Heart attack

Heart attack is a condition when the damage suffered by the heart muscle (myocardium) due to very sudden decrease in blood supply to it. Reduced blood supply to the heart suddenly can occur when one of the coronary artery blockage was for some time, either due to spasm - coronary artery mengencangnya - or akibar blood pergumpalan - thrombus. Sections of heart muscle that is usually supplied by a pulse which terblokade stop functioning properly immediately after splasme subsides by itself, the symptoms disappeared completely and heart muscle 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 permanently damaged. Muscles of the dead is called infarction.
 
Symptoms of Heart Attack
These symptoms can be different for each person. A heart attack may begin with pain that is unclear, vague discomfort, or chest tightness in the middle. 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 should undergo ECG examination for other reasons that may not be related. On the other hand, a heart attack may bring the worst pain ever experienced - extraordinary tightness or feeling pinched in the chest, throat or stomach. Can also heat or cold sweat, foot pain once and a sense of fear that the end is approaching. Also may feel more comfortable when sitting than when lying down and breathing is so crowded that may not be relaxed. Nausea and dizziness and even vomiting, and even more of that when it comes to collapse and faint.
There are some more specific symptoms, including:
* Pain. If the muscle does not get 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 a feeling of chest crumpled, 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 who experience 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 the result of the influx of fluid into the air cavities in the lungs (pulmonary congestion or pulmonary edema). * Fatigue or tiredness. If the heart is not pumping effectively, the flow of blood to muscles during activity will decrease, causing the patient to feel weak and tired. These symptoms are often mild. To overcome this, patients typically reduce their activity gradually or think this phenomenon as part of aging. * Palpitations (heart palpitations) * Dizziness and fainting. Decrease in blood flow due to rate or heart rhythm is abnormal, or because of poor pumping ability, can cause dizziness and fainting.
Early Warning Signs
However, one of the 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 is so subjective and so subtle, so that even doctors who are trained to objectively measure things can still be ignored.
Diagnosis
Based on perceived symptoms, a doctor can make a rational estimate of whether the symptoms suggest a heart attack or not. His suspicion may be reinforced by the appearance of the patient, the level of blood pressure and heartbeat sounds. Your doctor will probably send it to the ECG examination and blood test, but when still feel the pain, the doctor will probably give an injection penghilangrasa 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 not show signs of heart attack and possibly the examination should be repeated. Sometimes a second test still shows no change, and during this case, 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 this enzyme in part direct to rise, but subsequently these enzymes quickly break down and therefore no longer detectable after a day or two days, there is a new enzyme that is released several hours or several days later to stay in the blood for several days or even a few weeks
10 assumption wrong about heart disease
1. Heart disease only occurs in obese people only 2. Heart disease can not be the child or young person 3. Women free of heart disease 4. Heart disease is only one kind of 5. His heart was healthy, 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 shocked 10. Heart disease rises because often eat banana menu
Risk Factors of Coronary Heart Disease
* Entering the age of 45 years for men.
It is important for men to realize their vulnerability and take positive action to prevent future heart disease.
* For women, entered the age of 55 years or premature menopause (as a result of the operation).
Women began following the men in terms of risk of heart disease after menopause.
* History of heart disease in the family.
History of heart attack within the family is often a result of abnormal cholesterol profiles.
* Diabetes.
Most people with diabetes die not because of increased blood sugar levels, but because the condition of their heart complications.
* Smoking.
Drai heart disease risk equivalent to smoking 100 pounds overweight - so it is not possible to equate the two.
* High blood pressure (hypertension). * Overweight (obesity).
Central obesity (belly fat) is a form of obesity. Although all obese people tend to have an increased risk of heart disease, people with obesity was even more so.
* Bad lifestyle.
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 may be life-threatening heart arithmias.
