Non invasive cardiology

Non-invasive cardiology is a specialized division that concentrates on diagnosing and treating heart disease using exterior diagnostics rather than invasive methods. Compared to invasive methods, non-invasive methods do not require the insertion of equipment, needles, fluids, or other tools into the body. A non-invasive cardiologist aims to prevent and manage cardiac conditions through medication and dietary modifications.

The Non Invasive Cardiology Department at Aster is one of the best in its field of non-invasive procedures and diagnostics. With the superior quality testing equipment, Aster is known to provide the best management protocols and services as follows:

  • Nuclear cardiology: This is a non-invasive test of cardiovascular diseases using various imaging techniques that may involve radioactive materials.
  • Echocardiography: This technique uses ultrasound waves to produce images of the heart and structures around it to detect infections, structural abnormalities, and how well the heart pumps blood.
  • Cardiac electrophysiology: Heartbeat-generating electrical currents are studied and tested in cardiac electrophysiology.
  • Stress tests: In this, the cardiologist will test the heart condition during monitored exercise. These exercises provide the cardiologist with more information about cardiac function under stress.
  • Heart monitors: Holter monitors and cardiac event recorders are other names for heart monitors. Heart monitors record the heart's electrical activity on a tape for a predetermined period.
  • CT scans: These scans generate images a cardiologist can study to check for atherosclerosis and heart disease.

After identifying risk factors or pre-existing diseases, the cardiologist might suggest medication and lifestyle modifications to improve the heart's health.

Facilities - Diagnostics & Amenities

Aster provides you with the state-of-the-art equipment and techniques to help diagnose your cardiac condition. At Aster, we use modern day technology to aid doctors in diagnosis of cardiac ailments and help them manage patients with ease. The easily available tests and amenities at Aster will help you lead a healthy life without having to worry about your treatment protocol.

The diagnostic tests provided under non-invasive cardiology at Aster Hospital include:

  1. 2D/3D Echo: 2D/3D echocardiograms are non-invasive procedures done to assess the heart's structure and function. It helps diagnose congenital heart diseases, heart valve dysfunction, blood clots, or tumours. During the procedure, a transducer (a microphone) emits sound waves at a frequency that cannot be heard.
  2. 2D/3D colour doppler: The doppler is a diagnostic ultrasound that employs sound waves to produce images of the inside of the body, including the heart, to look for different medical disorders. The heart and valves' size, structure, and function are assessed using 2D/3D doppler echocardiography with colour flow. In addition, blood clots, malfunctioning valves in the leg veins, and blocked arteries can be diagnosed with 2D/3D colour doppler. The body's various components reflect sound waves from a portable probe. A transducer detects these reflected sound waves' electric impulses, subsequently translated into two-dimensional visuals that a medical specialist can analyse.
  3. CT coronary angiography: CT coronary angiography is a minimally invasive imaging procedure that examines the arteries that carry blood to the heart. The primary purpose of a CT coronary angiography is to look for blocked or constricted heart arteries, like aneurysms, atherosclerosis, coronary artery disease, and pulmonary embolism. A technician will insert a numbing substance before placing an IV in the hand. This IV has a dye (contrast) flowing through it. The dye makes blood vessels more visible on CT scans.
  4. Contrast transesophageal echocardiography: Contrast transesophageal echocardiography is a unique kind of echocardiography. It is typically carried out when your doctor wants to examine your heart in more detail to determine developing blood clots. It is commonly done for detecting thrombi atrial fibrillation in patients. It uses high-frequency sound waves (ultrasound) to analyse the heart's structural components.
  5. Ambulatory BP monitoring: The blood pressure can be continuously monitored for 24 hours using ambulatory blood pressure monitoring. Whether awake or asleep, the monitoring captures your blood pressure (BP) values through a 24-hour period. In ambulatory blood pressure monitoring, several measurements are collected continuously. In most circumstances, the gadget takes readings every 60 minutes at night and every 15 to 30 minutes during the day.
  6. Treadmill test or stress test: A treadmill test or stress test is used to assess exercise's effects on the heart. This test enables medical professionals to identify irregular heart rhythms (arrhythmias) and diagnose coronary artery disease. Additionally, it aids in your doctor's treatment planning for cardiac disease. The treadmill stress test is carried out in a designated lab under the supervision of a qualified healthcare professional. An ECG machine records the heart's electrical activity by attaching electrodes to the chest.
  7. Strain rate imaging: Strain rate imaging is a technique used in medical ultrasound to assess local or overall myocardial (heart muscle) deformation. The word "deformation" describes how the myocardium alters its size and shape throughout the cardiac cycle. The myocardium's distortion can be measured via strain imaging. Myocardial strain imaging assesses how well the heart muscle works using cardiac ultrasound. Speckle-tracking echocardiography, tissue doppler imaging, and cardiac magnetic resonance imaging (MRI) can all be used to quantify strain rate imaging.
  8. Head-up tilt test (HUTT): The HUTT test records your blood pressure and heart rate every minute. The head-up tilt test (HUTT) is an effective syncope diagnostic technique. On a unique, tiltable bed, you will be instructed to lay flat for five minutes. You'll gradually be raised to a 90-degree angle in your bed, almost standing upright. The test will continue for another 20 minutes or until you experience lightheadedness or fainting and your blood pressure or heart rate change.
  9. Holter examination: A tiny, wearable Holter monitor device captures the heart's rhythm. It is used to diagnose heart arrhythmias. Conditions such as heart block, dizziness, atrial fibrillation or other forms of arrhythmia are diagnosed by this test. At specific locations on the chest and belly, electrodes are attached. Wires connect the electrodes to the ECG machine. The heart's electrical activity can then be monitored, written down, and printed.
  10. External loop recorder: External loop recorder (ELR) is a portable battery-powered gadget that monitors and records cardiac activity for several days. This kind of constant observation aids in identifying aberrant cardiac rhythms, including atrial fibrillation, presyncope, unexplained syncope, and sustained palpitations. An external loop recorder is a heart monitor with electrodes attached to the patient to record the patient's surface ECG.

    What is non-invasive cardiology?

    Non-invasive cardiology refers to the use of imaging and diagnostic techniques to assess heart health without the need for invasive procedures, such as surgery. Common non-invasive tests include electrocardiography (ECG), echocardiography, stress tests, TMT, MRI, nuclear imaging and Holter monitoring.

    Can non-invasive cardiology treat heart conditions?

    Non-invasive treatments such as lifestyle modifications, medication management, and certain therapies can be effective for specific heart conditions.

    What are the standard non-invasive cardiac tests?

    Some standard non-invasive cardiac tests include:

    • Chest x-rays
    • Electrocardiogram
    • Echocardiography
    • CT coronary angiography
    • BP monitoring
    • Treadmill test or stress test

    Can non-invasive cardiology diagnose heart conditions accurately?

    Yes, non-invasive tests can provide valuable information to diagnose heart conditions, assess heart function, and identify potential issues.

    Angioplasty – is it non-invasive?

    One of the most popular heart treatments is coronary angioplasty. The treatment is often performed safely in most people because it does not need large incisions in the body. This type of therapy is referred to as minimally invasive by doctors, but it’s not non-invasive.
