Reina's dressed for her Zumba class, ready to go. As each classmate walks in, she hugs them. "Thanks for celebrating my birthday with me!" She flashes her electrifying smile: "I'm two today."

Reymita Walls—known as Reina—isn't two. She has an 18-year-old daughter, an adult son, and is a grandmother of three. But two years ago the Metropolitan Utilities District employee collapsed in a hallway at work minutes after walking in the door. When co-workers spotted her, she didn't have a pulse and she wasn't breathing.

Panic followed. Employees who saw her every day—most of them good friends--couldn't believe she was on the floor, lifeless. Some were crying. One started CPR. Another called 911. Others prayed. "Reina, stay with me!" one pleaded. In the chaos, someone ran and came back with an AED, an automated external defibrillator that had been hanging unused in the lunchroom.

He applied the AED pads to her chest and the commanding voice on the machine announced, "Shock is advised." He shocked her. Her body jerked, then settled back on the tile floor, "She was just laying there. She was just still," one co-worker remembers. "We're yelling, 'C'mon Reina!'" They applied a second shock. By then the EMTs were in the building and checking her. "We have a pulse!" one announced. But in the ambulance she needed a third AED jolt.

Reina was having a heart attack. Like many women, she missed the signs because she didn't have the telltale chest pain that men often experience. The few days before her heart attack, she'd been achy and fatigued. When she walked fast she found it hard to breathe. Two days before, she'd tried to work out on the treadmill at the gym. She felt tired and sat down, telling her daughter to go ahead without her. She blamed the way she felt on a nasty flu and bronchitis and when she went to work that Monday morning she still wasn't feeling right. A friend told her later they had a phone conversation. She doesn't remember it. She was running late to work. She doesn't remember. She climbed the steps and entered the building. She doesn't remember that either. "I knew I wasn't right. I thought I'd be like that forever."

No one—especially Reina—ever expected her to have a heart attack. She was trim, worked out, took good care of herself and had no history of heart attacks in her family. One co-worker called her "the epitome of health." Her daughter couldn't believe the news when she received the emergency call at school. "But she just kissed me goodbye," 16-year-old Natalia insisted. "She never gets sick."

Natalia rushed to Alegent Creighton Health Bergan Mercy Hospital from Central High School, where her mom had dropped her off a short time before. Anxious co-workers waited with her. The cardiologists found a clot had formed in one of Reina's main arteries of the heart, blocking her blood supply. She had what's commonly called a "widow-maker" because it can be so devastating. The medical team rushed to implant a tube called a stent, which props open the artery. Reina doesn't remember any of it.

The realization that she had "died" was even more terrifying. "The first thing that came to my mind was leaving my daughter." Reina says the two are very close. "She's very strong but I thought of her (Natalia) being by herself. And my not being able to see her graduate and have children—or see my son and his children, my grandchildren. I wouldn't be able to see any of them anymore."

Today Reina says: "People ask me, 'Did you see the light?' It was like I went to sleep and was dreaming. All kinds of things were happening in my dream. But I can't remember what it was about." She does remember the excellent care she received. "Alegent Creighton Health is the best. When you are going through a crisis, you want the best team. I have visited almost every Alegent Creighton Health location since then and the doctors and nurses are attentive, friendly and make you feel they truly care." She says she loves the lullaby that's played overhead when a baby is born in the hospitals. "It makes your heart feel good to hear life." She's also fond of her cardiac rehab staff in Papillion. "They're the best. I stop to see them whenever I'm at that location." She laughs when she talks about the staff at Lakeside Hospital: "The nurse that signs you in is hilarious. She told me if I could not say 'Ramachadran' (the cardiologist's name), I could not see him. I learned to say his name correctly fast."

For seven months, Reina considered herself "blessed" to still be alive. But then she started having the same worrisome symptoms—fatigue and trouble breathing. "I knew something was wrong. But then I'd think, 'I'm being silly--no way is it my heart again.'" She consulted her cardiologist, Atul Ramachandran, M.D., who had told her early on she didn't look like the typical heart patient and she was lucky she had her heart attack at work, where her co-workers came to her rescue. Dr. Ramachandran says he took Reina seriously when she complained about recurring symptoms even though it's not unusual for heart attack patients to experience anxiety. Dr. Ramachandran told Reina she could either do a stress test or a cardiac catheterization to evaluate her symptoms.

Because of the severe recurrent symptoms, Dr. Ramachandran told her, "If the stress test came back normal I would believe you over the stress test." He asked her if she wanted a cardiac catheterization, a procedure that involves a thin hollow tube going into the heart for a closer look. She said yes. The procedure showed there was a site of 90 percent of renarrowing within the stent, something Dr. Ramachandran says can happen 15 to 20 percent of the time. She was a candidate for another heart attack. Reina praises Dr. Ramachandran: "I found a doctor who cared and listened. If my doctor hadn't listened to me, I probably wouldn't be here today."

Dr. Ramachadran applauds Reina for recognizing what was happening to her—and acting on it. He also says it's important for women to know the signs of a heart attack are different than those for men. Women are more likely to experience unusual fatigue, sleep disturbances, shortness of breath, indigestion and anxiety.

During the recent flu outbreak this winter, Reina started worrying again because she had the familiar symptoms of a heart attack. But her ailment turned out to be the flu. "I still kept asking my doctor, 'Are you sure? Are you sure it's the flu? Are you sure?'"

She still can't believe she had one heart attack—and was close to having a second. "Before when people had heart attacks, it was sad but it didn't really affect me." Now it hits her how important it is to be informed. She's watched a video over and over that American Heart Association put together telling her story. "I cried and cried and cried and cried."

Her daughter isn't forgetting either. Reina says, "If I don't answer the phone, she'll call me back right away. Sometimes in the morning she'll stop by my room and just look at me. Or she won't let my hand go." Natalia is18 now and lives at home. She'd talked about going to college in Virginia but chose to go to UNO, to be close to her mom. "She tells me, 'Mom, don't die!' I promise her I won't."

Reina is conscientious about seeing her doctors and just had a stress test. Again, she raves about the Alegent Creighton Health employees: "Jeff and Stephanie at Bergan Mercy Nuclear Imaging were awesome. Stephanie loves her job and gives the best care tips to make sure her patients stay healthy. When Jeff saw I was cold, he ran off to get me a toasty warm blanket."

Reina's always worked out but now she's a regular in Zumba class, including one she organized at MUD for co-workers. MUD and its hundreds of employees also celebrate National Wear Red Day.

She's started a 501(c)(3) non-profit organization called Healing Tender Hearts that urges women to listen to their hearts. "Women tend to put our jobs, children and homes first. We put everything before our own health. We can't do that."

Healing Tender Hearts will focus on education and will provide scholarships for students pursuing cardiology or rehabilitation work. She's raising money through "Zumba Takeovers" across the city. "I've always believed in God, in a higher power. He saved me for a reason. He saved me to save other people," Reina says.

She thinks back to that wintry morning when she died on the tile floor in the narrow hallway and was revived. "This is something I want to do, something I have to do. When my life is over, I want God to say, 'Job well done!' I want to have made a difference."

Reina's next "Zumba Takeover" is April 13th at the South Omaha YMCA from 2 to 5 p.m. It's a family Zumba party, with Zumba for children, as well as other activities for kids.
