HF, Angina, Dysrhythmias
The principal drugs employed for treatment of heart failure are
Angiotensin-converting enzyme inhibitors (ACE), diuretics,
Remodeling is a process in which the ventricles
dilate, hypertrophy and become more spherical.
The principal adverse effects of the angiotensin-converting enzyme (ACE) inhibitors are
hypotension, hyperkalemia and cough
The oldest and most frequently prescribed inotropic drugs are the
Spironolactone has two adverse effects of concern. They are
gynecomastia and hyperkalemia.
A drug that provides a positive inotropic effect on the heart causes
increased force of contraction, thereby increasing cardiac output.
Beneficial effects of digoxin in the treatment of heart failure include
increased cardiac output, consequences of increased cardiac output, decreased sympathetic tone, increased urine output and decreased renin release.
The most common cause of dysrhythmias in patients receiving digoxin is
hypokalemia secondary to the use of diuretics.
The principal noncardiac toxicities of digoxin concern the
Gastrointestinal system and the central nervous system.
The therapeutic plasma level of digoxin is
0.5 to 0.8 ng/ml.
Is the use of antidysrhythmic drugs increasing or decreasing?
The term arrhythmia denotes a(n)______of
cardiac rhythm, whereas dysrhythmia denotes a(n)_______rhythm
Phase 3 repolarization can be delayed by drugs that block
The treatment of choice for sustained ventricular tachycardia is
The most common adverse effect of quinidine is
Lidocaine is the treatment of choice for
short term therapy of ventricular dysrhythmias__.
The major adverse effect of bretylium is
What is the current drug of choice for terminating paroxysmal supraventricular tachycardia (SVT)
What are the four families of antianginal agents?
calcium channel blockers,
The underlying cause of exertional angina is
coronary artery disease
Beta blockers are effective in which type of angina?
Eptifibatide (Integrilin) and tirofiban (Aggrastat) are used as which type of therapy?
How many hours a day should a patient receiving nitroglycerin therapy be drug-free of this medication? __
How is nitroglycerin administered via the intravenous (IV) route?
Administration should be performed using a glass IV bottle and the administration set provided by the manufacturer
Adverse effects of beta blockers include
bradycardia, decreased AV conduction, reduced contractility, insomnia, depression, bizarre dreams and sexual dysfunction.
If an asthmatic individual absolutely must use a beta blocker, which one should be administered?
Cardiac selective, metoprolol.
The major adverse effect of the calcium channel blockers is
Cardiac oxygen demand is determined by
heart rate, contractility, preload and afterload.
