We offer comprehensive diagnostic tests and advanced treatments for common to complex heart conditions.

What Are Cardiology Services?

Seeing a cardiologist is an important first step when you have a potential heart problem. Your cardiologist often serves as your primary heart doctor, coordinating care with your primary care physician and other heart specialists to address all your cardiac needs.

Our cardiologists:

  • Assess heart disease risk factors
  • Diagnose heart conditions
  • Offer treatments to improve heart function
  • Provide preventive care to lower the risk of heart disease and related complications

Specialty Cardiology Services

As a regional leader in heart and vascular care, we offer specialized cardiology services, including:

Women’s Heart Care

Women have unique risk factors for heart disease. They also experience cardiac events like heart attacks differently than men. We designed our women’s heart care services to meet the distinct needs of women who have, or are at risk for, heart problems. Our women’s heart services also include:

  • Cardio-obstetrics: Our cardiologists partner with maternal-fetal medicine (MFM) doctors to help women experiencing cardiac-related, high-risk pregnancies.
  • Chest pain clinic: Our advanced screenings help detect microvascular disease, a common, but often overlooked, cause of chest pain in women.

People with cancer can develop heart problems during or after cancer treatments. As part of our cardio-oncology services, our cardiologists partner with doctors at Memorial Cancer Institute. These specialists work together to prevent, and sometimes reverse, cancer-related heart damage.

The team carefully monitors your heart health throughout cancer treatments to quickly identify potential problems and promote a heart-healthy, cancer-free future.

Lynda Otalvaro Orozco, MD - Cardiologist

I am a general cardiologist at Memorial Cardiac and Vascular Institute. I care for patients with a wide variety of heart conditions, which can present and manifest differently for male and female patients. I am also interested in atherosclerotic heart disease (hardening of the arteries) prevention and preventing further events in patients who already suffer from this prevalent condition or are cancer survivors with a high risk of cardiovascular disease.

I am certified in cardiology, echocardiography, nuclear imaging and clinical lipidology, which allows me to evaluate patients with genetic disorders that predispose them to cardiovascular disease at a young age.
