Cardiology Team

Together the cardiology team works to create comprehensive, individualized treatment plans for each patient. The cardiology team keeps the patient's primary care physician (PCP) informed and up to date on the patient's progress and works with the PCP to create a plan designed to ensure, and continue to improve, the patient's heart health.

Cardiology Services

Cardiology is a branch of medicine which deals with the diagnosis and treatment of the cardiovascular system - heart, arteries, and veins. Hannibal Regional Medical Group's cardiologists treat patients with suspected heart disease by taking a very careful, extensive history of the patient's condition, and performing a complete physical examination.

Risk factors for a Heart Attack include:

There are many risk factors and warning signs for a heart attack. See below for a list of risk factors are genetic and acquired to see what you can do to reduce your chances of having a heart attack. 

Inherited (genetic) factors: Who is most at risk?
  • People with inherited hypertension (high blood pressure)
  • People with inherited low levels of HDL (high-density lipoproteins),high levels of LDL (low-density lipoprotein) blood cholesterol or high levels of triglycerides
  • People with a family history of heart disease (especially with onset before age 55)
  • Aging men and women
  • People with type 1 diabetes
  • Women, after the onset of menopause (generally, men are at risk at an earlier age than women, but after the onset of menopause, women are equally at risk)

Acquired risk factors: Who is most at risk? A heart attack can happen to anyone - it is only when we take the time to learn which of the risk factors apply to us, specifically, can we then take steps to eliminate or reduce them.

  • People with acquired hypertension (high blood pressure)
  • People with acquired low levels of HDL (high-density lipoproteins), high levels of LDL (low-density lipoprotein) blood cholesterol, or high levels of triglycerides
  • Cigarette smokers
  • People who are under a lot of stress
  • People who drink too much alcohol
  • People who lead a sedentary lifestyle
  • People overweight by 30 percent or more
  • People who eat a diet high in saturated fat
  • People with type - 2 diabetes
Managing heart attack risk factors

Managing your risks for a heart attack begins with:

  • Examining which of the risk factors apply to you, and then taking steps to eliminate or reduce them.
  • Becoming aware of conditions like hypertension or abnormal cholesterol levels, which may be "silent killers."
  • Modifying risk factors that are acquired (not inherited) through lifestyle changes. Consult your doctor as the first step in starting right away to make these changes.
  • Consulting your health care provider soon to determine if you have risk factors that are genetic or inherited and cannot be changed, but can be managed medically and through lifestyle changes.

What are the warning signs of a heart attack?

The following are the most common symptoms of a heart attack. However, each individual may experience symptoms differently. Symptoms may include:

  • Severe pressure, fullness, squeezing, pain and/or discomfort in the center of the chest that lasts for more than a few minutes
  • Pain or discomfort that spreads to the shoulders, neck, arms, or jaw
  • Chest pain that increases in intensity
  • Chest pain that is not relieved by rest or by taking nitroglycerin
  • Chest pain that occurs with any/all of the following (additional) symptoms: sweating, cool, clammy skin, and/or paleness shortness of breath, nausea or vomiting, dizziness or fainting, unexplained weakness or fatigue, rapid or irregular pulse
Although chest pain is the key warning sign of a heart attack, it may be confused with indigestion, pleurisy, pneumonia, or other disorders. The symptoms of a heart attack may resemble other medical conditions or problems. Always consult your health care provider for a diagnosis.

Interventional Cardiology at Hannibal Regional

Having 24/7 Interventional Cardiology coverage at Hannibal Regional Hospital is extremely important to Hannibal Regional and to our community. Interventional Cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases.The main advantages of using the interventional cardiology or radiology approach are the avoidance of the scars and pain, and long post-operative recovery. Additionally, interventional cardiology procedure of primary angioplasty is now the gold standard of care for an acute myocardial infarction. It involves the extraction of clots from occluded coronary arteries and deployment of stents and balloons through a small hole made in a major artery. For more information call 573-248-1300 .Non-invasive cardiologists provide expertise in the detection and treatment of heart disease. Non-invasive cardiology involves tests to evaluate and diagnose disorders of the heart. A person with a history of heart disease, chest pain with unknown cause or valvular heart disease may be referred for non-invasive evaluation, including:

Cardiac Stress Testing - Electrocardiographic (EKG) examination of the heart at rest and at various levels of exercise. May reveal abnormalities of the blood supply to the heart muscle and/or abnormalities of the heart rhythm not seen at rest. May be performed on a treadmill or an IV drug may be administered to simulate the heart at exercise. Often performed in conjunction with Nuclear Cardiology or the Stress Echo. 
Cardioversion - A procedure used to convert an irregular heart rhythm to a normal heart rhythm by applying electric shock or using certain medications.

Coronary Computed Tomographic Angiography:  Coronary Computed Tomographic Angiography - (64 slice CCTA) is a new, state-of-the-art, non-invasive, diagnostic tool that visualizes the myocardium (heart), aorta, lungs and coronary circulation and may dramatically alter the way cardiac and vascular diseases such as coronary artery disease (CAD), dissections and aneurysms of the aorta, and atrial fibrillation are diagnosed, evaluated and treated. 

Doppler Study - A diagnostic study using special tool that detects the presence or absence of flow in blood vessels through the skin. 

ECG or EKG - Electrocardiogram - A test that records the electrical activity of the heart muscle and rhythm, usually done while the patient is lying down at rest. 

Echocardiogram - Use of high frequency sound waves to visualize continuous blood and heart movements. 

Event Monitoring - A small recording device, worn for up to 30 days while the patient performs their normal daily activities. When the patient experiences a symptom (or "event") that might be heart related, the patient activates a memory record button on the device. Then the device will typically store the heart rhythm that occurred 45 seconds before and 15 seconds after the record button press. The device's memory is then downloaded for the physician to examine. 

Head Up Tilt Table (HUTT) Test - Test performed on a table that "tilts" the patient from a supine to standing position for various periods of time. Ordered by the physician to determine if near syncopal/syncopal (fainting) episodes might be related to cardiovascular causes. 

Holter Monitoring - A small device, worn by the patient while the patient performs their normal daily activities. The device provides continuous recording of the electrical activity of the heart for 24 hours or more to determine abnormalities. 

Nuclear Cardiology/Nuclear Stress Testing - Imaging of the heart at work (exercise) and at rest using injection of a harmless radioactive tracer(dye) and a gamma camera that produces comparative pictures of the blood supply to the heart muscle at work and at rest. May be performed on a treadmill or an IV drug may be administered to simulate the heart at exercise. 

Stress Echocardiography - High frequency sound wave image of the moving heart, done at rest, followed by imaging after exercise on a treadmill or after an IV drug has been administered to simulate the heart at exercise. 

Transesophageal echocardiography (TEE) - A diagnostic test, using a special probe placed within the esophagus, that employs ultrasound waves to make images of the heart chambers, valves and surrounding structures.
