REVIEW
Peter A Henriksen
Anthracycline chemotherapy causes dose-related cardiomyocyte injury and death leading to left ventricular dysfunction. Clinical heart failure may ensue in up to 5% of high-risk patients. Improved cancer survival together with better awareness of the late effects of cardiotoxicity has led to growing recognition of the need for surveillance of anthracycline-treated cancer survivors with early intervention to treat or prevent heart failure. The main mechanism of anthracycline cardiotoxicity is now thought to be through inhibition of topoisomerase 2β resulting in activation of cell death pathways and inhibition of mitochondrial biogenesis...

Heart failure (HF) continues to grow as a cause of morbidity and mortality in our community and presents a significant public health problem, predominantly in individuals ≥65 years of age. Early intervention in asymptomatic HF subjects (Stage A/B) at risk of progression to symptomatic HF (Stage C/D) may provide an opportunity to halt this epidemic. The ability of cardiac imaging to assess cardiac structure and function permits early identification of those at increased risk of developing symptomatic HF. Systolic, diastolic, and structural left ventricular parameters each predict symptomatic HF, but no single parameter has sufficient sensitivity for screening to identify individuals with Stage A/B HF who are at increased risk of disease progression...

BACKGROUND: The utility of biomarkers for prognostication of long term outcomes in patients with anaemia and heart failure(HF) is not well defined. The objective of this study was to assess the ability of a novel biomarker, bio-width index (BWI),to improve risk stratification in patients with anaemia and acutely decompensated heart failure(ADHF), in comparison to conventional markers, B-type natriuretic peptide(BNP) and red- cell distribution width(RDW). METHODS: Data from 1569 consecutive patients with ADHF treated at a multidisciplinary HF unit was analysed in this study...

PURPOSE: Obesity is often associated with better clinical outcomes in heart failure (HF). This so-called obesity paradox remains controversial. The aim of present study was to investigate the prognostic value of obesity in patients hospitalized for systolic HF. MATERIALS AND METHODS: We performed a pooled analysis of data from two multicenter, observational HF studies. Patients hospitalized for systolic HF were eligible for the present study. We divided the subjects into two groups, a normal body mass index (BMI) group and a high BMI group...

Background: Carvedilol is used in the management of hypertension, ischemic heart disease, heart failure and most recently, portal hypertension. It has been associated with improved outcomes regarding variceal bleeding, hepatic decompensation and death when compared to propranolol and endoscopic band ligation. The main cause of portal hypertension is cirrhosis and therefore carvedilol is increasingly used in these patients. Due to its extensive hepatic metabolism, carvedilol is contraindicated in severe hepatic impairment...

BACKGROUND: Metastatic cardiac tumors may cause different symptoms including angina, symptoms of heart failure and/or arrhythmia. In patients with concomitant coronary artery disease, it may be difficult to distinguish between angina caused by metastases to the heart, for example, by stealing perfusion from the coronary arteries, and angina caused by coronary stenosis. Identifying the origin of the symptoms is, however, essential for designing appropriate surgical strategies. CASE PRESENTATION: A 69-year-old male with multifocal recurrence of a hepatocellular carcinoma (HCC) presented with increasing ventricular arrhythmia and angina several weeks after posterior myocardial infarction and PCI of the RCA culprit lesion during which two further lesions present in the distal RCX and a posterolateral branch, and a chronically occluded LAD had not been addressed...

This report describes a case of nonbacterial thrombotic endocarditis caused by Waldenström macroglobulinemia, with diffuse endocardial lesions and involvement of all 4 cardiac valves. A 77-year-old man presented with heart failure due to severe regurgitation of all 4 cardiac valves; surgical repair using bioprosthetic valves was indicated. A pathological study revealed fibrin-triggered thrombus formation that confirmed the diagnosis of nonbacterial thrombotic endocarditis. In cases of nonbacterial thrombotic endocarditis, the underlying cause should be investigated...

INTRODUCTION: The pacemaker implantation VDD is considered simpler, faster, less expensive and causes fewer complications compared to DDD. However, the VDD pacemaker has not been widely used in many centers, perhaps for fear of dysfunction of the sinus node and the reduction of atrial sensitivity by the pacemaker during follow-up after implantation. OBJECTIVE: To compare patients with DDD and VDD pacemakers regarding the evolution of chronic atrial fibrillation (AF) and length of stay outside this postoperative arrhythmia...

This study was conducted with the aim of comparing the effects of Benson muscle relaxation and nature sounds on fatigue in patients with heart failure. Fatigue and exercise intolerance as prevalent symptoms experienced by patients with heart failure can cause the loss of independence in the activities of daily living. It can also damage self-care and increase dependence to others, which subsequently can reduce the quality of life. This randomized controlled clinical trial was conducted in an urban area of Iran in 2016...

BACKGROUND: It remains unclear into which level the systolic blood pressure (SBP) should be lowered in order to provide the best cardiovascular protection among older people. Hypertension guidelines recommendation on attaining SBP levels <150 mmHg in this population is currently based on experts' opinion. To clarify this issue, we systematically reviewed and quantified available evidence on the impact of achieving different SBP levels <150 mmHg on various adverse outcomes in subjects aged ≥60 years old receiving antihypertensive drug treatment...

Antiepileptic Drugs (AEDs) are commonly associated with haematological disorders, including anaemia, thrombocytopenia, neutropenia and even bone marrow failure. Fatal disorders like aplastic anaemia are uncommon. On exploring through the literature, older AEDs are more associated with haematological alterations than newer AEDs, and careful monitoring is warranted especially with phenytoin, carbamazepine and valproate. The exact cause of these alterations is not established, though immune mechanisms and pharmacology of individual drugs are the proposed mechanisms, a further research along this path is underway...

AIMS: The Z-disc is a crucial structure of the sarcomere and is implicated in mechanosensation/transduction. Dysregulation of Z-disc proteins often result in cardiomyopathy. We have previously shown that the Z-disc protein Cytoskeletal Heart-enriched Actin-associated Protein (CHAP) is essential for cardiac and skeletal muscle development. Furthermore, the CHAP gene has been associated with atrial fibrillation in humans. Here, we studied the misregulated expression of CHAP isoforms in heart disease...
