Endothelial progenitor cells predict long-term prognosis in patients with stable angina treated with percutaneous coronary intervention: five-year follow-up of the PROCREATION study.

BACKGROUND: The association between endothelial progenitor cells (EPCs) at the time of percutaneous coronary intervention (PCI) and the subsequent long-term clinical outcome remains undefined. To address this issue, a pre-specified analysis of the PROgenitor Cells role in Restenosis and progression of coronary ATherosclerosis after percutaneous coronary intervention (PROCREATION) study was done. METHODS AND RESULTS: A total of 155 patients with stable angina treated with PCI had flow cytometry before PCI. Patients had a 5-year follow-up. Primary outcome was the composite of major adverse cardiac or cerebrovascular events (MACCE), that is, death, stroke, myocardial infarction, and revascularization. During follow-up, MACCE occurred in 65 of 155 patients (42%). There were no significant differences in clinical and angiographic variables between patients with or without MACCE, apart from a different extent of coronary atherosclerosis. The incidence of MACCE increased significantly over tertiles of CD34+/KDR+/CD45- cells and CD133+/KDR+/CD45- cells, with rates of 25%, 39%, and 69% (P=0.0001), and 26%, 44%, and 59% (P=0.003), respectively. On multivariate analysis it was estimated that the increase in CD34+/KDR+/CD45- cells was associated with a 35% higher risk for MACCE (hazard ratio [HR], 1.75; 95% confidence interval [CI]: 1.07-1.99; P=0.001), and the increase in CD133+/KDR+/CD45- cells was associated with a 25% higher risk for MACCE (HR, 1.35; 95% CI: 1.01-1.74; P=0.03). CONCLUSIONS: Assessment of subpopulations of circulating EPCs in patients with stable angina treated with PCI can improve characterization of long-term prognosis (ClinicalTrials.gov: NCT01575431).

Hypertension in children and adolescents attending a lipid clinic.

UNLABELLED: This study aims to investigate prevalence of hypertension and cardiovascular risk factor clustering in children and adolescents attending a lipid clinic as well as the relationship of their hypertensive status with indicators of fat distribution and parental fat distribution and blood pressure (BP). In this cross-sectional primary prevention study, data on indicators of fat distribution (waist, hip, and middle-upper arm circumferences), body mass index (BMI), BP, high-sensitivity C-reactive protein (hsCRP), lipid and glucose profile of 370 children and adolescents (180 M, 190 F, mean age 9.5 years, (range 6-14 years)) were collected. Parents (502, 251 M, 251 F, age range 28-36 years), who gave their informed consent, underwent BMI, fat distribution, and BP measurements. There were 131 (35.4 %) hypercholesterolemic subjects and 72 (19.5 %) hypertensives. Using tests on medians, in comparison with 298 normotensives, the 72 hypertensives had higher levels of insulin (p<0.005) and no differences in cholesterol levels, age, and height. BMI and all the indicators of fat distribution were significantly higher (all p<0.01) in hypertensives than normotensives. BMI and waist circumferences were higher (both p<0.05) in the mothers of hypertensives, but not in the fathers. Hypertensive subjects' BMI was related to mothers' hip and waist circumferences (r=0.28 and 0.21, respectively). CONCLUSIONS: In this study, children's hypertension was a component of the metabolic syndrome, but uric acid and hsCRP levels were not contributive. This hemodynamic and metabolic disorder was related to maternal fat distribution and BMI suggesting an epigenetic etiology.

Transcatheter aortic valve implantation results are not superimposable to surgery in patients with aortic stenosis at low surgical risk.

