High Hormone Levels Put Young Black Males at Risk for Cardiovascular Disease

Medical News Today, December 12, 2012

Increased levels of the hormone c in young black males correlate with an unhealthy chain of events that starts with retaining too much salt and results in an enlarged heart muscle, researchers say.

The findings indicate physicians may want to reach for aldosterone inhibitors early in their effort to control blood pressure and reduce cardiovascular risk in young black males.

Their studies of a cohort of 191 healthy black and white 15- to 19-year-olds showed that only in the black males was higher aldosterone associated with impaired sodium excretion, increased blood pressure and enlargement of the left pumping chamber of the heart, said Dr. Gregory A. Harshfield, hypertension researcher at the Medical College of Georgia and Institute of Public and Preventive Health at Georgia Health Sciences University.

“It’s a clear pathway and is consistent with the idea that is the highest risk group for developing earlier and more severe cases of hypertension,” Harshfield said. {snip} Harshfield’s studies have shown that black males particularly have a problem with blood pressure returning to normal following stress because of an impaired ability to eliminate sodium.

The steroid hormone aldosterone, produced by the adrenal gland, is part of a renin-angiotensin-aldosterone system that helps the body regulate blood pressure and sodium retention. Aldosterone acts on the kidneys, prompting them to hold onto sodium which increases blood pressure. While that can be an asset in some finite scenarios, such as having limited access to water over an extended period, it can become a major health liability in the everyday world where you can consume a day’s sodium requirement in single pack of crackers, Murro said.

Interestingly, only 16 of the study participants were obese, and there was no significant correlation between obesity—a major contributor to hypertension and heart disease—and higher aldosterone.

Similar studies are needed in hypertensive youth or those with a family history of high blood pressure to see if their findings hold, the researchers said. One of the newer, more selective aldosterone blockers, eplerenone, has proven more effective than the angiotensin II receptor blocker losartan at treating hypertension in a predominantly black, adult male population. While angiotensin is a precursor for aldosterone, at least one study indicates it’s not very effective at directly suppressing aldosterone.

    But…but…I thought race was a social construct.

    • MekongDelta69

      Built by black (social) construction workers, so obviously, it immediately collapsed.

      Liberals will claim that the racism young black men encounter causes their aldysterone stuff to get over produced.

      • MikeofAges

        Hormones are inducible, but I don’t think that’s much of an explanation. But liberals are not big on the plausibility of their explanations. I have it on good authority than climate change is caused by people in the stratosphere. But the liberals don’t want ground the jet set, so they propose to make us live in the dark and cold. Not pie in the sky. Jet trails form a thin stratospheric cloud layer which decreases the temperature differential between night and day. Though there may not be actual warming, the total amount of time the temperature is below freezing is reduced and this leads to increased melting of glaciers and the polar ice packs, or so the theory proposes.

        A long-time friend of mine, when I explain these things to him, always says, “Not to make too find a point, but that’s why we need nuclear war.” Of course, he’s just a disaffected old vet with two major diseases, and who knows how long to go.. Pay him no mind when he says, “Let’s throw everything up in the air and see how it comes down.”

      Or, perhaps the great anthropologist Franz Boas, himself a member of a minority, wasn’t exactly telling the truth, after all? Now, you must believe me when I say, I am in no way suggesting that he (who by the way had no knowledge about genetics) might have had some kind of agenda, but……

  • Oil Can Harry

    This article is a total lie. Race is a social construct; there are no genetic racial differences.

    The real reason blacks have a higher risk of heart disease is because they suffer from institutionalized racism, white privilege, stereotype threat, racial profiling and stress caused by the legacies of slavery and Jim Crow.

    • Nicholai Hel

      Aldosterone is a white sodium privilege hormone. Is there a mandatory diversity class aldosterone can attend to make it less sodium loving and more tolerant of melanin?

    • MikeofAges

      Increase potassium intake. And less sodium-loaded ingestibles like chips and fermented malt beverages. I suggest orange juice, apple juice and bananas. And don’t get testy about the bananas. I eat them daily myself and they do help my blood pressure a little.

      • David Ashton

        It is racist to offer a black person a banana (on the football field anyhow).

      • mobilebay

        Bananas are also a great source of potassium.

      Wrong on all counts people, It’s a well known fact in the black community that the CIA has aircraft fitted out to dispense sodium over black cities.

    • OlderWoman

      More excuses. How bor-r-r-ing.

    • Joseph

      I read (in Ebony) that it is because the CIA puts chemicals into Colt45 that causes heart-attacks in people with much melanin.

      • OlderWoman

        It could be all the stress from opening and downing the contents out of a 40 ouncer.

