Who are cardiologists?
These are professionals who specialize in diagnosing and treating heart and blood vessel disorders, commonly known as cardiovascular diseases (CVDs). They train to address various irregularities, such as arterial blockages, valvular malfunction, heart anomalies, and other conditions.
What is the cardiovascular system, and what are its components?
The cardiovascular system is composed of the heart, blood vessels, and blood. While the heart pumps blood to the body, the blood vessels help this process by delivering and returning blood to and from the heart. This network supplies blood to the various parts of the body and consists of arteries, veins, and capillaries. Blood enters the heart through the veins and leaves through the arteries. The capillaries are tiny vessels that deliver blood from the arteries to all the body tissues.
The body consists of two blood circulatory systems, the systemic and pulmonary circulatory systems. The systemic circulatory system is the primary blood circulatory system because it delivers blood to the body's tissues, organs, and cells. On the other hand, the pulmonary circulatory system transports blood between the lungs and the heart. This is how oxygen enters the blood, and carbon dioxide exits the blood.
What does the heart consist of, and how is oxygen pumped into the blood?
The heart has four chambers – each of the two upper chambers is called an atrium, and the two lower chambers are called ventricles. A septum wall separates the ventricles and atria; valves control the blood flow between these chambers. Blood enters the heart from the right atrium or upper right chamber and then passes to the right ventricle or the lower right chamber. The blood then passes through the lungs, where it receives oxygen. The carbon dioxide exits at the same time. The oxygen-rich blood is pumped back to the heart’s left atrium or upper left chamber and then to the lower left chamber or ventricle. From here, the aorta or large artery delivers the oxygen-rich blood to the body.
What are the different kinds of diseases that a cardiologist can treat?
Cardiologists can treat many heart and vascular disorders. These include myocarditis, congenital conditions (illnesses beginning at birth), blood clots, and atherosclerosis. They can also treat cardiogenic shock, endocarditis, cardiomyopathy, problems with the aorta (stenosis, aneurysm), and stroke. Further, heart doctors can treat issues with the arteries, such as peripheral artery disease, renal artery disease, coronary artery disease, and subclavian artery disease.
Educational background of cardiologists
Cardiologists undergo a rigorous training program that includes four years of medical school. Medical school is followed by three years of residency, focusing on internal medicine. They then complete three years of specialized training at a hospital.
To become a licensed cardiologist, they must clear the cardiovascular disease examination held by the American Board of Internal Medicine (ABIM).
Types of cardiology
There are three broad categories of cardiology - invasive, non-invasive, and interventional. Invasive cardiology is where open surgery or minimally-invasive procedures treat problems with the heart structure. Examples of invasive cardiology include angioplasty and stenting.
With non-invasive cardiology, diagnosing heart problems without inserting foreign objects such as fluids, needles, and other instruments into the body is possible. Examples of non-invasive techniques used by cardiologists include echocardiography, nuclear cardiology, heart monitors, stress tests, CT scans, and cardiac electrophysiology. The test results can help heart doctors diagnose disorders and determine treatment.
Interventional cardiology is a non-surgical method where a catheter repairs parts of the heart structure, such as narrowed arteries and damaged or weakened blood vessels. This technique can treat peripheral, heart valve, and coronary artery disease.
Apart from these three types of cardiology, heart doctors can further subspecialize in the following ways:
- General cardiologist: These cardiologists focus on preventing, diagnosing, and managing cardiovascular diseases. They prescribe medications, provide post-surgery care, and help patients manage heart-related conditions. They are often involved in long-term inpatient care. However, general cardiologists do not receive training to diagnose complex conditions. You may visit a general cardiologist near you if you experience shortness of breath, fluttering sensation in the chest, dizziness, or chest pains.
- Interventional cardiologist: Interventional cardiologists receive advanced training to perform various procedures, such as removing plaque build-up and balloon angioplasty. They can use the latest tools and equipment, such as lasers and cutting devices, to perform the procedures. They treat various conditions, ranging from aortic stenosis and angina to heart attacks.
- Electrophysiologist: Electrophysiologists help treat patients with heart rhythm abnormalities or cardiac arrhythmias. They receive training to perform invasive procedures to help manage these abnormalities. Arrhythmias are electrical abnormalities that can occur due to heart disease. However, it can also occur in normal hearts and affect patients of all ages. Electrophysiologists provide various treatments, from cardiac ablation and medications to advising lifestyle changes. They can also implant cardiac defibrillators and pacemakers to help patients prevent sudden cardiac death and improve heart function.
- Adult congenital cardiologist: These cardiologists receive training to help patients manage genetic heart disorders. They generally provide non-invasive medical treatments but can also offer interventional or invasive treatments. Adult congenital cardiologists provide specialized and ongoing care throughout adulthood. Moreover, they can detect early signs of heart problems and prevent complications.
