A network of coronary arteries (macro-vessels) that branch off into smaller vessels (micro-vessels) supplies the heart muscle with blood. Narrowing of these vessels at either the macro or micro level limits the amount of blood that the heart muscle receives (ischemia) and causes chest pain (angina) at rest or during exertion. This, in turn, causes several important heart problems such as:
  • Myocardial infarction (heart attack)
  • Heart failure (poor heart pump function)
  • Cardiac arrhythmias (life threatening abnormal heartbeat)
  • Limited exercise tolerance due to angina (chest pain) or dyspnea (shortness of breath)
The most known narrowing of the heart vessels is when cholesterol deposits in the walls of the coronary arteries – coronary artery disease (CAD). Managing CAD starts from preventive measures and reaches up to interventions such as inserting stents that open these arteries. On the other hand, not infrequently patients complain of chest pain that originates from the smaller heart vessels. Women are more prone to this condition. Diagnosing this condition remains challenging, as a regular coronary catheterization does not evaluate the small vessels. Thus, diagnosing and managing this condition requires specialized expertise and equipment.

Mission and Vision

The mission of our unit is to provide an exemplary level of care and outcomes to our patients with heart blood vessel disease. The highest quality of integrated diagnostics and the latest evidence-based and multidisciplinary practice will be applied to serve our population. Our Vision is to be a distinctive and state of art center that manages patients at risk and patients with coronary artery disease with transformative cutting-edge science and patient-centered care.

A Multidisciplinary approach

The multidisciplinary team involves distinguished cardiologists, Exercise and Physical therapy specialists, dedicated dietitians, an experienced team of nurses, and a well-trained number of coordinators. All our team members work in a structured manner to make sure our patients are receiving a thorough and customized treatment for CAD. Our Specialists in the Coronary Macro & Micro vessel Disease unit help patients who:


Our cardiologist collects medical history from each patient, perform a physical exam and order routine blood tests. He or she may suggest additional diagnostics including:

Electrocardiogram (ECG)

An electrocardiogram records electrical signals as they travel through your heart. An ECG can often reveal evidence of a previous heart attack or one that’s in progress.


During an echocardiogram, your doctor can determine whether all parts of the heart wall are contributing normally to your heart’s pumping activity.

Parts that move weakly may have been damaged during a heart attack or be receiving too little oxygen. This may be a sign of coronary artery disease or other conditions.

Exercise stress test

If your signs and symptoms occur most often during exercise, your doctor may ask you to walk on a treadmill, a stationary bike, or pharmacologic stress test with ECG monitoring. Sometimes, an echocardiogram is also done while you do these exercises. This is called a stress echo.

Cardiac catheterization and angiogram

Cardiac catheterization is an invasive diagnostic procedure that provides important information about the structure and function of the heart. It usually involves taking X-rays of the heart’s arteries (coronary arteries) using a technique called coronary angiography or arteriography.

Cardiac CT scan

A CT scan of the heart can help your doctor see narrowing in the coronary arteries in your heart vessels. Preparation for this test may require taking a medication to control your heart rate and on the day of the test an IV line is inserted for contrast administration.

Cardiac MRI

A cardiac MRI test can help confirm that areas of the heart muscle are not well supplied with blood in addition to learning if these areas are still alive and can be saved.

Provocative pharmacological testing

To evaluate for endothelial dysfunction, microvascular dysfunction, and significant myocardial bridging. During this test, your coronary vessels will be injected with pharmacological agents and the resistance and blood flow in the large coronary and micro (small) coronary vessels not visible by angiography will be measured. Depending on the results, we can tell if the abnormalities in the blood flow in the small vessels are the cause of your chest pain (angina) and drug treatment can be tailored accordingly to address this issue.

Treatment options

Our goal is to provide you the best possible treatment that keeps you healthy and active.

Obstructive Coronary Artery Disease

We use cardiac catheterization to look for narrowed or blocked arteries and to determine their severity and urgency.

Multiple options are available depending on your condition:

After treatment, you may need regular checkups. Our team of cardiologists, nurses, and dieticians provides all possible follow-up care.

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.

What we offer you for non-obstructive coronary artery disease?

Spontaneous Coronary Artery Dissection (SCAD)

Spontaneous coronary artery dissection (SCAD) happens when layers in the artery wall tear apart without warning, and partially or completely block blood flow to the heart. This condition typically presents as a heart attack and is often misdiagnosed. SCAD most frequently affects women, many of them young and otherwise healthy.
