Wrist blood pressure monitors: Are they accurate? – Mayo Clinic

Wrist blood pressure monitors: Are they accurate? – Mayo Clinic.

That can’t be right.

I had my blood pressure taken at the dentist the other day.  The reading nearly sent me into cardiac arrest.  My observations:

  • The equipment used was a wrist BP monitor, not exactly known for accuracy.
  • The individual who took the reading is a dental hygienist who probably got zero training in the proper positioning and use of the monitor.
  • My blood pressure has always been normal.

I’ll stop at one of those ubiquitous upper arm machines you find at any pharmacy and do a recheck.  And those iPhone apps that measure blood pressure?  Don’t even bother.


Low Vitamin D Causes High BP

Note that this large genetic analysis demonstrated that individuals with genes linked to lower vitamin D levels are more likely to have hypertension mediated by low vitamin D, strengthening the argument for a causal link.

Be aware that the absolute effect of vitamin D levels on blood pressure was negligible, even though statistically significant.

Binge Drinking and HTN

Binge Drinking, Hypertension a Deadly Combo

The report is published in the Aug. 19 online edition of Stroke.

For the study, Ohrr’s team collected data on 6,100 men and women living in a farming community. The researchers followed these people for almost 21 years.

The participants were divided into four groups: nondrinkers, non-binge drinkers, moderate binge drinkers (defined as having six or more drinks on one occasion), and heavy binge drinkers (defined as having 12 or more drinks on one occasion).

Among the men with high blood pressure, 17.8 percent were moderate binge drinkers, and 3.9 percent were heavy binge drinkers (a percentage similar to the men with normal blood pressure). As for the women, there were too few who said they were binge drinkers to be able to draw conclusions, the researchers said.

Ohrr’s group found that compared with nondrinkers, the risk of stroke among men with high blood pressure was increased threefold. If these men drank six or more drinks at one time, their risk for stroke increased fourfold, and with 12 drinks or more, the risk rose 12-fold.
