Commonly used intra-aortic balloon pump may have broader potential for heart patients

Commonly used intra-aortic balloon pump may have broader potential for heart patients

The most frequently used mechanical circulatory assist device in the world may have untapped potential, physicians say. One of many uses for the intra-aortic balloon pump is helping ensure adequate oxygen and blood delivery to a heart struggling to resume beating in the aftermath of coronary bypass surgery, said Dr. Mary Arthur, cardiovascular anesthesiologist at the Medical College of Georgia and Georgia Regents Health System.

Analysis supports use of risk equations to guide statin therapy

Analysis supports use of risk equations to guide statin therapy

In an analysis of almost 11,000 patients, an assessment of equations that help guide whether a patient should begin taking a statin (cholesterol lowering medication) found that observed and predicted 5-year atherosclerotic cardiovascular disease risks were similar, suggesting that these equations are helpful for clinical decision making, according to a JAMA study released online to coincide with presentation at the 2014 American College of Cardiology Scientific Sessions.

In an analysis of almost 11,000 patients, an assessment of equations that help guide whether a patient should begin taking a statin (cholesterol lowering medication) found that observed and predicted 5-year atherosclerotic cardiovascular disease risks were similar, suggesting that these equations are helpful for clinical decision making, according to a JAMA study released online to coincide with presentation at the 2014 American College of Cardiology Scientific Sessions. The American College of Cardiology (ACC) and the American Heart Association (AHA) recently published the 2013 Guideline on the Assessment of Cardiovascular Risk. As part of this guideline, a group of experts developed the Pooled Cohort risk equations, which were designed to estimate 10-year risk for nonfatal myocardial infarction (MI; heart attack), coronary heart disease (CHD) death, and nonfatal or fatal stroke, according to background information in the article Continue reading

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.

Are statins good for your love life?

Are statins good for your love life?

Statins are associated with a significant improvement in erectile function, a fact researchers hope will encourage men who need statins to reduce their risk of heart attack to take them, according to research to be presented at the American College of Cardiology’s 63rd Annual Scientific Session.
