[Heavy metal! A case of severe iron overload and supraventricular arrhythmias in a thalassemia major patient]. / Heavy metal! Un caso di severo accumulo di ferro e aritmie sopraventricolari in paziente con talassemia major.

Cardiovascular complications are among the main causes of mortality and morbidity in patients with thalassemia major. Iron-chelation therapy is essential to prevent the chronic iron overload linked to the need for transfusions and the consequent cardiac hemosiderosis. Despite the wide use of iron-chelation drugs, today it is still possible to find cases of severe iron accumulation. Furthermore, even regardless of iron overload and cardiac dysfunction, the thalassemic patient has a high arrhythmic burden, especially for supraventricular arrhythmias. There are still many doubts and open questions about the management of such patients, especially regarding the correct use of anticoagulant therapy and the best utilization of therapeutic strategies available for rhythm control. The case presented shows how the interventional approach with catheter ablation can be useful also in the acute phase when antiarrhythmic drugs are ineffective and it is not possible to wait for the iron-chelation therapy to take effect.

Cardiac Dysfunction Due to Thiamine Deficiency after Hemodialysis for Biguanide-related Lactic Acidosis.

Biguanide is an ideal drug for the treatment of type 2 diabetes mellitus. When used appropriately, the incidence of lactic acidosis is reported to be very low. Risk factors associated with biguanide-related lactic acidosis include chronic kidney disease, congestive heart failure, alcohol use, severe dehydration, shock, hypoxic states, sepsis, and advanced age. We herein report a case of cardiac dysfunction due to thiamine deficiency after hemodialysis in a patient with suspected biguanide-related lactic acidosis. Patients who develop severe lactic acidosis while taking biguanides should be given a large dose of thiamine without delay, given the possibility of thiamine deficiency as a complication.

Acupoint Catgut Embedding Reduces Insulin Resistance in Diabetic Patients Undergoing Open Cardiac Surgery.

OBJECTIVE: Acupoint catgut embedding (ACE) has been used safely for thousands of years in traditional Chinese medicine. The aim of this study was to assess whether ACE can improve insulin resistance and promote rapid recovery after open cardiac surgery. METHODS: A group of 200 patients undergoing cardiac surgery were randomly allocated to receive either ACE (ACE group) or sham ACE (SHAM group). The primary outcome of our trial was insulin resistance assessed 1, 3, 5, and 7 days after surgery. The homeostasis model assessment (HOMA-IR) was used to measure perioperative insulin resistance. Secondary outcomes included insulin, glucose, and inflammatory cytokine (interleukin (IL) 6 and IL-8) levels; time to extubation; incidence of infection; time to first feces; acute kidney injury; incidence of postoperative nausea and vomiting (PONV); length of stay in the ICU; length of hospital stay; and other clinical parameters. RESULTS: The ACE group had lower insulin, glucose, IL-6, IL-8, and HOMA-IR levels than the SHAM group one week after the operation. The incidence of infection, incidence of PONV, time to drain removal, and length of hospital stay significantly were lower in the ACE group than in the SHAM group. CONCLUSION: ACE can improve insulin resistance and promote rapid recovery after open cardiac surgery.

The Close Link of Pancreatic Iron With Glucose Metabolism and With Cardiac Complications in Thalassemia Major: A Large, Multicenter Observational Study.

OBJECTIVE: We systematically explored the link of pancreatic iron with glucose metabolism and with cardiac complications in a cohort of 1,079 patients with thalassemia major (TM) enrolled in the Extension-Myocardial Iron Overload in Thalassemia (E-MIOT) project. RESEARCH DESIGN AND METHODS: MRI was used to quantify iron overload (T2* technique) and cardiac function (cine images) and to detect macroscopic myocardial fibrosis (late gadolinium enhancement technique). Glucose metabolism was assessed by the oral glucose tolerance test (OGTT). RESULTS: Patients with normal glucose metabolism showed significantly higher global pancreas T2* values than patients with impaired fasting glucose, impaired glucose tolerance, and diabetes. A pancreas T2* <13.07 ms predicted an abnormal OGTT. A normal pancreas T2* value showed a 100% negative predictive value for disturbances of glucose metabolism and for cardiac iron. Patients with myocardial fibrosis showed significantly lower pancreas T2* values. Patients with cardiac complications had significantly lower pancreas T2* values. No patient with arrhythmias/heart failure had a normal global pancreas T2*. CONCLUSIONS: Pancreatic iron is a powerful predictor not only for glucose metabolism but also for cardiac iron and complications, supporting the close link between pancreatic iron and heart disease and the need to intensify iron chelation therapy to prevent both alterations of glucose metabolism and cardiac iron accumulation.

