Post-Partum (or
peripartumPeripartum cardiomyopathy) cardiomyopathy is a relatively rare form of heart failure that affects women during or following pregnancy. Establishing a diagnosis requires 1. The absence of a determinable cause for cardiac failure, 2. Absence of preexisting heart muscle disease, and 3. Time limitations of onset of illness from the last month of pregnancy to the first 5 post-partum months. Peripartum cardiomyopathy complicates 1 of 1300 to 4000 deliveries in the United States. This condition may affect women of any race, age, or number of prior deliveries; however, older, multigravida, African American and twin pregnancies are thought to represent predisposing features. The cause is unknown.
The treatment is standard heart failure medication (diuretics, digoxin, ACE inhibitors) and in severe cases heart transplant. Approximately half of patients with this diagnosis will return to normal within 6 months. Of those who do not return to normal the prognosis is poor with an average survival of 4.7 years after diagnosis (without transplant). Repeat pregnancies are not recommended for women who have had peripartum cardiomyopathy. You can find additional information in the following articles.

Surely Lucille, who has already regained some pump function, must have quite a favourable prognosis?
Myself, I wrote to you a year ago, absolutely terrified by the same diagnosis, and I was told that the poor prognosis (average survival 4,7 years) only concerned women who, in spite of medication, had obvious symtoms of heart failure. I have also searched your archives, and several times I have read that of those who does not return to normal, approx. 50 % deteriorates, but 50 % remain stable with mild to moderate symptoms of heart failure!
Dear Lucille,
I wish all the best for you and your little baby, and I hope that you will be able to enjoy your child in spite of your illness. I have had the same diagnosis myself, and now, a year later, I am strong and healthy again. I'll pray that this will happen to you, too.
Love,
Maria
Maria,
If possible, could you contact me in refernce to your comment on my posting. Also terrified by the diagnosis, would like to talk!

I was initially worked up for a transplant, luckily for me
Coreg came out. I take Coreg 25mg BID, Lanoxin 0.125 qd, Zestril 5 BID, and Bumex 2mg HS. I had an ejection fraction of less than
30 and I couldn't do anything. I was basically bedridden for about 2 years.
Things have improved. I don't want to bore you with details of all the tests, major heart centers I have been to, disasters that have resulted, but today, my EF is better, I go to cardiac
rehab 3X week and I have a life back.
I am by no means out of the woods here. I had to get a pacemaker in February, and I have had one problem after another, AND, now that I have found this site, I will be contacting Cleveland Clinic for a consult.
I am 45 years old, I have six kids. The cardiac rehab was, in my mind, the single most important thing, next to the drugs. The support, as well as the exercise and caring people in a similar boat, really keep me up, when its hard to see the forest from the trees.
BUT, as I said before, I AM STILL HERE!!!!
Don't listen to anyone that tells you 4.7 years-you can't worry about it- you could get hit by a bus tomorrow. Keep the faith.!
My mother is still fighting this illness after five years. You both have my prayers. You will live to see your sweet little baby grow up and have some babies. Keep your head up and always look at the good. keep a smile on your face!!
PPC is a hard condition to accept and fight, because it is so rare. My OB/GYN has been in practice for 20 years, and I was her first case! Support groups will help with the emotional upheaval, and if you are lucky to have a supportive family (I am) your life can return to normal -- or close. I still keep in mind everyday of my life that I have a heart condition and I still remember everyday that I can't have more children (that hurts so much!)but I do have everyday. My aunt is on a waiting list for a transplant...the doctors think that she had PPC, but her children are 30 and 32 years old. Who thought 32 years ago that women could have heart failure? Or that it would be linked to pregnancy. Fortunately for my husband and children, I am now relatively healthy, thanks to good doctors.
Now what I want know about is future pregnancy. Is it life threatning? What are the chances of having a normal pregnancy and delivery. If this occurs again, what are my chances of a similar recovery. One cardiologist mentioned if a woman has this and then waits 10 years the chances of recurrance is diminished. Is this true? I know that each case is different, but after going through several cardiologists in New Orleans, I cannot find anyone who is knowledgable on this topic. Maybe you could recomend someone in the New Orleans area

had a baby.. She is my third and is now 2months old.. I
started having problems with bradycardia, chest pains and other
symptoms.. Had an echocardiogram done, the results were negative.
Had a Holter monitor and that came back irregular.. I now go
in about a week for a Thallium stress test.. I don't know
what to expect.. This staying in limbo waiting to find out
if something is wrong is a hard place to be..
Take care of yourselves...
Unfortunately, this year (2000) Marg has developed a malignant and aggressive primary brain tumour, known as a gbm iv. Her outlook on life is still prayerful and cheerful. We have a web diary of her progress at: http://www.geocities.com/oldparl/journey.htm
for those who are interested. In her two linked talks she refers to the two cardiac episodes in 1986 and 1987.
Our prayers and best wishes to anyone who has been struck by PPCM. Denis Strangman, Canberra, Australia. ***@****
I was wondering, I had Postpartum myocardiomyopathy with CHF in February 1995 and in June of 1995 I was off all medications. What would be the percentage of this returning after 5 years? I don't plan on having anymore children, I was just curious. Thank You

