Heart-healthy and Stroke-free Living with Michael Mattice, MD

For decades, cholesterol was demonized as the No. 1 threat to heart, brain and arterial health. Then a growing body of evidence began to zero in on another villain. “The four horsemen of the medical apocalypse — coronary artery disease, diabetes, cancer, and Alzheimer’s — may be riding the same steed: inflammation,” a Harvard paper theorized in 2006. Since then, recent landmark studies have shown that chronic systemic inflammation, which we call “fire,” is both a cause of heart attacks and strokes and an important treatment target to help prevent them.

In 2017, the CANTOS trial generated worldwide headlines by reporting that therapies to lower inflammation — without lowering cholesterol — reduced risk for cardiovascular events and cancer by up to 50 percent. An even newer landmark study by 24 of the world’s top experts on Alzheimer’s disease (AD) and other forms of dementia, published in Lancet, was the first to report that these memory-robbing brain disorders may be preventable with strategies that include reducing brain inflammation. Here is a look at the latest discoveries and how to use them to keep your brain healthy and your memory sharp.

What is chronic inflammation and why is it so dangerous? Inflammation is a normally protective response to injury and infection. If you stepped on a rusty nail, cells in the affected area would mobilize immune system troops to battle the invading bacteria. Called “the inflammatory cascade,” this call to arms involves more than 20 proteins that blast the invaders with toxins to kill them. Chronic inflammation harms rather than heals because the immune system attack never stops. The result is like being shot by “friendly fire” in an endless war raging within the body. In 2012, two landmark studies published in Lancet were the first to show that chronic inflammation actually causes cardiovascular disease (CVD), the leading killer of Americans. This fiery process has been linked to so many other deadly or debilitating conditions that some scientists call it “the root of all diseases.” Heart attacks and strokes are triggered when a diseased artery becomes so inflamed that it can no longer contain the plaque smoldering inside. Like a volcano spewing molten lava, inflammation causes a breech in the artery wall, leading to the formation of a
