Cardiac amyloidosis is the most frequent infiltrative disease caused by the deposition of misfolded proteins in the cardiac tissue, leading to heart failure, brady- and tachyarrhythmia and death. Conduction disorders, atrial fibrillation (AF) and ventricular arrhythmia (VA) significantly impact patient outcomes and demand recognition. However, several issues remain unresolved regarding early diagnosis and optimal management. Extreme bradycardia is the most common cause of arrhythmic death, while fast and sustained VAs can be found even in the early phases of the disease. Risk stratification and the prevention of sudden cardiac death are therefore to be considered in these patients, although the time for defibrillator implantation is still a subject of debate. Moreover, atrial impairment due to amyloid fibrils is associated with an increased risk of AF resistant to antiarrhythmic therapy, as well as recurrent thromboembolic events despite adequate anticoagulation. In the last few years, the aging of the population and progressive improvements in imaging methods have led to increases in the diagnosis of cardiac amyloidosis. Novel therapies have been developed to improve patients’ functional status, quality of life and mortality, without data regarding their effect on arrhythmia prevention. In this review, we consider the latest evidence regarding the arrhythmic risk stratification of cardiac amyloidosis, as well as the available therapeutic strategies.

Over the past decade, remote monitoring (RM) has become an increasingly popular way to improve healthcare and health outcomes. Modern cardiac implantable electronic devices (CIEDs) are capable of recording an increasing amount of data related to CIED function, arrhythmias, physiological status and hemodynamic parameters, providing in-depth and updated information on patient cardiovascular function. The extensive use of RM for patients with CIED allows for early diagnosis and rapid assessment of relevant issues, both clinical and technical, as well as replacing outpatient follow-up improving overall management without compromise safety. This approach is recommended by current guidelines for all eligible patients affected by different chronic cardiac conditions including either brady- and tachy-arrhythmias and heart failure. Beyond to clinical advantages, RM has demonstrated cost-effectiveness and is associated with elevated levels of patient satisfaction. Future perspectives include improving security, interoperability and diagnostic power as well as to engage patients with digital health technology. This review aims to update existing data concerning clinical outcomes in patients managed with RM in the wide spectrum of cardiac arrhythmias and Hear Failure (HF), disclosing also about safety, effectiveness, patient satisfaction and cost-saving.

Fluoroscopy has always been the cornerstone imaging method of interventional cardiology procedures. However, radiation exposure is linked to an increased risk of malignancies and multiorgan diseases. The medical team is even more exposed to X-rays, and a higher incidence of malignancies was reported in this professional group. In the last years, X-ray exposure has increased rapidly, involving, above all, the medical team and young patients and forcing alternative fluoroless imaging methods. In cardiac electrophysiology (EP) and pacing, the advent of 3D electroanatomic mapping systems with dedicated catheters has allowed real-time, high-density reconstruction of both heart anatomy and electrical activity, significantly reducing the use of fluoroscopy. In addition, the diffusion of intracardiac echocardiography has provided high anatomical resolution of moving cardiac structures, providing intraprocedural guidance for more complex catheter ablation procedures. These methods have largely demonstrated safety and effectiveness, allowing for a dramatic reduction in X-ray delivery in most arrhythmias’ ablations. However, some technical concerns, as well as higher costs, currently do not allow their spread out in EP labs and limit their use to only procedures that are considered highly complex and time-consuming and in young patients. In this review, we aim to update the current employment of fluoroless imaging in different EP procedures, focusing on its strengths and weaknesses.

Abstract Aims The angiotensin receptor–neprilysin inhibitor (ARNI), sacubitril/valsartan, has been shown to be effective in treatment of patients with heart failure (HF), but limited data are available in patients with advanced disease. This retrospective observational study assessed the effects of ARNI treatment in patients with advanced HF. Methods and results We reviewed medical records of all advanced HF patients evaluated at our centre for unconventional therapies from September 2016 to January 2019. We studied 44 patients who started ARNI therapy and who had a haemodynamic assessment before beginning ARNI and after 6 ± 2 months. The primary endpoint was variation in pulmonary pressures and filling pressures at 6 months after starting ARNI therapy. Mean patient age was 51.6 ± 7.4 years; 84% were male. At 6 ± 2 months after starting ARNI, there was significant reduction of systolic pulmonary artery pressure [32 mmHg, interquartile range (IQR) 27–45 vs. 25 mmHg, IQR 22.3–36.5; P

Intraprocedural stroke is a well-documented and feared potential risk of cardiovascular transcatheter procedures (TPs). Moreover, subclinical neurological events or covert central nervous system infarctions are concerns related to the development of dementia, future stroke, cognitive decline, and increased risk of mortality. Cerebral protection devices (CPDs) were developed to mitigate the risk of cardioembolic embolism during TPs. They are mechanical barriers designed to cover the ostium of the supra-aortic branches in the aortic arch, but newer devices are able to protect the descending aorta. CPDs have been mainly designed and tested to provide cerebral protection during transcatheter aortic valve replacement (TAVR), but their use in both Catheterization and Electrophysiology laboratories is rapidly increasing. CPDs have allowed us to perform procedures that were previously contraindicated due to high thromboembolic risk, such as in cases of intracardiac thrombosis identified at preprocedural assessment. However, several concerns related to their employment have to be defined. The selection of patients at high risk of thromboembolism is still a subjective choice of each center. The aim of this review is to update the evidence on the use of CPDs in either Cath labs or EP labs, providing an overview of their structural characteristics. Future perspectives focusing on their possible future employment are also discussed.

The difference between subcutaneous implantable cardioverter defibrillators (S-ICDs) and transvenous ICDs (TV-ICDs) concerns a whole extra thoracic implantation, including a defibrillator coil and pulse generator, without endovascular components. The improved safety profile has allowed the S-ICD to be rapidly taken up, especially among younger patients. Reports of its role in different cardiac diseases at high risk of SCD such as hypertrophic and arrhythmic cardiomyopathies, as well as channelopathies, is increasing. S-ICDs show comparable efficacy, reliability, and safety outcomes compared to TV-ICD. However, some technical issues (i.e., the inability to perform anti-bradycardia pacing) strongly limit the employment of S-ICDs. Therefore, it still remains only an alternative to the traditional ICD thus far. This review aims to provide a contemporary overview of the role of S-ICDs compared to TV-ICDs in clinical practice, including technical aspects regarding device manufacture and implantation techniques. Newer outlooks and future perspectives of S-ICDs are also brought up to date.

