Early reperfusion is the treatment of choice for acute coronary syndrome. In the Czech Republic, reperfusion therapy is well accessible thanks to the network of 22 catheterization centres. ⋯ These steps than has to be accompanied by effective pharmacotherapy to prevent remodelling of the left ventricle, re-stenosis of the coronary artery, re-thrombosis and arrhythmias. Four drug groups provide the desired effects--renin-angiotensin-aldosterone system blockers, beta-blockers, antiplatelet agents and statins.

Review[Pathophysiological background for incretin therapy: is it capable of more than we think?].
Incretin-based therapy functions through the increase of endogenous glucagon-like peptide-1 (GLP-1) levels due to inhibition of dipeptidyl peptidase-4--an enzyme degrading GLP-1 (gliptins) or through the administration of drugs activating GLP-1 receptor (GLP-1 agonists). Both approaches increase insulin and decrease glucagon secretion leading to improved diabetes compensation. The advantages of gliptins include little side effects, body weight neutrality and potential protective effects on pancreatic beta cells. ⋯ Direct positive effects of incretin-based therapy on myocardial metabolism and function as well as its positive influence on endothelial dysfunction and neuroprotective effects are intensively studied. The possible indications for GLP-1 agonists could be in future further widened to obese patients with type 1 diabetes and obese patients without diabetes. The aim of this review is to summarize both metabolic and extrapancreatic effects of incretin-based therapies and to outline perspectives of potential wider use of this treatment approach.
