Wisnieski Heartworm Research Published
Lincoln Memorial University-Richard A. Gillespie College of Veterinary Medicine (LMU-CVM) Associate Professor of Public Health and Research Lauren Wisnieski, PhD, has a new paper published in “Frontiers of Veterinary Science” revealing a lack of preventative use for heartworm.
Less than 40% of dogs in the longitudinal Golden Retriever Lifetime Study were on preventative heartworm medications at baseline. This is a troubling discovery, as heartworm disease is a serious and potentially fatal condition that is preventable in dogs.
This study, funded by Morris Animal Foundation, investigated what factors predict heartworm preventive medication use in the golden retrievers in the Study cohort. The team unearthed critical factors associated with a reduced likelihood of dogs being on heartworm prevention, including dogs in the highest quartile of height, sexually intact dogs and dogs receiving supplements. Conversely, dogs receiving other vaccines or diagnosed with an infectious disease or an ear, nose, or throat health condition during their health checkups in the last year were likelier to receive heartworm preventives.
Wisnieski, the study’s principal investigator, emphasized the scarcity of studies examining the prevalence of prophylactic use in dogs. She said this recent project is especially crucial as climate change has extended mosquito season in certain states, making year-round vigilance imperative.
Despite advances in understanding heartworm disease, including improved diagnostic tests and safer, more effective treatments, heartworm disease remains a significant health threat for pets in all 50 states.
Heartworms can grow to a foot long and cause lasting damage to the heart, lungs and other organs. While treatment is possible, it can be financially costly for the owners and often means a long recovery, if successful, for the pet.
“This data can help inform how veterinarians talk to clients,” Wisnieski said. “It can also help identify populations that have risks of nonadherence. Prevention is a cheaper alternative to the financial burden of treating heartworm disease later.”
Wisnieski said now that she and her team have preliminary data, they will work on broadening their research scope. This expansion will encompass diverse dog breeds, those given supplements, the impact of cost on preventative use and the effect of the human-animal bond.
