Cath #4

Here we are again... A new cardiologist, a new medical system, another cath. This one was as much a test for the new team to familiarize themselves with my long-standing coronary artery disease, as much as my need to understand whether the new symptoms that I have been feeling and some of the bad blood test results that I have been receiving were because of new blockages in my coronary arteries. 


Since my first cath, when I was 30 (hard to believe that was almost 20 years ago), all the cardiologists I have seen have told me that my coronary artery disease (CAD) is so advanced and my cholesterol is so far from my target that the only reliable way to know for sure whether my arteries will need intervention, before a major event would happen, would be through a cath. They almost all recommended that I would have a cath every 5 years. 


The previous cardiologist that I had until earlier this year (for 6 years) was too nervous to do a cath at the 5 year mark because he said with the amount of artery disease that he was sure  I had it would not be prudent to have a cath, to not “dislodge something” (his words). 


But my cardiac symptoms have continued to change and not for the better. 


For a couple of years now, my shortness of breath has worsened. Even when I do light chores around the house, like carrying a laundry basket the 20 or so feet from my bedroom to the laundry room, I am breathless. My BNP (which, in layman’s terms, is a measure of the degree of heart failure your heart is in) has gone up to 700 pg/ml (normally, the target is under 100 pg/ml), but it has been fluctuating, too - anywhere from 200 to 700 pg/ml. 


My chest pressure is more intense when I exercise - not necessarily only in my chest, but my left arm, shoulder, shoulder blade and the left side of my neck all go numb and they feel like someone is stopping circulation to them or strangling me. It’s a scary feeling and it happens virtually every time I go for a brisk walk, climb even a small hill or walk in the heat. 


My blood pressure has worsened but I am controlling it better now with a drug that (finally!) works, after months of trial and error with many new and old drugs. 


Typically, even when they don’t recommend a cath every so often to determine CAD, they do recommend a cath when your symptoms or your heart blood tests are worsening. But even with all these changes, the previous cardiologist refused to do another cath. 


The new cardiologist agreed that it would probably be beneficial to do one. He skipped the stress test with contrast because he said we already know I have CAD. And whether the stress test comes back perfect, inconclusive, or modified, he would still follow it up with a cath. Somehow, through some kind of magic, he got the cath approved with the insurance (they typically want a less invasive and cheaper test before they approve the cath). 



After the procedure, right leg still flat, but ready for the IV to come out.


So, off to the cath lab we go. Everything went according to plan, and it was great to report that there is not much change in the status of my arteries since the last time they did the cath with my previous team, 6 years ago. 


The main findings were:

  • the LAD (Left Anterior Descending, aka “the widow maker”) is still at 50% blocked, but that is open enough to not require any intervention at this time. All the segments of this main branch are listed with “no significant stenosis”. Since this artery irrigates pretty much the entire left side of your heart (which is “the pump”, responsible for sending blood to your entire body), this artery is the workhorse of the heart. So, it’s good news that, although it is diseased, it provides accurate flow to the heart. He made no special mention about the bypass graft for the LAD which was put in place 8 years ago when I had my open-heart surgery. The cath I had 6 years ago does not speak about the LAD graft/ bypass either, although it mentioned other grafts (I had four arteries bypassed) as either being open or completely occluded. 

  • the Left Circumflex artery shows “no significant” stenosis in all its segments. 
  • one of the Obtuse Marginal arteries (which irrigates the upper part of the heart and is one of the branches of the Left Circumflex artery is between 80-90% blocked. The bypass put in place when I had my surgery is completely (100%) closed. 
  • there are two other arteries (the Left Posterior Descending and the Right Coronary) that are described as “small”, but without any mention of any disease. 


Their overall assessment is that, indeed, there is “existing advanced coronary artery disease” (the doctor even called it “aggressive”), but that at this time nothing requires an intervention and the disease seems to be stable from 6 years ago. 


This new interventional cardiologist (my regular cardiologist is not an interventional one, so he does not perform caths or any other procedures) was the first doctor that did not advise to keep getting caths every 5 years. He said to only get one when symptoms change. Which ... is relative, in my book. Like I said above - the symptoms have changed. However, the cath did not seem to reveal anything new. So, while I am thrilled that there is no new or more severe disease, the questions of the causes for the new shortness of breath, increased chest pressure, higher blood pressure and a higher level of BNP still remain. 


The cath lab doctors did recommend increasing one of my blood pressure medicines (Amlodipine) from 5 mg/ day to 7.5 mg/day, but I will wait to also chat with my regular cardiologist before I do that, as he prescribed a diuretic instead, for the same symptoms. So, I need to review with him my meds, my symptoms and my cath findings as he is more familiar with my larger heart condition than a doctor who saw me for 25 minutes in the cath lab. Making this decision to wait before making changes to my meds is something I have done often. I want the doctor with the most knowledge about me, about my personal case and history, about my extensive file of heart disease and hypercholesterolemia to be in charge of all the changes in my meds after we sit down and together explore the best approach and outcome. 


