Many individuals mistakenly believe that cardiac arrest and heart attacks are the same thing, although they are not.
A heart attack happens when blood flow to the heart is impeded, whereas sudden cardiac arrest occurs when the heart malfunctions and stops pumping unexpectedly.
Both are dangerous illnesses, but 70 percent to 90 percent of people who suffer from sudden cardiac arrest die before they reach the hospital. According to the Centers for Disease Control and Prevention (CDC), cardiac arrest is a public health problem with a high rate of occurrence and a serious impact on human health and well-being. In 2015, around 357,000 persons in the United States experienced out-of-hospital cardiac arrest (OHCA).
A new study from the Victor Chang Cardiac Research Institute may soon allow families all over the world to find out if they have genetic abnormalities that cause sudden cardiac arrest, a life-threatening disorder that kills 9 out of 10 people.
Researchers at the Institute have devised a novel electrical test that can screen hundreds of gene mutations in order to find the particular mutations that are damaging to the heart in people with inherited heart diseases syndromes, which can lead to sudden death.
The result represents a huge leap forward in the accuracy and precision of genetic testing, with far-reaching implications for a wide range of neurological problems, as well as muscular and renal diseases.
