A Second Chance at Life: Luis Peñate’s Heart Transplant Journey

From marathon training to life support in a matter of months, a 35-year-old Miami man credits the heart transplant team at Cleveland Clinic Weston Hospital with saving his life.

A Healthy Life, Suddenly Interrupted

At 35, Luis Peñate was the picture of health. The Miami resident ran marathons, ate well, slept well and maintained an active lifestyle. Then, in August 2025, his health changed dramatically.

Luis was initially evaluated at a Miami hospital and diagnosed with myocarditis, an inflammation of the heart muscle. He recalls becoming ill after hand, foot and mouth disease and later contracting COVID-19. His condition continued to deteriorate.

“I was a very healthy individual,” Luis says. “I ran marathons, ate well, slept well, worked a lot. Then everything changed.”

As his heart function worsened, Luis’s father, a local physician, reached out to cardiology colleagues for guidance. Their advice was consistent: take him to Cleveland Clinic Weston Hospital.

Rushed to Lifesaving Support

By the time Luis arrived at Cleveland Clinic Weston Hospital, he was critically ill. His heart function had fallen to approximately 10% to 15% and would ultimately decline to about 5%. He was rushed for advanced treatment and placed on extracorporeal membrane oxygenation, or ECMO, a form of temporary life support that can take over the work of the heart and lungs while a medical team determines the next steps.

Additional evaluation revealed giant cell myocarditis, a rare and aggressive form of heart muscle inflammation. Luis required intensive support and was resuscitated three times as the team worked to keep him alive.

“It was very, very hazy,” Luis recalls. “I wasn’t feeling good. But everybody at Cleveland Clinic was amazing with me.”

Waiting for a New Heart

With his heart unable to recover adequately, Luis needed a heart transplant. He was placed high on the transplant waiting list, but even with that priority, waiting for a donor heart brought uncertainty.

“I think the hardest part was waiting for the heart,” he says. “You don’t know — is it going to be today? Is it going to be tomorrow? Is my body going to hold out this long? That was the hardest part: the unknown.”

Luis says he focused on staying hopeful and holding on until a donor heart became available. He ultimately underwent a heart transplant at Cleveland Clinic Weston Hospital.

“The operation was extremely successful,” he says. “You guys saved my life. You made sure that I could get a second opportunity.”

Back to Running — With a New Perspective

Luis describes his recovery as strong and says he is now about 90% back to his normal activity level. He has returned to running, playing basketball and spending time with his family.

But the transplant changed more than his physical health. It changed how he thinks about time.

“Before, I was 100 miles an hour all the time,” Luis says. “Now, I think things through a little bit more. Time is very, very valuable to me.”

Today, he prioritizes being with his children and parents, particularly his father, whose advocacy helped guide him to Cleveland Clinic during the most critical period of his illness.

“I’m really grateful that not only you guys saved my life, but now you’ve given me a second chance,” Luis says.

Advanced Care for a Rapidly Failing Heart

Luis’s story highlights the continuum of advanced heart failure care available at Cleveland Clinic Weston Hospital — from rapid evaluation and temporary mechanical circulatory support with ECMO to transplant evaluation, donor-heart transplantation and post-transplant recovery. In his case, that ability to escalate care quickly was especially important because giant cell myocarditis can progress rapidly and cause severe heart failure.
