Myocardial infarction definition (MI): This is commonly known as a heart attack and occurs when blood vessels that supply blood to the heart are blocked, causing some cells to die. A common cause of this condition is blockage of a coronary artery due to atherosclerosis. Atherosclerosis is a condition in which fatty material (plaque) collects along the walls of the arteries.

Atherosclerosis can lead to myocardial infarction in the following ways:

* Build up of plaque can block a coronary artery restricting oxygen-containing blood from flowing through the blockage.
* The plaque itself can develop cracks or tear causing blood platelets to stick to it forming a blood clot (thrombus). This clot can then block the flow of oxygen-rich blood to the heart.

Blockage of an artery results in ischemia (restricted blood supply). Ischemia and lack of oxygen, if left untreated, can cause death (infarction) of heart muscle tissue (myocardium). Risk factors associated with a heart attack include age, sex, family history, high blood pressure, diabetes, poor diet (containing too much fat), unhealthy cholesterol levels, smoking and chronic kidney disease.

The main symptom of a heart attack is sudden chest pains (usually felt in the left arm or left side of the neck). Other symptoms include shortness of breath, anxiety, nausea, dizziness, palpitations, sweating and fainting. Some people may not suffer any symptom. A heart attack is a medical emergency and anyone suffering from it should seek immediate medical attention as part of acute myocardial infarction management.

Patients potentially suffering from a heart attack may need to go through some exams and tests. Your doctor may perform a physical exam using a stethoscope to check for abnormal sounds. Tests may include coronary angiography, CT scan, echocardiography, electrocardiogram (ECG), MRI and nuclear ventriculography. Blood tests may include Troponin I and troponin T, CPK and CPK-MB and Serum myoglobin.

If you suffer from irregular heartbeats (arrhythmias), immediate treatment may include medication such as aspirin or electrical cardioverson/defibrillation. You may also be given oxygen even if your blood oxygen levels are normal. Medication and fluids may be administered through an intravenous line. A tube may also be inserted into your bladder to determine more symptoms. Additional myocardial infarction treatment includes:

* Angioplasty and stent placement – Angioplasty, also known as percutaneous coronary intervention (PCI), is a therapeutic procedure used for opening arteries for some types of heart attacks. A coronary artery stent is a small tube that opens up inside a coronary artery (placed after angioplasty) and is used to prevent artery from closing up again.
* Thrombolytic Therapy (Clot-Busting Drugs) – This involves the use of drugs to break up the clot. Blood thinners may later be given by month to prevent clot formation later on.

Certain medications for treatment of this condition include Nitroglycerin, antiplatelet medicines, beta blockers, ACE inhibitors and lipid lowering medications. You should also take steps to prevent a heart attack. This includes keeping your blood pressure, blood sugar and cholesterol under control. Lifestyle changes should include a well-balanced diet and regular excercise. Familiarity of myocardial infarction definition and associated risk factors can help you avoid this condition.

Ischemia heart disease is most often known as coronary artery disease and is the leading cause of death in the United States. Ischemia definition refers to a condition in which narrowed arterial walls limit the amount of blood and oxygen that reach the heart. These arteries are narrowed by a buildup of cholesterol plaque. When oxygen is unable to be delivered to the heart, the supply of new blood is effected, triggering a lack of oxygen in the brain and kidneys, resulting in damaged tissue and organ failure. Many people suffer from the malady without even knowing what is ischemia. The term silent ischemia is also used as many sufferers feel no pain and can have heart attacks without any notice. The greatest risk groups are those that have diabetes or have previously had heart attacks.

While the exact cause of what is ischemia has not been determined, several risk factors exist that increase the likelihood of having the disease including smoking, hypertension, type A personality, atherosclerosis, poor nutrition, obesity, elevated cholesterol, high-fat diet, or a family history of ischemia. Many of these risk factors are behavioral and being as such, proactive prevention is the best way of dealing with the condition.

The earliest stages of ischemia definition may have no symptoms. The lack of noticeable warning signs is why the disease is so dangerous and why it is classified as an acute heart condition. In the later stages ischemia symptoms may be present in the form of angina, with a burning, heaviness, or tightness in the chest that can spread to the neck, jaw, shoulder blade, and left arm. These ischemia symptoms become more noticeable in colder weather and can also be triggered by emotional stress or moving from a hot area to a cold area abruptly.

