> There was hope that the Japanese would figure out something. 25 years later, they haven't. They've built up their safety net and put money into infrastructure projects, so that fewer people are suffering. That's the best they could come up with.

Improved safety net and infrastructure projects so fewer people are suffering? Sounds terrible. Please don't sign me up. /sarc

Seriously, what is wrong with improving the safety net and infrastructure projects? It's far better than the solutions being tried in the west, i.e. high unemployment and the gutting of social safety nets in the name of austerity. Once we can at least match Japan, then we can consider better still models of dealing with a lack of demand for labour, e.g. Basic Incomes or Job Guarantees (or whatever else).
Here's the thing - people experiencing a heart attack can have any combination, or none of the symptoms. So here's some of the symptoms, bearing in mind that they may or may not apply to any given situation.

Chest Pain
The first and most obvious sign is chest pain. It may be radiating down your left side (jaw/arm). It is generally described as a crushing pain. This symptom is less likely to occur for women or people with diabetes. If the chest pain is not relieved by resting (i.e. sitting down), it points towards a heart attack.

Shortness of Breath
As a body attempts to bring more oxygen into the body faster (because your heart isnt perfusing efficiently anymore), breathing will become faster and more shallow.

Pulse - Rapid, Weak
You should take your pulse a few times a year to get a baseline of what it's normally like. During a heart attack, it can become faster and weaker. However, this is relative - your pulse may normally be weak. This is why it is important to have a baseline.

Nausea, Dizzyness, Sweating, Weakness
These physical symptoms by themselves are usually not a concern (they happen with many sorts of illness really) but in combination with the above can be a warning sign.

In any discussion about heart attacks, it's important for you to understand the risk factors: http://www.mayoclinic.org/diseases-conditions/heart-attack/b...

If you're high risk and are suffering from the above symptoms, its always advisable to err on the side of caution and call the emergency services. In fact, if you're at all worried, just call.

There are some things you can do to help yourself during a heart attack:
1) Call emergency services.
2) Make sure emergency services can access you, especially if you're on your own. Unlock door, etc.
3) Half sitting position. Place your back up against a wall and sit with your knees raised.
4) Take an aspirin. This will thin your blood and relieve pressure on your heart.
5) Try control your breathing.
6) Try not to worry (yeah, I know, this is a hard one).

Regarding the "branding" - we've added the logo and a little text "built on ampoll.com" for our poll images so users know where the poll results are coming from. Other than that, we're trying to keep it minimal and not include too many intrusive branding to the pages.
This is a commendable goal, but I feel like it is all too tempting to focus narrowly on one disease and ignore a more holistic approach towards addressing the underlying problems. I have travelled to many countries in Africa and the big difference between countries that are sucessful in addressing malaria and others that are not are having better health systems and trained health workers. Giving out bed nets and spraying has limita. There are a lot of interesting techologies that may one eradicate malaria such as a vaccine or genetically modifying the mosquitos, but it is too short sighted when looking at the problem holistically.

Too often donors are tempted to focus on a single disease because it is much easier to measure progress and it is easier to "sell" to the public. But when you dedicate so much resources towards a single disease you're distorting the health system, and it becomes more susceptible to shocks like Ebola.

Amazing response. Answered question, provided additional caveats, and even background information! Thank you, this was of interest to me and very helpful.
Thanks for your response. I was always curious about something. My father inlaw was admitted a few years ago for bypass surgery. Upon inspection, they found (I'm doing this from memory so apologies if I get some of the numbers wrong) that 4 of his arteries were partially blocked, some up to 85%. In fact, his body produced a natural bypass on it's own because one artery was so clogged up (it literally created new connections to bypass the clog albeit much smaller then the original)!

My question is why can't we detect this high level of blockage much earlier (as in with a physical). Are the tests too intrusive or too expensive to recommend that the test(s) be performed periodically (eg maybe every 5 years after 30 or 40?)

Thanks!

Distributed Graph Processing in Neo4j
A century ago we had the Great Depression, followed by a major application of regulation, followed by the biggest and longest boom in middle-class history in the US.

In the 80s we started massive deregulation including killing Glass-Steagall, opening up banks to so destroy the global economy that we're having this discussion today.

Your history of regulation and relative wealth is backwards.

Edit: I'll acquiesce that the tax code is laughable, but mostly in how upper-class income tax levels are half what the middle class pays.
I disagree.

