RESUMO
Out-of-office blood pressure (BP) measurement is considered an integral component of the diagnostic algorithm and management of hypertension. In the era of digitalization, a great deal of wearable BP measuring devices has been developed. These digital blood pressure monitors allow frequent BP measurements with minimal annoyance to the patient while they do promise radical changes regarding the diagnostic accuracy, as the importance of making an accurate diagnosis of hypertension has become evident. By increasing the number of BP measurements in different conditions, these monitors allow accurate identification of different clinical phenotypes, such as masked hypertension and pathological BP variability, that seem to have a negative impact on cardiovascular prognosis. Frequent measurements of BP and the incorporation of new features in BP variability, both enable well-rounded interpretation of BP data in the context of real-life settings. This article is a review of all different technologies and wearable BP monitoring devices.

OBJECTIVE: Various biomarkers have been studied in the early post-kidney transplantation (post-KTx) period in order to identify potential therapeutic targets for improving long-term graft survival. Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a biomarker that has recently gained interest in cardiovascular disease but its role still remains to be defined post-KTx. PATIENTS AND METHODS: We prospectively evaluated the levels of PCSK9, interleukin (IL)-6, WBC and C-reactive protein in seventy-three hemodialysis patients undergoing KTx, at 3 time-points; pre-transplantation (day 0) and at 1 and 6-months post-KTx. All data were also analyzed according to donor-type (living or deceased) and compared with hemodialysis patients on transplant waiting list. RESULTS: At Day 0 there was no difference in WBC, CRP, IL-6 and PCSK9 levels between patients scheduled for transplantation and those who remained on hemodialysis. In transplanted patients WBC, CRP and IL-6 levels were significantly reduced early post-KTx [logIL-6 Day 0: 0.68 (0.33, 0.85) vs. 1-month: 0.57 (0.37, 0.75) vs. 6-months: 0.50 (0.32, 0.69) pg/ml, p=0.01], while PCSK9 levels were significantly increased (Day 0: 199.8±63.0 vs. 1-month: 276.2±79.4 vs. 6-months: 245.9±62.5 ng/ml, p<0.001). In contrast, no change of WBC, CRP, IL-6 and PCSK9 levels was observed in hemodialysis patients on follow-up (p=NS for all). Between living-donor and deceased-donor recipients, analysis showed reduced CRP and increased PCSK9 levels in both groups (p<0.05 for all), while IL-6 levels were reduced in living-donor and increased in deceased-donor recipients 1-month post-KTx. PCSK9 levels were not correlated with renal function, delayed graft function, rejection episodes or inflammatory biomarkers. CONCLUSIONS: PCSK9 levels were increased post-KTx independently from renal function and inflammatory biomarkers, in both living and deceased-donor recipients.

