Cardiovascular Disease in Birds of Prey

Area of Science:

• Avian medicine
• Veterinary cardiology
• Wildlife health

Background:

• Cardiovascular diseases (CVD) are frequently observed in both wild and captive raptors.
• Captive raptors face elevated risks for CVD due to altered lifestyles and diets.
• Existing research highlights a need for evidence-based treatment protocols and effective dosages for managing diagnosed cardiovascular conditions in raptors.

Purpose of the Study:

• To review the prevalence and risk factors of cardiovascular diseases in raptors.
• To discuss common cardiovascular conditions observed in raptors, including atherosclerosis, cardiomyopathy, and myocarditis.
• To explore current treatment strategies and identify gaps in knowledge regarding cardiovascular disease management in these avian species.

Main Methods:

• Literature review of cardiovascular diseases in wild and captive raptors.
• Analysis of risk factors such as dyslipidemia, inactivity, and age-related changes.
• Examination of secondary causes including infections and toxicities (e.g., lead poisoning).

Main Results:

• Atherosclerosis, often linked to dyslipidemia and inactivity, can lead to severe outcomes like sudden death or myocardial infarction.
• Other noted conditions include cardiomyopathy, arrhythmias, myocarditis, and endocarditis, frequently secondary to infections or toxins.
• Current treatment approaches are limited, primarily relying on supportive care, dietary modifications, and the off-label administration of cardiovascular medications.

Conclusions:

• Cardiovascular diseases pose a significant health concern for raptors, with captive populations being particularly vulnerable.
• Effective management strategies are hampered by limited research on optimal drug dosages and treatment protocols.
• Further investigation is crucial to improve the diagnosis and treatment of cardiovascular conditions in raptors, enhancing their welfare and conservation.
