Prevalence and control of hypertension in the general practice in Italy: updated analysis of a large database.

Systematic assessment of blood pressure (BP) control rates may help to improve the clinical management of hypertension in clinical practice. This approach had limited application in Europe over the last three decades and only recently has been implemented in some countries. The present study is aimed at evaluating hypertension prevalence and control among adult outpatients followed by a large, representative sample of general practitioners (GPs) in Italy. We retrospectively analysed the data derived from the GP Health Search-CSD database in 2013. Hypertension prevalence and control were estimated within the overall population sample and in hypertensive outpatients, respectively, according to age and gender. Hypertension diagnosis was defined according to the International Classification of Diseases 9. Clinic BP levels were measured according to the European guidelines. BP control was defined as systolic/diastolic BP <140/90 mm Hg. Data from 911 753 individuals (52.2% females) were scrutinized. Hypertension was diagnosed in 236 377 (25.9%) patients, being higher in male aged <70 years than age-matched female. Hypertension control was recorded in 60.6% of hypertensive patients, being higher in female than male individuals aged <70 years. Our current analysis demonstrates that about 26% of adult outpatients followed in the GP setting had hypertension and that about 61% had controlled BP levels. Both prevalence and control of hypertension appear to be higher when compared with the data reported from the analysis of the same database in 2005, thus confirming a positive trend in BP control in the GP clinical setting in Italy.

Clinical management of patients with hypertension and high cardiovascular risk in specialised centers and in general practice. Analysis from an Italian Survey Questionnaire.

BACKGROUND AND AIM: Hypertension control remains poorly achieved worldwide, despite the use of modern diagnostic tools and advanced therapeutic strategies. We aimed to evaluate the preferences expressed by either specialised physicians (SPs) or general practitioners (GPs) for the clinical management of hypertension and high cardiovascular risk in Italy. METHODS AND RESULTS: A predefined questionnaire was anonymously administered to a large community sample of physicians, stratified according to clinical expertise. From a total of 64 questions, 557 physicians (478 male, mean age 54.2 ± 7.1 years, average age of medical activity 28.0 ± 8.1 years), including 261 (46.9%) SPs and 296 (53.1%) GPs, provided 9564 answers to the survey questionnaire. Involved clinicians spent the majority of their time and practice for hypertension management and control. SPs aimed to achieve the recommended BP targets (<140/90 mmHg), whereas GPs tended to achieve more rigorous BP goals (<130/80 mmHg); nonetheless, they both reported a very high rate of BP control (about 70%). Concomitant presence of diabetes, organ damage, as well as comorbidities, was reported to be relatively frequent (26-50%), mostly by SPs. ESH/ESC 2007 risk score stratification was preferred by SPs compared to GPs, who favored a comprehensive clinical evaluation. ACE inhibitors or ARBs were considered the best pharmacological option to start antihypertensive treatment, thus adding diuretics or calcium-channel blockers, if needed. CONCLUSIONS: This predefined analysis of a survey questionnaire showed relatively different opinions with respect to recommended BP targets and distributions of cardiovascular risk profile, and similar diagnostic and therapeutic choices between GPs and SPs.

Blood pressure levels and control in Italy: comprehensive analysis of clinical data from 2000-2005 and 2005-2011 hypertension surveys.

