Chronic Management of Hypertension after Stroke: The Role of Ambulatory Blood Pressure Monitoring

Abstract

The authors have no financial conflicts of interest.Hypertension is the most important potentially reversible risk factor for stroke in all age groups; high blood pressure (BP) is also associated with increased risk of recurrent stroke in patients who have already had an ischemic or hemorrhagic event. Twenty-four hour ambulatory BP monitoring (ABPM) has become an important tool for improving the diagnosis and management of hypertension, and is increasingly used to assess patients with hypertension. Nevertheless, although ABPM devices are increasingly used for assessment of hypertension, their value in the chronic management of hypertension in patients with stroke has not been systematically studied. In fact, among large-scale randomized trials for secondary stroke prevention, only the Morbidity and Mortality After Stroke, Eprosartan Compared With Nitrendipine for Secondary Prevention trial included 24-hour ABPM. ABPM has demonstrated chronic disruption of the circadian rhythm of BP after acute phase of stroke and has shown higher sensitivity compared to office BP in evaluating the effectiveness of antihypertensive treatment among stroke survivors. High 24-hour BP is an independent predictor for cerebrovascular events, brain microbleeds, and subsequent development of dementia. Nevertheless, although stroke care guidelines endorse the importance of hypertension management, the specific role of ABPM among stroke survivors after the acute phase of disease has not been established. Further studies are needed to clarify whether routine application of ABPM among these patients should be recommended.

Early Assessment of the Risk Factors for Diabetic Retinopathy Can Reduce the Risk of Peripheral Arterial and Cardiovascular Diseases in Type 2 Diabetes

“…As is known, endothelial cells covering the inner surface of the vessel wall can produce, activate, and release various vasoactive substances during the fluctuation of BP, which further results in structural and functional changes in the aorta and arterioles [36][37][38]. The increase of SBP is also due to a decrease in arterial elasticity and vascular compliance (the early pathological changes of PAD and CVD), and high BP is associated with stroke and acute coronary events [39][40][41]. Altogether, our findings indicated that patients with DR are more likely to suffer from PAD (Tables 2-4) and that ABI and duplex ultrasonography are similarly useful for an early diagnosis of PAD in patients with DR, which can subsequently contribute to reducing the incidence of CVD.…”

Hypertension Awareness, Treatment, and Control in Mexico: An Opportunistic Medical Student-led Blood Pressure Screening Campaign – A Cross-sectional Study

“…These findings could suggest that patients with a history of stroke and MI in this population were not adequately controlled, even though hypertension is the most important factors for stroke recurrence. 22 However, a J-curve phenomenon has been described 23 in which a permissible BP target should be achieved to prevent that controlling such factor becomes inversely related to risk. On the contrary, evidence suggests that prompt, long-term BP control is imperative to improve secondary prevention of MI.…”

Stroke epidemiology based on experience from Krasnik county in eastern Poland

“…The relapse frequency depends on the subtype of stroke and is the highest in patients who have suffered from stroke due to embolism of cardiac origin, and in cases of a significant stenosis of the carotid arteries [27]. At the same time, high blood pressure is a high-risk factor for patients in all age groups, which further increases the risk of recurrent stroke [65,66,67].…”
