported.

The Results of the URRAH (Uric Acid Right for Heart Health) Project: A Focus on Hyperuricemia in Relation to Cardiovascular and Kidney Disease and its Role in Metabolic Dysregulation.

The relationship between Serum Uric Acid (UA) and Cardiovascular (CV) diseases has already been extensively evaluated, and it was found to be an independent predictor of all-cause and cardiovascular mortality but also acute coronary syndrome, stroke and heart failure. Similarly, also many papers have been published on the association between UA and kidney function, while less is known on the role of UA in metabolic derangement and, particularly, in metabolic syndrome. Despite the substantial number of publications on the topic, there are still some elements of doubt: (1) the better cut-off to be used to refine CV risk (also called CV cut-off); (2) the needing for a correction of UA values for kidney function; and (3) the better definition of its role in metabolic syndrome: is UA simply a marker, a bystander or a key pathological element of metabolic dysregulation?. The Uric acid Right for heArt Health (URRAH) project was designed by the Working Group on uric acid and CV risk of the Italian Society of Hypertension to answer the first question. After the first papers that individuates specific cut-off for different CV disease, subsequent articles have been published responding to the other relevant questions. This review will summarise most of the results obtained so far from the URRAH research project.

Anthropometric Measures of Adiposity as Markers of Kidney Dysfunction: A Cross-Sectional Study.

The present study was designed to provide information on the ability of several different anthropometric markers to reflect the renal impairment associated with body weight increase and to predict the development of renal alterations linked to overweight and obesity. In 574 subjects representative of the general population of the Pressioni Arteriose Monitorate e Loro Associazioni (PAMELA) study, with an age range between 57 and 73 years, we investigated the association between different anthropometric markers of body fat, as alternative to body mass index, and renal failure, to obtain information useful for determining their potential predictive value. Renal dysfunction was significantly associated with almost all anthropometric markers of adiposity related to body weight and body shape. After adjustment for confounders, such as age, sex, office blood pressure, serum glucose, antihypertensive drugs and smoking habit, association remained significant only for waist-to-hip ratio (WHR), lipid accumulation product (LAP) and visceral adiposity index (VAI). These 3 markers also displayed at the receiver operating curves (ROC) analysis the best ability to detect subjects with or without kidney dysfunction. The results of the present study provide evidence that WHR, LAP and VAI represent the best markers of renal dysfunction associated with visceral body fat accumulation.

Coffee consumption, clinic, 24-hour and home blood pressure. Findings from the PAMELA study.

BACKGROUND AND AIMS: Chronic coffee consuption has been reported to be associated with a modest but significant increase in blood pressure (BP), although some recent studies have shown the opposite. These data, however, largely refer to clinic BP and virtually no study evaluated cross-sectionally the association between chronic coffee consuption, out-of-office BP and BP variability. METHODS AND RESULTS: In 2045 subjects belonging to the population of the Pressioni Arteriose Monitorate E Loro Associazioni (PAMELA) study, we analyzed cross-sectionally the association between clinic, 24-hour, home BP and BP variability and level of chronic coffee consumption. Results show that when adjusted for confounders (age, gender, body mass index, cigarette smoking, physical activity and alcohol drinking) chronic coffee consumption does not appear to have any major lowering effect on BP values, particulary when they are assessed via 24-hour ambulatory (0 Cup/day: 118.5 ± 0.7/72.8 ± 0.4 mmHg vs 3 cups/day: 120.2 ± 0.4/74.8 ± 0.3 mmHg, PNS) or home BP monitoring (0 cup/day: 124.1 ± 1.2/75.4 ± 0.7 mmHg vs 3 cups/day: 123.3 ± 0.6/76.4 ± 0.36 mmHg, PNS). However, daytime BP was significantly higher in coffee consumers (about 2 mmHg), suggesting some pressor effects of coffee which vanish during nighttime. Both BP and HR 24-hour HR variability were unaffected. CONCLUSION: Thus chronic coffee consumption does not appear to have any major lowering effect either on absolute BP values, particulary when they are assessed via 24-hour ambulatory or home BP monitoring, or on 24-hour BP variability.

Impact of the Increase in Left Ventricular Mass on the Risk of Long-Term Cardiovascular Mortality: A Prospective Cohort Study.

BACKGROUND: Left ventricular hypertrophy (LVH) is an independent predictor of cardiovascular events, and evidence has been obtained that an increase of a normal left ventricular mass (LVM) or new-onset LVH over time augments cardiovascular outcomes. METHODS: We addressed this issue in a sample of a general population at relatively low cardiovascular risk. We analyzed subjects with normal echocardiographic LVM enrolled in the PAMELA (Pressioni Arteriose Monitorate E Loro Associazioni) study to follow the increase of LVM over time and assess the prognostic impact of this change on the incidence of cardiovascular events (mean follow-up 18.5 years). RESULTS: In 990 subjects with no LVH at baseline, there was a significant average increase of LVM (21.2%), LVMIBSA (18.9%), and LVMIHT (22.3%) more than 10 years later. About a quarter developed LVH. The LVMIBSA change exhibited an association with the cardiovascular risk mortality during the following 18.5 years, and the association remained significant after adjustment for confounders (hazard ratio, 1.2 [1.0-1.5]). Similar findings were obtained for LVM in absolute values or indexed for height. The association was seen in both genders, but the link with the cardiovascular risk was statistically significant in males only. CONCLUSIONS: Thus, although over 10 years, the LVM increase does not reach a LVH status, it is associated with an augmented cardiovascular mortality risk. This suggests that it might be important to consider periodical LVM assessment, even when LVM is within the normal range, to timely detect its increase and cope with the need of cardiovascular risk restratification.

