Researchers have discovered how to predict some cardiac arrhythmias several steps before they even occur. It’s a finding that could lead to an improved cardiac device, with equipment designed to detect when arrhythmias are about to occur and then act to prevent them.
People with high blood pressure may need to lower it much more than previously thought, according to the recently announced results of a major study. A heart health expert discusses the implications.
A sticky, protein-rich gel created by Johns Hopkins researchers appears to help stem cells stay on or in rat hearts and restore their metabolism after transplantation, improving cardiac function after simulated heart attacks, according to results of a new study.
Scientists at The Ohio State University Dorothy M. Davis Heart and Lung Research Institute have identified a new genetic cause for congenital heart arrhythmia. The mechanism is due to defects in the regulation of the primary sodium channel, which controls the flow of sodium ions across the heart cell membrane.
Blood tests in obese African-American teenage girls reveal immune system changes which ‘prime the system’ to develop cardiovascular disease later in life.
Loyola University Chicago is among the centers participating in a landmark clinical trial that has found that more intensive management of high blood pressure reduces heart disease rates and saves lives.
A cardiovascular team at University of Utah Hospital has successfully performed a first-in-the-world heart procedure on a 72-year-old attorney after suffering a large heart attack. Amit N. Patel, M.D. M.S., director of clinical regenerative medicine and associate professor of surgery at University of Utah Health Care, was the first physician to perform an emerging heart procedure where cardiac matrix is directly injected into a damaged heart. This is the first clinical trial to be approved by the U.S. Food and Drug Administration (FDA) for matrix therapy of the heart.
Scientists have evidence that Popeye was right: Spinach makes you stronger. But it’s the high nitrate content in the leafy greens — not the iron — that creates the effect. Building on a growing body of work that suggests dietary nitrate improves muscle performance in many elite athletes, researchers at Washington University School of Medicine in St. Louis found that drinking concentrated beet juice — also high in nitrates — increases muscle power in patients with heart failure.
Drugs commonly used to treat high blood pressure, and prevent heart attacks and strokes, are associated with significantly worse cardiovascular outcomes in hypertensive African Americans compared to whites, according to a new comparative effectiveness research study led by researchers in the Department of Population Health at NYU Langone Medical Center, published in the Journal of the American College of Cardiology.
Dominic Raj, M.D., director of the Division of Renal Diseases and Hypertension and professor of medicine at the George Washington University, participated in a multi-site landmark study finding cardiovascular disease morbidity is significantly reduced through intensive management of high blood pressure.
Lower blood pressure target of 120 mm Hg greatly reduces cardiovascular complications and deaths in older adults.
More intensive management of high blood pressure, below a commonly recommended blood pressure target, significantly reduces rates of cardiovascular disease, and lowers risk of death in a group of adults 50 years and older with high blood pressure.
A prospective longitudinal study of U.S. Marines suggests that reduced heart rate variability – the changing time interval between heartbeats – may be a contributing risk factor for post-traumatic stress disorder (PTSD). The findings are reported in the September 9 online issue of JAMA Psychiatry by researchers at the University of California, San Diego School of Medicine and Veterans Affairs San Diego Healthcare System.
In this week's New England Journal of Medicine, researchers report results of a trial showing the efficacy of a new enzyme-replacement therapy for lysosomal acid lipase deficiency. In an accompanying editorial, Daniel J. Rader, MD, chair of the department of Genetics in the Perelman School of Medicine at the University of Pennsylvania, notes that this first-ever hepatocyte-targeting therapy will be pivotal in treating this disease.
With the world’s elderly population expected to double by 2050, understanding how aging affects the body is an important focus for researchers globally. Cardiovascular disease, the No. 1 cause of death worldwide, often is associated with aging arteries that restrict blood flow. Now, University of Missouri researchers have identified an age-related cause of arterial dysfunction, a finding that could lead to future treatments for some forms of vascular disease.
Jefferson researchers showed that a simple questionnaire, evaluation and pulse-oximetry monitoring can lead to early detection of sleep apnea in patients hospitalized for congestive heart failure.
Scientists at The Ohio State University Davis Heart and Lung Research Institute have identified a new target they hope will help make the next drug discovery for patients with heart arrhythmias happen sooner. The key may reside in voltage-gated sodium channels, nanoscopic pores that control the flow of sodium ions across the heart cell membrane.
Exercise improves health in overweight and obese adults but can be hard to incorporate into a daily routine. New findings show that taking vitamin C supplements daily instead can have similar cardiovascular benefits as regular exercise in these adults.
Xian-Cheng Jiang, PhD, professor of cell biology at SUNY Downstate Medical Center, has led a study identifying a new approach for lowering "bad" lipids in blood circulation, a critical means to combat devastating cardiovascular diseases such as atherosclerosis.
Exercise training for patients with pulmonary hypertension was shown to be safe and to improve quality of life, according to an analysis by UT Southwestern Medical Center cardiologists of studies involving more than 400 participants.
