Heart failure
CHF; Congestive heart failure; Left-sided heart failure; Right-sided heart failure - cor pulmonale; Cardiomyopathy - heart failure; HFHeart failure is a condition in which the heart is no longer able to pump oxygen-rich blood to the rest of the body efficiently. This causes symptoms to occur throughout the body.

Primary pulmonary hypertension
Pulmonary hypertension is the narrowing of the pulmonary arterioles within the lung. The narrowing of the arteries creates resistance and an increased work load for the heart. The heart becomes enlarged from pumping blood against the resistance. Some symptoms include chest pain, weakness, shortness of breath, and fatigue. The goal of treatment is control of the symptoms, although the disease usually develops into congestive heart failure.

Osmolality test
An osmolality urine test is performed to measure the concentration of particles in urine. Greater than normal results may indicate conditions such as Addison disease, congestive heart failure or shock. Lower-than-normal measurements may indicate aldosteronism, diabetes insipidus, excess fluid intake, renal tubular necrosis or severe pyelonephritis.