BACKGROUND AND AIMS: We assessed the association of Mediterranean diet with NAFLD and their interaction in predicting ten-year diabetes onset and first fatal/non-fatal cardiovascular disease (CVD) incidence. METHODS: The ATTICA prospective observational study in Athens, Greece included 1,514 men and 1,528 women (>18 years old) free-of-CVD at baseline. Liver steatosis and fibrosis indices were calculated. Mediterranean diet adherence was assessed through MedDietScore. At the ten-year follow-up visit, CVD evaluation was performed in an a priori specified subgroup of n = 2,020 participants and diabetes onset in n = 1,485 free-of-diabetes participants. RESULTS: MedDietScore was inversely associated with steatosis and fibrosis; e.g. in the case of the TyG index the Odds Ratio (OR) of the 3rd vs. 1st MedDietScore tertile was = 0·53, [95% Confidence Interval (95% CI) (0·29, 0·95)] and the associations persisted in multi-adjusted models. NAFLD predicted incident diabetes prospectively over a ten year period [HR = 1·87, 95% CI (0·75, 4·61)] and the association remained significant only in subjects with low MedDietScore (below median) whereas diabetes onset among subjects with higher MedDietScore was not influenced by NAFLD. Similarly, NAFLD predicted CVD [Hazard Ratio (HR) = 3·01, 95%CI(2·28, 3·95)]; the effect remained significant only in subjects with MedDietScore below median [HR = 1·38, 95% CI (1·00, 1·93)] whereas it was essentially null [HR = 1·00,95% CI (0·38, 2·63)] among subjects with higher score. Mediation analysis revealed that adiponectin and adiponectin-to-leptin ratio were the strongest mediators. CONCLUSIONS: We report an inverse association between Mediterranean diet and NAFLD. Mediterranean diet protected against diabetes and CVD prospectively among subjects with NAFLD.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) outbreak, along with implementation of lockdown and strict public movement restrictions, in Greece has affected hospital visits and admissions. We aimed to investigate trends of cardiac disease admissions during the outbreak of the pandemic and possible associations with the applied restrictive measures. STUDY DESIGN: This is a retrospective observational study. METHODS: Data for 4970 patients admitted via the cardiology emergency department (ED) across 3 large-volume urban hospitals in Athens and 2 regional/rural hospitals from February 3, 2020, up to April 12 were recorded. Data from the equivalent (for the COVID-19 outbreak) time period of 2019 and from the postlockdown time period were also collected. RESULTS: A falling trend of cardiology ED visits and hospital admissions was observed starting from the week when the restrictive measures due to COVID-19 were implemented. Compared with the pre-COVID-19 outbreak time period, acute coronary syndrome (ACS) [145 (29/week) vs. 60 (12/week), -59%, P < 0.001], ST elevation myocardial infarction [46 (9.2/week) vs. 21 (4.2/week), -54%, P = 0.002], and non-ST elevation ACS [99 cases (19.8/week) vs. 39 (7.8/week), -60% P < 0.001] were reduced at the COVID-19 outbreak time period. Reductions were also noted for heart failure worsening and arrhythmias. The ED visits in the postlockdown period were significantly higher than in the COVID-19 outbreak time period (1511 vs 660; P < 0.05). CONCLUSION: Our data show significant drops in cardiology visits and admissions during the COVID-19 outbreak time period. Whether this results from restrictive measures or depicts a true reduction of cardiac disease cases warrants further investigation.

PURPOSE OF REVIEW: Hypertension affects approximately 10% of pregnancies and may persist in the postpartum period. Furthermore, de novo hypertension may present after delivery, but its exact prevalence is not verified. Both types of hypertension expose the mother to eventually severe complications like eclampsia, stroke, pulmonary edema, and HELLP (hemolysis, elevated liver enzymes, low platelet) syndrome. RECENT FINDINGS: Until today, there are limited data regarding the risk factors, pathogenesis, and pathophysiology of postpartum hypertensive disorders. However, there is certain evidence that preeclampsia may in large part be responsible. Women who experienced preeclampsia during pregnancy, although considered cured after delivery and elimination of the placenta, continue to present endothelial and renal dysfunction in the postpartum period. The brain and kidneys are particularly sensitive to this pathological vascular condition, and severe complications may result from their involvement. Large randomized trials are needed to give us the evidence that will allow a timely diagnosis and treatment. Until then, medical providers should increase their knowledge regarding hypertension after delivery because many times there is an underestimation of the complications that can ensue after a misdiagnosed or undertreated postpartum hypertension.

BACKGROUND: Within-visit variability of repeated sequential readings of blood pressure (BP) is an important phenomenon that may affect precision of BP measurement and thus decision making concerning BP-related risk and hypertension management. However, limited data exist concerning predictive ability of within-visit BP variability for clinical outcomes. Therefore, we aimed to investigate the association between the variability of three repeated office BP measurements and the risk of all-cause mortality, independent of BP levels. METHODS: Data collected through the National Health and Nutrition Examination Survey (NHANES) were analysed. NHANES is a program of studies designed to assess health and nutritional status of adults and children in the United States. A complete set of three sequential BP measurements, together with survival status, were available for 24969 individuals (age 46.8±;19.3 years, 49% males). Multivariable logistic regression models were used to determine the prognostic ability of the examined demographic, clinical, and haemodynamic indices. RESULTS: Among various examined indices of variability of systolic (SBP) and diastolic (DBP) blood pressure measurements, the standard deviation of DBP (DBPSD) was the stronger independent predictor of mortality (odds ratio 1.064, 95% Confidence Interval: 1.011-1.12) after adjustment for age, sex, body mass index, smoking, SBP, heart rate, history of hypertension, diabetes mellitus, hypercholesterolaemia, and cardiovascular events. CONCLUSION: Within-visit variability of three sequential office DBP readings may allow for the identification of high-risk patients better than mean SBP and DBP levels. The predictive value of within-visit BP variability and methods to improve its clinical application are worthy of further research.