BACKGROUND: The aim of this meta-analysis was to compare the impact of transcatheter aortic valve implantation (TAVI) vs. surgical aortic valve replacement (SAVR) in patients with severe aortic valve stenosis (AS) at low surgical risk. METHODS: All randomized controlled trials (RCTs) and observational studies (Obs) published from January 2014 until March 31st, 2020 were retrieved through the PubMed computerized database and at the site https://www. CLINICALTRIALS: com. The relative risk (RR) with the 95% confidence interval (CI) was used to evaluate the effect of the intervention under comparison. The primary endpoints were all-cause 30-day mortality and 1-year mortality. The 30-day safety endpoints were: stroke, acute kidney injury stage 2 or 3, major bleeding, moderate/severe paravalvular leak, need for new permanent pacemaker (PM) implantation. RESULTS: After detailed review 9 studies, related to 4 RCTs and 5 Obs, were selected. The overall analysis of RCTs plus Obs showed a significantly lower 30-day mortality for TAVI (RR = 0.55; 95% CI 0.45-0.68, p < 0.00001; I2 = 0%). However, an increased risk of new PM implantation (RR = 2.87; 95% CI 2.01-3.67, p < 0.00001, I2 = 0%) and of paravalvular leak (RR = 7.28; 95% CI 3.83-13.81, p < 0.00001, I2 = 0%) was observed in TAVI compared to SAVR. On the contrary, a lower incidence of major bleeding (RR = 0.38; 95% CI 0.27-0.54, p < 0.00001, I2 = 0%) and of acute kidney injury was observed (RR = 0.33; 95% CI 0.19-0.56, p < 0.0001, I2 = 0%) in TAVI. CONCLUSIONS: TAVI and SVAR in the treatment of AS in the patients at low surgical risk are not superimposable. In particular, if 30-day and 1-year mortality, major bleeding and acute kidney injury were significantly lower for TAVI, the need of new PM implantation and paravalvular leak were significantly lower in SAVR. Consequently, we suggest the need of more trials to evaluate the effectiveness of TAVI as routine therapeutic procedure in the treatment of patients with low surgical risk AS.

Myocardial Metastasis of Tongue Cancer: A Rare Localization.

BACKGROUND Cardiac metastases of head and neck tumors are extremely rare, and antemortem diagnosis is even rarer. In most cases, patients show symptoms or electrocardiographic abnormalities and expected survival is considerably low. CASE REPORT A 72-year-old man was admitted to our cardiology ward with suspected endocarditis 2 months after a right hemiglossectomy for a squamous cell carcinoma. He was asymptomatic and showed no electrocardiogram abnormalities. Echocardiography showed an iso-ipoechogenic round-shaped formation at the right ventricle apex that was suspected to be a metastasis owing to 2 cardiac magnetic resonance imaging examinations showing a significant increase in its volume over 14 days. The patient was evaluated by a multidisciplinary team and referred for first-line chemotherapy with carboplatin, 5-fluoruracil, and cetuximab. He died after almost 4 months of follow-up. CONCLUSIONS This case presents a very rare diagnosis as well as some unique features, including the intramyocardial localization, the absence of symptoms, and electrocardiogram abnormalities. Our report shows the relevance of imaging techniques in defining even the most unusual clinical findings, and it emphasizes the significance of early recognition of cardiac masses in order to identify the appropriate medical or surgical therapy for patients.

Acute atrial ischemia associates with early but not late new-onset atrial fibrillation in STEMI patients treated with primary PCI: relationship with in-hospital outcomes.

BACKGROUND: New-onset atrial fibrillation (NOAF), both early (EAF) or late (LAF), may complicate ST-segment elevation myocardial infarction (STEMI). The mechanisms underlying EAF or LAF are poorly described. We investigated atrial branch occlusion and EAF or LAF onset in STEMI patients undergoing primary percutaneous coronary intervention. METHODS: This was a retrospective cohort study including 155 STEMI patients. Patients were divided into 3 groups: sinus rhythm (SR), EAF, or LAF. Clinical characteristics, angiographic features including occlusion of atrial branches, namely ramus ostia cavae superioris (ROCS), atrio-ventricular node artery (AVNA), right intermediate atrial artery (RIAA), and left intermediate atrial artery, were assessed. We also investigated in-hospital adverse events (AEs) and death. RESULTS: Mean age was 63.8±11.9 years; 78.7% were men. NOAF was detected in 22 (14.2%) patients: 10 (6.4%) EAF and 12 LAF (7.7%). Compared to EAF, LAF patients were older (p=0.013), with higher GRACE risk score (p=0.014) and Killip class (p=0.015), depressed ejection fraction (p=0.007), elevated filling pressures (p=0.029), higher C-reactive protein (p=0.014) and more with thrombolysis in myocardial infarction flow <3 (p=0.015). Compared to SR, EAF was associated with higher prevalence of occluded ROCS (p=0.010), AVNA (p=0.005), and RIAA (p<0.001). Moreover, EAF patients had more frequently ≥2 diseased atrial branches than SR (19.5%, p<0.001) and LAF (25%, p<0.030) patients. LAF patients had a higher in-hospital AEs (p=0.019 vs SR; p=0.029 vs EAF) and death (p=0.004 vs SR). CONCLUSIONS: The occlusion of atrial branches is associated with EAF but not LAF following STEMI. LAF patients had worse in-hospital AEs and mortality.

