Background: The educational differences in the incidence of major cardiovascular events are under-studied in Southern Europe and among women. Methods: The study sample includes n = 5084 participants to 4 population-based Northern Italian cohorts, aged 35–74 at baseline and with no previous cardiovascular events. The follow-up to ascertain the first onset of coronary heart disease (CHD) or ischaemic stroke ended in 2002. At baseline, major cardiovascular risk factors were investigated adopting the standardized MONICA procedures. Two educational classes were obtained from years of schooling. Age- and risk factors-adjusted hazard ratios of first CHD or ischaemic stroke were estimated through sex-specific separate Cox models (high education as reference). Results: Median follow-up time was 12 years. Event rates were 6.38 (CHD) and 2.12 (ischaemic stroke) per 1000 person-years in men; and 1.59 and 0.94 in women. In men, low education was associated with higher mean Body Mass Index and prevalence of diabetes and cigarette smokers; but also with higher HDL cholesterol and a more favourable alcohol intake pattern. Less-educated women had higher mean systolic blood pressure, Body Mass Index and HDL cholesterol and were more likely to have diabetes. Men and women in the low educational class had a 2-fold increase in ischaemic stroke and CHD incidence, respectively, after controlling for major risk factors. Education was not associated with CHD incidence in men. Higher ischaemic stroke rates were observed among more educated women. Conclusion: In this northern Italian population, the association between education and cardiovascular risk seems to vary by gender. [ABSTRACT FROM AUTHOR]

The article examines the rationality of treating white coat hypertension in diabetes. White coat hypertension refers to a condition in which clinic blood pressure repeatedly registers ≥140 millimeters of mercury (mmHg) systolic or 90 mmHg diastolic. The link between white coat hypertension and a risk of cardiovascular disease based on the Pressioni Arteriose Monitorate E Loro Associazioni (PAMELA) population study in Monza, Italy is tackled. The effect of antihypertensive drug treatment on white coat hypertension is discussed.

The article compares the prevalence of metabolic syndrome (MS) in HIV-positive patients with a sample of a general Italian population. The authors determine whether MS and its components have a different frequency in treated and untreated HIV-infected patients. They note that the risk of MS is greater in HIV-infected patients compared with the general population because of a greater prevalence of lipid and glucose abnormalities.

PAMELA (Pressioni Arteriose Monitorate E Loro Associazioni) is an epidemiological study, originally designed to determine the normality of home and ambulatory blood pressure values. The study was performed on 3,200 subjects, aged 25 to 74 years, randomly selected from the general population of Monza (Milan, Italy). In the study context we performed clinical, home and ambulatory blood pressure measurements, echocardiographic assessment of cardiac structure and function as well as laboratory examinations (glucose and lipids). Personal and family histories were collected. The same procedures were repeated 10 years later. During a 12-year follow-up, the incident cardiovascular events were validated. Cardiovascular and all-cause fatal events were collected for a 16-year follow-up. This article will review the main results of the PAMELA study, with particular emphasis on (1) the prognostic value of the different blood pressure measurements, (2) the relationships between metabolic variables and blood pressure and (3) the clinical relevance and prognostic importance of left ventricular mass values and alterations.

Background and Aim: Upper reference values of echocardiographic left-ventricular mass in the European population are based on scanty data mostly derived from northern European population-based samples. Furthermore, data in apparently healthy populations have included individuals with conditions affecting left-ventricular mass such as obesity, diabetes and masked hypertension. Thus, from 1051 individuals with normal office blood pressure (BP) belonging to the PAMELA (Pressioni Arteriose Monitorate E Loro Associazioni) study population, we selected a group of 675 sustained normotensive individuals in order to provide reliable echocardiographic reference values for defining the criteria of left-ventricular hypertrophy (LVH)., Methods: The study group (women 58%, mean age 42 ± 11 years) was identified after excluding individuals with isolated home or ambulatory hypertension, obesity, diabetes, cardiovascular diseases and echocardiographic examinations of insufficient quality to evaluate left-ventricular mass., Results: Sex-specific upper limits of normality [mean + 1.96 standard deviation (SD)] for left-ventricular mass, left-ventricular mass indexed to body surface area, heightand height were the following: 213 g, 114 g/m, 51 g/h, 123 g/h in men and 161 g, 99  g/m, 47 g/h, 101 g/h in women. In multivariate analyses, body size measures and ambulatory BP levels were the most important correlates of left-ventricular mass., Conclusions: Our investigation by providing upper reference limits of left-ventricular mass in a southern European population sample, carefully selected after exclusion of a large number of conditions affecting left-ventricular mass, may offer a contribution for revising diagnostic criteria of echocardiographic LVH currently recommended by European hypertension guidelines.

