Thank you to Katie Sullivan for presenting the case of an elderly woman with history of type 1 diabetes and CAD s/p CABG presenting after colonoscopy with severe nausea/vomiting and diarrhea. The patient was found to be in DKA likely 2/2 to an NSTEMI with EKG changes suggestive of ischemia and a troponin of 25!
- Complications after colonoscopy are rare (approximately 3 per 1000 screening colonoscopies) and include complications of sedation, complications related to the preparation, bleeding, and perforation.
- Never forget that Ischemia – acute MI – can precipitate DKA!! See the rest of the “I’s” below brought to you by our wonderful interns Noa and Hayley.
- Any patient with ACS regardless of intervention (stent or no stent) should be treated with DAPT for 12 months b/c of improved cardiovascular outcome. Bleeding risk needs to be balanced against benefits and shorter durations are sometimes used. (See graph from the study)
- Troponin elevation in the setting on non-ACS related demand is associated with worse f/u cardiac mortality in both low and high risk patients. In one study incidence of cardiovascular death or heart failure after adjusting for conventional risk factors (hazard ratio 1.84, 95% CI 1.30-2.61) .
- Patient with the flu are at a much higher risk of ACS during and in the week after illness. A recent Canadian study in the NEJM showed that MI admissions were 6x more likely to occur in the week after a positive flu test!!
Remember the I’s for causes of DKA reviewed!!
- In-adherence to medications
- (I)Other: hypercortisol and sympathetic surge
- Prognostic value of cardiac troponin I measured with a highly sensitive assay in patients with stable coronary artery disease.
