Ashd (atherosclerotic heart disease) Evaluation
- Congested lungs:
- Rales on auscultation of the lung fields
- Creased ear lobe
- Excessive sweating
- Heart murmur
- High blood pressure
- Low blood pressure
- Irregular heartbeat
- Rapid pulse
- Swelling of the legs and feet
- Swelling of the veins in the neck
Testing is necessary to confirm the diagnosis of coronary artery disease.
Tests that may be used to evaluate coronary artery disease include:
- Cardiac enzymes
- C-reactive protein
- Cholesterol level
- Triglyceride level
Other tests that may be used to evaluate coronary artery disease include:
- Chest x-ray:
- Exercise stress test
- Cardiac catheterization
- Intracoronary ultrasound:
- Shows images of the inside of coronary arteries
- MRI scan of the heart:
- Shows detailed images of the heart and coronary arteries
- Detects structural abnormalities of the heart
- MUGA scan
- SPECT scanning of the heart:
- Detects blood flow abnormalities to heart muscle
- Thallium heart scan
- Coronary artery CT scanning:
- Checks for possible obstructions in the coronary arteries
- Can show a build-up of calcium in a coronary artery
- Rubidium PET/CT scanning of the heart:

Ashd (atherosclerotic heart disease) Electrocardiogram
An electrocardiogram or ECG can be an effective tool in detecting coronary artery disease.
How an ECG Works
An electrical impulse stimulates the muscle fibers in the heart to contract. The impulse spreads through the heart in a very organized manner. The heart's normal electrical impulse has a characteristic pattern. The EKG machine displays the pattern of the electrical impulse.
Abnormal electrical patterns on the EKG can help identify heart disease.
The EKG can identify:
Ashd (atherosclerotic heart disease) Heart Catheterization
Cardiac catheterization and coronary angiogram are effective tools for detecting coronary artery disease.
How Heart Catheterization Works
During a cardiac catheterization, a catheter (thin plastic tube) is inserted into an artery in the groin, and then threaded up through the aorta to the heart. The catheter can be used to inject x-ray dye into the coronary arteries that supply the heart. An x-ray machine is used to take pictures of the dye inside the coronary arteries. This procedure is referred to as coronary angiography. Using these procedures doctors can detecting narrowing or obstruction of the coronary arteries.
Ashd (atherosclerotic heart disease) Thallium Stress Test
Thallium stress testing is an effective tool for detecting coronary artery disease.
How Thallium Stress Testing Works
The thallium stress test identifies areas of the heart muscle that receive reduced blood flow from narrowed or blocked coronary arteries. During the test, thallium is injected into the bloodstream. Heart muscle cells collect the thallium in the bloodstream. If blood flow is reduced through one of the coronary arteries, then the muscle cells that are supplied by that artery do not collect as much thallium as muscle cells that receive normal blood flow. A special camera is used to detect thallium in the heart muscle and a computer constructs images of the heart. The images show areas that receive reduced blood flow.
