Science Magazine – March 31, 2023 issue: A new analysis shows that Great Plains tribes acquired horses much earlier than some historians had thought, consistent with Indigenous descriptions of a long and enduring partnership with the horse. This petroglyph, from the Tolar site in southern Wyoming, probably dates from soon after the modern horse became widespread in North America in the early 17th century.

Straight from the heart: Mysterious lipids may predict cardiac problems better than cholesterol

Conceptual illustration: a giant heart opens up on a hinge to reveal several gauges. Three of them, labeled HDL, LDL, and ApoB, display low levels. One, labeled Ceramides, displays high levels and is vibrating and letting off steam. Three tiny scientists stand at the foot of the heart, and one shines a flashlight on the Ceramides gauge.

Drug developers are now trying to target ceramides, which appear to contribute to a range of metabolic disorders

Health: How ‘Statins’ Prevent Heart Attacks And Strokes’ (CDC Video)

Statins are a type of medication used to lower the level of bad cholesterol in the blood and reduce build-up in arteries that can cause a heart attack or stroke. This short animated video explains the importance of statins, how they work, and why your doctor may prescribe them.

Heart Health: “Statins” Are Beneficial Only With Healthy Diets & Lifestyle

Taking a statin helps keep your cholesterol levels in check. How can that be?

Mayo Clinic LogoDr. Stephen Kopecky explains that some people ask to be put on a statin. That’s because statins, while important and effective, are just one part of the whole heart-healthy picture. When you combine a statin with regular exercise, maintaining a healthy weight, controlling stress, not smoking and eating foods based on the Mediterranean diet, you can improve your heart health.

Dr. Kopecky says if you work in lifestyle changes slowly over time, you’ll be on your way to better heart health.

Statins are drugs that can lower your cholesterol. They work by blocking a substance your body needs to make cholesterol. Statins may also help your body reabsorb cholesterol that has built up in plaques on your artery walls, preventing further blockage in your blood vessels and heart attacks.

Several statins are available for use in the United States. They include:

  • atorvastatin (Lipitor)
  • lovastatin (Altoprev)
  • pitavastatin (Livalo)
  • pravastatin (Pravachol)
  • rosuvastatin (Crestor)
  • simvastatin (Zocor)

Sometimes, a statin is combined with another heart health medication. Examples are atorvastatin/amlodipine (Caduet) and simvastatin/ezetimibe (Vytorin).

Increasing evidence suggests that statins do more than just lower bad cholesterol. Research has found that the medicines can safely prevent heart disease in certain adults ages 40 to 75. But the benefits aren’t entirely clear for the elderly. And doctors still want to know more about the side effects of statins.

Boomers Health: Fasting Before Blood Tests For Cholesterol Is Not Necessary Study Finds

From a Harvard Heart Health online article:

Non Fasting Blood Testing for ChloresterolFor the study, nearly 8,300 people at risk for heart disease had fasting and nonfasting lipid profile tests done at least four weeks apart. (Fasting means they had nothing to eat or drink except water for at least eight hours before the test.) The differences in their total, LDL, and HDL cholesterol values were negligible. Triglyceride levels were modestly higher in the nonfasting samples.

Don’t want to skip breakfast before your cholesterol test? You probably don’t need to. A study published online May 28 by JAMA Internal Medicine adds to the evidence that fasting isn’t necessary before this common blood test, often referred to as a lipid profile.
