Which of the following cardiac medications would be given if the indication is an acute coronary syndrome?
Anticoagulant Drugs. Either a low molecular weight heparin (LMWH), unfractionated heparin, or bivalirudin is given routinely to patients with acute coronary syndrome unless contraindicated (eg, by active bleeding or planned use of streptokinase or anistreplase).
Which class of medications commonly given to patients with acute coronary syndrome may be adversely affected by morphine?
A possible reason to explain this harmful effect is that morphine is associated with delayed activity of platelet inhibitor drugs in patients presenting with ST-elevation myocardial infarction (STEMI) [4].
What conditions are contraindications to therapy with beta blockers in patients with ACS?
Contraindications for β-blockers administration are: hypotension (systolic blood pressure < 100 mmHg), bradycardia (heart rate < 50 bpm), phenomenon Raynaud, severe pneumonopathy (especially chronic obstructive and bronchial asthma), and severe renal insufficiency.
Should be given to all patients with ACS unless contraindicated?
All patients are given aspirin 160 to 325 mg (not enteric-coated), if not contraindicated (eg, life-threatening active bleeding), at presentation and 81 mg once a day indefinitely thereafter. Chewing the first dose before swallowing quickens absorption.
When is nitroglycerin contraindicated?
Nitroglycerin is contraindicated in patients that have reported allergic symptoms to the medication. [18] Known history of increased intracranial pressure, severe anemia, right-sided myocardial infarction, or hypersensitivity to nitroglycerin are contraindications to nitroglycerin therapy.
Which of the following is a contraindication for nitroglycerin?
Nitroglycerin is contraindicated in patients who are allergic to it. Sublingual nitroglycerin therapy is contraindicated in patients with early myocardial infarction, severe anemia, increased intracranial pressure, and those with a known hypersensitivity to nitroglycerin.
Why Beta blockers are contraindicated in prinzmetal angina?
Side Effects of Beta Blockers 5 Beta blockers should also be avoided in patients with angina due to Prinzmetal’s angina (coronary artery spasm) since in these patients beta blockers can occasionally cause more spasm.
Are beta blockers contraindicated in CHF?
Beta-blockers were contraindicated in CHF because of their intrinsic negative inotropic activity, but have now been shown to be beneficial, partly due to their ability to enhance sensitivity to sympathetic stimulation.
What is one contraindication to administering nitroglycerin?
What is the difference between ACS and MI?
Acute coronary syndromes result from a sudden blockage in a coronary artery. This blockage causes unstable angina or heart attack (myocardial infarction), depending on the location and amount of blockage. A heart attack is death of heart tissue due to lack of blood supply.
Which three are contraindications for the administration of nitroglycerin?
The contraindications of nitroglycerine therapy include:
- Allergic reactions to nitroglycerin are extremely rare, but reports do exist.
- Known history of increased intracranial pressure, severe anemia, right-sided myocardial infarction, or hypersensitivity to nitroglycerin are contraindications to nitroglycerin therapy.
Why is intravenous nitroglycerin contraindicated in restrictive cardiomyopathy?
Intravenous nitroglycerin is contraindicated in patients with constrictive pericarditis, restrictive cardiomyopathy, or cardiac tamponade because the drug reduces venous return, decreases preload, and decreases cardiac output, which can be worsened in patients with these conditions.
When is nitroglycerin contraindicated in the treatment of erectile dysfunction (ED)?
Nitroglycerin is contraindicated in patients who are allergic to it and in patients who are taking phosphodiesterase inhibitors for erectile dysfunction. [ 6] Patients should not have taken a phosphodiesterase inhibitor for at least 48 hours before the exam.
What are the contraindications for sublingual nitroglycerin?
The administration of sublingual nitroglycerin dilates the coronary arteries and increases side branch visualization. [ 5] Nitroglycerin is contraindicated in patients who are allergic to it and in patients who are taking phosphodiesterase inhibitors for erectile dysfunction. [ 6]
How many doses of nitroglycerin should be given for post-NSTEMI-ACS?
For patients post-NSTEMI-ACS who experience angina lasting longer than 1 minute, the guidelines recommend 1 dose of nitroglycerin and if there is no relief within 3 to 5 minutes, the patient should be instructed to call 911 immediately.
