With All my Heart: Hypertension and Heart Health (Part 2)

Last week we talked about global body shipping and how high blood pressure (also called hypertension) can damage our body. This week we’ll look at the leading causes of hypertension and what we can do about them.

Atherosclerosis – This is a big word that I like to call Gather-old-Playdoh-sis. You know how new Playdoh is soft and pliable and so pretty you just want to eat it? That’s how blood vessels are supposed to be. Over time Playdoh hardens and shrinks as it dries out and that’s what happens in your blood vessels. Blood vessel linings gets pot holes, cholesterol fills in the pot holes and hardens there like Playdoh, and then your blood vessel can’t expand and contract easily like it used to.

Atherosclerosis can be prevented or slowed by exercising and eating a diet high in plant parts. Diet and exercise prevent pot holes from forming and reduce the amount of fat Playdoh in the blood looking for a pot hole. Science isn’t sure if hypertension increases atherosclerosis or if atherosclerosis increases hypertension. They do know that exercise and eating greens helps decrease both. It’s kind of like the “What came first: the chicken or the egg?” debate. Answer? Doesn’t matter; they’re both delicious. Eat your greens and move your body and don’t worry about it.

Sleep Apnea – More than half of people with hypertension also have sleep apnea, so scientists are pretty sure there’s a connection. (Let’s face it: when we talk about the human body, there is always a connection.) High blood pressure can trigger sleep apnea which causes poor sleep or a lack of sleep which raises your blood pressure which can trigger sleep apnea. A doctor can direct you to a helpful mask to improve your sleep. You can also lose weight and exercise.

Smoking and Drinking – Stop smoking and don’t drink more than 1-2 alcoholic drinks per day. Yes, I am a party pooper.

Too much salt – Remember how your blood vessel walls are made of smooth muscle? Blood pressure is all about those wall muscles being able to relax to let blood flow. For the walls to relax and contract regularly, they need regulators: namely the Three Musketeers (or the Three MagCalPots): magnesium, calcium, and potassium. There is a connection between hypertension and insufficient magnesium, calcium, and potassium and it may have something to do with salt.

You see, Salt is supposed to be the fourth musketeer, but he went off and recruited so many many many of his friends that they turned evil and wrought havoc. The Three Musketeers must be present to balance out Salt and his friends; if there aren’t enough of the Three MagCalPots, then Salt wins and blood pressure goes up. You can help the Musketeers by putting less salt and more magnesium, calcium, and potassium in your mouth.

By the way, it’s recommended that you eat no more than 1 teaspoon (2300 mg) of sodium (salt) each day. The ideal goal is 1500 mg, but Americans eat so much sodium that even cutting down to 2300 is a plus. Be aware that 75% of the sodium most of us eat is in processed, pre-packaged, and restaurant foods, not the salt shaker.

Genetics and Family History – hypertension runs in the family. If hypertension runs in your family, it’s even more important that you exercise and eat well. Sorry. Maybe you also inherited a sharp wit or great hair.

 

Note: I should to point out that the medical community isn’t 100% sure what causes hypertension. They observe connections between hypertension and heart attacks, atherosclerosis, sleep apnea, etc., and make highly educated guesses. They also observe the connections between healthy habits and improved hypertension and make highly educated recommendations. What is 100% certain? We can take hypertension as the warning sign it is and make healthy changes.

 

We were under great pressure, far beyond our ability to endure, so that we despaired of life itself. But this happened that we might not rely on ourselves but on God, who raises the dead.  2 Corinthians 1:8b, 9b

With All my Heart: Hypertension and Heart Health

Ever wonder why you have a pulse? Obviously your pulse is there because your heart is pumping, but why can you feel it? Why does the blood vessel push against your fingers for a moment and then disappear under your skin?

