An observational study in Hypovolemia, Heart Failure and Diastolic Dysfunction, sponsored by Umeå University. Completed at 1 site in Sweden. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2022-01-05.
Sponsored by Umeå University · Observational
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.
122 studies on the registry are indexed under Hypovolemia; 14 are open to participants now.
This study's enrollment of 100 is above the median of 51 across 58 observational studies indexed under Hypovolemia.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Ran from Dec 2017 to primary completion in Nov 2018, 11 months.
Of 25 observational studies under Hypovolemia, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 30. This study's 11 months is below that.
