The fundamental relationship between blood disorders and the cardiovascular system originates within multiple points of interface, ranging from the heart and its structural constituents to include heart chambers, valves, coronary arteries, coronary veins, and the cerebrovascular and peripheral vasculature. While the cellular components of circulating blood derive their primary origin from multipotent progenitor cells, plasma-based components, which include coagulation proteins, are mostly born of hepatic synthesis and endothelial cells. Here we provide a focused overview of nononcological blood disorders and their potential impact on the arterial circulatory system as common phenotypes, including myocardial infarction, ischemic stroke and peripheral arterial occlusive events. Venous thromboembolism is employed in our discussion as a clinical template. We also provide practical steps and guidance for diagnostic testing and management in routine clinical practice.
Blood is the medium for exchanging oxygen, nutrients, and waste products throughout the body, and consists of plasma, blood cells (red blood cells, white blood cells), and platelets. Platelets play an important role in clotting, white blood cells are responsible for inflammation, and red blood cells carry oxygen and nutrients to all tissues of the body and carry waste products away from the organs. Any abnormality of these blood components can result in hematologic disorders. While disorders involving platelets and coagulation that can lead to thrombosis and/or bleeding are of primary concern for most cardiologists, disorders involving red blood cells and platelets can also affect the mechanics of blood flow and blood viscosity. Our understanding of hematologic disorders has advanced steadily in recent years, particularly with the development of genetics and molecular biologic techniques.