Clinical frailty and triggers in Takotsubo syndrome: the notable role of a new classification.

AIMS: Takotsubo syndrome (TTS) is a mainly transient and acute heart failure mimicking an acute coronary syndrome. Originally described in postmenopausal women, over time TTS has been associated with an increasingly advanced age. Emotional and physical triggers precipitating TTS have been correlated in most cases. The aim of our work was to detect differences between patients with or without recognizable triggers preceding the onset of symptoms. METHODS: We enrolled 22 consecutive patients. They were all women with an average age of 71 ±â€Š12 (range 40-90) years. Twelve patients correlated the onset of TTS symptoms with a trigger (group 1) and 10 patients (group 2) denied any correlation with stressful events. RESULTS: Patients in group 1 showed a higher average age than group 2 (76 ±â€Š10 vs. 64 ±â€Š12 years; P = 0.023), a longer hospitalization period (22 ±â€Š12 vs. 11 ±â€Š10 days; P = 0.01) and greater value of frailty score (P = 0.004). Despite a decrease and subsequent recovery of systolic function, there was no significant difference between groups. Group 1 showed a longer corrected QT (QTc) (505 ±â€Š53 vs. 453 ±â€Š42 ms, P = 0.03), a greater decrease in QTc at discharge (-57 ±â€Š44 vs. 0.3 ±â€Š39 ms; P = 0.004), with the result that at discharge both groups showed a comparable QTc. CONCLUSION: Our results emphasized that typical TTS female patients with precipitating triggers have advanced age, clinical frailty and QTc abnormalities.

Prognostic relevance of masked hypertension in subjects with prehypertension.

BACKGROUND: The prognostic impact of masked hypertension is not yet completely clear. The aim of this study was to evaluate the prognostic relevance of masked hypertension in subjects with prehypertension. METHODS: The occurrence of fatal and nonfatal cardiovascular events was evaluated in 591 subjects with prehypertension defined as clinic blood pressure (BP) in the range of 120-139 mm Hg for systolic BP and 80-89 mm Hg for diastolic BP. Among them, 471 were classified as having true prehypertension (clinic BP <140/90 mm Hg and daytime BP <135/85 mm Hg) and 120 as having masked hypertension (clinic BP <140/90 mm Hg and daytime BP > or =135 or 85 mm Hg). RESULTS: During the follow-up (6.6 +/- 4.3 years, range 0.5-15.5 years), 29 cardiovascular events occurred. In subjects with true prehypertension and masked hypertension the event-rates per 100 patient-years were 0.57 and 1.51, respectively. Event-free survival was significantly different between the groups (P < 0.005). After adjustment for other covariates, including clinic BP (forced into the model), Cox regression analysis showed that cardiovascular risk was significantly higher in masked hypertension than in true prehypertension (masked vs. true prehypertension, relative risk 2.65, 95% confidence interval 1.18-5.98, P = 0.018). CONCLUSIONS: Among subjects with prehypertension, those with masked hypertension are at higher cardiovascular risk than those with true prehypertension. Out-of-office BP should be known in individuals with prehypertension, preferably by ambulatory BP monitoring or alternatively by home BP measurement, to obtain a better prognostic stratification.

Optimal drug treatment of systolic hypertension in the elderly.

Approximately two-thirds of the elderly population has hypertension, mainly of the isolated systolic hypertension (ISH) type. However, while large-scale, randomized controlled intervention trials have demonstrated that treatment of ISH reduces rates of total mortality, cardiovascular mortality and stroke in older hypertensives, control of ISH in the elderly remains poor. The aim of this review of drug treatment of ISH in the elderly is to provide a succinct, practical and clinically orientated guide that summarizes international recommendations and practices with special emphasis on newer approaches. Knowledge of pathophysiological changes in older subjects (decreased elastic artery compliance, reduced plasma renin activity, increased salt sensitivity) and evidence from epidemiological surveys and randomized controlled trials give clear clues that thiazide(-like) diuretics and long-acting dihydropyridine calcium channel antagonists are the drugs of choice in the treatment of ISH. Thus, based on this evidence, American, European and international guidelines for hypertension management still offer the best available recommendations for optimal treatment of ISH in the elderly. Newer combination treatments, especially the fixed combination of a dihydropyridine calcium channel antagonist and an ACE inhibitor, have valuable benefits in terms of efficacy and tolerability. Use of nitrates added to other antihypertensive medications can provide the practising physician with a further unconventional therapeutic strategy.

