About Me

Tamara Horwich, MD, MS is an attending cardiologist and Health Sciences Associate Clinical Professor of Medicine/Cardiology at the David Geffen School of Medicine at UCLA. She is Medical Director of UCLA's Cardiac Rehabilitation Program, including the Dr. Dean Ornish Comprehensive Lifestyle Program for Reversing Heart Disease, Co-Director of the UCLA Women's Cardiovascular Health Center, and an active member of the Ahmanson-UCLA Cardiomyopathy Center.

Dr. Horwich's clinical interests include treating and preventing heart disease in women, cardiac rehabilitation, treating patients with heart failure, and performing and interpreting echocardiograms. Dr. Horwich's main research interests include studying obesity, body composition and cardiovascular disease, as well as risk factors and novel therapies for patients with heart disease, with a focus on women. She has been a grant recipient from the National Institutes of Health, the Heart Failure Society of America, as well as the Iris Cantor Women's Center at UCLA. Dr. Horwich is a Fellow of the American College of Cardiology and American Heart Association and has helped draft national guidelines on management of heart failure. Furthermore, she is a frequent invited speaker and moderator at the scientific sessions of the American Heart Association, American College of Cardiology, and Heart Failure Society of America. Dr. Horwich received a BA in History from Brown University and an MD from the Columbia University College of Physicians and Surgeons. She then returned to her native Los Angeles to complete internal medicine residency and cardiology fellowship training at UCLA, during which time she also attained a Master’s of Science in Clinical Research from UCLA.

Interests
  • 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.

  • Cardiac Imaging
  • Cardiac Rehabilitation

    Cardiac Rehabilitation

    Cardiac rehabilitation is a program to help people who have heart disease. It is designed to improve heart recovery, improve your ability to function, and prepare you for future daily activities. People in this program may have had a heart attack or heart surgery. Cardiac rehabilitation programs are overseen by a healthcare provider and can be conducted while a person is a hospital inpatient or on an outpatient basis.

  • 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.
    Learn more >
  • Heart Transplant Evaluation

    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 >
  • 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).

  • Ischemia
  • Transesophageal Echocardiogram (TEE)
  • 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.
