Ischemic Heart Disease Flashcards
Angina
myocardial ischemia which usually manifests as chest pain
What are conditions that can manifest as chest pains
CAD, Vasospasm, low cardiac output state
What increases oxygen demand
Tachycardia, HTN, increased contractility
What decreased oxygen supply
anemia, hypoxemia, CAD or acute thrombosis, coronary vasospasm, hypotension
stable angina
exterional, relieved with rest or vasodilators, diseased coronary artery is dilated post-stenoisis, vasospasm could be cause
unstable angina
angina occurs at rest, coronary artery plaque rupture, considered an acute coronary syndrome (ACS)
What is the most common cause of heart disease
atherosclerotic plaque
what are risk factors for CAD
male, HTN, hypercholesterolemia, diabetes, family history, tobacco abuse, obesity
what are treatments for CAD
lifestyle changes, medica, percutaneous coronary interventions, CABG
what are medications for CAD
B-blockers, CCB, nitrates, ACE-I, ASA, Statins
What is the goal during CAD anesthetic managemetn
to maximize favorable oxygen supply and demand relationship
What do we look for on an EKG for infarction
ST segment elevation, depression, and T wave inversion
Cardiac enzymes MI
elevated levels as a result of leak from injured myocardium
Transmural MI
usually secondary to obstruction in a major coronary artery, ST elevation
Subendocardial MI
ST depression
