Resumo
UNASSIGNED
Marijuana use has been increasingly legalized in the United States resulting in substantial rise in the number of users especially in the younger populations. While our group and others had described various metabolic effects of this drug, little is known about its association with acute myocardial infarction.
UNASSIGNED
To present a series of 8 patients with 10 events of ST-elevation MI (STEMI) associated with marijuana use; highlighting their demographic, clinical presentation, laboratory results and angiographic characteristics.
UNASSIGNED
Retrospective chart review of patients with STEMI presenting to our inner city hospital Coronary Care Unit over a period of 4 years (December 2013-April 2017).
UNASSIGNED
Of the 10 case subjects studied who presented with chest pain, EKG evidence of STEMI with cannabis use, mean age at presentation was 40.1 ± 9.7 (years) SD, ranging from 26 to 59 years old. There were 9 males and one female, of them, 8 were Black, 2 Hispanic and 1 White. Of the 10 cases, 3 (30%) had no known cardiovascular disease (CVD) risk factors (RF) on admission, 1 patient had 3 RF, 4 patients had 2 RF and 2 had 1 CVD RF, which included age, diabetes mellitus type 2 (DM2), hypertension, dyslipidemia, smoking, and family history of premature coronary heart disease. Troponin I (cTnI) peak mean level was 93.5 ± 34.35 ng/ml, range 7.86 - 358.0 ng/ml. All patients had angiographic evidence of obstructive coronary angiography.
UNASSIGNED
In our study, marijuana use is associated with ST-elevation MI in largely minority population, occurring at a relatively younger age with half of the cases either low risk or CVD risk free. Additional studies are needed to further characterize this population given the increase in marijuana use.
