Advanced heart care for breathing concerns

What Does Shortness of Breath Feel Like?

Shortness of breath affects people differently. You may experience:

• Difficulty taking a satisfying or complete breath
• A sensation that you cannot get enough air
• Unusual breathlessness during ordinary activity
• A need to stop and rest while walking
• Rapid or shallow breathing
• Tightness or heaviness in the chest
• Difficulty breathing while lying flat
• Waking suddenly during the night feeling breathless
• Breathlessness accompanied by fatigue, swelling or palpitations

The pattern matters. Symptoms that occur only with strenuous exercise may have a different explanation than symptoms appearing during routine activity, while resting or while lying down.

Breathing difficulty when lying flat is called orthopnea. Waking suddenly at night feeling short of breath is often described as paroxysmal nocturnal dyspnea. Both patterns may occur with heart failure, although they can have other causes and require clinical evaluation.

When Should You See a Cardiologist for Shortness of Breath?

A cardiology evaluation may be appropriate when breathlessness is new, unexplained, recurring or progressively limiting your activities.

Consider requesting an appointment when you notice:

• Shortness of breath during walking or routine household tasks
• Becoming winded while climbing one flight of stairs
• A noticeable decline in exercise tolerance
• Breathing difficulty while lying flat
• Waking from sleep because you cannot breathe comfortably
• Breathlessness accompanied by ankle or leg swelling
• Unexplained rapid weight changes
• Shortness of breath with chest discomfort
• A rapid, pounding, skipped or irregular heartbeat
• Dizziness, weakness or near-fainting during activity
• Persistent fatigue with reduced stamina
• Symptoms following a recent heart-related hospitalization
• New symptoms when you already have coronary disease, heart failure or valve disease

You may also benefit from evaluation when you have cardiovascular risk factors such as high blood pressure, diabetes, high cholesterol, tobacco use, kidney disease or a strong family history of heart disease.

Stable symptoms can generally be evaluated through a scheduled visit. Sudden, severe or rapidly worsening symptoms require emergency care rather than an outpatient appointment.

Trusted answers for shortness of breath

Can Heart Problems Cause Shortness of Breath?

Yes. The heart and lungs work together to circulate oxygen throughout the body. A problem affecting heart pumping, filling, blood flow, rhythm or valves can make normal activity feel more difficult.

However, shortness of breath is not specific to heart disease. It should not be assumed to be cardiac until a qualified clinician evaluates the symptoms, examination findings and test results.

Heart failure

Heart failure may cause blood and fluid to back up toward the lungs, leading to breathlessness during activity, at rest, while lying flat or during the night. Patients may also experience swelling, rapid weight changes, fatigue, cough or reduced exercise tolerance.

Coronary artery disease

Narrowed coronary arteries may reduce blood flow to the heart muscle. Some patients experience chest pressure, but others may notice shortness of breath, fatigue, nausea or reduced exercise tolerance. Breathlessness can sometimes function as an anginal equivalent, particularly when it occurs predictably during physical effort.

Heart-rhythm disorders

A heart rate that is too fast, too slow or irregular can affect how efficiently the heart fills and pumps. Some patients experience shortness of breath together with palpitations, weakness, chest discomfort, dizziness or fainting.

Heart-valve disease

A narrowed or leaking heart valve may interfere with normal forward blood flow. Symptoms can include exertional breathlessness, fatigue, swelling, chest discomfort, dizziness or fainting. An echocardiogram is commonly used to assess heart-valve structure and blood flow.

Cardiomyopathy

Cardiomyopathy affects the heart muscle. Depending on the type, it can weaken the heart, make the muscle abnormally thick or interfere with normal filling. Symptoms may include breathlessness, fatigue, swelling, palpitations or fainting.

High blood pressure

Long-standing or poorly controlled high blood pressure can place additional strain on the heart. Over time, it may contribute to heart-muscle thickening, impaired filling, coronary disease or heart failure.

Pulmonary hypertension

Pulmonary hypertension is elevated pressure in blood vessels that carry blood through the lungs. It can make the right side of the heart work harder and may cause shortness of breath, fatigue, chest discomfort, swelling, lightheadedness or fainting.