I saw a definition of being rich as "never having to worry about money". Now take being poor as "always having to worry about money".

Doesn't matter if you have got a widescreen TV. If you sell it off you may eat better for a few weeks, but after that you will still be in the same situation, in constant worry about money.
Not claiming to have much understanding about any of this stuff, but here's his comment from the link:

"+retrotails prower I'm sure +Dirk Hohndel would like an Atari ST port but once you get past 286 there are better OS to run. For m68k you have to deal with the lack of segmentation or banking in most cases (so vfork not fork), but if you can do that then given you've usually got real DMA I would have thought 2.11BSD/RetroBSD a far far better place to start, or even ucLinux. Many of the 68K platforms are also blessed with other open but non-Unix OS's especially the Atari where basically all the underlying OS code you need is nowdays available in a free form (eg FreeMiNT/XaAes - which is even uses rpm)

Some of the key assumptions in UZI and thus in Fuzix really stop making sense if you have a 32bit system or you have good offloaded I/O. I'm not entirely sure those assumptions don't break down by 286 to be honest. However 286 protected mode is so wonderfully demented and feature filled it has to be done.﻿"
> 10 minutes of ultrasound to diagnose a serious illness can cost several hundred dollars in the USA

Chances are only a small portion of that is the cost of the ultrasound machine.
Because a simple walk down an average street nearly anywhere in the country strongly indicates otherwise. In science, we like to imagine that we'll begrudgingly discard our theories in the face of a single contradictory fact. Economists don't even seem to pretend that's a thing they'd ever do.

There are some 50-60 million people living in poverty in the US. Schools don't have books or desks. People are quite literally fighting insurance companies for their lives on a daily basis. That's quite a lot of demand out there for pretty basic things. There are staggering numbers of unemployed and underemployed people out there as well, so we're not hurting for supply-side capacity either.

There's simply more profit to be made by "investing" capital in playing financial games than there is in meeting actual demand. We can quibble about whether this is a failure of capitalist theory or a failure caused by too much regulation, or probably a dozen other claims. But whatever the case, it's a pretty cut and dried case of the bleeding obvious that we're not at capacity in our economic system.
I thought I expressed myself reasonably clearly. The web is currently slowly centralizing and turning into Facebook. Google could fight this trend by using SRV records for HTTP/2. If, otherwise, this trend continues, Google will eventually have nothing in the open web to index, and will therefore get no value from selling ads in their search service. Therefore, Google is doing itself a disservice by not using SRV records in HTTP/2.

I further speculated about the reasons Google might have for acting the way the do – i.e. not supporting SRV records. I proposed two reasons: First, SRV records do not solve any problem which Google has not already solved for themselves, and they do not want anybody else to simply get the solution for free, since that would devalue their previous investment. Second, Google assumed that they would be the ones that the Web would centralize into, and even since Facebook has appeared, Google created Google+ and tried to push it as a centralization point, using every pressure point they could muster (YouTube, etc.) to make this happen. If they could make this happen, they also would not benefit from a more decentralized web as would be enabled by SRV records in HTTP/2.

If it can accurately monitor your heart beats, then I believe it should be able to identify patterns that signal an impending heart attack. I'm not a doctor tho, so don't take me too seriously.

Once you realised you were having a heart attack, what did you think about?
For me this is a real issue. I have genetic high cholestrol (I'm on 80 mg lipitor) and I suffer from gastric reflux and excessive gas. I've been to ER twice when I thought I was having a heart attack but it was just bad gas/heartburn :( Now I'm sure to dismiss the real attack...
> I said unwarranted. As in, not justified and not related to his recent anecdote.

[Sorry. I couldn't believe you intended the correct meaning of unwarranted and instead meant "unjustified" in an entirely different sense.]

As he pointed out, if tip4commit tried to do what it was doing with anything other than a crypto currency, it'd have to change its ways or be shut down rather quickly; either way, he'd not have to deal with the problems it presents.

That may not be the most central point to his anecdote, but it is certainly a "warranted" point in the discussion.

To take an ECG tracing you need at least 3 points of contact with skin around the body (a hospital ECG has 9 leads attached to the body from which the machine calculates 12 waveforms of electrical activity). A watch based mechanism would not have the capacity to do this and even a 3 lead ECG would not be considered sufficient as it would miss too many changes.

