Newly diagnosed obstructive HCM: seeking advice and reassurance

Posted by MS @mshcm, Sep 17 10:16am

Hello everyone,

I was diagnosed with obstructive hypertrophic cardiomyopathy in November 2025, at the age of 51, following a severe pulmonary infection. Before this episode, the condition had been completely silent, and I had lived a normal and active life without knowing that I had it. I have no known family history of HCM or sudden cardiac death.

At the time of diagnosis, I had significant obstruction, with an LVOT gradient of approximately 115 mmHg. I have now been taking mavacamten and verapamil for about six months. My response to treatment has been very encouraging: the obstruction is now almost absent at rest, and my gradient with exercise has fallen below 30 mmHg.

My recent echocardiogram and ECG were very reassuring. My latest 48-hour Holter monitor was also excellent, with no concerning rhythm disturbances. I am able to live normally, exercise, and have very few symptoms, apart from occasional fatigue.

Despite these positive results, I still struggle emotionally with the diagnosis. Because the disease is new to me, I often worry about sudden cardiac death, future complications, whether the obstruction could return, and whether the condition could progress even while I am doing well. I have two children whom I love more than anything, and the fear of leaving them can sometimes become overwhelming.

I would be very grateful to hear from people with a similar experience:

• Has anyone had a very high gradient that became minimal with mavacamten?

• Did your condition remain stable over time with treatment?

• Were you able to return to a normal and active life?

• If medication controlled the obstruction well, did your doctors recommend continuing treatment rather than undergoing a septal myectomy?

• How did you learn to manage the anxiety and fear associated with HCM?

I understand that every case is different and that only my cardiologist can assess my personal risk. I am mainly looking for shared experiences, reassurance, and support from people who understand what it feels like to receive this diagnosis.

Thank you very much for reading and for sharing your experiences.

@whidbey je ne veux pas être indiscrète mais est ce que tes jumeaux ont hérité de la maladie ? Car mon fils de 18 ans se dirige actuellement vers une carrière de footballeur professionnel je n ai pas encore fait les examens pour déterminer si il a cette maladie ou non mais j ai très peur de cela …

@mshcm both of my twins are negative so far, but when the gene testing expands, I hope they will pursue the gene testing as well.

Thank you for sharing your experience and asking specific questions. I wasn’t diagnosed until I was 70. It was like a alarm went off on my 70th birthday. I was climbing a mountain in Colorado and had a kind of burning sensation in my chest that didn’t go away for several days I ended up going to a cardiologist after I went to see my primary doctor and she referred me. They told me I I had hypertropic obstructive cardiac myopathy. I started taking small amounts of metoprolol and I moved to sea level from 8000 feet. I still continued to have symptoms and then CAMZYOS became available. I started taking it almost 2 years ago and shortly after i started I was diagnosed with uterine cancer and went through a hysterectomy and radiation. The radiation really raised my obstruction. It was up to 143 and then consistently at 123. Through ladt fall, I was only taking five mg of CAMZYOS. With my cardiologist’s recommendation I managed to get it up to 10 mh taking five in the morning and five at night and continued with the Metropol 25 MG in the morning and 25 at night…. my last Eco this Aug was normal! I don’t have any symptoms of shortness of breath when climbing stairs, etc., that I had before. Previously, I would get pain going up steep Hills or climbing stairs, now I don’t. I am now 79 and feel very grateful for CAMZYOS . I used to enjoy drinking wine and I had to completely stop drinking alcohol five years ago because it was interacting with the Metropol and then it’s not recommended with CAMZYOS which is probably just as well since now alcohol has been exposed as a primary cause of cancer. I don’t think you have to worry about sudden cardiac arrest. You have really great results with CAMZYOS and you just have to keep taking it the rest of your life and of course it interacts with a lot of things. I had a mocktail with grapefruit juice in it, not realizing there was grapefruit juice in it, and I had a real scare that night, but nothing happened. I check every supplement or medication with my specialist pharmacy because of all the interactions. I haven’t had any visits to the hospital, and the cancer is gone as far as I know so I’m right now i on a teaching tour in Europe and I do seem to get tired easily, but I am traveling and teaching five hours a day so that is understandable. I’m coming to terms with the fact that I actually need to modulate what I do because I’m almost 80! But other than that i feel great. By mistake we rented a fourth floor walk up in Denmark and I really thought I don’t know if I can do this, but I just did two stairs and then paused, caught my breath and ended the next two and I managed it!

@joanallione I am in my second month of Camzyos.
I’m 84 so I needed an hour afternoon nap anyway, but this drug is making me very tired . Some dsts I don’t want to get dressed at all so I’m encouraged to know that that passes and that this will be the answer for me because I am still quite active.

I was diagnosed with HOCM at 64 yrs old. I thought I was just getting old and out of shape when I started huffing and puffing on walks and trying to walk up stairs. My primary care doctor noticed a heart murmur and referred me to a cardiologist. 2 years later I am on a beta blocker but have not been able to get approved for Camzyos. My LVOT gradient has risen to 178. My current cardiologist is retiring and I will be looking for a new one. I totally understand your feelings and I too have periods where I feel utterly helpless and kind of depressed but I think about my father who had it and he lived a pretty normal life until age 91 when he died of bladder cancer.

I was diagnosed with HCM at 54 yrs old and now 63. Was told as child I had a heart murmur but that never stopped me from having a very active and production life. In my late 40's I began to have issues with my blood pressure spiking and was placed on various medications which never helped much. Later, while deployed to the DMV (DC, Maryland, Virginia) area I went into a small University health clinic in Maryland for blood pressure and shortness of breath and they found my HCM. Shortly after, I was working in Texas and had to be admitted to a hospital due to shortness of breath and high bp. They verified my HCM diagnosis and I

I have been on Camzyos about 3 years now and it started out GREAT, unfortunately in 2025 my heart condition became worse. My murmur returned and my heart stopped after I became overwhelmed by heat exhaustion. Thankfully, I survived.