Obesity is associated with a higher risk of developing diabetes mellitus (DM), hypertension (HT), and left ventricular hypertrophy (LVH). The present study assessed in the general population the impact of body weight and visceral obesity on the development of alterations in glucose metabolism and cardiac structure, as well as of elevation in blood pressure. In 1412 subjects randomly selected and representative of the general population of Monza, we assessed twice (in 1990/1991 and 2000/2001) body mass index (BMI); waist circumference; office, home, and 24-hour ambulatory (24-hour) blood pressure, fasting glycemia, and left ventricular mass (echocardiography). New-onset high-risk conditions were DM; impaired fasting glucose; office, home, and 24-hour HT; and LVH. The incidence of new-onset DM; impaired fasting glucose; office, home, and 24-hour HT; and LVH increased progressively from the quintile with the lowest to the quintile with the highest BMI values. Adjusting for confounders, the risk of developing new-onset DM; impaired fasting glucose; office, home, and 24-hour HT; and LVH increased significantly for an increase of 1 kg/m(2) of BMI and 1 cm of waist circumference (respectively, 8.4% [P<0.01], 9.5% [P<0.0001], 4.2% [P<0.0001], 3.9% [P<0.001], 2.5% [P<0.05], and 5.1% [P<0.001] for BMI and 3.2% [P<0.001], 3.5% [P<0.0001], 1.8% [P<0.0001], 1.5% [P<0.0001], 1.4% [P<0.001], and 2.6% [P<0.0001]). These data provide evidence that an increase in BMI and waist circumference is associated with a linearly increased adjusted risk of developing conditions with high cardiovascular risk, such as DM, impaired fasting glucose, in- and out-of-office HT, and LVH.

Objectives: We investigated the contribution of major coronary heart disease (CHD) risk factors and job strain to occupational class differences in CHD incidence in a pooled-cohort prospective study in northern Italy., Methods: 2964 men aged 25-74 from four northern Italian population-based cohorts were investigated at baseline and followed for first fatal or non-fatal CHD event (171 events). Standardised procedures were used for baseline risk factor measurements, follow-up and validation of CHD events. Four occupational classes were derived from the Erikson-Goldthorpe-Portocarero social class scheme: higher and lower professionals and administrators, non-manual workers, skilled and unskilled manual workers, and the self-employed. HRs were estimated with Cox models., Results: Among CHD-free subjects, with non-manual workers as the reference group, age-adjusted excess risks were found for professionals and administrators (+84%, p=0.02), the self-employed (+72%, p=0.04) and manual workers (+63%, p=0.04). The relationship was consistent across different CHD diagnostic categories. Adjusting for major risk factors only slightly reduced the reported excess risks. In a sub-sample of currently employed subjects, adjusting for major risk factors, sport physical activity and job strain reduced the excess risk for manual workers (relative change = -71.4%) but did not substantially modify the excess risks of professionals and administrators and the self-employed., Conclusions: In our study, we found higher CHD incidence rates for manual workers, professionals and administrators, and the self-employed, compared to non-manual workers. When the entire spectrum of job categories is considered, the job strain model helped explain the CHD excess risk for manual workers but not for other occupational classes.

Objective: To see whether there is interaction between single nucleotide polymorphisms (SNPs) belonging to candidate genes for hypertension and job strain and its components (job demand and job control) in an accurately phenotyped Italian cohort (Pressioni Arteriose Monitorate E Loro Associazioni)., Methods: From the Pressioni Arteriose Monitorate E Loro Associazioni cohort, we sampled 924 employed men and women who had completed a modified version of the Karasek questionnaire and for whom deoxyribonucleic acid information was available. We selected 1,510 common tagging and putative functional SNPs in 92 candidate autosomal genes involved in sympathetic nervous system, oxidative stress, renin-angiotensin-aldosterone system, and sodium balance. The interaction of each candidate SNP with the perceived job stress scores on ambulatory systolic and diastolic blood pressures was evaluated by adding product terms to a multiple regression linear model, adjusted for sex, age, total cholesterol, and body mass index., Results: Among all the SNPs tested, the interaction of SNP rs11210278 located on the endothelin 2 gene and job control was statistically significant after controlling for multiple testing, using false discovery rate (unadjusted p = .00000661; p adjusted for false discovery rate = .0085), indicating an inverse association with systolic blood pressure for the homozygous wild-type allele (C/C) and a positive association for the variant genotypes (C/T and T/T)., Conclusions: We show that the hypertensive response to job strain is present only in carriers of the rs11210278 wild-type genotype. The phenomenon is discussed in relationship to the controversial results of field studies on job strain and hypertension.

