Heart Health Testing

Heart testing is an essential aspect of maintaining long-term health and wellness. These tests offer a window into your cardiovascular health, helping to identify vulnerabilities or issues before they develop into serious complications. Regardless of age, lifestyle, or family history, everyone can benefit from regular heart screenings. Early detection is crucial in effectively managing and treating heart conditions, potentially saving lives. In addition to guiding treatment plans, these tests can motivate individuals to adopt healthier habits, offering a tangible measure of the benefits of lifestyle changes like diet and exercise. By incorporating heart tests into routine healthcare, people are better equipped to take proactive steps to safeguard their heart health. To better understand why we need heart testing and what each test does, let's go over some common Cardiovascular tests. 


An Electrocardiogram (EKG or ECG) is a diagnostic tool that measures and records the electrical activity of the heart over a period of time. It's a non-invasive procedure that involves attaching a series of electrodes to the skin on the chest, arms, and legs. The ECG provides essential data in real-time, capturing the heart's rhythm and rate to generate a graphical representation. EKGs are commonly performed to investigate symptoms like: 

  • Chest pain 
  • Palpitations 
  • Shortness of breath
  • Routine check-ups, especially for those with risk factors like high blood pressure, high cholesterol, smoking, or a family history of heart disease. 
  • EKGs are also done before surgeries to evaluate heart function and assess the potential risks associated with anesthesia and the procedure itself. 

Electrocardiograms are particularly useful for identifying irregularities in heart rate and rhythm, which can be symptoms of conditions like arrhythmias, heart attacks, or other heart-related issues. Moreover, an EKG can show evidence of past heart events, such as a prior heart attack, and can help determine whether the heart is receiving enough oxygen. By providing this valuable information, an EKG allows healthcare providers to make informed decisions about further diagnostic tests or treatment plans. 


An echocardiogram is a diagnostic imaging test that employs ultrasound technology to create detailed pictures of the heart's structure and function. Unlike an EKG, which primarily records the electrical activity of the heart, an echocardiogram provides a visual insight into the anatomy and mechanical operations of the heart. It's a non-invasive procedure where a transducer, a device that emits high-frequency sound waves, is placed on the chest to generate images of the heart. Echocardiograms are often performed when there are symptoms like: 

  • Shortness of breath
  • Chest pain
  • Irregular heartbeats
  • Monitoring the progress of known heart disease
  • Evaluating heart function before surgical procedures

If you have risk factors such as high cholesterol, high blood pressure, or a family history of heart issues, an echocardiogram might be recommended as part of your preventative care. The echocardiogram can identify various heart conditions, including: 

  • Heart valve diseases 
  • Congestive heart failure
  • Cardiomyopathies
  • Size and shape of the heart
  • Effectiveness of the heart valves and chambers
  • Velocity of blood flow
  • Fluid detection around the heart 
  • Blood clots 
  • Tumors 

Cardiac Stress Test 

A cardiac stress test, also known as an exercise stress test, is a diagnostic procedure designed to evaluate how well your heart performs during physical exertion. Unlike resting heart tests like EKGs or echocardiograms, stress tests measure the heart's capability under an artificially induced "stress" environment, usually through exercise on a treadmill or stationary bike. In some cases, medications may be used to mimic the effects of exercise if the patient is unable to engage in physical activity. The test is often recommended for individuals who exhibit symptoms like: 

  • Unexplained chest pain
  • Shortness of breath
  • Irregular heartbeat

Cardiac stress tests are also useful for those with certain risk factors such as high blood pressure, high cholesterol, or a family history of heart disease. Additionally, a cardiac stress test can be prescribed for people who are already diagnosed with a heart condition or have undergone heart surgery to gauge the effectiveness of their treatment and determine a suitable exercise regimen. During the test, electrodes attached to your chest monitor your heart's electrical activity while blood pressure and other vital signs are continuously measured. The level of exercise or medication is gradually increased to put the heart under increasing stress, mimicking the effects of physical or emotional stress that could trigger a cardiac event. The cardiac stress test provides valuable information on the overall condition of the heart. It can identify irregular heart rhythms, insufficient blood flow to the heart, and other conditions that might require further investigation or immediate treatment.

Coronary Angiogram 

A coronary angiogram is a specialized procedure used to get detailed X-ray images of the heart and its blood vessels. This test is especially useful for assessing the presence and severity of blockages in the coronary arteries, which are responsible for supplying blood to the heart muscle. The procedure often involves the use of a contrast dye, which makes the coronary arteries visible on the X-ray images. Coronary angiograms are generally recommended for individuals: 

  • Experiencing symptoms of coronary artery disease, such as chest pain or shortness of breath.
  • For those who have had abnormal results from other heart tests like an EKG or stress test. 
  • Individuals who have had a heart attack or are at high risk of one.

Essentially, this test offers a direct look into the vessels of the heart, something that non-invasive tests cannot provide. What sets the coronary angiogram apart is its ability to directly visualize the inside of the arteries, offering precise information about blockages or narrowing that may be occurring. It can guide interventional procedures like angioplasty or stent placement and can be instrumental in planning surgeries like a coronary artery bypass graft (CABG). Importantly, the test can determine the extent and location of arterial plaque, providing valuable information that helps in forming a targeted treatment plan. A coronary angiogram is a crucial diagnostic tool for individuals with suspected or confirmed heart issues. It offers the kind of detailed visual information about the heart's blood vessels that most other tests can't provide, making it essential for both diagnosis and treatment planning in cardiovascular care.

Heart testing is not just for those who are already experiencing symptoms; it’s an invaluable tool for preventive healthcare, suitable for everyone interested in maintaining their long-term well-being. Heart testing serves as a cornerstone in cardiovascular healthcare, offering invaluable insights into one's heart health. From EKGs that detect electrical abnormalities to echocardiograms that visualize structural issues, each test offers its unique advantages. Cardiac stress tests evaluate heart performance under strain, while coronary angiograms offer an in-depth look at arterial health. Collectively, these diagnostic tools are instrumental for early detection and intervention, aiding in tailored treatment plans. They can literally be life-saving, particularly in cases where time-sensitive decisions are crucial. Undergoing these heart tests can serve as a wake-up call to make beneficial lifestyle changes, thereby adding layers of preventative care. Incorporating heart tests into regular health screenings can empower individuals to take control of their cardiovascular health, ensuring a better quality of life and longevity.
