Outcomes of Patients With Cocaine Induced Chest Pain in An Inner City Hospital

Abstract

Background: Cocaine induced chest pain is a major reason for admission in Safety Net Hospitals in the United States. The majority of patients admitted undergo extensive work-up leading to enormous economic burden. We hypothesize that in individuals with low risk, cocaine does not further increase adverse cardiovascular outcomes.

Methods: We conducted a retrospective chart review of all patients admitted with chest pain to our hospital between 07/01/09 and 06/30/10. We excluded patients with modifiable risk factors for coronary artery disease (CAD). The study population was divided into cocaine and non-cocaine group based on urine drug screen. We analyzed data including demographic, laboratory, cardiac testing, detection of CAD, length of stay and mortality rates.

Results: A total of 426 individuals matched our inclusion and exclusion criteria and were considered to have no known modifiable cardiac risk factors; 54 in cocaine group and 372 in non-cocaine group. Based on physician discretion, 41(76%) in the cocaine group and 239(64%) in the non-cocaine group underwent various modalities of cardiac testing. Cardiac testing was positive in 6(2.5%) patients in non-cocaine group and none in the cocaine group (p=0.597). There was no significant difference between length of stay and in-hospital mortality between the two groups.

Conclusions: In individuals at low risk for CAD, cocaine use resulted in higher rate of cardiac testing. However, there is no difference in prevalence of CAD and in-hospital mortality between the two groups. We conclude that cocaine does not increase adverse outcomes in patients with low risk for CAD.
