COR indicates Class of Recommendation; HF, heart failure; LOE, Level of Evidence; N/A, not available.
↵⁎ Although individual circumstances will vary, clinical stability is defined by the absence of low output, hypotension, persistent tachycardia, apparent shock, high-grade ventricular or symptomatic supraventricular tachyarrhythmias, and spontaneous recurrent ischemia.
