While a baby was still attached via the umbilical cord, doctors attached a pacemaker to the baby's heart

Fri, 02/16/2018 - 14:26
Researchers completed the first-ever EXIT (Ex Utero Intrapartum Treatment) to ventricular pacing procedure. The patient, a 36-week fetus with complete atrioventricular block and cardiac dysfunction, was at high risk of pre-term death. While attached to its mother via umbilical cord, the baby received a temporary pacemaker, which stabilized its dangerously low and irregular heart rate and ensured enough blood flow from the heart to the rest of its body for delivery.

Rapid pollution increases may be as harmful to the heart as absolute levels

Thu, 02/15/2018 - 18:03
Rapid increases in pollution may be as harmful to the heart as sustained high levels, according to new research. The authors urgently call for confirmatory studies as even residents of clean air cities could be at risk.

Hearing loss is common after infant heart surgery

Thu, 02/15/2018 - 14:46
Children who have heart surgery as infants are at risk for hearing loss, coupled with associated risks for language, attention and cognitive problems, by age four. In a cohort of 348 preschoolers who survived cardiac surgery, researchers found hearing loss in about 21 percent, a rate 20 times higher than is found in the general population. This underscores the importance of early hearing evaluations in young children who undergo heart surgery.

Cardiac macrophages found to contribute to a currently untreatable type of heart failure

Wed, 02/14/2018 - 15:02
Investigators have discovered, for the first time, that the immune cells called macrophages contribute to a type of heart failure for which there currently is no effective treatment.

Shorter time between first medical contact to PCI in heart patients linked to saving lives

Tue, 02/13/2018 - 22:34
Heart experts are calling for immediate action following new research in the European Heart Journal that shows every minute counts for patients who suffer the most severe type of heart attack. The study shows numbers of deaths rise steadily and rapidly the longer the time between patients' first contact with a medical professional and when they are treated in hospital with percutaneous coronary intervention (PCI) to insert a balloon catheter to widen blocked arteries and restore blood flow to the heart.

Newly discovered gene may protect against heart disease

Tue, 02/13/2018 - 18:35
Scientists have identified a gene that may play a protective role in preventing heart disease. Their research revealed that the gene, called MeXis, acts within key cells inside clogged arteries to help remove excess cholesterol from blood vessels.

What is a 'normal' blood pressure response during exercise testing?

Tue, 02/13/2018 - 15:43
New data suggest that the guidelines used to evaluate an individual's peak blood pressure response during cardiopulmonary exercise testing, which were last updated in 1996 and help doctors screen for hypertension and cardiovascular disease, may need to be revised.

Molecular mechanisms crucial for new approach to heart disease therapy mapped

Tue, 02/13/2018 - 12:04
Scientists have reprogrammed ordinary cells called fibroblasts into new and healthy heart muscle cells, and recorded changes that appear to be necessary for this reprogramming.

Obesity, other risks play large role in sudden cardiac arrest among the young

Mon, 02/12/2018 - 17:00
Obesity and other common cardiovascular risk factors may play a greater role in sudden cardiac arrest among younger people than previously recognized, underscoring the importance of earlier screening, a new study has found.

Biomarker predicts success of Afib treatment

Mon, 02/12/2018 - 08:44
Researchers report successful use of heart imaging to predict the benefit or futility of catheter ablation, an increasingly popular way to treat atrial fibrillation, a common heart rhythm disorder.

Survivors of childhood heart defects may have higher risk of premature dementia

Mon, 02/12/2018 - 08:43
Children born with heart defects are more likely to survive into old age because of improved early treatments, but they may be more likely to develop early-onset dementia than people born without heart defects.

Stroke risk factors unique to women identified

Thu, 02/08/2018 - 08:48
Investigators are exploring the effects of potential risk factors that are unique to women, including hormone levels, hormone therapy, hormonal birth control, pregnancy and time of menarche and menopause.

Potential treatment for diastolic dysfunction in heart failure

Wed, 02/07/2018 - 16:40
Researchers have identified a potential treatment target for patients with a common type of heart failure. In a new study, the researchers tested the effect of an investigational drug called givinostat in treating diastolic dysfunction, which is a heart relaxation abnormality that contributes to heart failure with preserved ejection fraction (HFpEF).

Children with heart failure from dilated cardiomyopathy are seeing a dramatic improvement in outcomes in recent years

Mon, 02/05/2018 - 16:16
New research has shown that for children with heart failure from dilated cardiomyopathy there has been a dramatic improvement in outcomes of medical management in the past few years. The study also shows that significantly fewer of these patients die from heart disease.

Traffic noise-induced harm to cardiovascular system

Mon, 02/05/2018 - 14:11
Noise may disrupt the body on the cellular level in a way that increases the risk of common heart disease risk factors, according to a new review that examined the underlying mechanisms that may lead to noise-induced heart disease. The review is in response to growing evidence connecting environmental noise, including from road traffic and aircrafts, to the development of heart disease, such as coronary artery disease, arterial hypertension, stroke and heart failure.
