What is cardiology, and who are cardiologists?
Cardiology is the medical subspecialty that focuses on treating and diagnosing various conditions and disorders related to the heart and the cardiovascular system. The cardiovascular system is responsible for processing oxygen and nutrients into the bloodstream, making cardiologists heart and blood vessel experts.
What are the educational qualifications of a cardiologist?
To qualify as a cardiologist in the United States, aspirants complete medical school and undergo three years of residency in internal medicine, followed by another three years of specialized training in cardiology.
A cardiologist can be certified by the American Board of Internal Medicine after ten years of training. With this education, they can treat chest pain, high blood pressure, and problems with blood vessels. They can order diagnostic tests such as electrocardiograms, echocardiograms, and Computed Tomography (CT), and their treatment plan may include medications, health advice, and cardiac catheterization.
Some cardiologists choose to work in more specialized areas of heart care, such as treating congenital (from birth) conditions, heart failure, and heart rhythm problems. You may see cardiologists in affiliated hospitals or private offices where they see patients.
What conditions do cardiologists treat?
Physicians specializing in cardiology can treat various diseases and ailments related to the heart and the cardiovascular system. Here are some conditions that cardiologists treat:
- Heart attacks - A myocardial infarction or a heart attack occurs when a part of the heart muscle is not getting enough blood. A severe coronary artery spasm may cause low or decreased blood flow. Heart attacks require urgent medical attention.
- High blood pressure—Hypertension is an extreme health ailment that can potentially result in heart and cardiovascular issues, such as stroke and heart attack. There aren't many signs or symptoms that indicate a person's blood pressure levels, and to find out if they have high blood pressure, they must get tested. In addition to cardiovascular diseases, hypertension can also result in kidney disorders.
- Heart valve disease - The heart comprises four valves that ensure your blood flows in the right direction. One or more valves cannot function correctly if a person suffers from heart valve disease. Problems with the valves can also lead to the destruction of blood flow.
What types of tests does a cardiologist perform?
A cardiologist has the authority to request the following tests, although certain healthcare providers may also conduct some of these examinations:
- Cardiac catheterization - Cardiac catheterization, or cardiac cath or coronary angiogram, is an invasive imaging procedure designed to assess heart function. In this procedure, a healthcare provider inserts a catheter (a small tube) into a blood vessel, typically in the arm or groin, and advances it into the coronary arteries.
- Heart catheterization allows providers to identify issues and, in some instances, address them through additional procedures often performed during the same appointment.
- Chest X-ray - A chest X-ray uses a concentrated radiation beam to examine the heart, lungs, and bones. Healthcare providers employ this imaging technique to identify and address conditions such as pneumonia, emphysema, or COPD. Chest X-rays are swift and noninvasive, with results typically available within one to two days.
- Cardiac MRI (magnetic resonance imaging) - This method generates detailed images of structures inside the body using powerful magnets and radio frequencies. A healthcare provider might recommend an MRI of the heart to examine the heart valves and major vessels, identify coronary artery disease and its extent of damage, evaluate congenital heart issues, and detect tumors or other abnormalities.
- Cardiac CT (Computed tomography) - Cardiac CT imaging involves using an X-ray machine and a computer to generate three-dimensional pictures of the heart. Sometimes, a dye is injected into a vein to visualize the heart arteries. Medication may also be administered to lower the heart rate, improving image capture. This technique can also assess the amount of calcium in the heart arteries, indicating coronary artery disease.
- Electrocardiogram (ECG): This modality examines the heart's electrical activity, revealing irregular rhythms (arrhythmias) and occasionally identifying heart muscle impairment.
- Stress tests - This procedure, also known as a treadmill or exercise ECG, involves monitoring the heart while walking on a treadmill. Simultaneously, your healthcare provider monitors breathing and blood pressure. A stress test is conducted to identify coronary artery disease or determine safe exercise levels post-heart attack or heart surgery. Exercise can sometimes exert stress on the heart before the test.
- Occasionally, the stress test may include collecting ECG information and heart ultrasound images, known as an exercise or stress echocardiogram, which offers increased sensitivity and specificity compared with ECG stress testing alone.
- Echocardiogram—An echocardiogram is a noninvasive procedure that utilizes sound waves to evaluate the chambers and valves of your heart and its pumping efficiency. Real-time images are generated on the monitor by directing ultrasound waves with a probe across the skin over your heart.