Endothelial dysfunction (ED) is frequently found in patients with heart failure (HF). Among several pharmacological agents reported to improve endothelial function, levosimendan seems to be a promising one, even though, to date, only two previously published studies have evaluated its effects on ED in these patients. The aim of our pilot study was to further investigate the role of periodic levosimendan infusion on endothelial function in patients affected by advanced HF. In this cross-sectional study, three different groups were enrolled: 20 patients with advanced HF treated with periodic levosimendan (LEVO), 20 patients with HF on optimal medical therapy (OMT), and 20 healthy subjects (control group). ED was evaluated through flow-mediated dilation (FMD) at the level of the brachial artery. The three groups presented similar ages with significant differences in gender distribution, systolic blood pressure, and chronic kidney disease (eGFR < 30 mL/min). In HF patients, ischaemic aetiology was more prevalent in the LEVO group than in the OMT group (60 vs. 40%, p < 0.001). The New York Heart Association (NYHA) functional class was worse in the LEVO group, as well as in NT-proBNP (5636.7 ± 6164.6 ng/dL and 1243.7 ± 1487.2 ng/dL, in the LEVO and OMT groups, respectively, p = 0.005). The FMD was significantly higher in the healthy control group compared to that of the OMT group (15.7 ± 6.4 vs. 9.1 ± 6.0%, p = 0.007) while it showed an intermediate value in LEVO patients (12.4 ± 7.1%) (ANOVA p = 0.010). In conclusion, levosimendan therapy seems to ameliorate endothelial dysfunction related to heart failure. Longitudinal studies in patients on periodic therapy are needed in order to confirm the long-term effects of levosimendan on ED.

Diseases of the circulatory (Cardiovascular) system ,RC666-701 - Abstract
Platelets play a key role in the pathogenesis of ventricular assist device (VAD) thrombosis; therefore, antiplatelet drugs are essential, both in the acute phase and in the long-term follow-up in VAD management. Aspirin is the most used agent and still remains the first-choice drug for lifelong administration after VAD implantation. Anticoagulant drugs are usually recommended, but with a wide range of efficacy targets. Dual antiplatelet therapy, targeting more than one pathway of platelet activation, has been used for patients developing a thrombotic event, despite an increased risk of bleeding complications. Although different strategies have been attempted, bleeding and thrombotic events remain frequent and there are no uniform strategies adopted for pharmacological management in the short and mid- or long-term follow up. The aim of this article is to provide an overview of the evidence from randomized clinical trials and observational studies with a focus on the pathophysiologic mechanisms underlying bleeding and thrombosis in VAD patients and the best antithrombotic regimens available.

Objective: The role of risk factors on the progression of arterial stiffness has not yet been extensively evaluated. The aim of the current longitudinal study was to evaluate the determinants of the PWV progression over a 4 years follow-up period in hypertensive subjects. Materials and Methods: We enrolled 333 consecutive hypertensive outpatients 18–80 aged, followed by the Hypertension Unit of St. Gerardo Hospital (Monza, Italy). At baseline anamnestic, clinical, BP, laboratory data and cfPWV were assessed. We performed a PWV follow-up examination with a median time amounting to 3.75 ± 0.53 years. Results: At baseline the mean age was 54.5 ± 12.6 years, SBP and DBP were 141.3 ± 18.6 and 86.4 ± 10.4 mmHg and PWV was 8.56 ± 1.92 m/s. Despite an improvement in BP control (from 37 to 60%), at follow-up the population showed a PWV increase (ΔPWV 0.87 ± 3.05 m/s). PWV and ΔPWV gradually increased in age decades. In patients with uncontrolled BP values at follow-up ΔPWV showed a greater increase as compared to patients with controlled BP (1.46 ± 3.67 vs 0.62 ± 2.61 m/s, p

Background: To date no definitive results exist about the relationship of Serum Uric Acid (SUA) and TOD in HT subjects. We sought to determine if such an association exist between SUA and subclinical cardiac, vascular and renal alterations in HT. Methods: We enrolled 632 consecutive outpatients, followed by the Hypertension Unit of S. Gerardo Hospital (Monza, Italy) affected by essential HT. We evaluated anamnestic data, clinical BP and laboratory data as well as TOD with cardiac echocardiography (both as LMVI and diastolic function – E/A), carotid ultrasound (IMT), arterial stiffness (PWV) and renal function analysis (creatinine and microalbumiuria). Results: Age was 53.4±12.7 years, SBP/DBP were 140.5±18.8 and 85.1±13.1 mmHg and SUA was 5.2±1.4 mg/dL. Regarding TOD mean LVMI was 109.6±31.4g/m2, IMT 0.71±0.1 mm, PWV 8.5±2.2 m/s, while creatinine and microalbuminuria were 0.8±0.2 mg/dL and 25.4±126.1 mg/24h respectively. When subjects were divided into high and low SUA group (depending on the median SUA of 5.2 mg/dL), with similar age and BP values the first group showed significantly higher values of metabolic index (BMI, HDL chol, triglycerides and glucose, p < 0.001), LVMI (117.1±32.8 vs 102.1±28.1g/m2, p < 0.01), IMT (0.73±0.1 vs 0.70±0.1mm, p = 0.04), PWV (8.8±2.4 vs 8.3±2.1m/s, p = 0.01) and creatinine (0.9±0.2 vs 0.7±0.1 mg/dL, p < 0.01) and lower E/A (1,0±0.3 vs 1.1±0.3, p < 0.01). SUA showed significant correlation with sex, age, BMI, SBP, HDL chol, triglicerides, glucose, creatinine, IMT, LVMI and E/A. Regarding TOD only creatinine presents SUA as as significant determinant in logistic regression analysis. Conclusion: In HT, SUA values correlate with metabolic derangements and with cardiac, vascular and renal TOD. The most significant correlation is with renal damage.