BACKGROUND: The present study aimed to evaluate the association between dietary vitamin D intake and 10-year first fatal/nonfatal cardiovascular disease (CVD), conventional CVD risk factors and surrogate markers related to inflammation, coagulation, insulin resistance, liver and renal function. METHODS: The ATTICA study was conducted during 2001-2012 including 1514 men and 1528 women (aged >18 years) from the greater Athens area, Greece. Dietary assessment was based on a validated semi-quantitative food frequency questionnaire. Daily intake of vitamin D was calculated using a standardised food database. Follow-up (2011-2012) was achieved in 2020 participants (n = 317 cases). RESULTS: Ranking from first to third vitamin D tertile, CVD events were 24%, 17% and 12% for men (P = 0.002) and 14%, 10% and 11% for women (P = 0.59). Inverse associations between vitamin D and CVD in total sample [hazard ratio (HR) = 0.76 95% confidence interval (CI) = 0.60-0.97] and in men (HR = 0.66 95% CI = 0.49-0.89) were observed, and lost after adjusting for inflammation/coagulation markers; for women, no significant trends were observed. Regarding 10-year onset of conventional risk factors, inverse associations of vitamin D with hypertension in men (HR = 0.62 95% CI = 0.39-0.99) and transition to metabolically unhealthy status in women (HR = 0.69 95% CI = 0.51-0.93) were observed. Significant inverse associations for C-reactive protein, interleukin-6 and fibrinogen in both sexes, whereas these were revealed only in women for insulin resistance. CONCLUSIONS: Contradicting the neutral/modest associations in vitamin-D supplementation trials, increased food-generated vitamin D may protect against hard and intermediate CVD endpoints, implying different paths between sexes.

BACKGROUND: It has been long hypothesized that emotional factors and depression may play role in the development of cardiovascular diseases. AIM: The aim of this study was to examine the association between depression, arterial stiffness and atheromatic burden in carotid arteries. DESIGN AND METHODS: Corinthia study is a cross-sectional epidemiological study conducted in subjects aged 40-99 years, inhabitants of the homonym region of Greece. Intima media thickness (IMT) was measured in the left and right common carotid artery, carotid bulb and internal carotid artery. The average of the measurements (mean IMT) and the maximum IMT were determined as the representative value of carotid atherosclerosis burden. Pulse wave velocity was used to evaluate arterial stiffness. The Zung Self-Rating Depression Scale was used to evaluate depressive symptoms in subjects <65 years and the Geriatric Depression Scale in those >65 years. RESULTS: In this analysis, we included data from 1510 participants. In older subjects (i.e. >65 years), maximum IMT was significantly increased in subjects with depression compared to those without (1.57 ± 0.97 mm vs. 1.74 ± 1.05 mm, P = 0.04). Similarly, the prevalence of atheromatic plaques was higher in subjects with depression (46% vs. 34%, P = 0.005). In the younger subgroup (<65years), there was no difference in mean and maximum IMT. Pulse wave velocity was found higher in the presence of depression (8.35 ± 2.36m/s vs. 7.88 ± 1.77m/s, P = 0.007). No differences emerged for the rest of the variables assessed in the individual subgroups. CONCLUSIONS: There is an age-dependent association between depression, arterial stiffness and carotid atheromatic burden highlighting the interplay between cardiovascular diseases and emotional status.

