Panel of blood tests measuring cholesterol components to assess the risk of heart
disease
A lipid panel consists of total cholesterol, high-density lipoprotein (HDL), low-density
lipoprotein (LDL), and triglycerides.
Test in which an ECG is recorded under controlled exercise conditions (typically
using a treadmill) to determine the heart’s response to physical exertion (stress)
A stress test may show abnormal ECG tracings that do not appear during an ECG
taken when the patient is resting.
Stress test that uses a radioisotope to evaluate coronary blood flow
In a nuclear stress test, the radioisotope is injected at the height of exercise. The area not
receiving sufficient oxygen is visualized by decreased uptake of the isotope.
Blood test that measures protein released into the blood by damaged heart muscle
(not skeletal muscle)
The troponin I test is a highly sensitive and specific indicator of recent myocardial
infarction (MI).