This analysis is aimed to determine blood pressure (BP) levels and BP control rates in a large population of hypertensive patients in Italy. Data were taken from two large and inclusive cross-sectional surveys, which covered two distinct and subsequent time periods (2000-2005 and 2005-2011, respectively). Observational clinical studies and surveys, which reported average systolic/diastolic clinic BP levels, proportions of treated/untreated and controlled/uncontrolled patients, and prevalence of cardiovascular risk factors in hypertensive patients followed in either outpatient clinics, hypertension centres or general practice, were considered for the analyses. The overall sample included 211 591 hypertensive patients (119 997 (56.7%) women, age 57.0±10.0 years, body mass index 26.9±4.0 kg m(-2), BP levels 146.9±16.7/88.7±9.6 mm Hg). BP levels were 148.2±15.4/87.5±9.3 mm Hg in patients followed by general practitioners (n=168 313, 79.5%), 148.1±17.3/90.1±9.7 mm Hg in those followed by hypertension centres (n=28 180, 13.3%), and 142.4±17.6/86.6±9.8 mm Hg in those followed by outpatient clinics and hospital divisions (n=15 098, 7.1%). Among treated hypertensive patients (n=128 079; 60.5%), 43 008 (33.6%) were reported to have controlled BP levels. Over one decade of observation, we reported that ~60% of hypertensive patients were treated and among these only 33% achieved effective BP control. These findings highlight the need for more effective interventions to improve management of hypertension in Italy.

Attitudes and preferences for the clinical management of hypertension and hypertension-related cardiac disease in general practice: results of the Italian Hypertension and Heart Survey.

The aim of this study was to evaluate attitudes and preferences for the clinical management of hypertensive patients with cardiac organ disease, including left ventricular hypertrophy (LVH) and coronary artery disease (CAD), in Italy. A predefined 15-item questionnaire was anonymously administered to a large community sample of general practitioners (GPs) and specialised physicians between November 2012 and June 2013. Estimated prevalence of hypertension-related clinical conditions was stratified into four groups (10-20%, 20-40%, 40-50%, >50%); preferences were reported as percentage among valid answers to the survey questionnaire. A total of 1319 physicians (672 males, age 55.0 ± 7.1 years, age of medical activity 27.1 ± 7.6 years), among whom 1264 GPs and 55 specialised physicians, was included. LVH was reported to be the most frequent marker of organ damage by the majority of physicians (73.5%). LV diastolic dysfunction was reported to be relatively frequent (>40%) by more than half of the specialised physicians (58.2%) and less frequent (10-20%) by GPs (49.8%); LV systolic dysfunction, atrial fibrillation and CAD were considered to be less frequent (10-20%) by the majority of physicians (61.3, 71.6 and 53.3%, respectively). Echocardiography was the preferred diagnostic tool used to estimate LVH (76.6%). Tight blood pressure control (130/80 mm Hg) was considered to be the most appropriate by the majority of physicians, both in hypertensive patients with LVH and in those with CAD. With the well-known limitations of a cross-sectional survey, this study provides information on attitudes and preferences for the clinical management of outpatients with hypertension and high CV risk profile in general practice in Italy.

Four proteins governing overangiogenic endothelial cell phenotype in patients with multiple myeloma are plausible therapeutic targets.

Bone marrow (BM) angiogenesis has an important role in the initiation and progression of multiple myeloma (MM). We looked at novel mechanisms of vessel formation in patients with MM through a comparative proteomic analysis between BM endothelial cells (ECs) of patients with active MM (MMECs) and ECs of patients with monoclonal gammopathy of undetermined significance (MGECs) and of subjects with benign anemia (normal ECs). Four proteins were found overexpressed in MMECs: filamin A, vimentin, α-crystallin B and 14-3-3ζ/δ protein, not yet linked to overangiogenic phenotype. These proteins gave a typical distribution in the BM of MM patients and in MMECs versus MGECs, plausibly according to a different functional state. Their expression was enhanced by vascular endothelial growth factor, fibroblast growth factor 2, hepatocyte growth factor and MM plasma cell conditioned medium in step with enhancement of MMEC angiogenesis. Their silencing RNA knockdown affected critical MMEC angiogenesis-related functions, such as spreading, migration and tubular morphogenesis. A gradual stabilization of 14-3-3ζ/δ protein was observed, with transition from normal ECs to MGECs and MMECs that may be a critical step for the angiogenic switch in MMECs and maintenance of the cell overangiogenic phenotype. These proteins were substantially impacted by anti-MM drugs, such as bortezomib, lenalidomide and panobinostat. Results suggest that these four proteins could be new targets for the antiangiogenic management of MM patients.