Objective: Prior studies have suggested that the principal determinants of arterial stiffening are age, BP and others CV risk factors such as dyslipidemia and diabetes. However, scanty data are available on the role of psychological factors on arterial stiffness. The aim of the current cross-sectional study was to evaluate the association between depression, anxiety, perceived stress, Type A personality, and Type D personality and Pulse Wave Velocity (PWV) in a cohort of hypertensive patients, using baseline examination data of the TIPICO project. Methods: A total of 259 outpatients (ages 18–80 years) followed by the Hypertension Unit of S. Gerardo Hospital (Monza, Italy) affected by essential hypertension were recruited. Aortic stiffness was evaluated by c-f PWV. Moreover, anamnestic data, clinical BP, and laboratory data were evaluated. Patients were asked to complete a battery of psychological questionnaires under the guidance of a psychologist. Results: At T0 mean age was 55.9±10.1years, SBP/DBP were 135.6±17.7/82.5±9.1 mmHg and PWV was 8.6±2.1m/s. The multivariate stepwise linear regression analysis showed that age (beta = 0.284, p < 0.001), pulse pressure (beta = 0.369, p < 0.001), dyslipidemia (beta = 0.130, p = 0.012), family history of CV disease (beta = −0.123, p = 0.017), and depression (beta = 0.126, p = 0.014) were significantly and independently associated with PWV. Conclusion: Among psychological factors, higher levels of depression is related to higher PWV, while anxiety, perceived stress, Type-A personality and Type-D personality are not. Depression assessment and target intervention to reduce it should be recommended in hypertensive patients.

Objective: Thoracic Endovascular Aortic Repair (TEVAR) currently represents the gold standard of treatment for Blunt Thoracic Aortic Injury (BTAI). Nevertheless, there is an ongoing debate surrounding its safety and efficacy and its subsequent CV effects. The present study is aimed at assessing heart and aortic structure and function after TEVAR in BTAI patients Method: In 20 patients (18 men, age 41 ± 14 years) treated with TEVAR (11 Gore-CTAG, 9 Medtronic-Valiant) after BTAI, between 2004–2015, after a median follow-up time of 3 years (range 12–1 years; T1) we evaluated BP, cf-PWV (sphygmocor) and Left Ventricular Mass Index (LVMI) on echocardiography. Results: At baseline, all the patients were normotensive; At T1 despite mean normal BP value (131 ± 12/85 ± 10) 11 patients (55%) were hypertensives. Also LVMI (81,84 ± 28,11 g/m2) and PWV (7,58 ± 1,48 m/s) mean values were within the normal range. When patients were divided accordingly to the used graft patients treated with Medtronic-Valiant showed a significantly higher LVMI (97.17 ± 35.78 vs 69.58 ± 11.24 g/m2; p < 0,05) and PWV (7,78 ± 1,74 vs 6,45 ± 1,54 m/s; p < 0,05) compared with those treated with Gore-CTAG. Same figures were founded when patients were divided accordingly to the treating time with those treated more than 3 years before the evaluation that showed higher LVMI (91,16 ± 34,73 vs 70,20 ± 9,44 g/m2; p < 0,01) and PWV (7,50 ± 1,98 vs 6,38 ± 1,04 m/s; p < 0,05). Conclusions: TEVAR for BTAI is associated after some years with the development of hypertension and heart and vascular alterations. The presence of TEVAR modify aortic functional properties and induce in young subject an increase in BP and LVMI probably related to the presence of a rigid aorta.

Pheochromocytoma is a tumor arising from neuroectodermal chromaffin tissues in the adrenal gland or extra-adrenal paraganglia (paragangliomas). The prevalence of the tumor is 0.1%-0.6% in the hypertensive population, of which 10%-20% are malignant. Pheochromocytoma produces, stores, and secretes catecholamines, as well as leads to hypertensive crisis, arrhythmia, angina, and acute myocardial infarction without coronary artery diseases. We report a case of acute coronary syndrome (ACS) with a final diagnosis of multiple endocrine neoplasia with pheochromocytoma and medullary thyroid carcinoma (MTC).

ECG ,epilepsy ,Brugada Syndrome ,cardiac channelopathies ,sudden cardiac death ,sudden unexpected death in epilepsy - Abstract
Background: The brain and heart are strictly linked and the electrical physiologies of these organs share common pathways and genes. Epilepsy patients have a higher prevalence of electrocardiogram (ECG) abnormalities compared to healthy people. Furthermore, the relationship between epilepsy, genetic arrhythmic diseases and sudden death is well known. The association between epilepsy and myocardial channelopathies, although already proposed, has not yet been fully demonstrated. The aim of this prospective observational study is to assess the role of the ECG after a seizure. Materials and Methods: From September 2018 to August 2019, all patients admitted to the emergency department of San Raffaele Hospital with a seizure were enrolled in the study; for each patient, neurological, cardiological and ECG data were collected. The ECG was performed at the time of the admission (post-ictal ECG) and 48 h later (basal ECG) and analyzed by two blinded expert cardiologists looking for abnormalities known to indicate channelopathies or arrhythmic cardiomyopathies. In all patients with abnormal post-ictal ECG, next generation sequencing (NGS) analysis was performed. Results: One hundred and seventeen patients were enrolled (females: 45, median age: 48 ± 12 years). There were 52 abnormal post-ictal ECGs and 28 abnormal basal ECGs. All patients with an abnormal basal ECG also had an abnormal post-ictal ECG. In abnormal post-ictal ECG, a Brugada ECG pattern (BEP) was found in eight patients (of which two had BEP type I) and confirmed in two basal ECGs (of which zero had BEP type I). An abnormal QTc interval was identified in 20 patients (17%), an early repolarization pattern was found in 4 patients (3%) and right precordial abnormalities were found in 5 patients (4%). Any kind modification of post-ictal ECG was significantly more pronounced in comparison with an ECG recorded far from the seizure (p = 0.003). A 10:1 higher prevalence of a BEP of any type (particularly in post-ictal ECG, p = 0.04) was found in our population compared to general population. In three patients with post-ictal ECG alterations diagnostic for myocardial channelopathy (BrS and ERP), not confirmed at basal ECG, a pathogenic gene variant was identified (KCNJ8, PKP2 and TRMP4). Conclusion: The 12-lead ECG after an epileptic seizure may show disease-related alterations otherwise concealed in a population at a higher incidence of sudden death and channelopathies. Post-ictal BEP incidence was higher in cases of nocturnal seizure.

