Evidence of primary hypertrophic or restrictive cardiomyopathy, or systemic illness known to be associated with infiltrative heart disease; - Known right heart failure by pulmonary or pulmonary vascular disease not related to the left heart; - Pericardial constriction; - Restrictive or obstructive pulmonary disease, as evidenced by the requirement for home oxygen; - End-stage renal disease currently requiring dialysis; - Bi-ventricular pacemaker (CRT-P + ICD); - Acute coronary syndrome.