Global cardiovascular risk management in different Italian regions: an analysis of the Evaluation of Final Feasible Effect of Control Training and Ultra Sensitisation (EFFECTUS) educational program.

BACKGROUND AND AIM: The Final Evaluation Feasible Effect of Ultra Control Training and Sensitization (EFFECTUS) is an educational program, aimed at improving global CV risk stratification and management in Italy. The present study evaluates differences on clinical approach to global CV risk among physicians involved in the EFFECTUS program and stratified in three geographical macro-areas (North, Center, South) of our Country. METHODS AND RESULTS: Physicians were asked to submit data already available in their medical records, covering the first 10 adult outpatients, consecutively seen in the month of May 2006. Overall, 1.078 physicians (27% females, aged 50 ± 7 years) collected data of 9.904 outpatients (46.5% females, aged 67 ± 9 years), among which 3.219 (32.5%) were residents in Northern, 3.652 (36.9%) in Central and 3.033 (30.6%) in Southern Italy. A significantly higher prevalence of major CV risk factors, including obesity, physical inactivity, hypertension and diabetes, was recorded in Southern than in other areas. Accordingly, Southern physicians more frequently prescribed antihypertensive, glucose and lipid lowering agents than other physicians, who paid significantly more attention to life-style changes in their clinical practice. CONCLUSIONS: This analysis of the EFFECTUS study demonstrates a high prevalence of CV risk factors in Italy, particularly in Southern areas, and indicates some important discrepancies in the clinical management of global CV risk among physcians working in different Italian regions.

Impact of physicians' age on the clinical management of global cardiovascular risk: analysis of the results of the Evaluation of Final Feasible Effect of Control Training and Ultra Sensitisation Educational Programme.

AIM: To evaluate the potential impact of physicians' age on global cardiovascular (CV) risk management in the population of the Evaluation of Final Feasible Effect of Ultra Control Training and Sensitisation (EFFECTUS) study. METHODS: Involved physicians were stratified into three age groups (≤ 45, 46-55 and > 55 years), and asked to provide clinical data covering the first 10 adult outpatients, consecutively seen in May 2006. RESULTS: Overall 1078 physicians, among whom 219 (20%) were aged ≤ 45, 658 (61%) between 46 and 55, and 201 (19%) > 55 years, collected data of 9904 outpatients (46.5% female patients, aged 67 ± 9 years), who were distributed into three corresponding groups: 2010 (20%), 6111 (62%) and 1783 (18%), respectively. A higher prevalence of myocardial infarction and stroke was recorded by younger physicians rather than those aged > 46 years. Older physicians frequently recommended life-style changes, whereas a higher number of antihypertensive, antiplatelet, glucose and lipid-lowering prescriptions was prescribed by physicians aged ≤ 45 years. CONCLUSIONS: This analysis of the EFFECTUS study indicates a higher prevalence of vascular diseases among outpatients who were followed by younger physicians, who prescribed a higher number of CV drugs than older physicians. These older physicians have more attitude for prescribing favourable life-style changes than younger physicians.

Management of hypertension and stroke prevention: results of the Italian cardiologist survey.

