Statins have become the “gold standard”
for the treatment of high cholesterol—and
a new type of drug known as PCSK9
inhibitors could make them even better. In
a recent study, researchers split a group of
968 volunteers into two groups: one taking
only a statin, the other combining the
drug with evolocumab, a PCSK9 inhibitor.
After 18 months, the team measured
the participants’ levels of LDL, or “bad
cholesterol.” Anything below 100 milligrams
per deciliter of blood is considered
excellent, and those who were taking only
a statin averaged an impressive 93 mg/dL.
But those taking a combination of the two
drugs averaged an astonishing 36 mg/dL
of LDL—an ultralow level generally seen
only in babies. “In a sense,” says cardiologist
Elliott Antman, who wasn’t associated
with the study, “you are turning back
the cardiovascular clock.” These striking
reductions came with an added benefit,
reports Reuters.com: greater declines in
dangerous plaques that had accumulated
in the patients’ arteries. Plaques shrank in
two-thirds of those taking both drugs, but
in only half of those taking a statin alone.
The only downside of PCSK9 inhibitors is
their cost: With some prescriptions priced
at $14,000 a year, most insurers are refusing
to pay for them.
La Niña’s impact on weather
Months after the conclusion of one of the
strongest El Niños in history, the weather
system’s lesser-known sister, La Niña, has
finally made her arrival. Unlike El Niño,
which occurs when ocean temperatures
in the Pacific become unusually warm,
La Niña cools the surface of the tropical
Pacific, altering the storm track over North
America and other parts of the world.
El Niño was blamed for last year’s balmy
winter in the Northeast and soaking rains
in the drought-stricken West; La Niña will
have the opposite effect, ushering in wetter,
cooler conditions in the northern states
and exacerbating dry conditions across
the South. The weather system “is likely
to contribute to persisting or developing
drought across much of the southern U.S.
this winter,” Mike Halpert of the National
Oceanic and Atmospheric Association, tells
CNN.com. An ongoing drought in Southern
California also is likely to continue. This
La Niña isn’t particularly strong, and is
expected to last only until spring.
