Almost no one over 50 has normal blood pressure now.

Leave a reply

Four years ago, when the average lifespan of American men was 3.1 years longer than today, the American Heart Association and the American College of Cardiology dropped the standard for normal- acceptable blood pressure for 50+ years olds from 140/90 to 120/80. The new standard of normal was for everyone regardless or age or gender despite the fact that virtually no one over 50 now reached it. Normal is now quite un-common.

By the new definition, virtually everyone over 50 now is diagnosed with high blood pressure or hypertension. Almost all require one or two medications — no more baby aspirin. Though the evidence for aspirin’s benefit is strong, it doesn’t lower blood pressure. AHA guidance is to lower a patients blood pressure to <140/90 mmHg or at least treat him/her with 2–3 antihypertensive medications.4 

Average systolic blood pressures for long-lived populations of men and women without drugs.

The graphs shows the average blood pressures, without drugs in a 2008 study of the longest-lived, Scandinavian populations. These were the source of the previous targets: the natural pressures for the healthiest populations at the time, based on the study of 1304 men (50-79 years old) and 1246 women (38-79 years old) observed for up to 12 years. In this healthy population, the average untreated systolic pressure is seen till age 70, reaching 154 for men, and over 160 for women. By the new standards, these individuals would be considered highly unhealthy, though they live a lot longer than we do. The most common blood-pressure drug prescribed in the US today is atenolol, a beta blocker. See my essay on Atenolol. It’s good at lowering blood pressure, but does not decrease mortality.

The plot at left shows the relationship between systolic blood pressure and death. There is a relationship, but it is not clear that the one is the cause of the other, especially for individuals with systolic pressure below 160. Those with pressures of 170 and above have significantly higher mortality, and perhaps should take atenolol, but even here it might be that high cholesterol, or something else, is causing both the high blood pressure and the elevated death risk.

The death-risk difference between 160 and 100 mmHg is small and likely insignificant. The minimum at 110 is rather suspect too. I suspect it’s an artifact of a plot that ignores age. Only young people have this low number, and young people have fewer heart attacks. Artificially lowering a person’s blood pressure, even to this level does not make him young, [2][3] and brings some problems. Among the older-old, 85 and above, a systolic blood pressure of 180 mmHg is associated with resilience to physical and cognitive decline, though it is also associated with higher death rate.

The AHA used a smoothed version of the life risk graph above to justify their new standards, see below. In this version, any blood pressure looks like it’s bad. The ideal systolic pressure seems to be 100 or below. This is vastly too low a target, especially for a 60 year old. Based on the original graph, I would think that anything below 155 is OK.

Light exercise seems to do some good especially for the overweight. Walking helps, as does biking, and aerobics. Weight loss without exercise seems to hurt health. Aspirin is known to do some good, with minimal cost and side effects. Ablation seems to help for those with atrial fibrillation. Elequis (a common blood thinner) seems to have value too, for those with atrial fibrillation — not necessarily for those without. Low sodium helps some, and coffee, reducing gout, dementia and Parkinson’s, and alcohol. Some 2-3 drinks per day (red wine?) is found to improve heart health.

I suspect that the Scandinavians live longer because they drink mildly, exercise mildly, have good healthcare (but not too good), and have a low crime rate. They seem to have dodged the COVID problem too, even Sweden that did next to nothing. it’s postulated that the problem is over medication, including heart medication.

Robert Buxbaum, January 4, 2023. The low US lifespan is startling. Despite spending more than any other developed countries on heath treatments, we have horribly lower lifespans, and it’s falling fast. A black man in the US has the same expected lifespan as in Rwanda. Causes include heart attacks and strokes, accidents, suicide, drugs, and disease. Opioids too, especially since the COVID lockdowns.

Eliquis, over-prescribed but better than Coumadin.

Eliquis (apixaban) is blood thinner shown to prevent stroke with fewer side effects than Warfarin (Coumadin). Aspirin does the same, but not as effectively for people over 75. My problem with eliquis is that it’s over-prescribed. The studies favoring it over aspirin found benefits for those over 75, and for those with A-Fib. And even in this cohort the advantage over aspirin is small or non-existent because eliquis has far more serious side effects; hemorrhage, or internal bleeding.

Statistically, the AVERROES study (Apixaban Versus Acetylsalicylic Acid to Prevent Stroke in AF Patients Who Have Failed or Are Unsuitable for Vitamin K Antagonist Treatment) found that apixaban is substantially better than aspirin at preventing stroke in atrial fibrillation patients, but worse at preventing heart attack.

