Heart

To diagnose heart conditions including heart attacks and heart rhythm disturbances, clinicians typically rely on 12-lead electrocardiograms (ECGs) -- complex arrangements of electrodes and wires placed around the chest and limbs to detect the heart's electrical activity. But these ECGs require specialized equipment and expertise, and not all clinics have the capability to perform them.

A new small study has revealed the impact of obesity on muscle structure in patients having a form of heart failure called heart failure with a preserved ejection fraction (HFpEF). A new small study led by Johns Hopkins Medicine researchers and published July 25th in the journal Nature Cardiovascular Research has revealed the impact of

Higher levels of urinary metals such as cadmium, tungsten, uranium, cobalt, copper and zinc are linked to increased cardiovascular disease and mortality in a racially and ethnically diverse U.S. population, according to a new study. Higher levels of urinary metals such as cadmium, tungsten, uranium, cobalt, copper and zinc are linked to increased cardiovascular disease

Having high blood pressure, specifically high diastolic blood pressure, was linked to a slightly higher odds of ever having migraine in female participants, according to a new study. Diastolic pressure is when the heart is resting between beats. However, the study did not find an increased risk between other cardiovascular risk factors and migraine. Having

The innermost layer of blood vessels is formed by endothelial cells, which in turn play a role in the development of diseases of the cardiovascular system. Human endothelial cells are therefore required for the 'in vitro' investigation of the causes of these diseases. Researchers have now established a highly efficient, cost-effective and reproducible way to

A novel study co-authored by a heart failure cardiologist demonstrates the effectiveness of a newly developed scoring system in identifying patients with Heart Failure with Preserved Ejection Fraction (HFpEF). A novel study co-authored by a heart failure cardiologist at University Hospitals Harrington Heart & Vascular Institute, demonstrates the effectiveness of a newly developed scoring system

If current guidelines for cholesterol and high blood pressure treatment remain unchanged, a newly unveiled heart risk calculator would render 16 million people ineligible for preventive therapy. Loss of eligibility for cholesterol and blood pressure medicines could lead to 107,000 more heart attacks and strokes over 10 years but may reduce new diabetes cases by

Researchers reveal the impact of transthyretin protein levels on heart disease risk. Physician-scientists from the University of Alabama at Birmingham Marnix E. Heersink School of Medicine have uncovered significant findings regarding the impact of transthyretin, or TTR, protein levels on heart disease risk. The study, recently published in Nature Communications, explores how variations in TTR

Scientists have developed the R-EDByUS score, a new model predicting neurological outcomes in out-of-hospital cardiac arrest patients using prehospital data only. The model allows for rapid decision-making upon hospital arrival, enhancing patient care and resource allocation. This innovation marks a significant advancement in emergency medical treatment. When it comes to treating cardiac arrest, acting quickly

A new mathematical method, validated with experimental animal data, provides a fast, reliable and minimally invasive way of determining how to treat critical blood pressure changes during surgery or intensive care. If patients receiving intensive care or undergoing major surgery develop excessively high or low blood pressures, they could suffer severe organ dysfunction. It's not

3D-printed blood vessels, which closely mimic the properties of human veins, could transform the treatment of cardiovascular diseases. Strong, flexible, gel-like tubes -- created using a novel 3D printing technology -- could improve outcomes for heart bypass patients by replacing the human and synthetic veins currently used in surgery to re-route blood flow, experts say.

Personalized text messages effectively promoted increased physical activity for patients after significant heart events -- such as a heart attack or surgery -- but those effects later diminished. Researcher say the results show incredible promise for simple, low cost interventions delivered through mobile technology and their potential to help prevent secondary cardiovascular events in patients.
