Recognize Symptoms of Heart Attack - Heart attack (in English: Myocardial infarction, acute myocardial infarction, MI, AMI) is the cessation of blood flow, although only for a moment, leading to the heart, and causes some heart cells to die.Heart disease is the number one cause of death in adults in the United States. Every year in the United States:
* 1.5 million people have heart attacks.
* 478,000 people die from coronary heart disease.
* 407,000 people experience a transition operation.
* 300,000 people undergo angioplasty.
Heart disease, stroke, and peripheral arterial disease is a deadly disease. Around the world, the number of people with this disease continues to grow. These three categories of disease can not be separated from the unhealthy lifestyle that many will follow the changing pattern of life.
Trigger factors of heart attack is smoking, eating foods high cholesterol, lack of exercise, supine exercise, stress, and lack of rest.
Introduction of the Heart
The heart is a muscular organ, conical, hollow and with its base above and below the peak. Its apex (peak) to the left. Heart weight approximately 300 grams. So that the heart serves as an efficient pumping, heart muscles, the cavity top and bottom of the cavity must alternately contract. The rate of heartbeat or pulse-pumping action is controlled naturally by a "regulatory rhythm". It consists of a group in particular, called nodes sinotrialis, located within the walls of the right atrium. An electrical impulse is transmitted from the node into the second platform sinotrialis make them to contract simultaneously. Electric current is then passed on to the walls of the chamber, which in turn makes the ventricles to contract simultaneously. This period of contraction called systole. Furthermore, this period was followed by a short relaxation period - approximately 0.4 seconds - which is called diastole, before the next impulse came. Sinotrialus node produces between 60 to 72 impulses like this every minute when the heart is relaxed. Production of impulses is also controlled by a part of the nervous system called the autonomic nervous system, which works out of our desire. Built-in electrical system that produces contractions of the heart muscle called the heart rate rhythmic.
Risk Factors of Coronary Heart Disease
* Entering the age of 45 years for men.
It's important for men to realize their vulnerability and take positive action to prevent any future heart disease.
* For women, entered the age of 55 years or premature menopause (due to surgery).
Women began following the men in terms of risk of heart disease after menopause.
* History of heart disease in families.
A history of heart attack in the family is often the result of abnormal cholesterol profiles.
* Diabetes.
Most diabetics die not because of increased blood sugar levels, but due to complications of the condition of their heart.
* Smoking.
The risk of heart disease from smoking the equivalent of 100 pounds overweight - so it is not possible to equate the two.
* High blood pressure (hypertension).
* Overweight (obesity).
Central obesity (belly) is a form of obesity. Although all obese people tend to have an increased risk of heart disease, those with central obesity even more.
* Lifestyle bad.
A bad lifestyle is one of the root causes of heart disease - and replace them with physical activity is one of the most radical step that can be taken.
* Stress.
Many studies have shown that, when facing a tense situation, there can be life-threatening heart arithmias.
Heart attack is a condition when the damage suffered by the heart muscle (myocardium) due to very sudden decrease in blood supply to the heart muscle. Reduced blood supply to the heart suddenly can occur when one of the coronary arteries terblokade for a while, either due to spasm - coronary arteries to tighten - or blood clots akibar - thrombus. Section of heart muscle that is usually supplied by a pulse cease to function properly immediately after splasme subsides by itself, the symptoms disappeared completely and the heart muscle to function completely normally again. This is often called crescendo angina or coronary insufficiency. Conversely, if the blood supply to the heart stops altogether, the cells in question experienced a permanent change in just a few hours only and referred to the heart muscle is severely degraded or damaged permanently. Dead muscle is called infarction.
Symptoms of Heart Attack
These symptoms are usually different for each person. A heart attack may begin with a vague pain, vague discomfort, or tightness in the front center chest. Sometimes, a heart attack caused only mild discomfort at all so it is often mistaken for indigestion, or even escape the attention at all. In this case, the only way that allows the detection of a heart attack is when an ECG should undergo examination for other reasons that may not be related. On the other hand, heart attacks may bring the worst pain ever experienced - a remarkable tightness or feeling pinched in the chest, throat or stomach. It could also be sweating hot or cold, painful feet and a sense of fear that the end was approaching. Also may feel more comfortable when sitting than when lying down and breathing may be so crowded that can not relax. Nausea and dizziness and even vomiting, and even more of when to collapse and unconsciousness.
There are some more specific symptoms, including:
* Pain. If the muscles are not getting enough blood (a condition called ischemia), then the oxygen is inadequate and the result of excessive metabolic causes cramps or spasms. Angina is a feeling of tightness in the chest or squeezing chest feeling, which arises when the heart muscle not getting enough blood. The type and severity of pain or discomfort will vary in each person. Some people experience a lack of blood flow could not feel any pain at all (a condition called silent ischemia).
* Shortness of breath is a symptom commonly found in heart failure. Shortness is a result of the entry of fluid into the airspaces in the lungs (pulmonary congestion or pulmonary edema).
* Fatigue or tiredness. If the heart is not pumping effectively, the blood flow to muscles during activity will be reduced, causing the patient to feel weak and tired. These symptoms are often mild. To overcome this, the patient usually gradually reduce their activity or thought that these symptoms as part of aging.
* Palpitations (heart palpitations)
Dizziness & fainting. Decreased blood flow due to rate or abnormal heart rhythms or because of poor pumping ability, can cause dizziness and fainting.
Early Warning Signs
However, one very idea that a heart attack came like lightning in broad daylight. Heart attack is the culmination of a process of catastrophic damage that lasts a long time, which often involves emotional surprises, chaos physiological and mental fatigue. Early warning signs are so subjective and so subtle, so that even doctors who are trained to objectively measure everything can still be ignored.
Diagnosis
Based on the perceived symptoms, a doctor can make a rational estimate of whether the symptoms suggest a heart attack or not. Suspicions may be confirmed by the appearance of the patient, the level of blood pressure and heartbeat sounds. The doctor will probably send him to the ECG examination and blood test, but if still feel the pain, the doctor will probably give an injection remover pain before the examination. It's scary because the pain can be brought to the brink of a deeper, which can cause cardiac symptoms. The pain can also cause long-term psychological impact. The first ECG may show no signs of heart attack and that the examination may be repeated. Sometimes a second test still showed no change, and during this, the diagnosis will rely on blood tests. The heart, like all other body cells, contain special chemicals called enzymes. When heart cells are damaged, enzymes are released together with circulating blood flow. After a heart attack, levels of some enzymes is straight up, but then these enzymes quickly break down and therefore not detected again after a day or two days; there is a new enzyme that released a few hours or a few days later to stay in the blood for several days or even a few weeks.
10 misconception about heart attack
1. Heart disease only occurs in obese people alone
2. Heart disease can not be in a child or young person
3. Women free of heart disease
4. Heart disease is only one kind of
5. Healthy heart, could not have heart disease
6. No association with stroke
7. Heart disease is a hereditary disease
8. Heart disease can not be prevented
9. Heart disease because often surprised
10. Heart disease arise because often eat banana menu