Shortness of Breath Is Not Always Caused by the Heart

Many noncardiac conditions can cause or contribute to breathing difficulty, including:

• Asthma
• Chronic obstructive pulmonary disease
• Pneumonia or another respiratory infection
• Pulmonary embolism
• Anemia
• Thyroid disease
• Kidney disease
• Obesity or physical deconditioning
• Sleep-disordered breathing
• Medication effects
• Anxiety or panic symptoms
• Neuromuscular conditions
• Environmental or occupational exposures

Some patients have more than one cause. For example, a person may have both heart disease and a chronic lung condition. Anemia, kidney disease or deconditioning may also make an existing cardiovascular condition feel worse.

Anxiety can produce rapid breathing, chest tightness and the sensation of not getting enough air, but patients should not automatically attribute new or severe symptoms to anxiety without appropriate medical evaluation. Heart and lung diseases can produce similar sensations.

If the evaluation points primarily toward a pulmonary or another noncardiac condition, Advanced Cardiology may recommend follow-up with the appropriate clinician rather than continuing unnecessary cardiac testing.

Shortness of Breath While Walking or Climbing Stairs

Becoming mildly winded during strenuous exercise can be normal. Becoming short of breath during routine, age-appropriate activity—particularly when the change is new or worsening—may deserve evaluation.

Examples include:

• Needing to stop after walking a short distance
• Becoming winded while shopping
• Difficulty keeping pace with other people
• Shortness of breath climbing a single flight of stairs
• Needing frequent rest during household tasks
• A decline from your previous exercise ability
• Breathlessness accompanied by chest pressure, palpitations or dizziness

The clinician will consider your previous activity level, age, medical history, current medications and how quickly the change developed. Symptoms associated with ordinary activity can occur with heart failure and several lung conditions.

Shortness of Breath While Lying Down or Sleeping

Difficulty breathing while flat may cause a person to sleep with several pillows or in a recliner. Other patients fall asleep comfortably but awaken suddenly feeling unable to catch their breath.

These symptoms can occur when changes in body position increase blood return to the heart and contribute to congestion in a person with heart failure. They can also be associated with lung disease, sleep apnea, obesity and other conditions.

Tell your cardiologist:

• How many pillows you need
• Whether the symptom is new
• Whether you awaken coughing or gasping
• Whether sitting or standing improves the symptom
• Whether you also have swelling or rapid weight changes
• Whether you have been diagnosed with sleep apnea

New or worsening nighttime breathlessness should not be ignored. Severe symptoms require urgent or emergency evaluation.

Shortness of Breath With Chest Pain

Breathlessness accompanied by chest pressure, squeezing, fullness or pain may indicate a cardiovascular emergency, especially when symptoms are sudden, severe or accompanied by sweating, nausea, weakness or lightheadedness.

Heart-attack symptoms vary, and shortness of breath can occur with or without obvious chest discomfort. Call 911 when symptoms may represent a heart attack.

Stable, recurring symptoms that have already been medically assessed may still require cardiology follow-up to determine whether coronary artery disease, valve disease, heart failure or another cardiovascular problem is contributing.

Shortness of Breath With Palpitations

A fast, pounding, fluttering, skipped or irregular heartbeat can occur together with breathlessness. Potential explanations include:

• Atrial fibrillation
• Supraventricular tachycardia
• Frequent premature beats
• A heart rate that is too slow
• Medication effects
• Thyroid abnormalities
• Anemia
• Dehydration
• Anxiety
• Another rhythm disturbance

An office EKG records the rhythm at a single point in time. When symptoms come and go, a Holter monitor, event monitor or mobile cardiac telemetry device may be considered to record the rhythm over a longer period.

How Shortness of Breath Is Evaluated

A useful evaluation begins with the details of the symptoms rather than automatically ordering every available heart test.

Medical history

Dr. Khalid may ask:

• When the breathlessness began
• Whether it started suddenly or gradually
• What activities trigger it
• Whether it occurs while resting
• Whether lying down makes it worse
• Whether you awaken at night feeling breathless
• Whether you have chest discomfort, palpitations or dizziness
• Whether your legs or abdomen are swollen
• Whether your weight has recently changed
• Whether you have cough, wheezing, fever or mucus
• Whether you have had recent surgery, hospitalization or prolonged travel
• Whether you have a history of blood clots
• Whether you smoke or previously smoked
• Whether you have heart, lung, kidney or thyroid disease
• Which prescriptions, over-the-counter products and supplements you use

The timing and pattern may help narrow the possible causes.

Physical examination

The evaluation may include:

• Blood pressure and pulse
• Heart rate and rhythm
• Oxygen saturation
• Breathing rate
• Examination of the heart and lungs
• Assessment for swelling or fluid retention
• Evaluation for a heart murmur
• Review of circulation and other relevant findings

A normal office examination does not automatically exclude every cardiac or pulmonary condition. Further evaluation depends on the overall clinical picture.

