Bright and early this morning Karl went in for in for a Cardio/Nuclear Stress Test. This was ordered by his cardiologist to see if his heart and body are ready for exercise at cardio rehab.
The cardiac stress test is done with heart stimulation, either by exercise or with intravenous pharmacological stimulation, with the patient connected to an electrocardiogram (or ECG). Karl is going the IV route, along with having "myocardial perfusion imaging." A radiotracer is injected during the test. After a suitable waiting period to ensure proper distribution of the radiotracer, photos are taken with a gamma camera to capture images of the blood flow. Photos taken before and after exercise are examined to assess the state of the coronary arteries of the patient. By reviewing the amounts of radioisotope within the heart muscle, the test identify regional areas of reduced blood flow, if any.
On another note, Karl had a nice visit with his brothers the past week, and they have been helpful with projects like cutting hedges, plumbing, errands, allowing Penny to take some time out with the girls and just surrounding Karl with love. Keith will still be in town for another few days. Karl continues to walk without his walker and is ready to get moving with more therapy. He has enjoyed all the cards, calls and visits from friends. Thanks to everyone for the continued support!
