Coronary artery calcium (CAC) scores have emerged as a pivotal non-invasive tool, enabling healthcare professionals to accurately gauge the accumulation of plaque within a patient’s coronary arteries. However, an important question remains: how effective are these scores in detecting high-risk profiles for heart attacks and mortality among women, in addition to men?
In a groundbreaking study led by researchers at Intermountain Health in Salt Lake City, it has been established that CAC scores are not only proficient at identifying individuals at risk for future heart attacks but also effectively predict mortality. Significantly, the research also revealed that risk prediction based on CAC scores is equally robust for women as it is for men.
The coronary artery calcium score appears to be an excellent and accurate indicator of health and overall prognosis, even beyond heart disease.”

Findings from the pivotal Intermountain Health study were unveiled at the American Heart Association National Scientific Sessions 2024 in Chicago on Monday, Nov. 18, 2024. This presentation is set to draw attention and stimulate further research discussions.
Coronary artery calcium testing is becoming increasingly prevalent in cardiac healthcare due to its non-invasive nature, minimal radiation exposure comparable to that of a mammogram, and affordability when contrasted with more invasive procedures like PET stress tests, coronary CT angiograms, or coronary angiography.
For the Intermountain Health study, researchers meticulously examined the electronic health records of 19,495 women and 20,523 men who had undergone PET/CT scans due to suspected heart disease risk, specifically targeting those who had not yet experienced heart events such as heart attacks.
Of these patients, 7,967 recorded a CAC score of zero, indicating no calcified plaque present in their coronary arteries. Notably, in this cohort, women were generally older than men, with average ages of 60.5 years for women and 53.8 for men. This aligns with established patterns where women typically manifest heart disease at a later stage in life, a point emphasized by Dr. Anderson.
Researchers subsequently conducted a follow-up on patients approximately two years later. Their analysis revealed that a zero CAC score reliably predicted a low risk for both coronary death and nonfatal heart attacks among both genders. Interestingly, zero CAC scores were more commonly observed in women despite their greater average age.
Intermountain researchers also determined that individuals with a zero CAC faced a threefold reduction in the risk of all-cause mortality or heart attack in both men and women. This finding underscores the potential significance of CAC scores as indicators for broader health outcomes.
“We will be exploring this further to understand better why a zero-calcium score is such a good signal to overall health,” said Dr. Anderson, indicating a commitment to advancing research in this impactful area.
Coronary Artery Calcium Scores: The Surprising Heart Heroes!
Ah, the ever-elusive coronary artery calcium (CAC) score—those little numbers that tell us more about our hearts than a bad date with someone who just won’t quit talking about their ex. But let’s get serious, shall we? This new study from Intermountain Health in Salt Lake City is here to set the record straight; it turns out seeing your arteries on an X-ray is all the rage now! Truly, if arteries could talk, they’d be singing, “I Will Survive” in the waiting room.
So, what’s the scoop? The study indicates that CAC scores are not just good at telling men if their hearts are headed for mischief; they’re equally effective at letting women know they’re in for a roaring game of “Will it be a heart attack or just a really exciting day?” The findings were dropped at the American Heart Association National Scientific Sessions—because nothing says “party” like a medical conference in Chicago!
“The coronary artery calcium score appears to be an excellent and accurate indicator of health and overall prognosis, even beyond heart disease.”
What Do These Scores Actually Mean?
These non-invasive tests are the heart-health equivalent of a politer alternative to a colonoscopy—no one enjoys it, but everyone knows it’s supposed to be good for you. According to this new research, CAC scores tell us not only about the build-up of plaque in our arteries but also provide insight into our likelihood of croaking from anything else in life. Turns out that a zero CAC score is like having a golden ticket. No plaque? No problem! You know, like the feeling you get when you find out your ex hasn’t moved on.
Now hold onto your stethoscopes, because here’s the kicker: while effective in flagging up women who might not have their cardiac act together until later in life, researchers have discovered that women were actually more likely to score zero on the CAC test, despite being older on average. So, ladies, it seems you’re not just the better half; you can even outshine the gentlemen in artery cleanliness! It’s almost like finding out you have better odds at the lottery than you thought; who doesn’t love a surprise win?
Follow-Up: The Two-Year Shakedown
Speaking of surprises, nearly 2 years after testing, those with a CAC score of zero were found to be three times less likely to experience a heart attack or other dire events! So when in doubt, keep calm and CAC score on because nothing spells ‘healthy’ like a score of zero. Let’s face it; we need to engage in more activities that keep our hearts pumping joyfully rather than erratically running like a headless chicken!
Final Thoughts: A Heartfelt Future
But wait, there’s more! Dr. Anderson hinted at further exploration about why a zero score is such a stellar predictive marker not just for heart health but all-around health. What’s next, a CAC score that tells you if your coffee is too strong, or if you should really stop scrolling through social media at 2 a.m.?
So, as we dive deeper into the world of coronary artery calcium, let’s embrace the knowledge that the numbers can be more than just numbers—they represent life’s choices and health journeys. So, my friends, if you happen to find yourself face-to-face with a CAC score, just remember: zero may very well be your new hero. Now let’s all raise a glass of low-fat, low-carb, heart-loving smoothie to that!

How do coronary artery calcium scores compare to traditional heart disease screening methods in terms of invasiveness and effectiveness?
**Interview with Dr. Jeffrey L. Anderson on the Impact of Coronary Artery Calcium Scores**
**Editor:** Good afternoon, Dr. Anderson! Thank you for joining us today to discuss your recent findings on coronary artery calcium (CAC) scores.
**Dr. Anderson:** Thank you for having me! It’s a pleasure to be here.
**Editor:** Your study at Intermountain Health suggests that CAC scores are effective in predicting heart attack risk and mortality, particularly for women. Can you summarize why this is significant?
**Dr. Anderson:** Absolutely. Our research has shown that CAC scores are a reliable indicator of heart health for both men and women. This is particularly significant because, traditionally, heart disease has been viewed through a male lens. Our findings indicate that women, often diagnosed at a later stage, can also benefit from this predictive tool. A zero CAC score, indicating no calcified plaque, can signal a low risk for heart complications and all-cause mortality.
**Editor:** That’s fascinating! You mentioned that women often present with heart disease later in life. How did your findings reflect this pattern?
**Dr. Anderson:** Yes, we observed that the average age of women in our study was 60.5 years compared to 53.8 years for men. Despite being older, women were more likely to achieve a zero CAC score, which suggests they might have healthier arteries at that age. This finding highlights the importance of advocating for heart health assessments in women earlier on.
**Editor:** The non-invasive nature of CAC testing seems to be a huge draw for patients. How does this compare to more invasive heart health assessments?
**Dr. Anderson:** CAC testing is indeed non-invasive and carries minimal radiation exposure similar to that of a mammogram. It serves as an affordable alternative to more invasive procedures such as coronary angiography or PET stress tests. This accessibility is key in promoting proactive heart health screenings.
**Editor:** You mentioned exploring further implications of a zero CAC score. What direction do you plan to take with this research?
**Dr. Anderson:** We’re committed to understanding why a zero CAC score correlates so strongly with overall health outcomes. This could have broader implications for preventive care in cardiovascular health and beyond. We hope to delve deeper into the underlying mechanisms and perhaps guide future clinical practices.
**Editor:** Dr. Anderson, thank you for sharing these insights! It’s clear that CAC scores hold valuable information for both heart health and broader health outcomes. We look forward to hearing more from you as this research progresses.
**Dr. Anderson:** Thank you! It’s been a pleasure discussing our findings, and I’m excited about the potential for improving patient care through this research.
