Exam 1: Cardiology and Covid Paper Questions Flashcards
what are the usual clinical cardiac manifestations of SARS-CoV-2?
acute myocardial infarction, acute cardiac injury, myocarditis, acute heart failure
what is hypoxia? How does it effect cardiac performance?
hypoxia: lack of oxygen in the tissue
without oxygen in the tissue you will not be able to make ATP and the heart muscle will not be able to contract properly
continuous ECG monitoring
attach electrodes to person’s body for a period of time to monitor the hearts activity
poor prognosis
bad outcome, low chance of recovery
acute myocardial infarction
blockage of blood flow to the heart
myocarditis
inflammation of the heart muscle
endothelial cells and where are they
endothelial cells: line the inside of blood vessels in the body
atherosclerotic plaque
thickening or hardening in arteries caused by deposits of fatty aubstances
How do elevated D-dimers and increased fibrin degradation lead to increased incidence of thrombus development? What is DIC?
activate the coagulation cascade
DIC = disseminated intravascular coagulation
decompensation of pre-existing left ventricular heart failure
it is no longer functioning like it used to, it is worn out
pulmonary hypertension
how is it related to cor pulmonale
high BP in arteries in lungs
cor pulmonale causes right side of heart to fail and this hypertension also creates high BP in right side of heart
malignant arrythmia
ventricular tachycardia
arrythmia: irregular heartbeat
T troponin
why is it a marker of cardiac disease?
T troponin: part of troponin complex important in contraction of heart muscle
these proteins are released when the heart is damaged, so if seen in tests it indicates damage to heart
hypokalemia
too low K in blood
increases risk of arrythmias
hyperkalemia
too high K in blood
can get irregular heartbeat
