AMI
blood flow to the heart is cut off due to a blockage in the coronary artery
Bronchiectasis;
irreversible dilation of the bronchi due to structural airway injury.
CF:
caused my mutations to the CFTR gene. Causing abnormalities to salt and fluid clearance across the epithelium
Lobar pneumonia;
inflammatory exudate within the alveolar space
Pleural effusion;
excess fluid in the pleural space
Pneumothorax;
air in the pleural space between the visceral and parietal pleura
Chronic bronchitis;
expectoration (sputum) on most days for 3/12 for 2 years
emphysema
enlargement of air spaces and destruction of alveolar walls
bronchopneumonia
inflammation of the bronchi and lungs
ILD
lung disorder that produces similar inflammatory and fibrotic changes in the interstitum or intra-alveolar septa of the lung
pathology of emphysema
Thin atrophied airway walls, and loss of alveolar walls and capillary beds
pathology of chronic bronchitis
Mucous gland hypertrophy & goblet cell hyperplasia → ↑ mucus production.
Ciliary dysfunction → impaired clearance of mucus.
Chronic inflammation in small airways →
* Narrowing of lumen
* Cellular infiltrates (inflammatory cells),
* Oedema of airway walls.
pathology of pneumothorax
Loss of negative intrapleural pressure causes the lung to collapse inwards.
Pathology of pleural effusion
Fluid compresses the lung underneath and restricts expansion.
pathology of lobar pneumonia
Alveolar spaces are filled partially or completely with fluid and blood cells (infectious debris & exudate)
Pathology of CF
Defective CFTR protein causes impaired chloride secretion and increased sodium absorption.
Leads to dehydrated, thick mucus on epithelial surfaces.
Lungs’ airway obstruction leads to infections, inflammation and bronchiectasis.
pathology of bronchiectasis
Loss of cilia, mucous gland hyperplasia, airway wall destruction, and permanent dilation of the bronchi
pathology of ILD
Inflammation and fibrosis develops in the interstitial and alveolar tissues.
This makes the lungs stiffer (↓ compliance) → harder to expand with each breath.
The alveolar–capillary membrane thickens, impairing diffusion of gases, especially oxygen.
pathology of bronchopneumonia
Alveolar spaces are filled partially or completely with fluid and blood cells (infectious debris & exudate)
pathology of AMI
describe the differences in presentation between a person with angina vs myocardial infarction
ANGINA:
- Chest pain that’s triggered by exercise and stress
- pain eases with rest
-temporary decreased blood flow
- no permanent heart damage
MYOCARDIAL INFACTION:
- chest pain is more severe and long-lasting
- pain doesn’t go away
- leads to permanent damage (death of the heart muscle)
What does NSTEMI stand for
Non-ST elevation myocardial infarction
What STEMI stand for
ST Elevated myocardial infarction
What is STEMI
complete artery blockage causing necrosis, characterized by elevated Troponins
