Heart Ultrasound by Emergency Medicine Residents as an Estimate of Heart Function

The Guthrie Clinic17 enrolled

Overview

The purpose of this research is to better understand the use of heart ultrasounds to estimate heart function.

This research involves ultrasounds of the heart by two different emergency medicine doctors who are residents in training. Results from the two doctors will be compared to see how similar they are. This research will help us understand if heart ultrasounds can be used to see how well the heart pumps blood and if similar results are obtained from different doctors. The doctors will use ultrasound of the heart to measure E-Point Septal Separation (EPSS). EPSS is the distance between two parts of the heart, the mitral valve and the ventricular septum. EPSS is measured in millimeters (mm). EPSS can estimate left ventricular ejection fraction (LVEF) as a measure of how well the heart pumps blood.

Outcomes

Primary Outcomes

Mean change in millimeters between E-Point Septal Separation (EPSS) measurements of the heart by two physicians

Two physicians will use the same ultrasound device to measure the E-Point Septal Separation (EPSS) on the same patients. EPSS is the distance between two parts of the heart, the mitral valve and the ventricular septum. The mean change in EPSS measurements in millimeter will be calculated.

Time frame: During procedure

Secondary Outcomes

Percent change in Left Ventricular Ejection Fraction (LVEF) estimated from ultrasound compared to a formal transthoracic echocardiogram.

Percent change in Left Ventricular Ejection Fraction (LVEF) estimated from ultrasound compared to a formal transthoracic echocardiogram. LVEF (in %) will be estimated from ultrasound using the formula = 75.5 - (2.5 x E-Point Septal Separation in millimeters)

Time frame: During procedure
