-- Heart attack phone call

Heart attack phone call

A team of scientists is currently working on an implant that swims around in your blood stream and gives you a phone call 2 weeks before you're about to have a heart attack

"The 14mm device measures up to five indicators, including proteins like troponin, that show if and when a heart attack has occurred. Using Bluetooth, the device can then transmit the data to a smartphone for tracking. "

Implant gets stuck in heart valve.

Causes heart attack.

Troponin only elevates AFTER an MI, I don't see how they would use that to predict an MI. This sounds stupid.

Can a heart attack be prevented [how][?]

People have minor heart attacks with out realizing sometimes and recover with out having sought medical attention, though usually this means they are just around the corner from an even larger one.

Depends on the extent of the cardiovascular disease. By altering modifiable risk factors like diet, exercise, stress, and not smoking, a person greatly reduces their chances of having a heart attack.

You can't fight genetics though, and if there is extensive family history of cardiac disorders and vascular disease, a person might be fucked anyway. Or if a person is born with valve problems, etc.

I just find the idea of a "heart attack alarm" so stupid. I mean, if a person is already identified/diagnosed as at risk, they are basically a ticking time bomb. You can't ever really know exactly when it's going to happen. It just takes the right combination of already poorly functioning arteries and cardiac tissue combined with a stressful event and you're fucked.

Current diagnostics are already pretty damn good at telling a person how fucked they are - bloodwork that checks stuff like cholesterol, metabolic function, etc., imaging like an echocardiogram or even better an angiogram, and also stuff like stress tests, etc., etc.

People just want an easy answer I guess, when it still all comes back down to lifestyle.

Troponin elevates after a fresh MI, peaks, and then falls back to normal again. It doesn't stay elevated forever.

Sometimes you can "see" an old MI on a 12 lead ECG by visualizing what is called a "q wave". But again, not everyone will have those ECG changes.

Which is where a device like this would be useful because it'd catch a heart attack that someone might just ignore as really bad indigestion or something else they think is benign.

Lol, they don't elevate immediately either. By the time you would notice an elevated troponin the damage is already happening. Chest pain or pressure, cool clammy skin, nausea - THOSE are your heart attack alarms.


edit: no yeah, I see what you're saying now. Yeah that would definitely be beneficial.

Yea but most people are idiots...

Yep that's true...refer to my edit.

Would be good for women, too, who often present with different symptoms.

Oh wait, just an email, nm
