What is the difference between obstructive and nonobstructive coronary artery disease?
Regardless of definition and terminology, it is necessary to emphasize that obstructive coronary disease (CAD) indicates stenosis of coronary vessel ≥50% on coronarography, while nonobstructive coronary disease (non-CAD) indicates stenosis of coronary artery <50% (11).
What does non-obstructive mean?
Medical Definition of nonobstructive : not causing or characterized by obstruction (as of a bodily passage) nonobstructive renal calculi.
What does mild non-obstructive CAD mean?
Consistent with standard definitions of flow-limiting stenoses,18–20 nonobstructive CAD was defined as a coronary artery stenosis 20% or greater but less than 50% in the left main coronary artery or a stenosis 20% or greater but less than 70% in any other epicardial coronary artery, as recorded by the clinician in the …
What causes non-obstructive CAD?
They recognize that your heart’s arteries sometimes suffer from non-obstructive coronary artery disease. This less common form of CAD occurs when your heart’s arteries inappropriately constrict, malfunction after branching into tiny vessels, or are squeezed by the overlying heart muscle.
What is non atherosclerosis?
Non-atherosclerotic carotid disease is an uncommon group of angiographic defects. It includes the entities: Takayasu’s arteritis, giant cell arteritis, fibromuscular dysplasia, moyamoya syndrome, arterial dissection and extracranial carotid aneurysms.
What is a non obstructive renal calculus?
Kidney stones that block the flow of urine from the kidney or down the ureter are called obstructive kidney stones. Depending on stone size and location the blockage can be complete or partial. Non-obstructing stones do not block urine flow but can also cause symptoms that are commonly associated with kidney stones.
What is non-obstructing nephrolithiasis?
Brief Summary: Pain associated with renal stone disease is typically caused by an obstructing stone that obstructs the flow of urine, which results in renal collecting system dilatation. Non-obstructing renal calculi that do not cause renal collecting system dilatation are thought to be painless.
Is non-obstructive coronary artery disease considered ischemic heart disease?
Ischaemia with no obstructive coronary arteries (INOCA) is a common ischaemic heart disease with a female preponderance, mostly due to underlying coronary vascular dysfunction comprising coronary microvascular dysfunction and/or epicardial coronary vasospasm.
Can a non-obstructive CAD cause angina?
As with arteries narrowed or blocked by plaque (atherosclerosis), chest pain, or angina, is a common symptom of non-obstructive coronary artery disease. This chest pain will usually occur during physical activity or with emotional stress.
What is non atherosclerotic coronary dissection?
Nonatherosclerotic spontaneous coronary artery dissection (NA-SCAD) is underdiagnosed and an important cause of myocardial infarction in young women. The frequency of predisposing and precipitating conditions and cardiovascular outcomes remains poorly described.
Does atherosclerosis increase blood pressure?
If you have atherosclerosis in the arteries leading to your kidneys, you develop high blood pressure or kidney failure.
