Heart attacks have been one of the leading causes of death in the US for many years, and very often, symptoms which could have been spotted well-in-advance go unnoticed. You may perhaps be familiar with the classic signs: a heavy sweat, clutching of the left arm, pain in the chest, and so on. But sometimes signs of a heart attack are not so obvious, particularly amongst women, who often don't seem to realize what's happening to them, or appreciate the seriousness of the situation, until it is too late.
Whatever the symptoms may be, do not wait until it's too late. Be aware of what changes are taking place in your body and take necessary precautions - being alert will help save a life, whether it be your own, or a friend's.

What is happening to the body in the process of a heart attack
During a heart attack, the supply of blood to the heart is suddenly blocked, usually by a blood clot, which happens due to the build-up of plaque in the coronary arteries. Consequently, this build-up causes a severe loss of blood supply to your heart, which then causes a heart attack.
There are two main types:
Sudden: A person may or may not have had any symptoms in the past. All of a sudden, plaque ruptures, which triggers a chain of events and a sudden heart attack.
Gradual: This results from a gradual progression of coronary disease. In these patients, an artery narrows over time. Once it has narrowed down to more than 70 percent, a number of warning symptoms will start to show, possibly even months ahead.
Therefore knowing the warning signs of a heart attack today, can help you or someone you know and love survive tomorrow. The sooner you recognize the symptoms and get treatment, the better.
The symptoms can occur for months or even longer sometimes, and the spectrum of symptoms is very wide.
Spot the signs well in advance
1. Difficulty breathing, especially a shortness of breath
When blood flow to the heart decreases, your lungs will feel the effect as well, as not enough blood gets pumped to your lungs, thus restricting your airflow and causing a shortness of breath. This can become an issue if you can't catch your breath even when sitting still and thus warrants an immediate check-up.
2. Constant tiredness and drowsiness
Restricted blood flow to the heart may give you an unshakable feeling of fatigue. This usually results from a sizable buildup of plaque in your arteries that carry blood both to and from your heart. This is concerning if you find it especially difficult to get up from your chair to go into the kitchen. Something this simple may feel as challenging as having to run a marathon.
3. Dizziness and lightheadedness
Poor blood circulation will limit your blood flow to the brain. Whilst dizziness and lightheadedness can be mistaken for many things, it is an especially common sign of a heart attack amongst women.
4. Breaking out into a cold-sweat and feeling weak
Suddenly breaking out into a cold sweat is another sign that should be taken seriously, particularly when paired with a feeling of weakness. This occurs because your arteries have continued to narrow, restricting the blood flow throughout the entire body.
5. Chest pressure and pressure in other parts of the body
Chest pressure is perhaps one of the most obvious symptoms of a heart attack and is often a clear indication that a heart attack is about to happen. However, most people tend to ignore the tight feeling or chest pain, believing that it is nothing serious. Women should pay particular attention to this feeling of pressure or mild discomfort if it occurs anywhere in the chest, not just on the left side where your heart is.
Feeling a mild to severe pain or sense of pressure in other parts of your body, such as your stomach, shoulder, arm, throat or jaw are symptoms which should not be ignored.
6. Cold and flu symptoms
People have also recorded the development of cold and flu symptoms prior to a heart attack. Symptoms of nausea and vomiting or stomach pain should also be looked upon with a watchful eye, particularly amongst women, who often mistaken these symptoms for indigestion or stomach flu.
What to do in the event of a heart attack
If you suspect that you are having a heart attack, here's a guide on what to do and what not to do.
Call emergency services immediately. Don't book an appointment with your cardiologist or doctor.
The sooner you call emergency services, the better your chances of survival. Every minute of delay makes death or serious heart damage much more likely.
Prevention is always best
Simple lifestyle changes can help diminish your chances of a heart attack in the future. Heart attacks can be preventable as illustrated in these six habits.
In a study conducted in the Netherlands on almost 18,000 men and women without heart disease, individuals were tracked for up for up to 14 years. More than 600 of the group had heart attacks in this period, and some even died. The study conculded that if people followed these four simple steps, they would be able to lower their risk of heart attacks by 67%.

How to Digitally Record/Video a UFO sighting:
Como registar digitalmente ou gravar um vídeo de um avistamento de um UFO:
Stabilize the camera on a tripod. If there is no tripod, then set it on top of a stable, flat surface. If that is not possible lean against a wall to stabilize your body and prevent the camera from filming in a shaky, unsteady manner.
