About Me

Dr. Nsair is the Director of the Heart Transplantation and Mechanical Circulatory Support Program at UCLA. As well, he is a member of the Interventional and structural program at UCLA. He received his MD from the University of Alberta, where he also completed his Internal Medicine residency and Cardiology fellowship. He received advanced training in Advanced Heart Failure and Interventional Cardiology at UCLA Medical Center and a post-doctoral fellowship in Regenerative Therapies. His research interests include cardiovascular regenerative and rejuvenation therapies, as well as advanced studies of mechanical circulatory support devices in cardiogenic shock and novel heart failure medical therapies.

Dr. Nsair has strong interest in sports medicine and extensive expertise in managing cardiovascular disease in patients of all athletic levels. As well he is a skilled proceduralist in coronary and structural heart interventions. Current research interest focuses on implantable and wearable technologies in heart failure patients and athletics. Furthermore, his research interest involves mechanical circulatory support in patients with advanced heart failure and cardiogenic shock. He is involved in multiple clinical and translational trials and is the PI for a basic and translational research lab.

Interests

Angina
Angina Pectoris
Angina pectoris (or simply angina) is chest pain or discomfort that keeps coming back. It happens when some part of your heart doesn't get enough blood and oxygen. Angina can be a symptom of coronary artery disease (CAD).

Atherosclerosis
Atherosclerosis
Atherosclerosis is a type of thickening or hardening of the arteries caused by a buildup of plaque in the inner lining of an artery. It can increase your risk of heart attack, stroke, and other circulatory conditions.

Atrial Fibrillation
Cardiac Biopsy
Cardiac Catheterization
Cardiac Catheterization
In cardiac catheterization (often called cardiac cath), a very small hollow tube, or catheter, is advanced from a blood vessel in the groin or arm through the aorta into the heart. Once it is in place, several diagnostic and treatment procedures can be done using catheterization.
Learn more >
Cardiomyopathy
Cardiomyopathy
Any disorder that affects the heart muscle is called a cardiomyopathy. Cardiomyopathy causes the heart to lose its ability to pump blood well. In some cases, the heart rhythm also becomes disturbed. This leads to arrhythmias (irregular heartbeats).
Learn more >
Cholesterol
Cholesterol in the Blood
The cholesterol in your blood comes from the foods you eat and your liver. Your liver makes all of the cholesterol your body needs. It helps your body make cell membranes, many hormones, and vitamin D.
Learn more >
Congestive Heart Failure
Heart Failure
When you have heart failure, the heart is not able to pump as well as it should. Blood and fluid may back up into the lungs (congestive heart failure), and some parts of the body don’t get enough oxygen-rich blood to work normally.
Learn more >
Coronary Artery Disease
Coronary Heart Disease
A person with coronary heart disease has an accumulation of fatty deposits in the coronary arteries. These deposits narrow the arteries and can decrease or block the flow of blood to the heart.

General Cardiology
Home Page - Cardiovascular Diseases
Cardiovascular diseases include coronary heart disease, stroke, high blood pressure, and rheumatic heart disease.

Heart Transplant
Heart Transplant
A heart transplant is surgery to remove the diseased heart from a person and replace it with a healthy one from an organ donor. To remove the heart from the donor, two or more healthcare providers must declare the donor brain-dead.
Learn more >
Heart Transplant After Surgery
Heart Transplant
A heart transplant is surgery to remove the diseased heart from a person and replace it with a healthy one from an organ donor. To remove the heart from the donor, two or more healthcare providers must declare the donor brain-dead.
Learn more >
Heart Valve Disease
Heart Valve Diseases
Heart valves can malfunction on one of two ways: They can fail to close completely, allowing blood to flow backward, or they can become damaged, limiting blood flow. Your doctor may think you have heart valve disease if your heart sounds heard through a stethoscope are abnormal.
Learn more >
Hypertension
High Blood Pressure/Hypertension
Blood pressure is the force of the blood pushing against the artery walls. The force is created with each heartbeat as blood is pumped from the heart into the blood vessels. Blood pressure is also affected by the size of the artery walls and how elastic they are. Each time the heart beats (contracts and relaxes), pressure is created inside the arteries. High blood pressure, or hypertension, increases the risk for coronary heart disease (heart attack) and stroke (brain attack).
Learn more >
Ischemia (Heart)
Transthoracic Echocardiography
Transesophageal Echocardiogram
A transesophageal echocardiogram (TEE) uses echocardiography to assess how well the heart works. During the procedure, a transducer (like a microphone) is lowered into the esophagus. It sends out ultrasonic sound waves at a frequency too high to be heard. When the transducer is placed at certain locations and angles, the ultrasonic sound waves move through the skin and other body tissues to the heart tissues, where the waves bounce or "echo" off of the heart structures.
