Researchers evaluate risk factors and outcomes for young adults with familial hypercholesterolemia

Heart attacks among adults younger than 50 years of age are on the rise. In fact, the proportion of very young people has been increasing, rising by 2 percent each year for the last 10 years, according to a team of investigators a Brigham and Women's Hospital who are focused on studying heart attacks among young adults.

Imaging beyond routine angiography may be helpful in women with suspected MI and no obstructive CAD

A subset of women referred to the cardiac catheterization lab for suspected myocardial infarction thought to be due to a culprit artery are found to have no obstructive coronary artery disease by angiography.

Cellular mechanism blocking retina regeneration discovered

A discovery opens the possibility of one day restoring loss of vision by activating the retina's ability to regenerate.

Adoption of new rules drops readmission penalties against safety net hospitals

Readmission penalties against hospitals providing care to socioeconomically disadvantaged patients have dropped 14 percentage points under new rules adopted in 2019 that more equitably account for low-income populations being served, according to a new analysis led by UT Southwestern Medical Center and Harvard researchers.

Exploring novel strategies to heal damage after a heart attack

For people who survive a heart attack, the days immediately following the event are critical for their longevity and long-term healing of the heart's tissue.

Simple mobility test helps predict hospital readmission in elderly heart attack patients

Close to 20% of elderly adults who have suffered a heart attack will be readmitted to the hospital within 30 days. Performance on a simple mobility test is the best predictor of whether an elderly heart attack patient will be readmitted, a Yale-led study reports.

More care is needed for patients after kidney transplantations, reports research

Patients with chronic kidney disease, and dialysis patients especially, have a significantly higher cardiovascular morbidity and mortality than healthy people. Kidney transplantation is the best renal replacement therapy available.

New adhesive patch could help reduce post-heart attack muscle damage

Researchers have designed a new type of adhesive patch that can be placed directly on the heart and may one day help to reduce the stretching of heart muscle that often occurs after a heart attack.

Researchers show potential of biomimicry to grow prevascularized tissues for cardiac patches

A team led by Feng Zhao, associate professor of biomedical engineering at Michigan Technological University, recently published two new papers on best practices in engineering prevascularized tissues.

U of G study beginning to unravel mystery of hagfish’s zombie hearts

They are the scavengers of the deep and the dead. Hagfish are slimy bottom-dwellers that live off the carcasses of dead sea creatures and thrive in deep waters where oxygen is hard to come by. In fact, their hearts can keep on beating for 36 hours without any oxygen, making hagfish a champion among anoxia-tolerant fish.

Research: Pure omega-3 prescription drug significantly reduces the occurrence of ischemic events

Taking a high dose of icosapent ethyl--a pure and stable prescription form of the omega-3 fatty acid known as EPA--significantly reduces the occurrence of first, subsequent and total ischemic events, including heart attacks, strokes and related deaths, among people at high cardiovascular risk despite already being on statin therapy, according to research presented at the American College of Cardiology's 68th Annual Scientific Session.

Study shows ticagrelor is equally safe and effective as clopidogrel after heart attack

Patients given clot busters to treat a heart attack fared equally well if they were given the standard blood thinning medication clopidogrel versus the newer, more potent drug ticagrelor, according to research presented at the American College of Cardiology's 68thAnnual Scientific Session.

Study: Radial or femoral approaches for PCI are equal in terms of survival in heart attack patients

Doctors can use either an artery in the arm (the radial approach) or in the groin (the femoral approach) to safely perform percutaneous coronary intervention (PCI) on patients presenting with a heart attack, according to research presented at the American College of Cardiology's 68thAnnual Scientific Session. The research, which was stopped early, suggests the radial and femoral approach are equivalent in terms of the risk of death at 30 days.

Study sheds light on the optimal timing of coronary angiography in NSTEMI patients

In patients resuscitated after cardiac arrest who do not show evidence of the type of heart attack known as ST-segment elevation myocardial infarction (STEMI), receiving immediate coronary angiography did not improve survival at 90 days compared to waiting a few days before undergoing the procedure, based on findings presented at the American College of Cardiology's 68thAnnual Scientific Session.

Radial and femoral approach for PCI achieve similar results in terms of survival

Doctors can use either an artery in the arm or in the groin to safely perform percutaneous coronary intervention on patients presenting with a heart attack, according to research presented at the American College of Cardiology's 68th Annual Scientific Session.

Light physical activity may lower risk of cardiovascular disease in older women

Light physical activity such as gardening, strolling through a park, and folding clothes might be enough to significantly lower the risk of cardiovascular disease among women 63 and older, a new study has found.

Heat-induced heart attack risk on the rise, study shows

Heart attack, or myocardial infarction, is the number one cause of death worldwide. A study published in the European Heart Journal by scientists at Helmholtz Zentrum München and colleagues from a range of other Bavarian institutions shows that the risk of suffering a heat-induced heart attack has increased significantly in recent years.

Exosomes are key to SOS signal that the heart muscle sends out after heart attack, study reveals

Human cells shed exosomes. These tiny extracellular, membrane-bound vesicles can carry cargo for cell-to-cell communication, ferrying diverse loads of proteins, lipids or nucleic acids.

Interdisciplinary medication education improves patient outcomes, reduces hospital readmissions

Patients understanding their medications and taking them as instructed are important parts of improving the care and outcomes of heart attack patients, as well as potentially reducing avoidable readmissions, according to research presented at the ACC Quality Summit in New Orleans.
