What is the difference between mi and angina
Angina pectoris is a syndrome, and myocardial infarction is a fatal condition which can lead to the abrupt death of a person. Myocardial infarction and angina pectoris are two significantly serious disorders and are frequently interchanged. Early identification of angina pectoris may avert the disorder from progressing into myocardial infarction. This write-up aims to directly indicate the differences among the two and give the necessary interventions to manage them.
Angina pectoris can be medically termed as chest pain, an outcome of ischemia, or the reduction in the blood supply to the myocardium of the heart from the coronary arteries. The insufficiency of blood supply is due to the inadequacy of oxygen that reaches the heart. The pain in the chest is linked to angina pectoris as described by the patient as a pressing, squeezing, choking, bursting, or burning sensation felt at the sternum.
Pain may be abrupt and recurrent, frequently resulting from physical exertion, and is relieved by nitroglycerin and rest. The predisposing factor that attack depends on is the type of angina the person has because they vary on their precipitating factors. On the other hand, myocardial infarction is a medical emergency more commonly called a heart attack. It is an outcome of the destruction or death of myocardial cells that is due to the insufficiency of oxygen. The pain in this condition is expressed to be excruciating or crushing and typically spreads from the heart to the shoulders, jaw, neck, and back.
The chest pain and other associated symptoms are not relieved by nitroglycerin or rest. Both disorders can be confirmed using an electrocardiogram or ECG.
Electrocardiogram test results of the patient with symptoms of angina pectoris illustrate an ST-segment depression. The most dangerous time for someone who is having a heart attack is during the first few hours and before they go to a hospital. During this period, up to 20 to 30 percent of people with a heart attack may die, so it is critical to seek medical attention immediately when people suspect they are having a heart attack.
Most deaths occur in the first 3 or 4 months, typically in people who continue to have angina, abnormal heart rhythms Overview of Abnormal Heart Rhythms Abnormal heart rhythms arrhythmias are sequences of heartbeats that are irregular, too fast, too slow, or conducted via an abnormal electrical pathway through the heart. The prognosis is worse if the heart has enlarged after a heart attack than if heart size remains normal.
Older people are more likely to die after a heart attack and to have complications, such as heart failure. The prognosis for smaller people is worse than that for larger people. This finding may help explain why the prognosis for women who have had a heart attack is, on average, worse than that for men.
Women also tend to be older and to have more serious disorders when they have a heart attack. Also, they tend to wait longer after a heart attack to go to the hospital than do men. For people who have had a heart attack, doctors recommend taking one baby aspirin , one half of an adult aspirin , or one full adult aspirin daily.
People with an allergy to aspirin may take clopidogrel instead. For people who have not had a heart attack but who are over 50 years of age and have 2 or more risk factors Risk Factors Coronary artery disease is a condition in which the blood supply to the heart muscle is partially or completely blocked. However, aspirin can sometimes cause complications such as gastrointestinal bleeding Gastrointestinal Bleeding Bleeding may occur anywhere along the digestive gastrointestinal [GI] tract, from the mouth to the anus.
Blood may be easily seen by the naked eye overt , or blood may be present in amounts Doctors help people weigh their individual risk and benefit. The more serious the heart attack, the more benefit beta-blockers provide. However, some people cannot tolerate the side effects such as wheezing, tiredness, erectile dysfunction Erectile Dysfunction ED Erectile dysfunction ED is the inability to attain or sustain an erection satisfactory for sexual intercourse.

Angiotensin-converting enzyme ACE inhibitors, such as captopril , enalapril , perindopril, trandolapril , lisinopril , and ramipril , are often prescribed after a heart attack. These drugs help prevent death and the development of heart failure, particularly in people who have had a massive heart attack or who develop heart failure.
People should also make changes in their lifestyle. They should eat a low-fat diet and increase the amount of exercise they get. People who have high blood pressure or diabetes should try to keep those disorders under control. People who smoke should quit.
Acute coronary syndromes are medical emergencies. Half of deaths due to a heart attack occur in the first 3 or 4 hours after symptoms begin. The sooner treatment begins, the better the chances of survival. Anyone having symptoms that might indicate an acute coronary syndrome should obtain prompt medical attention. People who may be having a heart attack are usually admitted to a hospital that has a cardiac care unit.
