Abstract Background/Introduction Hypertension is associated with increased cardiovascular risk, inflammation and arterial stiffness. Purpose We sought to investigate the role of inflammation and arterial stiffness in the prognosis of cardiovascular hospitalizations in hypertensive patients over an extended follow-up. Methods One hundred and seventy-three patients (mean age 52.5±13.2 years, 57% males) untreated hypertensives at baseline without cardiovascular disease, were included in the study. Arterial stiffness was assessed with carotid-femoral pulse wave velocity (PWV). High-sensitivity C-reactive protein (hsCRP) was measured in venous blood samples. Other markers of subclinical organ damage [left ventricular mass index (LVMI) by echocardiography and estimated glomerular filtration rate (eGFR)] were also evaluated in all patients. Results During 13.6±0.4 years of follow-up, forty-four patients (25.4%) patients were admitted in hospital due to cardiovascular causes. In multivariable logistic regression analysis, only higher hsCRP (Odds Ratio [OR] = 3.34, 95% Confidence intervals [CI]: 1.22–9.51, P=0.02) and increased PWV (OR = 1.48, 95% Confidence intervals [CI]: 1.03–2.12, P=0.036) were associated with higher risk of cardiovascular hospitalizations, which was independent of age, gender, systolic blood pressure, LVMI and presence of diabetes. In further analysis, receiver operating characteristic (ROC) curves were generated to evaluate the ability of hsCRP and PWV to discriminate subjects with cardiovascular hospitalization. The area under the curve (AUC) and 95% CIs of the ROC curves were AUC=0.69 (95% CI: 0.59–0.78, p<0.001) for hsCRP and AUC=0.74 (95% CI: 0.65–0.83, P<0.001) for PWV (Figure). Conclusions Our study shows the independent complimentary prognostic role of inflammation and arterial stiffness in the prognosis of hypertensives even in studies with extended follow-up.

Introduction: Diabetes is associated with vascular aging. Arterial stiffness, a marker of vascular aging, is an independent predictor of cardiovascular events and mortality. However, the role of arterial stiffness in the incidence of diabetes has not been investigated. Hypothesis: We sought to investigate the role of carotid-femoral pulse wave velocity (PWV) in the prediction of incident diabetes in hypertensives and hypertensives under treatment with statins. Methods: 376 never-treated hypertensives (mean age 53±13 years, 175 females) without a known history of diabetes or cardiovascular disease at baseline, were included in the study. Markers of target organ damage [carotid-femoral PWV, aortic augmentation index corrected for heart rate (AIx@75) and estimated glomerular filtration rate (eGFR)] were evaluated at baseline in all patients. eGFR was estimated using the Cockcroft-Gault formula. Hemoglobin A1c (HbA1c) and blood glucose were measured in venous blood samples. Patients were followed-up prospectively for the incidence of diabetes as defined by the American Diabetes Association criteria. 139 patients received statins during follow-up. Results: During a median of 13.6 years follow-up, 55 patients (13.4%) patients were diagnosed with diabetes. In multivariable logistic regression analysis, higher PWV (Odds Ratio [OR] = 1.29, 95% Confidence intervals [CI]: 1.02-1.63, P = 0.034) was associated with a higher risk of incident diabetes, which was independent of relevant confounders. In further analysis, receiver operating characteristic (ROC) curves were generated to evaluate the ability of PWV to discriminate subjects with diabetes. The area under the curve (AUC) and 95% CIs of the ROC curve was AUC=0.67 (95% CI: 0.59-0.74, P<0.001) for PWV. In the subgroup of patients under treatment with statins, higher PWV (OR = 1.69, 95% CI: 1.19-2.40, P = 0.004) was also independently associated with a higher risk of incident diabetes. AIx@75 was not associated with the incidence of diabetes. Conclusions: Higher arterial stiffness, a marker of early vascular aging, is associated with the incidence of diabetes and also can identify subjects under treatment with statins that are more likely to present with diabetes in the future.