- Heart failure and transplant cardiologist: These specialists help treat patients diagnosed with heart failure when the heart cannot pump enough blood throughout the body. They provide long-term care to help reverse or stabilize the condition. Accordingly, they can transplant a new heart if your current heart is damaged or failing. Generally, people get heart transplants when they have congenital heart defects or develop severe coronary artery disease.
Preparing for your first appointment with a cardiologist near you
Being prepared beforehand will help you make the most of your visit to a cardiac specialist. Set off early on the day of your appointment so you have enough time to get there and complete the paperwork before you meet the doctor. It also gives you sufficient time to find a parking spot or seek directions if you need help.
You should dress in loose, comfortable clothing as you may have to remove your shirt, shoes, and socks at the doctor's office or wear a gown. Try not to use any body lotion or cream ahead of your appointment. It can cause problems if your doctor wants to run an echocardiogram test that involves sticking sensors to your skin.
It would also be advantageous to bring a family member or friend to the appointment. They could assist you in taking notes and reminding you of symptoms or episodes to describe to your doctor.
Procedures performed by a cardiologist
On your first visit to a cardiologist near you, they will generally note your family history, lifestyle patterns, weight, age, gender, chronic conditions, and several other aspects. After the initial assessment, which may include blood tests and chest X-ray, they could recommend the following procedures to determine the cause of discomfort and subsequent treatment plan:
- Echocardiogram: An ultrasound test that can reveal disorders like cardiomyopathy (a hereditary heart muscle disorder), valvular diseases, and other conditions by tracking the structure and functioning of the heart is called Echocardiogram.
- Electrocardiogram (ECG): An ECG is a diagnostic process that uses temporary electrodes on your chest and limbs to monitor and document your heart's electrical activities.
- Cardiac catheterization: In this invasive diagnostic test, the doctor puts a catheter (pipe-like device) through your arms or groin and maneuvers it to your coronary arteries. The images can reveal inconsistencies in your heart.
- Stress test: It is a non-invasive test requiring running on a treadmill or a walker with an ECG monitor fixed to your chest and arms. It helps monitor your heart's performance during heavy activities.
- Computer Tomography (CT) angiogram: A CT angiogram is an imaging diagnostic test that helps your cardiologist view your blood vessels and tissues by injecting a contrast dye and a specialized X-ray.
- Cardiac MRI: Pharmacological cardiac Magnetic Resonance Imaging (MRI) helps understand the blood flow to your heart.
- Cardiac monitor: A Holter monitor is a device you carry for 24-48 hours while doing regular activities. This test can throw up an irregular heartbeat that your ECG test didn't reveal.
What are the general risk factors for cardiovascular diseases?
Several factors can trigger heart disease. Some are not in our control (non-modifiable), like gender, hormonal issues such as menopause, old age, and family history of cardiac problems. However, we have significant control over others or the influencing (modifiable) factors like :
- Obesity: Being obese or overweight puts us at risk of heart ailments.
- Lack of exercise: Leading a sedentary life, even if you are not overweight, can reduce the efficacy of your heart.
- Unhealthy diet: Excessive junk food, lack of vegetables and fruits in your diet plan, etc., can trigger heart problems.
- Smoking: Cigarettes are a nemesis to a healthy heart. Smoking can cause irreparable damage to your arteries and lead to heart failure or heart attack.
- Alcohol abuse: While some studies suggest that a low-to-moderate intake of alcohol can reduce the chances of CVDs, excessive consumption can trigger several adverse conditions, leading to heart problems.
- High cholesterol: Though there could be genetic influences in some cases, a balanced lifestyle can mitigate the risk of high cholesterol.
- Stress: Financial, relationship, or work-related mental stress can damage the heart significantly. Unwinding and de-stressing activities can make you rejuvenated and healthy.
- Hypertension: Many conditions can often result in high blood pressure or hypertension. Consuming a healthy diet, engaging in regular exercise, managing weight, and taking timely medication can keep it under check.
Tips for a healthy heart
A balanced diet is vital in maintaining a healthy heart and should include liberal amounts of whole grains, fruits, vegetables, and nuts. Eating lean protein, such as fish, chicken, and soy, and moderate amounts of complex carbohydrates, such as starch-free rice, pasta, and whole-wheat bread, would be beneficial. Reducing salt intake and having sufficient water and fluid is also essential.
Cutting down on fatty and oily food, having unsaturated fat instead of saturated fat, and limiting your intake of red meat and simple carbohydrates, like sugar, cookies, baking soda, etc., help maintain your overall health.
