Articles about drink causing heart disease (6)
I believe the answer is:
angina
'heart disease' is the definition.
(angina is a kind of heart disease)
'articles about drink' is the wordplay.
'articles' becomes 'ana' (a and an are indefinite articles).
'about' indicates putting letters inside.
'drink' becomes 'gin' (gin is a kind of drink**).
'ana' placed around 'gin' is 'ANGINA'.
'causing' is the link.
(Other definitions for angina that I've seen before include "Severe chest pain" , "Sudden cardiac pain" , "Severe pain from heart disease" , "Nag Ian about his disease" , "pain in the neck" .)
