Cardiologist answers some of the top heart health questions on Google for American Heart Month
People are curious about heart health — and for good reason.
Heart disease remains the leading killer of men and women in the U.S. — each year, around 695,000 people die from cardiovascular conditions, per the Centers for Disease Control and Prevention (CDC).
For American Heart Month, Dr. Martha Gulati, M.D., a leading Cedars Sinai cardiologist and president of the American Society of Preventive Cardiology, is sharing some of the most commonly googled questions about heart health, according to Google Trends.
TWO WOMEN WITH HEART DISEASE HAD TO FIGHT FOR A DIAGNOSIS. HERE’S HOW THEY ADVOCATED FOR THEIR HEALTH
Below are the questions — followed by the doctor’s answers.
Did you ever wonder about these issues? Take a look.

‘What is heart arrhythmia?’
Heart arrhythmia occurs when there is an abnormality in the rhythm of the heartbeat, said Gulati.
“This means your heart either beats too fast, a condition known as tachycardia, or too slow, also known as bradycardia, or irregularly,” she told Fox News Digital.
Arrhythmias can be triggered by genetics, stress, pre-existing heart conditions, or lifestyle habits such as smoking and poor diet.
They can affect people of all ages, Gulati noted.

“The most common type of arrhythmia is atrial fibrillation, also known as AFib,” she said.
“AFib is an irregular and often rapid heart rate that can increase the risk of stroke, heart failure and other heart-related complications.”
Around 12.1 million people in the U.S. are expected to have AFib by 2030, according to the CDC.
‘What are the symptoms of heart arrhythmias?’
Heart arrhythmias can have very different symptoms depending on the type of arrhythmia, the severity and the health of the individual, according to Gulati.
Symptoms of a cardiac episode can include chest pain, discomfort, fatigue and dizziness.
“Although these symptoms are alarming and can certainly induce anxiety, it’s important to know when they require an urgent hospital visit,” the doctor said.

One challenge of arrhythmia symptoms is that they can come and go, she said.
“Sometimes, a patient makes an appointment or comes to the hospital after experiencing a cardiac symptom and, by the time they speak with a doctor, their symptoms have abated,” said Gulati.

“It is difficult to treat patients who are no longer presenting with the symptoms they experienced, and it can be frightening or frustrating for patients who just want to understand what is going on with their bodies.”
Medical-grade personal digital health tools can help break this cycle, she said; they allow patients to access accurate, real-time heart data that they can share with their physicians.

“For patients, these tools can provide additional peace of mind and insight into their heart health,” Gulati said.
“For health care providers, they offer a more comprehensive understanding of a patient’s condition and enable us to potentially implement more timely interventions.”
‘What are heart palpitations?’
These are typically characterized by a rapid, fluttering or pounding heartbeat and can often be felt in the chest, throat or neck, according to Gulati.
Triggers of palpitations can include stress, anxiety, hormonal changes or stimulants like caffeine.
“Heart palpitations on their own aren’t always a cause for alarm,” said Gulati.

Patients can purchase home devices online that allow them to easily record symptoms, receive a reading and confirm whether they are experiencing a potentially life-threatening arrhythmia, the doctor noted.
“However, if you experience heart palpitations coupled with chest pain, fainting or severe dizziness, it is important to seek immediate medical attention,” she added.
‘What causes heart arrhythmias?’
Heart arrhythmias can have a myriad of symptoms — plus a variety of causes.
Lifestyle habits such as activity level, diet or smoking can have a serious impact on overall wellness, particularly heart health, Gulati noted.

“As health care providers, we stress the importance of a good diet and daily exercise, because it keeps your heart in good shape and reduces the risk of heart disease,” she said.
There are some uncontrollable factors that can contribute to arrhythmias, however.
“One of these is abnormalities in the heart structure, which tend to be congenital, meaning something you’re born with,” Gulati told Fox News Digital.
“Age-related changes can affect the way our hearts operate and the way electrical impulses flow through our cardiovascular system.”
“Congenital heart conditions can impact the way electrical activity signals travel through the heart, which can then impact the heart’s rhythm.”
Age-related changes can also make people more susceptible.
“If you experience heart palpitations coupled with chest pain, fainting or severe dizziness, it is important to seek immediate medical attention,” a cardiologist said. (iStock)
“As we age, our hearts change,” the doctor said. “These age-related changes, though natural, can affect the way our hearts operate and the way electrical impulses flow through our cardiovascular system.”
It’s important to understand the specific factors that contribute to arrhythmias in order to get proper diagnosis and treatment, according to Gulati.

“While lifestyle choices can influence overall health, managing aging and congenital or genetic factors often requires a multifaceted and personal approach,” she said.
“The more proactive you are about your heart health, the better. Regular check-ups and monitoring can help identify and manage these factors.”
‘What are arrhythmia treatments?’
Treatments for arrhythmia will differ depending on each individual’s symptoms and contributing factors, Gulati said.
“It’s important for your doctors to have access to as much information as possible so they can make the most informed decisions about your care,” she said.

