PHOENIX – Marcie Westwater was at work when she had an odd feeling in her chest with hot and cold sensations. Those feelings turned out to be a spontaneous coronary artery dissection – a condition that can be fatal if not diagnosed and treated quickly.

She told her husband Mark, who works in the same Central Phoenix office, that she wasn’t feeling well.

“I asked my husband if he could take me home to rest. By the time he brought the car around, I was having a difficult time walking. I crawled into the back seat and said take me to the Heart Hospital,” said Westwater.

She knew that nearby Abrazo Arizona Heart Hospital was where she needed to be.

“He got me to the Heart Hospital, where I coded in the parking lot. They put me on a gurney and started doing chest compressions and used the defibrillator on me three times and then two shots to the heart,” said Westwater.

Spontaneous coronary artery dissection, or SCAD, is a result of a tearing in the coronary artery wall that happens without warning. Blood can become trapped and bulge inward blocking the artery, causing a heart attack because blood flow can’t reach the heart muscle, according to the American Heart Association.

Dr. Akil Loli, an interventional cardiologist who specializes in Structural Heart Disease, was on duty at Abrazo Arizona Heart Hospital. He quickly assessed and diagnosed Westwater’s condition.

“After asking my husband a few questions Dr. Loli said, ‘I know what it is.’ “ said Westwater.

SCAD occurs most often in women in their 40s and 50s, although it can happen in men and people of nearly any age. Researchers say that physical and emotional stress is commonly reported in women who otherwise may show or have no cardiovascular risk factors prior to the condition occurring.

As someone who makes fitness a priority, a heart problem caught Westwater, 54, by surprise. “I had a friend of a friend who had been a patient at Abrazo Arizona Heart Hospital, so that was always kind of stuck in the back of my mind. If you have a heart problem, that’s where to go.”

Healthcare professionals say it’s important to recognize the signs of a heart attack and act quickly. The signs may include chest pain or pressure, shortness of breath, profuse sweating and dizziness. And women may have more subtle signs. Calling 911 may save your life.

“I didn’t present with any of the textbook signs. A lot of times people may think it’s just a panic attack. Obviously Abrazo didn’t. This was incredible. I felt like I was getting individualized care, and very nurtured. I can’t say enough good things about Dr. Loli, and the nurses were incredible. Not only did the nursing staff make sure I was taken care of, they took care of the people that were visiting me so that I could get better.”

Abrazo Arizona Heart Hospital, 1930 E. Thomas Road in Phoenix, opened in 1998 as one of the first hospitals in the U.S. dedicated to cardiovascular care and research. It continues to be to the forefront of bringing medical advances to the Valley.

“I have so much to be grateful to them for getting me back on my feet, to do all the things that I love to do with my active lifestyle and back to my family and friends. I couldn’t have chosen a better medical team,” said Westwater.
