The incidence of coronary artery compression in children fitted with epicardial pacemakers may be slightly more common than previously believed. After reviewing patient records at Boston Children's Hospital, they advocate for stricter monitoring to identify patients at risk and prevent complications. The study was published in the journal HeartRhythm, the official journal of the Heart Rhythm Society and the Cardiac Electrophysiology Society.

Atrial fibrillation(AF) is an irregular and often rapid heart rate that can increase the risk of stroke, heart failure, and other heart-related complications. It's more common in older people, and as it happens, in people who are obese. But new research suggests that exercise can have a moderating effect on the risk of developing this problem.
The risk of atrial fibrillation was lower the more physically active a person was. This turned out to be especially true for people with obesity. The study was published in the European Journal of Preventive Cardiology.
A drug currently in clinical trials for treating symptoms of Parkinson's disease may someday have value for treating heart failure, according to results of early animal studies by Johns Hopkins Medicine researchers.
People infected with HIV are twice as likely to suffer from heart disease, research has found. Analysis of global figures reveals that HIV-associated cardiovascular disease has more than tripled in the past 20 years as more people are living longer with the virus. The greatest impact is in sub-Saharan Africa and Asia Pacific regions, with Swaziland, Botswana and Lesotho particularly affected.
A new research team is on a quest to collapse a tiny pocket between cardiac cells that can cause big problems. Called the perinexus, the structure spans only tenths of a millimeter all the space it needs to disrupt a person's heartbeat. The researchers were the first to identify the perinexus in humans. The study was published in Frontiers in Physiology.
Cumulative use of ritonavir-boosted darunavir, a contemporary protease inhibitor used to treat HIV, is associated with an increasing risk of cardiovascular disease, according to results from the D:A:D study.
By analyzing reported physical activity levels over time in more than 11,000 American adults, Johns Hopkins Medicine researchers conclude that increasing physical activity to recommended levels over as few as six years in middle age is associated with a significantly decreased risk of heart failure, a condition that affects an estimated 5 million to 6 million Americans. The same analysis found that as little as six years without physical activity in middle age was linked to an increased risk of the disorder.
Research from the University of Warwick indicates that taking a tablet a day can help treat cancer patients of a potentially deadly condition. People with cancer have an increased risk of developing blood clots, with roughly one in five experiencing venous thromboembolism (VTE) – either deep vein thrombosis (DVT) or pulmonary embolism (PE). Blood clots in the deep veins of the leg may travel to the lungs causing a pulmonary embolism. These two conditions are referred to as VTE – a dangerous and potentially deadly medical condition of which there are 10 million cases worldwide.
Patients with an abnormal heart rhythm that can leave them at a higher risk of suffering from stroke still need treatment even after their heart rhythm seems to have returned to normal, say researchers at the University of Birmingham.
Cardiovascular tissue engineering aims to treat heart disease with prostheses that grow and regenerate. Now, researchers from the University of Zurich, the Technical University Eindhoven and the Charité Berlin have successfully implanted regenerative heart valves, designed with the aid of computer simulations, into sheep for the first time.
Laws and policies that prohibit smoking in workplaces and other public areas appeared to significantly lower the risk of cardiovascular disease among a group of young adults who were followed over a 20-year span.
Following a heart attack, the parts of the heart muscle that die do not regenerate into new heart tissue and instead are replaced by scar tissue. Using rodent models, researchers at Baylor College of Medicine are looking for a means to genetically convert this scar tissue into muscle tissue at the cellular level, which could ultimately be a way to treat heart attack and heart failure patients. Their latest work was published in The Journal of Thoracic and Cardiovascular Surgery.