Abstract Background/Introduction Although arterial stiffening is related to atherosclerosis progression, its prognostic role in hypertension is not fully elucidated, while augmented left ventricular mass index (LVMI) is linked to adverse outcome. Purpose The aim of the present study was to compare the predictive role of changes in arterial stiffness and LVMI for the incidence of coronary artery disease (CAD) in a cohort of essential hypertensive patients. Methods We followed up 1082 essential hypertensives (mean age 55.9 years, 562 males, office blood pressure (BP)=145/91 mmHg) free of cardiovascular disease for a mean period of 8 years. All subjects had at least one annual visit and at baseline and last visit underwent complete echocardiographic study for estimation of LVMI and measurements of arterial stiffness on the basis of carotid to femoral pulse wave velocity (PWV), by means of a computerized method. The distribution of PWV was split by the median (8.2 m/sec) and accordingly subjects were classified into those with high (n=546) and low values (n=536). Moreover, LV hypertrophy (LVH) was defined as LVMI ≥125 g/m2 in males and LVMI ≥110 g/m2 in females, while CAD was defined as the history of myocardial infarction or significant coronary artery stenosis revealed by angiography or coronary revascularization procedure. Results The incidence of CAD over the follow-up period was 3.5%. Hypertensives who developed CAD (n=38) compared to those without CAD at follow-up (n=1044) had at baseline higher waist circumference (101.7±10.1 vs 96.2±11.6 cm, p=0.004), LVMI (123.9±22.1 vs 105.8±21.3 g/m2, p=0.026), prevalence of LVH (46% vs 25%, p=0.018) and prevalence of high PWV levels (67% vs 40%, p=0.021). No difference was observed between hypertensives with CAD and those without CAD with respect to baseline office BP, serum creatinine and lipid levels (p=NS for all). By univariate Cox regression analysis, it was revealed that changes in PWV levels between baseline and last visit predicted CAD (hazard ratio=1.243, p=0.014). However, in multivariate Cox regression model baseline glomerular filtration rate (hazard ratio=1.029, p=0.015) and changes in LVMI (hazard ratio=1.036, p<0.0001) but not alterations of PWV turned out to be independent predictors of CAD. Conclusions In essential hypertensive patients changes in LVMI predict future development of CAD, whereas PWV alterations exhibit no independent prognostic value. These findings support that LVMI constitutes a superior prognosticator of events than PWV and its estimation is essential in order to improve overall risk stratification in hypertension.

AbstractThis study aimed to assess the role of multifocal visual-evoked potentials (mfVEPs) as a guiding factor for clinical conversion of radiologically isolated syndrome (RIS). We longitudinally followed a cohort of 15 patients diagnosed with RIS. All subjects underwent thorough ophthalmological, neurological and imaging examinations. The mfVEP signals were analysed to obtain features in the time domain (SNRmin: amplitude, Latmax: monocular latency) and in the continuous wavelet transform (CWT) domain (bmax: instant in which the CWT function maximum appears, Nmax: number of CWT function maximums). The best features were used as inputs to a RUSBoost boosting-based sampling algorithm to improve the mfVEP diagnostic performance. Five of the 15 patients developed an objective clinical symptom consistent with an inflammatory demyelinating central nervous system syndrome during follow-up (mean time: 13.40 months). The (SNRmin) variable decreased significantly in the group that converted (2.74 ± 0.92 vs. 4.07 ± 0.95, p = 0.01). Similarly, the (bmax) feature increased significantly in RIS patients who converted (169.44 ± 24.81 vs. 139.03 ± 11.95 (ms), p = 0.02). The area under the curve analysis produced SNRmin and bmax values of 0.92 and 0.88, respectively. These results provide a set of new mfVEP features that can be potentially useful for predicting prognosis in RIS patients.