BACKGROUND AND PURPOSE: Even though new cancer therapies have improved the overall survival, in some cases they have been associated with adverse effects, including increased cardiotoxicity. The purpose of the present study was to assess the cardiovascular effects of adjuvant chemotherapy for colorectal cancer and mainly the impact on arterial stiffness indices. MATERIAL AND METHODS: A total of 70 patients with non-metastatic colorectal cancer who were treated either with FOLFOX (n=16) or with XELOX (n=54) adjuvant chemotherapy were included in the study. All patients were subjected to full cardiovascular evaluation at the beginning and the end of chemotherapy. Arterial stiffness was assessed by means of pulse wave velocity (PWV) and augmentation index (Aix) and full laboratory examinations were conducted prior to, and soon after, the termination of chemotherapy. RESULTS: Patients exhibited significantly higher levels of carotid-radial PWV, carotid femoral RWV and Aix post-chemotherapy (p<0.001); these findings remained significant when examined separately in each treatment subgroup (FOLFOX, XELOX). The observed changes were independent of treatment regimen and baseline patient characteristics. Univariate regression analyses showed that baseline PWVc-r and PWVc-f were the only factors associated with PWVc-r and PWVc-f change, while Aix change was independent of its baseline value. CONCLUSION: There is a clear burden in arterial stiffness indices post-adjuvant chemotherapy for colorectal cancer in both chemotherapy groups. This is a finding of important clinical significance, however more prospective studies are required in order to encode the possible mechanisms involved.

BACKGROUND AND AIMS: Predictive and prognostic ability of muscle mass in CVD settings is increasingly discussed. The gender-specific effect of skeletal muscle mass index (SMI) on 10-year recurrent fatal/non fatal cardiovascular disease (CVD) event of acute coronary syndrome (ACS) patients was evaluated. METHODS AND RESULTS: In 2006-2009, n = 1000 consecutive patients (n = 222 women), hospitalized at the First Cardiology Clinic of Athens with ACS diagnosis and with symptoms and left ventricular function indicative of heart failure were selected. SMI was created to reflect skeletal muscle mass through appendicular skeletal muscle mass (indirectly calculated through population formulas) divided by body mass index (BMI). In the 10-year follow-up (2016), 55% of ACS patients experienced recurrent fatal/non fatal CVD events (53% in women vs.62% in men, p = 0.04). Patients in the 2nd SMI tertile (mostly overweight) had 10% lower risk for CVD recurrence (women:men rate ratio = 0.87) over their counterparts in the 1st (mostly normalweight) and 3rd tertile (mostly obese). Multivariate analysis revealed that ACS patients in the 2nd SMI tertile presented 46% and 85% lower CVD event risk over their counterparts in the 1st tertile (Hazard Ratio (HR) = 0.54, 95% Confidence Interval (95% CI) 0.30, 0.96, p = 0.002) and 3rd tertile (HR = 1.85, 95%CI 1.05, 2.94, p = 0.03). Gender-based analysis revealed that this trend remained significant only in women. Inflammatory markers had strong confounding effect. CONCLUSION: A U-shape association between SMI and 10-year CVD event especially in women was highlighted. This work reveals gender-specific remarks for "obesity-lean paradox" in secondary prevention, implying that high muscle mass accompanied by obesity and excess adiposity may not guarantee better prognosis.

Heart rate is an important factor in coronary artery disease and its manifestations, and as such has been considered as a possible target for therapy. Although in epidemiological, and in less degree, in clinical studies derived indications of a possible pathogenetic role of heart rate in major cardiac diseases, clinical trials did not provided any strong evidence. However, even as a simple risk marker, remains important in the treatment of coronary artery disease and heart failure. Beta-blockers are the drugs most frequently used for heart rate control. However, recent studies constantly find insufficient effectiveness of beta-blockers in heart rate control and go further to question their efficacy on outcomes, making clear the need for an additional therapy. Ivabradine, a pure heart rate inhibitor, added to classic beta-blocker treatment represent the new therapeutic option in stable coronary disease and heart failure.

