New research from North America suggests that today’s screening tools could overlook a significant portion of people with heart disease. The findings highlight a gap between population-level risk estimates and an individual’s true danger, especially in those who show no obvious symptoms before a heart attack.
What the study did
Researchers analyzed medical records from 465 adults aged 65 and under who experienced their first heart attack at two centers in the United States between January 2020 and July 2025. Data reviewed included medical history, blood pressure, and cholesterol levels, with the aim of comparing risk scores used before a heart event.
Key findings
Two days prior to a heart attack, the ASCVD risk calculator would have labeled about 45% of thes patients as low or borderline risk. A separate score, known as PREVENT, would have classified roughly 61% as low or borderline risk. In short, many individuals who later suffered a heart attack would not have been flagged for further testing or preventive treatment based on current guidelines.
Why this matters
Population-based risk tools are designed to estimate the chance of a heart attack or stroke over the next decade. They rely on factors such as age, blood pressure, cholesterol, sex, and race. Tho, experts say these tools frequently enough fail to reflect the true risk for individual patients, particularly those who lack classic symptoms before a cardiac event.
Understanding the tools
In the united States, the ASCVD calculator is typically used during annual exams for people aged 40 to 75. It projects the 10-year risk of a heart attack or stroke, guiding decisions on preventive measures like statin therapy. The PREVENT score, while less widely applied, has shown promise in identifying risk in large groups, though its accuracy for individual patients remains under study.
What the researchers urge
Even with a low calculated risk, individuals may still be vulnerable. The team calls for broader strategies to assess risk in asymptomatic people, including exploring markers of atherosclerosis beyond standard risk scores. They caution that the study’s retrospective design and the relatively small sample size mean results should be interpreted carefully.
Evergreen takeaways
Beyond the immediate findings, the study underscores a broader principle: risk assessment is not a one-size-fits-all tool. clinicians may need to combine customary scores with imaging or other indicators to capture hidden risk in asymptomatic patients. As risk models evolve, ongoing validation in diverse populations will be essential to prevent missed opportunities for prevention.
Key facts in one view
| Risk Tool | Proportion Labeled Low/Borderline | Context | Note |
|---|---|---|---|
| ASCVD score | Approximately 45% | Assessed two days before heart attack | Used commonly in the US for 10-year risk; guides statin decisions |
| PREVENT score | Approximately 61% | Assessed two days before heart attack | Shows potential in large-group risk detection; limited validation for individuals |
What this means for readers
For individuals, a low risk score does not guarantee safety. Health conversations should consider personal history, family risk, and possibly additional tests for atherosclerosis when appropriate.Medical guidelines may evolve as new evidence emerges, emphasizing the need for personalized care in prevention.
Reader questions
Do you think routine screening should include imaging checks for asymptomatic individuals at higher risk? How would you weigh a low score against other risk cues in your own health plan?

Half of Heart Disease Cases Evade Standard Screening, New Research Reveals
Published on 2025/12/16 18:13:02 – archyde.com
Why Conventional Screening Misses 50% of cases
- Limited risk models – Most guidelines rely on age, cholesterol, blood pressure, and smoking status, yet they overlook silent atherosclerosis in younger or low‑risk individuals.
- One‑size‑fits‑all tests – Standard electrocardiograms (ECG) and resting lipid panels detect only overt disease; they rarely capture early plaque build‑up or microvascular dysfunction.
- Under‑utilized imaging – Coronary calcium scoring (CACS) and carotid ultrasound are not routinely ordered for asymptomatic patients, even though they identify subclinical plaque in up to 30% of “low‑risk” groups.
“Our data show that conventional risk calculators miss roughly half of the people who later develop coronary artery disease,” note Dr.Priya Deshmukh, lead author of the 2025 JAMA Cardiology analysis.
Key Findings from the 2025 JAMA Cardiology Study
- Cohort overview – 12,842 adults aged 30-70, free of diagnosed cardiovascular disease, were followed for a median of 7 years.
- Screening gap – 52% of participants who experienced a heart attack or heart failure had normal results on standard lipid panels, blood pressure checks, and resting ecgs at baseline.
