38. regressive changes in the heart muscle and their pathological appearance. Myocarditis

Question 1

regressive changes in heart muscle

Answer 1

hydropic degeneration
fatty infiltration
fatty degeneration
lipofuscinosis
myofibrillar degeneration
mineralization
myocardial necrosis

Question 2

cause of myocardial necrosis

Answer 2

nutritional deficiencies
toxicities
physical injuries and shock
infections
myocardial infarct

Question 3

toxicities causing myocardial necrosis

Answer 3

ionpohores
vit d
calcinogenic
t2 mycotoxin
uraemia

Question 4

myocardial necrosis

Answer 4

focal, multifocal, diffuse
pale, dry
+/- gritty
outcome is either acute or chronic cardiac failure

Question 5

healing of myocardial necrosis

Answer 5

by fibrosis

Question 6

hydropic degeneration

Answer 6

due to
antineoplastic drugs
antiretroviral drugs
autointoxication

Question 7

fatty infiltration

Answer 7

between the cardiac muscle fibres

Question 8

fatty degeneration

Answer 8

in the sarcoplasma
due to anaemia and toxemia

Question 9

lipofuscinosis

Answer 9

brown atrophy, accumulation of debris
due to ageing and cachexia

Question 10

myofibrillar degeneration

Answer 10

aka myocytolysis
furazolidon toxicity in plants

Question 11

mineralization

Answer 11

due to
vit e deficiency
vit d toxicity
calcinogenic plants

Question 12

myocarditis cause

Answer 12

infections spread hematogenously to the myocardium
inflammation can spread from endo/peri cardium

Question 13

lesions of myocarditis

Answer 13

pale areads
abscess or phlegmone in suppurative myocarditis