Background and aims: Interest in the role of atrial substrate in maintaining Atrial Fibrillation (AF) is growing. Fibrosis is the culprit in the electrical derangement of the myocytes. Many cardiovascular risk factors are known to be linked to atrial scarring; among them Uric Acid (UA) is emerging. The purpose of our study is to find whether UA is associated with Left Atrium (LA) with pathological substrate. Methods and results: 81 patients who underwent radiofrequency transcatheter ablation for nonvalvular AF at the cardiological department of the Niguarda Hospital were enrolled in an observational, cross-sectional, single-center study. UA levels were analysed before the procedure.

Cardiology and Cardiovascular Medicine - Abstract
Background Identifying markers associated with adverse events after acute myocarditis (AM) is clinically relevant to plan follow-up. We aimed to compare the prognostic performance of previously described cardiac magnetic resonance imaging (CMRI) markers: septal late gadolinium enhancement (LGE) localization and left ventricular ejection fraction (LVEF) Methods We retrospectively assessed 248 AM patients from 6 hospitals with onset of cardiac symptoms Results Patients had a median age of 34 years (male prevalence of 87.1%) and a median LVEF of 61% on baseline CMRI. Thirteen patients (5.2%) experienced at least one major cardiac event after a median follow-up of 1708 days. Among these 13 patients, 10 (76.9%) had septal LGE, 8 (61.5%) had LVEF Conclusions Major cardiac events after an AM are relatively low, and septal LGE, LVEF Figure A] Acute Myocarditis with complicated clinical presentation (CCP AM) vs non-complicated clinical presentation (NO CCP AM); B] FE > 50% vs FE < 50% at basal cardiac MRI; C] Presence of septal late gadolinium enhancemnet (LGE) vs no septal LGE on basal cardiac MRI.

BACKGROUND Fulminant myocarditis (FM) is a form of acute myocarditis characterized by severe left ventricular systolic dysfunction requiring inotropes and/or mechanical circulatory support. A single-center study found that a patient with FM had better outcomes than those with acute nonfulminant myocarditis (NFM) presenting with left ventricular systolic dysfunction, but otherwise hemodynamically stable. This was recently challenged, so disagreement still exists. OBJECTIVES This study sought to provide additional evidence on the outcome of FM and to ascertain whether patient stratification based on the main histologic subtypes can provide additional prognostic information. METHODS A total of 220 patients (median age 42 years, 46.3% female) with histologically proven acute myocarditis (onset of symptoms

Background Pregnancy after heart transplantation (HTx) may expose the recipient to hemodynamic and immunologic risks and the newborn to toxic effects of immunosuppressive therapy. Adequate preconception counseling is crucial to identify optimal timing and to modify immunosuppressive therapy to minimize risks for both the mother and the fetus. Methods We describe our experience with 12 pregnancies occurred in 11 women who had undergone HTx at our center. Results Pregnancies ran without severe complications or rejections, and none of the babies have shown major defects at birth. However, as reported in the literature, weight at birth rated in lower range in most of the newborns, probably due to in utero cyclosporine exposure. Up to now, none of the babies showed clinical signs of heart disease, although more than half of the mothers had an inherited or familial cardiomyopathy. Conclusions Despite potential mother and fetal complications, successful pregnancy and delivery are possible after HTx, provided that optimum timing, close monitoring, and therapy adjustments are guaranteed. Becoming a mother appears to be an important achievement for young women after HTx, even when there is a risk to transmit an inheritable heart disease.

Introduction Endothelial Dysfunction (ED) of peripheral arteries in Chronic Heart Failure (CHF) subjects has been demonstrated. Purpose We assessed endothelial function in subjects undergoing unconventional treatments for CHF, namely Heart Transplantation (HTX), continuous-flow Left Ventricular Assist Device implantation (LVAD), and repeated levosimendan infusions (r-LEVO). Methods Twenty HTX recipients (median time from HTX 21 months), 20 patients supported with LVAD (median time from implant 39 months), and 20 patients receiving monthly Levosimendan infusions (median time on treatment 28 months) were enrolled and compared to a group of 20 healthy subjects. ED was evaluated with ultrasound assessment of the diameter before and after ischemic stress at the brachial artery level. The difference between the two diameters normalized for the baseline value (Flow Mediated Dilation – FMD) has been used for the analysis. All the patients were stable at the time of FMD assessment, with those on r-LEVO being evaluated prior to infusion. Results FMD was significantly lower in HTX and LVAD groups with respect to controls (9.8±7.4, 9.3±5.7, and 15.6±6.4% respectively, p=0.01), but not in r-LEVO group (12.5±6.9%). When patients were analyzed according to time from the operation or on treatment, (< versus > of the median value), no differences were seen in HTX and r-LEVO group, while in LVAD group FMD was borderline significantly higher in patients with longer follow-up (8.4±6.4% versus 10.2±5.2%, p=0.05). Conclusions Based on this preliminary data we can inference the following: 1- FMD is abnormal in HTX recipients, despite their good functional status, probably due to factors unrelated to CHF (e.g. hypertension, renal insufficiency, denervation, and drug effects); 2- LVAD patients also show ED, with possible better adaptation in very long-term survivors; 3- Near-normal FMD values in CHF patients who remain stable with r-LEVO suggest that pulsed treatment may obtain favorable effects at peripheral level, persisting after clearance of the drug and its metabolites.

