How 30 Years of Heart Surgeries Taught My Dad How to Live
[Editor's Note: This piece is the winner of our 2019 essay contest, which prompted readers to reflect on the question: "How has an advance in science or medicine changed your life?"]
My father did not expect to live past the age of 50. Neither of his parents had done so. And he also knew how he would die: by heart attack, just as his father did.
In July of 1976, he had his first heart attack, days before his 40th birthday.
My dad lived the first 40 years of his life with this knowledge buried in his bones. He started smoking at the age of 12, and was drinking before he was old enough to enlist in the Navy. He had a sarcastic, often cruel, sense of humor that could drive my mother, my sister and me into tears. He was not an easy man to live with, but that was okay by him - he didn't expect to live long.
In July of 1976, he had his first heart attack, days before his 40th birthday. I was 13, and my sister was 11. He needed quadruple bypass surgery. Our small town hospital was not equipped to do this type of surgery; he would have to be transported 40 miles away to a heart center. I understood this journey to mean that my father was seriously ill, and might die in the hospital, away from anyone he knew. And my father knew a lot of people - he was a popular high school English teacher, in a town with only three high schools. He knew generations of students and their parents. Our high school football team did a blood drive in his honor.
During a trip to Disney World in 1974, Dad was suffering from angina the entire time but refused to tell me (left) and my sister, Kris.
Quadruple bypass surgery in 1976 meant that my father's breastbone was cut open by a sternal saw. His ribcage was spread wide. After the bypass surgery, his bones would be pulled back together, and tied in place with wire. The wire would later be pulled out of his body when the bones knitted back together. It would take months before he was fully healed.
Dad was in the hospital for the rest of the summer and into the start of the new school year. Going to visit him was farther than I could ride my bicycle; it meant planning a trip in the car and going onto the interstate. The first time I was allowed to visit him in the ICU, he was lying in bed, and then pushed himself to sit up. The heart monitor he was attached to spiked up and down, and I fainted. I didn't know that heartbeats change when you move; television medical dramas never showed that - I honestly thought that I had driven my father into another heart attack.
Only a few short years after that, my father returned to the big hospital to have his heart checked with a new advance in heart treatment: a CT scan. This would allow doctors to check for clogged arteries and treat them before a fatal heart attack. The procedure identified a dangerous blockage, and my father was admitted immediately. This time, however, there was no need to break bones to get to the problem; my father was home within a month.
During the late 1970's, my father changed none of his habits. He was still smoking, and he continued to drink. But now, he was also taking pills - pills to manage the pain. He would pop a nitroglycerin tablet under his tongue whenever he was experiencing angina (I have a vivid memory of him doing this during my driving lessons), but he never mentioned that he was in pain. Instead, he would snap at one of us, or joke that we were killing him.
I think he finally determined that, if he was going to have these extra decades of life, he wanted to make them count.
Being the kind of guy he was, my father never wanted to talk about his health. Any admission of pain implied that he couldn't handle pain. He would try to "muscle through" his angina, as if his willpower would be stronger than his heart muscle. His efforts would inevitably fail, leaving him angry and ready to lash out at anyone or anything. He would blame one of us as a reason he "had" to take valium or pop a nitro tablet. Dinners often ended in shouts and tears, and my father stalking to the television room with a bottle of red wine.
In the 1980's while I was in college, my father had another heart attack. But now, less than 10 years after his first, medicine had changed: our hometown hospital had the technology to run dye through my father's blood stream, identify the blockages, and do preventative care that involved statins and blood thinners. In one case, the doctors would take blood vessels from my father's legs, and suture them to replace damaged arteries around his heart. New advances in cholesterol medication and treatments for angina could extend my father's life by many years.
My father decided it was time to quit smoking. It was the first significant health step I had ever seen him take. Until then, he treated his heart issues as if they were inevitable, and there was nothing that he could do to change what was happening to him. Quitting smoking was the first sign that my father was beginning to move out of his fatalistic mindset - and the accompanying fatal behaviors that all pointed to an early death.
