A simple blood test can detect emphysema in smokers before the first symptoms appear, reports the American Journal of Respiratory and Critical Care Medicine.
Periodic blood tests allow you to assess the condition of the heart, liver and kidneys. The new test, developed by scientists at New York – Presbyterian Hospital / Weill Cornell, can also detect damage to lung tissue.
The test is primarily intended to help smokers, especially those at risk of damage to the pulmonary parenchyma. Smoking-related emphysema and chronic inflammation of the bronchi, collectively known as COPD (chronic obstructive pulmonary disease), are an important cause of death in the long term. The earlier treatment is started, the better the chances of a longer life. COPD does not develop in all smokers; early detection can be a significant incentive to quit smoking.
The test is based on the detection of endothelial molecules (EMPs) detaching from tiny blood vessels called capillaries that surround the alveoli in the lungs. It is the alveoli entwined with capillaries that enable gas exchange. Destroying the bubbles makes breathing difficult, and with time even impossible (PAP).
