INTRODUCTION: Hodgkin lymphoma (HL) is one of the most common types of cancers of the lymphatic system. The currently available therapies enable a cure in approximately 80-85% of treated patients. However, the cardiotoxicity of HL treatment has become a major cause of morbidity and mortality in survivors mainly related to the use of anthracycline. CASE REPORT: An HL, staged IIIB, was diagnosed in a 60-year-old man with no cardiovascular disease. During the first cycle of ABVD chemotherapy (Adriamycin; bleomycin; vinblastine; dacarbazine), near the end of the dacarbazine infusion, the patient presented a sudden cardiogenic shock characterized by a severe left ventricular systolic dysfunction...

Primary cardiac T cell lymphoma is an extremely rare condition with only a handful of biopsy-proven cases worldwide. We present a 62-year-old female presenting with nonspecific chest discomfort, shortness of breath, and anterolateral ST-elevation on electrocardiogram mimicking a ST-elevation myocardial infarction. Imaging revealed a cardiac mass and cardiac catheterization showed diffuse noncritical coronary disease with an occluded 2nd diagonal branch. Biopsy via minimally invasive cardiac surgery showed a pathologically proven diagnosis of primary cardiac T cell lymphoma...

Hydrogenated oils containing trans-fatty acids (TFA) are used to produce margarine and various processed foods. TFA affect serum lipid levels, fatty acid metabolism, and endothelial function. High TFA intake is linked to increased all-cause mortality, coronary heart disease mortality, and cardiovascular disease (CVD) incidence. Denmark was the first country to introduce a law that limited TFA content in food; this action led to lower CVD mortality. So far 7 European countries have followed this practice, in a few others the food industry voluntarily reduced TFA use...

BACKGROUND: The US Food and Drug Administration Adverse Event Reporting System (FAERS) is a global passive surveillance database that relies on voluntary reporting by health care professionals and consumers as well as required mandatory reporting by pharmaceutical manufacturers. However, the initial filers and comparative patterns for oral P2Y12 platelet inhibitor reporting are unknown. We assessed who generated original FAERS reports for clopidogrel, prasugrel, and ticagrelor in 2015...

OBJECTIVES: Bone marrow-derived cells (BMCs) have recently been identified to play a vital role in repairing damaged myocardium; however, it is not known whether or not mobilization of BMCs is involved in the pathogenesis of acute viral myocarditis (VMC). Thus, we analyzed the expression of CD45+CD34+VLA-4+ cells and vascular cell adhesion protein-1 (VCAM-1) in a murine model of acute VMC. METHODS: Male BALB/c mice were intraperitoneally infected with coxsackievirus B3 to establish acute VMC...

AIMS: We investigated the pathogenesis of MYH7-V878A and CACNA1C-A1594V mutations in a Chinese family with hypertrophic cardiomyopathy. METHODS: Clinical, electrocardiographic (ECG), echocardiographic, and cardiac magnetic resonance (CMR) examinations of members of a Chinese family were followed by exon and boarding intron analyses of 96 genes in the proband using second-generation sequencing. We confirmed the mutations by bidirectional Sanger sequencing in the members and in 300 healthy controls...

OBJECTIVES: Predictive models for heart failure (HF) in heterogeneous populations have had limited success. We examined cardiac computed tomography angiography (CTA) predictors of HF or cardiovascular death (HF-CVD) in a prospective study of asymptomatic diabetics undergoing baseline assessment by CTA. METHODS: The subjects (n = 735, aged 55-74 years, 51.2% women) had no clinical history of cardiovascular disease at study entry. Coronary artery calcium (CAC) score, CTA-defined coronary atherosclerosis, cardiac chamber volumes, and clinical data were collected and late outcome events recorded over 8...

The increasing use of cardiovascular magnetic resonance (CMR) is based on its capability to perform biventricular function assessment and tissue characterization without radiation and with high reproducibility. The use of late gadolinium enhancement (LGE) gave the potential of non-invasive biopsy for fibrosis quantification. However, LGE is unable to detect diffuse myocardial disease. Native T1 mapping and extracellular volume fraction (ECV) provide knowledge about pathologies affecting both the myocardium and interstitium that is otherwise difficult to identify...