Abstract Background The aetiology of recent-onset dilated cardiomyopathy (RODCM) includes inflammatory, genetic, toxic and metabolic causes. Delineating the role of inflammation on the genetic background could improve risk stratification. Purpose We aimed to ascertain the role of inflammation evaluated by serum CRP immunohistochemical and PCR analysis of endomyocardial biopsy (EMB) in conjunction with genetic testing in left ventricular reverse remodelling (LVRR) in 12-month follow-up. Methods 83 RODCM patients enrolled in this prospective observational study underwent 12-month echocardiographic follow up whole-exome sequencing, and EMB. Presence of cardiotropic viruses was determined by PCR analysis of the EMB samples. Inflammation was defined according to TIMIC immunohistochemical criteria as the presence of &gt;7 CD3+ lymphocytes/mm2 and/or &gt;14 infiltrating leukocytes (LCA+ cells/mm2). LVRR was defined as an absolute increase in LV ejection fraction &gt; +10% and a relative decrease of LV end-diastolic diameter &gt;−10% at 12 months. Results LVRR occurred in 28 (34%) of all cases. PCR analysis uncovered cardiotropic viruses in 55 (66%) patients, with highest prevalence of parvovirus B19 (47%). (Figure 1) EMB analysis detected inflammation in 28 (34%) cases and inflammation significantly positively predicted LVRR (P=0.019). Sequencing identified disease-related gene variants (ACMG class 3–5) in 45 (54%) patients. Carriers of non-titin gene variants showed a lowest probability of 12-month LVRR (19%) P=0.041. Combination of genetic findings and inflammation did not improve the prediction of LVRR in 12 months. (Table 1) Conclusion Both myocardial inflammation and disease-causing variants can be identified in a large proportion of RODCM cases. Prognostic value of CRP and virus detection is low. Non-titin disease-related variants carriers of are less likely to reach LVRR. In contrast, myocardial inflammation detected by EMB predicts favourable remodelling in 12 months.

Introduction: Active surveillance (AS) is standard of care in low-risk prostate cancer (PC). This study describes a novel total cancer location (TCLo) density metric and aims to determine its performance in predicting clinical progression (CP) and grade progression (GP).     Methods: This was a retrospective study of patients on AS after confirmatory biopsy (CBx). We excluded patients with Gleason ≥7 at CBx and <2 years follow-up. TCLo was the number of locations with positive cores at diagnosis (DBx) and CBx. TCLo density was TCLo / prostate volume (PV). CP was progression to any active treatment while GP occurred if Gleason ≥7 was identified on repeat biopsy or surgical pathology. Independent predictors of time to CP or GP were estimated with Cox regression. Kaplan-Meier analysis compared progression-free survival curves between TCLo density groups. Test characteristics of TCLo were explored with receiver operating characteristic (ROC) curves.     Results: We included 181 patients who had CBx between 2012-2015, and met inclusion criteria. The mean age of patients was 62.58 years (SD=7.13) and median follow-up was 60.9 months (IQR=23.4). A high TCLo density score (>0.05) was independently associated with time to CP (HR 4.70, 95% CI: 2.62-8.42, p<0.001), and GP (HR 3.85, 95% CI: 1.91-7.73, p<0.001). ROC curves showed TCLo density has greater area under the curve than number of positive cores at CBx in predicting progression.     Conclusion: TCLo density is able to stratify patients on AS for risk of CP and GP. With further validation, it could be added to the decision-making algorithm in AS for low-risk localized PC.

