Cardiologist Reveals 3 Essential Heart Tests You Need to Know
Heart disease remains a significant health concern, claiming thousands of lives daily in America. With the increasing prevalence of conditions like obesity, high blood pressure, and diabetes, the risk of heart-related complications is on the rise. Dr. Jeremy London, a seasoned cardiothoracic surgeon, is using his platform to enlighten the public on vital heart tests. These tests are crucial for those experiencing heart issues and can offer insights into one’s cardiovascular health. Dr. London emphasizes the importance of understanding these tests as part of your health “toolbox” to gauge your risk.
Echocardiogram
Echocardiograms are a key diagnostic tool for evaluating heart health. Dr. London notes, “This is just like the ultrasounds that are done during pregnancy.” This test is particularly useful for individuals experiencing symptoms such as chest pain or shortness of breath.
The most common type, the Transthoracic echocardiogram (TTE), involves placing a small probe on the chest. This probe sends high-frequency sound waves that bounce off the heart, creating echoes. These echoes are transformed into moving images, allowing doctors to assess valve function and heart strength. Echocardiograms can also detect congenital heart defects, murmurs, and blood flow issues.
Stress Test
The stress test, also known as a cardiac stress test, is another essential screening method. Dr. London describes the process: “You’re placed on a treadmill with EKG pads and then exercised at different levels of exertion, looking for symptoms and changes in your EKG.”
This test is instrumental in diagnosing coronary artery disease and heart rhythm problems. It also evaluates the effectiveness of heart treatments. Tailored to each individual based on factors like age and family history, the stress test lasts about 10 to 15 minutes. It provides valuable insights into heart function and blood flow.
Calcium Score Test
The calcium score test is a noninvasive way to assess the presence of coronary artery disease (CAD). Dr. London explains, “You’re placed in a CT scanner and actual pictures of the calcium burden are recorded.” This test identifies hardened plaque in the coronary arteries, which can lead to blockages.
A buildup of calcium is associated with increased heart attack risk, often without prior symptoms. The test results in a score ranging from zero to 400, indicating the extent of calcium buildup. As Dr. London points out, “You’re given a score from zero to 400, determining whether or not you have significant calcium buildup in the arteries.”
Understanding these heart tests is crucial for anyone concerned about their cardiovascular health. While they need to be recommended by a doctor, Dr. London highlights their simplicity: “These are all noninvasive tests, no needles, no entry into the body.” However, it’s important to remember that each test has its limitations. Consulting with your healthcare provider can help determine which tests are appropriate for your preventative care.