Estabilize a camera com um tripé. Se não tiver um tripé, então coloque-a em cima de uma superfície estável. Se não for possível, então encoste-se a uma parede para estabilizar o corpo e evitar que a camera registe de maneira tremida e instável.
Provide visual reference points for comparison. This includes the horizon, treetops, lampposts, houses, and geographical landmarks (i.e., Horsetooth Reservoir, Mt. Adams, etc.) Provide this in the video whenever is appropriate and doesn’t detract from what your focus is, the UFO.
Forneça pontos visuais de referência para comparação. Isso inclui o horizonte, cimo das árvores, postes de iluminação, pontos de referência geográficos (como o Reservatório de Horsetooth, Mone Adams, etc) Forneça esses pontos no vídeo sempre que for apropriado e não se distraia do que é o seu foco, o UFO/a Nave.
Narrate your videotape. Provide details of the date, time, location, and direction (N,S,E,W) you are looking in. Provide your observations on the weather, including approximate temperature, windspeed, any visible cloud cover or noticeable weather anomalies or events. Narrate on the shape, size, color, movements, approximate altitude of the UFO, etc and what it appears to be doing. Also include any unusual physical, psychological or emotional sensations you might have. Narrate any visual reference points on camera so they correlate with what the viewer will see, and thereby will be better able to understand.
Faça a narração do vídeo. Forneça pormenores sobre a data, hora, local e direcção (Norte, Sul, Este, Oeste) que está a observar. Faça observações sobre as condições atmosféricas, incluindo a temperatura aproximada, velocidade do vento, quantidade de nuvens, anomalias ou acontecimentos meteorológicos evidentes. Descreva a forma, o tamanho, a cor, os movimentos, a altitude aproximada onde se encontra o UFO/nave, etc e o que aparenta estar a fazer. Inclua também quaisquer aspectos pouco habituais de sensações físicas, psicológicas ou emocionais que possa ter. Faça a narração de todos os pontos de referência visual que o espectador irá ver e que, deste modo, será capaz de compreender melhor.
Be persistent and consistent. Return to the scene to videotape and record at this same location. If you have been successful once, the UFO sightings may be occurring in this region regularly, perhaps for specific reasons unknown, and you may be successful again. You may also wish to return to the same location at a different time of day (daylight hours) for better orientation and reference. Film just a minute or two under “normal” circumstances for comparison. Write down what you remember immediately after. As soon as you are done recording the experience/event, immediately write down your impressions, memories, thoughts, emotions, etc. so it is on the record in writing. If there were other witnesses, have them independently record their own impressions, thoughts, etc. Include in this exercise any drawings, sketches, or diagrams. Make sure you date and sign your documentation.
Seja persistente e não contraditório. Volte ao local da cena e registe o mesmo local. Se foi bem sucedido uma vez, pode ser que nessa região ocorram avistamentos de UFOs/naves com regularidade, talvez por razões específicas desconhecidas, e talvez possa ser novamente bem sucedido. Pode também desejar voltar ao mesmo lugar a horas diferentes do dia (durante as horas de luz)para ter uma orientação e referência melhor. Filme apenas um ,inuto ou dois em circunstâncias “normais” para ter um termo de comparação. Escreva tudo o que viu imediatamente após o acontecimento. Logo após ter feito o registo da experiência/acontecimento, escreva imediatamente as impressões, memórias, pensamentos, emoções, etc para que fiquem registadas por escrito. Se houver outras testemunhas, peça-lhes para registar independentemente as suas próprias impressões, pensamentos, etc. Inclua quaisquer desenhos, esbolos, diagramas. Certifique-se que data e assina o seu documento/testemunho.
Always be prepared. Have a digital camera or better yet a video camera with you, charged and ready to go, at all times. Make sure you know how to use your camera (and your cell phone video/photo camera) quickly and properly. These events can occur suddenly, unexpectedly, and often quite randomly, so you will need to be prepared.
Esteja sempre preparado, Tenha sempre uma camera digital, melhor ainda, uma camera vídeo consigo, carregada e pronta a usar sempre que necessário. Certifique-se que sabe como lidar com a sua camera (ou com o seu celular/camera fotográfica) rápida e adequadamente. Esses acontecimentos podem acontecer súbita e inesperadamente e, por vezes, acidentalmente, por isso, necessita estar preparado.
