ObjectiveTo examine whether psychological resilience and psychological distress serially mediate the association between fear of disease progression and quality of life (QoL) in patients with chronic heart failure (CHF).MethodsThis cross-sectional study enrolled 212 patients with CHF admitted between June 2023 and June 2025. Assessment tools included a demographic questionnaire, the Fear of Progr…

A massive international study could upend 40 years of heart attack treatment. Researchers found that beta blockers—routinely prescribed after uncomplicated heart attacks—offered no real benefit for patients whose heart function remained normal, despite being given to millions worldwide. Even more surprising, women taking the drugs faced a higher risk of death, repeat heart attack, or hospitalizat…

BackgroundAlthough magnesium acts as a natural calcium antagonist with theoretical cardioprotective effects, its clinical value in critically ill patients with acute myocardial infarction (AMI) remains controversial. This study aimed to evaluate the impact of intravenous magnesium sulfate on ICU mortality in this population, and to explore potential dose-response relationships and effect modifier…

For many people, ultrasound is something connected with hospital scans and medical imaging. Doctors commonly use ultrasound to look inside the body, examine organs, monitor pregnancies, or check blood flow. The technology has been used safely for decades because it relies on sound waves rather than radiation. Now, scientists are exploring a very different use […] The post Ultrasound May Improve B…

High blood pressure is one of the world’s most common health problems. Millions of people live with it every day, often without noticing symptoms until serious damage has already occurred. Over time, high blood pressure can place enormous stress on blood vessels, the heart, and the brain. This increases the risk of dangerous conditions such […] The post Hidden Blood Vessel ‘Pressure Sensor’ May P…

Drinking nitrate-rich beetroot juice may do more than support heart health — it could actually reshape the bacteria living in the mouth in ways that help lower blood pressure in older adults. In the largest study of its kind, researchers found that older people who drank concentrated beetroot juice twice daily for two weeks experienced noticeable blood pressure reductions, while younger adults di…

A large Swedish study is helping answer a question that has worried some athletes and doctors for years: can very high fitness increase the risk of an irregular heartbeat later in life? The answer appears to be yes, but only partly. The same study also suggests that the overall benefits of high fitness are much […] The post Very fit young men may face one heart risk appeared first on Knowridge Sc…

Heart rhythm diseases are among the most dangerous heart problems in the world. Every year, they affect millions of people and can lead to fainting, stroke, heart failure, or sudden cardiac death. These conditions happen when the electrical signals that control the heartbeat stop working properly. Instead of beating in a smooth and steady rhythm, […] The post Scientists Discover Hidden Cause of D…

A major new study from researchers at Cedars-Sinai has found that younger people who suffer sudden cardiac arrest are much more likely to have a genetic cause behind the condition than older adults. The findings suggest that genetic testing could help identify people at risk before a deadly event happens. The research was published in […] The post Scientists Find Strong Genetic Link Behind Sudden…

Most people think heart attacks are mainly caused by long-term problems such as smoking, obesity, high cholesterol, or lack of exercise. While these risk factors are extremely important, scientists are increasingly discovering that sudden outside events can also trigger heart attacks in vulnerable people. New research is helping doctors better understand how certain short-term stresses […] The po…

Abstract Introduction Migraine increases the risk of ischemic stroke and cardiovascular disease in women, potentially due to systemic vascular dysfunction. We investigated whether migraine is associated with increased aortic stiffness and impaired cardiac function as markers of macrovascular dysfunction in middle-aged women with ischemic stroke. Methods This cross-sectional study included three g…

Abstract Background The left ventricular epicardium is a common site of origin (SOO) among patients with idiopathic premature ventricular complexes (PVCs) undergoing catheter ablation procedures. Less is known about epicardial PVC ablation among patients with myocardial scarring. The objective of this paper is to report on the presence and impact of cardiac scar among patients with epicardial PVC…

A new study led by a team from the University of Ottawa takes a major step forward in understanding how a heart attack can dramatically reshape brain function and trigger neurological effects, from depression and anxiety to different types of cognitive decline.

A new Expert Consensus Decision Pathway by the American College of Cardiology (ACC) provides recommended strategies for improving postpartum care for individuals with and at risk for short- and long-term cardiovascular disease (CVD).