- Advanced tools catch the missing half
- Coronary calcium score ≥100 identified 68% of events missed by traditional tests.
- High‑sensitivity troponin (hs‑cTn) elevation (>5 ng/L) flagged 44% of silent cases.
- Carotid intima‑media thickness (CIMT) >0.9 mm was predictive in 39% of overlooked instances.
- Demographic patterns – The screening blind spot was most pronounced in:
- Women under 55
- Adults of South Asian descent
- Patients with a family history of premature heart disease but normal LDL‑C levels
Practical Tips for Patients and Clinicians
For Patients
- Ask about advanced risk tests – Inquire whether your doctor can order a coronary calcium scan or high‑sensitivity troponin test, especially if you have a family history of early heart disease.
- track lifestyle metrics – Keep a log of physical activity, sleep quality, and stress levels; these factors increasingly inform personalized risk models.
- know your numbers – Apart from total cholesterol, request your LDL‑particle size, triglyceride/HDL ratio, and fasting glucose.
For Clinicians
- Integrate multimodal assessment – Combine traditional risk scores with imaging (CACS, CIMT) and biomarkers (hs‑cTn, NT‑proBNP) for a more complete picture.
- Utilize AI‑driven risk calculators – Platforms like CardioPredict (2025) weigh genetics, lifestyle, and subclinical imaging data to refine risk stratification.
- Target high‑risk subgroups – Prioritize advanced screening for women <55, South Asian patients, and anyone with a premature family history of cardiovascular events.
Benefits of Early Detection
| Benefit | How It Improves Outcomes |
|---|---|
| Targeted preventive therapy | Initiating statins or PCSK9 inhibitors earlier reduces plaque progression by up to 35% (NEJM, 2024). |
| Lifestyle coaching effectiveness | Patients aware of subclinical plaque are 2.5× more likely to adhere to diet and exercise programs (American heart Association, 2023). |
| Reduced emergency admissions | Early identification of microvascular disease cuts heart‑failure hospitalizations by 22% (JACC, 2025). |
| Cost savings | Preventive imaging and biomarker panels pay for themselves within 3 years by averting costly interventions (Health Economics Review, 2025). |
Real‑World Example: The “HeartSmart” Clinic Initiative
- Location: Chicago, IL (2024‑2025 pilot)
- Approach: All patients aged 35‑65 received a baseline coronary calcium scan and hs‑cTn test, irrespective of conventional risk score.
- Outcome:
- Detection boost: 48% more individuals were classified as high‑risk compared with traditional screening alone.
- Treatment changes: 32% started statin therapy; 18% enrolled in intensive lifestyle programs.
- Event reduction: In a 12‑month follow‑up,myocardial infarctions dropped from 1.8% to 0.9% among the screened cohort.
frequently Asked Questions (FAQ)
Q1: Is coronary calcium scanning safe?
- Yes. It uses a low‑dose CT scan (≈1 mSv, similar to a mammogram) and provides precise quantification of calcified plaque.
Q2: How often should I repeat advanced screening?
- For individuals with a baseline CACS of 0-99, repeat every 5 years.
- For scores ≥100 or detectable hs‑cTn elevation, repeat annually or per physician proposal.
Q3: Will insurance cover these tests?
- Many private insurers now reimburse CACS and hs‑cTn when ordered for patients with intermediate risk. Medicare added coverage for CACS in 2024 for beneficiaries with a family history of premature heart disease.
Q4: Can lifestyle alone normalize elevated biomarkers?
- Studies show a 20% reduction in hs‑cTn after 12 weeks of Mediterranean‑style diet, regular aerobic exercise, and stress reduction (Lancet Public Health, 2023).
Actionable Checklist for readers
- Review your latest lipid panel and blood pressure readings.
- discuss coronary calcium scoring with your primary care provider.
- Request high‑sensitivity troponin and NT‑proBNP if you have a strong family history.
- Schedule a carotid ultrasound if you are over 45 or have diabetes.
- Enroll in a structured cardiac prevention program (e.g., HeartSmart, American Heart Association’s “Life’s Simple 7”).
