The Century Old Heart Test That May Predict Sudden Cardiac Death<\/span><\/strong><\/span><\/h2>\n

The Century Old Heart Test That May Predict Sudden Cardiac Death: It was a typical day for 43-year-old traveling nurse, Lynn Howard. She was visiting a patient at their home when she suddenly felt dizzy and lost consciousness. The Buffalo native woke up a few days later in a hospital bed with a breathing tube.<\/span><\/p>\n

Earlier this month, the mother of three suffered a sudden cardiac arrest \u2013 a condition so deadly that more than 90 percent of people don\u2019t survive. Clinically, she died. But luckily for Howard, the patient she was caring and her husband were paramedics. They started CPR and saved her life.<\/span><\/p>\n

\u201cI can’t wrap my brain around it still, I had no health problems before this,\u201d said Howard. \u201cI was at the right place at the right time with two paramedics right in front of me. It’s the only way I survived.\u201d<\/span><\/p>\n

Unlike a heart attack which occurs when one or more coronary arteries are blocked, a sudden cardiac arrest occurs following a short circuit in the heart. According to the American Heart Association, this electrical problem strikes more than 350,000 people each year\u2014about 1,000 every day.<\/span><\/p>\n

The only way to prevent a sudden cardiac arrest is with the use of an implantable defibrillator which shocks the heart back to a normal rhythm. Until recently, no test can predict when a sudden cardiac arrest will happen and who\u2019s at high risk for needing a defibrillator.<\/span><\/p>\n

\u201cBy the time cardiac arrest happens, it\u2019s way too late,\u201d said Dr. Sumeet Chugh, associate director of Genomic Cardiologyat Cedars-Sinai Heart Institute. \u201cEvery minute that passes there’s a ten percent chance of dying. Ten minutes and you’re gone.\u201d<\/span><\/p>\n

For decades, Chugh has been working to solve the problem of predicting the unpredictable. Now, after studying thousands of patients, he has discovered a solution that involves an inexpensive century old test called an electrocardiogram, or EKG, which displays the heart\u2019s electrical activity.<\/span><\/p>\n

Chugh looks at six data points on an EKG tracing that reveals important information ranging from how fast the heart is pumping to its electrical activity. This key information is then used to assign a risk score ranging from zero (normal) to six (severe). A score above four indicates a 20-fold increase in the risk of suffering a cardiac arrest requiring a defibrillator.<\/span><\/p>\n

\u201cHalf the patients who are going to have a sudden cardiac arrest, will have some kind of warning while the other half won’t,\u201d said Chugh. \u201cImagine half of them are going have a cardiac arrest as the first unexpected sign of heart disease.\u201d<\/span><\/p>\n

The hope is that in the future, anytime a patient receives an EKG at a doctor\u2019s office, it will show their risk of having a sudden cardiac arrest, according to NBC News Medical Correspondent Dr. John Torres. If the score is high, then a person will be referred to a cardiologist for further evaluation which may require an implantable defibrillator, even if they are currently healthy.<\/span><\/p>\n

Howard didn\u2019t know she was at risk. She had a clean bill of health her entire life and never imagined that a defibrillator would be implanted in her chest. She\u2019s back home now, getting stronger every day, and thankful for the quick thinking of those two paramedics.<\/span><\/p>\n

\u201cI feel so grateful for a second chance at life,\u201d said Howard. \u201cHaving your risk profile assessed is important; anything to prevent this from happening to at least one person would be great.”<\/span><\/p>\n