OBJECTIVE: To provide an overview of current habits, priorities, perceptions and knowledge of cardiologists with regard to hypertension and stroke prevention in outpatient practice. METHODS: A sample of 203 cardiologists operating in outpatient clinics and randomly selected amongst members of the largest Italian Outpatient Cardiologist Association were interviewed by e-mail, in April-May 2007. RESULTS: The interviewed cardiologists reported that hypertensive outpatients represent a large percentage of their practice population, in which the clinical priority was blood pressure (BP) reduction. Stroke was identified as the most important event to prevent and it was also perceived as the most preventable hypertension-related cardiovascular event. A remarkably high rate of achieved BP control was reported, to a degree that it is inconsistent with current epidemiological reports and with the relatively low percentage use of combination therapies declared by cardiologists. Additional risk factors, organ damage, diabetes mellitus and atrial fibrillation were consistently reported in hypertensive patients. Among antihypertensive drug classes, a preference for angiotensin-converting enzyme inhibitors has been expressed by the majority of physicians; this choice was generally justified by evidence derived from international trials or by the antihypertensive efficacy of this drug class. CONCLUSIONS: The results confirm the presence of weaknesses in the current services for patients with hypertension, even when being managed by cardiologists. Discrepancies between perceptions and reality, or clinical practice and guideline recommendations are also highlighted. An analysis of these aspects may help to identify current areas of potential improvement for stroke prevention in the clinical management of hypertension in cardiology practice.

Mortality of plastic-ware workers exposed to radiofrequencies.

The mortality experience of a cohort of Italian plastic-ware workers exposed to radiofrequency (RF)-electromagnetic fields generated by dielectric heat sealers was investigated. Follow-up extended from 1962 to 1992. The standardised mortality ratio (SMR) analysis was restricted to 481 women workers, representing 78% of the total person-years at risk. Mortality from malignant neoplasms was slightly elevated, and increased risks of leukemia and accidents were detected. The all-cancer SMR was higher among women employed in the sealing department, where exposure to RF occurred, than in the whole cohort. This study raises interest in a possible association between exposure to RF radiation and cancer risk. However, the study power was very small, and the possible confounding effects of exposure to solvents and vinyl chloride monomer (VCM) could not be ruled out. The hypothesis of an increased risk of cancer after radiofrequency exposure should be further explored by means of analytical studies characterised by adequate power and more accurate exposure assessment.

[Modification of the sympatho-vagal interaction in mitral valve prolapse syndrome. Evaluation of heart rate variability by spectrum analysis]. / Modificazioni del tono neurovegetativo nella sindrome del prolasso valvolare mitralico. Studio della variabilità della frequenza cardiaca mediante analisi spettrale.

To determine whether clinical manifestations in patients with mitral valve prolapse (MVP) are associated with altered sympatho-vagal tone, 46 patients (mean age 27 +/- 6, range 20-45 years; 18 males and 28 females) were studied by power spectrum analysis of RR variability. Patients were divided in 2 groups, according to echocardiographic criteria: Group A: 11 patients with classical MVP; Group B: 35 patients with non classical MVP. These patients were compared with 30 healthy subjects (Group C) well matched for age, body surface area and heart rate. Our findings indicate that at rest there is a significant difference in the high-frequency component between Group A and Group C. Similarly, during the increase in sympathetic activity induced by 70 degrees head-up tilt all groups showed an increase in the low-frequency component, that was more evident in Group A. The data generated from our laboratory suggest that mitral regurgitation (Group A) is a probable cause of vagal tone increase and that there is an adaptive long-term mechanism towards sympathetic conditions. In addition, probably the normalization, demonstrable by the effect of sympathetic activity in tilt, can mask a dysfunction that may be differently evoked.

Nocturnal headache-hypertension syndrome: a chronobiologic disorder.

The study of blood pressure (BP) monitoring in essential hypertensive patients recurrently suffering from nocturnal headache revealed a rhythmic elevation of sphygmomanometric values during the night. Such a finding was not detected in essential hypertensive patients suffering from occasional headache. The nocturnal elevation of BP was seen to be paralleled by the circadian peak of heart rate, suggesting that the disorder is a systemic phenomenon. Importantly, the headache episodes were seen to disappear after antihypertensive therapy that was adjusted to lower the nocturnal increase of BP. The therapeutic results suggested that the nocturnal headache was dependent on the phasic elevation of BP. The beneficial effects further suggested that the nocturnal headache and the nocturnal elevation of BP may represent a particular syndrome with a cause-effect relationship. The term "nocturnal headache-hypertension syndrome" is proposed.

