An otherwise healthy woman died suddenly after suffering chronic heart failure, an inquest heard.
Marceline Njokom-Fongwa, from Lucas Road in Sudbury, died at her home on April 18.
Last Thursday’s hearing into Mrs Njokom-Fongwa’s death heard that the 30-year-old, who was originally from Cameroon, had gone to bed at the normal time the night before she died.
“Her husband, Felix, had got into bed with her, but at 4am in the morning she woke up,” said Daniel Sharpstone, assistant coroner for Suffolk.
“She was breathing noisily and had white foam around her mouth.”
Mr Sharpstone said paramedics were called but were unable to resuscitate Mrs Njokom-Fongwa.
A post-mortem examination showed she had viral myocarditis, a disease which damages the heart muscles.