In 1986, my father turned 50. He had now lived longer than either of his parents. The habits he had learned from them could be changed. He had stopped smoking - what else could he do?
It was a painful decade for all of us. My parents divorced. My sister quit college. I moved to the other side of the country and stopped speaking to my father for almost 10 years. My father remarried, and divorced a second time. I stopped counting the number of times he was in and out of the hospital with heart-related issues.
In the early 1990's, my father reached out to me. I think he finally determined that, if he was going to have these extra decades of life, he wanted to make them count. He traveled across the country to spend a week with me, to meet my friends, and to rebuild his relationship with me. He did the same with my sister. He stopped drinking. He was more forthcoming about his health, and admitted that he was taking an antidepressant. His humor became less cruel and sadistic. He took an active interest in the world. He became part of my life again.
The 1990's was also the decade of angioplasty. My father explained it to me like this: during his next surgery, the doctors would place balloons in his arteries, and inflate them. The balloons would then be removed (or dissolve), leaving the artery open again for blood. He had several of these surgeries over the next decade.
When my father was in his 60's, he danced at with me at my wedding. It was now 10 years past the time he had expected to live, and his life was transformed. He was living with a woman I had known since I was a child, and my wife and I would make regular visits to their home. My father retired from teaching, became an avid gardener, and always had a home project underway. He was a happy man.

Then, in the mid 2000's, my father faced another serious surgery. Years of arterial surgery, angioplasty, and damaged heart muscle were taking their toll. He opted to undergo a life-saving surgery at Cleveland Clinic. By this time, I was living in New York and my sister was living in Arizona. We both traveled to the Midwest to be with him. Dad was unconscious most of the time. We took turns holding his hand in the ICU, encouraging him to regain his will to live, and making outrageous threats if he didn't listen to us.
The nursing staff were wonderful. I remember telling them that my father had never expected to live this long. One of the nurses pointed out that most of the patients in their ward were in their 70's and 80's, and a few were in their 90's. She reminded me that just a decade earlier, most hospitals were unwilling to do the kind of surgery my father had received on patients his age. In the first decade of the 21st century, however, things were different: 90-year-olds could now undergo heart surgery and live another decade. My father was on the "young" side of their patients.
The Cleveland Clinic visit would be the last major heart surgery my father would have. Not that he didn't return to his local hospital a few times after that: he broke his neck -- not once, but twice! -- slipping on ice. And in the 2010's, he began to show signs of dementia, and needed more home care. His partner, who had her own health issues, was not able to provide the level of care my father needed. My sister invited him to move in with her, and in 2015, I traveled with him to Arizona to get him settled in.
After a few months, he accepted home hospice. We turned off his pacemaker when the hospice nurse explained to us that the job of a pacemaker is to literally jolt a patient's heart back into beating. The jolts were happening more and more frequently, causing my Dad additional, unwanted pain.
My father in 2015, a few months before his death.
My father died in February 2016. His body carried the scars and implants of 30 years of cardiac surgeries, from the ugly breastbone scar from the 1970's to scars on his arms and legs from borrowed blood vessels, to the tiny red circles of robotic incisions from the 21st century. The arteries and veins feeding his heart were a patchwork of transplanted leg veins and fragile arterial walls pressed thinner by balloons.
And my father died with no regrets or unfinished business. He died in my sister's home, with his long-time partner by his side. Medical advancements had given him the opportunity to live 30 years longer than he expected. But he was the one who decided how to live those extra years. He was the one who made the years matter.
Kelly, a case manager for an insurance company, spent years battling both migraines and Crohn's, a disease in which the immune system attacks the intestines.
For many people, like Kelly, a stronger electric boost to the vagus nerve could be life-changing.
After she had her large intestine removed, her body couldn't absorb migraine medication. Last year, about twice a month, she endured migraines so bad she couldn't function. "It would go up to a ten, and I would rock, wait it out," she said. The pain might last for three days.
