Hi I'm here because I don't think there's many active cavy forums. I am in the USA. I have 2 boys I adopted from an animal shelter in bad shape, and then another set of boys who were found abandoned in a box in October. I took them in, and recently one was diagnosed with congestive heart failure. Looking for people who have experienced CHF in guinea pigs. Right now he is taking orbax, furosemide, metacam, and theophylline. I took him to the vet a week ago because I thought he was breathing awfully hard for a pig. He also has a cough. We took xrays and he has a ton of fluid in his lungs - the xrays look like his left lung is pretty much full of fluid, and the right lung is maybe 25% full. He is doing well on the meds despite the vet thinking we should put him down. He is acting relatively normal - eating, pestering his brother, begging for food - but I can't say his breathing has improved. We have a follow up visit on Wednesday. As they were abandoned and I've had them just shy of a month, we have no clue on their real age or past history.
Hi and welcome
I have personally never had a piggy with congestive heart failure but several of our forum members have had heart piggies. With the only one of mine that had a build up of fluid in the chest cavity (it is either this or the lungs where the fluid collects but never both), the suspicion was rather something pressing on the heart (a tumour or lymphoma). The heart itself was perfectly fine on the scan and the lungs were clear. Unfortunately the actual problem was hidden behind the dazzle of the fluid; and an explorative operation was not an option.
Forum members with chronic heart piggies have generally made good experiences with having vetmedin added in addition to furosemide by their vets. Vetmedin is a heart drug used for dogs. Perhaps something you would like to discuss with your vet?
Furosemide is a crucial heart drug; it is a diuretic that causes increased peeing in order to drain any build-up of fluid; it is also used in human heart treatment. In the UK you can find sometimes frusol being prescribed; it is furosemide in a syrup to make it easier to medicate than the fraction of a tablet.
Theophylline is not a drug that I have seen used in guinea pigs before but it is specifically targeting the lungs so I assume that your vet is using it to address the congestion in the lungs and to ease the breathing as much as possible. One of its possible side effectsis also increased urination.
Orbax is a cat antibiotic for urinary tract infections; again it has been likely prescribed to increase the urination.
Metacam is an analgesic (painkiller and anti-inflammatory)
Like with humans living with heart failure, it very much depends on how well he is responding to the drugs and whether you can buy him enough quality of life. This area in guinea pigs is sadly under-represented in veterinary medicine; it is not long since I have seen general vets who believed that there was actually no such thing as heart problems in guinea pigs.
I am keeping my fingers firmly crossed for your boy! Great that he has found such a loving and committed home.
