Heart Disease: Get's worse as you get older

This story from Sciencedaily.com makes little sense to me. A recent study notes that people are at a higher risk of heart disease as they age. I always thought that was the case even before the study. Here's a quote:

"The results of the present investigation confirm that acute HF (Heart Failure) represents a considerable burden to the health of the community, particularly in older individuals. Given the aging of the U.S. population, and declining national death rates due to cardiovascular disease placing these individuals at increased risk for HF during their latter years of life, increasing trends in the magnitude and morbidity of HF are likely to continue for the foreseeable future."

Isn't this well-know already? What's the point to this study? If you know let me know. Thanks.