Comparison of electrocardiographic versus echocardiographic detection of left ventricular mass changes over time and evaluation of new onset left ventricular hypertrophy.

We assessed the value of 3 electrocardiographic (EKG) voltage criteria in detecting variations of left ventricular mass (LVM) over time, taking echocardiographic (ECHO) LVM as reference, in the Pressioni Arteriose Monitorate E Loro Associazioni study. In 927 subjects (age 47 ± 13 years on entry, 49.9% men) an ECHO evaluation of LVM and EKG suitable for measurement of EKG-LVH criteria (Sokolow-Lyon voltage, Cornell voltage and R-wave voltage in aVL) were available at baseline and at a 2nd evaluation performed 10 years later. Δ (delta) LVM, Δ LVMI, and Δ EKG parameters values were calculated from 2nd evaluation to baseline. The sensitivity of the EKG criteria in the diagnosis of LVH, poor at baseline, becomes even worse after 10 years, reaching very low values. Only the sensitivity of R-wave amplitude exhibited slight increase over time but with unsatisfactory absolute values. Despite the prevalence of ECHO-LVH at the 2nd evaluation was threefold increased compared to baseline (29.3% and 33.7% for LVM indexed to BSA and height2.7 , respectively), the prevalence of EKG-LVH was unchanged when evaluated by Sokolow-Lyon criteria, significantly reduced when assessed by Cornell voltage index, while significantly increased using R-wave voltage in aVL criteria. Despite an ECHO-LVM increase over the time, mean EKG changes were of opposite sign, except for R-wave amplitude in aVL. Our study highlights the discrepancy between ECHO and EKG in monitoring LVM changes over the time, especially for Sokolow-Lyon and Cornell voltage. Thus, EKG is an unsuitable method for the longitudinal evaluation of LVM variations.

Uric acid relationships with lipid profile and adiposity indices: Impact of different hyperuricemic thresholds.

Previous studies focused on the relationships between Serum Uric Acid (SUA) and lipids have found an association mainly with triglycerides. Furthermore, previous studies on adiposity indices have been focused on the evaluation of the Visceral Adiposity Index (VAI). The present study was aimed at providing within the same population a systematic evaluation of lipids and adiposity indices with SUA, employing both the classic cutoff for hyperuricemia and the newly one identified by the Uric Acid Right for Heart Health (URRAH) study. We analyzed data collected in 1892 subjects of the Pressioni Arteriose Monitorate E loro Associazioni (PAMELA) study with available SUA, lipid profile and variables necessary to calculate VAI, Cardio-Metabolic Index (CMI) and Lipid Accumulation Product (LAP). At linear regression model (corrected for confounders) SUA correlated with all the lipids values (with the strongest ß for triglycerides) and adiposity indices. When the two different cutoffs were compared, the URRAH one was significantly related to atherogenic lipids profile (OR 1.207 for LDL and 1.33 for non-HDL, P < 0.001) while this was not the case for the classic one. Regarding adiposity indices the classic cutoff displays highest OR as compared to the URRAH one. In conclusions, newly reported URRAH cutoff for hyperuricemia better relate to atherogenic lipoprotein (LDL and non-HDL) when compared to the classic one. The opposite has been found for adiposity indexes where the classic cut-off seems to present highest performance. Among adiposity indexes, LAP present the highest OR for the relationship with hyperuricemia.

New-onset aortic dilatation in the population: a quarter-century follow-up.

BACKGROUND: Aortic size tends to increase with aging but the extent of this dynamic process has not been evaluated in long-term longitudinal population-based studies. We investigated the incidence of new-onset aortic root (AR) dilatation and its principal correlates among middle-aged adults over a 25-year time period. METHODS: A total of 471 participants with measurable echocardiographic parameters at baseline and after a 25-year follow-up were included in the analysis. Sex-specific upper limits of normality for absolute AR diameter, AR diameter indexed to body surface area (BSA) and to height were derived from healthy normotensive PAMELA participants. RESULTS: New AR dilatation occurred in 7.4% (AR/BSA), 9.1% (AR/height) and 14.6% (absolute AR), respectively. According to the AR/height index, the risk of new dilation was similar in men and women. As for echocardiographic parameters, baseline AR diameter emerged as a key predictor of AR dilation, regardless of the diagnostic criteria and the 10-year change in LVMI was positively associated to new AR/height dilatation. No significant relationship was observed between baseline office and ambulatory systolic/diastolic blood pressure or their changes over time with incident AR dilatation. Baseline and the 25-year change in 24-h pulse pressure were negatively related to new AR dilatation. CONCLUSIONS: The incidence of AR dilatation from mid to late adulthood occurs in a small but clinically relevant fraction of participants and is unaffected by both office and out-office BP. It is significant related to baseline AR diameter and to the 25-year change in LVMI. Our data suggest that echocardiography performed in middle-aged individuals of both sexes may identify those at increased risk of future AR dilatation; moreover, preventing LVH may reduce the risk of progressive AR enlargement.
