Genomics experts dispute nine genes linked to congenital heart condition

Geneticists and heart specialists around the world had previously reported 17 genes to cause long QT syndrome, a little-known inherited heart condition. However, the Clinical Genome Resource’s (ClinGen) expert panel has critically reevaluated the scientific evidence for all 17 reported genes, disputing nine of the genes and revealing only three of the genes to be definitively … Read more Genomics experts dispute nine genes linked to congenital heart condition

Brush your teeth to protect the heart

Brushing teeth frequently is linked with lower risks of atrial fibrillation and heart failure, according to a study published today in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC). Previous research suggests that poor oral hygiene leads to bacteria in the blood, causing inflammation in the body. Inflammation increases … Read more Brush your teeth to protect the heart

Researchers report first recording of a blue whale’s heart rate

Encased in a neon orange plastic shell, a collection of electronic sensors bobbed along the surface of the Monterey Bay, waiting to be retrieved by Stanford University researchers. A lunchbox-sized speck in the vast waters, it held cargo of outsized importance: the first-ever recording of a blue whale’s heart rate. This device was fresh off … Read more Researchers report first recording of a blue whale’s heart rate

Omega-3 shows protection against heart disease-related death, without prostate cancer risk

Should you take omega-3 pills? Or try to have two to servings of omega-3 rich fish a week, as the American Heart Association recommends? It may seem a bit murky if you follow headlines about nutrition and health. That’s why researchers at the Intermountain Healthcare Heart Institute continue to research the potential benefits and risks … Read more Omega-3 shows protection against heart disease-related death, without prostate cancer risk

Bionic pacemaker slows progression of heart failure

In the UK alone, around 900,000 people are living with heart failure and almost 1.4 million have survived a heart attack. After such an event, pacemakers are often fitted to either speed up the heart or to overcome electrical conduction problems between different chambers of the heart. There is no cure for heart failure; its … Read more Bionic pacemaker slows progression of heart failure

Cardiologists establish how e-cigarettes damage the brain, blood vessels and lungs

Cardiologists have issued a stark warning about the dangers of e-cigarettes, particularly for young people, as results of new research show the damage they cause to the brain, heart, blood vessels and lungs. The study, which is published in the European Heart Journal today (Wednesday), also identifies some of the mechanisms involved, for which there has been … Read more Cardiologists establish how e-cigarettes damage the brain, blood vessels and lungs

Cardiothoracic Imaging publishes special report on vaping

Radiology: Cardiothoracic Imaging has published a special report on lung injury resulting from the use of electronic cigarettes (e-cigarettes), or “vaping.” Authors Suhny Abbara, M.D., FACR, MSCCT and Fernando Uliana Kay, M.D., Ph.D., from the Department of Radiology at UT Southwestern Medical Center in Dallas, Texas, aim to raise awareness among radiologists and other medical professionals … Read more Cardiothoracic Imaging publishes special report on vaping

3D printing, bioinks create implantable blood vessels

A biomimetic blood vessel was fabricated using a modified 3D cell printing technique and bioinks, which were formulated from smooth muscle cells from a human aorta and endothelial cells from an umbilical vein. The result is a fully functional blood vessel with a dual-layer architecture that outperforms existing engineered tissue and brings 3D-printed blood vessels … Read more 3D printing, bioinks create implantable blood vessels

Developing electrically active materials to repair damaged hearts

When a heart attack occurs, muscle in the heart tissue can be scarred, interfering with electrical activity necessary for healthy heart function. Drug treatments are available that alleviate further damage, but these don’t lead to tissue regeneration. Using artificial materials to patch or rebuild damaged parts has been tried but only recently has work focused … Read more Developing electrically active materials to repair damaged hearts

Your heart’s best friend: Dog ownership associated with better cardiovascular health

Owning a pet may help maintain a healthy heart, especially if that pet is a dog, according to the first analysis of data from the Kardiozive Brno 2030 study. The study examines the association of pet ownership – specifically dog ownership – with cardiovascular disease risk factors and cardiovascular health. The results are published in Mayo Clinic Proceedings: Innovations, Quality … Read more Your heart’s best friend: Dog ownership associated with better cardiovascular health
