This study presents a reliable index inspired by the total variability concept of real analysis in mathematics, called average (ARV), for prognostic significance blood pressure (BPV) overcoming pitfalls commonly used standard deviation (SD).Recent studies have suggested that an increase BPV is associated with subsequent cardiovascular events/complications. However, there are other where cited association was not found or lost presence well-known risk factors. An explanation these apparently...

Outcome-driven recommendations about time intervals during which ambulatory blood pressure should be measured to diagnose white-coat or masked hypertension are lacking. We cross-classified 8237 untreated participants (mean age, 50.7 years; 48.4% women) enrolled in 12 population studies, using ≥140/≥90, ≥130/≥80, ≥135/≥85, and ≥120/≥70 mm Hg as thresholds for conventional, 24-hour, daytime, nighttime pressure. White-coat was on conventional measurement with normotension, the opposite...

The monitoring and processing of electrocardiogram (ECG) beats have been actively studied in recent years: new lines research even developed to analyze ECG signals using mobile devices. Considering these trends, we proposed a simple low computing cost algorithm process an signal. Our approach is based on the use linear regression segment signal, with goal detecting R point wave later, separate signal periods for P, Q, S, T peaks. After pre-processing reduce noise, was able efficiently detect...

Average real variability (ARV) is a recently proposed index for short-term blood pressure (BP) variability. We aimed to determine the minimum number of BP readings required compute ARV without loss prognostic information. was calculated from discovery dataset that included 24-hour ambulatory measurements 1,254 residents (mean age = 56.6 years; 43.5% women) Copenhagen, Denmark. Concordance between full (≥80 readings) and randomly reduced recordings examined, as accuracy. A test 5,353 subjects...

Evidence-based thresholds for risk stratification based on pulse pressure (PP) are currently unavailable. To derive outcome-driven the 24-hour ambulatory PP, we analyzed 9938 participants randomly recruited from 11 populations (47.3% women). After age (<60 versus ≥60 years) and using average as reference, computed multivariable-adjusted hazard ratios (HRs) to assess by tenths of PP distribution or associated with stepwise increasing (+1 mm Hg) levels. All adjustments included mean...
