coronary artery disease - Coggle Diagram
coronary artery disease
symptoms
chest pain
contributes to
discomfort (angina)
types
stable: more common and usually occur from a trigger such as stress or exercise, and eventually stop after resting
unstable: more serious and the attacks are more unpredictable as they aren't caused by a trigger, they also don't necessarily stop after resting
-
may lead to
heart attack
classic symptoms
-
nausea, weakness, dizziness & cold sweat
-
definition
when the heart muscles don't receive enough oxygenated blood due to blockages in the coronary arteries. It is also known as myocardial infarction
-
treatment
cholesterol drugs such as statins, niacin, fibrates and bile acid sequestrants.
-
-
Angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs); lower blood pressure.
-
types
-
non-obstructive
does not cause atherosclerosis. Instead, the arteries develop other problems, such as damaged linings (endothelial dysfunction), inappropriate constriction (coronary vasospasm) malfunctions in their tiny branches (microvascular dysfunction), or squeezing from overlying heart muscle (myocardial bridging).
SCAD
when layers in the artery wall tear apart without warning, and partially or completely block blood flow to the heart
risk factors
-
sex; men have a higher risk, however it increases in women after menopause
-
-
-
chronic kidney disease; causes impaired clearance of pro-atherogenic cytokines and hormones by the kidney.
-
-
heart disease which occurs when the arteries of the heart cannot deliver enough oxygen-rich blood to the heart.