Introduction: Ablation of ventricular tachycardia (VT) substrate in patient at risk for VT in the setting of ischemic heart disease is a technically challenging procedure. We thought to evaluate a novel algorithm used to automatically identify target electrograms. Methods: 16 consecutive patients (70±10 years of age, 90% male, 34±18% LV EF) had 20 ablations for ischemic VT using CARTO 3 mapping system over 2 years. Left ventricular (LV) substrate was mapped during right ventricular (RV) apical stimulation. Navistar Thermocool 3.5 mm irrigated tip catheters were used in all patients. A novel algorithm counting the number of electrogram deflections (NOD) crossing the 0.05mV noise threshold and duration of time from first to last such deflection during the window of interest (total fractionation time, TFT) was applied to all acquired maps after ablation was complete. Snapshots of 200 electrograms representing the high and low end of TFT and NOD values were presented to a group of 8 electrophysiologists experienced in VT ablation who were asked to select electrograms they would target for substrate ablation. The diagnostic accuracy of TFT and NOD values was then analysed. Results: Across the range of TFT values (0.0-281.0 ms), a cut-off value of 49.0 ms (81.6% sensitivity, 57% specificity) was established as an optimal indicator of an ablation target. Area under the curve for TFT was 0.675 (95% CI: 0.59-0.75, p=0.001). For NOD values (0.0-70.0 deflections), a cut off of 4.5 deflections (88.0% Sensitivity, 57 % specificity) was established as an optimal indicator of an ablation target. The area under the curve for NOD yielded an area of 0.75 (95% CI: 0.68-0.82, P=0.001). For TFT-NOD product as a variable, a cut-off value of 64 (91.0% Sensitivity, 52.4 % specificity) an optimal indicator of an ablation target. The Area under the curve for NOD and TFT multiple was 0.72 (95% CI: 0.65-0.80, P=0.001). Conclusion: A novel algorithm may be able to automatically classify LV substrate during mapping and ablation of ischemic VT with high sensitivity and acceptable specificity.

Life expectancy in patients affected by cancer has recently increased because of early diagnosis and actual therapies. In recent years, Oncology and Cardiology developed a tight relationship because of common risk factors (i.e. obesity, smoking, alcool intake, etc…), and for preventing the prothrombotic status due to cancer and the potential cardiotoxicity of chemotherapy. Cardiotoxicity incidence is reported from 1% up to 70% in retrospective analyses of drug protocols, mainly representing by left ventricular dysfunction (both reversible or irreversible), but also by arrhythmias, hypertension, atrioventricular block, coronary spasm, and arterial or venous thromboembolism. The early detection of the chemoterapy induced cardiotoxicity is now mandatory and can be obtained through a proper patients selection for different treatments and a strict monitoring during the follow-up period. The role of biomarkers of early cardiac damage, mainly, troponin I and brain natriuretic peptide-BNP, has been recently challenged, and algorithms are currently available. In the present paper, we propose how to perform a cardiological evaluation of patients undergoing chemoterapy tailored by the known adverse effects of the drugs.

Cardiac imaging techniques have an important role in the follow-up of patients undergoing cardiac resynchronization therapy (CRT) as they provide objective evidence of changes in cardiac dimensions and function. The role of echocardiography is well established in the assessment of left ventricular reverse remodelling and the evaluation of secondary (functional) mitral regurgitation. Additionally, echocardiography might be used for optimizing the programming of atrio-ventricular (AV) and inter-ventricular (VV) delays of current CRT devices. Acute benefits from this optimization have been demonstrated, but longer follow-up studies have failed to show a clear benefit of optimized CRT on top of simultaneous biventricular pacing on the outcome of patients with CRT. This chapter reviews the role of imaging in assessing follow-up and outcome of patients undergoing CRT, as well as the rationale, the methods used, and the clinical impact of optimization of the programming of CRT devices.

Aim: To explore whether elevated serum sortilin was associated with calcified carotid plaque and ischemic stroke. Methods: A total of 171 patients with cardiovascular risk factors were enrolled. Ultrasonography was performed to evaluate calcified plaques and noncalcified plaques. Serum sortilin concentration was measured by ELISA. Results: Serum sortilin level was higher in patients with calcified carotid plaque and positively related to carotid plaque burden, but not with ischemic stroke during the follow-up. Multivariable logistic regression analysis revealed serum sortilin level was an independent determinant for calcified carotid plaque (p = 0.001). Receiving operating characteristic analysis showed an area under the curve of sortilin for carotid calcification was 0.759. Conclusion: Higher serum sortilin level was associated with carotid calcification and severe carotid plaque score.