Two cases of acute chest discomfort and the Central Italy earthquake.

We present the cases of two postmenopausal women presenting to our emergency department with acute chest discomfort soon after the Central Italy earthquake. Different diagnoses were made in the two patients. The role of the earthquake as a stressful event triggering diverse chest pain syndromes is discussed.

Epigenetics and cardiovascular risk in childhood.

Cardiovascular disease (CVD) can arise at the early stages of development and growth. Genetic and environmental factors may interact resulting in epigenetic modifications with abnormal phenotypic expression of genetic information without any change in the nucleotide sequence of DNA. Maternal dietary imbalance, inadequate to meet the nutritional needs of the fetus can lead to intrauterine growth retardation, decreased gestational age, low birth weight, excessive post-natal growth and metabolic alterations, with subsequent appearance of CVD risk factors. Fetal exposure to high cholesterol, diabetes and maternal obesity is associated with increased risk and progression of atherosclerosis. Maternal smoking during pregnancy and exposure to various environmental pollutants induce epigenetic alterations of gene expression relevant to the onset or progression of CVD. In children with hypercholesterolemia and/or obesity, oxidative stress activates platelets and monocytes, which release proinflammatory and proatherogenic substances, inducing endothelial dysfunction, decreased Doppler flow-mediated dilation and increased carotid intima-media thickness. Primary prevention of atherosclerosis should be implemented early. It is necessary to identify, through screening, high-risk apparently healthy children and take care of them enforcing healthy lifestyle (mainly consisting of Mediterranean diet and physical activity), prescribing nutraceuticals and eventual medications, if required by a high-risk profile. The key issue is the restoration of endothelial function in the reversible stage of atherosclerosis. Epigenetics may provide new markers for an early identification of children at risk and thereby develop innovative therapies and specific nutritional interventions in critical times.

Ivabradine in Patients with ST-Elevation Myocardial Infarction Complicated by Cardiogenic Shock: A Preliminary Randomized Prospective Study.

BACKGROUND AND OBJECTIVE: An elevated heart rate (HR) is an independent risk factor for mortality and morbidity in patients with acute heart failure (HF). The purpose of this study was to evaluate the impact of ivabradine, a selective HR-lowering agent, in patients with cardiogenic shock (CS) complicating ST-elevation acute myocardial infarction (AMI). METHODS: Patients with post-AMI CS were randomized to standard treatment (SDT, 28 patients) or to standard treatment plus ivabradine (I + SDT, 30 patients). In the presence of orotracheal intubation (OTI), ivabradine was administered by nasogastric intubation. HR, BP, New York Heart Association (NYHA) class, NT-proBNP, left ventricular ejection fraction (LVEF) and diastolic function (LVDF) were monitored at specific times after the onset of AMI. The primary (surrogate) end-point was the in-hospital halving of plasma NT-proBNP levels. The secondary end-points were cardiovascular death, hospital re-admission for worsening HF, and clinical and haemodynamic improvement. RESULTS: Treatment groups were statistically similar with regard to age, gender distribution, cardiovascular risk factors, number of diseased vessels and overall treated lesions, AMI site and occurrence of OTI. In-hospital mortality was double in the SDT group in comparison with the I + SDT group (14.3 vs. 6.7 %), but the difference was not statistically significant. HR, BP, NT-proBNP and LVEF favorably changed in both groups, but the change was more relevant in the I + SDT group. LVDF significantly changed only in the I + SDT group (p < 0.01). Patients in the I + SDT group did not experience adverse effects. CONCLUSION: Ivabradine in CS complicating AMI is safe, is associated with a short-term favourable outcome and can be effectively administered by nasogastric intubation.

Multidetector computed tomography of the coronary arteries.

Over the past decades, the feasibility of non-invasive coronary imaging has been explored using different modalities, such as magnetic resonance and electron beam computed tomography. Despite encouraging initial results, neither technique is yet considered suitable for routine clinical use. Recent developments in multidetector computed tomography have expanded the potential of contrast-enhanced spiral computed tomography coronary angiography. Promising results have been published with the use of 4-slice spiral computed tomography; however, cardiac motion and calcium deposits in the artery wall rendered a substantial number of scans inadequate for interpretation. Recently, a new generation of scanners, equipped with more and thinner detector rows (8 and 16 detectors) and an increased rotation speed, have been introduced. These technical advances will have a significant impact on cardiac imaging: at an increased gantry rotation rate, up to 32 slices can be acquired in 1 s. The improved spatial and temporal resolutions have led to the opportunity of acquiring high-quality images of the entire heart within a single breath-hold.

