Question Answer
Heart failure
HF is result of
Causes of heart failure
Pathogenetic mechanisms of Heart Failure
Most common causes of Heart Failure
Compensatory mechanisms to maintain pumping function of the heart
Types of hypertrophy
Classification of Heart Failure
Causes of chronic left-sided failure
Left-sided heart failure causing:
Chronic left-sided heart failure (mechanisms of changes)
Chronic left-sided heart failure (morphological changes in the lungs)
Most common causes of acute left- sided failure
Acute left-sided failure (morphological changes) 1) acute congestion 2) Edema - fluid accumulating inalveolar lumen Alveoli filled with fluid and alveolar septa, capillaries are also filled with blood significantly
Chronic right-sided heart failure (causes)
Most common causes of right-sided heart failure ex. chronic bronchitis - mostly due to smoking
Chronic Right-sided heart failure cusing:
Acute right-sided heart failure (causes)
Total heart failure All the morphological features will appear, the heart will be enlarged and the cavities will be enlarged
Causes of arterial blood supply insufficiency
Arterial blood supply insufficiency (cause)
Compensatory mechanisms of arterial blood supply insufficiency
Compensation of dimnished arterial blood supply Increase amount of blood vessels , colaterals are connected and activated.
Infarction
Development of Infarction depends upon:
Morphology of infarction
Morphological changes in the area of infarction by time Granulation tissue --> 4-5 day (strts) Mature CT --> 20 days Scar --> after 2 months
Morphological chnges in the area of infarction Focal proliferation of CT in the damaged area The cells near the scar tissue will undergo hypertophy to compensate and restore the heart muscle function
Cerebral Infarction
Red infarction of lung
Insufficiency of local venous blood circulation
Insufficiency of local venous blood circulation (morphology)
Post-thrombotic syndrome
Insifficient lymph drainage
