Tachycardia, hypotension, and decreased urine output are manifestations of:
shock
All of the following are major coronary arteries except:
right coronary
Arterosclerosis leads to cardiac dysfunction primarily due to:
disrupting blood flow and oxygen supply to myocardium
Chest pain which results from ischemia and narrowed blood flow to the myocardium is known as:
angina pectoris
Which mechanism explains (primarily) why congestive heart failure patients are hypoxic and short of breath?
as fluid accumulates, it floods the aveoli, decreasing gas exchange
Compression of the heart by blood and fluid in the pericardial sac is a complication occuring one week following an infarction. This typically fatal condition is known as:
cardiac tamponade
Occasionally, the right ventricle will enlarge as a response to hypertension and may lead to heart failure. This condition, which can appear on a nuclear stress test by the large appearance of the right ventricle is known as:
cor pulmonale
Occasionally following a myocardial infarction, the endocardium overlying the infarction can become damaged, leading to the formation of a thrombus on the endocardium. This condition is:
Endocardial mural thrombus
All of the following occur on the cellular level during myocardial infarction except:
the mitochondria began metabolizing glucose.
Unstable angina pectoris, or chest pain at rest, is a sign of _____________, which may lead to ______________.
coronary insufficiency; myocardial infarction
Each of the following are treatments for atherosclerosis of coronary arteries except:
nuclear stress testing
The formation of granulomas inside the heart tissue is:
cardiac sarcoidosis
The conduction disorder in which the atria fail to contract effectively, leading to pooling of blood in the heart and the formation of thrombi is ________, and it greatly increases a patients risk of stroke.
atrial fibrillation
All of the following are disorders that lead to decreased cardiac output except:
atrial fibrilation
cardiomyopathy
ventricular-septal defect
congestive heart failure
all of these result in decreased cardiac output.
Arteriosclerosis up to nearly _______% can be asymptomatic or be accompanied by angina.
40%
A coronary artery will 100% occlusion can result in the following:
myocardial infarction
congestive heart failure
death
all of the above
The adaptive reduction of myocardial contractile function in response to reduction of myocardial blood flow is known as
hibernation
Ascites, jugular vein distention, and dilated pupils are key manifestations of:
congestive heart failure
The presence of cardiac enzymes in the bloodwork indicate:
myocardial infarction
Nitroglycerin can be given to patients with angina because:
it is a vasodilator that increases blood flow to ischemic myocardium
