Astronauts’ hearts become more spherical in space

Astronauts’ hearts become more spherical in space

New findings from a study of 12 astronauts show the heart becomes more spherical when exposed to long periods of microgravity in space, a change that could lead to cardiac problems, according to research to be presented at the American College of Cardiology’s 63rd Annual Scientific Session. With implications for an eventual manned mission to Mars, the findings represent an important step toward understanding how a spaceflight of 18 months or more could affect astronauts’ heart health. “The heart doesn’t work as hard in space, which can cause a loss of muscle mass,” said James Thomas, M.D., Moore Chair of Cardiovascular Imaging and Lead Scientist for Ultrasound at NASA, and senior author of the study.

Improving quality, safety for PCIs performed without on-site backup

Improving quality, safety for PCIs performed without on-site backup

The increasing number of percutaneous coronary interventions (PCIs) being performed at low-volume centers without on-site cardiac surgery backup has driven the need for new safety and quality protocols, according to an expert consensus document released today and written by a committee representing the Society for Cardiovascular Angiography and Interventions (SCAI), the American College of Cardiology Foundation (ACCF) and the American Heart Association (AHA).

Blood poisoning increases the risk of blood clots, new research shows

Every year, almost 10,000 Danes are admitted to hospital with blood poisoning, while more than 3,000 patients become infected while they are hospitalized. New research shows that Danes suffering from blood poisoning risk an extra challenge in the form of an increased risk of suffering a blood clot: “We have followed more than 4,000 people who have been admitted with blood poisoning.

Blood poisoning increases the risk of blood clots, new research shows

Every year, almost 10,000 Danes are admitted to hospital with blood poisoning, while more than 3,000 patients become infected while they are hospitalized. New research shows that Danes suffering from blood poisoning risk an extra challenge in the form of an increased risk of suffering a blood clot: “We have followed more than 4,000 people who have been admitted with blood poisoning. The study shows that the risk of suffering a blood clot in either the brain or the heart is twice as high for patients with blood poisoning in relation to other patients who are also admitted with acute illnesses,” says Michael Dalager-Pedersen , PhD student at Aarhus University and Registrar at Aalborg University Hospital Continue reading

Antidepressant heart risk confirmed

Antidepressant heart risk confirmed

30 January 2013 Last updated at 02:51 ET Some but not all antidepressant drugs known as SSRIs pose a very small but serious heart risk, say researchers. Citalopram and escitalopram, which fall into this drug group, can trigger a heart rhythm disturbance, a new study in the British Medical Journal shows. UK and US regulators have already warned doctors to be extra careful about which patients they prescribe these medicines to. Continue reading