A pilot study on secondary anemia in "frailty" patients treated with Ferric Sodium EDTA in combination with vitamin C, folic acid, copper gluconate, zinc gluconate and selenomethionine: safety of treatment explored by HRV non-linear analysis as predictive factor of cardiovascular tolerability.

OBJECTIVE: Iron deficiency anemia (IDA) in patients with heart disease is correlated with decreased exercise capacity and poor health-related quality of life, and predicts worse cardiovascular outcomes, especially for elderly patients. IDA can worsen cardiac function that can be monitored with Heart Rate Variability (HRV) analysis, providing important information about cardiac health. In a recent study we explored the effect and the tolerability of the administration of Ferric Sodium EDTA in combination with vitamin C, folic acid, copper gluconate, zinc gluconate and selenomethionine (Ferachel Forte®) in "frailty" patients with secondary anemia and low kidney failure, by analysing the HRV frequency domain. The aim of the present study is the further confirmation of the safety of the already evaluated intervention, by analysing non-linear domain of HRV. PATIENTS AND METHODS: In this pilot study we enrolled 52 "frailty" elderly patients, with a recent diagnosis of secondary anemia due to iron deficiency, with Class II New York Heart Association (NYHA) hypertensive heart disease, low kidney failure, and atherosclerosis. The patients were divided in 2 groups: Group A (N=23 patients) received oral administration of Ferric Sodium EDTA in combination with vitamin C, folic acid, copper gluconate, zinc gluconate and selenomethionine (Ferachel Forte®) 2 tabs/day, containing 60 mg of Fe3+, for 24 days; Group B (N=29 patients) received intravenous administration of ferrous gluconate 63 mg/day added to saline solution, while they were hospitalized (15±5 days). We evaluated laboratory values of hemoglobin (Hb) and sideremia levels. Furthermore, we measured ECG signals before and after treatment, using non-linear analysis techniques. RESULTS: Both intravenous and oral treatments evaluated in this study, were effective and safe about the cardiovascular risk in "frailty" elderly patients, as resulted from non-linear HRV analysis. Efficacy results showed that hemoglobin and sideremia levels after treatments are significantly increased. The HRV non-linear analysis showed that all parameters evaluated, except for the SD1 values in the Group A, were not affected by treatments, confirming the absence of cardiovascular risk of the therapy. CONCLUSIONS: Non-linear HRV evaluation confirmed that oral administration of Ferric Sodium EDTA, in combination with vitamin C, folic acid, copper gluconate, zinc gluconate and selenomethionine (Ferachel forte®) did not impact the cardiovascular risk, without causing adverse events typically reported with other iron supplementation therapies, both oral and intravenous.

Jiao-tai-wan for insomnia symptoms caused by the disharmony of the heart and kidney: a study protocol for a randomized, double-blind, placebo-controlled trial.

BACKGROUND: Insomnia seriously affects people's normal lives and work. However, effective treatment strategies are scarce. The purpose of this study is to explore the efficacy and safety of Jiao-tai-wan (JTW) for ameliorating insomnia symptoms caused by disharmony of the heart and kidney. DESIGN: This is a randomized, double-blind, placebo-controlled pilot clinical trial. A total of 124 participants suffering from insomnia symptoms will be randomly assigned to the JTW or placebo group in an equal ratio. The participants will be asked to take JTW or placebo granules twice a day for 1 week. All data will be gathered at baseline and at the end of the drug intervention. The primary outcome measures will be the mean change in the Pittsburgh Sleep Quality Index (PSQI) from baseline to the end of the drug intervention. Secondary outcome measures will include the altered sleep parameters in polysomnography, 1H-magnetic resonance spectroscopy (1H-MRS) evaluation, the Disharmony of Heart and Kidney Scoring System score, and blood tests, including the levels of serum adenosine and melatonin. A laboratory test will be taken before and after treatment to assess the safety of JTW. DISCUSSION: The outcomes of this study will confirm the efficacy of JTW for the treatment of insomnia symptoms and will also be used to monitor the safety of JTW.

