What are the differential diagnosis of myocardial infarction

Cardiovascular: stable angina, another form of ACS (unstable angina or NSTEMI), acute pericarditis, myocarditis, aortic stenosis, aortic dissection, pulmonary embolism. Respiratory: pneumonia, pneumothorax.

What are the diagnosis for myocardial infarction?

Acute myocardial infarction is myocardial necrosis resulting from acute obstruction of a coronary artery. Symptoms include chest discomfort with or without dyspnea, nausea, and diaphoresis. Diagnosis is by ECG and the presence or absence of serologic markers.

What is the differential diagnosis of angina pectoris?

Differential diagnosis Other conditions can mimic stable angina; these include acute myocardial infarction, unstable angina, acute pericarditis, acute pulmonary embolism, and pneumonia, to name a few.

What are the 5 types of myocardial infarction?

ST segment elevation myocardial infarction (STEMI) non-ST segment elevation myocardial infarction (NSTEMI) coronary spasm, or unstable angina.

What are the diagnostic tests that would be done to confirm the MI?

Tests available include: Cardiac Troponin I or Troponin T – which are both very sensitive and specific and are the recommended laboratory tests for the diagnosis of MI. Serial testing is recommended in order to confirm or exclude a rise or fall in troponin concentration.

What is a Type 3 myocardial infarction?

The type 3 myocardial infarction was defined according to the Universal definition of myocardial infarction, that is, cardiac death with symptoms suggestive of myocardial ischemia and presumed new ischemic ECG changes or new left bundle branch block, but death occurring before blood samples could be obtained, before

What are the main causes of myocardial infarction?

A heart attack occurs when one of the heart’s coronary arteries is blocked suddenly or has extremely slow blood flow. A heart attack also is called a myocardial infarction. The usual cause of sudden blockage in a coronary artery is the formation of a blood clot (thrombus).

What is the most common type of myocardial infarction?

Type 2 MI is the most common type of MI encountered in clinical settings in which is there is demand-supply mismatch resulting in myocardial ischemia. This demand supply mismatch can be due to multiple reasons including but not limited to presence of a fixed stable coronary obstruction, tachycardia, hypoxia or stress.

What is type1 and type2 mi?

Type 1 MI is a primary coronary arterial event attributable to atherothrombotic plaque rupture or erosion. Type 2 MI occurs secondary to an acute imbalance in myocardial oxygen supply and demand without atherothrombosis.

What is the difference between angina and myocardial infarction?

The key difference between angina and a heart attack is that angina is the result of narrowed (rather than blocked) coronary arteries. This is why, unlike a heart attack, angina does not cause permanent heart damage.

What are the benefits of considering a differential diagnosis?

  • narrow down the working diagnosis.
  • guide medical evaluation and treatment.
  • rule out life threatening or time critical conditions.
  • enable the doctor to make the correct diagnosis.

How is stable angina diagnosed?

  1. Blood tests.
  2. Electrocardiogram (EKG).
  3. Stress test (regular stress test, nuclear stress test or stress echocardiogram test).
  4. Coronary angiography.
  5. CT (Computed Tomography) scan.

What blood tests are done to confirm heart Mi?

Measuring troponin T using a high-sensitivity troponin T test helps doctors diagnose a heart attack and determine your risk of heart disease. An increased level of troponin T has been linked with a higher risk of heart disease in people who have no symptoms.

What are the 3 cardiac enzymes?

Cardiac enzymes ― also known as cardiac biomarkers ― include myoglobin, troponin and creatine kinase.

What cardiac biomarkers are used to diagnose myocardial infarction?

Two well known biomarkers in use for diagnosis of acute myocardial infarction are Creatine-Kinase-MB isoform and Cardiac Troponin. In 2000, Cardiac Troponin replaced CK-MB as the biomarker of choice for diagnosing a myocardial infarction [6].

How is arrhythmias diagnosed?

The most common test used to diagnose an arrhythmia is an electrocardiogram (EKG or ECG). Your doctor will run other tests as needed. She or he may recommend medicines, placement of a device that can correct an irregular heartbeat, or surgery to repair nerves that are overstimulating the heart.

What is myocardial infarction?

Overview. A heart attack (myocardial infarction) happens when one or more areas of the heart muscle don’t get enough oxygen. This happens when blood flow to the heart muscle is blocked.

What is a Type 1 myocardial infarction?

Type 1 MI is due to acute coronary atherothrombotic myocardial injury with either plaque rupture or erosion and, often, associated thrombosis. Most patients with ST-segment elevation MI (STEMI) and many with non-ST-segment elevation MI (NSTEMI) fit into this category.

What are the stages of myocardial infarction?

The myocardial infarction process can be divided into 2 phases, an early evolving phase (the first 6 hours) and a later convalescent phase. An evolving infarction is associated with an occluded coronary artery; in most cases, a thrombotic occlusion occurs.

What is a Type 1 Nstemi?

• Type I NSTEMI is due to unstable CAD with. atherosclerotic plaque disruption resulting in a. coronary thrombus & subsequent ischemia.

What is inferior MI?

An inferior wall MI — also known as IWMI, or inferior MI, or inferior ST segment elevation MI, or inferior STEMI — occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel.

How is Nstemi diagnosed on ECG?

  1. depressed ST wave or T-wave inversion.
  2. no progression to Q wave.
  3. partial blockage of the coronary artery.

Why ST elevation occurs in myocardial infarction?

ST segment elevation occurs because when the ventricle is at rest and therefore repolarized, the depolarized ischemic region generates electrical currents that are traveling away from the recording electrode; therefore, the baseline voltage prior to the QRS complex is depressed (red line before R wave).

What is a differential diagnosis example?

For example, many infections cause fever, headaches, and fatigue. Many mental health disorders cause sadness, anxiety, and sleep problems. A differential diagnosis looks at the possible disorders that could be causing your symptoms.

What are the different types of diagnosis?

  • Biopsy. A biopsy helps a doctor diagnose a medical condition. …
  • Colonoscopy. …
  • CT scan. …
  • CT scans and radiation exposure in children and young people. …
  • Electrocardiogram (ECG) …
  • Electroencephalogram (EEG) …
  • Gastroscopy. …
  • Eye tests.

What is the difference between diagnosis and differential diagnosis?

A differential diagnosis means that there is more than one possibility for your diagnosis. Your doctor must differentiate between these to determine the actual diagnosis and appropriate treatment plan. Unfortunately, there are currently no lab tests to identify depression.

What does a EKG show?

An electrocardiogram (ECG or EKG) records the electrical signal from your heart to check for different heart conditions. Electrodes are placed on your chest to record your heart’s electrical signals, which cause your heart to beat. The signals are shown as waves on an attached computer monitor or printer.

What is the management of myocardial infarction?

Although the immediate priority in managing acute myocardial infarction is thrombolysis and reperfusion of the myocardium, a variety of other drug therapies such as heparin, β-adrenoceptor blockers, magnesium and insulin might also be considered in the early hours.

What is trimetazidine 35mg?

Trimetazidine is an anti-ischemic metabolic modulator [120], with similar anti-anginal efficacy to propranolol in doses of 20mg thrice daily. From: Coronary Artery Disease, 2018.

How is troponin test done?

What happens during a troponin test? A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out.

What is Lipid profile test used for?

A complete cholesterol test is also called a lipid panel or lipid profile. Your doctor can use it to measure the amount of “good” and “bad” cholesterol and triglycerides, a type of fat, in your blood. Cholesterol is a soft, waxy fat that your body needs to function properly.
