High blood levels of lipoprotein(a), or Lp(a) — a variant of LDL cholesterol — may triple the risk of a heart attack, even among people with no other risks for heart disease, a new study confirms.
The study included 6,238 people ages 43 to 65 who had their Lp(a) levels measured. Values in the top 10% — 216 nanomoles per liter (nmol/L) or greater — were defined as high, while values in the lower 50% — less than 42 nmol/L — were defined as low.

Concerns about the health effects of microplastics continue to mount. Now, a new study finds that people with microplastics in the plaque clogging their neck arteries were far more likely to have a heart attack or stroke than people with plastic-free plaque.
When researchers tested the plaque removed from the neck arteries of 257 people, they found tiny particles of plastic — mostly polyethylene but also polyvinyl chloride — in 58% of the people.

The ketogenic (keto) diet — which is high in fat and protein and low in carbohydrates — doesn't meet standards for a healthy diet and may not be safe for some people with heart disease, according to a review in the March 2024 issue of Current Problems in Cardiology. The review summarized the current evidence on how keto diets may raise heart disease risk. While the diet may dramatically reduce fat mass and weight over the short term, there is scarce evidence for any long-term benefit.
