Prevalence of Cardiovascular Disease Likely to Increase Despite Gains in Treatment

It is the best of times and the worst of times in the battle against cardiovascular disease. On the one hand, mortality rates from cardiovascular disease in the U.S. have dropped by more than half in the last 30 years, likely due in large part to improvements in treatment for elevated blood pressure and cholesterol […]

People Who Live Near Airports at Increased Risk for Cardiovascular Disease

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 […]

Cuban History Offers Important Lessons For Global Health Today

A large new study from Cuba shows the impressive benefits that can be achieved with weight loss and increased exercise. Much more ominously, the same study shows the dangers associated with weight gain and less exercise. In the study, published in BMJ, researchers took advantage of a “natural” experiment that occurred in Cuba as a result of a major […]

International Cardiovascular Device Registries: The Next Big Thing

A new initiative involving a wide variety of stakeholders — the FDA, the American College of Cardiology, the Society of Thoracic Surgeons, industry, medical journals, and others — could lead to an enormous international cooperative effort to make device registries a standard part of the practice of cardiology.

Autopsy Studies Find Dramatic Drop in Early Atherosclerosis Over the Past 60 Years

Military service members who died during the past decade were far less likely to have atherosclerosis than service members who died in Korea or Vietnam, according to a new study published in JAMA.

Hypertension And Smoking Top List Of Global Risk Factors

State of the Heart: AHA Publishes Year-End Statistical Update

Although deaths from cardiovascular disease have been declining for many years, continued progress is threatened by disturbing trends in U.S. lifestyles. That’s the clear message from the American Heart Association’s year-end report, “Heart Disease and Stroke Statistical Update 2013,” published in Circulation. “Americans need to move a lot more, eat healthier and less, and manage risk […]

A Proposal To Improve The Value Of Observational Studies

I believe that observational studies can reveal important truths and have a critical place in the portfolio of clinical research. However, I sometimes wonder, when I see a study, just how it was conducted. Was the study question clearly defined before the analyses were begun…or did the study question emerge only after the investigator conducted […]

Big Drop in MI Incidence and Fatality in England

Since 2002, the incidence of acute MI in England has dropped by one-half and the case fatality rate by one-third, according to a new study published in BMJ. The overall decline in deaths from MI is about equally due to improvements in the prevention of MI and the treatment of MI. Kate Smolina and colleagues analyzed data from […]

The Good, the Bad, and the Ugly: AHA Releases Update of Heart and Stroke Statistics

Once again, statistics on the cardiovascular health of the United States portray a complicated picture of improvement and decline. On the one hand, deaths from cardiovascular disease continue to decline. On the other hand, ominous trends, many stemming from the increase in obesity, suggest that the good news may not last much longer. The full […]
