Health Studies: Women’s Blood Vessels Age Faster Than Men’s, Increasing Heart Disease Risks

From a Cedars-Sinai.org online release:

Cedars Sinai logo“Our data showed that rates of accelerating blood pressure elevation were significantly higher in women than men, starting earlier in life,” said Cheng, the Erika J. Glazer Chair in Women’s Cardiovascular Health, who also serves as director of Cardiovascular Population Sciences at the Barbra Streisand Women’s Heart Center. “This means that if we define the hypertension threshold the exact same way, a 30-year old woman with high blood pressure is probably at higher risk for cardiovascular disease than a man with high blood pressure at the same age.”

Women's Blood Vessels Age Faster Than Men;s Cedars-Sinai January 15 2020

(January 15, 2020) – New research from the Smidt Heart Institute at Cedars-Sinai showed for the first time that women’s blood vessels – including both large and small arteries – age at a faster rate than men’s. The findings, published Wednesday in the journal JAMA Cardiology, could help to explain why women tend to develop different types of cardiovascular disease and with different timing than men.

Top New Travel Videos: “Wild Iceland” From Eaglewood Pictures

Filmed and Directed by: Arvīds Barānovs

In 2019 I led two expeditions into the wild Iceland. We skipped the most touristy spots you have probably seen a million times on Instagram and went deep into the Highlands and around the remote Westfjords including a long multi-day hike in Hornstrandir to find the real taste of this beautiful land.

In summer 2020 I will be returning with another Westfjords expedition and you’re welcome to join our small group: facebook.com/events/427469747931313/

History Of Food: “How The New York City Bagel Was Born” (NYU Video)

Bagels have roots in 17th-century Poland, but it’s American wheat—along with Jewish immigration to New York, labor organizing, and an epic battle between bakers—that made them what they are today. Jacob Remes, a clinical associate professor at NYU’s Gallatin School who has studied this history, says nobody has had a real New York bagel since 1967.
