Trastornos por cocaína e infarto agudo de miocardio,prolongación de estancias y exceso de costes hospitalarios

Introduction and objectives

To investigate the relationship between the prevalence of cocaine use disorders and acute myocardial infarction in patients aged ≥ 18 years and to estimate the influence of cocaine use disorders on mortality, excess length of stay, and overexpenditure among hospitalized patients with acute myocardial infarction.

Methods

Retrospective study of the minimum basic data set of 87 Spanish hospitals from 2008 to 2010.

Results

Among 5 575 325 admissions reviewed, there were 24 126 patients with cocaine use disorders and 79 076 cases of acute myocardial infarction. The incidence of acute myocardial infarction among patients with cocaine use disorders increased with age and reached a peak at 55 years to 64 years (P < .0001). Multivariate analysis showed that cocaine use disorders were more prevalent among patients with acute myocardial infarction independently of age, sex, other addictive disorders, and 30 other comorbidities (odds ratio = 3.0). Among patients with acute myocardial infarction, those with cocaine use disorders did not show an increase of in-hospital death, but did show excess length of hospital stay (1.5 days) and overexpenditure (382 euros).

Conclusions

Cocaine use disorders are associated with acute myocardial infarction and increase the length of hospital stay and overexpenditure among acute myocardial infarction patients. Cessation of cocaine use among these patients should be one of the primary therapeutic goals after hospital discharge.Full English text available from:www.revespcardiol.org/en
