• 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).

• Aortic Aneurysm
• Arrhythmia

  Arrhythmias

  An arrhythmia is an abnormal heart rhythm that can cause problems with the contractions of your heart chambers. An arrhythmia occurs when there is a problem with the electrical system that is supposed to regulate a steady heartbeat. With an impaired electrical system, your heart may beat too fast, too slow, or irregularly.

• 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 CT Angiography

  Computed Tomography Angiography

  CT angiography is a type of medical test that combines a CT scan with an injection of a special dye to produce pictures of blood vessels and tissues in a part of your body.

• 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.

• 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.

• 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.

  Cardiovascular diseases include coronary heart disease, stroke, high blood pressure, and rheumatic heart disease.

• 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.

• 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 (Heart)
• Nuclear Cardiology
• Nuclear Stress Testing

  Stress Myocardial Perfusion Scan

  Myocardial perfusion is an imaging test. It's also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping. For example, after a heart attack, it may be done to find areas of damaged heart muscle. This test may be done during rest and while you exercise.

• Syncope

  A Serious Look at Fainting

  Fainting (syncope) is a brief loss of consciousness. This leads to falling down or needing to lie down, followed by a quick recovery. Fainting by itself is not a problem, but it could be a sign of a serious health condition.

• 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.
