CV Disorders & Terminology Overview Flashcards
Cardiac Tamponade:
Accumulation of fluid in the pericardial sac impairs diastolic filling and reduces cardiac output; complication of MI or dissection of aorta at root.
Aneurysm:
Abnormal dilation of BV leading to weakness & rupture. Excessive bleeding and organ damage may occur
Berry Aneurysm:
a small saccular aneurysm of a cerebral artery, usually at the junction of vessels in the circle of Willis; such aneurysms frequently rupture, causing subarachnoid hemorrhage.
Congenital
an anomaly present at birth.
Phlebothrombosis
Inflammation of a vein which predisposes it to a blood clot.
Intermittent Claudication
pain and cramping in the calf with exercise due to ischemia
What is a sign of an aneurysm?
sudden sever pain in head or abdomen (brain, aorta)
What is a sign of intermittent claudication?
pain with walking that decreases with rest.
Raynaud’s disease
idiopathic (suspected d/t vascular spasm) disease, characterized by intermittent attacks of ischemia of the extremities (fingers, toes, ears, nose).
Raynaud’s syndrome
arterial spams d/t abnormal SNS firing.
Congestive heart failure (disease)
a circulatory disturbance caused by cardiac pump failure thus heart muscle doesn’t pump well d/t CAD or HTN.
Hypertrophy
Enlargement of an organ or body part due to increased cell size (usually skeletal muscle).
Hypertensive Stroke
a sudden rupture of cerebral arteries (intracranial hemorrhage).
Hypertension
an elevation of BP above the normal range for a prolonged period of time increasing the risk of stroke or heart attack.
What is considered hypertensive value?
high BP threshold is 140/90 and “dangerous” is 160/95.
Ischemic Heart Disease
Insufficient coronary blood flow leading to a heart attack (MI) - occlusion of coronary artery can lead to heart necrosis.
Eclampsia
Gravest form of toxemia of pregnancy, characterized by hypertension, renal dysfunction and seizures.