Taking 50 mg of Eliquis twice a day, reduces the risk of stroke in people with A-Fib by more than 50% and reduces the rate of heart attack by about 15%. By comparison, taking 1/2 tablet of aspirin, 178 mg, reduces the risk of stroke by 17% and of heart attack by 42%. The benefits were higher in the elderly, those over 75, and non existent in those with A-Fib under 75, see here, and figure. Despite this, doctors prescribe Eliquis over aspirin, even to those without A-Fib and those under 75. I suspect the reason is advertising by the drug companies, as I’ve claimed earlier with Atenolol.

The major deadly side-effect is hemorrhage, brain hemorrhage and GI (stomach) hemorrhage. Here apixaban is far worse than with aspirin (but better than Warfarin). The net result is that in the AVERROES random-double blind study there was no difference in all-cause mortality between apixaban and aspirin for those with A-fib who were under 75, see here. Or here.

To reduce your chance of GI hemorrhage with Eliquis, it is a very good idea to take a stomach proton pump drug like Pantoprazole. If you have A-Fib, the combination of Eliquis and pantoprazole seems better than aspirin alone, even for those under 75. If you have no A-Fib and are under 75, I see no benefit to Eliquis, especially if you find you have headaches, stomach aches, back pain, or other signs of internal bleeding, you might switch to aspirin or choose a reduced dose.

A Japanese study found that half the normal dose of Eliquis, was approximately as effective as the full dose, 50 mg twice a day. I was prescribed Eliquis, full dose twice a day, but I’m under 70 and I have no A-Fib since my ablation.

Life expectancy has dropped in the US to undeveloped world levels. Biden blames COVID and racism. I think it’s too much drugs, and too few opportunities.

I’m struck by the fact that US life expectancy is uncommonly low, lower than in most developed countries. Lower too than in many semi-developed countries, and our life expectancy is decreasing while other countries are not seeing the same. It dropped by about 3 years over the last 2 years as shown. I wonder why the US has suffered more than other countries, and suspect we are over-prescribed. Too much of a good thing, typically isn’t good.

COVID is 1/50 as deadly in China, Hong Kong, Taiwan, Korea…

I may be paranoid, but that doesn’t mean I’m crazy. COVID-19 shows a remarkably low death rate in Asia, particularly Eastern Asia, compared to the US or Europe or South America. As of this month, there have been 734,600 US deaths from COVID-19, representing 0.22% of all Americans. Another way of stating this is 2.2 deaths per thousand population. In one year, COVID has lowered the life expectancy of US men by 2.1 years; with the decline worst among hispanic men. The COVID death rate is very similar in Europe, and higher in South America (in Peru 0.62%), but hardly any deaths in East Asia. In China only 4,636 people, 0.003% of the population. That’s 1/700th the rate in the US, and almost all of these deaths are in western China. They no longer bother with social distancing.

The low death rate in East Asia. was noted by the BBC over a year ago. Based on today’s data from Worldometer, here, the low death rates continue throughout East Asia, as graphed at right. In Hong-Kong the death rate is 0.03 per thousand, or 1/70th the US rate. In Taiwan, 0.04 per thousand; in Singapore, 0.01 per thousand; in S. Korea 0.04 per thousand; Cambodia and Japan, 0.1 per thousand. The highest of these countries shows 1/20 the death rate of the US. This disease kills far fewer East Asians than Westerners. This difference shows up, for example in a drop in the lifespan of male Americans by 2.16 years. The lifespan of male Hispanics dropped more, by 4.58 years. In China, Japan, and Korea the lifespans have continued to increase.

Life expectancy for US males has dropped by 2.16 years. It’s dropped more for Hispanic and Black Americans. Data for women is similar but not as dramatic.

My suspicion is that this was a racially targeted bio-weapon. But perhaps the targeting of westerners reflects a cultural lifestyle difference. Mask use has been suggested, but I don’t think so. In many high mask countries the death rate is high, while in low mask Taiwan and Korea it’s low, only 0.04 COVID deaths per thousand. Even Sweden, with no masks reports only 1.4 per thousand deaths; that’s 2/3 the death rate of the US. Masks do not seem to explain the difference.

Another lifestyle difference is obesity; Americans are fat. Then again, Peru was hit far worse than we were, and Peruvians are thin. Meanwhile, in Hong Kong, folks are fat, but the death rate is small. Another cultural difference is medicine, but I don’t believe Sweden, Germany, and France have worse healthcare than Taiwan or Cambodia. Cambodia saw 1/20 the US COVID death rate.

My suspicion is that this disease targets by race because it was designed that way. If it isn’t a bio weapon, it certainly behaves like one. I may be paranoid here, but that’s the way it seems.

