Vital Years Weekly #2: Your Heart After 55 — What the Latest Research Says
Cholesterol has dominated the conversation for 40 years. But a newer marker is proving to be a far stronger predictor of heart attack risk — especially after 55.

Dear Health-Conscious Friends 55+,
Heart disease is still the leading cause of death for adults over 55 in the United States. But the way cardiologists think about risk has changed significantly in the past decade — and most of that shift hasn't reached the general public yet.
This week: the number that matters more than total cholesterol, and what you can do about it starting today.
Why Cholesterol Alone Misleads You
Half of all heart attack patients have normal LDL cholesterol. That single statistic should tell you something important: total cholesterol, and even LDL cholesterol in isolation, are incomplete tools.
What cardiologists now pay close attention to is inflammation — specifically a marker called high-sensitivity C-reactive protein (hs-CRP). A landmark paper in the New England Journal of Medicine (the JUPITER trial, 2008) showed that people with elevated hs-CRP but normal LDL had significantly elevated heart attack risk — and that treating the inflammation reduced events substantially.
Three Insights From This Week
1. Your hs-CRP Number Is as Important as Your LDL
hs-CRP below 1 mg/L is low risk. Between 1–3 mg/L is moderate. Above 3 mg/L is high risk. Many adults over 55 have never had this test. Ask your doctor to include it in your next bloodwork panel — it's inexpensive and covered by most insurance.
2. The Coronary Calcium Score Is the Best Screening Tool You've Probably Never Had
A coronary artery calcium (CAC) scan is a low-dose CT scan that measures calcified plaque in your arteries — actual physical evidence of disease, not just a risk estimate. A score of zero means very low 10-year event risk. A score above 400 means significant disease is already present. The scan costs roughly $100–150 out of pocket and takes about 10 minutes. For adults 55–70 with any cardiac risk factors, it's arguably the most actionable screening tool available.
3. Blood Pressure at Night Matters More Than During the Day
A 2019 study in the European Heart Journal found that nighttime blood pressure was a stronger predictor of cardiovascular events than daytime readings. "Non-dippers" — people whose blood pressure doesn't fall during sleep — have significantly elevated risk. If you have hypertension, ask about 24-hour ambulatory blood pressure monitoring rather than relying on office readings alone.
What Actually Lowers Cardiac Risk After 55
The most evidence-backed interventions are less glamorous than the supplements advertised on health podcasts: consistent aerobic exercise (which reduces hs-CRP by 30–40% on its own), a Mediterranean diet pattern, maintaining healthy blood pressure, not smoking, and — if prescribed — appropriate medications including statins, blood pressure drugs, and low-dose aspirin (though aspirin recommendations have shifted; discuss with your doctor).
Zone 2 cardio — exercise where you can hold a conversation but are breathing harder than normal — is particularly powerful. Aim for 150+ minutes per week.
This Week's Action Step
Pull out your most recent bloodwork. Check whether hs-CRP was included. If not, add it to your list of questions for your next doctor visit. Also check your most recent blood pressure reading — and if it was taken only at the doctor's office, consider a home monitor (they're inexpensive and far more informative).
Next week: one of the most underappreciated drivers of disease after 55 — chronic low-grade inflammation — and the three dietary changes with the strongest evidence for reducing it.