BACKGROUND: Transesophageal echocardiography (TEE) plays a unique role in transcatheter closure of atrial septal defects (ASD) and patent foramen ovale (PFO). However, problems such as the need for general anesthesia, possible trauma from endotracheal intubation, presence of "blind spots," and occasional inadequate imaging of some cardiac structures have necessitated better imaging techniques. Our study aimed to compare the findings of TEE during the initial diagnostic examination with those from intracardiac echocardiography (ICE) acquired during the interventional procedure. METHODS: A total of 65 patients in whom TEE was used for the diagnosis of ASD or PFO were included. Of these, 40 patients (61.5%) had ASD with significant left to right shunt and 25 (38.5%) patients had PFO associated with transient ischemic attack or stroke. ICE imaging was performed under local anesthesia in all patients to guide interatrial communication closure. RESULTS: ICE provided adequate views of the defects and surrounding structures during the various stages of device deployment. In eight patients (12.3%) an additional anatomical variation was detected. All patients had successful device implantation and were discharged 1 day after the procedure. CONCLUSION: ICE is a safe and high-quality imaging technique for guiding transcatheter ASD and PFO occlusion. Additionally, ICE can both facilitate device implantation and detect cardiac abnormalities that are not identified with TEE during the initial diagnostic investigation.

BACKGROUND: Hypertension (HT) is an important risk factor for cardiovascular disease and might precipitate pathology of the aortic valve. OBJECTIVE: To investigate the association of HT with aortic dysfunction (including both aortic regurgitation and stenosis) and the impact of antihypertensive treatment on the natural course of underlying aortic disease. METHODS: We performed a systematic review of the literature for all relevant articles assessing the correlation between HT and phenotype of aortic disease. RESULTS: Co-existence of HT with aortic stenosis and aortic regurgitation is highly prevalent in hypertensive patients and predicts a worse prognosis. Certain antihypertensive agents may improve haemodynamic parameters (aortic jet velocity, aortic regurgitation volume) and remodeling of the left ventricle, but there is no strong evidence of benefit regarding clinical outcomes. Renin-angiotensin system inhibitors, among other vasodilators, are well-tolerated in aortic stenosis. CONCLUSION: Several lines of evidence support a detrimental association between HT and aortic valve disease. Therefore, HT should be promptly treated in aortic valvulopathy. Despite conventional wisdom, specific vasodilators can be used with caution in aortic stenosis.

PURPOSE OF REVIEW: Hypertension consists a major risk factor for cardiovascular events. Despite the proven effectiveness of antihypertensive treatment, approximately half of hypertensive patients have inadequate blood pressure control. Non-adherence to medication has been shown to be an important barrier to achieving adequate blood pressure control and nurse interventions can substantially improve therapeutic compliance. We sought to evaluate the role of nurse interventions in alleviating non-adherence to medication in patients with hypertension by performing a systematic review of the literature for all relevant articles. RECENT FINDINGS: Ten clinical studies were identified. The majority of studies reported beneficial effect of nursing intervention on treatment adherence in hypertensive patients. Telephone contacts and home visits were found to be the most effective educational approaches. Although comorbidities are considered to be an important barrier to adherence, there was not enough evidence to elucidate this aspect. Identifying specific factors that affect behavioral change in the setting of a successful intervention was difficult due to high heterogeneity among studies regarding materials and methods. Nursing interventions were shown to alleviate non-adherence to medication in patients with hypertension. Large well designed clinical trials are needed to evaluate specific factors that are associated with effective interventions.

BACKGROUND: Vulnerable plaque plays crucial role in prognosis of diabetes mellitus (DM). Microwave radiometry (MWR) allows measurement of the temperature of tissues, thus indirectly reflecting inflammation, a characteristic of atherosclerotic plaque stability. Aim of the study was to evaluate the relation of carotid artery inflammation with glycemic control and presence of coronary artery disease (CAD). METHODS: We included 112 patients (65⯱â¯9â¯years, 30⯱â¯5â¯kg/m2, 74 DM and 38 non-DM, with a 2:1 ratio) that were referred for scheduled coronary angiography (CA) for evaluation of their clinical condition. We measured thermal heterogeneity, expressed as temperature difference (ΔT) along each carotid artery, with MWR and maximum temperature difference between the 2 carotid arteries (ΔΤmax). RESULTS: Patients with DM presented higher ΔTmax comparing to patients without DM (0.91⯱â¯0.29 vs 0.71⯱â¯0.25⯰C, pâ¯<â¯0.001). Glycaemia over time was associated with thermal heterogeneity of carotids (HbA1c: <6.5: 0.78⯱â¯0.23, HbA1c: 6.5-7: 0.87⯱â¯0.24, HbA1c: 7-8: 0.99⯱â¯0.30, HbA1c: >8: 1.15⯱â¯0.35⯰C, pâ¯=â¯0.003). Patients with CAD presented higher ΔΤmax comparing to patients with normal CA (0.93⯱â¯0.24 vs 0.68⯱â¯0.25⯰C, pâ¯<â¯0.001) and patients that underwent coronary revascularization presented higher ΔTmax (0.95⯱â¯0.25 vs 0.76⯱â¯0.26⯰C, pâ¯<â¯0.001). A ΔTmaxâ¯≥â¯0.9 (received by ROC analysis) was an independent predictor for revascularization in DM patients (odds ratio 3.29, 95% CI: 1.07-10.16; pâ¯=â¯0.039) when adjusted for sex, age and the established risk factors of CAD. CONCLUSION: Local inflammatory activation of carotid arteries is more pronounced in patients with DM and is associated with the glycemic control. Carotids' thermal heterogeneity is associated with need for revascularization supporting its predictive value in DM patients assessed for CAD.