German researchers have discovered that a drug commonly prescribed to new mothers to halt lactation also cures a rare type of heart failure known as postpartum cardiomyopathy (PPCM). The team made the discovery after accidentally designing an animal model that showed them exactly what caused the condition.
Denise Hilfiker-Kleiner from Hannover University and her team designed a genetic knockout mouse to study the function of an important transcription factor called Stat-3 (Signal transducers and activator of transcription 3), a protein that regulates cell proliferation. The modified mouse was missing the gene coding for Stat-3.
'We bred these mice and noticed that many of them did not survive multiple pregnancies. When we monitored them more closely, we discovered that this knockout was susceptible to this exact type of heart failure [PPCM] so we knew Stat-3 must be involved,' co-author Helmut Drexler told Chemistry World.
The group showed that PPCM is caused when prolactin, a hormone released at birth to stimulate lactation, is converted into a smaller, biologically active peptide known as 16kDa prolactin. This smaller, nastier version of the hormone destroys the endothelial lining of blood vessels and reduces blood flow to the heart. Stat-3 prevents prolactin from being cropped down into this destructive peptide.
The researchers confirmed this by treating the pregnant knockout mice with bromocriptine, a drug that inhibits the release of prolactin. 'In our mouse model bromocriptine completely prevented PPCM,' said Hilfiker-Kleiner.
Stat-3 increases the formation of antioxidant proteins, protecting the heart from oxidative stress. Without these antioxidants, stress on the heart cells leads to increased levels of the enzyme responsible for cleaving prolactin into its damaging counterpart.
PPCM is a very rare condition affecting one in every 1300 to 4000 deliveries in the US but, as Drexler emphasises, it leads to death in around a quarter of the women it affects and many of those who survive require a heart transplant. 'Since this affects a mother shortly after childbirth, it is especially traumatic,' he said.
Fortunately, Bromocriptine is an established drug that has been used for years to halt lactation in new mothers. So it can be used directly to treat women with PPCM or with high risk for PPCM, Hilfker-Kleiner told Chemistry World.
Bromocriptine has already been trialled in a small preliminary study in 12 women with a high risk of PPCM and was shown to prevent PPCM. 'This was a preliminary trial. We need to prove the effectiveness of our therapy in a larger randomised and blinded trial, before we can be sure that it really works.'
They have discovered that, in mice, PPCM is caused by a faulty prolactin gene. This gene produces a faulty version of the prolactin hormone, which damages the cardiac capillary network. Makes sense really that prolactin is involved when you consider that PPCM develops as the body starts to lactate.
They found that if they gave the mice Bromocriptine(an inhibitor of prolactin) they did not develop PPCM. Bromocriptine is the drug they used to give routinely to non breastfeeding mothers to 'dry up' their milk.
They tested this in a very small sample of women who had PPCM in a previous pregnancy and the ones taking bromocriptine did not develop PPCM the second time whereas most of the ones not taking it did develop PPCM again. They only tried this on small number of women (about 10 I think) so they need to do a trial with more people to prove it however it looks highly possible that they have found the cause and a way of preventing and possibly treating it.
. Here, we show that female mice with a cardiomyocyte-specific deletion of stat3 develop PPCM. In these mice, cardiac cathepsin D (CD) expression and activity is enhanced and associated with the generation of a cleaved antiangiogenic and proapoptotic 16 kDa form of the nursing hormone prolactin. Treatment with bromocriptine, an inhibitor of prolactin secretion, prevents the development of PPCM, whereas forced myocardial generation of 16 kDa prolactin impairs the cardiac capillary network and function, thereby recapitulating the cardiac phenotype of PPCM. Myocardial STAT3 protein levels are reduced and serum levels of activated CD and 16 kDa prolactin are elevated in PPCM patients. Thus, a biologically active derivative of the pregnancy hormone prolactin mediates PPCM, implying that inhibition of prolactin release may represent a novel therapeutic strategy for PPCM.
