Cardiac Meds Cheat Sheet For Nurses And Students

As a nurse or nursing student, having a solid understanding of cardiac medications is crucial for providing high-quality patient care. With so many medications available, it can be overwhelming to keep track of their indications, dosages, side effects, and interactions. That's why we've put together this comprehensive cardiac meds cheat sheet to help you quickly reference the most commonly used cardiac medications.

Cardiovascular disease is a leading cause of morbidity and mortality worldwide, and medications play a critical role in managing various cardiac conditions. As a healthcare professional, it's essential to stay up-to-date on the latest medications, their mechanisms of action, and potential side effects. In this article, we'll cover the most commonly used cardiac medications, including anti-anginals, anti-arrhythmics, beta blockers, and more.

Anti-Anginal Medications

Anti-anginal medications are used to relieve chest pain (angina) and reduce the frequency of angina attacks. These medications work by reducing myocardial oxygen demand, dilating blood vessels, or increasing blood flow to the heart.

• Nitrates: Nitrates are a class of medications that relax blood vessels, reducing myocardial oxygen demand and relieving angina symptoms.
  • Examples: Nitroglycerin, Isosorbide mononitrate, Isosorbide dinitrate
• Beta Blockers: Beta blockers reduce heart rate, contractility, and blood pressure, decreasing myocardial oxygen demand and relieving angina symptoms.
  • Examples: Metoprolol, Atenolol, Propranolol
• Calcium Channel Blockers: Calcium channel blockers relax blood vessels, reducing blood pressure and myocardial oxygen demand.
  • Examples: Verapamil, Diltiazem, Amlodipine

Anti-Arrhythmic Medications

Anti-arrhythmic medications are used to treat irregular heartbeats (arrhythmias) and prevent complications such as stroke or cardiac arrest.

• Class I Anti-Arrhythmics: Class I anti-arrhythmics block sodium channels, reducing the heart's ability to conduct impulses.
  • Examples: Quinidine, Procainamide, Lidocaine
• Class II Anti-Arrhythmics: Class II anti-arrhythmics block beta receptors, reducing heart rate and contractility.
  • Examples: Metoprolol, Atenolol, Propranolol
• Class III Anti-Arrhythmics: Class III anti-arrhythmics block potassium channels, prolonging the heart's refractory period.
  • Examples: Amiodarone, Sotalol, Ibutilide

Beta Blockers

Beta blockers are a class of medications that reduce heart rate, contractility, and blood pressure, making them useful in treating various cardiac conditions.

• Non-Selective Beta Blockers: Non-selective beta blockers block both beta-1 and beta-2 receptors, reducing heart rate, contractility, and blood pressure.
  • Examples: Propranolol, Nadolol, Timolol
• Selective Beta-1 Blockers: Selective beta-1 blockers block only beta-1 receptors, reducing heart rate and contractility without affecting airway resistance.
  • Examples: Metoprolol, Atenolol, Bisoprolol

ACE Inhibitors and ARBs

Angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) are used to treat hypertension, heart failure, and coronary artery disease.

• ACE Inhibitors: ACE inhibitors block the conversion of angiotensin I to angiotensin II, reducing blood pressure and myocardial oxygen demand.
  • Examples: Lisinopril, Enalapril, Captopril
• ARBs: ARBs block the effects of angiotensin II on blood vessels, reducing blood pressure and myocardial oxygen demand.
  • Examples: Losartan, Valsartan, Candesartan
