Heart attack treatment
Coronary arteries can go into spasm and cause angina without a specific cause, this is known as Prinzmetal angina. There can be ekg changes associated with this situation, and the diagnosis is made by heart catheterization showing normal coronary arteries that go into spasm when challenged with a medication injected in the cath lab. Approximately 2 to 3 of patients with heart disease have coronary artery vasospasm. In their normal position, the coronary arteries lie on the surface of the heart. On occasion, in the course of a part, the artery can dive into the heart muscle itself. When the heart muscle contracts, it can temporarily kink the artery and cause angina. Again, diagnosis is made by heart catheterization.
Picture of heart Attack (Myocardial Infarction). Heart Attack risk factors, a heart attack is most often caused by narrowing of the arteries by cholesterol plaque and their subsequent rupture. This is known as atherosclerotic heart disease (ahsd) or coronary artery disease (CAD). The risk factors schurft for ahsd are the same as those for stroke (cerebrovascular disease) or peripheral vascular disease. These risk factors include: While heredity is beyond a person's control, all the other risk factors can be minimized to try to prevent coronary artery disease from developing. If atherosclerosis (atheromafatty plaque sclerosishardening) is already present, minimizing these risk factors can decrease further narrowing. Non-coronary artery disease causes a heart attack may also occur. Examples include: Cocaine use. This drug can cause the coronary arteries to go into enough caillot spasm to cause a heart attack. Because of the irritant effect on the heart's electrical system, cocaine can also cause fatal heart rhythms. Prinzmetal angina or coronary artery vasospasm.
Block the oxygen supply completely, and the muscle starts to die. Heart muscle gets its blood supply from arteries that originate in the aorta just as it leaves the heart. The coronary arteries run along the surface of the heart and supply oxygen-rich blood to the heart muscle. The right coronary artery supplies the right ventricle of the heart and the inferior (lower) portion of the left ventricle. The left anterior descending coronary artery supplies the majority of the left ventricle, while the circumflex artery supplies the back of the left ventricle. The ventricles are the lower chambers of the heart; the right ventricle pumps blood to the lungs and left pumps it to the rest of the body. What, causes a heart Attack? Over time, plaque can build up along the course of an plekken artery and narrow the channel through which blood flows. Plaque is made up of cholesterol buildup and eventually may calcify or harden, with calcium deposits. If the artery becomes too narrow, it cannot supply enough blood to the heart muscle when it becomes stressed.

If you believe that you are having the symptoms of a heart attack, please call 911 immediately and seek medical attention. The heart is a muscle like any other in the body. Arteries supply it with oxygen-rich blood so that it can contract and push blood to the rest of the body. When there isn't enough oxygen flow to a muscle, its function begins to suffer.

22 "Silent" myocardial infarctions can happen without any symptoms at all. 11 These cases can be discovered later on electrocardiograms, using blood enzyme tests, or at autopsy after a person has died. Such silent myocardial infarctions represent between 22 and 64 of all infarctions, 11 and are more common in the elderly, 11 in those with diabetes mellitus 15 and after heart transplantation. In people with diabetes, differences in pain threshold, autonomic neuropathy, and psychological factors have been cited as possible explanations for the lack of symptoms. 32 In heart transplantation, the donor heart is not fully innervated by the nervous system of the recipient. 33 The most prominent risk factors for myocardial infarction are older age, actively smoking, high blood pressure, diabetes mellitus, and total cholesterol and high-density lipoprotein levels. 18 Many risk factors of myocardial infarction are shared with coronary artery disease, the primary cause of myocardial infarction, 15 with other risk factors including male sex, low levels of physical activity, a past family history, obesity, and alcohol use.
24 The pain most suggestive of an acute mi, with the highest likelihood ratio, is pain radiating to the right arm and shoulder. 25 Similarly, chest pain similar to a previous heart attack is also suggestive. 26 The pain associated with mi is usually diffuse, does not change with position, and lasts for more hoofdpijn than 20 minutes. 22 levine's sign, in which a person localizes the chest pain by clenching one or both fists over their sternum, has classically been thought to be predictive of cardiac chest pain, although a prospective observational study showed it had a poor positive predictive value. 27 pain that responds to nitroglycerin does not indicate the presence or absence of a myocardial infarction. 28 Other symptoms edit Chest pain may be accompanied by sweating, nausea or vomiting, and fainting, 22 25 and these symptoms may also occur without any pain at all. 24 In women, the most common symptoms of myocardial infarction include shortness of breath, weakness, and fatigue.
29 Shortness of breath is a common, and sometimes the only symptom, occurring when damage to the heart limits the output of the left ventricle, with breathlessness arising either from low oxygen in the blood, or pulmonary edema. 24 30 Other less common symptoms include weakness, light-headedness, palpitations, and abnormalities in heart rate or blood pressure. 15 These symptoms are likely induced by a massive surge of catecholamines from the sympathetic nervous system, which occurs in response to pain and, where present, low blood pressure. 31 Loss of consciousness due to inadequate blood flow to the brain and cardiogenic shock, and sudden death, frequently due to the development of ventricular fibrillation, can occur in myocardial infarctions. 23 Cardiac arrest, and atypical symptoms such as palpitations, occur more frequently in women, the elderly, those with diabetes, in people who have just had surgery, and in critically ill patients.

