View clinical trials related to Cardiac Output, Low.
Filter by:This is a prospective, randomized, non-blinded, single-center efficacy study of acutely decompensated heart failure patients with reduced ejection fraction (HFrEF), low cardiac index (<2.2) as determined by pulmonary artery catheter (PAC) who have been hemodynamically stabilized and ready for transition to oral vasodilator therapy at the discretion of the clinician. The investigators would like to accomplish the following objectives with this study: 1. Establish the superiority of an upfront initiation strategy for sacubitril-valsartan at maintaining patients on ARNI therapy at one-month follow-up compared to usual care. 2. Establish the safety of initiating sacubitril-valsartan in an intensive care setting 3. Characterize the hemodynamic effect of sacubitril-valsartan on patients with low cardiac output 4. Expand the population of hospitalized patients that can be initiated on ARNIs and thus facilitate prior to hospital discharge patients who are on optimal goal-directed medical therapy (GDMT) for heart failure
On the Intensive Care Unit doctors give a lot of fluid to patients in order to improve their blood pressure, amount of urine made or to let doctors stop drugs that are needed to keep blood pressure up. Doctors normally give patients 500ml of fluid over 25 minutes as standard, however it is very difficult to know if giving those fluids and how much fluid will help (it does in some but not others). If a person gets too much fluid this can also cause problems such as fluid in lungs, poor kidney function, or swelling in the limbs. The LidCo Rapid monitor lets the Intensive Care Unit (ICU) team know the amount of blood the heart pushes out with each beat (Stroke volume). It works by following the tracing off the arterial line (Blood pressure monitor) that has been inserted as part of the standard care of a patient on the ICU. It does not need any other invasive procedures or drug administration to work. This study is using this monitor to see if it can identify a method of improving the administration of intravenous fluids on the Intensive Care Unit. The study is looking to see if it can identify whether giving a small amount of fluid first identifies people who will benefit from more fluid and those that won't.
Each year in the United States more than 30,000 children are admitted to intensive care units. The majority of these children have some degree of heart instability during their stay, yet there is currently no routine way to measure the actual amount of blood that the heart pumps. The ability to measure the amount of blood that the heart pumps accurately and easily at frequent intervals would be very helpful to the doctor caring for these children because many of them have poor heart function as a result of their illnesses. Current techniques used in adults to measure output of the heart are either not readily transferred to children or demand difficult invasive procedures. Because of this, the amount of blood that the heart pumps cannot be measured with enough frequency to help guide care. Despite this reality, accurate measurements of the amount of blood that the heart pumps in these patients at crucial points in their illnesses would allow for more accurate use of potentially harmful procedures and could possibly improve the outlook for these children. Likewise, being able to correctly measure blood volume could provide a better way to estimate the pressure on the heart and improve treatment. The purpose of this research study is to compare the accuracy of doctor estimates of heart output, and establish the usefulness of central blood volume measurements by PCOM (pediatric cardiac output measurements), a less invasive procedure
