When to See a Cardiologist
You may consider seeing a cardiologist if you have symptoms that could be related to the heart, particularly if they are new, persistent, recurrent or affecting your usual activities.
Some reasons for a cardiology assessment include:
- Chest pain, pressure or discomfort
- Shortness of breath during activity or at rest
- Heart palpitations or an unusually fast, slow or irregular heartbeat
- Dizziness or light-headedness
- Fainting or unexplained loss of consciousness
- Reduced exercise tolerance
- Persistent or unexplained fatigue
- Swelling of the feet, ankles or legs
- Abnormal blood pressure readings
- Abnormal ECG or other cardiac test results
These symptoms can have many possible causes and do not necessarily mean that you have heart disease. A medical assessment can help identify the underlying cause.
Chest pain is one of the more common reasons someone may be referred for a cardiac assessment.
Heart-related chest discomfort may be described as pressure, tightness, heaviness or squeezing. It can sometimes occur during physical activity and improve with rest. However, not all cardiac symptoms follow the same pattern, and chest discomfort can also arise from the lungs, digestive system, muscles or other structures in the chest.
A cardiologist may assess your symptoms together with your medical history and cardiovascular risk factors before determining whether cardiac testing is appropriate.
Sudden or severe chest pain, particularly when accompanied by shortness of breath, sweating, nausea, fainting, or pain spreading to the arm, jaw, back or shoulder, requires urgent medical attention.
Becoming unusually breathless during activities that were previously manageable may warrant medical assessment.
Shortness of breath can have cardiac and non-cardiac causes. From a cardiovascular perspective, it may occur with conditions affecting the heart muscle, heart valves, heart rhythm or the heart’s ability to pump blood effectively.
Assessment is particularly relevant when breathlessness is persistent or occurs together with chest discomfort, palpitations, swelling of the legs or reduced exercise capacity.
Palpitations can feel as though your heart is racing, pounding, fluttering, skipping beats or beating irregularly.
They can occur for many reasons, including exercise, stress, caffeine and certain medications. In some people, however, recurrent palpitations may be associated with an abnormal heart rhythm.
A cardiac assessment may be considered when palpitations occur frequently, last for prolonged periods or are accompanied by dizziness, chest discomfort, breathlessness or fainting.
Because an abnormal rhythm may not occur during a clinic appointment, tests such as a 12-lead ECG or ambulatory ECG monitoring may sometimes be used to record the heart’s electrical activity.
An occasional episode of light-headedness can have many causes. Recurrent dizziness, near-fainting or unexplained fainting may require further investigation.
In some cases, these symptoms can be associated with changes in heart rhythm, blood pressure or the heart’s ability to circulate blood effectively.
The circumstances surrounding the episode, such as whether it occurred during exercise, while standing, or together with palpitations or chest discomfort, can help determine which investigations may be appropriate.
High blood pressure and elevated cholesterol are cardiovascular risk factors that can often exist without noticeable symptoms.
Depending on your readings, medical history and other risk factors, assessment may involve reviewing whether lifestyle measures, medication or further cardiovascular investigations should be considered.
People who already have conditions such as diabetes, kidney disease or established cardiovascular disease may also require closer management of their cardiovascular risk factors.
Family history can be relevant when assessing cardiovascular risk, particularly when a close relative developed cardiovascular disease at a relatively young age.
A cardiology consultation does not automatically mean extensive testing is required. Your doctor may first review factors such as:
- Your age and medical history
- Blood pressure
- Cholesterol levels
- Diabetes
- Smoking history
- Exercise and lifestyle
- Symptoms
- The type and age of onset of cardiovascular disease in your family
This information can help determine whether additional assessment or testing is appropriate.
Not everyone who sees a cardiologist has symptoms.
A cardiovascular assessment may be considered when there are known risk factors, an abnormal finding during another medical examination, or concerns arising from tests such as an ECG.
Whether heart screening is appropriate, and which tests are suitable, depends on factors such as age, symptoms, medical history and individual cardiovascular risk.
Not every patient requires the same tests. Investigations are selected according to the reason for consultation, symptoms, examination findings and medical history.
At Apex Heart Clinic, cardiac investigations available include:
12-Lead Electrocardiogram (ECG)
Records the heart’s electrical activity and can provide information about heart rhythm and other cardiac abnormalities.
Echocardiography
Uses ultrasound to assess the structure and function of the heart, including the heart chambers, valves and pumping function.
Treadmill Stress Test
Assesses the heart’s response to physical exercise while the heart rhythm and other clinical parameters are monitored.
24-Hour ECG Monitoring
Records heart rhythm over a longer period and may be considered for intermittent symptoms such as palpitations, dizziness or fainting.
24-Hour Blood Pressure Monitoring
Records blood pressure at intervals throughout the day and night to provide information beyond individual clinic readings.
Cardiac CT
May be used in selected patients to provide further information about the coronary arteries or other cardiac structures.
The appropriate investigation, if any, is determined following clinical assessment.
A cardiology consultation generally begins with a review of your symptoms and medical history.
You may be asked about when your symptoms started, what brings them on, how long they last and whether anything makes them better or worse. Your cardiologist may also review your medications, previous medical conditions and family history.
A physical examination may then be performed. Depending on the findings, further cardiac tests may be recommended to help establish a diagnosis or guide management.
If you have previous ECGs, scans, blood test results, medication lists or other relevant medical reports, bringing them to the appointment can provide useful clinical information.
Some symptoms should not wait for a routine cardiology appointment.
Seek urgent medical attention if you experience symptoms such as:
- Sudden or severe chest pain or pressure
- Chest discomfort accompanied by sweating, nausea or breathlessness
- Severe difficulty breathing
- Sudden loss of consciousness
- Persistent chest discomfort spreading to the arm, shoulder, jaw or back
- Sudden weakness, facial drooping or difficulty speaking
- A rapid or irregular heartbeat accompanied by severe dizziness, chest pain or fainting
If symptoms are severe or you think you may be experiencing a medical emergency, seek emergency medical care promptly.
