Congestive heart failure is a major cause of morbidity and mortality in the western world and is the leading cause of hospitalization in older patients. However, over one third of patients with decompensated heart failure have normal left ventricular systolic function (heart failure with normal ejection fraction (HFNEF)). This condition occurs when left ventricular filling and relaxation are impaired during the diastolic phase of the cardiac cycle. In this work, patients with HFNEF are imaged with MRI to measure the degree of aortic stiffness and diastolic dysfunction. The relationship between the resulting measurements is studied and compared to normal volunteers.
