What are myocardial perfusion defects?
Fourth, myocardial perfusion defects (F2, F3)—regions in the LV myocardium in which blood flow has been obstructed—are detected qualitatively and semiquantitatively. Perfusion defects are apparent qualitatively as gray-black blotches pervading the LV myocardium (F2, F3).
What causes myocardial dysfunction?
Conditions that can cause myocardial ischemia include: Coronary artery disease (atherosclerosis). Plaques made up mostly of cholesterol build up on your artery walls and restrict blood flow. Atherosclerosis is the most common cause of myocardial ischemia.
What is a myocardial test?
Myocardial perfusion is an imaging test. It’s also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping. For example, after a heart attack, it may be done to find areas of damaged heart muscle.
What is fixed myocardial perfusion defect?
A fixed defect is a perfusion defect present at stress and rest. Primary differential for a fixed defect includes scarring from infarction, chronically ischemic areas called hibernating myocardium, or attenuation.
What’s considered a heart defect?
A heart defect is a problem in the heart’s structure. Kids who have a heart defect were born with it. Heart defects are often called “congenital,” which means “present at birth.” Heart defects are also sometimes referred to as “congenital heart disease.” Heart defects can range from mild to severe.
What tests confirm myocardial damage?
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 the most common heart defect?
The most common type of heart defect is a ventricular septal defect (VSD).
How is myocardial disease diagnosed?
In an MRI, large magnets and radio waves create images of the inside of your body. During a heart MRI, a technician creates images of your blood vessels and heart while it’s beating. After the test, your doctor can use the images to diagnose many conditions, such as heart muscle diseases and coronary artery disease.
Is myocardial damage reversible?
Myocardial stunning occurs when myocytes injury is reversible and the cells have no structural damage; it can last for various periods of time after the restoration of normal blood flow.
What are the 5 risks for heart disease?
Major Risk Factors
- High Blood Pressure (Hypertension). High blood pressure increases your risk of heart disease, heart attack, and stroke.
- High Blood Cholesterol. One of the major risk factors for heart disease is high blood cholesterol.
- Diabetes.
- Obesity and Overweight.
- Smoking.
- Physical Inactivity.
- Gender.
- Heredity.
What is the most common cardiac defect?
How serious is myocardial injury?
Myocardial injury is a concerning prognosis; the 5-year mortality rate is approximately 70%, with a major adverse cardiovascular event rate of 30% in the same period. The differential diagnosis is broad and can be divided into acute and chronic precipitants. The initial workup involves an assessment for myocardial ischemia .
What are the 5 types of myocardial infarction?
Types of Myocardial Infarction. Type 2: Ischemic myocardial necrosis due to supply-demand mismatch, e.g. coronary spasm, embolism, low or high blood pressures, anemia, or arrhythmias . Type 4: Procedure related, post PCI or stent thrombosis ( cTr > 5X Decision Level). Type 5: Post CABG (cTr > 10X Decision Level).
What does myocardial degeneration mean?
MYOCARDIAL DEGENERATION. ☆. As its name implies, the essential factor is degenerative change in the heart muscle, and, since tissue degeneration is invariably associated with reduced functional effi- ciency, depression of myocardial function will be the inevitable outcome of the degenerative process.
What condition can myocardial ischemia lead to?
Myocardial ischemia can lead to serious complications, including: Heart attack. If a coronary artery becomes completely blocked, the lack of blood and oxygen can lead to a heart attack that destroys part of the heart muscle. The damage can be serious and sometimes fatal.
