Common Heart Conditions We Diagnose and Manage
At IDCC, our cardiology team diagnoses and manages a wide range of heart conditions. These include high blood pressure (hypertension), arrhythmias (irregular heartbeats), heart failure, coronary artery disease, and valve problems. We also evaluate palpitations and conditions like POTS, which can cause dizziness and a rapid heartbeat when standing. According to the National Institutes of Health, many heart conditions develop slowly and can be managed better when they are found early.
When to See a Cardiologist: The Role of Primary Care
Your Primary Care doctor is often the first person you talk to about heart health. They can check your blood pressure, cholesterol, and other risk factors during routine visits. They can also spot early signs of heart trouble and guide you on next steps. For many people, Primary Care is enough to keep their heart healthy. But sometimes, a specialist is needed.
You should see a cardiologist if you have symptoms such as chest pain, shortness of breath, palpitations, or dizziness. A family history of heart disease or abnormal test results from your Primary Care doctor are also reasons to get a specialist's opinion. Alexander Natanzon MD, a cardiologist at our practice, works closely with Primary Care doctors to provide expert heart care. He can run more detailed tests and create a treatment plan tailored to you. According to the American Academy of Family Physicians, early detection and management of heart disease risk factors can significantly improve outcomes. Common risk factors include high blood pressure, high cholesterol, smoking, diabetes, and a sedentary lifestyle. If you have any of these, talk to your Primary Care provider about whether a cardiology evaluation is right for you.
In some cases, your Primary Care doctor will set up an ambulatory referral to cardiology. This is a scheduled, non-emergency appointment with a heart specialist. You can learn more about how this process works in our article What is Ambulatory Referral to Cardiology?. Before your visit, you may be told to fast or avoid certain foods. Our guide Can You Eat Before a Cardiology Appointment? explains the typical instructions. Appointments are available at our locations, including 445 Kings Highway and 2846 Stillwell Avenue.
- Chest pain or pressure
- Shortness of breath, especially with activity
- Irregular heartbeat or palpitations
- High blood pressure that does not respond to treatment
- A history of heart attack, stroke, or heart failure
- A family history of early heart disease
What to Expect During Your Cardiology Visit
Your first visit with Alexander Natanzon MD starts with a thorough review of your medical history, family history, and current symptoms. He will listen to your heart, check your blood pressure, and ask about your lifestyle, including diet, exercise, and stress levels. Because heart health is closely tied to overall wellness, Dr. Natanzon often coordinates with your Primary Care provider to ensure your care plan is fully integrated.
Depending on your symptoms, Dr. Natanzon may recommend diagnostic tests such as an electrocardiogram (EKG), an echocardiogram, or a stress test. For some conditions, you might need a wearable monitor for a day or two, which is part of an ambulatory referral. If you're curious about how that process works, our article What is Ambulatory Referral to Cardiology? explains it in detail. Also, some blood tests require fasting beforehand, so check our guide Can You Eat Before a Cardiology Appointment? to know exactly how to prepare. According to MedlinePlus, these tests help identify heart diseases early, which improves treatment outcomes.
After your evaluation, Dr. Natanzon will discuss your results and create a personalized treatment plan. This may include medications, lifestyle changes, or further testing. For busy New Yorkers, small daily habits can make a big difference, and our article Heart-Healthy Habits for Busy New Yorkers offers practical tips. If you need ongoing care, you can visit us at our 445 Kings Highway location or our other offices. The entire team is here to support you, from Rehabilitation and Pain Management to Physical Therapy and Neurology, so you have access to comprehensive care under one roof. It's also helpful to bring a list of any supplements you take, as some can affect heart health. If you have a family history of heart disease, let Dr. Natanzon know so he can assess your risk.
- Bring a list of your current medications and any past test results.
- Wear comfortable clothing and avoid heavy meals or caffeine before your appointment unless instructed otherwise.
- Arrive 15 minutes early to complete any necessary paperwork.
Heart-Healthy Living for Busy New Yorkers
Living in a busy city means a packed schedule, but heart health doesn't have to take a back seat. Small, consistent choices can make a big difference. For practical strategies tailored to your daily routine, our guide on Heart-Healthy Habits for Busy New Yorkers offers simple swaps for meals, movement, and stress relief. The National Institutes of Health also provides evidence-based tips on preventing heart disease.
Beyond diet and exercise, managing stress and getting enough sleep are key. If you experience dizziness or rapid heartbeat when standing, you might be dealing with POTS syndrome. Our article Can POTS Syndrome Kill You? What You Need to Know explains the symptoms and when to seek help. For ongoing support, your Primary Care provider can monitor your blood pressure and cholesterol, and coordinate with a cardiologist like Alexander Natanzon MD when needed. Chronic stress can take a toll on your heart. Finding healthy ways to cope, such as meditation, yoga, or talking to a therapist, is important. Our Psychiatry and Occupational Therapy services can support your mental and physical well-being.
These habits are best discussed with your care team. At our office at 445 Kings Highway, we offer cardiology consultations and follow-ups. For more information on heart conditions, MedlinePlus is a trusted resource. Remember, even small steps like a daily walk or choosing water over sugary drinks can protect your heart for years to come.
- Choose whole grains instead of refined carbs.
- Add a 10-minute walk after meals.
- Practice deep breathing for 5 minutes daily.
- Aim for 7-9 hours of sleep.
Preventive Cardiology: Key Steps
Prevention is the cornerstone of heart health. Even if you have no symptoms, regular checkups can catch risk factors like high cholesterol, high blood pressure, and diabetes early. According to the American Heart Association, managing these conditions can significantly reduce your risk of heart disease. Our team works with you to create a prevention plan that fits your lifestyle.
Simple changes like quitting smoking, maintaining a healthy weight, and staying active are proven to lower your risk. The National Institutes of Health recommends at least 150 minutes of moderate exercise per week. If you need guidance, our Physical Therapy and Rehabilitation departments can help you build a safe exercise routine. For more tips, see our guide on Heart-Healthy Habits for Busy New Yorkers.
