Nowadays, there has been an increased prevalence of heart disease among Thai individuals, largely influenced by lifestyle choices that heighten the risk of cardiovascular problems. Many are familiar with the term cardiac catheterization and are interested in its role in treating heart disease. What exactly is cardiac catheterization? Why is it necessary? And how does it benefit patients? Furthermore, is there a risk of heart disease recurring after undergoing this procedure? Today, we will explore these questions in detail.
Cardiac catheterization serves both diagnostic and treatment purposes.
To clarify, cardiac catheterization, also known as Coronary Artery Angiography (CAG), is a procedure that can be used for both diagnosing and treating heart disease. During this procedure, a small catheter, about 2 millimeters in diameter, is inserted into the body. The catheter is typically introduced through an artery in the groin, wrist, or the bend of the arm, and is then guided up to the aorta near the heart.
If the procedure is for diagnostic purposes, a contrast material is injected into the blood vessel, allowing an X-ray to reveal any narrowing, stenosis, or blockages in the coronary arteries. If a blood clot or blockage is detected, the doctor will determine the appropriate treatment. This could involve performing a balloon angioplasty (Percutaneous Transluminal Coronary Angioplasty – PTCA), where a stent is inserted to open the blocked artery and improve blood flow, or opting for coronary artery bypass surgery (CABG), which reroutes blood flow around the blocked area.
When should you consider an examination?
Cardiac catheterization is typically recommended for individuals experiencing the following symptoms:
- Acute chest pain, possibly radiating to the jaw or arm
- Worsening or more frequent chest pain
- Shortness of breath, chest tightness, or unusual fatigue
- Individuals with abnormal results from other medical tests, such as an ECG, an exercise stress test (treadmill test), or a cardiac ultrasound (echocardiogram), which may suggest a risk of heart disease.
Preparation Before the Examination
Before undergoing a cardiac catheterization procedure, it’s important to inform your doctor about your medical history, including any drug or food allergies and existing medical conditions. Additionally, you should provide details about any medications you are currently taking so that your doctor can determine which ones should be continued or discontinued prior to the procedure.
Post-Procedure Care After Cardiac Catheterization
Cardiac catheterization is a minimally invasive procedure, allowing for a short recovery period of just 1-2 days in the hospital. If no complications arise, patients can continue their recovery at home. However, it’s important to avoid strenuous activities for the first 7 days after the procedure. Additionally, staying well-hydrated by drinking plenty of water is recommended during this time. Following up with your doctor is very important. During these visits, the doctor will assess the condition of your heart and blood vessels and provide guidance on lifestyle changes. These may include weight loss, regular exercise, eating a nutritious diet, and avoiding smoking and alcohol. These steps are essential to prevent the recurrence of heart disease.
Advantages and Considerations of Cardiac Catheterization
Cardiac catheterization is an effective procedure for both diagnosing and treating heart disease. It accurately identifies and addresses narrowed or blocked coronary arteries, helping patients regain a better quality of life. Additionally, it lowers the risk of serious complications, such as heart attacks.
Although cardiac catheterization is a safe procedure, there are still risks and potential side effects that may occur, such as infection, blood clots, or injury to blood vessels. Therefore, patients should consult their doctor to evaluate the risks and benefits before deciding to undergo cardiac catheterization.
Can coronary artery disease recur after treatment with cardiac catheterization?
When treating coronary artery disease with cardiac catheterization, such as inserting a stent or performing balloon angioplasty, there is a possibility that the artery may become blocked again. Factors that influence the likelihood of recurrence include lifestyle behaviors such as smoking and a high-fat diet, existing medical conditions like diabetes and high blood pressure, and self-care practices following treatment.
Recurrent blockage may occur if lifestyle changes are not made. Proper self-care after treatment includes strictly following the doctor’s instructions regarding medications, such as antiplatelet drugs, engaging in regular exercise, and eating a nutritious diet rich in fruits, vegetables, whole grains, and low-fat proteins. Regular follow-up with your doctor to monitor heart and vascular health can help reduce the risk of recurrent blockages and maintain long-term heart health.
Cardiac catheterization is a valuable procedure for both diagnosing and treating heart disease. Individuals experiencing symptoms that indicate a risk of heart disease, as mentioned earlier, should consult a doctor for evaluation and to develop an appropriate treatment plan.
