Karen Lewis , MD, Cardiologist

Dr. Karen Lewis is a cardiologist based in Denver with a clinical focus on cholesterol disorders and long-term heart disease prevention. She works with adults who have elevated LDL cholesterol, high triglycerides, or mixed lipid patterns, often in combination with other risk factors such as hypertension, diabetes, or a strong family history of early heart disease.

In her practice, Dr. Lewis starts with a thorough review of lab results, medical history, current medications, and lifestyle habits. Using this information, she designs an individualized plan that may include statins or other cholesterol-lowering medications, as well as realistic changes in nutrition, physical activity, and weight management that are sustainable over time.

Patients appreciate Dr. Lewis’s straightforward explanations of what their cholesterol numbers mean and how improving them can reduce the risk of heart attack and stroke. She provides clear instructions on when and how to take each medication, which side effects to monitor, and when to repeat blood tests. She also emphasizes regular follow-up to adjust treatment as needed and to track long-term progress.

By combining evidence-based cholesterol therapy with practical lifestyle guidance and consistent monitoring, Dr. Lewis helps patients move toward healthier lipid levels, lower cardiovascular risk, and greater confidence in managing their heart health.
