Aneurysm
Abnormal localized dilation of blood vessel. Causes damage/pain through temp. ischemia due to reduced blood flow
Two types of aneurysm
False: does not include all layers of vessel
True:Involves all layers of vessel ie. saccular,fusiform
Aortic Aneurysm
May involve any part of aorta, most common cause atherosclerosis and breakdown of vessels tunica media
Aortic Dissection
False aneurysm, vessel wall tears open resulting in hemorrhage into space. Manifests as abrupt extreme pain described as ripping in chest
Arteriosclerosis
Means hardening of arteries, chronic disease of arterial system. Gradual thickening and hardening of vessel wall causes narrowing of artery and ischemia
Atherosclerosis
Form of arteriosclerosis.
Formation of fibrofatty lesions in between intimal lining and media. Caused by defect of or to intimal layer
Atherosclerosis Risk Factors
High cholesterol, cig smoking,obesity,age
Peripheral Vascular Disease
Chronic progressive circulation disorder. Can affect any vessels but most commonly lower extremities.
Hypertension
BP above the normal range:
systolic greater than 140 mmHg or diastolic greater than 90 mmHg
Orthostatic hypertension
refers to the increase in the blood pressure upon assuming an upright posture. Systolic rise of 20mmHg or more
Orthostatic hypotension
refers to the decrease in the blood pressure upon assuming an upright position. Systolic drop of 10mmHg within 2-5 minutes of standing.
Hypertensive Crisis
Characterized by sudden, marked elevations in blood
pressure (>180/120 mmHg) ,evidence of acute or worsening target organ damage ie. cardiac ischemia, ischemic stroke
Endocarditis
Life threatening inflammation of the inner lining of the hearts chambers and valves. Presents same as MI except also has fever present
Myocarditis
Inflammation of the heart muscle located in
between the endocardium and epicardium that
can reduce the hearts ability to pump blood. result of a viral infection
Acute Pericarditis
Acute pericarditis is defined as S/S related to inflammation of the pericardium of less two weeks. Presents as chest pain,fever,chills
Angina (angina pectoris)
sudden pain that occurs when the supply of oxygen to the myocardium is insufficient to meet the demand.
Stable Angina
Classic or exertion
angina, result of a stable
atherosclerotic plaque.
Vessels cannot dilate in
response to increased
myocardial demand
Variant Angina
also called vasospastic angina. occurs due to coronary vasospasm
Silent Myocardial
Ischemia
occurs when the heart temporarily doesn’t receive enough blood, but the
patient does not notice any effects
Acute Coronary Syndrome
Umbrella term describing any group of clinical symptoms compatible with AMI
Unstable Angina
Pain at rest or minimal activity
Pain prolonged or more severe
Pain occurring with increased frequency
Not relieved by rest or medications
Incomplete occlusion
NSTEMI (non-ST elevation myocardial infarction)
partial blockage of one of the coronary arteries, causing reduced flow of
oxygen-rich blood to the heart muscle,no ST elevation. Incomplete occlusion, biomarkers present
STEMI
Ischemic death of myocardial tissue with ST elevation seen. Result of complete occlusion. biomarkers present
Congestive heart failure (CHF)
Term for left sided heart failure, left sided failure leads to right sided failure
