  • Title: [Systolic hypertension-treat or not to treat?].
    Author: Offers E, Kolloch RE.
    Journal: Herz; 2003 Dec; 28(8):702-6. PubMed ID: 14689104.
    Abstract:
    UNLABELLED: HEMODYNAMICS: Elevated diastolic as well as elevated systolic blood pressure substantially contribute to the increase of cardiovascular risk. Conclusive results have proven that lowering diastolic and/or systolic blood pressure can reduce cardiovascular risk. There is evidence that not only the absolute values for diastolic and systolic blood pressure alone but also the pulse pressure as an additional indicator of cardiovascular risk have to be considered. The prevalence of isolated systolic hypertension increases with age. Remodeling of the arterial wall with increase of collagen and decrease of elastic fibers are leading to an impaired arterial compliance. Decreased compliance and acceleration of the pulse wave velocity can elevate systolic and lower diastolic blood pressure. In consequence cardiac stress and pulse pressure will rise. CONCLUSION: There is a strong correlation in elderly patients between cardiovascular mortality and morbidity and systolic blood pressure. Antihypertensive therapy is able to lower cardiovascular event rate in elderly patients with isolated systolic hypertension with a predominant risk reduction for stroke.
