Cardiovascular Medicine
Welcome to the Department of Cardiovascular Medicine at Insight Chicago Hospital and Medical Center! It is our privilege to bring back critical cardiology services to the Bronzeville community.  Taking care of your heart is one of the most important things you can do to improve your overall health and well-being. 

When taking care of your heart, it is important that we take a holistic view that incorporates your family history, lifestyle, and risk factors for heart disease. 

Being heart healthy means eating right, regular exercise, and taking appropriate steps to manage conditions like high cholesterol, high blood pressure, and diabetes. 

We are excited about the range of services we are able to offer our patients, right here in the community.  Our cardiologists are experts in the management of common conditions like high cholesterol and high blood pressure (hypertension), but also are able to care for your more complex cardiac needs. 

Our areas of expertise in cardiac care include the following: 

  • Arrhythmias (abnormal heart rhythms) like atrial fibrillation or supraventricular tachycardia (SVT) 
  • Coronary Artery Disease (CAD)
  • Heart failure 
  • Hypertension (high blood pressure)
  • Lipid (cholesterol) management
  • Peripheral Artery Disease (PAD)
In order to diagnose and manage these conditions, we are pleased to be able to offer the following imaging, testing, and procedures: 

  • Echocardiography (ultrasound of the heart), including 3-D echocardiography
  • Transesophageal Echocardiography (special ultrasound of the heart used to obtain better images), including 3-D TEE
  • Stress testing (including stress echo, nuclear stress testing, and regular treadmill testing)
  • ABIs and both arterial and venous duplex ultrasounds to evaluate for peripheral artery disease (PAD)
  • Cardioversions (procedure that can help restore normal rhythm)
  • Diagnostic cardiac catheterization and interventions (for example, placing stents to open up blockages)
  • Peripheral artery diagnostic angiograms and intervention
