Undiagnosed and untreated - what's your blood pressure?

Last week, the focus was global hypertension problems. Now, in a North American study, we learn that high blood pressure is often undiagnosed, untreated:
For the study, the researchers measured the blood pressure of almost 1,100 volunteers. The measurements were taken at mobile clinics that the researchers had set up at shopping malls, workplaces, hospitals and community centers in a large city.
The study revealed that 50 percent of the participants were unaware they had high blood pressure. Of these people, 2 percent were at very high risk for health complications.
The findings were published online Jan. 5 in the American Journal of Hypertension.
"What is particularly significant about this study is that a surprisingly large number of participants exhibited some type of hypertensive urgency or emergency," study author Dr. Grant Pierce said in a journal news release. Pierce is executive director of research at St. Boniface Hospital in Winnipeg.
Most of the people with high blood pressure weren't being treated even if they had been diagnosed. The study authors suggested that either these people didn't fully understand their condition, or they didn't understand the health consequences associated with high blood pressure.
High blood pressure is the leading cause of strokes. Taking it seriously might save a life.

The world is experiencing a high blood pressure increase

High blood pressure - hypertension - is the leading risk factor for strokes.

So the news is a little frightening - high blood pressure is increasing worldwide:
"There are almost 900 million people in the world with hypertension, and there are almost 3.5 billion people with elevated blood pressure that doesn't quite meet the definition of hypertension," said study lead author Christopher Murray. He directs the University of Washington's Institute for Health Metrics and Evaluation in Seattle.
"Blood pressure is the leading cause of premature death and disability in the world," Murray said.
Blood pressure is made up of two numbers. The top number, called systolic pressure, measures the pressure in the arteries when blood is being pumped from the heart. The bottom number, the diastolic pressure, measures pressure between heartbeats. Blood pressure is expressed in millimeters of mercury (mm Hg).
The study authors said that even systolic blood pressure within what is considered a normal range -- less than 120/80 mm Hg, according to the American Heart Association -- can increase the risk of heart attack and stroke.
It's important to pay attention to your blood pressure and if needed, work with your health professionals to control it.

Top posts visited in 2016

Stroke of Faith has been around since December 2005 - more than 11 years now.

I ran numbers recently for the top five most-read postings in 2016. Just one was actually posted that year - the rest are a collection of oldies but goodies starting with:

1. There's a hole in my heart 

2. Stroke signs: Remember the first three letters, S. T. R.

3. 'Do not be anxious about anything'

4. 'Be our strength every morning'

5. How I learned about aphasia and intelligence - the hard way

The top most-read posting is about the likely cause of my stroke - a patent foramen ovale, or a hole between the two upper chambers of my heart. The second is a quick read about stroke signs. Numbers 3 and 4 are Scripture-based postings, and No. 5, the only one posted in 2016, reminds us all that aphasia effects language - but doesn't reduce intelligence.
