心血管危险度分层的重要性 (一)
高血压常常伴随其它危险因素
降压治疗的目的是减少心血管发病与死亡
( CVD Risk),而不仅是降低血压( RFs),所以对心血管危险的估算是不可或缺的
血压升高是 CVD RR 的重要指标,故以往只看血压水平决定治疗策略。此法对中重度高血压行之有效,对轻度高血压则否心血管危险度分层的重要性(二)
NHANES-I根据 JNC VI,对 7,090NHEFS队列 20
年随访说明临床决策不仅依靠平均血压水平,并需考虑其他危险因素
1999年医院门诊人群高血压抽样调查报告表明,对门诊高血压患者的危险度评估中,如果只注意血压水平,是很不够的,会明显低估危险度,必须全面评估其他危险因素,才能作出正确的判断,
Problems With a Strategy Based on
Absolute Cardiovascular Risk
F,Olaf Simpson/Journal of Hypertension 1996,Vol 14 No 6
The proposed New Zealand guidelines,the 10-year absolute
CVD risk strategy
Consequences of the 10-year absolute-risk strategy
Possible age-related modifications of the 10-year
absolute-risk strategy
Problems raised by inclusion of other risk factors in the
calculations
Problems in calculation of the expected gains from
antihypertensive therapy
Problems in calculations of CVD risk from raised blood pressure
Article 1
Cardiovascular risk evaluation:
an inexact science ( 1)
Failure to consider the full risk of the
‘metabolic syndrome’ in current guidelines
Failure to appreciate the total benefit of
antihypertensive therapy
Excessive weighting of advanced age in the
assessment of cardiovascular risk
How accurate is current risk assessment for
uncomplicated mild hypertension?
Although the absolute risk assessment
methods may lack sufficient sensitivity,
they still represent an improvement over
that only the level of blood pressure and
prior cardiovascular disease were relevant to
therapeutic-decision making,To date,
cardiovascular risk evaluation is an inexact
science.
Cardiovascular risk evaluation:
an inexact science ( 2)
Enhancing risk stratification in hypertensive
subjects,How far should we go in routine
screening for target organ damage?
First,it appears timely to include the search for
microalbuminuria as a routine component of the
work-up of all hypertensive patients worldwide;
Second,it seems reasonable to recommend that
the search for target organ damage should extend
to cardiac and carotid ultrasound for high risk and
very high risk hypertensive subjects.
