How to Reverse Acute Ischemic StrokeAugust 2018
By William Faloon
In 2018, the American Heart Association and the American Stroke Association released new guidelines that radically change the landscape of acute ischemic stroke treatment.1
The magnitude of this advance cannot be overstated.
Instead of suffering lifelong disability, one out of three stroke patients can now fully recover.2
We at Life Extension® applaud recognition of this game-changing technology. It will spare millions from permanent paralysis, nursing homes, and death.
Our issue with these “new” stroke-treatment guidelines is they could have been adopted sooner.
The technique announced this year involves threading a catheter into a blocked cerebral artery and mechanically removing the clot that is occluding blood flow. The medical term for this is:
If this sounds familiar, it’s because we described it three years ago in this magazine and passionately argued for widespread use.3
The New England Journal of Medicine concurred with our position and criticized the lag in implementing this stroke-reversal treatment.4,5
My overriding concern is other effective therapies that people remain largely unaware of.
This means only scant fractions of the public gain access to lifesaving techniques.
The mission of Life Extension® is to keep our readers informed about novel approaches to disease prevention and treatment.
This article describes simple ways to reduce your risk of stroke and what to do if stroke symptoms manifest.
More than 2,000 Americans suffer a stroke on an average day.6
Some will recover with minor outward effects, while others endure paralysis and prolonged nursing-home confinement.
Most strokes happen when a blood clot blocks an artery that feeds a portion of the brain.7 As neurons die, the result can be paralysis, blindness, and cognitive dysfunction.8,9
Stroke is a leading cause of long-term disability in the United States. It’s the fifth leading cause of death.6
The tragedy is that many acute ischemic strokes can be reversed if thrombectomy intervention is delivered in a timely manner.10 This treatment should have become routine emergency room practice several years ago.
Evolving at a Snail’s Pace
The box on this page provides a succinct timeline of medical advances that enable doctors to dissolve or mechanically remove blood clots that occlude arteries in the heart and brain.
One of these involves a drug called tPA (tissue plasminogen activator) that can dissolve clots blocking arteries in the heart and brain.
The FDA approved tPA in 1987, but it could have been made available earlier.
Former talk-show host Larry King was saved from sudden death by tPA because he was fortunate to be taken to a hospital that was a clinical study center. After recovery, King asked why everyone was not given access to the tPA drug that saved his life.
When King learned the FDA was delaying approval of tPA, he launched a public relations campaign that, along with Life Extension, was harshly critical of the FDA holding back approval of this clot-dissolving drug.
Within six months, the FDA approved tPA to treat acute coronary artery occlusion.
It took another nine years before the FDA approved tPA to reverse cerebral artery blockage (ischemic stroke).
Delay Extends Beyond FDA
I’ve authored numerous articles critical of FDA impediments that preclude timely introduction of lifesaving therapies.
The delay in bringing forth the clot-busting drug tPA and mechanical clot-retrieving thrombectomy, however, lies more with an apathetic (and overworked) medical establishment that is too slow in adopting better treatment methods.
Long after the FDA’s belated approval of tPA in 1996 to reverse ischemic stroke, less than 7% of potential stroke victims were administered the drug (as of year 2010).12
The lag time in implementing widespread use of mechanical clot retrieval (thrombectomy) is also troubling.
Despite inconsistent findings from initial thrombectomy trials using primitive techniques, by 2015 the evidence clearly demonstrated significant benefit over risk.11 Yet three years went by before conventional medicine formally adopted the procedure.
Every year, about 200,000 Americans are confined to nursing homes or rehabilitation facilities due to stroke-inflicted brain damage.13
A significant percentage of these miseries would have been avoided if tPA and thrombectomy had been instituted sooner by ER departments…long after the FDA’s belated approvals.
Huge Advance Announced in 2017
In findings presented at the European Stroke Organization Conference on May 16, 2017, researchers showed that thrombectomy (mechanical retrieval of cerebral blood clots) was effective up to 24 hours after stroke symptom onset.14-16
A scientist from the University of Pittsburgh Medical Center Stroke Center stated:
“This is the largest treatment effect we have seen (in stroke).”17
While this was hot news for the media, it was not to us at Life Extension.
That’s because we had made phone calls to Comprehensive Stroke Centers several years ago and were informed of successful acute stroke reversals long after conventional guidelines of six hours.
