Abstract

Simple Summary Feline cardiomyopathy (FCM) is a serious, potentially fatal disease in cats. There is an international screening program that aims to identify pedigree cats affected with FCM, as the disease is believed to be inherited in some cat families. Using a self-reporting questionnaire, this study explored the long-term outcomes of cats breed-screened for FCM. We found that approximately 9.3% of the cats developed FCM at some time-point of which approximately 50% were diagnosed within the screening program and 50% of these cats at the first breed-screen occasion. For cats that did develop FCM, there was a significantly higher risk for a cardiac related death and also a shorter time to all-cause mortality, compared to cats that did not develop FCM. Frequency and types of non-cardiac disease were similar in all screen classification groups. The large proportion of cats that did develop FCM later in life, despite normal previous screen results, underscores the value of repeated breed-screenings later in life to identify cats that develop FCM. Feline cardiomyopathy (FCM) is an important contributor to feline morbidity and mortality. This explorative follow-up questionnaire study was aimed at investigating the long-term outcome in cats breed-screened for FCM (BS-FCM) in three Nordic countries. Records of cats with >= 1 BS-FCM between 2004-2015 were included. Of the 1113 included cats, 104/1113 (9.3%) had developed FCM at some time-point. Fifty-nine of the 104 (56.7%) FCM cats were diagnosed within the screening program (Screen(FCM)), and 33/59 (55.9%) of these were diagnosed at the first BS-FCM. Screen(FCM) cats or with an owner-reported FCM diagnosis at a later time-point had a higher risk of cardiac-related death compared to cats that never developed FCM. A shorter lifespan was found in Screen(FCM) cats compared to those with normal screen results (p < 0.001). Times to all-cause mortality were shorter (p < 0.001) in cats that developed FCM at any time-point compared to those that did not. Non-cardiac morbidities were similar in all screen classification groups. The large proportion of cats that developed FCM at a later time-point underscores the need for repeated screenings later in life. Cats that developed FCM at any time-point had a shorter lifespan, with a similar proportion and in line with the nature of non-cardiac morbidities, compared to those without FCM.
