Early Warning Signs of Heart Failure You Shouldn’t Ignore
Heart failure announces itself quietly, in pillows, bathroom scales, and abandoned stairs. The early warning signs
Cardiac risk assessment before surgery — timely evaluation, clear documentation, and direct communication with your surgical team.
Preoperative cardiac clearance is an assessment of whether your heart can safely tolerate a planned operation, and of what should be done beforehand to reduce the risk of a complication.
It is not a formality or a signature. It is a genuine risk assessment that weighs your cardiac history against the demands of the specific operation you are having.
Surgeons and anesthesiologists request clearance when a patient has known heart disease, cardiac risk factors, or symptoms that have not been evaluated. We offer timely appointments and clear written documentation so that surgery is not delayed.
When your surgery depends on a cardiac opinion, it matters that the assessment is done properly and quickly. Our cardiologists assess each patient individually and document the reasoning clearly for the team who will be looking after you in theatre.

Not every patient needs cardiac clearance before an operation. It is usually requested when you have:
Your functional capacity — how much physical activity you can manage without symptoms — is one of the strongest predictors of surgical risk, and often more informative than any test.
Preoperative risk is shaped by several underlying cardiac conditions. Learn more about:
If you develop chest pain, severe breathlessness, or fainting while waiting for surgery, call 911 immediately and tell your surgical team afterwards.
Do not wait for an office appointment.
Online appointment requests should never be used for potentially life-threatening symptoms.
Clearance weighs two things against each other: your individual cardiac risk, and how demanding the planned operation is.
Being able to climb a flight of stairs without stopping is a genuinely useful benchmark, and patients who can do it comfortably often need no further cardiac testing at all.
The assessment is deliberately proportionate. Testing is arranged only where the result would genuinely change what happens before or during your operation.
Your risk of a perioperative cardiac event, calculated from your history and the type of surgery planned rather than estimated informally.
How much physical activity you can manage without symptoms, which is one of the strongest available predictors of how you will tolerate surgery.
Investigations arranged only when the result would alter management. Most clearances need no testing beyond an ECG.
Clear guidance on which cardiac medications continue, which pause, and exactly when — particularly antiplatelets and anticoagulants.
Where a condition is not well controlled, treating it beforehand often reduces risk more than any test result would.
A clear report sent to your surgeon and anesthesiologist stating the assessment, the risk, and any specific recommendations.
Medication decisions around an operation are genuinely consequential, and are made jointly between your cardiologist, surgeon, and anesthesiologist. Commonly reviewed are:
Do not stop any cardiac medication on your own before surgery. Stopping antiplatelet therapy too early after a stent carries real risk. Bring your full medication list and we will provide written instructions for your surgical team.
A small number of cardiac conditions account for most of the risk associated with non-cardiac surgery. Where these are present, assessment matters more.
Narrowed coronary arteries raise the risk of a perioperative cardiac event, particularly where symptoms are unstable. Read more about coronary artery disease.
Reduced pumping function is one of the strongest predictors of perioperative complications, and is worth optimizing beforehand. Read more about heart failure.
Rate control and anticoagulation both need planning around an operation, and the timing is specific. Read more about atrial fibrillation.
Significant narrowing of the aortic valve in particular changes anesthetic management and may need addressing first.
Poorly controlled pressure can delay surgery, and is usually straightforward to improve in the weeks beforehand. Read more about high blood pressure.
Not every patient needs every cardiac test. Testing should be selected based on your symptoms, examination, medical history, and cardiovascular risk. Depending on your individual situation, your cardiologist may recommend one or more of the following.
Measures the heart's electrical activity and may identify rhythm problems or other cardiac changes.
Uses ultrasound to evaluate heart function, chambers, valves, muscle, and structure.
Shows how the heart responds to physical activity and may help evaluate exercise-related symptoms.
Uses cardiac imaging during stress testing to assess blood flow to the heart muscle.
Records heart rhythm over time to help detect intermittent arrhythmias or palpitations.
Blood tests may evaluate cholesterol, blood sugar, kidney function, and other cardiovascular risk factors.
Certain patients may require additional cardiac imaging or coronary evaluation depending on their symptoms and risk profile. Your cardiologist will explain why a particular test is being recommended and how the results may influence your treatment plan.
Where clearance identifies something that raises your risk, the useful response is to improve it rather than simply to document it. That may involve:
Our objective is to give your surgical team a clear, timely answer — and where possible to make you a lower-risk patient before you reach the operating room.

Surgical dates are difficult to move, so preoperative assessments are prioritized. Our aim is to give your surgeon a clear answer without avoidable delay, and to arrange any necessary testing promptly rather than pushing the date back.
