Side Effects of Adriamycin, Herceptin, Other Breast Cancer Drugs May Increase Heart Risks: Study
Cardiovascular experts warn that some breast cancer treatments, including Adriamycin (doxorubicin), Herceptin and radiation treatment, may damage the heart, increasing the risk of fatal heart problems among breast cancer survivors.
The American Heart Association (AHA) issued a Scientific Statement on February 1, warning about the risk of heart damage from breast cancer treatments, and advising doctors to carefully monitor their effects on the heart.
The statement is an overview of the association’s current knowledge of breast cancer treatment and heart risks, and was also published in the medical journal Circulation.

Philips DreamStation, CPAP and BiPAP machines sold in recent years may pose a risk of cancer, lung damage and other injuries.
Learn MoreThe association notes that a number of recent studies have highlighted potential heart damage caused by breast cancer treatments, as well as an increased risk of death due to cardiovascular problems among breast cancer survivors.
One of the drugs, Adriamycin, and other doxorubicin-based medications used in chemotherapy can result in damage to heart cells, the AHA warns. Studies have indicated that the risk can be mitigated by administering Adriamycin slowly over time, instead of all at once. There are also signs that a drug called dexrazoxane could reduce cell damage among patients who receive high doses of Adriamycin and similar drugs, and has recently been approved for use in patients with metastatic breast cancer who have been receiving doxorubicin during chemotherapy.
The statement also notes that HER-2 targeted breast cancer treatments like Herceptin, can weaken heart muscle, resulting in heart failure. This is temporary in some cases, and function can return over time. However, in some cases it can lead to permanent heart failure. The group called for doctors to watch for signs of heart muscle weakening and to slow down or alter treatment if that occurs.
In addition to drug risks, radiation treatment can also cause problems with arteries, the statement notes. resulting in coronary artery disease or blockages.
“Any patient who is going to undergo breast cancer treatment, whether they have heart disease at the beginning or not, should be aware of the potential effects of the treatments on their heart,” Dr. Laxmi Mehta, chair of the writing group for the scientific statement, said. “This should not deter or scare patients from undergoing breast cancer treatment, but should allow them to make informed decisions with their doctor on the best cancer treatment for them.”
The American Heart Association indicates that there are about three million breast cancer survivors in the United States, and there are about 47.8 million women nationwide living with heart disease.

I’m one of the blessed ones who survived to tell my story.

I too suffer from Adriamycin chemotherapy. (HORRIBLE SIDE EFFECTS) HEART, LUNGS, STOMACH PROBLEMS. I read it has been discontinued use in the U. S. Is there a class action lawsuit against the maker of this horrible stuff?

Are these treatments killing me or saving me?

I too had Adriamycin/Cytoxin combo for breast cancer in 2005/2006. After Chemo I kept have heart issues & was told we have no idea what is wrong.

Does anyone want to firm a group and go after Pfizer the drug company! I heard they knew about it causing Heart Failure & I was never warned about this side effect. Its ruined my life. Not fair. We need to go after the Drug Company.

I'm only 65 and I'm in congestive heart failure. I've always led a healthy lifestyle. My adricimin drug in the chemo has rendered my life horrible. I hate this. I wish there was a lawsuit against st the makers of this drug.

I was given adriamycin for breast cancer in 2011. I now have leukemia. Where can I find a lawyer to sue them.

I was her+ had 6 rounds of taxotere, carboplatin, herceptin and perjeta. Then double mastectomy. Continued herceptin and perjeta for total of 11 months. My ejection fraction lowered from 55% to 36%. On the eleventh month. Still no improvement and this started Jan 2018

I received Adriamycin for breast cancer in 2012, along with radiation, emphasis on left breast. Then in 2013 was diagnosed with congestive heart failure. In 2019 my heart failure progressed to my ejection fraction going from 43% to15/20%currently. Currently going through review for an LVAD surgery, other wise medication treatment and earlier death.

I had breast cancer in 2005, was treated with chemo drugs including Adriamycin. I went into heart failure and had to have a heart transplant. I was told from the biopsy of my old heard that it was caused by Adriamycin. Such a long and hard road I went down. I was never told about the heart risks with the Adriamycin.

I was given the chemo drug Doxorubicin for breast cancer in 2015. I was never told of the risks to my heart. I was never monitored for my heart at all .

Are there really enough known benefits to keep experimenting with human lives???

My wife was just diagnosed with cardiomyopathy 4 years post treatment for breast cancer and radiation. TAC was "dose densed" for stage 2 breast cancer (one lymph node with cancer). She was also on tamoxifen for 4+ years. We showed up in the ER two weeks ago after 4 days of shortness of breath, fatigue and pain in the abdominal area.

TAC was "dose densed" for stage 2 breast cancer (one lymph node with cancer). She was also on tamoxifen for 4+ years. We showed up in the ER two weeks ago after 4 days of shortness of breath, fatigue and pain in the abdominal area. Nausea and diarrhea led us to believe maybe it was food poisoning or a hernia. Long story short: her heart was almost two times larger than normal ,she was throwing pulmonary embolisms into the lungs from clots found in the leg, and her heart ejection was 1/3 of normal. In other words, she was in advanced heart failure and close to dying. The immediate causality given was heart damage done by adriamycin and radiation. Clots may have been attributed to tamoxifen. Her heart was fine pre cancer treatment and now we're talking a possible heart transplant to keep her alive. No one warned us about these risks and she never received heart monitoring post chemo/radiation. I feel like the supposed "cure" for cancer may well be the thing that cuts her life short. She's only 54 years old. Please INSIST that you are closely monitored for heart damage if taking adriamycin and do not dose dense! My heart is breaking and I cannot stand to see her suffering now. It is a nightmare! God Bless you all.

I have cardiomyopathy thanks to my chemo treatments also. There should be a class action suit. I was NEVER informed of any possible side effects of this kind!!!
CatherineMarch 21, 2019 at 5:21 am
I have CHF as a result of Adriamycin cancer treatments and would like to know if there are any class action law suits

Heart failure, 70 yr old female diagnosed with breast cancer 2007 and adriamycin/cytoxin used to combat cancer. Is there class action on side effects of these drugs?
SuzanMay 17, 2018 at 4:40 pm
I have congestive heart failure from Adriamycin. Not fixable. Quality of life low. Many other problems associated with it.
