Middle-aged athletes at low risk for sudden cardiac arrest while exercising — Physically active middle-aged adults have low risk of sudden cardiac arrest – Sudden cardiac arrest during sports activities is relatively low among physically active middle-aged adults, and older people can exercise without worrying about triggering a heart rhythm disturbance, revealed by American researchers.
Researchers develop first minimally invasive gene therapy procedure to treat heart rhythm disorders by transforming ordinary heart muscle cells into specialized rhythm-keeping cells, potentially eliminating future need for electronic pacemakers – Cardiologists at the Cedars-Sinai Heart Institute have developed a minimally invasive gene transplant procedure that changes unspecialized heart cells into “biological pacemaker” cells that keep the heart steadily beating.
COPD patients at significantly higher risk of heart failure – Patients with chronic obstructive pulmonary disease (COPD) have a complication to worry about is heart failure. A new study found the prevalence of heart failure is significantly higher in patients with COPD compared to the rest of the study population. They also found that the risk was especially high among African-American patients with COPD.
High consumption of fish oil may benefit cardiovascular health, Pitt public health finds – Eating fish in amounts comparable to those of people living in Japan seems to impart a protective factor that wards off heart disease, revealed by researchers.
Baby hearts need rhythm to develop correctly – To develop correctly, baby hearts need rhythm even before they have blood to pump. “We have discovered that mechanical forces are important when making baby hearts,” said Mary Kathryn Sewell-Loftin, a Vanderbilt graduate student working with a team of Vanderbilt engineers, scientists and clinicians attempting to grow replacement heart valves from a patient’s own cells.
Researchers discover how heart arrhythmia occurs – Researchers have discovered the fundamental biology of calcium waves in relation to heart arrhythmias. The findings published this month in the January 19 edition of Nature Medicine outlines the discovery of this fundamental physiological process that researchers hope will one day help design molecularly tailored medications that correct the pathophysiology.
Findings Not Supportive of Women-Specific Chest Pain Symptoms in Heart Attack Diagnosis – Using chest pain characteristics (CPCs) specific to women in the early diagnosis of acute myocardial infarction (AMI, heart attack) in the emergency department does not seem to be supported by the findings of a study published by JAMA.
High salt levels in common medicines put patients at increased risk of cardiovascular events — Researchers call for salt content of medicines to be labeled in same way as foods – Taking the maximum daily dose of some medicines would exceed the recommended daily limits for sodium, without any additional dietary intake. Public should be warned about the potential dangers of high sodium intake from prescribed medicines, reveals new study.
Study may impact guidelines for mitral valve surgery for severe ischemic mitral regurgitation — New findings showing mitral valve replacement may be more effective than mitral valve repair reported at AHA Scientific Sessions 2013 and in New England Journal of Medicine – The Cardiothoracic Surgical Trials Network (CTSN), whose Data and Clinical Coordinating Center is at Icahn School of Medicine at Mount Sinai, is reporting for the first time evidence on whether or not there is any significant difference between the two current surgical approaches to treat patients with severe ischemic mitral regurgitation — mitral valve repair and mitral valve replacement.
Disrupting an antioxidant pathway prevents heart disease caused by reductive stress – Researchers have found that deficiency of an antioxidant response protein called nuclear erythroid-2 like factor-2 (Nrf2) delays or prevents hypertrophic cardiomyopathy, a type of a heart failure in which the heart muscle grows abnormally thick.