[Multiculturalism and cardiovascular diseases]. / Multiculturalismo e malattie cardiovascolari.

Immigration has increased drastically to the point of becoming an ordinary structure of our society. Once in Italy, the immigrant's health is compromised rapidly due to a series of conditions and illnesses that exist in our country: lack of work, inadequate salary, inappropriate residence, lacking family support, climate changes, nutritional differences. Cardiovascular illnesses represent 7.6% of the diseases of the immigrants, and cause 36.6% of deaths. The risk factors that affect the genesis of cardiovascular diseases include: subjective factors (age, ethnic group), environmental, nutritional and pathological (arterial hypertension, AIDS, tuberculosis, alcohol). The challenge for our time is to design a new solidarity model to promote cultural and social integration in order to meet the multiethnical and multiracial needs of western society. This model should permit reconsideration of doctor-patient relationship in order to build a real intercultural society.

Metabolic syndrome among children and adolescents from Southern Italy: contribution from the Calabrian Sierras Community Study (CSCS).

Among 1657 children and adolescents aged 6 to 14 years (787, 47% girls and 870, 53% boys) from primary and secondary schools in a 14-town Southern Italian community, HDL cholesterol (54 ± 15 mg/dl), triglycerides (61 ± 29 mg/dl), blood glucose (78 ± 10 mg/dl), systolic (101 ± 11 mm Hg) and diastolic (62 ± 10 mm Hg) blood pressures, waist circumference (WC) (66 ± 10 cm) and WC/height (0.46 ± 0.006) and triglycerides/HDL cholesterol (1.31 ± 0.99) ratios were measured. The distributions were similar in both genders. Age did not affect triglycerides/HDL cholesterol ratio, whereas there was a slightly positive correlation (p<0.00001) between WC/height and triglycerides/HDL cholesterol ratios. We present individual gender and age specific percentile distributions (as Supplementary materials). Using percentile cut-offs (≤ 10th for HDL cholesterol and ≥ 90th for the other components), there were 183 (11%) children or adolescents with low HDL cholesterol, 162 (9.77%) with high triglycerides, 178 (10.74%) with high blood glucose, 178 (10.74%) with high WC, 244 (20.76%) with high systolic or diastolic BP and 126 (7.6%) with high systolic and diastolic BP. Abnormally high BP was seen in 470 (28.36%) children or adolescents. Using abnormal percentile values of 3 of 5 of its components, metabolic syndrome (MS) was diagnosed in 70 (4.2%) subjects, similarly in both genders. To assess out-of-limit distributions of all 5 individual MS components in children and adolescents gender- and age-distributions derived from local epidemiological data should be used: these distributions are presented and they might now be used both for comparative and applicative purposes at least in Southern Europe.

Arterial blood pressure and serum lipids in a population of children and adolescents from Southern Italy: the Calabrian Sierras Community Study (CSCS).

BACKGROUND: Lipid standards in Italy are lacking in children and adolescents whereas those for blood pressure (BP) were derived from US surveys. METHODS: In a 14-town community in Southern Italy 1657 (64%) of 2594 children aged 6-14 years were enrolled and anthropometric, BP, lipid and glucose serum levels were obtained. RESULTS: Average systolic BP was 101 ± 11 (60-150) mm Hg and cholesterol (CholT) level was 156 ± 28 (57-264) mg/dl. There were positive (p<0.00001) age-trends for systolic BP and body mass index (BMI) in both genders whereas age-trends for CholT and heart rate were negative (p<0.00001). A negative age-trend in both genders was also seen for non-HDL cholesterol (p<0.03). Based on 95% percentile gender and age distributions, there were 177 (10.68%) hypertensive (HT) and 82 (4.94%) hypercholesterolemic (HC) children or adolescents. Univariately, HT had higher (p<0.00001) height, weight, BMI, arm circumference, hips, waist, diastolic BP and waist/height, whereas HC had higher LDL-, HDL and non-HDL-cholesterol and triglycerides (p<0.01). Systolic BP was predicted (r(2)=0.2810, p=0.00001) by age (t=2.319, p<0.0205), male gender (t=3.179, p<0.0015), glucose (t=2.357, p<0.0186), height (t=2.473, p<0.0135), arm circumference (t=3.313, p<0.0009) and heart rate (t=4.161, p<0.00001). CholT was related inversely (r(2)=0.1399, p=0.00001) to height (t=-3.928, p<0.0001), weight (t=-3.922, p<0.0001) and waist/height (t=-4.797, p<0.00001) and directly to BMI (t=3.064, p<0.0022), waist (t=5.149, p<0.0000), triglycerides (t=11.332, p<0.00001) and female gender (t=-2.041, p<0.0414). CONCLUSION: In these Southern Italian children and adolescents systolic BP and CholT are related with anthropometric and other variables, not confined to height. BP is lower than previously reported.

