10 things I didn’t know about angioplasty until I read this book

1 Dec

by Carolyn Thomas    ♥  @HeartSisters

Being asked to write a book review is largely a royal pain. Authors hope you will be kind, while you hope the book at best might tell you something that every other book for heart patients hasn’t already told you. I frequently write here about books I like reading, but I won’t write about books I don’t – a waste of the very limited hours I have left on this earth, preferring instead to simply ignore them. As my late friend and co-author Jill Stewart Bowen used to say of our first book project together:

“The mediocre they can find for themselves.”

Perhaps that’s why a review copy of the book called Your Personal Guide: Angioplasty* sat on my coffee table for weeks (looking quite smart nestled on top of a pile of other heart books next to the candle centrepiece, I thought).  One day, I finally got tired of looking at this latest addition to my living room decor and decided to give it a go.  And within a very few pages, I learned some fascinating things I didn’t know before.  

These included:

1.  It’s possible to have significant coronary artery disease (CAD) with multiple blockages greater than 70% yet have no symptoms of angina on exertion.  This is called a silent heart attack, and in many cases can happen to people who are very sedentary (because they don’t exert themselves enough to challenge their heart muscle).

2.  Heart attacks are usually triggered by unstable coronary artery blockages of less than 70% which don’t cause any symptoms. In fact, only 20-30% of heart attacks occur at the site of an artery that’s more than 70% blocked. If you have one blocked artery causing you chest pain and other cardiac symptoms, it is virtually certain that this is merely the tip of the iceberg.

3.  When you have a blockage in a coronary artery, Emergency Department staff may administer clot-busting drugs, especially if your hospital isn’t equipped to perform emergency angioplasty procedures to help re-open that artery. Clot busters, however, have only a 50-60% success rate.

4. The word “stent” comes from its creator, Charles Stent (1807-1885), an English dentist who invented a compound to produce dentures and other things like skin grafts and hollow tubes (essentially what a metal coronary stent is).  His real claim to fame occurred when he suggested using his material to coat underwater trans-Atlantic cable, which had broken several times as a result of corrosion by seawater.

5.  Most coronary stents start out as a solid, hollow tube.  The openings (a lattice-like chicken wire effect) are then created with laser cuts, although some newer stents are braided from individual thin metal wires. It’s a design intended to keep the stent flexible enough to navigate the twists and turns of our coronary arteries.

6.  The air pressure in your fully inflated car tires is about 2 atmospheres. By comparison, the high pressure used to inflate a balloon inside a coronary artery during angioplasty is between 10-20 atmospheres.

7.  Angioplasty is not generally recommended for blockages below 70%. There is no proven benefit in implanting a stent in a blockage that does not impair blood flow to the heart muscle. These blockages require only medications and lifestyle changes to treat successfully.

8.  There is no cure for the chronic condition called coronary artery disease (CAD). Once plaque has built up in your arteries, it is very difficult to eliminate. Embracing a healthy lifestyle can help control CAD, but remember that the word “control” here means “stopping the progression of the disease”.

9.  If you have a significant coronary artery blockage (more than 70% blocked) , it’s a red flag that more blockages can happen at any time in the future.  In fact, once a critical blockage like this is identified, it means you already have plaque buildup and minor blockages in many, many arteries of your heart that can significantly increase your chances of having a heart attack.

10. Up to 30% of those who have had stents implanted or open heart bypass surgery still experience angina afterwards.

This book is co-written by Dr. Allen Jeremias, a cardiologist with impressive career credentials. The format is loosely based on the varied experiences and 36 questions of five fictional but true-to-life heart patients: Brian, Michael, Diane, Rosa and Reginald. It’s a clever idea, but does mean that useful information may not be as accessible as it would be in a more topically-organized format.  You virtually have to read the entire book cover to cover to make sure you catch all references to each important area. I know that many patients, however, often use heart books (or Dr. Google) to look up the answer to one key question they may have at one particular moment. The good news: the book is an easy read, so jam-packed with factual and useful information that you’ll have no trouble reading the entire book straight through. I did it in virtually one sitting.

Responses to each of the questions posed by the five fictional patients are generally those typical of  patients facing angioplasty (although do so many of them have to be smokers?) Answers to the questions are divided into two sections:

  • The Bottom Line (basic important information)
  • The Nitty Gritty (additional info in more detail)

While the book’s 248 pages go into impressive detail for any patients who have already undergone (or are scheduled for) angioplasty procedures, there remain at least a couple of areas of unfortunate omission.

First, I was surprised to discover that despite the fact that one of the book’s co-authors (Dr. Susan Bartell) is a psychologist, the psychosocial impact of being diagnosed with heart disease is virtually ignored here.