Patients with rheumatoid arthritis (RA) have higher aortic stiffness and cardiovascular risk. Tumor necrosis factor alpha (TNF-a) antagonists reduce inflammation in RA and are indicated for the treatment of patients with severe active rheumatoid disease. However, it is debatable if they have favorable effects on cardiovascular health. The present meta-analysis evaluates the effect of TNF-a antagonists on aortic stiffness and wave reflections, predictors of cardiovascular events and mortality, in RA patients. A search of PubMed, Cohrane, and Embase databases was conducted to identify studies into the effect of TNF-a antagonists on aortic stiffness in RA patients. Aortic stiffness and wave reflections were assessed by aortic (carotid-femoral [cf]) pulse wave velocity (PWV) and augmentation index (AIx), respectively. cfPWV significantly improved following TNF-a antagonist treatment (mean change: -0.53 m/s, 95% CI: -0.833 to -0.218, p = 0.001), independently of age and clinical response to treatment. A more prominent reduction in cfPWV was associated with etanercept/adalimumab (mean difference: -0.62 m/s, 95% CI: -0.968 to -0.272 m/s, p < 0.001) versus infliximab (mean difference: -0.193 m/s, 95% CI: -0.847 to 0.462 m/s, p = 0.564). TNF-a antagonist treatment induced a significant improvement in AIx (mean change: -1.48%, 95% CI: -2.89 to -0.078%, p = 0.039), but this reduction was influenced by age and clinical response to treatment. The balance of evidence suggests that TNF-a antagonists may have a beneficial effect on aortic stiffness and, therefore, on cardiovascular risk. However, larger, longitudinal studies are warranted to confirm such findings.

BACKGROUND: Current European Guidelines suggest the use of cardiovascular risk categories and also recommend using high-intensity statins for patients with acute coronary syndromes (ACS). OBJECTIVE: We examined the risk of ACS patients prior to the event, as well as the overall use and intensity of statins. METHODS: We enrolled 687 ACS patients (mean age 63 years, 78% males). Low-density lipoprotein cholesterol (LDL-C) levels upon admission were used to assess attainment of LDL-C targets. Patients were categorized as very high, high, moderate and low risk based on their prior to admission cardiovascular (CV) risk. We examined statin use and dosage intensity among patients discharged from the hospital. Patients were followed for a median period of 189 days. RESULTS: The majority of the patients (n=371, 54%) were at very high CV risk prior to admission, while 101 patients were at high risk (15%), 147 (21%) moderate risk and 68 (10%) low risk. Interestingly, LDL-C target attainment decreased as the risk increased (p<0.001). The majority (96%) of patients received statins at discharge; however, most of them (60.4%) received low/moderate intensity statins and just 35.9% received the suggested by the Guidelines high-intensity dose of statins. At follow-up, the rate of patients at high-intensity dose of statins remained similar (34.8%); 6% received no statins at all at follow-up. CONCLUSION: According to our study, the majority of ACS patients are already at high risk prior to their admission. Further, LDL-C targets are underachieved prior to the event and high-intensity statins are underutilized in ACS patients at, and post-discharge.
