Dr. Avalos discusses his training at DHR Health and UTRGV, including his role in the early residency and cardiology fellowship programs, followed by advanced specialization in interventional cardiology in Michigan before returning to serve patients in the Rio Grande Valley. Dr. Avalos explains that interventional cardiologists specialize in diagnosing and treating blockages within the coronary arteries, particularly during emergencies such as heart attacks. Unlike general cardiologists, they perform procedures to quickly restore blood flow when arteries become blocked. Time is critical during a heart attack, and treatment often occurs within a 90-minute window to minimize heart damage. A major focus of the discussion is cardiac catheterization, a minimally invasive procedure that is not considered surgery. During the procedure, a small catheter is inserted through the wrist or groin and guided to the heart. Contrast dye is used to visualize the coronary arteries and identify any blockages, their location, and their severity. This allows physicians to determine the most appropriate treatment plan. When blockages are found, many can be treated immediately with balloons and stents during the same procedure. Balloons are used to open narrowed arteries, while stents—small metal mesh devices that resemble tiny springs—are implanted to keep arteries open permanently. Modern stents often contain medication to help prevent re-narrowing of the artery. Most stent procedures are completed on an outpatient basis, allowing patients to return home the same day. The symptoms of coronary artery disease can vary widely. While chest pressure or tightness are common warning signs, some patients, particularly women, older adults, and individuals with diabetes, may experience atypical symptoms such as indigestion, burning sensations, or symptoms resembling acid reflux. Because heart attacks can present differently among patients, persistent or unusual symptoms should always be evaluated promptly. Several diagnostic tools help evaluate chest pain and assess heart disease risk. An electrocardiogram (EKG) is typically the first test performed in emergency settings. For outpatient evaluation, treadmill stress tests are commonly used to monitor heart function during exercise. Patients who cannot exercise may undergo nuclear stress testing, which provides similar information without physical exertion. The conversation also covers situations where coronary artery bypass surgery may be necessary. While isolated blockages can often be treated with stents, patients with multiple severe blockages, complex anatomy, or disease involving several coronary arteries may benefit more from open-heart bypass surgery. Treatment decisions depend on the number, location, and complexity of the blockages identified during cardiac catheterization. Dr. Avalos emphasizes the importance of prevention and risk-factor management. Maintaining healthy cholesterol levels, controlling blood pressure, managing diabetes, reducing sodium intake, staying physically active, and following a heart-healthy diet can significantly reduce the risk of coronary artery disease, heart attacks, strokes, and heart failure. Regular follow-up with healthcare providers is essential to monitor these risk factors and intervene early when needed.
