Coronary Artery Disease Baytown
Heart is a muscular pump. I needs oxygen and nutrients to function properly. Blood vessel that supply oxygen- and nutrient-rich blood to the heart muscle are called coronary arteries.
Coronary arteries are like small pipes and coronary artery disease (CAD) happens when these arteries get narrower due to fatty material or plaque build up inside. This is an aging process and is a lifelong condition. Therefore, many people do not know they have it until it starts causing symptoms.
CAD affects more than 15 million American adults, making it the most common type of heart disease.
The American Heart Association (AHA) estimates that someone in the US has a heart attack about every 40 seconds. In addition, for patients with no risk factors for heart disease, the lifetime risk of having cardiovascular disease is 3.6% for men and less than 1% for women. Having 2 or more risk factors increase the lifetime risk of cardiovascular disease to 37.5% for men and 18.3% in women.
CAD is sometimes called atherosclerotic heart disease or coronary heart disease.
Intially, as the plaque builds up in the coronary arteries, many people have no symptoms at all. However, if these plaques rupture, they can cause heart attack in otherwise asymptomatic people.
Over the years, as the plaque build up continues, significant blockage of the artery (70 percent or more) can develop. This may cause the following symptoms:
- Chest pain
- Pain in the arms or jaw
- Shortness of breath
Dr. Shehzad Sami, a board certified cardiologist in Baytown, first obtains a complete medical history and performs a comprehensive physical exam to assess risk factors, signs and symptoms of established CAD or to obtain other clues which help in diagnosis of CAD.
Here at Houston Cardiovascular Institute, we have on-site Laboratory Services for the convenience of our patients. Routine labwork is obtained to check your cholesterol level, sugar, electrolytes, kidney function and thyroid function
Various tests that are used to diagnose CAD include:
- Electrocardiogram (ECG) – Records heartís electrical activity
- Chest X-ray
- Echocardiogram – Ultrasound of the heart. Used to see the cardiac structures and measure function of the heart, known as ejection fraction
- Exercise Treadmill Stress Test – Non-invasively evaluate blocked arteries in the heart.
- Nuclear Cardiac Stress Test
- Cardiac Catheterization or Coronary Angiogram – Examines the inside of heart’s blood vessels using special X-rays called angiograms
There are a number of treatment options for CAD, including lifestyle changes, medications, surgery and/or medical procedures.
Dr. Sami may recommend eating a heart-healthy diet, regular exercise, avoiding tobacco smoke, losing weight (if youíre overweight or obese) and managing stress.
Medications include Aspirin or other blood thinners and treatment for high cholesterol, high blood pressure and high blood sugar.
If non-invasive tests are abnormal or symptoms strongly suggest CAD, invasive procedures such as coronary angiogram may be performed with intent to open blocked arteries with a stent, called percutaneous coronary intervention (PCI).
If mutiple arteries are found to be blocked or the blockage cannot be opened with stent placement, then coronary artery bypass surgery (CABG) or open heart surgery may be needed.
After PCI, CABG or heart attack, Dr. Sami strongly encourages his patients to enrol in a 12-week cardiac rehab program. Multiple clinical studies have shown benefecial of cardiac rehab to all cardiac patients.
