Cotton O’Neil Manhattan Cardiology

Why travel out of town when you can get the same great cardiology care in your own community?

Our cardiovascular care is dedicated to making top-class heart care accessible outside of the Topeka region. If you live in Manhattan, Kansas, and surrounding communities, you do not have to travel far to get comprehensive and compassionate care from our cardiologists.

Cotton O’Neil Manhattan Cardiology has multiple services under one roof. We offer lab, imaging, and cardiology services. We perform diagnostic tests such as ultrasound, CT scan, and stress tests, all in one location. This allows our cardiologists to get your test results without delay and answer your questions in a timely manner.

You will have access to the exceptional resources and services while enjoying a more personal approach to care where your provider recognizes you, knows your name, and greets you like a neighbor.

The Cotton O’Neil Manhattan building is also home to Cotton O’Neil primary care providers. This makes it easy for your cardiologist and primary care provider to consult face-to-face and get a full picture of your health condition when creating a treatment plan. They will also be able to receive real-time updates from one another, providing an ultimate total wellness approach to your care.

Conditions We Treat

Cotton O’Neil Manhattan Cardiology treats common and complex heart, artery, and vein diseases. Some of the more commonly treated conditions include:

Heart attack

When your coronary arteries become partially or completely blocked by plaque — a substance composed mainly of fat and cholesterol — not enough blood can pass through and provide oxygen to the heart muscle. Signs of a heart attack can vary from person to person. Don’t wait to see a health care provider if you suspect you have any signs of a heart attack — call 911.

In Manhattan, we provide initial non-urgent and urgent testing and assessment. We can also perform heart catheterizations at Via Christi Hospital, but you may be transferred to Stormont Vail in Topeka for further treatments. You can have your follow-up care in our Manhattan location after treatment at Stormont Vail if you are a patient of Dr. Hurtig or Dr. Katz.


An aneurysm is a bulge that grows in the artery wall. If it bursts, it can cause serious bleeding or even death.

Heart Failure

The heart is a muscle that pumps blood to the rest of the body. Heart failure is a decline in the heart muscle’s ability to function properly. Many factors — such as aging, high blood pressure, and heart attack — can weaken your heart muscle. Gradually, your heart may no longer be able to keep up. When you have heart failure, you may feel out of breath and tired. While heart failure is chronic and can worsen over time if left untreated, it can be managed with medications and lifestyle changes.

Peripheral Artery Disease (PAD)

Arteries run through your body, and peripheral arteries are ones in your legs, stomach, arms, and head. If your peripheral arteries are narrowed and blocked by plaque, you may feel cramping, pain, and weakness in the legs when walking or climbing a flight of stairs. PAD can reduce your quality of life and increase your risk of heart attack or stroke.

Learn more about peripheral artery disease.

Aortic Stenosis

Your aortic heart valve controls the amount of blood flowing from your heart’s left ventricle (lower left chamber) to your aorta (artery that carries blood to the body). If you have aortic stenosis, your aortic valve can’t open fully and the amount of blood that can pass through the artery is restricted. You may not feel any symptoms until the blood flow is greatly reduced. Over time, you may have:

  • Shortness of breath
  • Chest pain
  • Palpitations
  • Heart murmur

In serious cases, the aortic valve may need to be surgically repaired or replaced. This procedure can be done at Stormont Vail Hospital, a collaborative partner with the Cotton O’Neil Cardiology practice in Manhattan and Via Christi Hospital.

Learn more about aortic valve replacement.

Varicose Veins

Varicose veins appear twisted and swollen as a result of blood pooling in the veins. This may be caused by weak valves within the veins. When the valves are weak, blood may flow backward and collect in the vein. In addition to age, many other factors can increase your risk of developing varicose veins, including:

  • Standing or sitting for too long without a break
  • Being overweight
  • Being pregnant
