Blood Pressure Monitoring (24 hrs)
What is Ambulatory Blood Pressure Monitoring
Ambulatory Blood Pressure Monitoring is a test where your blood pressure and heart rate are taken at a fixed time interval for 24 hours while you carry on with your daily activities.
It is particularly useful for patients with high blood pressure as it helps your doctor determine if your blood pressure medications are effective. It is also used to monitor borderline hypertension, young hypertension and poor blood pressure control. This 24-hour monitoring allows the doctor to study the variations of your blood pressure throughout the day.
Preparations before the test
Take a bath and wear loose fitting clothing before coming for the appointment
No fasting is required
No admission is required
You may continue with your current medication.
You will need to return the device the next day.
How is the test done
The medical technologist will first take your height and weight to determine your body mass index (BMI). Blood pressure will also be measured on both left and right arm to determine which arm has a higher blood pressure. Thereafter, you will proceed to a private room to have the actual portable blood pressure machine fixed onto your arm.
The medical technologist will measure the length and circumference of your arm to provide you with the correct blood pressure cuff for the portable blood pressure machine. The staff will then proceed to measure three manual blood pressures and after recording all the three readings, the machine is calibrated for your use. During daytime, the machine is programmed to measure your blood pressure every 20 minutes of the hour. The frequency of measuring will be reduced to every 30 minutes of the hour after 10pm. You are also required to note down the time you go to bed and the time you wake up in the diary provided to you.
During this period, you can continue with your normal daily activities. However, you must not remove the blood pressure cuff. You are also advised not to shower during the recording period. To ensure accuracy of the recorded results, you are advised also not to bend your arm when the device is taking your blood pressure.
Magnetic resonance imaging is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease. MRI scanners use strong magnetic fields, electric field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays and the use of ionizing radiation, which distinguishes it from CT or CAT scans.
An MRI helps a doctor diagnose a disease or injury, and it can monitor how well you’re doing with a treatment. MRIs can be done on different parts of your body.
CT Angiogram + Calcium Score
What is CT Angiogram and Calcium Score?
Angiography is a medical test to diagnose and treat medical conditions. A cardiac CT scan for calcium score is for obtaining information about the presence, location and extent of calcified plaque in the coronary arteries which are the vessels that supply oxygen-containing blood to the heart muscle. Calcified plaque results when there is a build-up of fat and other substances under the inner layer of the artery. This material can calcify which signals the presence of atherosclerosis, a disease of the vessel wall, also called coronary artery disease (CAD). People with such disease have an increased risk for heart attacks. In addition, over time, progression of plaque build-up (CAD) can narrow the arteries or even close off blood flow to the heart. The result may be chest pain, sometimes called a heart attack.
Because calcium is a marker of CAD, the amount of calcium detected on a cardiac CT scan is a helpful prognostic tool. The findings on cardiac CT are expressed as a calcium score. Another name for this test is coronary artery calcium scoring.
How should I prepare?
No special preparation is necessary in advance of a cardiac CT examination. Medications should be consumed as prescribed. Avoid caffeine and smoking for four hours prior to the exam. Women should inform their physician and medical staff if there is any possibility that they may be pregnant.
How is the procedure performed?
You will be positioned on the CT examination table. Electrodes will be attached to your chest and to an ECG machine that records the activity of the heart. This makes it possible to record CT scans when the heart is not actively contracting.
The table will move quickly through the scanner to determine the correct starting position. The table will then move slowly through the machine as the actual CT scanning is performed.
Patients will be asked to hold their breath for a period of 10 to 20 seconds while images are being recorded. The entire procedure including the actual CT scanning is usually completed within 10 minutes.