Cardiac Tests That May Be Considered

Not every patient needs every test. Testing should be chosen according to the symptoms, physical findings, medical history and results already available.

Electrocardiogram

An EKG or ECG records the heart’s electrical activity. It may reveal:

• A fast, slow or irregular rhythm
• Atrial fibrillation
• Electrical-conduction abnormalities
• Evidence suggesting a previous heart attack
• Heart-muscle strain or enlargement patterns

An EKG can be normal even when a person has intermittent rhythm symptoms or certain forms of coronary disease.

Echocardiogram

An echocardiogram uses ultrasound to evaluate the heart’s structure and function. It may assess:

• Heart pumping function
• Ejection fraction
• Heart-muscle thickness
• Chamber size
• Filling patterns
• Heart-valve narrowing or leakage
• Estimated pressure in the pulmonary circulation
• Fluid surrounding the heart

Echocardiography is commonly used when symptoms may be related to heart failure, valve disease, cardiomyopathy or pulmonary hypertension.

Blood tests

Depending on the clinical situation, testing may include:

• Complete blood count to evaluate for anemia or infection
• Kidney and liver function
• Electrolytes
• Thyroid testing
• Blood glucose
• BNP or NT-proBNP when heart failure is being considered
• Other testing selected according to the symptoms

BNP and NT-proBNP can provide information about cardiac stress and may help support or make heart failure less likely, but these tests must be interpreted with the patient’s age, kidney function, body size, rhythm and other clinical findings. They do not replace the history, examination and imaging.

Stress testing

Exercise or medication-based stress testing may be considered when symptoms appear with exertion and coronary disease is a concern. The appropriate type depends on the patient’s ability to exercise, baseline EKG, medical history and previous test results.

A normal stress test does not explain every form of breathlessness, and testing should be selected rather than ordered routinely.

Heart-rhythm monitoring

A Holter monitor, event monitor or mobile cardiac telemetry device may be considered when breathlessness occurs with intermittent palpitations, racing heartbeat, dizziness or fainting.

Chest imaging or pulmonary testing

A chest X-ray, chest CT scan, pulmonary-function testing or another lung evaluation may be ordered or coordinated when symptoms suggest pneumonia, COPD, interstitial lung disease, a pleural condition, pulmonary embolism or another noncardiac explanation. Chest CT can help evaluate certain causes of breathlessness, including lung disease, fluid around the lungs and pneumonia.

Coronary or advanced cardiac testing

Selected patients may need coronary CT angiography, nuclear imaging, cardiac MRI or cardiac catheterization. These tests should be recommended only when the patient’s symptoms, risk level and preliminary findings support the need.

Do not state that these tests are performed at both offices unless that is operationally correct.

What Happens After the Evaluation?

Treatment is based on the identified or suspected cause—not simply on the symptom of shortness of breath.

When heart failure is contributing

The plan may involve:

• Evidence-based heart-failure medication
• Treatment of fluid congestion
• Blood-pressure management
• Kidney and electrolyte monitoring
• Daily symptom or weight tracking
• Evaluation for a device or advanced treatment in selected patients
• Follow-up to adjust treatment over time

When coronary disease is suspected

The plan may include:

• Cardiovascular risk-factor management
• Medication when appropriate
• Further coronary testing
• Evaluation for angiography or revascularization in selected patients
• Emergency referral when symptoms may represent an acute coronary syndrome

When a rhythm problem is identified

Treatment depends on the rhythm and may involve:

• Medication review
• Heart-rate or rhythm management
• Additional monitoring
• Anticoagulation assessment for selected rhythms
• Referral for an electrophysiology procedure when appropriate

When a valve problem is contributing

Care may include periodic echocardiography, symptom monitoring, medication for associated conditions or referral for surgical or catheter-based treatment when the valve disease becomes significant.

When high blood pressure is contributing

Treatment may focus on obtaining accurate readings, reviewing current medication, addressing cardiovascular risk and evaluating whether hypertension has affected heart structure or function.

When the cause is not primarily cardiac

Dr. Khalid may recommend follow-up with:

• A primary-care clinician
• A pulmonologist
• A sleep-medicine specialist
• A hematologist
• Another appropriate specialist

Good care sometimes means confirming that the heart is not the main source and directing the patient to the clinician best positioned to continue the evaluation.
