Diseases & Conditions

The more you know about your heart and vascular condition, the better prepared you’ll be to maintain your cardiovascular health. At West Suburban Medical Center, we stay up-to-date on the latest heart diseases and vascular conditions and share our knowledge and expertise with you. Below is information on common heart conditions that we treat at West Suburban Medical Center’s cardiac center. 

Acute Coronary Syndrome

Acute coronary syndrome occurs when blood supply to the heart is suddenly blocked. It is a medical emergency and chest pain is its main symptom.


Angina is chest pain that is caused by reduced blood flow to the heart.


An arrhythmia is an abnormal heart rhythm.


Atherosclerosis is the hardening of the arteries due to plaque build-up inside the arteries.

Atrial Fibrillation (AFib)

Atrial fibrillation (AFib) is a quivering, irregular heartbeat that may cause stroke and other heart-related complications.

Cardiac Arrest

Cardiac arrest occurs when the heart suddenly stops working. It is a medical emergency.


Cardiomyopathy is an enlarged heart muscle. As the heart gets larger, it becomes weaker.

Chronic Total Occlusions

A complete blockage in a coronary artery is called a total coronary occlusion, and if the blockage is more than three months old, a chronic total occlusion.

Coronary Artery Disease

Coronary artery disease refers to a buildup of plaque in the arteries of the heart. It can lead to a heart attack.

Heart Attack

A heart attack occurs when blood flow to the heart is dramatically reduced. This loss of blood flow can cause portions of the heart muscle to die.

Heart Block

A heart block occurs when the electrical signal that causes the heart to pump is interrupted or stopped. 

Heart Failure

Heart failure occurs when the heart is significantly weakened so that it can no longer adequately supply the body's cells with oxygen. Fatigue and shortness of breath make everyday activities difficult.

Infective (Bacterial) Endocarditis

Infective endocarditis is an infection of the lining of the heart. It may be caused by bacteria and can lead to complications such as heart valve destruction and congestive heart failure.

Inherited Rhythm Disorders (IRDs)

Inherited rhythm disorders (IRDs) cause irregular heartbeats. IRDs can be managed with medication and other treatments.

Long QT Syndrome (LQTS)

Long QT syndrome (LQTS) is a heart rhythm disorder that may cause rapid, chaotic heartbeats. These rapid heartbeats may lead to sudden fainting, seizure or death.


Pericarditis is the inflammation of the sac that surrounds the heart. 

Peripheral Vascular Disease

Also called PVD or PAD, it occurs when the blood vessels distant from your heart become damaged or blocked. PVD may lead to blood clots, swelling or narrowing and blockage of the blood vessels and other serious concerns.

Rheumatic Heart Disease

Also called RHD, rheumatic heart disease is a chronic heart condition caused by rheumatic fever, which is caused by a strep infection. Treating strep with antibiotics can prevent rheumatic fever.

Valve Disorders

Valve disorders involve problems with the valves that regulate blood flow throughout the heart. In general, valves either harden or leak.
