Heart Failure
Heart failure, sometimes known as Congestive Heart Failure (CHF), occurs when the heart can't pump enough to the rest of the body. If the heart muscle cannot pump enough blood, it cannot meet the body's needs for blood and oxygen. The heart is a pump that circulates the blood throughout the body.
Lung Nodules
A lung nodule, also called a pulmonary nodule, is one of the most common abnormalities seen on radiographic images, and is a small mass of tissue in the lung that is smaller than 3 cm (slightly more than an inch) in diameter. The nodule appears as a white shadow on a chest X-ray or computerized tomography (CT) scan.