As a side issue, perhaps related, I note that China keeps pushing for the to close its manufacturing in the interest of CO2 abatement, while they keep building coal burning power plants to fill the manufacturing need that we abandon. I also notice that they hit us with tariffs while protesting our tariffs, that they steal our intellectual property, and that they are building islands in the sea between China and Japan. There is war-tension between our countries, and Western-targetting virus appears right outside of China’s top-security virus lab — their only level 4 lab — I’m guessing it’s not a total coincidence.

The Japanese diet, a recipe for stomach cancer.

3 Replies

Japan has the highest life expectancy in the world, an average about 84.1 years, compared to 78.6 years for the US. That difference is used to suggest that the Japanese diet must be far healthier than the American. We should all drink green tea and eat such: rice with seaweed and raw or smoked fish. Let me begin by saying that correlation does not imply causation, and go further to say that, to the extent that correlation suggests causation, the Japanese diet seems worse. It seems to me that the quantity of food (and some other things) are responsible for Americans have a shorter life-span than Japanese, the quality our diet does not appear to be the problem. That is, Americans eat too much, but what we eat is actually healthier than what the Japanese eat.

Top 15 causes of death in Japan and the US in order of Japanese relevance.

Top 15 causes of death in Japan and the US in order of Japanese relevance.

Let’s look at top 15 causes of deaths in Japan and the US in order of significance for Japan (2016). The top cause of disease death is the same for Japan and the US: it’s heart disease. Per-capita, 14.5% of Japanese people die of this, and 20.9% of Americans. I suspect the reason that we have more heart disease is that we are more overweight, but the difference is not by that much currently. The Japanese are getting fatter. Similarly, we exceed the Japanese in lung cancer deaths (not by that much) a hold-over of smoking, and by liver disease (not by that much either), a holdover of drinking, I suspect.

Japan exceeds the US in Stroke death (emotional pressure?) and suicide (emotional pressure?) and influenza deaths (climate-related?). The emotional pressure is not something we’d want to emulate. The Japanese work long hours, and face enormous social pressure to look prosperous, even when they are not. There is a male-female imbalance in Japan that is a likely part of the emotional pressure. There is a similar imbalance in China, and a worse one in Qatar. I would expect to see social problems in both in the near future. So far, the Japanese deal with this by alcoholism, something that shows up as liver cancer and cirrhosis. I expect the same in China and Qatar, but have little direct data.

Returning to diet, Japan has more far more stomach cancer deaths than the US; it’s a margin of nine to one. It’s the number 5 killer in Japan, taking 5.08% of Japanese, but only 0.57% of Americans. I suspect the difference is the Japanese love of smoked and raw fish. Other diet-related diseases tell the same story. Japan has double our rate of Colon-rectal cancers, and higher rates of kidney disease, pancreatic cancer, and liver cancer. The conclusion that I draw is that green tea and sushi are not as healthy as you might think. The Japanese would do well to switch the Trump staples of burgers, pizza, fries, and diet coke.

At this point you can ask why our lives are so much shorter than the Japanese, on average. The difference in smoking and weight-related diseases are significant but explain only part of the story. There is also guns. About 0.7% of Americans are killed by guns, compared to 0.07% of Japanese. Still, guns give Americans a not-unjustified sense of safety from worse crime. Then there is traffic death, 1.5% in the US vs 0.5% in Japan. But the biggest single reason that Americans live shorter lives  is drugs. Drugs kill about 1.5% of Americans, but mostly the young and middle ages. They show up in US death statistics mostly as over-dose and unintentional poisoning (overdose deaths), but also contribute to many other problems like dementia in the old. Drugs and poisoning do not shown on the chart above, because the rate of both is insignificant in Japan, but it is the single main cause of US death in middle age Americans.

The king of the killer drugs are the opioids, a problem that was bad in the 60s, the days of Mother’s Little helper, but that have gotten dramatically worse in the last 20 years as the chart above shows. Often it is a doctor who gets us hooked on the opioids. The doctor may think it’s a favor to us to keep us from pain, but it’s also a favor to him since the drug companies give kickbacks. Often people manage to become un-hooked, but then some doctor comes by and re-hooks us up. Unlike LSD or cocaine, opioid drugs strike women and men equally. It is the single major reason we live 5 1/2 years shorter than the Japanese, with a life-span that is shrinking.

Drug overuse seems like the most serious health problem Americans face, and we seem intent on ignoring it. The other major causes of death are declining, but drug-death numbers keep rising. By 2007, more people died of drugs than guns, and nearly as many as from automobile accidents. It’s passed automobile accidents since then. A first suggestion here: do not elect any politician who has taken significant money from the drug companies. A second suggestion: avoid the Japanese diet.