BACKGROUND: The optimal dosing of novel oral P2Y12 receptor platelet inhibitors such as prasugrel or ticagrelor is unclear and especially challenging in East Asians. We hypothesize that half-dose prasugrel and ticagrelor may be sufficient for long-term maintenance management in Korean patients with the acute coronary syndrome (ACS) compared with conventional dosages. DESIGN: HOPE-TAILOR (Half Dose of Prasugrel and Ticagrelor in Platelet Response after Acute Coronary Syndromes) is a prospective, randomized, open-label, blinded, endpoint (PROBE) single-center, clinical trial...

OBJECTIVES: To assess the clinical impact of impaired renal function (IRF), in "real-world" acute coronary syndrome (ACS) patients, receiving clopidogrel, prasugrel, or ticagrelor. METHODS: This was a prospective, observational, multicenter, cohort study of ACS patients undergoing percutaneous coronary interventions (PCI) with IRF (creatinine clearance <60 mL/min by Cockroft-Gault equation), who were recruited into the Greek Antiplatelet Registry (GRAPE). Patients were followed-up until 1 year for major adverse cardiovascular events (MACE; a composite of death, nonfatal myocardial infarction, urgent revascularization, and stroke) and BARC (Bleeding Academic Research Consortium) bleeding...

BACKGROUND: It has been suggested that collagen abnormalities of the mitral valve are present in patients with floppy mitral valve (FMV)/mitral valve prolapse (MVP). Genetic factors determining collagen synthesis and degradation have not been well defined in these patients. This study was undertaken to determine whether selective polymorphisms of matrix metalloproteinase-2 (MMP2) or transforming growth factor-β (TGFβ), with known or putative effects on collagen turnover, are more frequent in FMV/MVP...

OBJECTIVES: This study's aim was to evaluate the protective effects of salvianolate on contrast-induced nephropathy after primary percutaneous coronary intervention (PPCI) compared with normal saline (NS) hydration. METHODS: We enrolled patients with acute myocardial infarction who underwent PPCI in 3 centers in Shanghai. The patients were randomly assigned to the salvianolate group or the NS group. The incidence of CIN, the changes in renal function parameters, and the occurrence of adverse events after the procedure were compared between the 2 groups...

OBJECTIVES: The PLATO trial revealed superiority of ticagrelor over clopidogrel for the prevention of atherothrombotic events in patients with acute coronary syndrome. However, adverse events such as bleeding, dyspnea, and bradycardia were frequently reported, potentially leading to excess early ticagrelor discontinuation (ETD), later confirmed in the PEGASUS trial. We here evaluated the incidence and causes for ETD in a real-world patient cohort in a high-volume nonacademic percutaneous coronary intervention center in the Netherlands...

We describe the case of a 25-year-old athlete experiencing syncope during a 5-km running race. A thorough diagnostic workup reasonably excluded a cardiac disorder as the cause of syncope. The characterization of this episode of syncope as noncardiac appears to contradict the common belief that syncope during exercise has always a cardiac origin. Following a detailed history taking, it was revealed that the symptoms of the athlete started after a 180° turn of the route. This situation represents a setting relevant to a runner who stops suddenly after reaching the finish line and soon after experiences noncardiac syncope due to the abrupt cessation of muscle pump function of the lower limbs...

Oncologic emergencies can present either as a progression of a known cancer or as the initial presentation of a previously undiagnosed cancer. In most of these situations, a very high degree of suspicion is required to allow prompt assessment, diagnosis, and treatment. In this article, we review the presentation and management of cardiovascular oncologic emergencies from primary and metastatic tumors of the heart and complications such as pericardial tamponade, superior vena cava syndrome, and hyperviscosity syndrome...

OBJECTIVES: Detection of atrial fibrillation (AF) in post-cryptogenic stroke (CS) or transient ischemic attack (TIA) patients carries important therapeutic implications. METHODS: To risk stratify CS/TIA patients for later development of AF, we conducted a retrospective cohort study using data from 1995 to 2015 in the Stanford Translational Research Integrated Database Environment (STRIDE). RESULTS: Of the 9,589 adult patients (age ≥40 years) with CS/TIA included, 482 (5%) patients developed AF post CS/TIA...

BACKGROUND: It has been reported that coronary slow flow (CSF) is associated with acute myocardial infarction, ventricular tachycardia, ventricular fibrillation, and even sudden cardiac death. Although studies concerning the etiopathogenesis of CSF are scarce, diffuse atherosclerosis and endothelial dysfunction are thought to play important roles. It has been suggested that a high plasma thrombomodulin (TM) level seems to play an important role in the pathogenesis of atherosclerosis and endothelial dysfunction...
