Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

The restoration of coronary flow after transient ischemia immediately induces life-threatening ventricular tachyarrhythmias. Although most of these arrhythmias disappear spontaneously, some of them induce serious hemodynamic changes. This retrospective study investigates the efficacy of therapy with intracoronary verapamil to terminate reperfusion-induced ventricular tachyarrhythmias in patients with acute myocardial infarction (AMI).', 'Between February 1992 and February 2003, 390 patients with a diagnosis of AMI were enrolled into the study. All patients received mechanical revascularization therapy within 6 h of onset of symptoms, and 109 patients experienced reperfusion-induced tachyarrhythmias. A subset of these patients was treated with intracoronary verapamil (0.25 to 1.0 mg) to terminate the reperfusion-induced tachyarrhythmia. They were evaluated for immediate termination of the tachyarrhythmias, hemodynamic changes, resumption rates, and major complications. Thirty-one patients (28%) were treated with intracoronary verapamil for the immediate termination of reperfusion-induced ventricular tachyarrhythmias. These tachyarrhythmias included 6 premature ventricular contractions, 19 accelerated idioventricular rhythms, 3 ventricular tachycardias, 2 ventricular fibrillations (VFs), and 1 torsades de pointes. Intracoronary verapamil was effective in rapidly terminating all reperfusion-induced arrhythmias except for VFs. The side effects of treatment included temporary hypotension (two patients) and bradycardia (one patient), although all patients recovered spontaneously. No major complications were induced by the intracoronary use of verapamil, and no resumptions of arrhythmias were documented.

Anxiety disorders increase risk of future cardiovascular disease (CVD) and mortality, even after controlling for confounds including smoking, lifestyle, and socioeconomic status, and irrespective of a history of medical disorders. While impaired vagal function, indicated by reductions in heart rate variability (HRV), may be one mechanism linking anxiety disorders to CVD, prior studies have reported inconsistent findings highlighting the need for meta-analysis.', 'Studies comparing resting-state HRV recordings in patients with an anxiety disorder as a primary diagnosis and healthy controls were considered for meta-analysis.', "Meta-analyses were based on 36 articles, including 2086 patients with an anxiety disorder and 2294 controls. Overall, anxiety disorders were characterized by lower HRV [high frequency (HF): Hedges' g\u2009=\u2009-0.29. 95% CI: -0.41 to -0.17, p\u2009<\u20090.001; time domain: Hedges' g\u2009=\u2009-0.45, 95% CI: -0.57 to -0.33, p\u2009<\u20090.001] than controls. Panic disorder (n\u2009=\u2009447), post-traumatic stress disorder (n\u2009=\u2009192), generalized anxiety disorder (n\u2009=\u200968), and social anxiety disorder (n\u2009=\u200990), but not obsessive-compulsive disorder (n\u2009=\u200940), displayed reductions in HF HRV relative to controls (all ps\u2009<\u20090.001).

Duodenal stump disruption remains one of the most dreadful postgastrectomy complications, posing an overwhelming therapeutic challenge.', 'The present report describes the extremely rare occurrence of a delayed duodenal stump disruption following total gastrectomy with Roux-en-Y esophagojejunostomy for cancer, because of mechanical obstruction of the distal jejunum resulting in increased backpressure on afferent limp and duodenal stump. Surgical management included repair of distal jejunum obstruction, mobilization and re-stapling of the duodenum at the level of its intact second part and retrograde decompressing tube duodenostomy through the proximal jejunum.
