Context: Androgen deprivation therapy (ADT) for prostate cancer (PCa) is associated with increased cardiovascular mortality and sudden cardiac death, with some events occurring early after initiation of ADT. Testosterone levels are inversely associated with corrected QT (QTc) interval duration; therefore, prolongation of QTc duration could be responsible for some of these events during ADT. Objective: To evaluate changes in QTc duration during ADT. Design and Interventions: A 6-month prospective cohort study that enrolled men with PCa about to undergo ADT (ADT group) and a control group of men who previously underwent prostatectomy for PCa and never received ADT (non-ADT group)...

OBJECTIVE: A prolonged QTc (LQT) is a surrogate for the risk of torsade de pointes (TdP). QTc interval duration is influenced by sex hormones: oestradiol prolongs and testosterone shortens QTc. Drugs used in the treatment of breast cancer have divergent effects on hormonal status. METHODS: We performed a disproportionality analysis using the European database of suspected adverse drug reaction (ADR) reports to evaluate the reporting OR (ROR χ2 ) of LQT, TdP and ventricular arrhythmias associated with selective oestrogen receptor modulators (SERMs: tamoxifen and toremifene) as opposed to aromatase inhibitors (AIs: anastrozole, exemestane and letrozole)...

Nonalcoholic fatty liver disease (NAFLD) is a common, progressive liver disease that affects up to one-quarter of the adult population worldwide. The clinical and economic burden of NAFLD is mainly due to liver-related morbidity and mortality (nonalcoholic steatohepatitis, cirrhosis or hepatocellular carcinoma) and an increased risk of developing fatal and nonfatal cardiovascular disease, chronic kidney disease and certain types of extrahepatic cancers (for example, colorectal cancer and breast cancer). Additionally, there is now accumulating evidence that NAFLD adversely affects not only the coronary arteries (promoting accelerated coronary atherosclerosis) but also all other anatomical structures of the heart, conferring an increased risk of cardiomyopathy (mainly left ventricular diastolic dysfunction and hypertrophy, leading to the development of congestive heart failure), cardiac valvular calcification (mainly aortic-valve sclerosis), cardiac arrhythmias (mainly atrial fibrillation) and some cardiac conduction defects...

Significant advances in cancer treatment have resulted in decreased cancer related mortality for many malignancies with some cancer types now considered chronic diseases. Despite these improvements, there is increasing recognition that many cancer patients or cancer survivors can develop cardiovascular diseases, either due to the cancer itself or as a result of anticancer therapy. Much attention has focused on heart failure; however, other cardiotoxicities, notably cardiac rhythm disorders, can occur without underlying cardiomyopathy...

INTRODUCTION: Radical surgical treatment is the preferred action for patients with early-stage non-small cell lung cancer (NSCLC). Qualification for surgical treatment should consider a risk associated with the effect of comorbidities on the general condition of the patient. The aim of this article was an attempt to identify the risk factors for postoperative complications in patients treated for NSCLC, with a special focus on the coexisting diseases. METHODS: A total of 400 patients with NSCLC were included in this retrospective study...

Exposure to particulate matter (PM) leads to kinds of cardiopulmonary diseases, such as asthma, COPD, arrhythmias, lung cancer, etc., which are related to PM-induced inflammation. We have found that PM2.5 (aerodynamics diameter <2.5 µm) exposure induces inflammatory response both in vivo and in vitro. Since the toxicity of PM is tightly associated with its size and components, PM1 (aerodynamics diameter <1.0 µm) is supposed to be more toxic than PM2.5 . However, the mechanism of PM1 -induced inflammation is not clear...

PURPOSE OF REVIEW: There is growing awareness of the link between oncology treatments and cardiovascular (CV) complications. This has led to the development of cardio-oncology, a specialty aimed at managing CV risk and disease in cancer patients and survivors. Cardiac arrhythmias are potential adverse CV complications of cancer treatments; however, these cardiotoxicities are often underappreciated due to the uncertain arrhythmogenic mechanisms of various chemotherapeutic agents. RECENT FINDINGS: Chemotherapeutic agents can induce arrhythmias via direct electrophysiological effects on ion channels or intracellular signaling pathways, or indirectly from cardiac tissue damage...

The current arsenal of cancer chemotherapy is broad and rapidly expanding and includes conventional cytotoxic agents and targeted and immune-based therapies. As cancer survival rates have improved, the acute and latent cardiotoxicities of chemotherapy have emerged as important contributors to morbidity and mortality in cancer survivors. All chemotherapeutic agents have the potential for cardiac complications, with manifestations ranging from subclinical left ventricular dysfunction and asymptomatic QT prolongation, to congestive heart failure, myocardial ischemia, myocarditis, arrhythmia, and sudden cardiac death...

Ablation is a common procedure for treating patients with cancer, cardiac arrhythmia, and other conditions, yet it can cause collateral injury to the respiratory diaphragm. Collateral injury can alter the diaphragm's properties and/or lead to respiratory dysfunction. Thus, it is important to understand the diaphragm's physiologic and biomechanical properties in response to ablation therapies, in order to better understand ablative modalities, minimize complications, and maximize the safety and efficacy of ablative procedures...

OBJECTIVES: The Italian VATS Group database was accessed to evaluate whether preoperative and intraoperative factors may affect the safety of lymphadenectomy (LA) during video-assisted thoracic surgery lobectomy. METHODS: All video-assisted thoracic surgery lobectomy procedures performed between 1 January 2014 and 30 March 2017 for non-small-cell lung cancer with cN0 or cN1 disease were identified in the database. LA safety was evaluated based on intraoperative (operative time, bleeding and conversion rate) and postoperative (30-day morbidity and mortality, chest drain duration and length of stay) outcomes and was correlated with the number of resected lymph nodes and the rates of nodal upstaging...

Transient receptor potential melastatin member 4 (TRPM4), a non-selective cation channel, mediates cell membrane depolarization in immune response, insulin secretion, neurological disorders, and cancer. Pathological variants in TRPM4 gene have been linked to several cardiac phenotypes such as complete heart block (CHB), ventricular tachycardia, and Brugada syndrome (BrS). Despite recent findings regarding the functional implications of TRPM4 in cardiac diseases, the molecular and cellular mechanisms leading to altered conduction are poorly understood...

While inhibition of phosphoinositide 3-kinase (PI3K) is an emerging strategy in cancer therapy, we and others have reported that this action can also contribute to drug-induced Q-T prolongation and arrhythmias by increasing cardiac late sodium current (INaL). Previous studies in mice implicate the PI3K-α isoform as the major effector of the INaL action. Here, we have determined the effects of new anticancer drugs targeting specific PI3K isoforms on INaL and action potentials (APs) in mouse cardiomyocytes and CHO cells...

BACKGROUND: Thoracic surgery for lung resection is associated with a high incidence of postoperative pulmonary complications. Controlled ventilation with a large tidal volume has been documented to be a risk factor for postoperative respiratory complications after major abdominal surgery, whereas the use of low tidal volumes and positive end-expiratory pressure (PEEP) has a protective effect. OBJECTIVE: To evaluate the effects of ventilation with low tidal volume and PEEP on major complications after thoracic surgery...