Then her neurologist showed her a new device, gammaCore, that tames migraines by stimulating a nerve—not medication. "I don't have to put a chemical in my body," she said. "I was thrilled."
At first, Kelly used the device at the onset of a migraine, applying electricity to her pulse at the front of her neck for six minutes. The pain peaked at about half the usual intensity--low enough, she said, that she could go to work. Four months ago, she began using the device for two minutes each night as prevention, and she hasn't had a serious migraine since.
The Department of Defense and Veterans Administration now offer gammaCore to patients, but it hasn't yet been approved by Medicare, Medicaid, or most insurers. A month of therapy costs $600 before insurance or a generous financial assistance program kicks in.

If the poet Walt Whitman wrote "I Sing The Body Electric" today, he might get specific and point to the vagus nerve, a bundle of fibers that run from the brainstem down the neck to the heart and gut. Singing stimulates it—and for many people, like Kelly, a stronger electric boost to the nerve could be life-changing.
The mind-body connection isn't just an idea — the vagus nerve literally carries signals from the mind to the body and back. It may explain the link between childhood trauma and illnesses such as chronic pain and headaches in adults. "How is it possible that a psychological event causes pain years later?" asked Peter Staats, co-founder of electroCore, which has won approval for its new device from the Food and Drug Administration (FDA) for both migraine and cluster headaches. "There has to be a mind-body interface, and that is the vagus nerve," he said.
Scientists knew that this nerve controlled your heart rate and blood pressure, but in the past decade it has been linked to both pain and the immune system.
"Everything is gated through the vagus -- problems with the gut, the heart, and the lungs," said Chris Wilson, a researcher at Loma Linda University, in California. Wilson is studying how vagus nerve stimulation (VNS) could help pre-term babies who develop lung infections. "Nearly every one of our chronic diseases, including cancer, Alzheimer's, Parkinson's, chronic arthritis and rheumatoid arthritis, and depression and chronic pain…could benefit from an appropriate stimulator," he said.
It's unfortunate that Kelly got her device only after her large intestine was gone. SetPoint Medical, a privately held California company founded to develop electronic treatments for chronic autoimmune diseases, has announced early positive results with VNS for both Crohn's and rheumatoid arthritis.
As SetPoint's chief medical officer, David Chernoff, put it, "We're hacking into the nervous system to activate a system that is already there," an approach that, he said, could work "on many diseases that are pain- and inflammation-based." Inflammation plays a role in much modern illness, including depression and obesity. The FDA already has approved VNS for both, using surgically implanted devices similar to pacemakers. (GammaCore is external.)
The history of VNS implants goes back to 1997, when the FDA approved one for treating epilepsy and researchers noticed that it rapidly lifted depression in epileptic patients. By 2005, the agency had approved an implant for treatment-resistant depression. (Insurance companies declined to reimburse the approach and it didn't take off, but that might change: in February, the Center for Medicare and Medicaid Services asked for more data to evaluate coverage.) In 2015, the FDA approved an implant in the abdomen to regulate appetite signals and help obese people lose weight.
The link to inflammation had emerged a decade earlier, when researchers at the Feinstein Institute for Medical Research, in Manhasset, New York, demonstrated that stimulating the nerve with electricity in rats suppressed the production of cytokines, a signaling protein important in the immune system. The researchers developed a concept of a hard-wired pathway, through the vagus nerve, between the immune and nervous system. That pathway, they argued, regulates inflammation. While other researchers argue that VNS is helpful by other routes, there is clear evidence that, one way or another, it does affect immunity.
At the same time, investors are seeking alternatives to drugs.
The Feinstein rat research concluded that it took only a minute a day of stimulation and tiny amounts of energy to activate an anti-inflammatory reflex. This means you can use devices "the size of a coffee bean," said Chernoff, much less clunky than current pacemakers—and advances in electronic technology are making them possible.
At the same time, investors are seeking alternatives to drugs. "There's been a push back on drug pricing," noted Lisa Rhoads, a managing director at Easton Capital Investment Group, in New York, which supported electroCore, "and so many unintended consequences."
