Brief Summary
Recently literature revealed facts, that show H+/K+ ATPase expression is not limited tot he stomach. H+/K+ ATPase was also found in smooth muscle cells and in other tissues (McCabe, R.D. et al., Am J Physiol. 1992). For myocard a localisation is only proven for rats yet (Beisvag, V. et al., Acta Physiol Scand. 2003). Moreover biochemical hints lead us to a highly probability of a myocardial H+/K+ ATPase (Nagashima, R. et al., Jpn Heart J. 1999).

Outcome Measures
Primary Outcomes (1)
Aim of our clinical study is to examine, whether proton pump inhibitors have an influence on myocardial contraction of human myocard and we want to ascertain the amount of influence of a H+/K+ ATPase on myocardial contraction.

- Only patients with a left ventricular ejection fraction as demanded in the study protocol
- Only patients with clinical symptoms of congestive heart failure, corresponding to New York Heart Association stage NYHA II or III
- Only patients without oral or i.v. application of a proton pump inhibitor up to 48 hours prior to the study catheterization
You may not qualify if:
- Manifest or severe accompanying diseases, despite of diabetes mellitus
- Intravascular or oral application of proton pump inhibitors within the last 48 hours
- Intake of Metformin within the last 24 hours
- Status post heart transplant
