Patient immune response could prevent heart failure

Patients’ own immune response has the potential to prevent the development and progression of heart failure, according to research presented at Frontiers in CardioVascular Biology (FCVB) 2018, a European Society of Cardiology congress. The study found antibodies in the plasma and heart muscle of end-stage heart failure patients. “The role of the immune response in the development of heart…

Matrix-forming proteins

Experimental targeted therapy might prevent heart failure

Scientists used an experimental targeted molecular therapy to block a matrix-forming protein in heart cells damaged by heart attack, reducing levels of scarred muscle tissue and saving mouse models from heart failure. Researchers at the Cincinnati Children’s Heart Institute report in the journal Circulation testing a manufactured peptide called pUR4 to block the fibronectin protein in human…

Leveling intensity

Even two minutes of activity can reduce death risk

Walking 10,000 steps a day or a doing a quick workout from a phone app - all of those tactics could work to reduce risk of disease and death, according to new research. The study found that even brief trips up and down stairs would count toward accumulated exercise minutes and reducing health risks so long as the intensity reaches a moderate or vigorous level. The most dramatic improvements in…

Defibrillator use

Italian law must change to improve survival from cardiac arrest

An Italian law requiring citizens to hold a certificate to use a defibrillator must change to improve survival from cardiac arrest, researchers argued today at Acute Cardiovascular Care 2018, a European Society of Cardiology congress. “Automated external defibrillator (AED) use before the arrival of the emergency medical services (EMS) plays a key role in improving victim survival from…

Standard medical tests miss nearly two-thirds of heart attack diagnoses

Standard medical tests miss nearly two-thirds of heart attack diagnoses, reveals research presented at CMR 2018. “Unrecognised MI has a poor short-term prognosis but until now the long-term outlook was unknown,” said lead author Dr Tushar Acharya, a cardiologist at the National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, US. “This study investigated long-term…

Ventricular tachycardia

Deadly heart rhythm halted by noninvasive radiation therapy

Radiation therapy often is used to treat cancer patients. Now, doctors at Washington University School of Medicine in St. Louis have shown that radiation therapy — aimed directly at the heart — can be used to treat patients with a life-threatening heart rhythm. They treated five patients who had irregular heart rhythms, called ventricular tachycardia, at the School of Medicine. The patients…

Coordinated emergency care improves heart attack survival

Coordinating the response to heart attacks among emergency responders and hospitals reduces the time to treatment and saves lives - even on a large, regional scale, according to a study led by the Duke Clinical Research Institute with support from the American Heart Association. In the largest demonstration of the coordinated approach - 132 hospitals and 946 EMS agencies in 12 U.S. regions -…

Cardiology, quick!

New blood test speeds up heart attack diagnosis

A new blood test to detect heart attacks has been developed by a team of researchers at King’s College, London, which could speed up diagnosis, according to results from pan-European trials. The test is quicker than the standard test, which combines an ECG with a blood test to measure the levels of troponin. Under current guidelines, suspected heart attack cases are tested for high blood…

Saving hearts after a heart attack

University of Alabama at Birmingham biomedical engineers report a significant advance in efforts to repair a damaged heart after a heart attack, using grafted heart-muscle cells to create a repair patch. The key was overexpressing a gene that activates the cell-cycle of the grafted muscle cells, so they grow and divide more than control grafted cells.

Cardiac injury

Could this be the way to mend a broken heart?

Early research results suggest scientists might be on to a way to preserve heart function after heart attacks or for people with inherited heart defects called congenital cardiomyopathies. Researchers at the Cincinnati Children’s Heart Institute report in Nature Communications that after simulating heart injury in laboratory mouse models, they stopped or slowed cardiac fibrosis, organ…

Fast triage of chest pain patients

ADVIA Centaur High-Sensitivity Troponin I Assay

The ADVIA Centaur® High-Sensitivity Troponin I (TNIH) assay* is the latest addition to Siemens Healthineers’ comprehensive cardiac menu to assist clinicians with the diagnosis and treatment of chest pain patients. Designed to aid in diagnosing acute myocardial infarctions (AMI) through the quantitative measurement of cardiac troponin I in serum or plasma, high-sensitivity troponin plays a…

Potential Breakthrough in Determining Who’s at Risk

Researchers are revisiting their views on the relative dangers soft and hard atherosclerotic plaque deposits pose to heart health. Findings of a new study by researchers at the Intermountain Medical Center Heart Institute may be a “game-changer” for determining who’s at risk of a heart attack, they say.

Advancing AF and renal dysfunction care

An innovative cardiac monitoring system that delivers continuous resynchronisation to patients, has shown a 35% risk reduction of hospitalisation for heart failure (HF) patients. The finding comes from the RESPOND-CRT (cardiac resynchronisation therapy) clinical trial, which was designed to investigate the clinical efficacy and safety of device-based optimisation using the SonR cardiac…

Testosterone clue to male heart deaths

As men appear to have higher risk of cardiovascular disease (CVD) than women of a similar age – with vascular calcification a strong predictor of mortality and morbidity from CVD – a team from the University of Edinburgh hopes that exploration of a link between gender and calcification could help unlock the pathway to new therapies. The researchers have been looking at whether sex hormones…

Plaque

Research suggests new contributor to heart disease

Medical professionals have long known that the buildup of plaque in arteries can cause them to narrow and harden, potentially leading to a whole host of health problems — including heart attack, heart disease and stroke. While high blood pressure and artery stiffness are often associated with plaque buildup, new research from engineers at Washington University in St. Louis shows they are not…

POC test detects myocardial infarction

Philips Minicare delivers rule-in/rule-out readings for heart attacks in 10 minutes. It takes a lot of hard work to make things easy. Biomedical experts at Royal Philips have spent more than 10 years developing a simple test for the emergency department that, in less than 10 minutes, may indicate whether a patient suffering chest pains is having a heart attack.
