Increased pulse pressure is associated with structural target organ damage, especially in elderly patients, increasing cardiovascular risk.


In this analysis, we investigated whether high pulse pressure retains a prognostic effect also when common markers of target organ damage are taken into account.


We analysed an unselected cohort of treated hypertensive patients from the Campania Salute Network registry (n = 7336). Participants with available cardiac and carotid ultrasound were required to be free of prevalent cardiovascular disease, with ejection fraction ≥50%, and no more than stage III Chronic Kidney Disease. The median follow-up was 41 months and end-point was occurrence of major cardiovascular events (i.e. fatal and non-fatal stroke or myocardial infarction and sudden death). Based on current guidelines, pulse pressure ≥60 mm Hg was classified as high pulse pressure (n = 2356), at the time of the initial visit, whereas pulse pressure <60 mm Hg was considered normal (n = 4980).


High pulse pressure patients were older, more likely to be women and diabetic, while receiving more antihypertensive medications than normal pulse pressure (all p < 0.0001). High pulse pressure exhibited greater prevalence of left ventricular hypertrophy, and carotid plaque than normal pulse pressure (all p < 0.0001). In Cox regression, high pulse pressure patients had 57% increased hazard of major cardiovascular events, compared to normal pulse pressure (hazard ratio = 1.57; 95% confidence interval: 1.12–2.22, p = 0.01), an effect that was independent of significant prognostic impact of older age, male sex, diabetes, left ventricular hypertrophy, carotid plaque and less prescription of anti-renin–angiotensin system therapy.


High pulse pressure is a functional marker of target organ damage, predicting cardiovascular events in hypertensive patients, even independently of well-known structural markers of target organ damage.
