HF can have numerous and diverse presentations on ECG screening. In general, the presence of left atrial enlargement and LV hypertrophy is sensitive (although nonspecific) for chronic LV dysfunction.
Two-dimensional echocardiography is recommended in the initial evaluation of patients with known or suspected HF and enables the evaluation of ventricular function. Primary and secondary valvular abnormalities may also be accurately assessed.
Endomyocardial biopsy is only indicated when a specific diagnosis is suspected that would influence therapy in patients presenting with HF.
BUN and creatinine levels can be within reference ranges in patients with mild-to-moderate HF and normal renal function, although BUN levels and BUN/creatinine ratios may be elevated. Renal function should be monitored in all patients with HF, as renal dysfunction contributes significantly to the morbidity and mortality associated with the disease.