In 2016, the U.S. National Institutes of Health began pumping money into relevant research, in a program called "Stimulating Peripheral Activity to Relieve Conditions," which focuses on "understanding peripheral nerves — nerves that connect the brain and spinal cord to the rest of the body — and how their electrical signals control internal organ function."
GlaxoSmithKline formed Galvani Bioelectronics with Google to study miniature implants. It had already invested in Action Potential Venture Capital, in Cambridge, Massachusetts, which holds SetPoint and seven other companies "that are all targeting a nerve to treat a chronic disease," noted partner Imran Eba. "I see a future in which bioelectronics medicine is competing directly with drugs," he said.
Treating the body with electricity could bring more ease and lower costs. Many people with serious auto-immune disease, for example, have to inject themselves with drugs that cost $60,000 a year. SetPoint's implant would cost less and only need charging once a week, using a charger worn around the neck, Chernoff said. The company receives notices remotely and can monitor compliance.
Implants also allow the treatment to target a nerve precisely, which could be important with Parkinson's, chronic pain, and depression, observed James Cavuoto, editor and publisher of Neurotech Reports. They may also allow for more fine-turning. "In general, the industry is looking for signals, biomarkers that indicate when is the right time to turn on and turn off the stimulation. It could dramatically increase the effectiveness of the therapy and conserve battery life," he said.
Eventually, external devices could receive data from biomarkers as well. "It could be something you wear on your wrist," Cavuoto noted. Bluetooth-enabled devices could communicate with phones or laptops for data capture. External devices don't require surgery and put the patient in charge. "In the future you'll see more customer specification: Give the patient a tablet or phone app that lets them track and modify their parameters, within a range. With digital devices we have an enormous capability to customize therapies and collect data and get feedback that can be fed back to the clinician," Cavuoto said.
Slow deep breathing, the traditional mind-body intervention, is "like watching Little League. What we're doing is Major League."
It's even possible to stimulate the vagus through the ear, where one branch of the bundle of fibers begins. In a fetus, the tissue that becomes the ear is also part of the vagus nerve, and that one bit remains. "It's the same point as the acupuncture point," explained Mark George, a psychiatrist and pioneer researcher in depression at Medical University of South Carolina in Charleston. "Acupuncture figured out years ago by trial and error what we're just learning about now."
Slow deep breathing, the traditional mind-body intervention, also affects the vagus nerve in positive ways, but gently. "That's like watching Little League," Staats, the co-founder of electroCore, said. "What we're doing is Major League."
In ten years, researcher Wilson suggested, you could be wearing "a little ear cuff" that monitors your basic autonomic tone, a heart-attack risk measure governed in part by the vagus nerve. If your tone looked iffy, the stimulator would intervene, he said, "and improve your mood, cognition, and health."
In the meantime, we can take some long slow breaths, read Whitman, and sing.
“Siri, Read My Mind”: A New Device Lets Users Think Commands
Sometime in the near future, we won't need to type on a smartphone or computer to silently communicate our thoughts to others.
"We're moving as fast as possible to get the technology right, to get the ethics right, to get everything right."
In fact, the devices themselves will quietly understand our intentions and express them to other people. We won't even need to move our mouths.
That "sometime in the near future" is now.
At the recent TED Conference, MIT student and TED Fellow Arnav Kapur was onstage with a colleague doing the first live public demo of his new technology. He was showing how you can communicate with a computer using signals from your brain. The usually cool, erudite audience seemed a little uncomfortable.
"If you look at the history of computing, we've always treated computers as external devices that compute and act on our behalf," Kapur said. "What I want to do is I want to weave computing, AI and Internet as part of us."
His colleague started up a device called AlterEgo. Thin like a sticker, AlterEgo picks up signals in the mouth cavity. It recognizes the intended speech and processes it through the built-in AI. The device then gives feedback to the user directly through bone conduction: It vibrates your inner ear drum and gives you a response meshing with your normal hearing.
