What is the meaning of non valvular atrial fibrillation?
Nonvalvular Atrial Fibrillation This is atrial fibrillation that isn’t caused by a problem with a heart valve. It’s caused by other things, such as high blood pressure or an overactive thyroid gland.
What is rheumatic atrial fibrillation?
Atrial fibrillation (AF) is frequent in patients with rheumatic mitral stenosis (MS). Pressure overload leads to marked structural and electrical remodelling of left atrium. The frequency of persistent AF increases with age and paroxysmal, asymptomatic, AF seems even more frequent.
What does Nvaf mean?
The term nonvalvular atrial fibrillation (NVAF) is used with increasing frequency to describe patients who may benefit from new oral anticoagulants (NOACs).
Does AFib shorten your life?
Untreated AFib can raise your risk for problems like a heart attack, stroke, and heart failure, which could shorten your life expectancy.
Why do you get atrial fibrillation in mitral stenosis?
Heart valve stenosis is also linked to a higher risk for atrial fibrillation. For example, mitral valve stenosis results in an obstruction to blood flow from the left atrium to the left ventricle causing the pressure to increase in the left atrium. As a result, the heart enlarges, and atrial fibrillation can occur.
Can rheumatic fever cause atrial fibrillation?
Damage to heart muscle. Damage to the mitral valve, other heart valves or other heart tissues can cause problems with the heart later in life. Resulting conditions can include: An irregular and chaotic heartbeat (atrial fibrillation)
What constitutes valvular AF?
As long as there is no better new term or widely accepted definition, “valvular AF” refers to patients with mitral stenosis or artificial heart valves. Patients with “non-valvular AF” may have other types of valvular heart disease.
What is nonvalvular AFIB?
Nonvalvular AFib generally refers to AFib caused by other things, such as high blood pressure or stress. There’s still some debate over how exactly to define valvular AFib. Anywhere from 4 to 30 percent of people with AFib are thought to have valvular AFib.
What causes AFIB after surgery?
Sometimes the cause of AFib is unknown. Other times, it is the result of damage to the heart’s electrical system from other conditions, such as longstanding, uncontrolled high blood pressure or coronary artery disease. AFib is also the most common complication after heart surgery.
How to define valvular atrial fibrillation?
Atrial fibrillation (AFib) is an irregular heart rhythm in which your heart flutters instead of beating. You may have heard of two types of AFib: valvular and nonvalvular.
