Arteriosclerosis definiton

Definition of Arteriosclerosis Arteriosclerosis is a degenerative condition of the arteries in which the walls of the arteries become stiff and rigid. Arteriosclerosis is a leading factor in age-related hypertension (high blood pressure). There are three forms: Atherosclerosis in which arterial plaque deposits infiltrate the inner layer of the arterial wall Mönckeberg’s arteriosclerosis or medial calcific sclerosis, in which the […]

Hypotension – Definition, Symptoms and Treatment

Definition of Hypotension Below-normal blood pressure. Hypotension is most often a side effect of medications, a complication of heart attack, the result of significant blood loss, or a component of cardiovascular shock. Factors that decrease the flow of blood through the body typically result in reduced blood pressure. Idiopathic hypotension (hypotension that exists without apparent cause) often […]

Rheumatic Heart Disease – Symptoms and Treatment

Definition of Rheumatic Heart Diseases Rheumatic Heart Disease is damage to the valves of the heart as a consequence of rheumatic fever, which develops as a complication of untreated or undertreated strep throat. Streptococcal bacteria attack the heart valves, most commonly the mitral and aortic valves, which can leave them scarred and deformed. Rheumatic fever and […]

Arteriovenous Malformation (AVM) – Symptoms and Treatment

Definition of Arteriovenous Malformation (AVM) Arteriovenous Malformation (AVM) is a congenital deformity in which an entanglement of arteries and veins forms.  Rather than connecting into capillary beds that form between them, the arteries and veins in an arteriovenous malformation connect directly to one another. Veins lack the structure to accommodate the pressure blood is under as it flows through […]

Intermittent Claudication – Symptoms and Treatment

Definition of Intermittent Claudication Intermittent Claudication is pain in the lower legs that occurs with physical activity such as walking. Intermittent claudication is the primary symptom of peripheral vascular disease (pvd), which is atherosclerosis that affects the arteries of the legs. The atherosclerotic accumulations of PVD occlude (block) blood flow through the arteries, limiting their ability to respond to the increased […]

Sick Sinus Syndrome – Symptoms and Treatment

Definition of Sick Sinus Syndrome Sick Sinus Syndrome is a collective term for arrhythmia disorders that arise from dysfunction of the sinoatrial (sa) node and the electrical conduction network within the heart. The SA node may stop functioning, or there may be a disruption in the pathway for the electrical impulses the SA node generates. Generally sick sinus […]

Bundle Branch Block – Left / Right and ECG (EKG)

Definition of Bundle Branch Block Bundle Branch Block – An impediment, partial or complete, that prevents electrical impulses from traveling along the bundle of his or one of the bundle branches, right or left, in the heart. The bundle branches focus and intensify the pacing signals that originate in the sinoatrial (sa) node, concentrating them enough to stimulate […]

Ischemic Heart Disease (IHD) – Symptoms and Treatment

Definition of Ischemic Heart Disease (IHD) Ischemic Heart Disease (IHD) – The consequential condition that results when coronary artery disease (cad) and other conditions that affect the heart’s blood supply deprive the heart of oxygen over an extended period of time. Ischemia is the medical term for a temporary interruption of blood flow; in ischemic heart disease (IHD), the interruptions are […]

Stroke – Symptoms, Causes, Recovery and Treatment

Definition of Stroke An interruption of blood flow and oxygen supply to the brain, sometimes called a brain attack. Stroke strikes about 700,000 Americans each year. For two thirds of them the stroke is a second or subsequent stroke. About 85 percent of strokes are ischemic; they result from blockage of an arterial pathway in […]

Cardiomyopathy – Definition, Types, Symptoms and Treatment

Definition of Cardiomyopathy Cardiomyopathy is weakness and loss of pumping effectiveness of the heart, usually with changes to the structure of the heart and in particular the left ventricle. Cardiomyopathy is as likely to affect people under age 40 as people over age 60 and is a leading cause of heart failure resulting in heart transplantation. Genetic factors can […]
