BACKGROUND: An association between atrial fibrillation (AF) and risk of cancer has been suggested in several studies, including prospective cohort studies. However, the magnitude and the temporal nature of this association remain unclear. METHODS: Data from two large prospective population-based case-control studies, the Molecular Epidemiology of Colorectal Cancer (MECC, n = 8,383) and the Breast Cancer in Northern Israel Study (BCINIS, n = 11,608), were used to better understand the nature and temporality of a possible association between cancer diagnosis and AF events before and after cancer diagnosis...

We report a case of increased prothrombin time-international normalized ratio (PT-INR) when crizotinib and warfarin were co-administered. A 74-year-old Japanese woman presented to the hospital with dyspnea, and was diagnosed with anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer (NSCLC). Three years after surgical resection of the tumor, the patient started crizotinib because of the recurrence of NSCLC. She received 2 mg/day warfarin due to a medical history of cerebral infarction and chronic atrial fibrillation...

Consuming a Mediterranean diet rich in minimally processed plant foods has been associated with a reduced risk of developing multiple chronic diseases and increased life expectancy. Data from several randomized clinic trials have demonstrated a beneficial effect in the primary and secondary prevention of cardiovascular disease, type 2 diabetes, atrial fibrillation and breast cancer. The exact mechanism by which an increased adherence to the traditional Mediterranean diet exerts its favorable effects is not known...

The quality-adjusted life year (QALY) and incremental cost-effectiveness ratio (ICER) are important concepts in cost-effectiveness analysis, which is becoming increasingly important in Japan. QALY is used to estimate quality of life (QOL) and life years, and can be used to compare the efficacies of cancer and cardiovascular treatments. ICER is defined as the difference in cost between treatments divided by the difference in their effects, with a smaller ICER indicating better cost-effectiveness. Here, we present a review of cost-effectiveness analyses in Japan as well other countries...

In this second part of a 2-part review, we will review cancer or cancer therapy-associated systemic and pulmonary hypertension, QT prolongation, arrhythmias, pericardial disease, and radiation-induced cardiotoxicity. This review is based on a MEDLINE search of published data, published clinical guidelines, and best practices in major cancer centers. Newly developed targeted therapy can exert off-target effects causing hypertension, thromboembolism, QT prolongation, and atrial fibrillation. Radiation therapy often accelerates atherosclerosis...

Ischaemic stroke is rare in premenopausal women but risk increases with advancing age and doubles in the ten years following the menopause. Up to the age of 75 years men have a 25% higher risk of suffering a stroke compared with women. However, the increased life expectancy of women ultimately results in a higher overall incidence. Twice as many women die from stroke compare with breast cancer. Women with cerebrovascular disease are more likely to present with atypical symptoms than men. Altered mental status (including unresponsiveness, confusion and behavioural change) is the most common nonconventional symptom, and is reported by 23% of women compared with 15% of men...

OBJECTIVE: There is suggestive evidence linking hypoglycemia with cardiovascular disease, but few data have been collected in a community-based setting. Information is lacking on individual cardiovascular outcomes and cause-specific mortality. RESEARCH DESIGN AND METHODS: We conducted a prospective cohort analysis of 1,209 participants with diagnosed diabetes from the Atherosclerosis Risk in Communities (ARIC) study (analytic baseline, 1996-1998). Severe hypoglycemic episodes were identified using first position ICD-9 codes from hospitalizations, emergency department visits, and ambulance calls through 2013...

Epidemiogical evidence has shown that the incidence of atrial fibrillation in tumor patients is higher than non-tumor patients and general population. The potential risk factors predisposing tumor patients to atrial fibrillation include advanced age, comorbidities, direct anatomic local occupying effect of tumors in the heart or adjacent organs, paraneoplastic manifestations of some tumors, tumor-induced dys-regulation of metabolism, radio-, bio- and chemo-therapeutics, disturbance of autonomous nerve system because of physical pain and psychological sufferings, chronic inflammation typical of most tumors, and surgical interventions among others...

Enzalutamide, a novel, oral androgen receptor antagonist used for the treatment of metastatic, castration-resistant prostate cancer, has been shown to improve overall and progression-free survival, prolong time to initiation of chemotherapy, reduce skeletal-related events, and carry a favorable adverse effect profile. Metastatic prostate cancer is a disease of older men, a population with an increased incidence of medical comorbidities warranting anticoagulation. Prostate cancer itself, along with some of its therapies, is also prothrombotic...

We report a case of a 57-year-old man who presented with an episode of syncope resulting in an accident. On presentation, he was found to have atrial fibrillation (AF). A brain imaging done to exclude intracranial hemorrhage revealed a brain tumor instead. Recently, AF has been used as a marker for occult cancer. Thus, we hypothesize that AF in our patient was a result of the existing brain tumor and not simply a coincidence. AF may help in diagnosing brain tumors in asymptomatic or oligosymptomatic patients at an early stage, decreasing mortality and morbidity significantly...

BACKGROUND: Atrial fibrillation (AF) is the most frequent arrhythmia, and its prevalence is increasing with aging. We aimed to compare the long-term outcome data of patients < 65 years vs. ≥ 65 years who underwent catheter ablation (CA) for drug-refractory AF. METHODS: Consecutive patients with primary pulmonary vein isolation performed between March 2001 and December 2011, and those who completed a five-year of follow-up were divided into two groups: patients aged < 65 years into group 1, and patients aged ≥ 65 into group 2...

Cancer is a known hypercoagulable state that leads to an increased risk of venous thromboembolism (VTE). Low molecular weight heparin remains the preferred anticoagulant for VTE in patients with cancer over vitamin K antagonist. However, the preferred anticoagulant in prevention of stroke and systemic embolism in atrial fibrillation (AF) in patients with cancer has yet to be determined. The direct oral anticoagulants (DOACs) are increasingly being utilized; however their role in cancer has only recently been investigated...
