Novel Single Wave Assessment in Measuring Cardiac Dysfunction and Metabolic Syndrome in Patients With Cancer

This clinical trial studies a novel single wave assessment in measuring cardiac dysfunction and metabolic syndrome in patients with cancer. The novel single wave assessment is a hand held device that can report left ventricular ejection fraction, which measures how well the heart is pumping blood (by giving a percentage) and measures how stiff the arteries are in the heart (pulse wave velocity). A novel single wave assessment may help identify patients at increased risk for type II diabetes and metabolic syndrome (disease where patients have increased blood pressure and high blood sugar level and excess body fat around the waist and abnormal cholesterol levels).

Inclusion Criteria: * Adult patients undergoing 2D echocardiogram at City of Hope (COH) * Patients with a current or past diagnosis of cancer * Ability to sign a written informed consent Exclusion Criteria: * Inability to provide informed consent * Patients who have known "carotid sinus hypersensitivity" * Patients who do not consent to blood draw * Patients who have not fasted for the instructed time prior to blood draw
