DIAGNOSTIC INVESTIGATIONS: X-RAYS & CLINICAL LABORATORY TESTS

Q. Are X-rays also used in the diagnosis of heart diseases?

A. Yes, X-rays of the chest are helpful in determining the size of the heart. An enlarged heart shadow indicates an overburdened heart. Signs of failure of heart function (left ventricular failure), which causes difficulty in breathing, may be seen in the lung fields, which become congested, i.e., the lung fields, which are normally translucent, become more opaque. Punctate opacities and blood vascular markings become more prominent. Effects of therapy can be measured by comparing successive X-rays.

CLINICAL LABORATORY TESTS

Q. What are the various clinical laboratory tests commonly performed on patient suffering from heart diseases?

A. The most commonly performed tests are:

• Blood lipid (fat) estimation.
• Blood sugar estimation.
• Blood uric acid estimation.
• Cardiac enzyme levels estimation.
• Urinalysis.
• White blood cell count.