    • haroldcrews

      You’ll only find DWL’s who possess the minimal integrity of intellectual consistency denying racial differences in favor of race as a social construct on all occasions. This is as you would imagine a very small number. The overwhelming majority of them live with Orwell’s doublethink and doublespeak. They are firmly rooted in the totalitarian mindset. Freedom is saying that 2+2=4 but let us not forget that 100 > 85.

  • You Are Now Enriched

    This story is one big made up hate lie hoax. It’s not true, because there is no such thing as race, only the Human Race, and we are all one family. I feel no differently when I see a picture of George Washington than when I see Al Sharpton.

    • BellaCosa

      Also, we’re all winners. You forgot that part.

      • Jeff

        Oh yeah, that’s right. We’re all winners. High taxes and entitlements benefit everyone. Everyone wins with diversity. Wealth redistribution is a win-win for everyone. Mass third world immigration benefits everyone also.

        Thanks for reminding me, I almost forgot all that!

    • Francois

      And I really feel like I am looking at myself in a mirror, when I see Eddie Murphy on television.

  • C_C_Conrad

    Oh I’ve known that for a long time. That’s why I have been giving blacks blankets with salt sprinkled on them for years.

    • IstvanIN

      You would be more successful with salted pork and collards.

  • JohnEngelman

    Evolving in a hot climate, the Negro body developed the ability to retain salt. That makes blacks more vulnerable to the high salt diet at fast food restaurants.

    • MikeofAges

      How could you begin to imagine that the environments the various ancestors of modern people survived in for 2,000 generations could possibly have any effect on their characteristics today? Double plus ungood, buddy.

      • François

        Yes, absolutely! The anthropologist Franz Boas wrote that race was purely a social construct! And that whole thing about the skin of Blacks having more melanin… I mean, any dermatologist will tell you it is the case, only for aesthetic reasons, and that that has nothing to do with exposure to the sun’s rays. Damn, those evil White supremacists are so intellectualy dishonest!!!

  • Sherman_McCoy

    Would castration help? I mean, it couldn’t hurt, right? It’s worth a try.

  • Bill

    If true, we can only hope the deleterious effects accelerate in conclusive final pathology. Kind of like the common flue germ killed off all the aliens in War of the Worlds.

  • http://www.facebook.com/willard.gage.3 Willard Gage

    could “energy drinks” which cause the adrenal gland to pump out adrenalin and also insulin also cause the adrenal glands of black males to pump out more aldosterone?

    • OlderWoman

      I don’t know. And I don’t want to look to see if it does.

  • http://www.facebook.com/willard.gage.3 Willard Gage

    OK, so the salt be rayciss but whuddabout da peppah?

    • Angry White Woman

      Of course de peppah don’t be rayciss, it be black! De Brotha Eric Holder his’self done say so.

    Several years ago, a soft drink called Tropical Fantasy showed up in NYC suprettes. Rumors claimed that it was designed to sterilize black males. So I don’t believe this story either.

    • Joseph

      ‘Twas yet another tropical fantasy.

    • Johnny Clay

      I heard a similar story that the Church’s Fried Chicken chain was owned by the KKK and that the food contained chemicals that sterilized black men.

      • Michael_C_Scott

        I’ve heard plenty of these rumors over the last 20 years, and I always have to ask myself, why don’t any of these “sterilize the black males” chemical additives seem to be working? Chemical castration isn’t exactly new technology, after all.

    • Pelayo

      Where can I buy stock in the bottling company?

  • Jefferson

    White America should care that Black men are getting cardiovascular disease because ? As a White person, am I suppose to lose sleep over this ?

    • IstvanIN

      I thought the same thing but felt it might be too tacky to say “who cares?”

      • OlderWoman

        Hahahaha.

  • Pelayo

    The person that I used to be would never say this but the circumstances of the last few decades have certainly changed my world view. A this point anything that puts “young Black males” at risk is fine with me. They been putting us at risk for the last 60 years. it’s time for paybacks. All you ” youths” out there! Load up on that salt; at least five tablespoons full per diem. Nome sane? Eat lots of Chips too. Dey be goot fo y’all.

    • Michael_C_Scott

      I’m afraid sodium intake doesn’t really matter where dem youfs are concerned. How many of them are really going to live long enough to have heart-attacks anyway?

  • Jeff

    Well, we all knew their high testosterone levels put them at risk for lead poisoning, and now we find out sodium is a problem as well.

    Maybe someone will finally discover why white parents don’t want their white daughters in schools with black “boys”?

  • http://popeyes.com/ Harland_Sanderz

    I read the headline and asked myself “So what’s the problem?”