Objectives: Previous studies have shown that left ventricular hypertrophy (LVH) represents a cardiovascular risk factor independently of clinic blood pressure (BP). The present study was aimed at determining the impact of LVH on the incidence of cardiovascular morbid and fatal events taking into account not only classical risk factors but also home and ambulatory BP values, which have been shown to have an important independent prognostic impact., Methods: In 1716 patients belonging to the 'Pressioni Arteriose Monitorate E Loro Associazioni' population of Monza, we quantified left ventricular mass index and identified LVH by standard cutoff values. We also measured clinic, home and 24-h ambulatory BPs together with serum glucose and lipids., Results: During a follow-up of 148 months, the rate of fatal and nonfatal (hospitalizations) cardiovascular events as well as of all-cause death was markedly greater (four-fold to five-fold) in patients as compared with those without LVH. In LVH individuals, the increased risk remained significant even when data were adjusted for a large number of other confounding factors including home BP, 24-h mean BP and ambulatory BP. Results were similar when left ventricular mass was indexed by height and body surface area. A 10% increase in left ventricular mass index was associated with a significant increase in cardiovascular risk or all-cause deaths. In multivariate analysis, left ventricular mass index was always an independent predictor of cardiovascular events and death for any cause., Conclusion: Our data provide evidence that LVH is an important risk factor even when the contribution of different BPs to risk is fully taken into account.

The hypothesis has been advanced that cardiovascular prognosis is related not only to 24-hour mean blood pressure but also to blood pressure variability. Data, however, are inconsistent, and no long-term prognostic study is available. In 2012 individuals randomly selected from the population of Monza (Milan), 24-hour ambulatory blood pressure (Spacelabs 90207) was measured via readings spaced by 20 minutes. Systolic and diastolic blood pressure variability was obtained by calculating the following: (1) the SD of 24-hour, day, and night mean values; (2) the day-night blood pressure difference; and (3) the residual or erratic blood pressure variability (Fourier spectral analysis). Fatal cardiovascular and noncardiovascular events were registered for 148 months. When adjusted for age, sex, 24-hour mean blood pressure, and other risk factors, there was no relationship between the risk of death and 24-hour, day, and night blood pressure SDs. In contrast, the adjusted risk of cardiovascular death was inversely related to day-night diastolic BP difference (beta coefficient=-0.040; P<0.02) and showed a significant positive relationship with residual diastolic blood pressure variability (beta coefficient=0.175; P<0.002). Twenty-four-hour mean blood pressure attenuation of nocturnal hypotension and erratic diastolic blood pressure variability all independently predicted the mortality risk, with the erratic variability being the most important factor. Our data show that the relationship of blood pressure to prognosis is complex and that phenomena other than 24-hour mean values are involved. They also provide the first evidence that short-term erratic components of blood pressure variability play a prognostic role, with their increase being accompanied by an increased cardiovascular risk.

Background: Cardiovascular risk factor research has recently broadened its focus based on new data indicating the benefits of low risk, i.e. favorable levels of all major risk factors. The aims of this study were to assess further the relation of low risk to coronary heart disease risk, and implications for prevention., Design: We conducted a prospective population-based Italian study, of 7438 men and 13 009 women aged 35-69 years, with a mean follow-up of 10.4 years and validated first coronary events., Methods: Baseline coronary heart disease risk was classified into three categories: low risk; unfavorable but not high risk; and high risk. To analyze the relation of these risk profiles to coronary heart disease incidence, age-adjusted, sex-averaged coronary heart disease incidence was calculated for persons free of coronary heart disease and stroke, stratified as baseline low risk, unfavorable but not high risk or high risk. To assess the independent relationship of individual risk factors to coronary heart disease incidence, multivariate proportional hazards models were computed for combinations of risk factors., Results: Only 2.7% of participants met low risk criteria; 81.4% were high risk. Age-adjusted coronary heart disease incidence for the whole cohort was 37.1 out of 10000 person-years (men 59.0; women 15.3). No coronary heart disease events occurred in low-risk men, only two in low-risk women. For women and men who were not high risk, the age-sex standardized coronary heart disease rate was 62% lower than for high-risk participants. Blood pressure, need for antihypertensive medication, smoking, hyperglycemia, diabetes, total and high-density lipoprotein cholesterol were independently related to coronary heart disease risk., Conclusions: Favorable levels of all modifiable readily measured risk factors - rare among Italian adults - assure minimal coronary heart disease risk. Population-wide prevention is needed, especially improved lifestyles, to increase the proportion of the population at low risk.

