Acute myocardial infarction (AMI) and in-hospital mortality rates following Carbon monoxide (CO) poisoning have not been studied in a national database.
All hospitalized patients age ≥18 years included in the nationwide inpatient sample (NIS) 2002–2010 databases with a confirmed diagnosis of CO poisoning, as per the ICD-9-CM code 986 were identified. Discharge weight was used to predict national estimates. MV logistic regression analysis was used to determine the association of incident AMI and in-hospital mortality as well as to identify independent predictors of incident AMI among hospitalized CO-poisoned patients.
Patients hospitalized with CO-poisoning (n=19,949) had a mean age of 51 (±18) years, 40% were women, and 74% Whites. Incident AMI during the same hospitalization occurred in 1,119 (6%) of 19,949 CO poisoned patients. In-hospital mortality occurred in 9% (98/1,119) of incident AMI patients compared to 3% (50/18.830) of non-AMI patients (adjusted odds ratio, 2.50; 95% confidence interval, 1.93–3.24; P < .001). Among the 98 AMI patients who died in the hospital, 31% had a cardiac arrest, 26% had an anoxic brain injury; and 10% had both cardiac arrest and anoxic brain injury. Independent predictors of incident AMI among CO poisoned patients are displayed in the Table.
In this national database, AMI was uncommon after hospitalization due to CO poisoning; however, AMI was an independent predictor of in-hospital mortality.
