Some issues Dr. James T. Maddux JR., MD can help you with:

Heart Attack

A heart attack is a serious medical event that happens when the blood supplying oxygen to the heart is cut off, usually because of a blockage in an artery. This results in damage or death of part of the heart muscle. The heart can heal, but like any part of the body that was injured it leaves a scar. This scar tissue does not contract effectively, so the ability of the heart to pump is lowered after a heart attack.

A heart attack, sometimes called a myocardial infarction, can happen without warning. However there are certain factors that raise the risk of heart attack. Some of these are:

Age
Gender (most heart attack sufferers are male)
A family history of heart attacks
Smoking
Obesity
High cholesterol
High blood pressure
Diabetes
Unhealthy lifestyle choices (lack of exercise, poor diet, too much alcohol or stress)

Heart attacks typically feel like pain or pressure in the chest that can radiate out to the back, arm, or jaw. Some other symptoms can include fatigue or weakness, shortness of breath, sweating, and nausea.

Treatment aims to increase blood flow to the heart muscle by opening up blocked blood vessels. Medications are sometimes used to dissolve clots in the arteries. Aspirin and other medications such as Plavix can thin the blood and make clots less likely to form. Dilators can widen blood vessels to make room for more blood to flow. Doctors can also use a procedure called catheterization to look at the blood vessels around the heart directly, place stents, or widen vessels using angioplasty. In extreme cases bypass surgery can be used to help blood flow better. After recovery, it is important to lead a healthy lifestyle and take any prescribed medications in order to protect the heart.

Heart Problems

The heart is one of the most important organs in the body. This smooth muscle expands and contracts rhythmically an entire lifetime, pumping blood to the lungs and then to every other cell in the body. When heart problems occur, it becomes difficult for the body to get the nutrients and oxygen it needs via the blood. So while there are a variety of illnesses and disorders that affect the heart, most of them cause weakness, exhaustion and shortness of breath. The most common heart conditions include heart disease, angina, arrhythmia, and valve disorders.

Heart disease is the leading cause of death in the United States for both men and women. This includes coronary artery disease, heart attacks, congestive heart failure, and congenital heart disease. Some conditions, such as genetics, cannot be controlled. But there are many other things one can do to lower their risk for heart disease. Controlling high blood pressure and cholesterol levels, reducing or stopping smoking, exercising more and losing weight if needed, and eating a diet low in sodium can all protect the heart.

Angina is a squeezing type of chest pain that happens when the muscles around the heart don't get enough oxygen. It can be regular or infrequent. Usually, angina is caused by coronary heart disease. However, not all chest pain is angina. Chest pain can also be caused by a lung infection or panic attack, for example, so it is important to have any sudden pain checked.

Arrhythmia is the word for when the heart beats too fast, too slow, or irregularly with skipped beats. It can feel frightening, and depending on the type it can be dangerous, but in most cases arrhythmia is not serious and can be treated. It is very common, especially in older adults.

Heart valve problems can happen in any one of the the heart's four valves that keep blood flowing where it needs to go. Babies can be born with problems in their heart valves, or valves can be damaged by infections. The valves can stiffen and become less mobile, or they can stop closing properly and 'leak' when the heart beats. Valve problems can usually be repaired surgically.

Percutaneous Left Atrial Appendage Closure (LAAC)

Percutaneous left atrial appendage closure (LAAC) is a device implantation procedure that reduces the risk of stroke for patients who have atrial fibrillation, a condition in which the heart beats out of rhythm. Atrial fibrillation causes blood to collect in the left atrial appendage, a small sac located in the top left chamber of the heart. The blood that collects in this appendage can form clots and cause stroke when pumped out of the heart.

To implant the device, a long, flexible tube, called a catheter, is inserted into a large vein in the groin and advanced to the heart. Once the tube reaches the left side of the heart, X-ray is used to guide a thinner catheter into the left atrial appendage. The tiny device is then passed through the tube and into the appendage. When the doctor has made sure it is in the right place, she takes the catheter out, and the procedure is completed.

This minimally invasive procedure usually requires a hospital stay of at least one day. Normal activities may be resumed within a few days. About 45 days following implantation, a test will be done to determine whether the device has closed the left atrial appendage. Check-ups have to be performed every year to make sure the device is in place.

My appointment with Dr Maddux was one of the best Dr appointments I have ever had! He explained everything to me throughly and listened to my concerns. He spent time with me and validated my concerns. He assured me that I would be taken care of and that we would find answers to my medical issues. Dr Maddux is a wonderful doctor and human. I am so glad that he is my doctor. I can't thank him enough for helping me.

The Heart Institute saved my life in 2018 with my quadruple bypass surgery. Dr. Maddox recommended a stress test in October. This was great preventative care which resulted in angioplasty surgery and placement of a stent in a partially blocked artery which probably prolonged my life. I'm very thankful for the great care I have received from Dr. Maddox and the Heart Institute.

THANK YOU!!!

Dr Maddux was recommended to me, and I'm so glad that he was. His knowledge of my condition, concern for ruling out all other possible health concerns and his bedside manner were phenomenal. His whole team that I saw last Friday were so nice to sit down with, and all of my questions were answered (from weeks prior to the day of the appt ).

I had a very good experience with Dr. Maddux this last time, as I had an appointment a couple of hours after my husband's appointment with him and he was able to see immediately after he was through seeing my husband. One of his nurses arranged this, and both my husband and I were very appreciative of it.

Dr. Maddox was very nice and was so helpful to me. The only problem I had was they ran a couple more blood tests and said they would contact me about the results. That did not happen. I sent a message through MyChart asking for clarity on these tests but did not get any response.

All of the people involved are great. The Doctor, nurses, receptionists, and even the insurance verification people. They all treat the patient with the utmost respect. They are very good at returning phone calls & keeping you informed about your case, even long distance.

My provider is a very good communicator who explained procedures very thoroughly and showed me samples that were very helpful in understanding details. Took the time needed to answer my questions and ensure I understood. Thanks!

He made sure I understand what the procedure would be and what I would need to know about what to be aware of after. He made me feel comfortable with the medication and what they were doing for me. Easy to talk to and understand
