If you’re experiencing chest pain and shortness of breath, it might be a sign to get checked for something serious. Whether it’s symptoms you’ve noticed or peace of mind you need, don’t wait to seek heart care.

Why you might need a heart doctor

Your heart works incredibly hard every single day, and sometimes it needs specialized attention from a qualified heart doctor. Understanding when to seek cardiac care can be the difference between prevention and emergency treatment.

A heart doctor, also called a cardiologist, specializes in diagnosing and treating conditions affecting your heart and blood vessels. These heart specialists are trained to identify early warning signs that there could be issues with your heart.

6 warning signs that you may need to see a heart doctor

1. Chest pain or discomfort

Chest pain is the most common reason people seek care from a heart doctor, and for good reason. Any chest discomfort should be taken seriously and evaluated by a cardiac specialist.

“I tell patients I would rather see them to make sure there is nothing more serious happening,” said Jason A. Hopper, M.D., cardiologist with Norton Heart & Vascular Institute. “Truly, better safe than sorry.”

That tightness, pressure or pain you’re experiencing? Don’t ignore it. It could be a warning sign of:

  • Heart attack or angina
  • Coronary artery disease
  • Heart valve issues
  • Inflammation of the heart muscle (pericarditis)

A heart doctor can distinguish between cardiac chest pain and other causes, such as muscle strain or acid reflux. Even if your chest pain isn’t heart-related, seeing a heart doctor can provide peace of mind and rule out serious conditions.

2. Shortness of breath, even at rest

Experiencing unexplained shortness of breath is a significant red flag that requires immediate evaluation by a heart doctor. This symptom can indicate that your heart is struggling to pump blood effectively throughout your body.

Especially concerning is shortness of breath that’s new or getting worse. A heart doctor should evaluate you if you experience:

  • Difficulty breathing during normal activities
  • Breathlessness while lying flat
  • Waking up short of breath at night
  • Breathing issues that interfere with daily life

These symptoms could indicate heart failure, coronary artery disease or other serious cardiac conditions that require prompt treatment from a heart doctor.

3. High blood pressure

Uncontrolled high blood pressure can cause significant damage to your heart over time. A heart doctor can help you understand your blood pressure readings and develop an effective management strategy.

Consider seeing a heart doctor if:

  • Your blood pressure consistently reads above 140/90 (measured in millimeters of mercury, abbreviated as mmHg)
  • You’re taking medication but still have elevated readings
  • You have other cardiovascular risk factors
  • You’ve been diagnosed with high blood pressure but haven’t seen a specialist

“High blood pressure often has no symptoms,” Dr. Hopper said. “Keeping a baseline of your blood pressure is crucial for preventing heart attack, stroke and heart failure.”

4. Family history of heart disease

If heart issues run in your family, it’s smart to get ahead of conditions by consulting with a heart doctor. Heart disease is influenced by genetics, so knowing your family history and taking proactive action can save your life.

A heart doctor should evaluate you if you have:

  • Parents or siblings with heart disease
  • Family history of heart attacks before age 65
  • Genetic conditions affecting the heart
  • Multiple relatives with cardiovascular issues

Even if you’re currently healthy, a heart doctor can assess your risk and recommend preventive measures based on your family history.

5. Irregular heartbeat or palpitations (rapid or abnormal heartbeat)

Your heart should maintain a steady, regular rhythm. If your heart feels like it’s skipping, fluttering or racing, it’s time to check it out with a heart doctor.

Seek evaluation from a heart doctor if you experience:

  • Heart palpitations that occur frequently
  • Feeling like your heart is skipping beats
  • Rapid or slow heart rate without explanation
  • Irregular heartbeat patterns

While occasional palpitations can be normal, irregular heartbeats that don’t go away could indicate arrhythmias that require treatment from a heart doctor.

6. You have diabetes

Diabetes significantly increases your risk of heart disease, making regular check-ins with a specialist essential for managing your overall health. A heart doctor can help prevent cardiovascular complications associated with diabetes.

If you have diabetes, a heart doctor can:

  • Monitor your cardiovascular risk factors
  • Adjust medications to protect your heart
  • Provide specialized care for diabetic heart disease
  • Help manage your condition to prevent heart issues

Diabetes increases your risk of heart disease because high blood sugar damages blood vessels over time. Regular consultations with a heart doctor can help manage your condition and prevent serious complications.

Don’t wait for a crisis: Early action saves lives

You don’t need to wait for a medical emergency to see a cardiac specialist. If something feels off with your heart or you simply want peace of mind about your cardiovascular health, seeing a heart doctor can be a smart move.

Listen to your body and trust your gut. Early detection and treatment by a qualified heart doctor can prevent minor issues from becoming life-threatening emergencies. 

What to expect during your first heart doctor visit

When you visit a heart doctor for the first time, they will:

  • Review your medical history and family history
  • Perform a comprehensive physical examination
  • Order diagnostic tests such as an electrocardiogram (abbreviated as EKG) echocardiogram, stress testing or cardiac CT scan.
  • Discuss your symptoms and risk factors
  • Develop a personalized treatment plan

Benefits of regular cardiac care

Working with a heart doctor provides numerous advantages for your cardiovascular health:

Early detection: Heart doctors can identify problems before they become serious, allowing for early intervention and better outcomes.

Specialized expertise: Heart doctors have advanced training in cardiac conditions.

Advanced testing: Heart doctors have access to sophisticated diagnostic equipment and testing procedures.

Comprehensive care: A heart doctor can coordinate with other specialists to provide complete cardiovascular care.

Peace of mind: Regular checkups with a heart doctor can provide reassurance about your heart health.

Don’t delay seeking care if you’re experiencing any warning signs. However, even if you’re symptom-free, consider seeking cardiology care if you:

  • Are over 40 with multiple risk factors
  • Have concerns about your cardiovascular health
  • Want to establish baseline heart health
  • Need guidance on heart-healthy diet and lifestyle changes

Heart disease remains one of the leading causes of death, but it’s also largely preventable with proper care from qualified medical professionals. A heart doctor can help you understand your risk factors and take steps to protect your heart.
