Cardio14 Flashcards
Hypertension Hyperlipidemia signs Arteriosclerosis
Definition of Hypertension.
BP ≥ 140/90 mmHg
1˚ Hypertension (essential) is associated with -
INcreased CO or INcreased TPR
*90% of cases
Other than essential HTN, what is the rest of HTN due to?
Renal disease
Malignant Hypertension.
> 180/120 mmHg
Rapidly progressing
Hypertension predisposes patients to what other conditions?
Atherosclerosis LVH Stroke CHF Renal Failure Retinopathy Aortic Dissection
Hyperlipidemia sign:
Atheromas
Plaques in blood vessel walls
Hyperlipidemia sign:
Xanthomas
Plaques or nodules composed of lipid-laden histiocytes in the skin
*especially eyelids (xanthelasma)
Hyperlipidemia sign:
Tendinous Xanthomas
Lipid deposit in tendon
*Achilles tendon most common
Hyperlipidemia sign:
Corneal Arcus
Lipid deposition in cornea
*nonspecific (arcus senilis)
What is Monkeberg?
Calcification in the media of the arteries
- especially radial or ulnar
Benign - don’t affect blood flow
“pipestem” arteries
Arteriolosclerosis types.
Hyaline
-Thickening of Small arteries in 1˚ HTN or DM
Hyperplastic
-“onion skinning” in malignant HTN
Atherosclerosis.
Fibrous plaque & atheromas form in INTIMA of arteries
Disease of Elastic arteries & large- & medium-sized muscular arteries
What process is important in the pathogenesis of atherosclerosis?
Inflammation
Describe the progression of Atherosclerosis
Endothelial cell dysfunction Macrophage & LDL accumulation FOAM CELL formation Fatty Streaks Smooth m. cell migration (PDGF & FGF) Fibrous plaque Complex atheromas
What are the common locations of Atheroscleoris (most to least)?
Abdominal Aorta > Coronary a. > Popliteal a. > Carotid a.
