classification system of heart failure
NYHA
1st line and gold standard of HF
NT Pro-BNP
ECG
what does an FEV1:FVC ratio < 0.7 indicate
this indicates an obstructive picture
high curb-65 score treatment
IV co-amoxiclav and clarithromycin
most common bacteria for community aquired pneumonia
S.Pneumoniae
anaphylaxis pathophysiology
- Trigger that stimulates IgE production (1 mark)
- IgE stimulates mast cells (1 mark)
- To release histamine(1 mark)
- Degranulation (1 mark)
- This causes a rapid onset of symptoms, with airway, breathing and/or circulation
compromise (1 mark)
blood test for anaphylaxis
mast cell trypase
differentials of breast lump
- Cancer
- Fibroadenoma
- Breast Implant
- Hamartoma
- Breast Cyst
- Breast Abscess
- Lipoma
- Intra-mammary lymph node
- Ductal papilloma
- Fat necrosis

Increased risk of: breast/ cervical cancer
lowers risk of: ovarian/ endometrial
sensitivity
Sensitivity = Proportion of people with a disease that have a positive test result
specificity
Specificity = Proportion of people without the disease that have a negative test result
stroke acute treatment

scoring system to identify stroke
CHADVASc
first line treatment of stroke
DOAC
atheroscleorisis process
-
Endothelial Dysfunction. Injury to endothelial lining, caused by factors like
hypertension, smoking, high cholesterol. -
Lipid Accumulation. LDL cholesterol penetrates damaged endothelium. Accumulates
in subendothelial space. -
Foam Cell Formation. Monocytes transform into macrophages. Macrophages engulf
LDL, forming foam cells. -
Inflammation and Smooth Muscle Activation. Inflammatory response attracts
immune cells. Smooth muscle cells proliferate and migrate. -
Plaque Formation. Smooth muscle cells deposit collagen, forming fibrous cap.
Calcium deposits contribute to plaque hardening. -
Plaque Rupture and Thrombosis. Fibrous cap weakens, leading to plaque rupture.
Thrombus formation causes artery occlusion and clinical manifestations.
