Heart disease can develop quietly. Some people experience obvious warning signs like chest pain or shortness of breath, while others may notice more subtle symptoms such as fatigue, dizziness, swelling, or difficulty exercising. 

Knowing when something may be wrong and getting the right cardiovascular evaluation can make an important difference in protecting your long-term heart health. 

At Memphis Vein Center in Memphis, Tennessee, board-certified cardiologist Kishore Arcot, MD, FACC, FSCAI, FSVM, RPVI, provides comprehensive cardiovascular care for patients experiencing heart and circulatory concerns. From advanced diagnostic testing to minimally invasive cardiovascular procedures, treatment is personalized around each patient’s symptoms, risk factors, and overall health. 

What Are the Most Common Signs of a Heart Problem? 

Not every cardiovascular condition causes the same symptoms. In fact, some heart problems may produce few noticeable symptoms in their early stages. 

However, you should pay attention to changes such as: 

• Chest pain, pressure, tightness, or discomfort 

• Shortness of breath 

• Unusual fatigue or weakness 

• Rapid, pounding, or irregular heartbeat 

• Dizziness or lightheadedness 

• Swelling in the feet, ankles, or legs 

• Reduced ability to exercise 

• Leg pain or cramping while walking 

• Fainting or near-fainting episodes 

These symptoms don’t automatically mean you have heart disease, but they can be a reason to seek a cardiovascular evaluation. 

Severe or sudden chest pain, difficulty breathing, fainting, or symptoms suggestive of a heart attack require immediate emergency medical attention. 

What Heart and Cardiovascular Conditions Can a Cardiologist Treat? 

Cardiology encompasses a wide range of conditions involving the heart and circulatory system. Understanding some of the most common cardiovascular problems can help you recognize when specialized care may be necessary. 

Coronary Artery Disease 

Coronary artery disease (CAD) occurs when plaque builds up inside the arteries responsible for supplying blood to the heart. 

As these arteries narrow, the heart may not receive enough oxygen-rich blood, particularly during physical activity. This can cause chest discomfort known as angina. 

When significant blockages are discovered, treatment may involve medications, lifestyle changes, or procedures designed to improve blood flow. 

Chest Pain and Angina 

Chest pain is one of the most recognizable symptoms associated with heart disease, but it can have many different causes. 

Heart-related chest discomfort may feel like: 

• Pressure 

• Tightness 

• Squeezing 

• Burning 

• Heaviness 

Angina occurs when the heart muscle doesn’t receive enough oxygen-rich blood. It may become noticeable during exercise or physical exertion and improve with rest. 

Because chest pain can sometimes indicate a serious cardiovascular problem, recurring or unexplained symptoms deserve medical evaluation. New, severe, or persistent chest discomfort requires emergency assessment. 

Heart Rhythm Problems 

Your heart relies on electrical signals to maintain a normal rhythm. 

When those signals don’t function properly, the heart may beat too quickly, too slowly, or irregularly. These abnormalities are known as arrhythmias. 

Possible symptoms include heart palpitations, dizziness, fatigue, shortness of breath, or fainting. 

Certain patients with an abnormally slow heartbeat may benefit from a pacemaker, a small implanted device that helps maintain an appropriate heart rhythm. 

Peripheral Artery Disease 

Cardiovascular disease doesn’t only affect the arteries surrounding the heart. 

Peripheral artery disease (PAD) occurs when narrowed arteries reduce blood flow to the extremities, particularly the legs and feet. 

One of the most recognizable symptoms is leg pain or cramping that develops while walking and improves with rest. Other symptoms can include numbness, cold feet, slow-healing wounds, or changes in skin color. 

Identifying PAD is important because the condition can indicate more widespread atherosclerosis throughout the cardiovascular system. Memphis Vein Center includes PAD among the cardiovascular conditions it evaluates and treats. 

How Does a Cardiologist Check Your Heart? 

The right diagnostic test depends on your symptoms and cardiovascular risk factors. 

At Memphis Vein Center, cardiovascular testing may include several approaches. 

Echocardiogram 

An echocardiogram uses ultrasound technology to create moving images of your heart. 

It allows your cardiovascular team to examine the heart’s chambers, valves, structure, and pumping ability without surgery or radiation. 

Nuclear Stress Testing 

Some heart problems become easier to identify when the heart is working harder. 

A nuclear stress test can help evaluate blood flow to the heart during stress and identify areas that may not be receiving adequate blood supply. 

Vascular Ultrasound 

Ultrasound can also be used to evaluate circulation throughout the body. 

A vascular ultrasound may help identify narrowed or blocked blood vessels and evaluate how effectively blood is flowing through your arteries. 

Heart Catheterization 

When more detailed information is needed, your cardiologist may recommend heart catheterization. 

During this minimally invasive procedure, a thin catheter is guided through a blood vessel toward the heart. Imaging can then help identify narrowed or blocked coronary arteries. 

In certain cases, treatment such as angioplasty or stent placement can be performed during the same procedure. 

How Are Blocked Heart Arteries Treated? 

Treatment depends on the location and severity of the blockage, your symptoms, and your overall cardiovascular health. 

Lifestyle modifications and medications may be appropriate for some patients. When a blockage significantly restricts blood flow, an interventional procedure may be recommended. 

Balloon Angioplasty and Stent Placement 

During balloon angioplasty, a catheter carrying a small balloon is guided to the narrowed portion of an artery. 

The balloon is inflated to widen the artery and improve blood flow. A small mesh device called a stent may then be placed inside the artery to help keep it open. 

Coronary Atherectomy 

Some arterial plaque is particularly hard or calcified and may be difficult to treat with balloon angioplasty alone. 

Coronary atherectomy uses specialized catheter-based technology to remove or modify plaque within the artery. Angioplasty and stenting may then be performed when appropriate. 

These minimally invasive approaches allow certain cardiovascular problems to be treated through the blood vessels rather than traditional open surgery. 

When Should You See a Cardiologist? 

You don’t need to wait until you have severe symptoms to think about your heart health. 

A cardiovascular evaluation may be appropriate if you have persistent chest discomfort, unexplained shortness of breath, heart palpitations, dizziness, reduced exercise tolerance, leg circulation problems, or swelling in your lower extremities. 

You may also benefit from cardiovascular evaluation if you have important risk factors such as: 

• High blood pressure 

• High cholesterol 

• Diabetes 

• Smoking history 

• Family history of heart disease 

• Obesity 

• Previous cardiovascular disease 

Managing these risk factors early can play an important role in protecting your heart and circulation.
