Q

Does targeting systolic blood pressure under 120 reduce CVD events compared to targeting SBP under 140 in pts with type 2 DM at high risk for CVD events?

A

No! no difference in CV complications between BP under 120 and 140 in diabetics (in terms of CVD events)

21
Q

Why are thiazide diuretics preferred as initial therapy in HT?

A
  • Thiazide diuretics are effective in reducing a variety of CV hypertensive complications such as stroke, CHD and CHF by about 30-40% and to reduce all cause and cardiovascular mortality by about 10-25%.
  • Beta blockers while usually effective in reducing CV events appear to be inferior to diuretics, especially in elderly hypertensive patients and unlike diuretics do NOT significantly reduce mortality or CV mortality.
22
Q

What is the ALLHAT hypothesis/conclusion?

A

Among antihypertensive drugs, thiazide diuretics are unsurpassed in:

  • Controlling elevated blood pressure
  • Preventing cardiovascular complications
  • Since they are also least expensive, diuretics should be used as INITIAL anti-hypertensive drug therapy (alone or in combination with another drug class)