In fact, I could find only one reference to this debilitating fallout common among so many heart patients, and that one reference is buried in a single paragraph in the “What About Sex?” section about halfway through the book:

“Aside from receiving medical clearance to engage in sexual activity, it is important to note that many individuals with coronary artery disease experience anxiety or depression as a result of the diagnosis. These feelings often come from being confronted with a life-or-death situation (especially after a heart attack).  These strong emotional responses (especially depression) can contribute to decreased sexual desire or a reduced ability to perform sexually.”

But narrowly limiting this too-brief overview to the sex chapter unfortunately dismisses critically important issues that can be so damaging to overall health recovery following a cardiac event. (Mayo Clinic cardiologists, for example,  estimate that up to 65% of newly diagnosed heart patients experience depression, yet fewer than 10% of these cases are appropriately identified).

I’m not a psychologist, but I’ve written more about heart disease and mental health issues on this one little blog than this book from two experts even begins to cover.

This is a serious gap in a book that includes, for instance, page after page of very sound exercise recommendations for those diagnosed with coronary artery disease. We know that one of the inevitable consequences experienced by heart patients who are suffering from depression is a severely impaired ability to follow the very exercise and lifestyle improvements recommended here.  Readers keen to learn more about coping with these psychosocial issues known to be associated with a diagnosis of heart disease would do well to instead seek out Dr. Wayne Sotile‘s very useful book called Thriving With Heart Disease.

Secondly, I may have missed this, but I could find no mention here of implanting stents in patients who survive heart attacks caused by Spontaneous Coronary Artery Dissection (SCAD).  No longer considered a rare disease, this often deadly diagnosis usually strikes young, healthy females with few if any cardiac risk factors. It’s now more correctly thought to be an under-diagnosed disease – not rare – and thus needs to be included in any book that covers angioplasty.  Mayo Clinic, for example, has undertaken two important SCAD research trials on this deadly condition.

I’d love to see these omissions addressed in future editions of an otherwise excellent basic resource for heart patients and those who care about them.

This user-friendly book does a solid job of clearly describing cardiac diagnostic tests, angioplasty and other invasive cardiac procedure options, risk factors and heart disease symptoms – all helpfully illustrated throughout with easy-to-understand drawings. It would be especially useful to worried patients who are scheduled for angioplasty at some point in the near future,  and want a comprehensive overview to help them prepare.

For these reasons, it deserves a permanent spot in my bookshelf of heart books.

    How to get this book?

    Angiogram necessary? Lately I’ve been experiencing breathlessness upon exertion (also have had well-controlled permanent atrial fibrillation for years), so my electrocardiologist recommended a nuclear stress test (results were positive, but not necessarily definitive and could have been a false positive). So now he’s ordered a wrist angiogram (with angioplasty if needed). But I’ve been reading a lot of recent information that too many angiograms/plasties are unnecessary . . . and maybe even harmful. I’d rather try lifestyle changes. Am I being prudent? (Note: I also had an echo last year and there were no major problems.)

      Hi Judith – I’m not a physician so cannot comment specifically on your case, but I can tell you in general that these two cardiac tests (echo and angio) look for different things e.g. an echocardiogram checks on the walls of the heart chambers, weak areas of heart muscle, how efficiently your heart is pumping, valve function, etc. – but doesn’t generally spot coronary artery blockages, which the angiogram is looking for. Good for you for doing your homework – talk to your doctor about your concerns and the option of how lifestyle changes might address your decisions. Best of luck to you…


      • Judith Toler March 8, 2016 at 4:10 pm #

        Dear Carolyn — Thank you so much for your website and for your swift response to my question. I will defer having the angiogram until I can have a discussion with my doctor. When he gave the order (immediately after the stress test), I was too ignorant about the procedure to ask any questions–and he didn’t give any information other than that the procedure was highly safe.

          Hi again Judith – – Nobody should ever agree to undergo any invasive medical procedure when they’re feeling uninformed about it, and no doctor should give so little basic information that the patient remains uninformed when they walk out the door. Very good plan to discuss this further with your doctor, but in the meantime, your job is to become the world expert in what’s going on with the only heart you have. Consider browsing the Mayo Clinic website, for example, which is a credible trusted site to get you started.

    Hello Carolyn. I too cannot believe that a book about an invasive cardiac intervention like angioplasty contains very little about the known mental health issues that so often accompany/follow it – inexcusable, really, considering that one of the co-authors appears to be a mental health practitioner. The medical profession has been far too slow in recognizing the profound impact that heart disease can have on the whole person – an impact that then impacts our patients’ ability to engage in any of our heart-healthy recommendations. We rely on mental health professionals to help educate both patients and physicians on this problem.

