The cardiovascular system includes the heart and the blood vessels that carry oxygen and nutrients throughout the body. Because nearly every organ depends on steady blood flow, heart health plays a foundational role in maintaining overall health. A physician may recommend a cardiovascular screening if you experience symptoms like chest discomfort, shortness of breath, or an irregular heartbeat. You also have higher health risk factors if you have a family history of heart disease. Here’s information on the benefits of different cardiovascular health screenings:
A Stress Echocardiogram
After a technician records images of the heart at rest, they can perform a stress echocardiogram. This cardiovascular screening option combines a heart ultrasound with physical activity. During this type of echocardiogram, you walk on a treadmill or pedal a stationary bike until your heart reaches a target rate. Immediately after exercise, the technician captures a second set of images for comparison. A provider may use medication instead to raise your heart rate if you cannot exercise.
Physicians may recommend this test to evaluate how the heart muscle and valves work under exertion. It helps identify areas of the heart that may not receive adequate blood flow during activity. A stress echocardiogram does not use radiation, and it typically takes about an hour to complete. This information can guide decisions about further testing, medication adjustments, or activity recommendations within your healthcare plan.
A Transesophageal Echocardiogram
A transesophageal echocardiogram (TEE) also uses ultrasound to image the heart. The key difference is where the ultrasound device is placed. During a stress echocardiogram, the technician places a transducer on the outside of the chest. During a TEE, a provider guides a thin, flexible tube with a small transducer down the throat and into the esophagus. A TEE also differs in preparation and recovery.
You will typically need to avoid eating or drinking for several hours beforehand. Most patients receive a sedative and a throat-numbing spray before the procedure begins. A TEE focuses on the heart’s structure at rest; a stress echocardiogram evaluates function during activity. Because of the sedation, you will need someone to drive you home afterward.
The esophagus sits directly behind the heart; this position allows the transducer to produce detailed images without interference from the:
- Ribs
- Lungs
- Chest Wall
Providers may use a TEE to examine heart valves, look for blood clots, or more closely evaluate the heart’s upper chambers.
A Nuclear Stress Test
Nuclear stress testing uses a small amount of radioactive tracer to show how blood flows to the heart muscle. A provider injects the tracer into a vein in your arm, and a special camera then detects the tracer and creates images of the heart. Like a stress echocardiogram, this test compares the heart at rest and under stress.
The full process can take several hours, since the tracer needs time to circulate between imaging sessions. Physicians may recommend nuclear stress testing when an exercise stress test or echocardiogram does not provide enough information. You may be asked to avoid caffeine and certain medications for a set period before the test.
The tracer leaves the body naturally over time, and your provider may recommend drinking extra fluids afterward. You will typically have one set of images taken at rest and another after exercise or medication raises your heart rate. Comparing the two sets can help show areas of the heart muscle that receive less blood flow during activity.
Learn About Your Cardiovascular Health
Cardiovascular health screenings provide information about how your heart is built and how it performs, helping many build personalized heart health plans. Your provider can explain which screening fits your symptoms, risk factors, and medical history. To determine what screening you need, contact a cardiologist to schedule an evaluation.
