Heart attack (Myocardial infarction, United Kingdom: myocardial infarction, acute MI, AMI) is a blood flow has been stopped, even if only for a moment, which leads to the heart, and heart cells resulting in a death.
Heart disease, stroke, and peripheral arterial disease is a disease that is deadly. Worldwide, the number of sufferers of the disease is steadily growing. The third category of this disease do not escape from a less healthy lifestyle that much was done along with the shift in the pattern of life.
Factors trigger a heart attack is cigarettes, consuming foods high in berkolestrol, less motion, lazy to exercise, stress, and lack of rest.
The Introduction Of The Heart
The heart is a muscular organ, conical, hollow and with its base above and below. Apex (APEX) tilted to the left. Heavy heart roughly 300 grams. In order for the heart to function as an efficient muscle-pumping, heart muscles, upper and lower cavities cavity must be contacted in turn. Pulse rate-heart rate or working the pump is controlled naturally by a "rhythm". It consists of a group of specifically, called sinotrialis nodes, which are located inside the walls of the Foyer right. An electrical impulses transmitted from node sinotrialis to the second porch makes both contracts simultaneously. Electric current is then passed on to the walls of the room (s), which in turn make booths contracting simultaneously. This is called the systole period of contraction. The next period is followed by a short period of relaxation-approx. 0.4 seconds-which is called diastole, before the next impulse comes. Sinotrialus nodes produce between 60 to 72 such impulses per minute when the heart is relaxed. Impulse-impulse production is also controlled by a part of the nervous system called the autonomic nervous system, which works out of our desires. Built-in electrical system which produces contraction-contraction of heart muscle beirama called heart rate.
Risk factors of coronary heart disease
• Entering the age of 45 years for men.
It is important for men to be aware of their vulnerabilities and take positive action to prevent the arrival of heart disease.
• For women, entered the age of 55 or have early menopause (as a result of the operation).
Women began to catch up with men in terms of the risk of heart disease after menopause.
• A history of heart disease in his family.
History of a heart attack in the family is often a result of abnormal cholesterol profiles.
• Diabetes.
Most diabetics died is not due to increased blood sugar level, but due to complications of a heart condition.
• Smoking.
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 (pot belly) is a form of overweight. Although all obese people are likely to have heart disease risk, people with Central obesity moreover.
• Bad lifestyle.
Poor lifestyle is one of the root causes of heart disease-and replace it with physical activity is one of the most radical steps that can be taken.
• Stress.
Much research has shown that, when facing a tense situation can occur, arithmias heart that endanger lives.
A Heart Attack
A heart attack is a condition when the damage experienced by the heart muscle (myocardium) resulting from sudden very reduced blood supply to the heart muscle. A decreased blood supply to the heart suddenly can occur when one of the pulse coronary terblokade for a few moments, either due to the mengencangnya nadi spasme-coronary blood clotting or thrombus. Parts of the heart muscle that is usually supplied by the pulse stops functioning properly terblokade immediately after the splasme to take off by itself, symptoms gone thoroughly and heart muscle functioning completely normal again. This is often called the crescendo angina or coronary insufficiency. Conversely, if the blood supply to the heart of stalled altogether, the corresponding cells undergo a permanent change in just a few hours and the heart muscle termaksud decreased quality or damaged permanently. The dead muscle is called myocardial.
Symptoms Of Heart Attack
These symptoms are common to each person is different. A heart attack may be started with no apparent pain, discomfort, or a vague sense of tightness in the middle of the chest. Sometimes, a heart attack caused only mild discomfort so often misconstrued as bad indigestion, or even off of the attention at all. In this case, the only way that allows detection of a heart attack is when should undergo screening ECG for other reasons that may not be related. Other Dipihak, of a heart attack may present the worst pain I've ever experienced-a remarkable sense of tightness or feeling squeezed on the chest, throat or stomach. It could also procure sweat hot or cold, leg pain and a sense of fear that death is approaching. Also might feel more comfortable when sitting than when lying down and it is possible breath so crowded so it could not relax. The nausea and vomiting, dizziness and even got even worse when to make the site and passed out.
There are several more specific symptoms, including:
• Pain Relief. If the muscle is not getting enough blood (a condition called iskemi), the inadequate oxygen metabolism and the results lead to excessive cramping or spasms. Angina is a feeling of tightness in the chest or feeling chest scrunched, arising when the heart muscle is not getting enough blood. The type and severity of the pain or discomfort will vary on each person. Some people who experience a lack of blood flow can not feel any pain at all (a State called silent ischemia).
• Shortness of breath is a symptom that is commonly found in heart failure. Tightness is a result of the influx of fluid into air cavities in the lungs (congestion or edema pulmoner pulmoner).
• Fatigue or kepenatan. If the heart is not pumping, then effective blood flow to muscles during activity will be reduced, causing the sufferer to feel weak and tired. These symptoms are often mild. To fix it, the sufferer usually reduces its activities gradually or thought these symptoms as part of aging.
• Palpitations (heart palpitations)
• Dizziness and fainting. Decreased blood flow due to pulsation of heart rhythm or abnormal or because of a bad, pumping ability can cause dizziness and fainting.
Early warning signs
However, once the opinion that a heart attack came as a thunderbolt in broad daylight. A heart attack is the culmination of a process of disaster damage that lasts long, which often involves emotional surprises, physiological disorder and mental fatigue. Early warning signs are so subjective and so subtle, so that even doctors trained to measure anything objectively could still ignore it.
Diagnosis
Based on the perceived symptoms, a doctor can make an estimate that reason about whether the symptoms that hinted of a heart attack or not. Her suspicions are probably reinforced by the appearance of the sufferer, the sound level of blood pressure and heart rate. The doctor will probably be sending it to the examination of ECG and blood tests, but if you still feel the pain, your doctor will probably give penghilangrasa a shot of pain before the examination. This is because pain is scary can bring to the brink of a deeper, which can cause symptoms of heart failure. Pain can also cause long-term psychological impact. The first ECG may not show signs of heart attack and possible examination must be repeated. Sometimes the second test still showed no change, and for this, the diagnosis will depend on an examination of blood. Heart, like all other body cells, containing special chemicals called enzymes. When heart cells undergo damage, the enzymes released in circulation with the blood flow. After a heart attack, the enzyme portion of the level goes up, but instantly next to these enzymes break down fast and therefore not detected again after a day or two days; There are new enzymes that are released a few hours or a few days and then remain in the blood for a few days or even a few weeks.
