Symptoms
How We Can Help You
When caring for symptoms like chest pain, our doctors know when to look beyond the blocked arteries that define obstructive coronary artery disease (CAD). They recognize that your heart’s arteries sometimes suffer from non-obstructive coronary artery disease.
This less common form of CAD occurs when your heart’s arteries inappropriately constrict, malfunction after branching into tiny vessels, or are squeezed by the overlying heart muscle. While much work remains to fully understand non-obstructive coronary artery disease, our doctors lead the way in providing answers through ongoing research to improve diagnosis and treatment.
We treat non-obstructive coronary artery disease through the Interventional Cardiology Program.
WHAT WE OFFER YOU FOR NON-OBSTRUCTIVE CORONARY ARTERY DISEASE
- Nationally recognized expertise in non-obstructive coronary artery disease, with one of the country’s most comprehensive programs.
- Advanced diagnostic testing for those with chest pain but no blockages, including testing for endothelial dysfunction, microvascular dysfunction, and myocardial bridging.
- Team-based care that bring together specialists from interventional cardiology, cardiac surgery, and imaging.
- Comprehensive treatment options, including lifestyle changes, medication, minimally invasive options, and surgery.
- Care tailored to the needs of women and men, who often experience heart disease differently. Our program is one of the few able to provide this level of care.
- Extensive lifestyle support to lower stress, improve diet, and promote health. Our psychological support program for heart care is one of the nation’s largest.
- Active clinical research into new diagnostic and treatment approaches. Our program continues to provide much of the data validating today’s treatment options.

What Is Non-Obstructive Coronary Artery Disease?
Treatment for Non-Obstructive Coronary Disease
Treatment for non-obstructive coronary disease depends on the type of disease you have:
- Endothelial dysfunction is a problem with the lining inside the artery causing inappropriate constriction.
- Coronary vasospasm (Prinzmetal’s angina) is a constriction due to the smooth muscle cells.
- Microvascular dysfunction is a malfunction of the small branches of the coronary arteries.
- Myocardial bridging is a congenital variant in which overlying heart muscle squeezes an artery. Myocardial bridges are common and most cause no problems, but some can cause chest pain and arrhythmia.
DID YOU KNOW?
Non-obstructive coronary artery disease affects women more frequently than men. Stanford’s Women’s Heart Health Clinic offers the specialty care women need.
Our doctors use the most effective and current approaches. We listen to your concerns and evaluate your entire coronary circulation. Our doctors test until they find the cause of your chest pain or other symptoms, and work with you to develop a treatment plan, which may include one or a combination of the following:
Lifestyle Changes
Lifestyle changes to control risk factors may provide appropriate treatment if non-obstructive coronary artery disease is caused by endothelial or microvascular dysfunction. Our team of psychologists, dieticians, and other specialized heart care staff will support you in adopting a heart-healthy lifestyle.
Medications
Most people with non-obstructive coronary artery disease will need medical therapy to improve their symptoms. Our doctors may recommend medication alone, or in combination with stress reduction and other lifestyle changes.
Surgery
Surgery is an option for myocardial bridging, offered only as needed when medications fail. During a special operation called unroofing, our surgeons remove the heart muscle sitting over the artery. They use a detailed map, created during a cardiac catheterization, that shows the precise location of the bridge. Our surgeons have completed the most unroofing surgeries in the country.
Clinical Trials
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently recruiting participants or that may recruit participants in the near future. Closed trials are not currently enrolling, but similar studies may open in the future.

We constantly search for better ways to protect your heart and blood vessels. The following are some examples of our ongoing clinical innovation.
- Using the radial artery: Programs like ours traditionally reach the heart through an artery in the groin. We were among the first to use the wrist’s radial artery, for greater comfort, less bleeding, and quicker recovery. Many people undergoing angioplasty can safely go home the same day.
- Improving stent treatment: We helped develop and quickly adopted specialized cardiac catheterization testing to measure the pressure and flow of blood and see inside clogged arteries to precisely place stents. We offer the first stent that dissolves after opening your artery, with no metal used or left in your body.
- Combining angioplasty with bypass: Before, blocked arteries often required open-heart surgery when angioplasty was not possible. Our hybrid coronary revascularization provides a new alternative, stenting some arteries and bypassing others. We do not open your chest or stop your heart.
- Advancing valve treatment: We were the first hospital in Northern California to perform transcatheter aortic valve replacement (TAVR). We also have extensive experience with transcatheter mitral valve repair (TMVR). We provide options for people who cannot undergo surgery, with the potential to expand these treatments.
- Lowering stroke risk: We were the first center in Northern California to offer the WATCHMAN™ device once it gained FDA approval. We use it for left atrial appendage closure, reducing stroke risk for atrial fibrillation. We plan to study other stroke-reducing devices as they become available.
