associated with renal and non-renal diseases.
presence of microalbumin in the urine which is a predicament for vascular disease, HTN, kidney disease.
- more prevalent in the elderly and associated with excess mortality from CV and renal causes. p
- prognosis the same in both groups

  2. HTN / LVH
  3. Cholesterol
  4. Build
  5. Diabetes
  6. Family history
37
Q

A 
stroke 
cancer 
emphysema
Chronic bronchitis
other cause of death
39
Q

risk of developing HTN increases with Age. Why?

A

vascular distensibility and elastic recoil of arteries diminish
increases in peripheral resistance of the blood vessels
secondary causes develop: kidney and artery disorders.
- Young/old affected the same.
- controlled/ tx’ed HTN = better prognosis.

40
Q

What are the two patterns of HTN?

A
  1. isolated systolic hypertension > independant mortality risk.
  2. combined systolic/diastolic hypertension.
41
Q

What is the mortality risk of Hypotension?

A

Mortality curve is U or J shaped.
theory for why morality increases:
1. Low BP does not allow blood to perfuse vital tissues in individuals with atheroscletortic disease
2. Low blood pressure in previously hypertensive patients can be a marker of poor health resulting from another underlying disease.
- Those with hypotension w/o a prior HTN hx are good risks.

A

There is an increase in mortality risk with low serum cholesterol.
U or J shaped mortality table.
A decline in cholesterol is a red Flag for possible cancer

cancers
Cerebrovascular events
pneumonie
** unexplained weight-loss can be associated to underlying condition

45
Q

Is the CAD risk of an increase build the same amount both age groups?

A

No, the risk decreases with elevated BMI over the age of 60.
- some benefits to excess body weight to protect from falls, and supplies nutritional reserves during illness

46
Q

Does the risk of developing CAD with a history of diabetes increase or decrease as you age?

A

DM more prevalent in older ages.