The simple answer is that your blood vessels are flexible, not stiff. As the blood from the heart pumps through, the blood vessel can expand like a balloon and then shrink back as the blood passes. Unlike a balloon, the blood vessel doesn’t get stretched out with each expansion because the walls of the vessel are mostly made of smooth muscles that contract or squeeze back into shape again. The expand and contract pattern with each pump of the heart keeps the blood under pressure so that it flows in one direction. It’s like a water slide adjusting to each rider as she passes.

heart bp1These smooth muscles move involuntarily (i.e. you can’t control them like an arm or a finger) to regulate the volume of blood in the vessel and how forcefully that blood flows. Blood vessels are not passive garden hoses but more like millions of tiny fans keeping the wave going in a tubular stadium. This is mind blowingly cool, but what does it have to do with hypertension and heart health?

When the smooth muscles in the blood vessel walls contract too much, they become stiff and tense or, if you will, “hyper tense” which causes the blood pressure to rise. Hypertension is another name for high blood pressure and contributes in a big way to heart disease. Statistics say that if 10 people have untreated hypertension, 5 of them will die of a heart attack and 3 of them will die of a stroke. Hypertension is dangerous if left untreated, but why?

heart bp2Hypertension is a warning sign that blood is not flowing well in the body. Blood pressure goes up because the blood has to press harder to get through the vessels, i.e. the heart pumps extra hard. In our shipping analogy, hypertension is all of the sailors working harder and harder to get the ships to the docks, but not getting there any faster than they used to. After years of hard sailing, shipments are delayed or detoured and the sailors simply can’t sail up every tiny tributary like they used to because the way is clogged with pollution or traffic. Any body part of the world that receives fewer shipments than necessary will suffer. Another way to say it is that if a body part lacks blood, it also lacks oxygen which it needs for energy producing reactions within the cells, so it will not have energy and cells will die. If enough cells die, we develop symptoms.

Let’s take a trip around the body globe. Yes, I know the analogy is wearing thin, but I’m up a creek and dropped my paddle, so you’ll just have to drift downstream with me.

North America is the heart because “home is where the heart is” and my home is in North America. (Feel free to print out the map and draw your heart wherever you want.) If blood shipments to North America stop completely, the Earth dies; this is a heart attack. If the shipments slow down enough to almost stop, North America riots which causes pain; this is a heart attack that doesn’t kill you but gives you a chance to change. About half of people with untreated hypertension end up with a heart attack.

Asia is known for electronics manufacturing, so it represents our brain. The brain has been compared to a computer and we think about (or maybe with) our electronics a scary lot of the time. If shipping to Asia brain is cut off, we have a stroke. Maybe we die and maybe we just have some brain damage, but either way we suffer without our electronics. Poor blood flow in the brain can even cause vascular dementia. About one third of people with untreated hypertension end up having a stroke.

heart bp3Africa is home to the Sahara Desert which has the most uninterrupted view in the world (I’m guessing) from the top of a dune on a cloudless day. Africa represents our eyes and hypertension is a sand storm. Eyes need nourishing blood to see properly and when they don’t get enough, vision can become blurry or be lost completely.

South America is home to the Amazon River which processes a LOT of water so South America represents our kidneys which process and clean our blood. If the blood vessels inside of or leading to the kidneys are damaged, the blood can’t get in and flow through to be cleaned. The Amazon River becomes polluted and we need dialysis or die. The number one cause of kidney failure is high blood pressure.

Europe is the bones of the world because they have the most stone castles which are kind of like skeletons because they provided structure and protection in feudal society…stone and bone rhyme, shall we just go with that? Hypertension can lead to bone loss and osteoporosis because calcium is recruited from the bones to patch up tiny tears in the blood vessel lining.

Sorry, Australia, I’m out of body parts! I’m sure hypertension would ruin you too, though.

Hypertension normally takes many years to cause damage and not everyone will suffer the same symptoms or any symptoms at all. But I now understand why blood pressure is considered important enough to be checked regularly as a “vital sign”. Next week we’ll look at what we can do to help reduce hypertension.
