Soft robots hug the heart to help pump blood

Soft robots hug the heart to help pump blood

Washington: An implantable soft-robotic device could help failing hearts pump blood by giving the organ gentle squeezes, mimicking the natural motion of cardiac muscle, a new study reveals. more

Patients treated with drug eluting stents do not live longer than patients treated with bare metal stents: Study

Patients treated with drug eluting stents do not live longer than patients treated with bare metal stents: Study

Rome: New generation drug eluting stents (new DES) did not outshine contemporary bare metal stents (BMS) as they were expected to, in a surprise finding of the largest randomized stent trial to date. The study is published in The New England Journal of Medicine. more

Researchers develop model to predict sudden cardiac death

Researchers develop model to predict sudden cardiac death

Washington: Researchers from Emory’s Rollins School of Public Health have developed a sudden cardiac death (SCD) predictive model that can help identify and prevent the disease in more

Functional heart muscle regenerated in decellularized human hearts

Functional heart muscle regenerated in decellularized human hearts

Washington: Massachusetts General Hospital (MGH) researchers have taken some initial steps toward the creation of bioengineered human hearts using donor hearts stripped of components that would generate an immune response and cardiac muscle cells generated from induced pluripotent stem cells (iPSCs), which could come from a potential recipient. more

Using Western BP guidelines may up stroke risk in Asian patients

Using Western BP guidelines may up stroke risk in Asian patients

London: European and North American blood pressure guidelines, issued last year, may actually increase the stroke risk if adapted for Asian patients, particularly the elderly, experts have warned. more

Doctors use virtual reality device to treat blocked coronary artery

Doctors use virtual reality device to treat blocked coronary artery

Washington: A group of cardiologists has successfully used a virtual reality (VR) device to guide the opening up (revascularization) of a chronically blocked right coronary artery. Their report is published in the Canadian Journal of Cardiology. more

Study shows superiority of one drug eluting sent over another in diabetics

New Delhi: A study conducted by researchers at Fortis Escorts Heart Institute, New Delhi has demonstrated the superiority of Everolimus eluting stents over Paclitaxel eluting stents in patients with diabetes mellitus and coronary artery disease. more

New heart attack test could identify two-thirds of patients at very low risk of heart attack in the emergency department

New heart attack test could identify two-thirds of patients at very low risk of heart attack in the emergency department

London: Using a high sensitivity blood test, researchers have identified the optimal level of a protein called troponin that could rule out a diagnosis of heart attack for two-thirds of people attending the emergency department, according to new research published in The Lancet. more

UV-light enabled catheter fixes holes in the heart without invasive surgery

UV-light enabled catheter fixes holes in the heart without invasive surgery

Washington: Researchers from Boston Children’s Hospital, the Wyss Institute for Biologically Inspired Engineering at Harvard University, Harvard John A Paulson School of Engineering and Applied Sciences (SEAS) and the Karp Lab at Brigham and Women’s Hospital have jointly designed a specialized catheter for fixing holes in the heart using a biodegradable adhesive and patch. more

Diagnostic imaging can rule out coronary artery disease in patients with atypical chest pain

Diagnostic imaging can rule out coronary artery disease in patients with atypical chest pain

New York: Non-invasive diagnostic imaging can rule out coronary artery disease (CAD) in about 50% of women with atypical chest pain who are at relatively low risk for CAD, while exposing them to only a modest dose of radiation. more
