P589Prognostic value of systemic immune-inflammation index in patients with chronic heart failure

severe symptomatic bradycardia or even life threatening asystole occurred which could be immediately interrupted by administration of Aminophyllin and Atropine.Remarkably, both patients with asystole showed a 1st degree AV-Block at baseline. Conclusion:In real world cardiology practice, appr.20% of the patients referred for ischemia testing cannot be adequately physically exercised.Regadenoson for pharmacological stress tests is in general well tolerated with frequent but harmless and transient side effects.Although very rare, life threatening asystole or severe bradycardia (0.08%) may occur but can be rapidly treated with Aminophyllin and Atropine.The official instructions for use mention that a 2nd degree AV-Block is a risk factor for the occurence of asystole.According to our experience, however, also patients with a preexisiting 1st degree AV-Block have an increased risk for developing a life threatening asystole, so the physicians should be aware of this and take precautions like having the antidotes ready and not removing the intravenous needle for 20 minutes after the injection.