Recently, the focus of research on cardiovascular risk factors has broadened because of new data demonstrating benefits of low risk (i.e., favorable) levels of all major modifiable risk factors. Most data on low risk relate to coronary heart disease, not stroke. This population-based, 12-sample, Italian study (Progetto CUORE, 1983-2002), with 10-year follow-up, assessed the relation of low risk to stroke and implications for prevention. At baseline, women and men were 35-69 years of age. Only 3% were low risk; 80% were high risk. Overall, stroke incidence rates were 20.7 for men and 9.6 for women per 10,000 person-years. No strokes occurred in low risk participants, and stroke incidence was low with borderline elevation of only one risk factor. Four modifiable risk factors--elevated blood pressure, smoking, diabetes, and high total cholesterol/high density lipoprotein cholesterol ratio--related independently to stroke risk. For those at low risk or who had only one unfavorable (but not high) risk factor, the stroke rate was 76% lower than for high risk participants; for all persons not at high risk, the stroke rate was 57% lower than for those at high risk. Results show that favorable risk factor levels assure minimal stroke risk. Population-wide prevention is needed, especially improved lifestyles, to increase the prevalence of low risk.

Background: Menopause is commonly associated with some blood pressure (BP) rise, but cross-sectional or longitudinal studies completed so far were often too small and were unable to indicate whether this BP increase is really dependent on menopause, or was caused by age or changes in body mass index (BMI)., Methods and Results: The SIMONA study (Study on Hypertension Prevalence in Menopause in the Italian population) was a large cross-sectional study on 18 326 women of age range 46-59 years, consecutively seen by 302 practitioners all over Italy, and representing 60% of the women of that age in the National Health care list of those doctors. BP was measured three times in the seated position by the same automatic machine, and demographic and clinical data were taken. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were slightly but significantly higher in postmenopausal than premenopausal and perimenopausal women, but so were age and BMI. Within seven biannual strata, differences in age and BMI were minimized, but SBP/DBP remained significantly higher (by 3.4/3.1 mmHg) in postmenopausal than in premenopausal subjects in the youngest stratum (46-47 years), and was also significantly higher in the stratum 48-49 years. The differences remained significant after the exclusion of 1809 women with surgical menopause or 695 women with cardiovascular disease. Even when the confounding effects of age, BMI, smoking and contraceptive or replacement therapies were excluded by analysis of covariance, menopause was significantly and positively associated with SBP and DBP (approximately 2 mmHg difference in the age range 46-49 years)., Conclusion: Menopause is associated with a slightly but significantly higher BP, even after adjustment for age and BMI, as well as other confounding factors, but the association is evident only in the younger end of the age range related to menopause.

Background: Studies in hypertensive patients suggest that ambulatory blood pressure (BP) is prognostically superior to office BP. Much less information is available in the general population, however. Obtaining this information was the purpose of the Pressioni Arteriose Monitorate e Loro Associazioni (PAMELA) study., Methods and Results: Office, home, and 24-hour ambulatory BP values were obtained in 2051 subjects between 25 and 74 years of age who were representative of the general population of Monza (Milan, Italy). Subjects were followed up for an average of 131 months, during which time cardiovascular and noncardiovascular fatal events were recorded (n=186). Office, home, and ambulatory BP values showed a significant exponential direct relationship with risk of cardiovascular or all-cause death. The goodness of fit of the relationship was greater for systolic than for diastolic BP and for night than for day BP, but its overall value was not better for home or ambulatory than for office BP. The slope of the relationship, however, was progressively greater from office to home and ambulatory BP. Home and night BP modestly improved the goodness of fit of the risk model when added to office BP., Conclusions: In the PAMELA population, risk of death increased more with a given increase in home or ambulatory than in office BP. The overall ability to predict death, however, was not greater for home and ambulatory than for office BP, although it was somewhat increased by the combination of office and outside-of-office values. Systolic BP was almost invariably superior to diastolic BP, and night BP was superior to day BP.

