FAQs: Patient Questions for Dr Dimitrios Koudoumas

Do I really need a stent or angioplasty?

Not always. Dr Dimitrios Koudoumas reviews each angiogram and stress test to determine whether medications, lifestyle changes, a stent or bypass surgery is the best treatment. Dimitrios Koudoumas explains every option so patients can make a confident, informed choice.

Are medications the only way to lower cholesterol?

No. Medication such as statins and aspirin can help, but diet, exercise, weight management and blood pressure control also lower cholesterol and stroke risk. Dr Dimitrios Koudoumas works with your primary care physician and cardiology colleagues to build a prevention plan that fits your life.

What is causing my chest pain and palpitations?

Chest pain and palpitations can come from many causes, from anxiety to coronary artery disease or a heart valve problem. A stress test, imaging and diagnostic testing at Benefis Health System help Dimitrios Koudoumas find the cause and guide the right treatment for each patient.

How does a carotid stent reduce stroke risk?

A carotid stent opens a narrowed carotid artery so that plaque cannot block blood flow to the brain. Dr Dimitrios Koudoumas performs carotid stent and carotid revascularization procedures to reduce stroke risk and help prevent stroke in patients with carotid artery disease.
