Heart & Vascular Testing
Cardiac and vascular tests show how the heart and blood vessels are working. They measure the heart’s electrical activity, pumping strength and blood flow, reveal narrowed or blocked arteries, and record the heart rhythm over time. The results help your cardiologist confirm a diagnosis, choose the right treatment and track your progress.
Most heart tests are noninvasive, meaning no incision is needed. Examples include EKGs, ultrasound and stress tests. Invasive tests such as cardiac catheterization are used when more detailed information is needed or when treatment may be performed during the same procedure.
Reasons for Testing
Your cardiologist recommends tests based on your symptoms, risk factors and medical history. These are some of the most common reasons for heart and vascular testing.
Stress tests, nuclear imaging or CT angiography can show whether reduced blood flow to the heart is causing symptoms.
An echocardiogram measures how well the heart muscle and valves are working.
An EKG and a Holter or event monitor record the heart rhythm to identify arrhythmias.
Ankle-brachial index testing and leg arterial ultrasound check for peripheral artery disease.
Ultrasound can evaluate the leg veins as part of a vein care evaluation.
Follow-up testing and pacemaker or defibrillator checks track your condition and confirm devices are working properly.
Call 911 for chest pain, severe shortness of breath, fainting or stroke symptoms. Emergency symptoms should be evaluated in an emergency department rather than at a scheduled test appointment.
Imaging Center
Cypress Cardiovascular Institute operates an imaging center in Suite 345 of the Methodist Cypress medical office building (MOB2), in the same building as the practice’s main office in Suite 325. Having testing and cardiology visits in one location makes it easier to complete your evaluation and review results with your cardiologist. For your test, please bring:
Heart Tests
These cardiac tests evaluate the heart’s rhythm, structure, pumping function and blood flow.
A quick, painless recording of the heart’s electrical activity using small sensors on the chest. It helps detect arrhythmias, signs of a heart attack and heart strain.
An ultrasound of the heart that shows its size, pumping strength and valves, without radiation.
Records your EKG, heart rate and blood pressure while you walk on a treadmill to see how the heart responds to exercise.
A stress myocardial perfusion scan uses a small amount of radioactive tracer to show blood flow to the heart muscle at rest and during stress.
Positron emission tomography imaging of the heart shows blood flow and helps distinguish healthy heart muscle from damaged muscle.
Portable monitors record your heart rhythm for 24 hours or longer during daily activities to capture arrhythmias that come and go.
Pacemaker and defibrillator checks are also available for patients with implanted devices. See how testing fits into care for coronary artery disease and heart failure and arrhythmias.
Vascular & Advanced Imaging
Vascular tests check the arteries and veins outside the heart, and advanced imaging provides detailed pictures when standard tests are not enough. The table below explains what each test shows and when it is often used.
| Test | What it shows | Often used for |
|---|---|---|
| Ankle-brachial index (ABI) | Compares ankle and arm blood pressure to detect narrowed leg arteries. | Screening for and diagnosing peripheral artery disease. |
| Leg arterial ultrasound | Blood flow through the leg arteries using Doppler ultrasound. | Locating PAD blockages and follow-up after treatment. |
| Carotid ultrasound | Plaque and narrowing in the neck arteries that supply the brain. | Assessing stroke risk. |
| Abdominal aortic ultrasound | The size of the abdominal aorta. | Checking for an abdominal aortic aneurysm. |
| CT angiography (CTA) and cardiac CT (CCTA) | Detailed 3D images of arteries and plaque using contrast dye. | Evaluating coronary and peripheral arteries. |
| Magnetic resonance angiography (MRA) | Images of blood vessels made with magnets and radio waves instead of X-rays. | Evaluating arteries when CT is not the preferred option. |
| Transesophageal echocardiogram (TEE) | Close-up ultrasound images of the heart taken from the esophagus under sedation. | Detailed valve evaluation and checking for clots in the heart. |
| Impedance cardiography (ICG) | A noninvasive estimate of how much blood the heart pumps and fluid in the chest. | Guiding treatment of high blood pressure and heart failure. |
| Cardiac catheterization and angiography | X-ray images with contrast dye inside the arteries; FFR, IVUS and OCT measure blockages in detail. | Confirming blockages and planning or performing angioplasty and stenting. |
Test availability, location and preparation can vary. Our staff will confirm the details when your test is scheduled.

Frequently Asked Questions
Yes. Diagnostic heart and vascular tests are ordered by a physician. At Cypress Cardiovascular Institute, a cardiologist evaluates you first and orders the tests that fit your symptoms and risk factors. Some insurance plans also require a referral.
An EKG records the heart’s electrical activity and takes a few minutes. An echocardiogram uses ultrasound to create moving pictures of the heart, showing its size, pumping strength and valves. They answer different questions, so your cardiologist may order both.
Nuclear stress tests are commonly performed and use a small amount of radioactive tracer that leaves the body naturally. Tell your care team if you are pregnant or breastfeeding. If you cannot exercise, medication can be used to stress the heart instead.
An EKG takes a few minutes. An echocardiogram usually takes under an hour, and a nuclear stress test can take a few hours because images are taken at rest and after stress. Our team will tell you how long to plan for.
The imaging center is at Methodist Cypress (MOB2), 24518 Northwest Fwy, Suite 345, Cypress, TX 77429, in the same building as the practice’s main office in Suite 325.
