Cardiology

Cardiovascular diseases cause one death every 33 seconds in America. Diagnosing these conditions, which account for approximately 20% of all deaths annually, can be difficult because the overlaying and natural fluorescence of cardiac tissue complicate diagnostic images.

U.S. adults with both hypertension and type 2 diabetes (T2D) face a significantly higher risk of all-cause and cardiovascular mortality compared to those with only one of these conditions—or neither, reports a new study from Columbia University Mailman School of Public Health.

A study led by a physician-scientist at the University of Arizona College of Medicine–Tucson’s Sarver Heart Center identified a drug candidate that appears to reverse the progression of a type of heart failure in mouse models, which could lead to expanded treatment options for humans. The results are published in the journal Cell Metabolism.

Experiencing food insecurity in early childhood is associated with worse heart health two decades later, especially higher Body Mass Index (BMI). But participation in the Supplemental Nutrition Assistance Program (SNAP) may significantly mitigate that risk, reports a long-term Northwestern Medicine study published in JAMA Cardiology.

An international team of researchers has discovered how cholesterol can disrupt the internal functioning of the heart by accumulating in the mitochondria of cardiomyocytes. They have also developed an experimental immunotherapy capable of reversing this process and restoring cellular energy production.

A new study in the European Heart Journal shows that people who develop type 1 diabetes in adulthood have an increased risk of cardiovascular disease and death, and that those diagnosed later in life do not have a better prognosis than those diagnosed earlier.

University of East Anglia scientists have developed cutting-edge MRI technology to diagnose a common heart problem more quickly and accurately than ever before.

A test commonly used to confirm a condition linked to high blood pressure is often inaccurate, causing doctors to skip treatment that might improve patients’ heart health, a new study says.

In patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI), stenting demonstrated improved long-term survival and fewer cardiac arrests at one year. The late-breaking data were presented today at the Society for Cardiovascular Angiography & Interventions (SCAI) 2025 Scientific Sessions.

‘No-touch’ vein harvesting significantly reduces the risk of graft failure up to three years after coronary artery bypass surgery compared with conventionally harvested vein grafts, finds a study from China published by The BMJ.