The best way to treat ischemia is by prevention. People who have a number of risk factors should take care to be tested for ischemia. Preventative measures that are commonly used by patients who anticipate potential ischemia complications are to cease smoking, maintain ideal body weight, lower emotional stress, and treat high blood pressure and cholesterol levels. Drugs also exist in four types to combat the possible complications of the condition: beta-blockers, nitrates, calcium channel antagonists, and anti-platelet drugs. Beta-blockers lower the idle heart rate, thus also lowering the levels of oxygen needed by the heart.

Nitrates work by dilating the blood vessels and angina a\sufferers should always keep a ready supply on hand. Calcium channel antagonists work similar to beta-blockers in that they also reduce the normal heart rate. In fact, some tachycardia patients use a combination of the drugs to prevent a rapid heart rate. Anti-platelet drugs such as aspirin work by binding to platelets, thus inhibiting clots from forming on the arterial walls. For those patients who have already had complications it may be necessary to have balloon angioplasty or bypass surgery for coronary arteries. If nothing else has succeeded and the patient’s life is endangered, then a heart transplant may be done to cure ischemia heart disease.

Researches in the field of medical science have invented various therapies and treatments for heart failure treatment. Heart failure has become quite a common problem nowadays. Thus researchers have found out several ways to check heart failures identifying its early symptoms. Heart failure can happen to people of different ages. This can even happen to young children who already are born with heart defects. Nevertheless, heart diseases and its consequences happen mostly to elderly people. Elderly people are quite prone to having lung or respiratory disorders that affect the valves and muscles of the heart. It may also happen that due to natural changes in the aging body, the pumping function of the heart slows down causing congestion and blockage.

Congestive heart failure is caused by the congestion in the lung. Its causes are quite typical among the aged. The ratio of heart diseases among the elderly people is 1 out of every 100 people. Nevertheless heart diseases are rapidly growing among people because of certain unhealthy habits like smoking, drinking, diet with high fat content and high blood pressure.

Heart failure symptoms are caused because a fluid like substance fills up the lung area. The symptoms can be identified when the patient feels fatigued or breathless after doing some routine work like walking or climbing stairs. The fluid weakens the heart slowly and thus the symptoms become worse. The patient might feel more fatigued or breathless even without doing any work. The fluid filling in the heart not only cause fatigue and breathlessness, but also causes frequent urination, weight gain and cough which worsen at night. Fluid filled lungs can cause acute pulmonary edema which causes this nocturnal cough. If the patient is severely suffering from the acute pulmonary edema then he requires immediate treatment.

There can be various heart failure symptoms but some of the typical and most common symptoms include:
• Breathless or shortness of breath,
• Tiredness or fatigue and
• Swelling in certain parts of the body like legs, ankles, abdomen, feet and even veins in the neck.

Not every heart failure patient suffers from the same symptoms. A patient who had a left heart failure can suffer from breathlessness, nocturnal cough or excessive sweating. However a patient with a right heart failure will normally have abnormal heart rhythm and dullness. Thus the failure of the heart can be of two types, systolic and diastolic. The symptoms can be diagnosed through some tests like echocardiogram, chest X-ray and some others. Proper diagnosis helps in early diagnosis of the disease.

It is important for us to know that heart failure does not mean that the heart has stopped functionally completely, but the heart is unable to keep up with work that it requires to pump blood and distribute to all parts of the body. But it cannot be explained easily. Heart failure is quite complex and it has got various aspects, factors, causes and consequences. Hence immediate support and proper heart failure treatment can help the patient to reverse his condition to normal.

The term acute coronary syndromes refers to heart-related conditions that have a similar set of symptoms. This syndrome is most commonly manifested in two conditions: unstable angina and heart attacks. For both of these conditions, the present symptoms can include chest pain, nausea, sweating, vomiting, dizziness, or pain in the neck, back, stomach, jaw, or arms. For a number of patients the chest pain can be felt in widely different ways, from a slight tingling to palpitations to sever constriction or throbbing pain. If a patient experiences any of these symptoms, emergency medical services must be contacted immediately.

The first condition, unstable angina or intermediate coronary syndrome, is a chest pain that originates from an inability of blood to flow unimpeded. Many patients experience stable angina, which is the same type of pain, but it occurs only in certain situations such as after physical exertion. However, unstable angina may strike at any time, even while a patient is at rest. This unpredictability and lack of fixed duration can be both dangerous and frightening to a patient. Although it is painful, the heart is not damaged in this condition. Additionally, unstable angina is a precursor that the patient is at risk for having a heart attack.