Bright light therapy for depressive symptoms in hospitalized cardiac patients: A randomized controlled pilot trial.

Depression is common among cardiac patients and associated with adverse cardiovascular outcomes. Bright light therapy has emerged as a promising treatment for depressive symptoms, however it has not yet been investigated in this population. We conducted a double-blind, randomized, placebo-controlled pilot trial to assess the feasibility of a larger-scale trial testing bright light therapy for depressive symptoms in cardiac patients. Patients hospitalized for an acute coronary syndrome or undergoing cardiac surgery were randomized to either bright light (10,000 lux) or dim light placebo (500 lux) lamps for 30 minutes each day over 4 weeks, beginning in-hospital. Depression was quantified using the Patient Health Questionnaire 9 (PHQ-9) and Depression Anxiety and Stress Scales (DASS-21). The Short-Form Health Survey 36 (SF-36) was used to measure quality of life. A total of 175 patients were screened and 15 were randomized (8 treatment, 7 placebo) (8.6%) over 10 months. Despite protocol amendments which broadened the inclusion criteria, the trial was terminated early for infeasibility based on the rate of enrollment (1-2 participants/month), with 39.5% of the target sample (38 participants) enrolled. Future trials should take into account the timing of the onset of depressive symptoms in these patients, and consider a less conservative approach to eligibility as well as ways to increase the acceptability of bright light therapy in hospitalized cardiac patients. Once enrolled, our findings suggest that most participants will adhere to the assigned treatment and complete follow-up.

[Gastroesophageal reflux disease with cardial manifistations: perspectives of non-pharmacological treatment methods]. / Gastroézofageal'naia refliuksnaia bolezn' s kardial'nymi proiavleniiami: perspektivy nemedikamentoznykh metodov lecheniia.

In this article we present the review of the literature and our own research regarding gastroesophageal reflux disease (GERD) with cardiac manifestations. The methods of treatment of patients with GERD using mineral waters, physio- and balneotherapeutic factors, as well as acupuncture are discussed. The conclusion is drawn about the effectiveness of the use of non-pharmacological methods in mono- and complex therapy of GERD and the need for further research in this direction.

Tiaobu Xinshen Recipe () Improved Mild Cognitive Impairment of Alzheimer's Disease Patients with Xin (Heart) and Shen (Kidney) Deficiency.

OBJECTIVE: To observe the intervention effects of Tiaobu Xinshen Recipe (, TXR) on patients with mild cognitive impairment caused by Alzheimer's disease (MCI-AD). METHODS: Totally 88 MCI-AD patients with syndrome of Xin (Heart) and Shen (Kidney) deficiency were assigned to the experimental group (47 cases, treated with TXR) and the control group (41 cases, treated with donepezil hydrochloride) using a random number table. Final recruited qualified patients were 44 cases in the experimental group and 39 cases in the control group. The therapeutic course was 12 weeks. Neuropsychological scales [mini mental state examination (MMSE) and Montreal cognitive assessment (MoCA)], and Chinese medicine (CM) dementia syndromes scales were performed in all patients, and results were compared between groups or intra-group before and after treatment. RESULTS: MMSE and MoCA scores of the two groups were increased after treatment compared with those before treatment (P<0.05). But there was no statistical difference in MMSE or MOCA scores after treatment between the two groups (P>0.05). CM dementia syndrome score was significantly decreased after treatment in the experimental group compared with the control group (P<0.01). Visual spatial and executive function scores and delayed recall scores of the two groups were increased compared with those before treatment (P<0.01). CONCLUSION: TXR could effectively improve cognitive impairment of MCI-AD patients with syndrome of Xin and Shen deficiency.

[ANMCO Position paper: From acute to chronic disease: the needs of complex cardiac patients]. / Position paper ANMCO: Bisogni assistenziali del malato cardiopatico complesso: dalla fase acuta alla fase cronica.

