There are several tests that can be done in the evaluation of Coronary Heart Disease. These include:
1.) EKG–This is an electrical tracing of your heart, and can help detect any changes in blood flow to the heart, and help determine if someone is having a heart attack, or if they have had one in the past. It only takes a few minutes, and is painless.
2.) A Stress Test–You are monitored continuously with an EKG tracing, and then start walking on a treadmill, such as the one pictured. Every 3 minutes, the speed and the incline of the treadmill increase. We are trying to evaluate not only your exercise capacity/limit, but also help determine if your heart is getting enough blood with activity. We are “stressing” your heart.
3.) An Echocardiogram–it is basically an ultrasound of your heart, giving us information about your heart valves, and how well your heart contracts when it is beating.
4.) A cardiac catheterization, or angiogram–the large vessels in the groin of your leg have a catheter placed and dye is injected to evaluate the coronary vessels of the heart. This is where we can see exactly where blockages exist, and then can place a stent where necessary if blockage is present.
5.) A cardiac score/calcium score–This is a CT scan of the coronary vessels of your heart, and if the amount of calcium present in the coronary vessels are increased, this is also a risk factor with blockage of the vessel going forward. It to is painless, and takes only a few minutes.
Overall, what everyone needs to keep in mind is that if they are experiencing increasing shortness of breath with activity, or chest pain, then you need to see your doctor to decide on which tests above need to be performed in order to help evaluate you.
The final upcoming segment on coronary heart disease will be dealing with how to treat it. Keep moving everybody!