A list of comprehensive stroke centers and the names of hospitals offering these acute stroke reversal therapies may be found at: www.LifeExtension.com/stroke
A reason some stroke victims benefit from thrombectomy as long as 24 hours after acute arterial occlusion is a phenomenon known as “collateral circulation.” This enables a portion of the brain to be fed by multiple smaller blood vessels, even though a major cerebral artery is acutely blocked.
Research long ago demonstrated that brain cells survive far longer than what conventional medicine realizes, especially in the presence of lowered body temperature (hypothermia). But even warm ischemia research shows impressive findings.
Victims of Delay
The new 2018 guidelines from the American Heart Association/American Stroke Association are welcome news to humanity and medical science.1
What they starkly reveal, however, is that large numbers of people have been permanently paralyzed (or have died) who could have been saved utilizing existing technologies (thrombectomy and/or tPA).
In other words, many stroke victims who were rushed to hospital emergency rooms were given up on too soon by medical personnel, who failed to realize the lifesaving advantages of aggressive use of tPA and/or thrombectomy.
For people in otherwise decent health, failure of hurried doctors to more aggressively attempt to remove (or dissolve) cerebral blood clots could result in years of paralysis in institutional confinement (or cemeteries).
A founding tenet of Life Extension is that humans in need are too often denied access to experimental and proven therapies. Our most powerful weapon to mitigate this crisis is to convey real-world solutions in the pages of this magazine.
Improved Standards for Acute Stroke Reversal
About 300 hospitals around the country now use new automated brain imaging software (called RAPID) to identify patients who may be candidates for thrombectomy after their six-hour window has expired.2
The new RAPID software analyzes CT or MRI scan results to look at blood-flow levels in the brain. This allows doctors to determine if thrombectomy can help those who have blood-flow occlusion caused by acute clot.
The new guidelines recommend an increased treatment window for clot removal from six hours to 24 hours based on brain imaging in select patients. This enables expanded eligibility for clot-busting drugs and mechanical procedures like thrombectomy.
Dr. Walter Koroshetz, director of the National Institute of Neurological Disorders and Stroke, commented on the new guidelines for expanding the window for thrombectomy use:
“I really cannot overstate the size of this effect. The study shows that one out of three patients are saved from the devastation of a stroke, and can walk out of the hospital, completely recovered… The results of the trial were astounding and will have an immediate impact in the clinic and will help us save many lives.”2
What Took So Long?
We at Life Extension cannot express enough gratitude to the scientific community for these life-sparing medical advances.
Our ongoing concern, however, is the sluggish pace at which innovation translates into clinical practice.
From what the medical establishment now acknowledges, over two million American lives could have been spared the disabling miseries of stroke-induced paralysis (and death) if tPA and enhanced-thrombectomy interventions had been advanced sooner.
These kinds of delays impacting the health and longevity of Americans today are not unique to stroke. I am currently investigating numerous interventions to delay if not reverse biological aging. Yet obstacles to moving discoveries into the clinical setting remain daunting.
The excuses I hear for foot dragging are eerily reminiscent of what caused so few ER physicians (less than 7% by year 2010) to utilize tPA, and even fewer to attempt thrombectomy. Recall the FDA approved tPA for acute stroke in 1996.
We acknowledge side-effect concerns with tPA such as excessive bleeding. But when a stroke patient lies in an emergency room, and the treating physician does nothing but watch the patient slowly undergo permanent paralysis, we think the risk-to-benefit ratio should be revised.
Stroke Prevention Far More Effective
While treatment advances that have occurred since 1987 in reversing occlusive arterial disease are impressive, it is far more efficient to protect against it.
Ischemic strokes are caused by blood clots that form in an artery feeding the brain (thrombotic stroke) OR when a blood clot forms elsewhere in the body and travels to a cerebral artery (embolic stroke).26
Narrowing of arteries feeding the brain can create acute or chronic blockages of blood flow.
Atrial fibrillation is a common cause of embolic strokes, which is why powerful anticoagulant drugs are prescribed to people with certain heartbeat irregularities. These drugs have side effects, but the data show the antithrombotic benefits outweigh the increased bleeding risks.
When one realizes that formation of abnormal blood clots (thrombosis) in arteries and veins represents a major health threat, one can understand the importance of proactively maintaining healthy circulatory function.
On page 52, you can read a reprint from a front-page article on stroke reversal published this year in the Wall Street Journal. The first article in this month’s issue describes a new spearmint tea that has been shown to provide an immediate boost in mental focus, attention, and concentration.27
