When to See a Cardiologist in Sheepshead Bay: Warning Signs and Next Steps

By the IDCC Health editorial team

Why See a Cardiologist in Sheepshead Bay?

Heart problems often begin with small warning signs. Chest pain or pressure, shortness of breath, a racing or skipping heartbeat, dizziness, and swelling in the legs or ankles can all point to an issue with your heart. If you ever have sudden, severe chest pain or trouble breathing, call 911 before anything else. For symptoms that are new, persistent, or worrying, a cardiologist can help find the cause and start a treatment plan. The Cardiology team at IDCC Health focuses on prevention, diagnosis, and long-term management of heart conditions.

Many people first learn about their heart risk during a routine checkup. High blood pressure, diabetes, high cholesterol, smoking, older age, and a family history of heart disease all raise your chances of developing a problem. Your Primary Care doctor can track these numbers and decide when a referral makes sense. For example, if your blood pressure stays high despite lifestyle changes, a cardiologist can dig deeper. For more on this common issue, read our article Should I See a Cardiologist for High Blood Pressure? Catching problems early is one of the best ways to protect your heart.

Your first visit with a cardiologist usually includes a detailed medical history, a physical exam, and an electrocardiogram (ECG) to check your heart's rhythm. The doctor may also order blood tests or a heart monitor. At IDCC Health, cardiologist Alexander Natanzon MD works with patients to explain each step and answer questions. The goal is to keep you moving and living well.

Warning Signs That Should Prompt a Cardiology Visit

The warning signs described above deserve attention, and some should never be ignored. If you have sudden chest pain, trouble breathing, or fainting, call 911 first; emergency care is the right move for a possible heart attack. For symptoms that are new, persistent, or worrying, a Cardiology visit can help you understand what is going on.

Your risk factors matter too. Many people first learn about these risks during a routine checkup with a Primary Care doctor, who can run basic tests and decide whether a referral to a cardiologist makes sense. At our practice, Alexander Natanzon MD is the cardiologist who sees patients for these concerns.

Once you are referred, the cardiologist will review your medical history, listen to your heart, and may run an ECG to check your heart's rhythm. If your symptoms include dizziness, the cause may also involve the nervous system, so our Neurology team can work with your cardiologist. The goal is to find the cause and create a plan that fits your life.

Chest pain or pressure that comes and goes
Shortness of breath during mild activity or at rest
Heart palpitations, such as a racing or skipping heartbeat
Dizziness or lightheadedness that is new or frequent
Unexplained swelling in the legs, feet, or ankles

Heart Disease Risk Factors: Do You Need a Screening?

Heart disease does not always announce itself with clear symptoms, so a screening looks for signs of trouble before symptoms appear. Most people first discuss their risk factors with a Primary Care doctor, who can check blood pressure, cholesterol, and blood sugar. If those numbers are off, or if your family history raises concern, a referral to Cardiology may be the next step. According to MedlinePlus, common heart disease risk factors include high blood pressure, high LDL cholesterol, diabetes, smoking, being overweight, and lack of physical activity. Family history also matters: if a parent or sibling had heart disease at a younger age, your own risk may be higher.

A screening is not the same as an emergency visit. Sudden chest pain, pressure, fainting, or severe shortness of breath need emergency care right away. For gradual concerns, an appointment lets a cardiologist such as Alexander Natanzon MD evaluate your risk and plan next steps. During the visit, the care team reviews your medical history, checks your blood pressure, listens to your heart, and may order an ECG as well as blood tests or a stress test. The goal is to catch problems early, when they are easier to manage.

High blood pressure, or readings that stay above the normal range.
High cholesterol, especially high LDL ("bad") cholesterol.
Diabetes or prediabetes.
Smoking or tobacco use.
A family history of early heart disease.
Being overweight or physically inactive.
Older age, since risk rises as we get older.

What Happens at a First Cardiology Appointment?

Your first cardiology appointment usually starts with a detailed conversation. The doctor will ask about your symptoms, medical history, and any heart-related conditions in your family. Bring a list of your current medications, your insurance card, and any records from your primary care doctor. You will also have your blood pressure, heart rate, and weight checked. Most visits include an ECG, a quick test that records the electrical activity of your heart. For most appointments, you can eat and drink normally, but you can review our guide on Can You Eat Before a Cardiology Appointment? for specific instructions.

After the exam, the cardiologist will explain what they found and what comes next. They may order blood tests, a stress test, or a heart ultrasound. If you were referred by a primary care doctor, those records help the cardiologist get a full picture. At IDCC Health, Alexander Natanzon MD leads the Cardiology team and sees patients at the 445 Kings Highway office, which is easy to reach from many parts of Brooklyn. The goal of the first visit is to create a clear plan, whether that means starting treatment, adjusting medications, or scheduling follow-up care.

Referrals: Primary Care, Ambulatory Referrals, and Self-Referral

Most people see a cardiologist after a referral from their Primary Care doctor, who handles routine checkups and blood tests. When those checkups reveal high blood pressure, high cholesterol, or other risk factors that need a specialist, they send a referral. At IDCC Health, family medicine doctor Stella Geller DO works closely with the cardiology team.

Some patients receive an ambulatory referral, meaning the referral comes from a doctor's office rather than a hospital stay; it is the most common type for heart concerns. For a detailed look, see our article What is Ambulatory Referral to Cardiology? You can also self-refer: call the cardiology office directly and book an appointment without a referral. Many insurance plans allow this, but it is smart to check with your plan first.

At your first visit, the cardiologist, Alexander Natanzon MD, will review your medical history and may order an ECG. Bring your insurance card, a list of medications, and any recent test results. The team can also help you understand your insurance coverage and answer questions about self-pay options.

Cost, Insurance, and Local Cardiology Offices in Brooklyn

Most insurance plans cover cardiology visits, but your exact out-of-pocket cost depends on your plan's copay, deductible, and whether the cardiologist is in network. If you do not have insurance, the cost of a first visit can vary widely; for a breakdown of typical prices and payment options, see How Much Does It Cost to See a Cardiologist Without Insurance? Some plans also require a referral from a Primary Care doctor before they will cover a specialist visit, often called an ambulatory referral; read What is Ambulatory Referral to Cardiology? to understand that process. The National Institutes of Health notes that managing risk factors like high blood pressure and high cholesterol is key to preventing heart disease, so a regular checkup with a Primary Care doctor is a good starting point.

If you are unsure whether your symptoms need a specialist, you can start with a primary care visit to get guidance.

Frequently Asked Questions About Seeing a Cardiologist

Many patients wonder whether they need a referral before seeing a cardiologist. The answer depends on your insurance, not on your symptoms. Some plans let you book directly with a specialist like Alexander Natanzon MD, while others ask you to start with Primary Care so your doctor can decide whether a referral to Cardiology is right for you. For more about what happens at a first appointment, including whether you should eat beforehand, see our guide on Can You Eat Before a Cardiology Appointment?

Warning signs like chest pressure, shortness of breath, palpitations, dizziness, or swelling in your legs should not be ignored.
