RESECTION OF THE ATRIAL APPENDAGES AND ITS IMPACT IN THE NATRIURETIC HOMEOSTASIS: DEVELOPMENT AND VALIDATION OF AN ANIMAL MODEL IN AN ACADEMIC MEDICAL CENTER.

Background: The left atrial appendage (LAAp) resection is an effective treatment approach to reduce the risk of thromboembolism in patients with atrial fibrillation.

Objective: To study was to study the impact of removing atrial appendages in the production of natriuretic peptides (NPs) in conditions of volume overload and to develop an experimental model of LAAp resection.

Materials And Methods: In a swine model of ischemic heart failure (HF), serum NP levels were measured before (Basal-1A) and after (Basal-1B) a fluid overload.

[Hyperglycemia controlled with GIK solution in non-diabetic patients subjected to heart surgery].

Unlabelled: We prospectively compared, the glucose-insulin-potassium (GIK) solution 1,000 mL 10% glucose, 20 units of fast acting insulin and 60 mEq of potassium chloride, against a GIK solution with 1,000 mL of glucose, 40 units of fast acting insulin an 120 mEq of chloride, in the hyperglycemic control of non-diabetic patient subjected to cardiac surgery. We divided 40 patients in four groups ten patients each. Group A was the control they received 1,000 mL of 10% glucose in water, 20 units of fast acting insulin and 60 mEq of potassium chloride in a drops/ hour dose without an infusion pump.
