February is American Heart Month, and a Georgia medical expert said knowing the difference between heart attack and cardiac arrest can help save a life.

Every year, more than 800,000 people in the U.S. have a heart attack, and the majority are first-time heart attacks, according to the Centers for Disease Control and Prevention.

Dr. Jaime Burkle, medical director of the Center for Cardiovascular Prevention, Metabolism and Lipids at the Georgia Heart Institute, said cardiac arrest is when a person’s heart stops pumping blood around their body, and they stop breathing. He added circulation needs to be restored immediately with CPR.

He noted one of the causes of cardiac arrest could be a heart attack, which is due to blockage in the circulation in the coronary arteries.

“The coronary arteries supply the heart muscle with blood,” Burkle explained. “And when you have a buildup of cholesterol plaque inside the artery, and then a blood clot, this will interrupt the circulation of blood inside the heart muscle and cause a heart attack, also known as a myocardial infarction.”

Burkle pointed out if cardiac arrest results from a heart attack, which is about 25% of the cases, then it is preventable. He added prevention starts with tackling the risk factors which can cause heart attacks, such as elevated cholesterol and blood pressure, smoking, diabetes and obesity.

Dr. Ravi Johar, chief medical officer for UnitedHealthcare, said a cardiac arrest can happen to a teenager playing baseball, who’s hit by a ball at the exact moment in the heartbeat cycle to disrupt it. He added family medical history and genetics can help determine if someone is prone to experience cardiac arrest or a heart attack. Screening and tests are encouraged for those with high-risk family history.

“Things like Marfan syndrome increases the risk of aneurysms and abnormal blood flow to the heart, and things of that sort,” Johar noted. “There can be some genetic consequences. There can also be genetic history, if your parents had problems with their hearts, there’s a higher likelihood that you may.”

Johar stressed it is important to be aware of some of the most common heart-attack signs including tightness, pressure, or an aching sensation in the chest which can spread through the upper body, plus shortness of breath, fatigue and dizziness.

Georgia Legislature approves coverage to help first responders cope with job-related PTSD treatment

The Ashley Wilson Act, named for Gwinnett police sergeant Ashley Wilson, passed unanimously in the Georgia House of Representatives, aiming to provide supplemental health insurance for first responders diagnosed with PTSD due to on-the-job experiences. This landmark legislation, celebrated for its potential to significantly aid in the recovery and support of traumatized first responders, reflects a broader recognition of PTSD’s serious impact on public safety personnel, promising financial and treatment support beginning January 1, 2025.

FAFSA delays pose challenges for Georgia college-bound students

Students across Georgia are facing delays in the Free Application for Federal Student Aid (FAFSA) process, particularly challenging due to its late January rollout and additional complications for mixed-status families. Despite these setbacks, the Department of Education has implemented fixes for major issues, and officials, including MorraLee Keller of the National College Attainment Network, urge students not to give up on securing financial aid for college.