Objective— Aim of this study was to evaluate changes in LCAT (lecithin:cholesterol acyltransferase) concentration and activity in patients with an acute coronary syndrome, to investigate if these changes are related to the compromised capacity of HDL (high-density lipoprotein) to promote endothelial nitric oxide (NO) production, and to assess if rhLCAT (recombinant human LCAT) can rescue the defective vasoprotective HDL function. Approach and Results— Thirty ST-segment–elevation myocardial infarction (STEMI) patients were enrolled, and plasma was collected at hospital admission, 48 and 72 hours thereafter, at hospital discharge, and at 30-day follow-up. Plasma LCAT concentration and activity were measured and related to the capacity of HDL to promote NO production in cultured endothelial cells. In vitro studies were performed in which STEMI patients’ plasma was added with rhLCAT and HDL vasoprotective activity assessed by measuring NO production in endothelial cells. The plasma concentration of the LCAT enzyme significantly decreases during STEMI with a parallel significant reduction in LCAT activity. HDL isolated from STEMI patients progressively lose the capacity to promote NO production by endothelial cells, and the reduction is related to decreased LCAT concentration. In vitro incubation of STEMI patients’ plasma with rhLCAT restores HDL ability to promote endothelial NO production, possibly related to significant modification in HDL phospholipid classes. Conclusions— Impairment of cholesterol esterification may be a major factor in the HDL dysfunction observed during acute coronary syndrome. rhLCAT is able to restore HDL-mediated NO production in vitro, suggesting LCAT as potential therapeutic target for restoring HDL functionality in acute coronary syndrome.

Background Thoracic endovascular aortic repair (TEVAR) currently represents the gold standard of treatment for thoracic aortic injury (TAI). Nevertheless, there is an ongoing debate surrounding its safety and subsequent cardiovascular effects. Our aim is to assess heart and vascular structure and function remodeling after TEVAR in TAI young patients. Methods We evaluated 20 patients (18 men, age 41 ± 14 years, 11 treated with Gore CTAG, 9 with Medtronic Valiant) with office and 24-hr blood pressure (BP) with specific vascular stiffness analysis (Mobil-O-Graph), aortic diameters (computed tomography scan) and left ventricular mass index (LVMI echocardiogram). Evaluation was done after a median time of 5.0 ± 3.5 years from the trauma. Results After TAI 12 patients (55%) developed hypertension. When patients were divided according to treating time, those treated for more than 3 years show higher LVMI, PWV, and ascending aorta dilatation. Conclusions Our study shows that TEVAR for TAI is associated with heart and vascular remodeling. The presence of TEVAR modifies aortic functional properties and could induce an increase in BP that can promote aortic and cardiac damage, even in young patients.

Purpose Candidate selection and donor allocation should promote equitable access to heart transplantation (HTX) according to patients’ needs, avoiding HTX in patients (pts) who are too well or too sick to get benefit. The national HTX database was analyzed to identify which variables were related to the competing events of getting HTX or dying on the waiting list (WL), and to post-transplant survival. Methods Pts aged 14 years or more, who were listed for primary HTX from May 2012 and December 2016, were followed until January 2018, death or delisting for worsening. The incidence of death on the WL or of HTX were analyzed according to Aalen-Johansen method. Post-HTX survival was evaluated with Kaplan-Meyer method. Univariate and multivariate cause-specific Cox proportional hazard model was used to identify candidates’ variables related to access to HTX or death on the WL, and preoperative recipients’ variables related to post-HTX mortality. Results Of 1611 listed pts (males 78%, median age 54 y), 10% died and 45% received HTX within 1 year. At the end of follow-up 932 pts (males 73%, median age 53y) had undergone HTX: 13% were bridged with LVAD, 17% were on short-term mechanical circulatory support (MCS), 28% received HTX with emergency heart allocation, and 42% were medically treated outpatients. One-, 3- and 5-years post-HTX survival was 78%, 72% and 69% respectively. Variables which were significantly related to study outcomes at univariate and multivariate analysis are shown in the Table. Conclusion The higher risk of WL mortality associated with variables that reflect disease severity and medical urgency is limited by allocation rules. Blood type 0 pts are disadvantaged in the current system. 1-y probability of both getting HTX and dying on the WL was lower in LVAD pts. Short term MCS and emergency HTX were associated with higher rate of death after HTX only at univariate analysis: predictors of post-HTX death should be analyzed separately in these high-risk subgroups.

Background: There is controversy about the outcome of patients with acute myocarditis (AM), and data are lacking on how patients admitted with suspected AM are managed. We report characteristics, in-hospital management, and long-term outcome of patients with AM based on a retrospective multicenter registry from 19 Italian hospitals. Methods: A total of 684 patients with suspected AM and recent onset of symptoms (70 years of age and those >50 years of age without coronary angiography were excluded. The final study population comprised 443 patients (median age, 34 years; 19.4% female) with AM diagnosed by either endomyocardial biopsy or increased troponin plus edema and late gadolinium enhancement at cardiac magnetic resonance. Results: At presentation, 118 patients (26.6%) had left ventricular ejection fraction P P P =0.18). After a median time of 196 days, 200 patients had follow-up cardiac magnetic resonance, and 8 of 55 (14.5%) with complications at presentation had left ventricular ejection fraction Conclusions: In this contemporary study, overall serious adverse events after AM were lower than previously reported. However, patients with left ventricular ejection fraction

Platelets play a key role in the pathogenesis of ventricular assist device (VAD) thrombosis; therefore, antiplatelet drugs are essential, both in the acute phase and in the long-term follow-up in VAD management. Aspirin is the most used agent and still remains the first-choice drug for lifelong administration after VAD implantation. Anticoagulant drugs are usually recommended, but with a wide range of efficacy targets. Dual antiplatelet therapy, targeting more than one pathway of platelet activation, has been used for patients developing a thrombotic event, despite an increased risk of bleeding complications. Although different strategies have been attempted, bleeding and thrombotic events remain frequent and there are no uniform strategies adopted for pharmacological management in the short and mid- or long-term follow up. The aim of this article is to provide an overview of the evidence from randomized clinical trials and observational studies with a focus on the pathophysiologic mechanisms underlying bleeding and thrombosis in VAD patients and the best antithrombotic regimens available.