The second condition, a heart attack, happens when the impeded blood flow causes damage to the heart. The inability of the body to get fresh oxygen and blood to the heart can cause the heart to stop functioning. For this reason heart attacks are an acute heart condition and can be potentially fatal. Treatment of a heart attack can sometimes be completely resolved with medication use such as aspirin or thrombolytic drugs. In other cases, angioplasty may be required to allow normal blood flow to resume. Angioplasty is the use of a catheter to inflate a balloon in the blocked passageway. In the most extreme situations, heart surgery must be done to prevent a fatality.

Both of these conditions can be diagnosed with the use of an electrocardiogram. In addition, this apparatus can inform a patient which condition was experienced. Another test that can be done is a cardiac perfusion scan. This test evaluates the amount of blood being returned to the heart.

Acute coronary syndrome guidelines state that any patients who is in a high risk group for heart complications can be proactive by making behavior modifications that will prevent or lower the likelihood of having unstable angina or heart attacks and aid in the management of acute coronary syndrome. One modification is by changing the diet. A healthy diet for high risk patients will include plenty of fruits, vegetables, whole grains, and lean protein. Also, at least a minimum of exercise should be done every week. In the patient smokes cigarettes, the best thing that can be done to improve the health is to quit smoking. In addition, close monitoring of cholesterol and blood pressure levels can inform a patient when these levels are outside of acceptable levels. These steps, along with regular visits to a local physician, will aid a patient in coping with acute coronary syndromes.

A patient experiencing chest pains can be one of the most difficult types of problems for a doctor to treat. These pains can be classified as anything from a simple tightening of the torso area that causes pressure irritation to crushing and pronounced pain that debilitates the victim. Because of the potential severity of the underlying causes, chest pain is considered an acute heart condition.

The symptoms arising from chest pain can be varied and contingent upon which complication is causing the pain. Common symptoms other than the actual pain located in the chest include sweating, vomiting, painful swallowing, nausea, abnormal salivation, abdominal pain, coughing, heartburn, a rise in heart rate, dizziness or fatigue.

As there can be many causes of chest pain, physicians must be familiar with potentially fatal sources as well as those that are reasonably safe. Perhaps the most dangerous cause is a heart attack. These happen when the heart’s blood flow is reduced or stopped, most commonly resulting from a clogged or blocked artery leading to the heart. In the chest sharp pain may be identified as a heart attack by the pain spreading to the left arm and shoulder, neck or jaw. If these symptoms are noticed, emergency medical attention is needed as soon as possible. Some other life-threatening agents of chest pain include angina, pulmonary embolisms, a perforated viscus, aortic dissection, collapsed lungs, or pain resulting from cocaine use. Some less serious causes of chest pain may be due to pneumonia, esophageal disorders, pericarditis, herpes zoster, costochondritis, or mitral valve prolapse.

For patients who are in high-risk categories for heart attacks and other pulmonary issues, some steps may be taken to reduce the chances of incurring chest pain. Simple exercise improves pulmonary health and has many added benefits as well. In addition, being conscious of fat and cholesterol intake can diminish the likelihood of suffering from a heart attack. Regular monitoring of a patient’s health can be achieved with routine visits with a local physician.

Treatment of pain in chest areas depends entirely on what condition has been diagnosed as the root cause of the pain. In the case of a heart attack, some medications such as aspirin or thrombolytic drugs may be used to resolve the issue. In worse cases, a patient may need angioplasty, a procedure that uses a thin catheter to inflate a balloon inside the blocked artery, thus allowing the flow of blood to resume. In severe situations, surgery may be needed to correct the problem. If the cause of the chest pain is unknown, a physician should be sought to discover the root source before any treatment is administered. Chest pains can be difficult to cope with, but knowledge of the reasons behind the irritation can be helpful to patients who experience this problem.

A cardiac arrest definition is similar to that of sudden cardiac deaths. However, cardiac arrest can be defined as the abrupt cessation or termination of the normal circulation of blood because of the heart failure. This happens because the heart fails to contract effectively during the systole. Cardiac arrest can also be termed as circulatory arrest or cardiopulmonary arrest. It is important to know that a cardiac arrest is different and severe than a heart attack, but at times heart attack or myocardial infraction can cause cardiac arrest.

