CARDIOVASCULAR DRUGS – BCSE Study Guide

Overview and Clinical Importance

Cardiovascular drugs form a cornerstone of veterinary therapeutics, used to manage congestive heart failure (CHF), arrhythmias, and hypertension across multiple species. Understanding these medications is essential for BCSE success, as they integrate pharmacology with clinical decision-making.

The BCSE tests your ability to select appropriate cardiovascular medications based on mechanism of action, species-specific considerations, and clinical scenarios. This domain accounts for 28-32 questions (combining pharmacology, physiology, and toxicology), making cardiovascular pharmacology a high-priority study area.

Positive Inotropes

Positive inotropes increase myocardial contractility, improving cardiac output in patients with systolic dysfunction. Two agents dominate veterinary cardiology: digoxin (a cardiac glycoside) and pimobendan (an inodilator).