I therefore believe that a smart watch would not with any current technology be capable of detecting a heart attack.. Pulse and heart rate are simply not useful (neither sensitive or specific) criteria for detecting MI's

For further reading on the physics of an ECG hit up

Edit: my ECG knowledge is a bit rusty- 2 points of contact is enough to produce a single waveform reading...

What's the number one thing people who run web servers are concerned about?

It's not performance.

It's not customer experience.

It's reachability.

When a person with a browser clicks, they have to receive the page they clicked on before anything else can happen. Seems obvious, right?

In order to do that, they need a web server that they trust. Most people opt for Apache, nginx or IIS. Which of those has well-tested and trustworthy HTTP/2 implementations?

> how good is your last laptop - is it good enough?

No, it is not.

My last "perfect for the moment" laptop was the latest G3 iBook (late 2002).

After that nothing as been "perfect" anymore. I went thought many "good" laptops but I have always found hardware glitches (NVidia card overheating), missing ports (dear Dell, where is the SD card reader?), proprietary ports (Samsung and its three proprietary ports for video out _on the same laptop_), annoying keyboard layouts, glossy and too wide screens, chargers with connectors that are produced only for six months, firmwares with weird-but-well-known bugs that will never be solved.... There is always something.

> and capitalism in particular are not a zero-sum game

Look at it this way. Money causes corporations to become powerful entities (through propaganda, lobbying, internal R&D, etc.), and this reinforces the loop. There is a selective component, in that competition leads to corporate casualties. In other words, capitalism causes agglutination of money. Hence, capitalism leads to some people becoming rich, and most people becoming poor (because they are now out of business).

The effect will be directly noticeable to people here on HN when Google invents strong AI, and puts every programmer in the nation out of business :)

The 1948-49 blockade was also fascinating moment. The Western parts of Berlin (at the time split between France, UK and USA) had their roads blocked off; rather than start getting supplies from the Soviet side and thus lose control over West Berlin, an airlift was instituted which did an amazing 200,000 flights to Tempelhof over 11 months. In comparison, Chicago ORD had 580,000 combined landings and takeoffs in the whole of 2014.

"We should teach future generations to give to charity"

We should encourage future generations to develop an alternative to the financial system that in many respects creates barriers to equality and progress in so many fields. It's tragic that eradicating a disease requires us to contribute 'tokens' to facilitate action - and if we don't contribute enough we will penalise sections of our population.

I like the idea of basic income, but I'm skeptical about how many problems it can actually solve. Your depiction almost makes it sound miraculous (with a bit of social romanticism), while ignoring the problems it could eventually create.
Apart form that we are a long way from having a serious discussion about it, as it's just too alien a concept for most people, including those who would need it.
it is a typo. should be 'combine' (because, the way it is now, the presence of the 'combine' argument serves no purpose).
Blockages of up to 90%, whilst considered 'critical', typically cause little in the way of symptoms.

The gold standard for detecting vessel blockage is angiogram- puncture the femoral or radial artery, feed a catheter to the top of the aorta and squirt some dye and then watch it on X-ray.
This has risks however- risks of rupturing artery walls, causing bleeding and bruising, and can be expensive. So it is not routinely done: in fact it is only indicated if a patient presents with a MI (gold standard is to have the patient in angio lab within 90 minutes of onset of symptoms, which is great because if they are they can generally reverse the blockages with stenting before long term damage occurs), or if a patient has a positive stress test.

CT angiograms are becoming more common but still not commonly used due to decreased sensitivity.

If a patient is believed to have risk factors for artery disease then they may be given a exercise stress test- hook up to an ECG, get on a treadmill and if there are changes consistent with vessel ISCHAEMIA (as opposed to infarct), then an angiogram will usually be scheduled.

For patients too unwell for a exercise stress test nuclear medicine stress tests can be performed.

And finally in patients who have blockages in more than 3 arteries, the gold standard is still (for the time being) coronary artery bypass grafting.

I guess to summarise, the reason we can't detect it earlier is because generally we require invasive means to do so and invasive tests carry risk to the patient that are hard to justify for screening purposes.
Perhaps in the future CT angio may be made more readily available, the scanners keep getting better and better and resolution increases all the time however you always want to minimise a persons radiation dose as for every 3-400 people scanned you can cause one instance of cancer...