Heart rhythm, blood pressure, and the amount of oxygen in the blood are closely monitored so that heart damage can be assessed. Nurses in these units are specially trained to care for people with heart problems and to handle heart emergencies. Often, oxygen is given through nasal prongs or a face mask. Providing more oxygen to the heart helps keep heart tissue damage to a minimum. If no complications Complications of an Acute Coronary Syndrome The heart muscle needs a constant supply of oxygen-rich blood.
If complications such as abnormal heart rhythms Overview of Abnormal Heart Rhythms Abnormal heart rhythms arrhythmias are sequences of heartbeats that are irregular, too fast, too slow, or conducted via an abnormal electrical pathway through the heart. The most important issue in the early part of treatment of a heart attack is to get to medical attention quickly so doctors can attempt to restore blood flow in the affected artery.
People who think they may be having a heart attack should chew an aspirin tablet immediately after calling an ambulance. If aspirin is not taken at home or given by emergency personnel, it is immediately given at the hospital. This therapy improves the chances of survival by reducing the size of the clot if present in the coronary artery.
People with an allergy to aspirin may be given clopidogrel , ticlopidine , or ticagrelor instead. People are given drugs to prevent the formation of blood clots, to reduce anxiety, and to reduce the size of the heart. People may need to take these drugs for some time after they have recovered from a heart attack. Drugs are used to reduce the heart's workload during and after a heart attack. Slowing the rate enables the heart to work less hard and reduces the area of damaged tissue.
Most people are also given an anticoagulant drug, such as heparin , to help prevent the formation of additional blood clots. Most people are given nitroglycerin , which relieves pain by reducing the workload of the heart and possibly by dilating arteries. Usually, it is first given under the tongue, then intravenously. Occasionally, when nitroglycerine cannot be used or is ineffective, doctors give morphine to reduce discomfort and anxiety. Angiotensin-converting enzyme ACE inhibitors Angiotensin-converting enzyme inhibitors High blood pressure is very common.
It often does not cause symptoms; however, high blood pressure can increase the risk of stroke, heart attacks, and heart failure. Therefore, it is important Therefore, these drugs are usually given in the first few days after a heart attack and prescribed indefinitely.
Statins Treatment Dyslipidemia is a high level of lipids cholesterol, triglycerides, or both or a low high-density lipoprotein HDL cholesterol level. Second, we defined the features that seemed to be effective in recognizing coronary artery disease.
The features are extracted from the region between the end-diastolic endocardial contour and end-systolic endocardial contour in two CK images: one obtained when the subject was at rest and the other after exercise. Nine features were considered effective for differentiating old myocardial infarction and angina pectoris, and the effectiveness in recognizing coronary artery disease, which includes old myocardial infarction and angina pectoris, was evaluated.
Or if physical exertion is a trigger for you, you can make sure you take your GTN spray with you when you are planning to do some exercise. Stable angina is when you get angina symptoms during moderate physical activity or when you are pushing yourself physically. Unstable angina is when you get angina symptoms while doing very little or resting. This can happen to people who have never experienced angina before. If your angina becomes more frequent, severe, lasts longer or happens when you are doing very little or resting, see your doctor in the next 24 hours.
You may need further tests or treatment. The coronary arteries supply blood to your heart muscle by routing it through a network of smaller blood vessels. When a blood flow problem occurs in one or more of the smaller blood vessels supplying blood to your heart, it is called microvascular angina, cardiac syndrome X, or coronary microvascular dysfunction. Because of the reduced size of the blood vessels, it's likely you will be advised to start a combination of medication and lifestyle changes rather than offered a stent or heart bypass surgery.
Women seem to be more likely than men to experience microvascular angina. The reasons for this have not yet been confirmed. Angina is a symptom of coronary artery disease or atherosclerosis. This is a process that is accelerated by a number of factors including unhealthy lifestyle choices such as smoking, poor diet, being overweight, physical inactivity and poor mental health and wellbeing.
Making changes to your risk factors can slow or stop the damage to your arteries and lower your risk of having another heart attack. Browse angina stories.
