An orphan turned out to be a life-saving inventor

Marisa became an orphan after her mom's sudden death. As an orphan, Marisa was left with nothing but became an inventor of a life-saving device.

“I am proud I could make a difference in people’s lives and impact those who are dependent.”

At a young age of 13, Marisa Redfield lost her mother to one of the deadliest things to mankind – Heart Attack.

Orphaned and lost, she was shown love and provided by the orphanage despite them not being blood related. Marisa became inspired by the kindness shown and have decided to contribute back to society.

At 30, she successfully established a seniors care home for those who have a history of, or have battled a heart attack.

It Happened again

Until one cold, quiet night, the unexpected strikesHeart attack took the life of someone Marisa cares for. 

And he is only 34.

“I’m in shock. I am aware that it can happen to anyone." 

“But he’s always active and never drinks nor smokes.”

 -  Marisa

Derek, a night shift nurse was found dead on the outdoor compound. CCTV footage previewed that Derek collapsed abruptly. He couldn’t even call out for help, he looked painful.

This led Marisa to her devastation, thinking she is doing everything she could.

The fight against heart attack

Surging with determination, she was moved with a new devotion.

“NOT on my watch. Never again.”

She decided that the only way a victim can be saved, is by tracking their heart activity, and alert them of early signs of heart attack. In that way, the victim can act before it is too late.

Marisa studied to a great degree to understand the heart, met researchers from Germany and worked across various labs to produce a promising solution.

A heart attack is akin to that of a road closure – it leads to an unwanted bottleneck that results in heavy traffic. Long term blockage can permanently damage the heart.

She discovered that before the heart goes into shock, it starts contracting faster. A hormone known as cortisol rises and causes a surge in blood pressure. This may very well be the answer to detecting an impending heart attack as these changes in heart activity can be tracked.

Invisible But Not Invincible

After 2 years, Marisa uncovered the right technology to perform just that.

She successfully devised a non-invasive, inexpensive, portable, and wearable device known as the Haert™ smartwatch. It is a medical grade heart monitor that collects and analyses data, which will then be measured to indicate the vitals of the wearer.

“If only I had this technology 20 years ago, my mother could have been survived.”

Started with a life saved

Marisa made it a practice that everyone in the care centre should be wearing the device. Weeks after, an elderly was detected of an incoming heart attack. and was sent to an emergency ward to receive immediate treatment.

“That device of yours is nothing I have ever seen before.”

“It literally saved your life! There will be nothing we can do to save you, if it was 2 minutes later.” – the heart surgeon

Marisa was so touched when she was told the device saved life.

“I’m welling up with tears of joy! I am finally making a significant impact in people’s lives!” – Marisa

Dr. Selina, a cardiology specialist caught wind of the news on Haert™ and reached out to Marisa to conduct several experiments on her patients. Dr. Selina determines that Haert™ not only detects incoming heart attacks, but monitors the user’s blood pressure, heart rate, and blood oxygen levels with impeccable accuracy.

“Even if they do get to hospital by chance, they might have to go through one or more of the set time-consuming, expensive tests such as the electrocardiogram (ECG).”

“The probability of survival decreases by 7 to 10 percent for every minute that a victim stays in a life-threatening arrhythmia. When it comes to heart attack, every second counts.”

“This makes Haert™ the best solution by far.” – Dr. Selina

A smartwatch, but not ordinary smartwatch

With a push of a button, the wearer can be notified if they’re safe or if a medic’s presence is required. 

Haert™ is developed to be compatible with any smartphone, both Apple and Android OS.

Equipped with a user-friendly interface, it is suitable for the non-tech savvy.

Despite all age, it was designed to serve all.

A user's testimonial

“I was given a second chance, thanks to the device.”

“I intended to get the smartwatch just to track on my daily steps.”

“Recently on a jogging session, I accidentally clicked and detected abnormality of my heart beats. I did not care much. I felt a little tired but was feeling pretty energized so thought I could go on.”

“Then I remembered you don’t always feel the exact symptoms. My wife dialed 911 and I was sent to hospital, I went into cardiac arrest. Luckily the paramedics managed to stabilize my heart.”

“Honestly, without the heart monitor function, I would not be here today to tell everyone about this.” - Joseph


Nearly 8 million people lost their fight to heart attack every year. If you experience chest pain, arm pain, shortness of breath, fatigue, you’re at a higher risk of heart attack.

If treated late, stroke can be a plausible outcome, and any later may result death.

Statistics have proven that all heart attack cases occur 90% of the time at night. This dictates that most seniors wake up in sheer agony and dies in pain and shock.

Many were left to die alone in the dark. Senior users report worrying less and feel safer about their health security.

"I am staying alone and my daughter always has to worry about me. With this watch she can worry less now." - Desmond M

"Not only it can be used to monitor heart rate's abnormality, it can also track our sleep quality. I felt more healthy than ever." - Kelly K

“I don’t feel as vulnerable anymore knowing I’ve got an eye on my heart.” – Ciara B

Heart Attack Is Like A House Fire, The Longer It Takes To Put It Out, The More Structural Damage Is Done

When we look at our progress at cardiac health care today, it is more of sick care than preventative self-care and technology. We should NOT wait for heart attack to occur and pour a vast majority of resources into post care treatment.

Do it for your family. Do it for yourself.
