Phase IV Study of a Feasible Insulin Algorithm for Glycemic Control in Patients With Acute Coronary Syndrome

The proposed study is a one center open-label randomized controlled clinical trial.Coronary Intensive Care of one hospital in the city of Curitiba, PR, Brazil will be assessed.

Consenting eligible subjects will be randomized to either the intensive insulin infusion therapy group (ITG) or the conventional therapy group (CTG).

The control group will be selected following the same set of inclusion and exclusion criteria. Patients will be randomized to receive SC regular insulin 4 times daily (before meals and bedtime) or every 6 hours if they are NPO .

Data will be collected for history of diabetes, heart disease ; hypertension; hyperlipidemia; Current smoker; Cardiac treatment (Aspirin, Beta Blockers, ACE inhibitor/A2RB, Nitrates, Statin, Fibrate) Diabetes treatment(Insulin, Metformin, Sulphonylureas) Data will be collect for Baseline BGL , A1C level, Troponin, CPK, CKP-Mb, K, Creatinine. Classify Infarct type : Anterior/anteroseptal, Inferior, Non-ST-segment elevation myocardial infarction, Not classified Cardiac intervention : PTCA , Thrombolysis,No reperfusion, Heparin or low-molecular weight heparin.