Recent evidence suggests that the vasoprotective effects of HDL are impaired in patients during an acute coronary syndrome (ACS). In particular, HDL from ACS patients are defective in promoting nitric oxide (NO) release from cultured endothelial cells (ECs). Lecithin:cholesterol acyltransferase (LCAT) plays a key role in HDL maturation and remodeling, and it is the enzyme responsible for cholesterol esterification in plasma. Very few studies have suggested that LCAT activity is decreased during an acute myocardial infarction, but the possible link between LCAT mass/activity and the HDL dysfunction observed in ACS has never been tested. To test this hypothesis, plasma from 30 STEMI patients was collected at admission, 48 and 72 hours and 30 days after event. LCAT concentration and activity significantly decreased 48 hours after event (-0.49±0.11 μg/ml, PIn vitro studies were performed in which STEMI patients’ plasma was added with rhLCAT and HDL vasoprotective activity assessed by measuring NO production in ECs. In vitro incubation of STEMI patients’ plasma with rhLCAT remodels phospholipids and protein content in HDL and restores HDL ability to promote endothelial NO production (+25%, P=0.03). Impairment of cholesterol esterification may be a major factor in the HDL dysfunction observed during ACS. rhLCAT is able to restore HDL-mediated NO production in vitro, suggesting LCAT as potential therapeutic target for restoring HDL functionality in ACS.

Objective: Prior studies have suggested that the principal determinants of arterial stiffening are age, BP and others CV risk factors such as dyslipidemia and diabetes. However, scanty data are available on the role of psychological factors on arterial stiffness. The aim of the current cross-sectional study was to evaluate the association between depression, anxiety, perceived stress, Type A personality, and Type D personality and Pulse Wave Velocity (PWV) in a cohort of hypertensive patients, using baseline examination data of the TIPICO project. Methods: A total of 259 outpatients (ages 18–80 years) followed by the Hypertension Unit of S. Gerardo Hospital (Monza, Italy) affected by essential hypertension were recruited. Aortic stiffness was evaluated by c-f PWV. Moreover, anamnestic data, clinical BP, and laboratory data were evaluated. Patients were asked to complete a battery of psychological questionnaires under the guidance of a psychologist. Results: At T0 mean age was 55.9±10.1years, SBP/DBP were 135.6±17.7/82.5±9.1 mmHg and PWV was 8.6±2.1m/s. The multivariate stepwise linear regression analysis showed that age (beta = 0.284, p < 0.001), pulse pressure (beta = 0.369, p < 0.001), dyslipidemia (beta = 0.130, p = 0.012), family history of CV disease (beta = −0.123, p = 0.017), and depression (beta = 0.126, p = 0.014) were significantly and independently associated with PWV. Conclusion: Among psychological factors, higher levels of depression is related to higher PWV, while anxiety, perceived stress, Type-A personality and Type-D personality are not. Depression assessment and target intervention to reduce it should be recommended in hypertensive patients.

Background: To date no definitive results exist about the relationship of Serum Uric Acid (SUA) and TOD in HT subjects. We sought to determine if such an association exist between SUA and subclinical cardiac, vascular and renal alterations in HT. Methods: We enrolled 632 consecutive outpatients, followed by the Hypertension Unit of S. Gerardo Hospital (Monza, Italy) affected by essential HT. We evaluated anamnestic data, clinical BP and laboratory data as well as TOD with cardiac echocardiography (both as LMVI and diastolic function – E/A), carotid ultrasound (IMT), arterial stiffness (PWV) and renal function analysis (creatinine and microalbumiuria). Results: Age was 53.4±12.7 years, SBP/DBP were 140.5±18.8 and 85.1±13.1 mmHg and SUA was 5.2±1.4 mg/dL. Regarding TOD mean LVMI was 109.6±31.4g/m2, IMT 0.71±0.1 mm, PWV 8.5±2.2 m/s, while creatinine and microalbuminuria were 0.8±0.2 mg/dL and 25.4±126.1 mg/24h respectively. When subjects were divided into high and low SUA group (depending on the median SUA of 5.2 mg/dL), with similar age and BP values the first group showed significantly higher values of metabolic index (BMI, HDL chol, triglycerides and glucose, p < 0.001), LVMI (117.1±32.8 vs 102.1±28.1g/m2, p < 0.01), IMT (0.73±0.1 vs 0.70±0.1mm, p = 0.04), PWV (8.8±2.4 vs 8.3±2.1m/s, p = 0.01) and creatinine (0.9±0.2 vs 0.7±0.1 mg/dL, p < 0.01) and lower E/A (1,0±0.3 vs 1.1±0.3, p < 0.01). SUA showed significant correlation with sex, age, BMI, SBP, HDL chol, triglicerides, glucose, creatinine, IMT, LVMI and E/A. Regarding TOD only creatinine presents SUA as as significant determinant in logistic regression analysis. Conclusion: In HT, SUA values correlate with metabolic derangements and with cardiac, vascular and renal TOD. The most significant correlation is with renal damage.

