Dr... THAT'S MY MACHINE! Not only did I build those GE Scanners in the factory for 10 years, I also maintain them now for my hospital network! Thank you so much for all you do. I shared this with all of my Biomed friends to give them a better idea of why I do what I do :)

@SeaStarGazer1111 5 месяцев назад

@Dr. Pradip Jamnadas you look so different w/o your facial hair!!! I've had two CCTA's , both showing zero blockages. They were done because I had chest pain, which was determined to be unrelated to the heart. My cardiologist only reported to me on the zero blockages, not all the other possibilities. Maybe because nothing else showed. My Dad had ASHD and passed at the age of 57 from a clot in the aorta. His mother passed from cardiac arrest, as did my half brother. So I want to be sure I'm not next in line, lol.

Traditional CT is like taking pictures and this new technology is like taking videos and allow one to see it 3 dimensionally.

@sheddkkhan6758 2 года назад

@jobrown8146 Год назад

I think the stress test is the preliminary test and then if needed the CT angiogram is performed so this is not unusual. I am not able to run on a treadmill to do a stress test so the specialist is sending me straight for the CT angiogram. My husband had an angiogram done in the early 1980s and I think they inserted a camera through a vein in the groin area.

I should be very interested to know why you say cryptically "in today's world more and more patients are going to be getting a CT scan". Why is that? Is that because people are tending to live longer? the technology is becoming more acucrate and useful? becoming cheaper? more people are having heart problems? doctors and cardiologists are more aware of early warning symptoms? people are making more money out of it even if its not necessary? a combination of various of these factors?? I'd be intrigued by an answer to that question

I experience my angina at the exact epicenter of my attacks, the left arm between the bicep and triceps where there is a cluster of nerves and such. I can still feel it from the outside, it feels like I'm pressing on a bruise. I get pain I assume is my body's version of angina at that point when I over exert myself, when I am underhydrated and exert myself, and during some anxiety episodes. I have edema. I can feel circulation problems in my legs. I have varicose veins and broken capillaries. It has been this way since my first cardiac episode in 2009.

Probably just to make sure you are not rushing to get there at the last minute, which would raise your heart rate. I had the test a little over a week ago and my cardiologist urged me to leave plenty of time to get there so I wouldn't be stressed. They want your heart rate to be no more than 60 beats per minute, and will give you a drug to slow it down if necessary. If it is necessary, it may take time for the drug to work, but it wasn't necessary in my case.

How do we get rid of the calcium

@pradipjamnadasmd 3 года назад

You cannot eliminate what has already deposited into the wall, you can stabilize it so it does not rupture and cause a heart attack, and you can stop the progression of more calcium buildup through my prevention program. Serial coronary calcium scans every two years can document the calcium score and efficacy of prevention measures.