Lack of adverse cardiac effects of combined treatment with theophylline and albuterol in asthmatic children.

Our study was designed to assess potential cardiovascular adverse effects in clinically stable asthmatic children due either to oral sustained-release theophylline or theophylline in combination with an inhaled beta-2 adrenergic agonist. Twenty-five asthmatic children were evaluated while receiving no drugs, theophylline alone, and theophylline with an inhaled beta-2 adrenergic agonist. In each phase all patients underwent 24- to 48-hour Holter monitoring and a maximal treadmill exercise test. The results show that neither theophylline alone nor combined therapy was associated with any relevant cardiovascular adverse effect, including ectopic cardiac activity. A nonsignificant increase in mean heart rate was observed between each period of study. The data suggest that the use of theophylline either alone or in combination with a beta-2 adrenergic agonist in clinically stable asthmatic children is not associated with any serious cardiovascular effect.

Pressor effects from daily events and laboratory complex stimuli relating personality factors.

Our preliminary research has attempted to establish a series of methods to study the complex interactions occurring between pressor reactivity and personality profile. Ten untreated mild hypertensives (age 42.9 +/- 8) without damaged target organs were recruited from an outpatient hypertension center along with an equal number of normotensive volunteers (age 38.2 +/- 8.1). We performed a sequence of stressor types under laboratory conditions (sensory perceptual activities, psychomotor responses, and cognitive behavior) following an order ranging from inferior levels to superior levels of systemic integration. The subjects also underwent a 24-h automatic noninvasive blood pressure recording which took into account the situational reactivity. They filled in MMPI and STAI questionnaires before and after the stressor batteries. Only the sensory-perceptual test (Stroop color test modified), the arithmetic test, and the psychomotor test provoked a significant increase in blood pressure and, in the latter test, also a significant increase of the heart rate. The test batteries' mean differences were not significant between the two groups. Similarly, the answers to the trait-anxiety questionnaires did not allow us to make a substantial division between normotensive and hypertensive subjects. On the contrary, the situational anxiety questionnaires showed a significant difference in the score reading preceding and following a task performed by the hypertensive subjects. We observed significant differences for both systolic and diastolic 24-h blood pressure data in transition from a working situation to the sleeping period. However, there was not a significant difference in hypertensive blood pressure readings recorded during work and at home.(ABSTRACT TRUNCATED AT 250 WORDS)

Detection of a diurnal rhythm in arterial blood pressure in the evaluation of 24-hour antihypertensive therapy.

Uncertainty in defining hypertensive disease makes a prolonged study of blood pressure pattern necessary, using continuous or semicontinuous blood pressure recordings. Its pathophysiological meaning involves data sufficiently indicative of blood pressure profile with reference to the continuous stimulations of different intensity and duration, which are met by subjects both in their daily activities and in the passage from an active life to sleep. Such a parameter is, in fact, an indispensable premise for a correct course of therapy. The aim of our work was at first the detection of a diurnal rhythm in blood pressure, using data obtained in a 24-h ambulatory monitoring away from the conditioning of different activities and daily routine. We have employed three groups of 34 males each. The first group consisted of hypertensive outpatients, while hospitalized subjects comprised the second group. The third group was composed of normal subjects. Furthermore, after finding this system productive, we started studying whether this rhythm of blood pressure could be modified under the influence of a single administered drug dose, and whether information obtained could be easily interpreted. We studied 12 male patients with essential hypertension, which had been untreated. Each patient underwent three 24-h blood pressure ambulatory monitorings. Two different doses of nifedipine (10 and 20 mg) were randomly administered to each of the patients at the beginning of the second and third readings. We observed a significant fall in systolic blood pressure and a minor decrease in diastolic blood pressure after administration of a single 10 mg nifedipine tablet.
