Is a drug-challenge test with propafenone adequate to exclude Brugada syndrome?

Brugada syndrome is associated with sudden cardiac death in patients with a structurally normal heart. The electrocardiogram (ECG) pattern of Brugada syndrome is characterised by complete or incomplete right bundle branch block and ST-segment elevation in the right precordial leads. These ECG signs may not always be apparent but can be unmasked with certain anti-arrhythmia agents.

Acute myocardial infarction elevates serine protease activity in saliva of patients with periodontitis.

Background And Objective: There are indications that acute myocardial infarction (AMI) may have an effect on the oral environment, which is reflected in the expression of salivary and gingival proteinases. According to our knowledge, no studies have been carried out to investigate the effect of AMI on the activities of two major tissue-destructive serine protease and microbial effectors, elastase and cathepsin G, produced by oral fluid polymorphonuclear granulocytes (PMN). Therefore, we compared the activities of elastase and cathepsin G in saliva from patients with AMI and from systemically healthy subjects (non-AMI) with similar periodontal conditions.