Early detection and intervention can significantly impact the long-term prognosis and reduce the risk of complications, such as stroke or heart failure, the doctor noted.
“That’s why I stress the importance of providing real-time data to physicians about what you’re experiencing when you’re experiencing it,” she said.
“This not only fosters a deeper understanding of your unique circumstances and needs, but it also allows your doctor to tailor treatments based on day-to-day insights.”

More than three-quarters of the global population is falling short on omega-3 intake, a nutrient gap that may increase the risk of heart disease, cognitive decline, inflammation and vision problems.
That’s according to an analysis published in Nutrition Research Reviews, in which researchers from the University of East Anglia, the University of Southampton and Holland & Barrett analyzed omega-3 intake patterns across multiple countries and age groups.
The review found that 76% of people worldwide are not meeting the recommended levels of two omega-3 fats that are essential for heart health: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
TREATING GUM DISEASE COULD REDUCE RISK OF HEART ATTACKS AND STROKES, STUDY SUGGESTS
The analysis considered recommendations from global health authorities and assessed how closely populations follow them.
Most adults should aim for at least 250 milligrams of EPA and DHA per day, though actual intake is far lower in many regions, according to the researchers.

To explore the health implications of low omega-3 intake, Fox News Digital spoke with Michelle Routhenstein, a New York–based preventive cardiology dietitian at Entirely Nourished.
HIGH-POTASSIUM FOODS COULD ‘SIGNIFICANTLY’ LOWER RISK OF HEART FAILURE, STUDY FINDS
Low omega-3 levels can have a noticeable impact on heart health, cognitive function and inflammation throughout the body, the expert confirmed.
Low intake can also increase the risk of heart attacks and sudden cardiac death, she added. It’s also associated with higher triglycerides, irregular heart rhythms and plaque in the arteries.

Inadequate omega-3 levels have also been linked to changes in brain function, including faster cognitive decline, a higher risk of Alzheimer’s disease and increased rates of depression.
Routhenstein noted that low levels may also worsen inflammation in autoimmune conditions such as psoriasis, and can negatively affect eye health, since omega-3s play a key structural role in the retina.
SITTING ALL DAY? NEW STUDY SAYS CERTAIN FOODS MAY PROTECT YOUR HEART FROM DAMAGE
To improve omega-3 levels, the expert said it’s important to understand how much is needed and where to get it.
“The richest dietary sources of EPA and DHA are oily fish, such as salmon, mackerel, sardines, herring, trout and anchovies,” Routhenstein told Fox News Digital.

Many people benefit from eating oily fish more frequently, often three to four times per week, Routhenstein noted. For individuals who do not eat fish regularly, supplements can help raise EPA and DHA to healthier levels.

For those taking omega-3 supplements, dosing should be based on lab results, medications, omega-3 levels and overall medical history, according to Routhenstein. Moderate, quality-controlled supplements are generally considered safe for most people.

There is also some evidence supporting prescription-strength omega-3 products.
“High-dose EPA, such as 4 grams per day of icosapent ethyl, has been shown to reduce major cardiovascular events in certain high-risk populations, while similar doses of mixed EPA/DHA have not consistently shown the same benefit,” Routhenstein said.
Omega-3 dosing should be individualized based on lab data, medication use, current levels and overall medical history. (iStock)
Testing omega-3 levels can also help determine whether intake is adequate. The omega-3 index, a blood test that measures EPA and DHA in red blood cells, is considered one of the most reliable ways to assess status.

“Levels around 8% are associated with lower cardiovascular risk, while levels below approximately 4% are considered low,” Routhenstein said.
Understanding baseline levels can help guide more personalized decisions about diet and supplementation.

As winter weather moves in, cozy essentials like scarves, plush throws and heated bedding become everyday comforts.
But dermatologists caution that these cold-weather favorites can secretly undermine skin health — trapping sweat and bacteria, causing irritation and exposing the skin to excess heat.
Choosing the right materials for wellness — and using them safely — can make a big difference.
VIRAL ALL-WHITE WELLNESS PUSH COULD BOOST MENTAL HEALTH — HERE ARE 4 ESSENTIALS TO CONSIDER
Here are five winter must-haves and gift ideas, with expert tips on how to keep skin healthy and happy while staying warm this season.
Soft scarf, $19.99, Amazon.com

A soft scarf is a staple for cold days and an easy way to elevate a winter outfit.
Yet, if breakouts are appearing along the neck, jawline or chest, that favorite accessory may be part of the problem.

“You should wash your scarf as often as your clothes to prevent breakouts,” Annabelle Taurua, a beauty expert at Fresha, a beauty and wellness booking platform headquartered in London, told Fox News Digital.
Cotton is a better choice than polyester, she also noted, as it’s more breathable and allows sweat to evaporate.
Fluffy blankets, $28.97, Potterybarn.com

She also said it’s best to avoid direct contact for long periods to reduce irritation.
Hot water bottle, $12.99, Amazon.com
A traditional winter staple, hot water bottles offer quick comfort — but they come with risks similar to heated blankets, including burns, scalding and long-term heat-related skin damage.
Hot water bottles should never be filled with boiling water, experts advise. (Amazon)
“Never fill a hot water bottle with boiling water,” Taurua said.
“Only use hot, not boiling, water, and fill it to a maximum of two-thirds.”