Objective: Annexin A5 (AnxA5) has been previously linked to the presence of carotid and cardiac target organ damage (TOD) in the context of heart failure and rheumatologic patients. However, information is scant in the context of hypertension. Aim of our study was to evaluate AnxA5 in treated hypertension patients compared with normotensive controls and to determine whether it is associated with vascular and heart TOD evaluated as arterial stiffness, carotid plaque and left ventricular hypertrophy. Methods: We enrolled 123 consecutive treated hypertension and 124 normotensive controls. TOD was evaluated as pulse wave velocity (PWV, complior), left ventricular hypertrophy (echocardiography) and intima-media thickness and carotid plaque presence (ecographic methods). AnxA5 levels was dosed and compared in patients with and without hypertension and with and without TOD. Results: With similar age hypertension patients showed higher SBP, DBP and AnxA5 levels (13.9 ± 11.1 vs 10.1 ± 8.4 ng/ml, P < 0.001) compared with controls. Regarding TOD hypertension showed higher PWV (8.5 ± 1.8 vs 7.6 ± 1.5 m/s, P < 0.001) and LVMI (121.7 ± 29.3 vs 113.5 ± 21.1 g/m2, P < 0.05), whereas carotid intima-media thickness was superimposable. AnxA5 correlates with PWV (r = 0.13, P < 0.05) and DBP (r = 0.15, P < 0.01), whereas it has never been found as a significant independent predictor of TOD in linear regression analysis. Conclusion: Our data have shown that AnxA5 levels are increased in treated hypertension patients. In this condition, it is probably released in the plasma as a defensive mechanism through its anti-inflammatory and anticoagulants effects. We found a significant association with arterial stiffness, but AnxA5 was not found to be a significant predictor of TOD.

Background: Previous reports have suggested that despite their dramatic presentation, patients with fulminant myocarditis (FM) might have better outcome than those with acute nonfulminant myocarditis (NFM). In this retrospective study, we report outcome and changes in left ventricular ejection fraction (LVEF) in a large cohort of patients with FM compared with patients with NFM. Methods: The study population consists of 187 consecutive patients admitted between May 2001 and November 2016 with a diagnosis of acute myocarditis (onset of symptoms Results: In the whole population (n=187), the rate of in-hospital death or heart transplantation was 25.5% versus 0% in FM versus NFM, respectively ( P P P P =0.003). Similar results for survival and changes in LVEF in FM versus NFM were observed in the subgroup (n=130) with viral myocarditis. None of the patients with NFM and LVEF ≥55% at discharge had a significant decrease in LVEF at follow-up. Conclusions: Patients with FM have an increased mortality and need for heart transplantation compared with those with NFM. From a functional viewpoint, patients with FM have a more severely impaired LVEF at admission that, despite steep improvement during hospitalization, remains lower than that in patients with NFM at long-term follow-up. These findings also hold true when only the viral forms are considered and are different from previous studies showing better prognosis in FM.

Purpose Cardiac Allograft Vasculopathy (CAV) is one of the most frequent long-term causes of death after heart transplant (HTx). Immunological and non-immunological factors are implicated in its development. IVUS is the gold standard for CAV diagnosis. Our study evaluates the correlation between the intimal index (IntIndx=[(intimal area/vessel area)*100]) evaluated with IVUS at 1-year after HTx (as a marker of CAV), the presumed pathogenetic factors for early CAV and 10-year cardiovascular (CV) mortality. Methods From January 2008 and June 2009, 28 patients (Pts) underwent IVUS at one-year follow-up after HTx (Female 32,1%, mean age 49,3±10,6 ). According to literature, we used a 40% Intindx cut-off to identify CAV. Study sample was divided into two groups: group A (GA: IntIndx Results Overall 10-year mortality was 21.4% (6 PTs), while 10-year CV mortality was 7.1% (2 Pts, 1 Pts died for heart failure due to advanced CAV, while 1 Pts underwent re-transplant due to end-stage CAV). LAD IntIndx ≥40% was significantly associated with serum HDL at 1-month post-HTx (GA 61.6±12.7 vs GB 49.2±11.3 mg/dl; p 0.012), 1-year post-HTx serum Triglycerides (GA 134.4±29.3 vs GB 179.9±65.9 mg/dl; p 0.041), the percentage of Pts with serum ciclosporine (CyA) in therapeutic range 2 hours after ingestion (GA 91.9%±8% vs GB 78.8±18%; p 0.034), donor age (GA 38.3±12.7 vs 47.4±8.8 year; p 0.003), and donated heart ischemic time (GA 178.6±41.6 vs GB 150.7±29.1 min; p 0.046). Serum HDL at 1-, 6- and 12-months post-HTx, donor age, early positive CMV antigenemia (pp65>50 cells), were also statistically significant risk-facotrs for CAV at 1-year. Conclusion The low even-rate did not allow to compare 10-year CV mortality with IVUS findings, however, despite the small number of patients, our study shows a correlation between IVUS intimal thickness and various risk factors potentially implicated in CAV development and pathogenesi (donor age, CMV infections, non-adequate immune-suppression, and lipid profile after HTx). Further analysis on 1-year IVUS findings and non fatal CAV event are mandatory to better understand IVUS role in heart transplant recipient.

Ancient non-medical texts can unexpectedly provide useful information on the development of knowledge about the heart and its diseases throughout history. The 750th anniversary of the birth of the Italian poet Dante Alighieri (1265-1321) provides a timely opportunity to analyze medical references in his works, in particular, focusing on literary descriptions that may be attributed to cardiovascular disorders. Dante's high level of medical knowledge, probably derived from his academic studies, is testified by his affiliation to the Florentine Guild of physicians and pharmacists. In all his works, the poet shows a deep interest for the heart. However, his anatomical and physiological knowledge of the circulatory system appears to be poor, probably due to it being based on theories and concepts brought forth by Aristotle and Galen, which were taught in medieval universities. Despite this, accurate descriptions of some symptoms (emotional syncope, orthopnea, dyspnea on exertion) and signs (ascites, paleness), which may be attributed to cardiovascular disorders, can be easily found in Dante's works, particularly in his masterpiece, the Divine Comedy. The literary and historical analysis of cardiovascular signs and symptoms allows us to assume that clinical features due to alterations of heart function were probably known by medieval physicians, but their etiology and pathophysiological mechanisms were not completely understood in that period. Historians of cardiology and clinicians should consider analysis of non-medical texts (including poetry) as an opportunity to better investigate the evolution of their discipline throughout the ages.

