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.
He Almost Died from a Deadly Superbug. A Virus Saved Him.
An attacking rogue hippo, giant jumping spiders, even a coup in Timbuktu couldn't knock out Tom Patterson, but now he was losing the fight against a microscopic bacteria.
Death seemed inevitable, perhaps hours away, despite heroic efforts to keep him alive.
It was the deadly drug-resistant superbug Acinetobacter baumannii. The infection struck during a holiday trip with his wife to the pyramids in Egypt and had sent his body into toxic shock. His health was deteriorating so rapidly that his insurance company paid to medevac him first to Germany, then home to San Diego.
Weeks passed as he lay in a coma, shedding more than a hundred pounds. Several major organs were on the precipice of collapse, and death seemed inevitable, perhaps hours away despite heroic efforts by a major research university hospital to keep Tom alive.

Then doctors tried something boldly experimental -- injecting him with a cocktail of bacteriophages, tiny viruses that might infect and kill the bacteria ravaging his body.
It worked. Days later Tom's eyes fluttered open for a few brief seconds, signaling that the corner had been turned. Recovery would take more weeks in the hospital and about a year of rehabilitation before life began to resemble anything near normal.
In her new book The Perfect Predator, Tom's wife, Steffanie Strathdee, recounts the personal and scientific ordeal from twin perspectives as not only his spouse but also as a research epidemiologist who has traveled the world to track down diseases.
Part of the reason why Steff wrote the book is that both she and Tom suffered severe PTSD after his illness. She says they also felt it was "part of our mission, to ensure that phage therapy wasn't going to be forgotten for another hundred years."

From Prehistoric Arms Race to Medical Marvel
Bacteriophages, or phages for short, evolved as part of the natural ecosystem. They are viruses that infect bacteria, hijacking their host's cellular mechanisms to reproduce themselves, and in the process destroying the bacteria. The entire cycle plays out in about 20-60 minutes, explains Ben Chan, a phage research scientist at Yale University.
They were first used to treat bacterial infections a century ago. But the development of antibiotics soon eclipsed their use as medicine and a combination of scientific, economic, and political factors relegated them to a dusty corner of science. The emergence of multidrug-resistant bacteria has highlighted the limitations of antibiotics and prompted a search for new approaches, including a revived interest in phages.
Most phages are very picky, seeking out not just a specific type of bacteria, but often a specific strain within a family of bacteria. They also prefer to infect healthy replicating bacteria, not those that are at rest. That's what makes them so intriguing to tap as potential therapy.
Tom's case was one of the first times that phages were successfully infused into the bloodstream of a human.
Phages and bacteria evolved measures and countermeasures to each other in an "arms race" that began near the dawn of life on the planet. It is not that one consciously tries to thwart the other, says Chan, it's that countless variations of each exists in the world and when a phage gains the upper hand and kills off susceptible bacteria, it opens up a space in the ecosystem for similar bacteria that are not vulnerable to the phage to increase in numbers. Then a new phage variant comes along and the cycle repeats.
Robert "Chip" Schooley is head of infectious diseases at the University of California San Diego (UCSD) School of Medicine and a leading expert on treating HIV. He had no background with phages but when Steff, a friend and colleague, approached him in desperation about using them with Tom, he sprang into action to learn all he could, and to create a network of experts who might provide phages capable of killing Acinetobacter.
"There is very little evidence that phage[s] are dangerous," Chip concluded after first reviewing the literature and now after a few years of experience using them. He compares broad-spectrum antibiotics to using a bazooka, where every time you use them, less and less of the "good" bacteria in the body are left. "With a phage cocktail what you're really doing is more of a laser."
Collaborating labs were able to identify two sets of phage cocktails that were sensitive to Tom's particular bacterial infection. And the FDA acted with lightning speed to authorize the experimental treatment.

Tom's case was scientifically important because it was one of the first times that phages were successfully infused into the bloodstream of a human. Most prior use of phages involved swallowing them or placing them directly on the area of infection.
The success has since sparked a renewed interest in phages and a reexamination of their possible role in medicine.
Over the two years since Tom awoke from his coma, several other people around the world have been successfully treated with phages as part of their regimen, after antibiotics have failed.
The Future of Phage Therapy
The experience treating Tom prompted UCSD to create the Center for Innovative Phage Applications and Therapeutics (IPATH), with Chip and Steff as co-directors. Previous labs have engaged in basic research on phages, but this is the first clinical center in North America to focus on translating that knowledge into treating patients.
In January, IPATH announced the first phase 2 clinical trial approved by the FDA that will use phages intravenously. The viruses are being developed by AmpliPhi Biosciences, a San Diego-based company that supplied one of the phages used to treat Tom. The new study takes on drug resistant Staph aureus bacteria. Experimental phage therapy treatment using the company's product candidates was recently completed in 21 patients at seven hospitals who had been suffering from serious infections that did not respond to antibiotics. The reported success rate was 84 percent.
The new era of phage research is applying cutting-edge biologic and informatics tools to better understand and reshape the viruses to better attack bacteria, evade resistance, and perhaps broaden their reach a bit within a bacterial family.
Genetic engineering tools are being used to enhance the phages' ability to infect targeted bacteria.
"As we learn more and more about which biological activities are critical and in which clinical settings, there are going to be ways to optimize these activities," says Chip. Sometimes phages may be used alone, other times in combination with antibiotics.
Genetic engineering using tools are being used to enhance the phages' ability to infect targeted bacteria and better counter evolving forms of bacterial resistance in the ongoing "arms race" between the two. It isn't just theory. A patient recently was successfully treated with a genetically modified phage as part of the regimen, and the paper is in press.
In reality, given the trillions of phages in the world and the endless encounters they have had with bacteria over the millennia, it is likely that the exact phages needed to kill off certain bacteria already exist in nature. Using CRISPR to modify a phage is simply a quick way to identify the right phage useful for a given patient and produce it in the necessary quantities, rather than go search for the proverbial phage needle in a sewage haystack, says Chan.
One non-medical reason why using modified phages could be significant is that it creates an intellectual property stake, something that is patentable with a period of exclusive use. Major pharmaceutical companies and venture capitalists have been hesitant to invest in organisms found in nature; but a patentable modification may be enough to draw their interest to phage development and provide the funding for large-scale clinical trials necessary for FDA approval and broader use.
"There are 10 million trillion trillion phages on the planet, 10 to the power of 31. And the fact is that this ongoing evolutionary arms race between bacteria and phage, they've been at it for a millennia," says Steff. "We just need to exploit it."