It has been seen that in adults ischemic heart disease plays an important part in causing cardiac arrest. If an autopsy is done, 30% of the patient would show signs of myocardial infraction. Some of the other causes of cardiac arrest are arrhythmias, structural abnormalities and cardiomyopathies. There are some non cardiac causes too that includes trauma, cancer, infections and overdoses.

Cardiac arrest cause death, hence one must know the exact symptoms of this danger if it is not attended immediately. Just before a cardiac arrest the patient may show some signs or symptoms that will help others to identify the arrest. These cardiac arrest symptoms are:

• Feeling Sick
• Feeling dizzy
• Finding it difficult to breathe normally
• Getting chest pain

A cardiac arrest prevents or blocks blood circulation preventing the delivery of oxygen in all parts of the body and especially brain. This lack of oxygen in brain or as it is called cerebral hypoxia causes the patient to lose his consciousness and he finds it extremely difficult to breathe normally, although he may continue with agonal breathing. Thanks to the researchers of modern medical science, cardiac arrest treatment now is able to help the patient regain his normal breathing and lead a normal life. However, it has to be remembered that if a patient remains untreated for more than five minutes, his brain is likely to be affected severely. But now a new treatment called induced hypothermia can extend this time and prevent brain damage. Nevertheless immediate action must be taken in order to save the patient and recover his neurological health.

Cardiac arrest should always be dealt with emergency. If the patient gets immediate treatment his condition can reverse to normal but an unexpected cardiac arrest can also lead to death. Hence it is called sudden cardiac death. Sudden cardiac arrest causes are numerous and it is also synonymous to clinical death. Cardiopulmonary resuscitation is the first aid treatment for any cardiac arrest patient. This treatment provides temporary circulatory support until a proper medical treatment is available. The circulatory support may vary depending on the rhythm of the heart. It may also require defibrillation.

When a patient gets a cardiac arrest he can fall down on the ground if he is standing. This fall can be as fatal. But an immediate support can ensure that no more damage is done to him. However, a cardiac arrest definition can give us an idea about the severity of this problem which will lead us to know the proper way to deal with it.

Atrial fibrillation heart disease is one of the most common types of cardiac arrhythmia that is encountered in the medical science. In the United States of America atrial fibrillation is quite a significant problem. This problem is generally seen within the age group of 50 to 59 years. Previously this cardiac disease was present in ratio of 0.5% but it increased up to 9% in the 1980s and also carried a high mortality risk.

The most common symptoms of atrial fibrillation are palpitations, breathlessness, dizziness, chest discomfort and even stroke. In some cases atrial fibrillation is asymptomatic and identified as coincidental finding while diagnosing other problem. The treatment for atrial fibrillation should be done prompt and properly otherwise there is always a risk of brain and heart damages, however, immediate treatment enables a patient to prevent these damages.

Recent studies have shown that more than two million Americans get affected by atrial fibrillation. It accounts to almost 5% of the whole population of the United States. The study also says that most of these affected people are over 69 years of age. The disease develops and increases with age and is related with other cardiovascular symptoms like coronary artery, hypertension, heart failure, diabetes mellitus and valvular heart diseases.
The causes and symptoms of atrial fibrillation can vary from one patient to another. But while the patient gets affected by this unique heart disease the upper two chambers of his heart or the atria starts to beat irregularly and chaotically. It does not match the rhythm of the two other chambers and thus the atria becomes out of coordination with the ventricles or the lower chambers of the heart. Thus atrial fibrillation can be defined as rapid or irregular heart beat rate that causes the heart to pump poor blood flow to the other organs of the body. The most common symptoms of this cardiac disease are breathlessness, palpitations, weakness and dullness.

It has been observed that atrial fibrillation can also be the cause of stroke and fatigue. The stroke and fatigue happens when the heart does not function properly and as a result the patient suffers from high blood pressure apart from other heart diseases.Atrial fibrillation treatment is quite complex and it is done following different ways depending on the condition of the patient. These treatments are:

• Anticoagulation
• Heart Rate control
• Rhythm control
• Antiarrhythmic medicines
• Ablation
• Surgery
• Device implants

Primarily the treatment is done to prevent blood from clotting reducing the risk of stroke. The treatment is also designed to control the heart rate and observe the number of times the ventricles contract in a minute. Disease like atrial fibrillation can be cured with proper diagnosis and treatment. Thus medical science has taken steps ahead and invented the latest treatments and therapies to limit the risk factors of atrial fibrillation. There are useful atrial fibrillation guidelines that medical practitioners can follow to treat a patient with atrial fibrillation heart disease.
