Around 805,000 Americans suffer from heart attacks annually, averaging to one in every 40 seconds. 75 percent of these people have reported the attack to be their first one. It makes the situation difficult for them to act promptly in response to the symptoms. Besides, silent heart attacks (SMIs) account for around 45 percent of heart attacks. It means that there are high chances of heart attack patients mistaking the attack with a case of indigestion or flu.
How to Diagnose a Heart Attack?
A “classic” heart attack often comes with symptoms like arm and chest pain, shortness of breath, and nausea. However, the symptoms are not equal in all cases, particularly in SMIs. At times, even an EKG fails to detect a silent myocardial infarction.
Left Ventricular and Diastolic Pressure (LVEDP) is a vital indicator of heart health. Researchers have been trying to develop biomarkers, which can help them measure the hemodynamic index referred to as LVEDP.
When LVEDP goes up, the chances of having a heart attack increases. However, LVEDP reflects the pressure within the closed chamber of the heart, which can only be measured by putting a catheter. This process is highly invasive.
Smartphone – The Savior
A smartphone can not only save the process from being highly invasive but also can help people detect early signs of silent heart attacks. Once the researchers understand the pressure and wave flow dynamics within the heart, they can extract necessary information from the waves and the information will be shown on the screen of the smartphone in the process.
Ultimately, the phone will be able to provide a person with the readings regarding the pressure inside the heart.
According to the American Heart Association, every minute after a heart attack is vital. For every minute a person waits between the time they feel the symptoms to the time they receive the treatment, heart cells could be dying irreversibly. This monitoring device can help people monitor their heart health on the go, and can help them save every precious second to get rid of a heart attack.
