Prevalence of Hypovolemia and Heart Failure in Non-cardiac Surgery

Prevalence of Hypovolemia and Heart Failure in Non-cardiac Surgery

Prevalence of biventricular function of the heart and preoperative level of venous return is not known in non-cardiac non-morbid obese population.

The aim of the study is to assess the preoperative function of the heart and status of hypovolemia on the day of surgery.

Preoperative transthoracic echocardiography (TTE) is conducted in 100 individuals. Biventricular function (i.e. systolic and diastolic properties), left ventricular filling pressures and level of venous return are assessed by TTE.

Moreover high-sensitive troponine I and Nt-proBNP, ECG are collected. Multiple echocardiographic parameters will be studied for feasibility in terms of preoperative assessment of the heart.

Inclusion Criteria:

• body mass index ≤ 35 kg/m2, electively scheduled for breast cancer surgery, endocrinologic surgery (thyroid, parathyroid) and general abdominal surgery.

Exclusion Criteria:

• Not signed consent.
