ObjectiveTo study the trends of arrhythmia hospitalizations with cannabis use disorders (CUDs) in terms of demographic characteristics and inpatient outcomes.MethodsWe used the nationwide inpatient sample (NIS) data during the post-legalization period (2010-2014) and included 570,556 arrhythmia inpatients (age, 15-54 years), and 14,426 inpatients had comorbid CUD (2.53%). We used the linear-by-linear association test and independent-sample T-test for assessing the change in hospital outcomes in inpatients with CUD.ResultsArrhythmia hospitalizations with CUD increased by 31% (2010-2014). This increasing trend was seen in adults (45-54 years, P < 0.001) and was predominant in males (77.6%). Hypertension (40.6%), hyperlipidemia (17.6%), and obesity (15%) were prevalent medical comorbidities with variable trends over the five years. Among substance use disorders, tobacco (50.9%), and alcohol (31.4%) were major comorbidities with a variable trend (P = 0.003 for each). There was a 71.4% increase in the inpatient mortality rate between 2010 (0.7%) and 2014 (1.2%). The mean length of stay was three days, and the total hospitalization charges have been increasing (P < 0.001), averaging $35,812 per hospital admission.ConclusionChronic cannabis use or abuse worsens hospitalization outcomes in arrhythmic patients, and more clinical studies are needed to study the causal association between these conditions due to the rising mortality risk.
The aim of this study was to observe the trends of intractable vomiting and cannabis use disorder (CUD) with demographic characteristics, medical and psychiatric comorbidities, and hospitalization outcomes. Methods We conducted a retrospective cohort study using the nationwide inpatient sample (2010 to 2014). Patients aged 16-50 years discharged with a primary diagnosis of intractable vomiting and CUD were included (N = 9,601). We used the linear-by-linear association chi-square test and independent-sample T-test for measuring the categorical and continuous data, respectively.
Regadenoson is a pharmacological stress agent that has been widely used since its approval by the Food and Drug Administration (FDA) in 2008. For many years, dipyridamole and adenosine, which are non-selective adenosine receptor agonists, were more popular. However, these agents are less preferred now due to their undesirable adverse effects as compared to regadenoson. In the ADVANCE (ADenoscan Versus regAdenosoN Comparative Evaluation) phase 3 clinical trial, regadenoson demonstrated non-inferiority to adenosine for detecting reversible myocardial ischemia. This review summarizes the clinical utilities of regadenoson as the most widely used pharmacological stress agent. Moreover, the use of regadenoson has been documented in specific patient populations. Although regadenoson has established safety and efficacy in most patients with chronic diseases, there are equivocal results in the literature for other chronic diseases. It is warranted to highlight that the use of regadenoson has not been studied in patients of low socioeconomic class; it is a condition that carries a significant burden on the cardiovascular system.
Background and Objectives: Recent observations indicate that cannabis use can result in cardiovascular complications including arrhythmias. We studied the relationship between cannabis use disorder (CUD) and arrhythmia hospitalization. Methods: We conducted a retrospective analysis of the Nationwide Inpatient Sample (2010-2014). Patients (age 15-54) with a primary diagnosis for arrhythmia (N = 570,556) were compared with non-arrhythmia (N = 67,662,082) inpatients for odds ratio (OR) of CUD by the logistic regression model, adjusted for demographics and comorbid risk factors.
Wellens' syndrome, also regarded as left anterior descending coronary T-wave syndrome, is an electrocardiography (EKG) pattern that indicates critical proximal left anterior descending artery (LAD) stenosis. It is characterized by deeply inverted T-waves or biphasic T-waves in the anterior precordial chest leads in a patient with unstable angina. Patients typically present with symptoms consistent with acute coronary syndrome. We present a unique case of Wellens' syndrome with no angiographic findings of significant stenosis in the proximal LAD but with significant occlusion of the proximal circumflex artery and initial presentation with a chief complaint of epigastric pain and syncope. Physicians need to recognize these characteristic EKG changes during the pre-infarction stage, as they represent myocardial necrosis. Many of these patients eventually develop extensive anterior myocardial infarction with marked left ventricular dysfunction and death if coronary angiography and coronary revascularization are not performed within a few weeks. If Wellens' is seen, patients should undergo urgent cardiac catheterization.