Background: The aims of this paper are to derive a 10-year coronary risk predictive equation for adult Italian men, and to assess its accuracy in comparison with the Framingham Heart Study (FHS) and PROCAM study equations., Methods: The CUORE study is a prospective fixed-cohort study. Eleven cohorts, from the north and the centre-south of Italy, had been investigated at baseline between 1982 and 1996, adopting MONICA methods to measure risk factors. Among this sample of 6865 men, aged 35-69 years and free of coronary heart disease (CHD) at baseline, 312 first fatal and non-fatal major coronary events occurred in 9.1 years median follow-up. Calibration, as the difference between 10-year predicted and actual risk, and discrimination, as the ability of the risk functions to separate high-risk from low-risk subjects, have been assessed to compare accuracy of the FHS, the PROCAM, and the CUORE study equations., Results: The best CUORE equation includes age, total cholesterol, systolic blood pressure, cigarette smoking, HDL-cholesterol, diabetes mellitus, hypertension drug treatment, and family history of CHD (area under the ROC curve = 0.75). The uncalibrated estimates of the 10-year risk in this CUORE follow-up data were 0.093 and 0.109 higher (P < 0.05) from the Framingham and PROCAM risk scores, respectively, than the Kaplan-Meier estimate for CUORE, indicating risk overestimates for both equations. Standard recalibration techniques improved accuracy of the FHS equation only. PROCAM overestimates were prominent in the higher risk deciles. With an alternative method for recalibration better risk estimates were obtained, but a cohort study was needed to obtain a properly calibrated risk equation., Conclusions: The CUORE Project predictive equation showed better accuracy of the FHS and PROCAM equations, overcoming frequently reported risk overestimates. The CUORE equation may be adopted to identify men with high coronary risk in Italy.

Background: Risk charts, built through risk functions deriving from longitudinal studies, are used in order to identify individuals at high risk for cardiovascular disease. For this reason the function has been identified and the global cardiovascular risk chart of the CUORE Project has been prepared, using Italian data coming from different cohorts enrolled between the '80s and the '90s, whose risk factors had been collected by standardized procedures., Methods: The following risk factors have been used: age (10-year period, 40-49, 50-59, 60-69 years), gender (men and women), systolic blood pressure (< or = 129, 130-149, 150-169, > or = 170 mmHg), serum cholesterol (< or = 173, 174-212, 213-251, 252-290, > or = 291 mg/dl), smoking habit (yes, no) and presence of diabetes (yes, no); the first coronary or cerebrovascular event in people aged 40-69 years with no other previous cardiovascular events was considered as endpoint; survival has been assessed up to December 1998., Results: Out of 18,028 people aged 40-69 years with no previous cardiovascular events, 647 first major cardiovascular events have been identified and validated, 449 coronary and 198 cerebrovascular. Charts are divided according to men and women and to diabetics and non-diabetics respectively; the different colors represent the percent level of risk and go from light green (< 5% in 10 years for men, < 1% in 5 years for women), dark green (between 5 and 10% for men, between 1 and 3% for women), yellow (between 10 and 15% for men, between 3 and 5% for women), orange (between 15 and 20% for men, between 5 and 7% for women), red (between 20 and 30% for men, between 7 and 10% for women), violet (> 30% for men, > 10% for women)., Conclusions: The risk charts were built with data collected in recent years on men and women with a median follow-up of 10 years for men and 5 years for women, considering the first major fatal or non-fatal cardiovascular event as endpoint. Such a tool is easy to be applied by general practitioners and cardiologists in order to achieve a fast and objective evaluation of global cardiovascular risk.

To identify individuals at high risk for cardiovascular disease, the function of the Progetto CUORE has been identified and the global cardiovascular risk score has been built using data from different cohorts enrolled in the North, Center and South of Italy between the 80s and the 90s, whose risk factors had been collected using standardised procedures. A follow-up with a median duration of 9.5 years for men and 8.0 years for women has been achieved. Age, systolic blood pressure, total cholesterol, HDL-cholesterol, smoking habit, diabetes and hypertension treatment have been included in the function; the first major coronary or cerebrovascular event was considered as endpoint; 10-year survival has been assessed both for men and women. Out of 20 647 people aged 35-69 years with no previous cardiovascular events, 971 major cardiovascular events (636 coronary and 335 cerebrovascular) have been identified and validated. Risk factors coefficients have been assessed using the Cox proportional hazard model separately for men and women. The individual score is easy to be applied by general practitioners and cardiologists in order to achieve a fast and objective evaluation of the absolute global cardiovascular risk in primary prevention.

