It鈥檚 hard to imagine a heart attack saving someone鈥檚 life instead of potentially ending it. But that鈥檚 exactly what happened to Jos茅 Aguiar in the summer of 2019.
Jos茅鈥檚 left foot was swollen and painful. He made an appointment to see his primary care physician.
His doctor performed an electrocardiogram. Soon after, the doctor announced to Jos茅 and his wife, Maria, that an ambulance was on its way to take Jos茅 to a hospital.
He was having a heart attack. But this hospital visit would reveal an even bigger problem: a potentially cancerous mass in his colon.
Doctors would need to do a biopsy to determine if the mass was cancerous. But the physicians at the community hospital felt the procedure was too risky to perform given Jos茅’s fragile state.
The medical staff reached out to area hospitals capable of taking on more complex cases. Jos茅 was transferred to 喵咪社区.
One benefit of having access to an academic medical center is that it provides patients with a higher level of care than most community hospitals. Advanced treatments, breakthroughs in research, and access to clinical trials tend to set them apart from other health systems.
Jos茅 also benefited from Keck Medicine鈥檚 approach: A team of doctors centers the treatment plan around the unique needs of each patient. Jos茅 needed a colorectal surgeon, a cardiologist and a podiatrist.
The team triaged his needs, developed a treatment plan and coordinated efforts so they could quickly deal with his most threatening conditions first.
Jos茅 had ischemic cardiomyopathy, a condition caused by a narrowing of the coronary arteries. As a result, Jos茅鈥檚 heart was only operating at about 20%. He also had a blood clot in one ventricle, rendering him too weak for surgery.
A cardiologist with the Heart Failure, Heart Transplantation and Mechanical Circulatory Support Program at Keck Medicine, was up first. To get Jos茅鈥檚 heart strong enough for surgery, a stent was placed in one of his arteries.
鈥淎t the beginning, it was a very time-sensitive situation where a lot of coordination was needed to treat his heart attack and get him well enough to treat his colon,鈥� says the cardiologist.

Within a month, the cardiologist notified Joongho Shin, MD, a colorectal surgeon at Keck Medicine, that Jos茅 was strong enough to undergo colorectal surgery. By this time, it had been determined that the mass in Jos茅鈥檚 colon was cancerous.
When Dr. Shin operated, he discovered there was more to be worried about. Jos茅 had sigmoid colon cancer that had spread to the outer layer of his bladder. This meant bringing in a urologist to help remove part of his bladder.
Though Jos茅鈥檚 colon cancer was stage 3 and had invaded another organ, the fact that he did not know about it is not unusual. Dr. Shin, who is also an assistant professor of clinical surgery at the Keck School, says colon cancer is often asymptomatic or minimally symptomatic. This is why some patients are not aware of it until it is advanced.
Colorectal surgeons at Keck Medicine鈥檚 are accustomed to doing multi-organ resection when colon cancer invades other areas. They work with a multispecialty group of surgeons, such as urologists and plastic surgeons, to remove cancer in various organs.
They also provide reconstruction surgery when necessary and give patients the best shot at survival and high quality of life after cancer.
Jos茅鈥檚 surgery under Dr. Shin was a success. Not only was the team able to remove the cancer from his colon and bladder, but they preserved his colon so he wouldn鈥檛 need a colostomy.
According to Dr. Shin, colon cancer recurs more frequently among patients with more advanced cancer. But adding chemotherapy to patients with stage 3 colon cancer reduces the recurrence rate.
The risk is highest in the first three years after treatment but rarely recurs if a patient survives five years without its return. For this reason, Jos茅鈥檚 team would grow to include a medical oncologist who oversaw Jos茅鈥檚 chemotherapy.
About a year after his heart attack, Jos茅鈥檚 blood sugar levels, which had been high prior to his heart attack, became progressively worse. He was diagnosed with type 2 diabetes mellitus.
Braden Barnett, MD, an at Keck Medicine, joined Jos茅鈥檚 care team. Dr. Barnett, also a clinical assistant professor of medicine at the Keck School, notes that controlling diabetes in and of itself is important.
In this case, he says, effective treatment was critical to Jos茅鈥檚 overall care. Uncontrolled diabetes can strain the heart and make cancer treatments less effective. Two years after his heart attack, Jos茅鈥檚 doctors believe his prognosis is good.
Jos茅 is now cancer-free. Dr. Shin and his medical oncologist are monitoring him for signs of recurrence.
His heart has also improved steadily and is now functioning at a normal rate. The blood clot in his heart cleared from his treatment and his blood sugar, which had soared in 2020, has settled back into a normal range.
Now Jos茅 is back to doing what he loves: Caring for the fish in his koi pond along with his finches and other birds.
