Last week, ACVP blog's analysis of heart disease as a medical mystery left our readers with a few big questions.

Despite all the research and measurement into heart disease on a national and global scale - are we any closer to satisfying answers about how best to continue to decrease heart disease mortality rates?

The history of the heart disease decline - and all the research that came out of it - still might leave us (surprisingly) lost for hard answers.

Attribution of causes, historically, a murky process

In 2013, medical historians David S. Jones, MD, PhD of Harvard Medical School and Jeremy A. Greene, MD, PhD of Johns Hopkins School of Medicine published a history of the decline of heart disease mortality in the American Journal of Public Health.

Following their peak in the early 1960s, heart disease mortality rates shockingly declined 20 percent between 1968 and 1978---a decline so large and without simple explanation that a conference was called to determine whether the decline was "real." (It was.)

"Quite simply, the problem was that too many things had changed," write Jones and Greene.

"Something strange is going on in medicine," writes the New York Times's Gina Kolata - major diseases are are on the wane, and in some cases, it's a mystery as to why.

A decline in mortality from colon cancer is "especially perplexing," writes Kolata - a decline by nearly 50 percent since its peak in the 1980s has left researchers searching for an answer, since more screening couldn't possibly indicate such a large decline.

Heart disease mortality still declining, but slowing

Despite still being the number one cause of death in the world and the United States, death rates from cardiovascular disease and stroke have been steadily and significantly declining since the 1970s.

From 2000 to 2010, age-adjusted mortality decreased 30 percent for heart disease and 36 percent for stoke. And with cancer mortality declining by only 13 percent over that time period, it looked as if heart disease might lose its status as leading cause of death in the United States for the first time since 1910.

Not so fast.