I am still taking Camzyos but had to undergo surgery for an ICD in November 2025, which I was told when first diagnosed surgery could be in my future. After some complications, I know feel better than ever. Still taking it easy because of my Type 2 diabetes diagnosis my healing process is slower than usual.

I became a little depressed during my recovery process and the change in lifestyle, but prayer helped me tremendously. 🙂

@mshcm so far my twins do not have HCOM. They will continue being tested every five years.

I am also in my 50's. I experienced some concerns in my late 30's, but I was diagnosed with a murmur and MVP. I was diagnosed about 8 years ago with HOCM. No one really clarified much with me, and camzyos was still really new. I moved to another state for a job, and I did not care for my cardiologist. I finally got one that I trust about 2 years ago. I started on camzyos in April. I had an ICD implanted in May. The results are a small improvement, but not nearly what they should be. I am scheduled at Mayo for a septal myectomy in November. The anxiety is real, and it is okay for you to spend time processing it. I think for some people it might be helpful to process this with a counselor that works with people with chronic illnesses or maybe a clergy person...
I do think it is normal to have these feelings. It is a lot to deal with. Be kind to yourself, and do the things that bring you joy. Don't let the anxiety steal all your living. You have a lot of that to do! Praying prayers of peace for you.

@thoma175 I'm 80 now. I was diagnosed accidentally at 65. I had a septal myectomy at Mayo 15 years ago. There's been serious improvements since then. Now they fix the mitral valve while they're in there. I wish they had that option back then. But, luckily, they can fix the mitral valve noninvasively now. I'm doing fine. I have a good quality of life. I, too, had some less than satisfactory experiences with cardiologists. So, in my opinion, that's a very critical problem that has to be fixed. I've had unexpected retirements of great cardios, was on the hunt again, and am in good shape again today. So, for those fearing a shorter lifespan because of HOCM or HCM, I'm living proof that being your own advocate and maintaining quality medical care can result in longevity and good quality of life. Stay informed. I used to feel afraid about its impact on my life. Not anymore.

@cpaddyo We "met" in a different discussion earlier and I am glad you are at Mayo and yes, it is the Gold Standard treatment. I was 75 when I had a septal myectomy, so very glad I did, the surgery is 99+% successful at Mayo. I traveled from Upstate NY to there on referral from my doctor. Like you, my HCM worsened and surgery was necessary.

There are good discussions about septal myectomies, here are 2: https://connect.mayoclinic.org/discussion/what-i-learned-from-my-open-heart-surgery-part-1/ and https://connect.mayoclinic.org/discussion/my-septal-myectomy-decision-and-10-things-ive-learned-since/

Verapamil in high doses created an uncomfortable problem for me that Metamucil, exercise, much water and fiber did not help, hope that is not your experience! Keep us posted on this journey. When is you next appointment?

@walkinggirl Thank you for your valuable insight regarding oHCM.
I was diagnosed with obstructive HCM in May after 2 recent cardiac episodes and many years of sporadic symptoms . After the first episode (in February) the hospital cardiologists told me I had Takotsubo syndrome because they observed a severe ballooning of the left ventricle during the echo. I explained that I did not have a recent severe physical or emotional stress situation, the cause of Takotsubo syndrome, but they maintained their diagnosis and sent me home after 3 days. The 2nd time was in early May with much more severe symptoms. 3 days in cardiac ICU + 2 days in observation. The cardiologist, realizing that it was not Takotsubo, suggested the genetic test and cardiac MRI. The test came back positive for HCM.
I am now under the care of the director of the HCM center in NYC. The stress test performed at the center did not reveal any obstruction although I performed at 130 % of the average. I then had a cardiac catheterization with a chemical IV which demonstrated severe obstruction and ballooning of the left ventricle, apparently a very rare occurrence in HCM patients, hence the cardiologists’ confusion.
First I was prescribed Metoprolol which strongly exacerbated my hair loss. Then the HCM specialist switched to Bisoprolol (a very low dose because I do not have constant obstruction ) but I still had palpitations and shortness of breath. I was then prescribed Disopyramide in addition to Bisoprolol, and also Pyridostigmine to counteract the nefarious side effects of Disopyramide. Well, that was not well tolerated at all by my digestive system so I was taken off those 2 medications. The HCM specialist is now trying to get me approved for a new medication called Aficamten, FDA approved only in January 2026. But he is leaning towards septal myectomy and mitrial valve repair as being the best solution. I admit that I am terrified at the idea of the open heart surgery. Is the recovery excruciatingly painful and lengthy?
I apologize for the long post. I thought providing background would be helpful.

@dp80 votre message est extrêmement rassurant, mon cardiologiste m’a dit plusieurs fois que la HCMO n avait pas d incidence sur l espérance de vie … mais je ne voulais pas l entendre car pour moi c était associé justement au contraire 😨… merci d avoir partagé votre expérience je vous souhaite vraiment de continuer à vous rétablir et à vous sentir de mieux en mieux !

I inherited OHCM and I have it with similar results you have very encouraging for the last 3 years. Therefore, relax for this is great with no side effects and I have a normal life now at 66 years old and I am still slowly jogging and when I can I sprint fast enough as a 35 year old person. So take it easy, enjoy life and do not worry at all. God keeps blessing you.