Managing a patient suffering from a chronic disease requires a multidisciplinary team that can take care of them beyond the simple coordination of various specialties. In this context, a central role in the treatment of chronic heart disease is the continuity of care that should promote organic integration among different hospital departments, hospital and community. This position paper of the Italian Association of Hospital Cardiologists (ANMCO) aims at defining the general principles to inspire care for complex cardiac patients at different phases of the disease. A multidisciplinary integrated holistic approach uses analytical tools able to understand the elements that characterize complexity and therefore suggest appropriate management strategies: (i) care pathways aimed at optimizing treatments; (ii) care pathways in intensive care and ward in a multidisciplinary perspective; (iii) integration of social and health needs; (iv) nursing role in the context of continuity of outpatient, community and home care; (v) promotion of educational interventions.

2019 HRS/EHRA/APHRS/LAHRS expert consensus statement on catheter ablation of ventricular arrhythmias.

Ventricular arrhythmias are an important cause of morbidity and mortality and come in a variety of forms, from single premature ventricular complexes to sustained ventricular tachycardia and fibrillation. Rapid developments have taken place over the past decade in our understanding of these arrhythmias and in our ability to diagnose and treat them. The field of catheter ablation has progressed with the development of new methods and tools, and with the publication of large clinical trials. Therefore, global cardiac electrophysiology professional societies undertook to outline recommendations and best practices for these procedures in a document that will update and replace the 2009 EHRA/HRS Expert Consensus on Catheter Ablation of Ventricular Arrhythmias. An expert writing group, after reviewing and discussing the literature, including a systematic review and meta-analysis published in conjunction with this document, and drawing on their own experience, drafted and voted on recommendations and summarized current knowledge and practice in the field. Each recommendation is presented in knowledge byte format and is accompanied by supportive text and references. Further sections provide a practical synopsis of the various techniques and of the specific ventricular arrhythmia sites and substrates encountered in the electrophysiology lab. The purpose of this document is to help electrophysiologists around the world to appropriately select patients for catheter ablation, to perform procedures in a safe and efficacious manner, and to provide follow-up and adjunctive care in order to obtain the best possible outcomes for patients with ventricular arrhythmias.

SGLT-2 inhibitors and GLP-1 receptor agonists for nephroprotection and cardioprotection in patients with diabetes mellitus and chronic kidney disease. A consensus statement by the EURECA-m and the DIABESITY working groups of the ERA-EDTA.

Chronic kidney disease (CKD) in patients with diabetes mellitus (DM) is a major problem of public health. Currently, many of these patients experience progression of cardiovascular and renal disease, even when receiving optimal treatment. In previous years, several new drug classes for the treatment of type 2 DM have emerged, including inhibitors of renal sodium-glucose co-transporter-2 (SGLT-2) and glucagon-like peptide-1 (GLP-1) receptor agonists. Apart from reducing glycaemia, these classes were reported to have other beneficial effects for the cardiovascular and renal systems, such as weight loss and blood pressure reduction. Most importantly, in contrast to all previous studies with anti-diabetic agents, a series of recent randomized, placebo-controlled outcome trials showed that SGLT-2 inhibitors and GLP-1 receptor agonists are able to reduce cardiovascular events and all-cause mortality, as well as progression of renal disease, in patients with type 2 DM. This document presents in detail the available evidence on the cardioprotective and nephroprotective effects of SGLT-2 inhibitors and GLP-1 analogues, analyses the potential mechanisms involved in these actions and discusses their place in the treatment of patients with CKD and DM.

The Non-Vitamin K Antagonist Oral Anticoagulants in Heart Disease: Section V-Special Situations.

