A name, “Ms Lollobrigida”, may result in problem of the heart! (6)
I believe the answer is:
angina
'heart' is the definition.
(thesaurus)
'a name' is the wordplay.
'a' becomes 'an'.
'name' becomes 'gina' ().
'an'+'gina'='ANGINA'
'ms lollobrigida may result in problem of the' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for angina that I've seen before include "heartfelt complaint?" , "Heart ailment" , "chest complaint" , "Sudden cardiac pain" , "Nag Ian about his disease" .)
