3rd degree AV blockWhat tends to be the presentation of lyme carditis?False (it may be the cause, but it isn't well understood)True or false: if a dog presents with 3rd degree AV block and they test positive on Lyme titers, then Lyme is the causeTrypanosoma cruziWhat is the causative agent of Chagas disease?Reduvidae bugWhat is the vector for Trypanosoma cruzi?TX, Mexico, South and Central AmericaWhere in the world is Trypanosomiasis more common?Severe myocarditis, RA and RV affected, RCHFWhat are the effects of Trypanosomiasis on the heart?Benznidazole must be requested from CDC, may not improve cardiac outcomeWhat is special about the treatment for Trypanosomiasis myocarditis?Toxoplasma gondiiWhat is the causative agent of Toxoplasmosis?Other system signs predominate, necrotizing myocarditis possible, cardiac disease rarely evident clinicallyWhat are the characteristics of Toxoplasmosis infection on the heart?Dogs, CatsIn what species can necrotizing myocarditis occur as a result of Toxoplasmosis?Toxoplasma, LeishmaniaWhat are 2 possible causes of protozoan myocarditis?Leishmania chagasiWhat is the causative agent of Leishmaniasis?Lymphoplasmacytic myocarditis, myocardial necrosis and granulomasWhat cardiac lesions can occur in dogs with Leishmania?Suspected heritable, nutritional deficiency, myocardial toxic agents, physical injury or shock, myocardial disease with systemic diseaseWhat are some examples of non-infectious acquired myocardial disease?TrueTrue or false: in lab animals, there are different lines of animals that can be bred for particular forms of heart diseaseGlycogen storage disease, Duchene's Muscular dystophy, hereditary CM in turkeys, spontaneously hypertensive rats, HCM, DCMWhat are some examples of suspected heritable diseases that cause myocarditis?False (may manifest later in life)True or false: heritable cardiomyopathies only occur early in lifeSelenium and Vit E deficiencyWhat is the cause of white muscle disease?Cu deficiency in cattle, Thiamine deficiency causes high CO heart failure, taurine deficiency in cats, Se overdose causes cardiotoxicity in horsesWhat are some examples of nutritional imbalances that lead to myocardial disease?DoxorubicinWhat is a drug that is used in chemotherapy that can cause cardiotoxicity?Oxidant injuryHow does doxorubicin cause cardiotoxicity?DCM like syndrome, arrhythmiasWhat is the presentation of doxorubicin cardiotoxicity?240mg/m2What is the cumulative maximum lifetime dose that can be given of doxorubicin?Predisposed to DCMWhat dogs should doxorubicin be used cautiously in for chemotherapy?False (dogs more sensitive)True or false: cats are just as sensitive to doxorubicin cardiotoxicity as dogsCatecholamine cardiotoxicity, defibrillationWhat is a possible cause of this finding?Results in hypertension, myocardial necrosis, pericarditis with uremiaHow can renal failure affect the heart?Heart, eyes, kidneys, brainWhat organs are targeted for damage in systemic hypertension?LVH, possible proximal aortic enlargementWhat are the results of systemic hypertension on the heart?Retinal hemorrhage, detachmentWhat are the results of systemic hypertension on the eyes?Glomerulosclerosis, progressive renal failureWhat are the results of systemic hypertension on the kidneys?Hypertensive encephalopathy, CNS stroke, hemorrhageWhat are the results of systemic hypertension on the brain?False (can be caused by hypertension, but may also be a normal aging change)True or false: a torturous aorta, as seen on this radiograph, is diagnostic of hypertensionPheochromocytomaWhat is a functional tumor secreting catecholamines?Tachycardia, systemic hypertension, esp episodic, collapse, episodic signsWhat are the signs associated with a pheochromocytoma?Catecholamines released in pulsesWhat are signs episodic in pheochromocytoma?TrueTrue or false: a pheochromocytoma is more likely to grow into the CVC and obstruct flow than an adrenal carcinomaTrueTrue or false: stimulating specific areas of the brain has been shown to create specific arrhythmias, which is a possible explanation for Brain Heart Syndrome with a CNS lesionVentricular arrhythmiasWhat type of arrhythmia is associated with shock, especially in dogs?False (must be monitored, if fast enough tachycardia or repetitive enough)True or false: shock or myocardial injury that causes ventricular arrhythmias always requires antiarrhythmicOlder, large breedWhat dogs with shock are more likely to get ventricular arrhythmias?TrueTrue or false: ventricular arrhythmias can occur in horses with some acute abdominal diseases, like strangulating or inflammatory lesionsFalse (true in humans, limited association in vet species)True or false: there is a close association between heart disease and diabetes mellitus in both humans and animalsAdenomaWhat is the most common cause of hyperthyroidism in cats?CarcinomaWhat is the most common type of thyroid tumor in dogs?Usually nonfunctional, very vascular, difficult to resectWhat are the characteristics of thyroid carcinomas in dogs?Usually function, hyperthyroid, treated with methimazole, radioactive iodine, or surgeryWhat are the characteristics of thyroid adenomas in cats?PU/PD, Polyphagia, tachycardia, increased CO, LVH, sometimes CHF or arrhythmiasWhat are the signs of feline hyperthyroidism?False (only a small number will get CHF, most have a little cardiac change but not enough to cause CHF)True or false: most cats get CHF as a result of hyperthyroidism putting additional stress on the heartParrots, dogs with severe hypothyroidismWhat animals may be at risk of getting atherosclerosis?
