Subarachnoid haemorrhage (SAH) is an uncommon type of stroke caused by bleeding into the space around the brain (the subarachnoid space, found between the arachnoid and pia mater).

SAH classically produces a thunderclap headache - patients report a sudden-onset headache that is the worst headache of their life.

SAH can be traumatic (the most common cause), caused by head injury, or be spontaneous, typically due to a ruptured berry aneurysm.

Subacute bacterial endocarditis (SBE) is a slowly-developing IE, typically caused by the Streptococcus species S. viridans.

SBE is an infection of the inner lining of the heart (the endocardium) and is associated with vegetations on heart valve surfaces with eventual valve destruction if the infection is not treated effectively.


Spontaneous coronary artery disease (SCAD) occurs when a tear appears in the wall of a coronary artery.

SCAD presents similarly to angina or a heart attack, and may cause an MI or even cardiac arrest.

SCAD typically affects young to middle-aged women, many of whom have no/few risk factors for CHD.
