An unusual precipitant of acute heart failure-ANCA-associated vasculitis in a patient with ischaemic cardiomyopathy: a case report.

Antineutrophil cytoplasmic antibody-related pulmonary renal vasculitis can lead to rapidly progressing renal failure and may present as ADHF in a patient with existent CAD. The associated VT storm in our patient can be attributed to hyperkalaemia secondary to acute renal failure. A multidisciplinary approach is required for the successful management of such a complex clinical scenario.