Objective. Evidence exists that arterial stiffness, i.e. an independent predictor of cardiovascular and all-causes mortality, has a genetic component. The 9p21 region is associated with a greater susceptibility to coronary disease. Whether this can be ascribed to the fact that genes located on chromosome 9p may also regulate arterial stiffness is largely unknown, however. We evaluate the influence of single nucleotide polymorphisms (SNPs) from 9p on carotid–femoral pulse wave velocity (C-F PWV), measured via the Complior method, in a cohort of 821 hypertensive subjects. Design. The selected tagSNPs were screened with a custom-designed 384-plex VeraCode GoldenGate Genotyping assay on Illumina BeadXpress Reader platform. Association analysis was done using PLINK considering C-F PWV as a quantitative trait (linear regression assuming an additive model) adjusting for sex, age, systolic blood pressure and body mass index (BMI). We used false discovery rate (FDR) to account for multiple testing. Results. Although none of the 384 SNPs was significant after adjusting for multiple testing, probably due to the small sample size of the study population, a trend of association with C-F PWV was observed for rs300622 and rs2381640. Conclusions. These data suggest that SNPs located on chromosome 9p may affect arterial stiffness. Further studies are needed to confirm our finding on a larger sample and define the physiopathological link of the present results

Background: Hypercalcemia induces arrhythmias and shortening of QT. The aim of this study was to investigate risk factors for occurrence of arrhythmias in patients with primary hyperparathyroidism (PHPT) during bicycle ergometer exercise test (ET). Methods: Thirty PHPT postmenopausal women (mean age, 60·9 ± 8·0 years) and 30, sex and age-matched, controls underwent ET, echocardiogram and mineral metabolism biochemical evaluation. The following stages were considered during ET: rest, peak exercise, recovery (early recovery, 2 and 10 min after peak exercise). QT was corrected with Bazett's formula (QTc). Results: Compared with controls, PHPT patients showed an increased occurrence of ventricular premature beats (VPBs) during ET (26·6% vs. 6·6%, P = 0·03). Being affected by PHPT predicted the onset of VPBs at peak exercise (P = 0·04) and recovery (P = 0·03), as shown by logistic regression analysis. In PHPT patients, serum calcium level was a predictor of VPBs at peak exercise (P = 0·05). QTc in patients with PHPT was in the normal range. Serum calcium level showed a negative correlation with QTc (P = 0·01) in whole sample. Compared with controls, PHTP patients had QTc significantly shorter for every stage of ET, except at peak exercise. Physiological reduction of QTc interval from rest to peak exercise was not seen in patients with PHPT, QTc at rest being the only predictor of QTc in every stage, as shown by multivariate regression analysis. Conclusions: In patients with PHPT, an increased occurrence of VPBs and a different QTc adaptation during ET were observed and may represent risk factors for major arrhythmias. © 2012 Stichting European Society for Clinical Investigation Journal Foundation.

OBJECTIVES In Europe, the age of heart donors is constantly increasing. Ageing of heart donors limits the probability of success of heart transplantation (HTx). The aim of this study is to compare the outcome of patients with advanced heart failure (HF) treated with a continuous-flow left ventricular assist device (CF-LVAD) with indication as bridge to transplantation (BTT) or bridge to candidacy (BTC) versus recipients of HTx with the donor's age above 55 years (HTx with donors >55 years). METHODS we prospectively evaluated 301 consecutive patients with advanced HF treated with a CF-LVAD (n = 83) or HTx without prior bridging (n = 218) in our hospital from January 2006 to January 2015. We compared the outcome of CF-LVAD-BTT (n = 37) versus HTx with donors >55 years (n = 45) and the outcome of CF-LVAD-BTT plus BTC (n = 62) versus HTx with donors >55 years at the 1- and 2-year follow-up. Survival was evaluated according to the first operation. RESULTS The perioperative (30-day) mortality rate was 0% in the LVAD-BTT group vs 20% (n = 9) in the HTx group with donors >55 years (P = 0.003). Perioperative mortality occurred in 5% of the LVAD-BTT/BTC patients (n = 3) and in 20% of the HTx with donors >55 year group (P = 0.026). Kaplan-Meier curves estimated a 2-year survival rate of 94.6% in CF-LVAD-BTT vs 68.9% in HTx with donors >55 years [age- and sex-adjusted hazard ratio (HR) 0.25; 95% confidence interval (CI) 0.08-0.81; P = 0.02 in favour of CF-LVAD]. Considering the post-HTx outcome, a trend in favour of CF-LVAD-BTT was also observed (age- and sex-adjusted HR 0.45; 95% CI 0.17-1.16; P = 0.09 in favour of CF-LVAD), whereas CF-LVAD-BTT/BTC showed a similar survival at 2 years compared with HTx with donors >55 years, both censoring the follow-up at the time of HTx and considering the post-HTx outcome. CONCLUSIONS Early and mid-term outcomes of patients treated with a CF-LVAD with BTT indication seem better than HTx with old donors. It must be emphasized that up to 19% of patients in the CF-LVAD/BTT group underwent transplantation in an urgent condition due to complications related to the LVAD. At the 2-year follow-up, CF-LVAD with BTT and BTC indications have similar outcome than HTx using old heart donors. These results must be confirmed in a larger and multicentre population and extending the follow-up.

Renal denervation (RD) is an intriguing treatment strategy for resistant hypertension. However, limited data are available about its long time efficacy as well as its effects on intermediate phenotypes like arterial stiffness and carotid IMT. 12 patients (9 males, mean 69 years) with resistant hypertension underwent bilateral RDN (Medtronic System) since April 2012 in Niguarda Ca’ Granda Hospital (Milan). Patients were studied before intervention, and at 1, 3, 6 and 12 months after RD. Carotid intima media thickness (Esaote Mylab) and carotid-femoral pulse wave velocity (Complior, Alam medical) were assessed at each step. Compared to baseline, patients showed a marked reduction of office systolic blood pressure at each follow-up step (p

Early vascular aging is a process characterized by a reduction in arterial elastin with an increase in collagen that has been related to cardiovascular risk factor and can determine an increased arterial stiffness and central blood pressure. It can be measured by several non invasive methods and in different arterial segment. The present paper will focus on functional (local stiffness parameter) and structural (intima media thickness) carotid arteries alterations typically evaluated by ultrasound methods. Methodological, research and clinical issue has been reviewed.