7 Rates of mi for a given age have decreased globally between 1919 In 2011, ami was one of the top five most expensive conditions during inpatient hospitalizations in the us, with a cost of about.5 billion for 612,000 hospital stays. 20 Contents Terminology edit main article: Acute coronary syndrome myocardial infarction (MI) refers to tissue death ( infarction ) of the heart muscle ( myocardium ). It is a type of acute coronary syndrome, which describes a sudden or short-term change in symptoms related to blood flow to the heart. 21 Unlike other causes of acute coronary syndromes, such as unstable angina, a myocardial infarction occurs when there is cell death, as measured by a blood test for biomarkers (the cardiac protein troponin or the cardiac enzyme ck-mb ). 15 When there is evidence of an mi, it may be classified as an st elevation myocardial infarction (stemi) or Non-st elevation myocardial infarction (nstemi) based on the results of an ecg.
22 The phrase "heart attack" is often used non-specifically to refer to a myocardial infarction and to sudden cardiac death. An mi is different from—but can cause— cardiac arrest, where the heart is not contracting at all or so poorly that all vital organs cease to function, thus causing death. It is also distinct from heart failure, in which the pumping action of the heart is impaired. However, an mi may lead to heart failure. 23 Signs and symptoms edit pain edit Chest pain is the most common symptom of acute myocardial infarction and is often described as a sensation of tightness, pressure, or squeezing. Pain radiates most often to the left arm, but may also radiate to the lower jaw, neck, right arm, back, and upper abdomen.

8 In people with blockages of multiple coronary arteries and diabetes, coronary artery bypass surgery (cabg) may be recommended rather than angioplasty. 16 symptomen After an mi, lifestyle modifications, along with long term treatment with aspirin, beta blockers, and statins, are typically recommended. 7 Worldwide, about.9 million myocardial infarctions occurred in 2015. 9 More than 3 million people had cerebral an st elevation mi and more than 4 million had an nstemi. 17 stemis occur about twice as often in men as women. 18 About one million people have an mi each year in the United States. 2 In the developed world the risk of death in those who have had an stemi is about.

12 13 A number of tests are useful to help with diagnosis, including electrocardiograms (ECGs blood tests, and coronary angiography. 6 An ecg, which is a recording of the heart's electrical activity, may confirm an st elevation mi (stemi) if st elevation is present. 7 14 Commonly used blood tests include troponin and less often creatine kinase. 6 Treatment of an mi is time-critical. 15 Aspirin is an appropriate immediate treatment for a suspected. 8 Nitroglycerin or opioids may be used to help with chest pain; however, they do not improve overall outcomes. 7 8 Supplemental oxygen is recommended in those with low oxygen levels or shortness of breath. 8 In a stemi, treatments attempt to restore blood flow to the heart, and include percutaneous coronary intervention (pci where hydrocolloid the arteries are pushed open and may be stented, or thrombolysis, where the blockage is removed using medications. 7 people who have a non-st elevation myocardial infarction (nstemi) are often managed with the blood thinner heparin, with the additional use of pci in those at high risk.
Women more often have atypical symptoms than men. 10, among those over 75 years old, about 5 have had an mi with little or no history of symptoms. 11, an mi may cause heart failure, an irregular heartbeat, cardiogenic shock, or cardiac arrest. 2 3 Most MIs occur due to coronary artery disease. 2 Risk factors include high kloven blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet, and excessive alcohol intake, among others. 4 5 The complete blockage of a coronary artery caused by a rupture of an atherosclerotic plaque is usually the underlying mechanism of. 2 MIs are less commonly caused by coronary artery spasms, which may be due to cocaine, significant emotional stress, and extreme cold, among others.
