In addition to heart failure tests — which may include blood tests, X-rays and an echocardiogram — John C. Lincoln's health care providers use a clinical assessment of each patient. Listening carefully to what our patients tell us is an invaluable part of the diagnosis process.

The two key components of the initial patient assessment are the medical history and physical examination. To gather this information, our nurses typically start by interviewing the patient about his or her risk profile, history of cardiac events and response to previous medical therapies.

Vital questions, such as those listed below, help our health care providers develop a diagnosis.
