My Heart Live! On Screen!



By Susan Esther Barnes

When I was in college, I received a letter saying I had been randomly selected to participate in a medical study called Cardia which was being conducted in four cities in the US. The purpose of the study was to learn about how heart disease develops in young adults.

What they didn't tell us at the time, or perhaps I wasn't paying attention, was that if they could get ongoing funding, their intention was to keep track of us throughout our lives, testing us every few years, and seeing who among us was developing heart disease so they could compare their test results with those of us whose hearts are still going strong.

This explains why, recently, I found myself in the room pictured above, with the cool lions should lie down with lambs poster, getting an echocardiogram. Rather than just the boring test we've all seen that produces nothing more than a wavy line on a piece of paper, this test included the use of sound waves to show the structure and functioning of my heart on a computer screen.

So I got to lie there, looking at the different chambers in my heart pumping, and my heart valves opening and closing, in real time. They also do some cool color coding so I could see the speed and direction of the blood flow (just with sound waves, without pumping any yucky stuff into me), so I could actually see the blood flowing from my lungs into one chamber, the valve closing, and another valve opening while the chamber contracted and pushed the blood out into my body. Too cool.

Of course I started by describing the most fun part, and skipped over some other parts, like the four multi-page consent forms I had to sign, the multiple vials of blood they took, and the glucose tolerance test that includes drinking a bottle of sickly sweet orange drink which probably had about 8 million calories and left my stomach feeling angry for hours.

On the upside, though, the lab staff was great, and kept me well distracted while they were taking my blood. Which is a good thing, because if they let me brood on what they're doing, my blood pressure drops, and in past years they've had to stroke my arm to try to squeeze enough blood out into the tubes. And we won't talk about the one year when they assaulted me with smelling salts.

This year they didn't do anything like they had in the past to try to raise our blood pressure to see how high it would go. The most effective method they have of doing this is the treadmill test, which keeps raising the angle and speed until you cry "Uncle!"

One year they tried to make us play the (not so old at the time) "Breakout" video game (basically using a "paddle" to make a bouncing "ball" break a "wall"), but so many of us were so bad at the game we lost before they had time to take our blood pressure. Another time, they had us hold our arm in a bucket of icewater for 60 seconds. It may not sound like a big deal, but you try it some time. It was so painful a bunch of the study participants threatened to never come back, and they had to promise us they would never do it again.

As they like to remind us from time to time, the longer the study goes on, the more precious and irreplaceable we are. There is no other group they can draw from that has this same pool of data from the last 25 years.



Yes, at the risk of dating myself, as the T-shirt says, this study has been going on for 25 years now. But they're not always testing the same things. For instance, the heart function test I mentioned above tested for some factors that are now known to be indicators of heart disease, but included some new measurements they think might be predictive, and are gathering data on now.

This year, for the first time (that I recall), they did a congnitive test, which included asking me to listen to a long list of random words and then repeat back as many of them as I could remember. They did this a few times with the same list of words, and then did it once with a second list of words. Then they got all tricky on me asked me to go back and say as many words as I could from the first list without me saying any of the words on the second list.

Lucky me, it turns out that I qualify for a brain MRI test they also want to do, so I get to go do that and a CTI scan of my heart next month.

It's all a bit inconvenient, but it's a mitzvah, I do get to see some cool test results, and I feel good about contributing to medical knowledge that could help future generations live longer (and has already resulted in a bunch of publications). Plus, I can't say enough about how professional, helpful and friendly all the Cardia staff are.

So stay healthy, and the next time you read about a study that shows a new way to predict or prevent heart disease, think of me!

Chevra Kadisha Seminar - The Experience

By Susan Esther Barnes

Below is Part One of a two-part post about a seminar I attended. I'm posting it in two parts since each post looks at the seminar from a different perspective. This one is about the experience and the second one is about the knowledge I gained.

***************

On Sunday afternoon I attended a Chevra Kadisha (generally translated as “holy society”) seminar. It was an introductory lecture on taharah, the Jewish method of ritually washing dead people to prepare them for burial. It was an uncomfortable experience for me, in more ways than one.

When I arrived, I walked into a large room set up with tables and chairs. On the far side of the room were two women and a man seated at one of the tables. I walked over to them to confirm I was in the right place for the seminar. They invited me to have a seat.

More people came in, and they naturally gravitated to our table. In time, there were eleven of us gathered there, chatting amiably. That’s when the man who’d been there from the start said, “It looks like we might get enough for a minyan. If we do, we can daven.” (“Daven” means to say Jewish liturgical prayers, some of which require a “minyan” of ten Jews to say).

From my perspective, we already had a minyan, because there were at least ten Jewish people present. But by his statement this man was declaring he only counts men in a minyan. Without giving it a second thought, this man was telling me, and the other women at the table, that we don’t count. None of us said anything, but I think he picked up the change in body language from some of us, because a short time later he said some things such as he knew some of us were “liberated women.”

The point is, because of this comment, before the seminar even started, I felt uncomfortable. Since taharah is not common among Reform Jews, I started to think, “As I do this am I going to run into a lot of similar situations in which I feel like I’m being put down in some way because my customs are different?”

Aside from the cultural concerns that arose immediately before the seminar, my main source of discomfort during the seminar was caused by the talk of things like blood and mucus and oozing. My husband would probably think it serves me right, because whenever I have a cold or some other malady I want to describe it to him in great detail, and he does not want to hear a bit of it.

The fact is, I needed to hear about the blood and the mucus and the oozing. I still need to hear a lot more about it. This is because my biggest fear about trying to do taharah is there’s a very real possibility that when I see the blood or the mucus or the oozing, I might need to sit down and put my head between my knees in order to prevent myself from passing out. I say this based on past experience.

Frankly, it’s mostly the blood I’m worried about. The good news is, the woman sitting next to me said she’s been doing this for about ten years and so far she hasn’t encountered anyone who has had a violent death. So she hasn’t seen a lot of blood or similar unpleasantness.

Nevertheless, it’s clear I’m not going to be able to do taharah unless I can somehow desensitize myself to some extent to my natural reaction to blood. It’s going to be a bit hard to ritually wash someone while I have my head between my knees. The best way I know to desensitize myself, as with any irrational fear, is to approach it close enough to get uncomfortable, back away, talk about it, calm down, and then repeat the process as often as necessary. This seminar was one step in this process.

So although the content of the seminar may have been things I could have read in a book, my attendance at the seminar provided me with two important experiences: The realization that I need to prepare myself for encounters with people who observe different Jewish customs than I do, and a chance to approach my fears about blood. Not a pleasant way to spend the afternoon, but certainly one that was worthwhile.
