Short-term blood pressure variability and long-term blood pressure variability: which one is a reliable predictor for recurrent stroke

Aim. To assess the short-term and long-term variability of blood pressure in women, starting from early pregnancy, to predict the development of complications of gestation, including preeclempsia. Methods. In 131 pregnant women, systolic blood pressure, diastolic blood pressure, as well as short-term (intra-visit) and long-term (inter-visit) blood pressure variability were assessed during the gestation period and 6 weeks after delivery. At the end of gestation period, depending on the identified complications, all study participants were divided into four groups: group 1 - control (healthy); group 2 - pregnant with preeclempsia; group 3 - with placental insufficiency; group 4 - with chronic arterial hypertension. In patients with placental insufficiency the indices of fetal growth retardation were also analyzed. Results. In group 4, starting from the second trimester, higher values of short-term blood pressure variability were demonstrated, which increased as pregnancy progressed. Long-term blood pressure variability increased in groups 2 and 4, starting from the second trimester. In pregnant women with fetal growth retardation in the first trimester, blood pressure variability was higher than in pregnant controls and in the second trimester it was higher than in the group with the subsequent development of preeclempsia. Thus, during pregnancy complicated by preeclempsia or placental insufficiency with fetal growth retardation, high long-term blood pressure variability was observed. At the same time, the highest values were observed in the third trimester. Conclusion. The assessment of long-term blood pressure variability from the early gestation seems to be an effective tool for detecting preclinical changes in the body of a pregnant woman, preceding the development of preeclempsia and fetal growth retardation, and in the presence of risk factors of preeclampsia allows narrowing the group of patients for target follow-up and prevention.

Relevant Risk Factor

Abstract Arterial blood pressure (BP) is a continuous variable, with a physiology characterized by significant variability stemming from the complex interaction among haemodynamic factors, neuronal reflexes, as well as hormonal, behavioural, and environmental stimuli. The homoeostatic response accounts for the physiologic variability in BP in normotensive individuals, which is more evident in hypertensive patients. Blood pressure variability is a complex phenomenon, which could be classified in various types: very short term (beat to beat), short term (during 24 h), mid-term (day by day), long term (<5 years), and very long term (>5 years). Accurate measurement of BP variability represents a complex and often controversial endeavour, despite several methodological approaches are available. Albeit a prognostic significance has been demonstrated for some indicators of BP variability, the clinical significance of this measurement is still uncertain. In fact, none of the indicators presently available for BP variability, including early morning BP rise, substantially affects, and redefines, the cardiovascular risk of the hypertensive patient, over and beyond the mere BP values. Accordingly, in defining the cardiovascular risk, the focus should be on the absolute BP values, which remain the most relevant risk factor, and the one more susceptible to modification with both non-pharmacologic and pharmacologic treatment.

Predictive Capacity

Abstract Background Whether blood pressure variability (BPV) measured with ambulatory monitoring (short-term BPV) or computed from office visits (long-term BPV) are related to each other and carry similar prognostic information is not well known. We investigated the independent determinants of short-term and long-term BPVs and their predictive capacity for the development of major adverse cardiovascular and renal events (MACEs) in a cohort of young hypertensive participants. Methods Long-term BPV was calculated as visit-to-visit SD and average real variability from office blood pressure (BP) measured during 7 visits, within 1 year. Short-term BPV was calculated as weighted 24-hour SD and coefficient of variation. Hazard ratios (HRs) for risk of MACE were computed from multivariable Cox regressions. Results 1,167 participants were examined; mean age was 33.1 ± 8.5 years. Variables independently associated with 24-hour systolic SD were 24-hour systolic BP, low physical activity, smoking, baseline office pulse pressure, systolic BP dipping, and diastolic white coat effect, while those associated with long-term BPV were mean systolic BP, age, female gender, and baseline office heart rate. During a median follow-up of 17.4 years 75 MACEs occurred. In Cox analysis only short-term BPV resulted a significant predictor of MACE (HR, 1.31 (1.07–1.59); P = 0.0086), while no index of long-term BPV was independently associated with outcome. Conclusions In young hypertensive subjects only short-term BPV resulted a significant predictor of MACE on top of traditional ambulatory BP monitoring parameters. Whether reduction of short-term BPV with therapy may reduce the cardiovascular risk independently from the effects on 24-hour BP is a matter for future research.

Blood pressure variability (BPV) is considered nowadays a novel risk factor for cardiovascular disease. Early findings in sinoaortic denervated rats have clearly shown that enhanced fluctuation of blood pressure induced left ventricular hypertrophy, vascular stiffness, and renal lesion. A large number of clinical trials confirm that short-term and long-term blood pressure variability independently contributes to target organ damage, cardiovascular events, and mortality not only in hypertensive patients but also in subjects with diabetes mellitus and chronic kidney disease. Therefore, amelioration of BPV has been suggested as an additional target of the treatment of cardiovascular diseases. Preliminary evidence obtained from meta-analysis and controlled clinical trials has shown that antihypertensive classes differ in their ability to control excessive BP fluctuations with an impact in the prevention of cardiovascular events. Calcium channel blockers seem to be more effective than other blood pressure lowering drugs for the reduction of short-term and long-term BPV. In order to increase actual knowledge regarding the prognostic value and therapeutic significance of BPV in cardiovascular disease, there is a need for additional clinical studies specifically designed for the study of the relevance of short-term and long-term BPV control by antihypertensive drugs.
