==Noninvasive assessment of pulse wave amplitude ratio==
Once the diagnosis of heart failure is made, subsequent laboratory studies should be directed toward the identification of an underlying cause of heart failure.
Laboratory Tests
Renal Function
Renal function should be assessed as a rough guide to the patient's intravascular volume status and renal perfusion. A urinalysis is helpful in the assessment of the patient's volume status. Electrolyte assessment and the correction of electrolyte disturbances such as hypokalemia, hyperkalemia and hypomagnesemia is critical in those patients treated with diuretics. Hyponatremia (due to poor stimulation of the baroreceptors and appropriate ADH release and free water retention) is associated with a poor prognosis.
Hematologic Studies
A complete blood count should be obtained to assess for the presence of anemia which may exacerbate heart failure and to assess the patients coagulation status which may be impaired due to hepatic congestion.
Thyroid Studies
The assessment of thyroid function tests is particularly important in the patient who is being treated with concomitant therapy with an agent such as amiodarone.
Biomarkers
Biomarkers are going to play a great role in diagnosis of heart failure.
Natriuretic Peptides: BNP or NT-proBNP
BNP or its amino-terminal cleavage equivalent (NT-proBNP) is generated by cardiomyocytes in the context of numerous triggers, most notably myocardial stretch.
BNP levels may be useful in the initial establishment of the diagnosis of heart failure in the patient with dyspnea of unclear etiology. In a meta-analysis, BNP was superior N-terminal pro-BNP (NTproBNP) and was associated with a sensitivity of 85% and specificity of 84% in the diagnosis of heart failure in the primary care setting.[1]
These biomarkers have been studied for the detection of elevated cardiac pressures[2][3][4], low ejection fraction[5], or both[6][7].
Clinical practice guidelines suggest their measurement is helpful for diagnosis or ruling out heart failure especially in acute setting.[8]

heart failure, BNP: B-type natriuretic peptide, COR: Class of Recommendation, ED: emergency department, HF: heart failure, NT-proBNP: N-terminal pro-B-type natriuretic peptide, NYHA: New York Heart Association, pts: patients
(*)Other biomarkers of injury or fibrosis include soluble ST2 receptor, galectin-3, and high-sensitivity troponin.
Biomarkers of Myocardial Injury: Cardiac Troponin T or I
Even without obvious myocardial ischemic injury, troponin level may be increased in heart failure which means undergoing myocyte injury.[11] Elevated levels of troponin is associated with impaired hemodynamics, progressive LV dysfunction and increased mortality rates.[12]
Carbohydrate Antigen 125
CA-125 is an emerging, highly sensitive biomarker for heart failure.[13] Although it is not yet used in clinical practice, the CHANCE-HF trial has demonstrated utility in using CA-125 to guide diuretic therapy and for determining short-term prognosis.[14] CA-125 is a non-specific antigen that is most strongly associated with ovarian cancer. In patients with acute heart failure, ambulatory follow-up care aimed at titrating diuretic use according to CA-125 levels has demonstrated ~50% reduction in rehospitalizations.[14] CA-125 was first associated with heart failure in 1999 by Nagele et al.[13][15]