Background: Previously reported time trends of myocardial infarction rates in the MONICA Brianza 35-64-year-old population showed a clear decline in coronary heart disease mortality, mostly attributable to concurrent reductions in myocardial infarction attack rates, and to a lesser extent in 28-day case fatality. The aims of this study were to estimate time trends in more recent years (up to 1997-1998) in the same population and in the same age range, and to assess the impact of myocardial infarction among 35-74-year-old residents, an age range never investigated before in Italy using standardized population-based registers., Methods: The myocardial infarction register in the Brianza population was resumed in 1997-1998, adopting the same standardized methods for data collection and classification of suspect coronary events as the WHO MONICA project, including the age group 65-74 years in addition to age groups usually covered. Age-specific and age-standardized rates of validated coronary mortality rates, of attack rates, and incidence rates and of 28-day case fatality were calculated. Time changes were estimated as the difference in rates., Results: In comparison to the rates among 35-64-year-old residents, the 35-74 age-standardized rates of coronary event mortality in the biennium are more than 3 times higher in women and more than twice in men. Similarly, the attack and incidence rates increased respectively from 243 to 381 and from 197 to 292 per 100,000 in men, from 38 to 107 and from 33 to 87 per 100,000 in women. Statistically significant reductions are observed in coronary death rates, myocardial infarction attack rates and 28-day case-fatality rates between 1993-1994 and 1997-1998 in men. Analogous but not statistically significant changes are reported for women., Conclusions: In the Brianza MONICA population in the second half of the 1990s, coronary event death rates continued to decrease. In contrast with trends observed in previous years, the prominent quote of the reduction is attributable to case-fatality rates in the acute phase.

Objective: The extent to which psychosocial stress concurs to raise blood pressure is still uncertain. Here the association between job strain and office blood pressure in a pooled analysis of four population samples from northern Italy is assessed., Methods: Four surveys assessing prevalence of major coronary risk factors were performed in 1986, 1990, 1991, and 1993 in area "Brianza" (Milan), a World Health Organization-MONItoring cardiovascular disease (WHO-MONICA) Project collaborating center. Ten year age- and gender-stratified independent samples were randomly recruited from the 25- to 64-year-old residents. The methods used to assess coronary risk factors strictly adhered to the MONICA manual, were kept constant, and underwent internal and external quality controls. Job strain was investigated through the administration to employed participants of a questionnaire derived from the Karasek model, assessing job demand/control latitude. Analysis was restricted to 25- to 54-year-old participants, untreated for hypertension (1799 men and 1010 women)., Results: Among men, there was a 3 mm Hg increase of systolic blood pressure (p<.001) moving from low to high strain job categories. This difference was independent from age, education, body mass index, alcohol intake, smoking habits, leisure time physical activity, and survey. No relevant differences among job strain categories were found in women and for diastolic blood pressure in both gender groups., Conclusions: These results carried out on a large population-based sample confirm previous findings obtained adopting ambulatory blood pressure measurements in more restricted samples of population or patients. Further research is needed to clarify the relationship between perceived work stress and blood pressure in women.

Previous studies have shown that in the population, only a minority of treated hypertensive patients achieve blood pressure (BP) control. Whether and to what extent this inadequate control has reflection on hypertension-related organ damage has never been systematically examined. In 2051 subjects belonging to the PAMELA (Pressioni Arteriose Monitorate E Loro Associazioni) Study population, we measured office, home, and 24-hour ambulatory BP values, together with echocardiographic left ventricular mass and wall thickness. Based on the fraction on antihypertensive treatment and on measurements of increased or normal office, home, or 24-hour ambulatory BP values, subjects were classified as normotensives, untreated hypertensives, treated hypertensives with inadequate BP control, and treated hypertensives with effective BP control. Compared with values in the normotensive group, left ventricular mass index, left ventricular wall thickness, and prevalence of left ventricular hypertrophy were markedly increased not only in untreated hypertensive patients but also in treated hypertensives with inadequate BP control. Echocardiographic abnormalities were less in treated hypertensives with BP control than in patients with inadequate BP control, but values were still clearly greater than in normotensive subjects. This was the case regardless whether BP control was assessed by office, home, and/or ambulatory values. Our data provide evidence that in the hypertensive fraction of the population, cardiac structural alterations can be frequently found in both the presence and absence of antihypertensive treatment. They also imply that even effective treatment of hypertension does not allow complete reversal of the cardiac organ damage characterizing high BP states.