- Transesophageal echocardiogram (TEE)—This procedure resembles a transthoracic echocardiogram but involves administering medication to induce relaxation (sedation). It is categorized as invasive because it requires the insertion of a probe into the body.
- Holter monitor - In this test, you utilize a compact, battery-powered ECG machine. Small patches with wired electrodes are affixed to the skin over your heart. The monitor captures heartbeats continuously for 24 to 48 hours while you engage in regular activities.
- Once this period concludes, you return the monitor to the provider's office for analysis and evaluation. Some Holter monitors can be worn for an extended period of up to 2 weeks, and these monitors come in patch form, eliminating the need for wires.
What are some signs of an unhealthy heart?
You must see a cardiologist near you if you have pain in your chest, dizziness, or shortness of breath. While your primary care provider would refer you to a cardiologist for specialized care when necessary, you may also seek medical attention if you notice unusual symptoms. Some signs that you may have an unhealthy heart are:
- Constant chest pains - Chest pains can sometimes occur due to problems like gastric illnesses; however, if chest pains arise daily, it can be a sign of blockages in the arteries.
- High cholesterol levels - This can significantly increase the blockages in the arteries, thus resulting in a higher chance of heart attacks.
- Low vitamin D levels—Vitamin D deficiency may cause cardiovascular problems. It can also result in various other health issues, challenging a healthy lifestyle.
- Low levels of physical activity or no exercise - Low exercise, combined with being overweight or obese, can be a massive indicator of underlying heart diseases and cardiovascular issues.
If you notice these signs, you may speak to your provider or visit a cardiologist for prevention or treatment plans. They would conduct a physical exam and discuss your medical history with you. They would also ask about your family history, as having a family member with heart problems may increase your chances of having a heart problem.
What are some dietary changes that can improve heart health?
Diet plays a pivotal role in ensuring heart health. Here is a list of diet tips to minimize the risk of developing heart disease:
- Add vitamin supplements to your diet. Various studies indicate that vitamin deficiencies can negatively impact heart health and cause multiple health problems. Add daily vitamin supplements to your diet if you suffer from vitamin deficiencies.
- Green or leafy vegetables like kale or spinach are rich in minerals and antioxidants. They can also be a great source of vitamin K, which is essential for healthy arteries.
- Avoid refined carbohydrates, which can potentially increase coronary heart disease. Instead, switch to whole grains like quinoa, brown rice, oats, etc., which are great sources of unrefined carbohydrates.
- Add a serving of berries and avocados for a healthy snack. Berries and avocados are extremely rich in antioxidants, which protect against inflammation or oxidative stress, which can potentially lead to various heart disorders.
What is FACC?
FACC, also known as the Fellow American College of Cardiology, is a society of professional physicians and scientists specializing in cardiovascular problems. It has over 23,000 members from around the world. Scientists or physicians must have dedicated at least 3/4th of their professional activities to the study of cardiology and must have completed their training in cardiology. FACC is considered the highest and most widely acknowledged title for anyone who practices or specializes in cardiovascular care. It has different levels of membership, ranging from fellow to affiliate. Most FACC members are board-certified adult cardiologists, pediatric cardiologists, and scientists specializing in cardiology and cardiovascular surgery.
Preparing for your first appointment with a cardiologist near you
Here are some tips to make your first cardiology appointment less stressful and more effective:
- Choose comfortable clothing - Wear loose, comfortable clothes, as you might need to remove shoes, socks, or a shirt for exams. Sometimes, you may be asked to change into a gown. For tests like an electrocardiogram (EKG) requiring sensors on your skin, avoid applying lotions beforehand to ensure the sensors adhere correctly.
- Bring a support person - Consider having a friend or family member accompany you. They can help by listening, taking notes, and reminding you of any specific symptoms or concerns. This approach benefits both you and your family, as it helps ensure everyone feels informed and confident about the care you’re receiving.
- Arrive ahead of time - Since the first cardiology visit typically lasts around 40 minutes, arriving 15-20 minutes early allows you to complete paperwork and confirm that the office has received your prior test results and insurance details.
At the appointment, a cardiologist will want a complete picture of your overall health, covering details like:
- Other medical conditions you have
- Any allergies
- All medications you’re taking
- Past surgeries or hospital stays
You may be asked about aspects of your health that don’t seem directly related to your heart. The team is interested in understanding your full health profile. Other conditions could influence your heart health, so a comprehensive view helps them provide the best care.