    Thanks VERY MUCH for recommending Dr. Sotile’s book here. I believe it’s out of print now, but I can still find it in used bookstores or online; I like to hand copies out to recently diagnosed heart patients, regardless of their specific procedure.

    Sadly, this angio book does little to enlighten those who don’t get it yet. I wonder when the second (REVISED) edition is planned? I’ll wait until then before recommending it to our clinic patients.

      Thank you RN – I too am hopeful that this book will soon be edited to include what you’re recommending.

    Reblogged this on Rehabilitate Your Heart and commented:
    “Very good point for all heart patients to know. Especially the points that it isn’t cured by intervention, and that symptoms may continue in spite of intervention.”

      Thanks Elizabeth!

    Re: #8 – no cure. Are you familiar with the work done by Dean Ornish, M.D? I know his books, on the surface, sound just like another “program” but his work with heart patients has shown that CAD can be reversed with diet, exercise and people connection.

    I saw him speak when his initial study in Texas was just beginning and even in the beginning weeks they were seeing result. It’s since been replicated.

    The biggest problem is people aren’t willing to do life-style change, and consider a vegetarian diet, meditation, yoga/aerobic and group therapy too difficult to embrace.

    Ornish is very clear that all four things need to occur as all four are of equal importance.

    Sounds like this book focused on just the car parts and not the emotional engine which we now know makes the car run, stall or die.

    Thanks for a good review!


    • Carolyn Thomas December 2, 2012 at 4:50 am #

      Yes, I’m familiar with Dr. Ornish.

      “…focused on just the car parts and not the emotional engine which we now know makes the car run, stall or die.” Ironically, that observation about this book is also often the concern expressed about the Ornish program. The reality seems to be that few heart patients are actually able to successfully stick to all four requirements of the severely restrictive Ornish plan longterm – for exactly the reasons you mention.

      As another of my readers once commented about the Ornish plan: “I’m already a vegan and I can’t follow this. No simple carbs, ever??? No thanks! I prefer Dr. Oetker to Dr. Ornish – mmmm muffins.”


      • MentalMakeovers December 2, 2012 at 9:46 am #

        I agree that simple carbs may be one of God’s greatest gifts!

        I also think that living in “the land of milk and honey” is both a blessing and a curse. We (read “I”) have so many temptations that most people of the world do not have – we both prosper from them and suffer with them.


        • Carolyn Thomas December 2, 2012 at 9:56 am #

          Sadly, yes. But our prosperous way of eating is spreading! A few years ago, I covered here a study from Uganda in which researchers from the Mbale School of Hygiene said: “Uganda’s growing urban population now bears the brunt of increasing rates of chronic illnesses such as cardiovascular disease and diabetes as they follow a shift away from Uganda’s traditional and unprocessed diet and towards a more Western diet of high salt, high-sugar and high fat processed foods.” Sigh….

            The good news is the impoverished people in the world will live longer due to the wonderful aspects of modern medicine gradually being introduced. The bad news they will live longer with chronic medical problems.

            If given a choice, I’d probably take my chronic conditions for a longer life . . . it’s an interesting conundrum.


  9. Vetia December 1, 2012 at 7:20 pm #

    Very good information as always but very bad timing. I was afraid that you would give me information that I didn’t want to know right now as I have been given a date for another cardiac cath. Oh what fun.


    • Carolyn Thomas December 1, 2012 at 7:36 pm #

      Actually, this might be very good timing, Robin. If you can get your hands on this book before your next visit to the cath lab, I think you would likely feel informed and reassured.


  10. Mary December 1, 2012 at 9:17 am #

    Carolyn, Very enlightening as always. I’m wondering if there’s any coverage of vasospasm both in the course of angiogram or day to day. Since this book is targeted to angiography, does it cover day to day vasospasm or forms of irregular beats, arrhythmias, etc. These are a part of some people’s experience, particularly as heart disease progresses.


    • Carolyn Thomas December 1, 2012 at 7:17 pm #

      Hello Mary – not really. This book includes only a brief reference to arrhythmia and its link with smoking. The focus is primarily on uncomplicated angioplasty here. There is a section in the book called “Can Anything Go Wrong During the Angioplasty Procedure?” that includes risks like reaction to the dye used, bleeding, etc. but no mention of vasoconstriction (which we know has been reported, sometimes catheter-induced).


  11. granny annie December 1, 2012 at 5:04 am #

    Thank you, thank you for this excellent information. I wondered where the term “stent” came from as well as everything else.


    • Carolyn Thomas December 1, 2012 at 5:29 am #

      Me too. Who knew that stent was named after a person?
