Left Ventricular Cardiac Index with Angio Blood Pressure (Calculated Index)

What This Test Measures

The test calculates a ratio (index) of blood flow through your left ventricle relative to your blood pressure. Blood flow is often derived from echocardiogram or cardiac catheterization data, while blood pressure is measured directly. This index reflects how effectively your heart pumps blood to supply oxygen and nutrients to your body.

Why It’s Done

Doctors may order this test if you have symptoms like fatigue, shortness of breath, or swelling that could indicate heart problems. It’s also used in patients with known heart conditions, such as heart failure or coronary artery disease, to monitor heart performance and guide treatment decisions.

Common Conditions Monitored

This calculated index is particularly useful for diagnosing or monitoring conditions like congestive heart failure, where the heart’s pumping ability may be impaired. It can also help assess heart function in patients with valvular heart disease or after heart surgeries.

How the Test Works

The test combines measurements from two sources: blood flow through the left ventricle (often measured via ultrasound or catheterization) and your blood pressure. A mathematical formula converts these values into a single index that reflects overall heart efficiency. No blood sample is drawn for this specific calculation.