Onstage, the assistant quietly thought of a question: "What is the weather in Vancouver?" Seconds later, AlterEgo told him in his ear. "It's 50 degrees and rainy here in Vancouver," the assistant announced.
AlterEgo essentially gives you a built-in Siri.
"We don't have a deadline [to go to market], but we're moving as fast as possible to get the technology right, to get the ethics right, to get everything right," Kapur told me after the talk. "We're developing it both as a general purpose computer interface and [in specific instances] like on the clinical side or even in people's homes."
Nearly-telepathic communication actually makes sense now. About ten years ago, the Apple iPhone replaced the ubiquitous cell phone keyboard with a blank touchscreen. A few years later, Google Glass put computer screens into a simple lens. More recently, Amazon Alexa and Microsoft Cortana have dropped the screen and gone straight for voice control. Now those voices are getting closer to our minds and may even become indistinguishable in the future.
"We knew the voice market was growing, like with getting map locations, and audio is the next frontier of user interfaces," says Dr. Rupal Patel, Founder and CEO of VocalID. The startup literally gives voices to the voiceless, particularly people unable to speak because of illness or other circumstances.
"We start with [our database of] human voices, then train our deep learning technology to learn the pattern of speech… We mix voices together from our voice bank, so it's not just Damon's voice, but three or five voices. They are different enough to blend it into a voice that does not exist today – kind of like a face morph."
The VocalID customer then has a voice as unique as he or she is, mixed together like a Sauvignon blend. It is a surrogate voice for those of us who cannot speak, just as much as AlterEgo is a surrogate companion for our brains.
"I'm very skeptical keyboards or voice-based communication will be replaced any time soon."
Voice equality will become increasingly important as Siri, Alexa and voice-based interfaces become the dominant communication method.
It may feel odd to view your voice as a privilege, but as the world becomes more voice-activated, there will be a wider gap between the speakers and the voiceless. Picture going shopping without access to the Internet or trying to eat healthily when your neighborhood is a food desert. And suffering from vocal difficulties is more common than you might think. In fact, according to government statistics, around 7.5 million people in the U.S. have trouble using their voices.
While voice communication appears to be here to stay, at least for now, a more radical shift to mind-controlled communication is not necessarily inevitable. Tech futurist Wagner James Au, for one, is dubious.
"I'm very skeptical keyboards or voice-based communication will be replaced any time soon. Generation Z has grown up with smartphones and games like Fortnite, so I don't see them quickly switching to a new form factor. It's still unclear if even head-mounted AR/VR displays will see mass adoption, and mind-reading devices are a far greater physical imposition on the user."
How adopters use the newest brain impulse-reading, voice-altering technology is a much more complicated discussion. This spring, a video showed U.S. House Speaker Nancy Pelosi stammering and slurring her words at a press conference. The problem is that it didn't really happen: the video was manufactured and heavily altered from the original source material.
So-called deepfake videos use computer algorithms to capture the visual and vocal cues of an individual, and then the creator can manipulate it to say whatever it wants. Deepfakes have already created false narratives in the political and media systems – and these are only videos. Newer tech is making the barrier between tech and our brains, if not our entire identity, even thinner.
"Last year," says Patel of VocalID, "we did penetration testing with our voices on banks that use voice control – and our generation 4 system is even tricky for you and me to identify the difference (between real and fake). As a forward-thinking company, we want to prevent risk early on by watermarking voices, creating a detector of false voices, and so on." She adds, "The line will become more blurred over time."
Onstage at TED, Kapur reassured the audience about who would be in the driver's seat. "This is why we designed the system to deliberately record from the peripheral nervous system, which is why the control in all situations resides with the user."
And, like many creators, he quickly shifted back to the possibilities. "What could the implications of something like this be? Imagine perfectly memorizing things, where you perfectly record information that you silently speak, and then hear them later when you want to, internally searching for information, crunching numbers at speeds computers do, silently texting other people."
"The potential," he concluded, "could be far-reaching."