Non-vitamin K antagonist oral anticoagulants (NOACs) include dabigatran, which inhibits thrombin, and apixaban, betrixaban, edoxaban and rivaroxaban, which inhibit factor Xa. In large clinical trials comparing the NOACs with the vitamin K antagonist (VKA) warfarin, dabigatran, apixaban, rivaroxaban and edoxaban were at least as effective for stroke prevention in atrial fibrillation and for treatment of venous thromboembolism, but were associated with less intracranial bleeding. In addition, the NOACs are more convenient to administer than VKAs because they can be given in fixed doses without routine coagulation monitoring. Consequently, the NOACs are now replacing VKAs for these indications, and their use is increasing. Although, as a class, the NOACs have a favourable benefit-risk profile compared with VKAs, choosing among them is complicated because they have not been compared in head-to-head trials. Therefore, selection depends on the results of the individual trials, renal function, the potential for drug-drug interactions and preference for once- or twice-daily dosing. In addition, several 'special situations' were not adequately studied in the dedicated clinical trials. For these situations, knowledge of the unique pharmacological features of the various NOACs and judicious cross-trial comparison can help inform prescription choices. The purpose of this position article is therefore to help clinicians choose the right anticoagulant for the right patient at the right dose by reviewing a variety of special situations not widely studied in clinical trials.

Dabigatran as an alternative for atrial thrombosis resistant to rivaroxaban: A case report.

RATIONALE: Anti-thrombosis therapy for atrial fibrillation (AF) management and stroke prevention is an important aspect of disease management. Novel oral anticoagulants (NOACs) are recommended by guidelines for AF management. However, if one can switch one NOAC to another when the former showed a poor effect has not been fully determined. PATIENT CONCERNS: A 52-year-old man was admitted to our center for heart failure and AF with a thrombus in the left atrium. DIAGNOSES: Cardiomyopathy was diagnosed by cardiac magnetic resonance (CMR) and echocardiography. INTERVENTIONS: He was prescribed rivaroxaban (20 mg daily) as treatment, and dabigatran (150 mg twice daily) was used when the thrombus was found to be non-response to rivaroxaban. OUTCOMES: The rivaroxaban did not diminish the atrial thrombus, and dabigatran was given instead which finally eliminated the thrombus. LESSONS: Individualized responsiveness to NOACs should be considered and paid more attention to during clinical practice.

Aortic Dissection and Cardiac Dysfunction Emerged Coincidentally During the Long-Term Treatment with Angiogenesis Inhibitors for Metastatic Renal Cell Carcinoma.

Angiogenesis inhibitors, such as sorafenib and axitinib, which target vascular endothelial growth factor (VEGF) signaling, are widely used for renal cell carcinoma, including metastasis. In this study, we report a case of cardiovascular adverse events of aortic dissection and cardiac dysfunction during treatment with sorafenib and axitinib for metastatic renal cell carcinoma. A 66-year-old man had been administered sorafenib for 2 years after nephrectomy due to renal cell carcinoma. To control the progression of metastatic lung tumor, axitinib was started after sorafenib for four years. During the treatment, angiotensin II type 1 receptor blockers and Ca antagonists were used to strictly control the axitinib-induced hypertension and proteinuria. Aortic dissection and cardiac dysfunction occurred coincidentally. Considering the critical role of VEGF signaling in the homeostasis of the cardiovascular system, we speculated that the long-term use of axitinib and sorafenib directly influenced the initiation of aortic dissection and cardiac dysfunction. Although the precise mechanisms underlying the aortic dissection and cardiac dysfunction induced by angiogenesis inhibition are still elusive, onco-cardiologists and oncologists should pay careful attention to cardiovascular toxicity and complications in patients with cancer, particularly patients undergoing long-term cancer treatment.

Non-invasive epicardial and endocardial electrocardiographic imaging for scar-related ventricular tachycardia.

Aims: Contact mapping is currently used to guide catheter ablation of scar-related ventricular tachycardia (VT) but usually provides incomplete assessment of 3D re-entry circuits and their arrhythmogenic substrates. This study investigates the feasibility of non-invasive electrocardiographic imaging (ECGi) in mapping scar substrates and re-entry circuits throughout the epicardium and endocardium. Methods and results: Four patients undergoing endocardial and epicardial mapping and ablation of scar-related VT had computed tomography scans and a 120-lead electrocardiograms, which were used to compute patient-specific ventricular epicardial and endocardial unipolar electrograms (CEGMs). Native-rhythm CEGMs were used to identify sites of myocardial scar and signal fractionation. Computed electrograms of induced VT were used to localize re-entrant circuits and exit sites. Results were compared to in vivo contact mapping data and epicardium-based ECGi solutions. During native rhythm, an average of 493 ± 18 CEGMs were analysed on each patient. Identified regions of scar and fractionation comprised, respectively, 25 ± 4% and 2 ± 1% of the ventricular surface area. Using a linear mixed-effects model grouped at the level of an individual patient, CEGM voltage and duration were significantly associated with contact bipolar voltage. During induced VT, the inclusion of endocardial layer in ECGi made it possible to identify two epicardial vs. three endocardial VT exit sites among five reconstructed re-entry circuits. Conclusion: Electrocardiographic imaging may be used to reveal sites of signal fractionation and to map short-lived VT circuits. Its capacity to map throughout epicardial and endocardial layers may improve the delineation of 3D re-entry circuits and their arrhythmogenic substrates.

