An Introduction to the Cardiovascular System and the Composition of Blood
This module identifies its basic functions and fundamental components, including the concept of a left and right heart. It also introduces you to the constituents of blood, including plasma and the various blood solids—red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
This module focuses on antihypertensive drugs, which produce their effects through differing sites and mechanisms of action; they are often used in combination to improve the overall effect. The module begins with drug classes recommended as first-line therapy in the 2017 ACC/AHA Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults. Then it describes other (secondary) antihypertensive drug classes that clinicians might draw upon if a patient’s BP goal cannot be reached using the primary agents.
Blood Vessels, Arteries, Veins, and Capillaries
Arteries and veins transport blood to and from the heart. Capillaries are the terminal points at which wastes are exchanged for nutrients. This module acquaints you with each of these vessels, and discusses how their function influences their structure.
Circulation and the Heart’s Conduction System
Circulation is the repeated movement of blood through vessels in a closed circuit through the body. Its primary purpose is to keep capillaries supplied with sufficient oxygen and other nutrients to meet the ever-changing needs of the body's cells. This module describes blood circulation and the conduction system that regulates the heart’s contractions.
Coronary Artery Disease and Acute Coronary Syndrome: Diagnosis Treatment and Prevention
This module discusses the clinical diagnosis of coronary artery disease (CAD) and acute myocardial ischemia (ie, acute coronary syndrome—ACS). It considers the treatment of angina, which is the primary symptom of CAD, and describes approaches used to treat acute myocardial ischemia. Prevention of atherosclerotic heart disease is addressed in the context of lifestyle management and lipid modifying agents.
Coronary Artery Disease and Acute Coronary Syndrome: the Cause, Risk Factors, and Symptoms
This module discusses the etiology, pathophysiology, and risk factors for CAD. It distinguishes among the categories of ACS and acquaints you with the symptoms of these atherosclerotic heart diseases.
Heart Failure (HF)
This module discusses the etiology and pathophysiology of heart failure, the body’s response to heart failure, methods for classifying the disease, patient symptoms and diagnosis, and disease management.
This module discusses some of the more commonly-used interventional procedures and outlines the role of pharmaceuticals in treating these patients.
Risk Factors and Diagnostic Tests Used in Cardiovascular Disease
This module considers the various cardiovascular risk factors—those that can be altered and those over which we have no control. It also reviews the cardinal symptoms of cardiovascular (CV) disease and acquaints you with many of the tests clinicians use to diagnose CV disease, select treatments, and evaluate treatment success.
Surgical Interventions in Cardiovascular Disease
This module acquaints you with some of the surgical procedures used commonly in cardiovascular patients and clarifies the role of pharmaceuticals in patients who undergo these procedures.
This module defines hypertension based on the 2017 ACC/AHA Guideline, and looks at risk factors and potential consequences. It describes the diagnosis of hypertension and discusses its treatment.
The Heart and Its Blood Supply
This module describes the location and anatomical structures of the heart—its layers, chambers, and valves. It also explains how the heart receives its own blood supply.
The Lymphatic System
This module acquaints you with the components of the lymphatic system, including the accessory organs (thymus, spleen, and tonsils) that assist lymphatic functions. It also explores the mechanics involved in the movement or flow of lymph.
Understanding Blood Pressure and Flow
This module discusses the cardiac cycle and the factors that determine blood pressure. It explains how a sphygmomanometer is used to measure pressure, and how pulse rate relates to heart rate and blood pressure.
