This condensed, rapid-review study guide is built for nurses who need to master cardiovascular concepts quickly and confidently. Whether you're preparing for the ANCC CVRN certification, a cardiac unit exam, or a comprehensive cardiovascular nursing course, this guide delivers the exact facts, values, and clinical pearls that appear on tests. What's Inside: Cardiac Fundamentals Frank-Starling Law, preload, afterload, contractility, cardiac output calculations Stroke volume norms (60–130 mL), MAP formula, pulse pressure, Corrigan pulse, pulsus paradoxus S1–S4 heart sounds: causes, timing, and clinical significance Murmur grading (I–VI) with specific murmur patterns for aortic stenosis, mitral regurgitation, mitral stenosis, mitral valve prolapse, and more Coronary Anatomy & ACS LAD, RCA, circumflex territory supplies and occlusion consequences Ischemia vs. injury vs. infarct: ECG findings (ST depression, ST elevation, Q waves) Anterior, inferior, and lateral lead groupings with culprit arteries Door-to-ECG (10 min) and door-to-PCI (90 min) goals Troponin, CK-MB, and myoglobin timelines Heart Failure & Cardiomyopathy HFrEF vs. HFpEF, NYHA classes I–IV Dilated, hypertrophic, and restrictive cardiomyopathy: pathophysiology and key features BNP, s3/s4 sounds in HF, pulse alternans Hypertension & Risk Factors JNC 8 stages, first-line agents, special populations DASH diet, sodium restriction, exercise recommendations Metabolic syndrome criteria, #1 stroke risk factor (HTN) CHADS score, 5 A's of smoking cessation Vascular Disorders PAD: risk factors, ABI interpretation, claudication treatment, imaging Aortic stenosis/regurgitation, aortic dissection, AAA signs Layers of vascular anatomy, EDRF, angiotensin pathway Pacemaker settings (1st, 2nd, 3rd letters explained) Pharmacology ACE inhibitors/ARBs: benefits, side effects, acceptable creatinine rise Beta-blockers, calcium channel blockers, thiazide diuretics: adverse effects Amiodarone toxicity, aspirin in uncontrolled HTN Drugs that increase BP (NSAIDs, oral contraceptives, etc.) Shock & Critical Care Compensatory, progressive, and refractory stages of shock Hemodynamic markers, management priorities, narrowed pulse pressure as early warning Why This Guide Works: Rapid-review format: Every entry is a testable fact — no filler, no fluff Numbers that matter: Normal PT, aPTT, stroke volume, MAP, ABI cutoffs, JNC 8 thresholds Memory aids included: "SAD" for aortic stenosis, "5 A's" for cessation, "think brick wall" for restrictive cardiomyopathy 2026-updated: Reflects current guidelines and certification blueprint Guaranteed pass: Master these 130+ entries and walk into your exam with confidence Perfect for: ANCC CVRN certification candidates Critical care, telemetry, and progressive care nurses Nursing students in cardiovascular courses (NURS 4210 / NUR 465) Anyone needing a fast, high-yield cardiac-vascular refresher Instant digital download.