Bleeding Complications After Use of Novel Oral Anticoagulants in Patients Undergoing Cardiac Surgery.

BACKGROUND: The study was performed to analyze the results of open-heart surgery and bleeding complications after administration of novel oral anticoagulants (NOAC). METHODS: We investigated 81 consecutive patients (median age 74 years, interquartile range [IQR]: 68 to 78) who underwent open-heart operations at our institution between July 2014 and June 2016. All patients presented for surgery while on NOAC therapy: 37 received rivaroxaban (45.7%), 35 apixaban (43.2%), and 9 dabigatran (11.1%). The calculated risk using the European System for Cardiac Operative Risk Evaluation II was 3.5% (IQR: 2.0% to 8.1%). RESULTS: Surgery was performed at a median 4 days (IQR: 3 to 6) after NOAC withdrawal. Reduced renal function was predictive for length of intensive care unit stay and administration of red blood cells (p < 0.0001 and p = 0.0291, respectively). The NOAC withdrawal interval significantly influenced postoperative drainage volume (p = 0.0056). Five patients needed rethoracotomy because of relevant bleeding (6.2%), 4 after apixaban (11.4%) and 1 after rivaroxaban therapy (2.7%). Apixaban showed a borderline influence on prolonged intensive care unit stay (p = 0.0736). Prolonged cardiopulmonary bypass time was predictive for thrombocyte administration (p = 0.0249). Intensive care unit stay was 2 days after NOAC withdrawal of 10 days, compared with 4.2 days without termination. Thirty-day mortality was 3.7%. CONCLUSIONS: A lengthy NOAC withdrawal period, particularly for patients with reduced renal function, is essential for safe open-heart surgery. We conclude that despite official recommendations, patients should whenever possible not be considered for elective cardiac surgery within 10 days of terminating NOAC treatment.

The CoCoS trial: Caloric Control in Cardiac Surgery patients promotes survival, an interventional trial with retrospective control.

BACKGROUND & AIMS: Malnutrition is widespread among cardiac surgery patients and is independently related to an adverse postoperative evolution or outcome. We aimed to assess whether nutrition therapy (NT) could alter caloric deficit, morbidity, and mortality in patients scheduled for non-emergency coronary artery bypass graft (CABG) or aortic valve surgery. METHODS: 351 patients undergoing either elective CABG or aortic valve surgery were studied. Patients receiving NT were enrolled from January 2013 until December 2014. A retrospective control group (CT) consisted of 142 matched patients. The primary endpoint was to evaluate whether NT could limit caloric deficit (Intake to Need Deviation). Secondary endpoints addressed the potential effect of NT on morbidity and mortality. Patients were followed for one year after surgery. RESULTS: There was no significant difference in patient, laboratory or mortality profile between the groups. Caloric deficit could be limited in the intervention group, essentially by providing oral feeding and oral supplements. A minority of patients required enteral or parenteral nutrition during their hospital stay. Caloric deficit increased after the second postoperative day because more patients were switched to oral feeding and intravenous infusions were omitted. Combining CABG and aortic valve surgery, male patients in the NT group had significantly less arrhythmia than in the CT group (7% versus 31%; P = 0.0056), while females in the NT group had significantly less pneumonia than in the CT group (7% versus 22%; P = 0.0183). Survival was significantly higher in female NT patients compared to CT patients, both for CABG (100% versus 83%; P = 0.0015) and aortic valve surgery (97% versus 78%; P = 0.0337). CONCLUSION: The results suggest that NT beneficially affects morbidity and mortality in elective cardiac surgery patients. The impact of NT seems more pronounced in women than in men.
