Echocardiography Services Aurora Health Care No conflicts or off label use CP Heart Failure is A complex clinical syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with (diastolic) or eject blood (systolic) ESC guidelines for heart failure European Heart Journal 25 CP Emergence of New Epidemics of Cardiovascular Disease Two new epidemics of cardiovascular disease are emerging: Heart failure and atrial fibrillation. Hospital admissions for heart failure have climbed steadily, so that this condition has become the single most frequent cause of hospitalization in persons 65 years of age and older. CP Prevalence of CHF by Age NHANES II and III % Age (years) CP

2 CP Symptoms: Rest or exercise Systolic dysfunction Heart failure Structural abnormality Diastolic dysfunction High filling pressure The Burden of Systolic and Diastolic Ventricular Dysfunction in the Community Appreciating the Scope of the Heart Failure Epidemic JAMA, 23 Margaret M. Redfield, MD Steven J. Jacobsen, MD, PhD John C. Burnett, Jr., MD Douglas W. Mahoney, MS Kent R. Bailey, PhD Richard J. Rodeheffer, MD CP In the community, systolic dysfunction is frequently present in individuals without recognized CHF. Furthermore, diastolic dysfunction as rigorously defined by comprehensive Doppler techniques is common, often not accompanied by recognized CHF, and associated with marked increases in all-cause mortality.
