UPMC researchers shine light on common heart complication after lung transplantation

(University of Pittsburgh Schools of the Health Sciences) Cardiac arrhythmia is a common complication following lung transplantation, and one that has a significant negative impact on long-term patient survival.

Conclusions: Even with ovarian conservation, hysterectomy is associated with an increased long-term risk of cardiovascular and metabolic conditions, especially in women who undergo hysterectomy at age ≤35 years. If these associations are causal, alternatives to hysterectomy should be considered to treat benign gynecologic conditions.

Purpose of review The current article provides a concise summary of the possibilities and limitations of genotype-based risk stratification of cardiac arrhythmias. We will outline the most important findings of the recent years in the light of their chronological and conceptual development. Recent findings Genotype–phenotype association studies in families with single-gene disorders as well as in the general population led to the discovery of several DNA variants significantly associated with the risk of sudden death or life-threatening arrhythmias. In genetic (monogenic) diseases, the disease-causing mutations ...

Purpose of review Atrial fibrillation is a common cardiac arrhythmia with a high morbidity and mortality affecting 34 million worldwide. Current therapies are inadequate and often fail to directly address molecular mechanisms of the disease. In this review, we will provide an overview of recent advances in our understanding of the genetic underpinnings of atrial fibrillation. Recent findings Large-scale genetic association studies have more than doubled the number of genetic loci associated with atrial fibrillation during the last year. Studies examining how genes at or near these loci can affect the pathogenesis of a...

The relationship of epicardial fat and cardiac arrhythmias has been described in many studies. The association of the amounts of epicardial fat and the characteristics of electrocardiogram (ECG) remains unclear. The purpose of this study was to elucidate the association between the amounts of epicardial fat and the characteristics of ECG.

AbstractPurpose of ReviewThere 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 FindingsChemotherapeutic agents can induce arrhythmias via direct electrophysiological effects on ion channels or intracellular signal...

Obstructive sleep apnea syndrome (OSAS) is defined by recurrent episodes of significant reduction or absence of the oro-nasal airflow during sleep, in the presence of thorax and abdominal movements and snoring. The pathophysiological consequences of intermittent hypoxia determined by OSAS are represented by systemic inflammation, the release of free oxygen radicals and activation of the sympathetic nervous system. Cardiac arrhythmias are a frequent comorbidity in patients with OSAS.

Sudden cardiac death (SCD) in athletes is a rare but tragic complication of a number of cardiovascular diseases. Inherited causes such as the structural and arrhythmogenic genetic heart conditions are often found or suspected to be the underlying cause of death at post mortem examination. Physical activity and intense exercise may trigger cardiac arrhythmias in individuals with these conditions leading to SCD. Prevention and treatment strategies include individual athlete management strategies, coupled with public health measures such as universal cardiopulmonary resuscitation (CPR) training and availability of automatic e...
