Overview
Exercise stress testing with an assessment of oxygen consumption is useful in assessing the functional capacity of the heart failure patient, angiography can exclude the presence of an ischemic basis for the disease, cardiac catheterization can evaluate hemodynamic basis of heart failure and the response to drug, and myocardial viability studies can determine whether hypocontractile myocardium is viable but just hibernating, and could therefore benefit from revascularization.
Exercise Stress Testing
Exercise stress testing is useful in measuring the "functional capacity" of heart failure patients. It is also helpful to assess the efficacy of congestive heart failure treatment.
Myocardial Viability Studies
Myocardial viability studies can determine whether hypocontractile myocardium is viable but just hibernating, and could therefore benefit from revascularization. Common imaging modalities to assess myocardial viability include:
- Dobutamine echocardiography
- Nuclear tests (SPECT or PET)
- Cardiac MRI
Cardiac Catheterization
Coronary Angiography
Coronary angiography is perfomred in patients with heart failure in whom there is a suspicion of underlying atherosclerosis as the basis for the heart failure. Patients who are troponin or CK-MB positive, who have dynamic EKG changes or other signs and symptoms of an acute coronary syndrome who are revascularization candidates should undergo coronary angiography.
Hemodynamic Assessment
right heart catheterization for assessment of pulmonary artery resistance.
