Coronary artery disease (CAD) is the narrowing of the arteries that supply blood to the heart, usually caused by plaque buildup. At Cypress Cardiovascular Institute, board-certified interventional cardiologists led by Dr. Jad Daye, MD diagnose and treat CAD, from risk-factor management and medication to cardiac catheterization, angioplasty and stenting, for patients in Cypress and northwest Houston.

Understanding CAD
Coronary artery disease is the most common type of heart disease in the United States. It develops when plaque, made of cholesterol, fat and other substances, builds up inside the coronary arteries. This buildup, called atherosclerosis, narrows the arteries and can reduce the oxygen-rich blood that reaches the heart muscle.
Reduced blood flow can cause chest pain (angina) or shortness of breath. If a plaque ruptures and a blood clot blocks an artery, it can cause a heart attack. CAD often develops over many years, and some people have no symptoms until they have a heart attack, which is why checking your risk factors matters.
Symptoms
Coronary artery disease symptoms often appear during physical activity or emotional stress, when the heart needs more oxygen. Some people, especially women, older adults and people with diabetes, have subtle or atypical symptoms.
Tightness, squeezing or heaviness in the chest that may spread to the shoulders, arms, neck, jaw or back, often brought on by exertion.
Breathlessness during activities you could previously do comfortably can be a sign that the heart is not getting enough blood.
Tiredness or lower exercise tolerance, which is sometimes the main symptom in women and older adults.
Pain in the jaw, neck, upper back or arm can come from the heart even when there is no chest pain.
Cold sweats, nausea or dizziness, especially together with chest discomfort, can signal reduced blood flow to the heart.
For some people, the first sign of coronary artery disease is a heart attack. Symptoms that last more than a few minutes need emergency care.
Call 911 if you have chest pain or pressure that lasts more than a few minutes, goes away and comes back, or occurs with shortness of breath, sweating, nausea or lightheadedness. Do not drive yourself to the hospital.
Causes & Risk Factors
Coronary artery disease is caused by atherosclerosis, the gradual buildup of plaque in artery walls. Several risk factors speed up that process. Some can be changed with lifestyle and treatment; others, such as age and family history, cannot. A cardiologist can assess your individual risk and recommend testing when it is needed.
Diagnosis
Diagnosis starts with a cardiology visit. Your cardiologist reviews your symptoms, medical history and risk factors, checks your blood pressure and heart rhythm, and then orders the tests that fit your situation. Many of these tests are available at our Cypress offices and imaging center.
Records the heart’s electrical activity to look for signs of reduced blood flow, a previous heart attack or rhythm problems.
An ultrasound of the heart that shows how well the heart muscle and valves are pumping.
Monitors your heart while you exercise to see whether symptoms or EKG changes appear when the heart works harder.
Imaging with a small amount of tracer shows how well blood reaches the heart muscle at rest and under stress.
A CT scan with contrast dye that creates detailed images of the coronary arteries and plaque.
Coronary angiography uses contrast dye and X-ray imaging to show exactly where arteries are narrowed. FFR, IVUS or OCT may be used to measure a blockage.
Learn more about each test on our Diagnostic & Imaging Services page.
Treatment Options
Coronary artery disease treatment aims to relieve symptoms, slow plaque buildup and lower the risk of a heart attack. Most patients start with lifestyle changes and medication. When an artery is severely narrowed or symptoms continue, a minimally invasive catheter-based procedure may be recommended.
| Treatment | How it works | Typically considered when |
|---|---|---|
| Lifestyle changes | Heart-healthy eating, regular physical activity, quitting tobacco and weight management lower cardiovascular risk. | For everyone with coronary artery disease or its risk factors. |
| Medications | Medicines can lower cholesterol and blood pressure, help prevent clots (antiplatelet therapy) and relieve angina. | For most patients, alone or together with a procedure. |
| Angioplasty and stenting (PCI) | A catheter is guided to the narrowed coronary artery; a balloon opens it and a stent helps keep it open. | Significant narrowing with symptoms not controlled by medication, or during a heart attack. |
| Coronary artery bypass surgery (CABG) | A cardiac surgeon uses a blood vessel from elsewhere in the body to route blood around blocked arteries. | Complex or multi-vessel disease. Our cardiologists coordinate referral to a cardiac surgeon. |
| Cardiac rehabilitation | A supervised program of exercise, education and risk-factor support. | After a heart attack, stenting or bypass surgery, when recommended by your cardiologist. |

Frequently Asked Questions
A cardiologist diagnoses and manages coronary artery disease. An interventional cardiologist, like the physicians at Cypress Cardiovascular Institute, can also perform catheter-based procedures such as coronary angiography, angioplasty and stenting to open narrowed arteries.
Plaque that has already formed usually cannot be fully removed, but coronary artery disease can often be controlled. Medication, lifestyle changes and procedures can relieve symptoms, slow plaque buildup and lower the risk of a heart attack.
No. Chest pain has many possible causes, including muscle, lung and digestive problems. Because chest pain can also signal reduced blood flow to the heart, it should be evaluated promptly. Call 911 for severe or persistent chest pain.
Recovery depends on how many arteries are treated and whether the procedure was planned or done during a heart attack. Many patients go home the same day or after an overnight stay. Your cardiologist will explain activity limits and follow-up for your specific case.
Many patients can schedule directly with Cypress Cardiovascular Institute. Some insurance plans, especially HMOs, require a referral. Call (281) 955-9158 and our team will check your coverage.
Cypress Cardiovascular Institute accepts Medicare, Medicaid and most major insurance plans. Medically necessary cardiology visits, testing and procedures are usually covered, but copays and prior-authorization rules vary by plan, so we recommend verifying your benefits.