Low dose chromium-polynicotinate or policosanol is effective in hypercholesterolemic children only in combination with glucomannan.

OBJECTIVE: A low-fat, fiber-rich diet is the first step in the management for hypercholesterolemic children. Glucomannan (GM) is a natural fiber that has been demonstrated to lower total and LDL-cholesterol. The use of high-dose chromium-polynicotinate (CP) and policosanol (PC) has also shown cholesterol-lowering benefits. We aimed at investigating the effects of low-dose CP or PC and their GM combination in hypercholesterolemic children. METHODS: A double-blind trial was conducted in 120 children (60 M, 60 F, 9 ± 4 years, median 9.6 years, range: 3-16 years) randomly assigned to 5 neutraceutical and 1 placebo (only resistant starch) 8-week treatment groups. Fasting blood glucose (FBG), total cholesterol (CholT), triglycerides (TG), HDL and LDL cholesterol were considered. RESULTS: GM combination of low-dose CP or PC reduced CholT and LDL without changing HDL, TG and FBG. The highest post-treatment changes were seen after GM combination with CP (CholT 85 ± 3% and LDL 85 ± 5%, of pretreatment) which was significantly (p < 0.01) less than with low-dose CP or PC and starch. When GM was associated with starch, there was no lipid lowering effect, which was an unexpected finding as compared to previous data with GM and no starch. No adverse effects were reported. CONCLUSION: This is the first report to show the cholesterol-lowering efficacy of GM combined treatment with low-dose CP or PC. Further studies are needed to investigate the best combinations and doses of nutraceutics to be added to the standard GM treatment. The potential negative association of GM and nutraceutics with starch is clearly shown.

Ambulatory blood pressure monitoring in prehypertensive subjects.

BACKGROUND: Although treatment of prehypertensives is feasible and effective, it is unclear how to define those who may benefit. We hypothesized that ambulatory blood pressure monitoring (ABPM) might be a tool for selecting prehypertensive subjects, classified according to the JNC 7, who later develop drug-treated hypertension. METHODS: Prehypertensives (n=107; 62 M, 45 F; age 50 ± 14 years) with or without cardiovascular risk factors were assessed for drug-treated hypertension development. They underwent ABPM at entry examination and were clinically followed-up for an average of 99 ± 42 months. Thereafter, subjects were divided into 2 groups according to the development of drug-treated hypertension. Stepwise logistic regression (LR) analysis was performed to assess the role of factors contributing independent prediction of outcome (i.e. drug-treated hypertension onset). RESULTS: In LR analysis body mass index [odds ratio (OR)=1.29, confidence intervals (CI)95% 1.03-1.62], female gender (OR=11.10, CI95% 2.66-46.30), total cholesterol (OR=1.03, CI95% 1.01-1.05), smoking (OR=3.90, CI95% 0.94-16.20), daytime SBP (OR=1.10, CI95% 1.01-1.19) and 24h DBP (OR=1.23, CI95% 1.08-1.41) predicted the development of hypertension. The criteria combining BP and clinical variables were superior to BP or clinical criteria alone in the correct classification of true positives and true negatives. Altogether there was an improvement of 14.02% (p < 0.01) in comparison to only clinical criteria. CONCLUSIONS: In the setting of global cardiovascular risk assessment, ABPM, in the early diagnosis of hypertension in prehypertensive individuals, appears as a useful tool, both diagnostically and prognostically, to index subjects who are suspected to be masked hypertensives.

Visualization of coronary arteries and coronary stents by low dose 320-slice multi-detector computed tomography in a patient with atrial fibrillation.

Cardiac multi-detector computed tomography (MDCT) is widely used in the diagnosis of coronary disease. However, the predictive value of this technique is limited in the presence of atrial fibrillation and coronary stents. Here we present a case showing the ability of the new 320-slice MDCT to assess coronary anatomy in a patient with atrial fibrillation and coronary stents.
