Physical Activity Improves Heart Rate Variability In The Elderly

Larry Husten, PHD

A new study in Circulation offers fresh evidence that physical activity is beneficial to the heart in people aged 65 and older. Benefits were observed both in elderly people who reported the highest amount of overall physical activity and in those who increased their physical activity over time. U.S. researchers evaluated heart rate variability (HRV) using […]

Controversy Erupts Over Accuracy of Cardiovascular Risk Calculator for Guidelines

Larry Husten, PHD

In the face of a highly critical story in the New York Times by Gina Kolata about the new cardiovascular guidelines, authors of the guidelines and leaders of the American Heart Association (AHA) and the American College of Cardiology (ACC) defended the value and integrity of the guidelines. The Times story claims that the cardiovascular risk calculator used to assess individual risk in the new guidelines is deeply […]

Hip and Knee Replacements Associated with Lower CV Risk

Total joint arthroplasty was associated with reduced cardiovascular risk among patients with knee or hip osteoarthritis in a BMJ study. Researchers in Canada matched roughly 150 people aged 55 or older with moderate-to-severe knee or hip osteoarthritis who underwent total joint replacement to people with osteoarthritis who did not have surgery. People who underwent arthroplasty were less […]

People Who Live Near Airports at Increased Risk for Cardiovascular Disease

Larry Husten, PHD

Most previous research on the health effects of noise has focused on road noise. Now two new observational studies published in BMJ extend the research to noise from airports and provide fresh evidence that people who live near airports are at increased risk for cardiovascular disease. In the first paper, Anna Hansell and colleagues in the U.K. analyzed data from 3.6 […]

Macrolide Antibiotic Linked to Increased CV Risk in Patients with Lung Conditions

Nicholas Downing, MD

Use of the macrolide clarithromycin in patients admitted with exacerbations of chronic obstructive pulmonary disease or community-acquired pneumonia is associated with increased risk for cardiovascular events, a BMJ study finds. Researchers examined outcomes among nearly 3000 patients admitted to U.K. hospitals with either condition. During 1 year of follow-up, there were roughly 450 new admissions for […]