A word about the procedure itself: 


Everyone will tell you that a cath is not a walk in the park. It’s inconvenient, invasive, somewhat traumatic if you are intimidated by doctors and hospitals and needles; it’s kinda scary because it does come with risks, like any procedure and with side effects depending on the drugs they give you, or the treatment they might perform while you’re in the lab, or depending on how well the healing is going after you go home. But having done four caths, all at different labs and by different doctors, I am not scared of them anymore. 


You come to the hospital early (before daybreak, usually), you get into hospital clothes (all street clothes must go), you get your own bay in a long ward, complete with your own machines, a tv and a call button for the nurse. You get an IV put in, a couple of nurses and doctors come and take vitals from you and ask you about 10,000 questions. 


And then, they do some blood tests. Usually a complete metabolic panel (CMP) to look especially for infections or kidney problems, and I get an INR which shows whether your blood clotting number is normal. Four days before the cath I had to stop my blood thinner medication (Warfarin) so that the femoral artery that they access the heart through can heal after the procedure. They look for kidney problems because they use dye. You must have healthy kidneys so your body can flush it out after the test is done. Sometimes they give you saline through the IV after the test to speed out the elimination of the dye. But they didn’t do this this time. They just told me to drink a lot of water after I leave. 


After the tests and the interrogation are over, they wheel you in the cath lab which looks like an operating room that you see in the movies. They put you on this table and there is a huge TV next to you, where they will see your arteries. They usually give you sedation to relax you and so you won’t care about what is going on. But every time I have gotten a cath I have insisted on not getting sedation, because I want to be aware of what is going on and be able to speak with the doctors about the findings as they see them. This time was no different: I got no sedation and the nurse said he did not hear of anything like it. “What do you mean no sedation?” The recovery time is shorter if you get no sedation. 


They give you some local anesthesia at the top of your leg, in the groin area, and then they make a tiny slit in your femoral artery through which they insert a sheath through which they will insert catheters of various calibers that will go all the way to the arteries of your heart. You have a small X-ray-looking machine above your chest that I am assuming shows pictures of the catheter going through the arteries on the big TV screen. Once there, they inject dye and they look on the screen to follow the flow of the blood through the arteries. 


I had two doctors this time - one was the attending (he mostly supervised and shouted out the findings) and the other one was a fellow who actually performed the procedure. The attending spoke with me the whole time. 


Although you do get a local anesthesia, you do feel some sort of pressure while they maneuver the catheter inside the femoral artery. This cath was hands-down the most painful of all the ones I have gotten. But I still didn’t ask for any other tranquilizers or anesthesia. It was over in 30 minutes. 


After the procedure, you have to rest flat on your back for an hour, after a specialized nurse removes the sheath from your artery and applies massive pressure to stop the bleeding. After an hour of lying flat, they let you lift your head and recline, but you still cannot bend your leg for an hour. After that, they want you to walk around the long ward. After another hour of paperwork and advice on what to do home, you leave. I was at the hospital at 6.30 AM. We made it back home around 2 PM the same day. This was the first time when I did not leave the hospital in a wheel chair, but they told me that’s because I didn’t have any sedation, so the risk of being dizzy or unstable was very small. However, I do have artery disease, something could have been dislodged or cause a blockage or clot in the wrong vessel - but they didn’t seem too concerned with this. 


In the end, I am glad we did the cath. It put my mind at ease somewhat that no new blockages are formed and the heart still looks like it’s working normally and doing its job.This has been a life-long, constant, 24-7 job - to keep my heart clean and running. Just like the heart never rests, I never rest in babying it as best as I can. 


Between trying to keep my cholesterol as low as possible with whatever I can, following up with all the appointments, having a huge open-heart surgery at 40, where I had massive work done to clean out my sick arteries, replace my valve, replace my aorta, keeping my weight under control, learning as much as I can about FH and heart disease, learning to listen to all the symptoms, always fighting for the right care for me, switching doctors, traveling when needed, learning how to eat a clean diet, even when the whole world tells you that a diet won’t make a difference - all of these and more contribute to being here and living a full life, for me, at 49. This is so many more years beyond what my original prediction was when, at 8 years old when they diagnosed me with FH, the life expectancy that I was given was somewhere between 10 to 15 more years, at most. 


I am grateful for it all and most importantly for the thousands of people who constantly look for a cure. For the thousands of gutsy people who have FH and who participated in many clinical trials so we can get better drugs. And for some brilliant people that have been on my side. I have always felt like an experiment with this disease. And I am beyond the moon that the experiment has been successful thus far. I am also grateful that all my 4 caths have been planned procedures. I would hate to be wheeled into the cath lab in an emergency while having a heart attack. Things would look a lot different then, I am sure. And a lot of people out there find out what a cath is exactly like that.
