Abstract

BACKGROUND:

Pulse pressure (PP) provides valuable prognostic information in specific populations, but few studies have assessed its value on cardiovascular outcomes in a broad, worldwide population.

OBJECTIVES:

The aim of this study was to determine whether PP is associated with major adverse cardiovascular outcomes, independently of mean arterial pressure.

METHODS:

Participants from the international REACH (Reduction of Atherothrombosis for Continued Health) registry, which evaluates subjects with clinical atherothrombotic disease or risk factors for its development, were examined. Those with incomplete 4-year follow-up or PP data (final n = 45,087) were excluded. Univariate and multivariate regression analyses were performed to determine the association between PP and cardiovascular outcomes, including cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, all myocardial infarction, all stroke, cardiovascular hospitalization, and a combined outcome. PP was analyzed as a continuous and categorical (i.e., by quartile) variable.

RESULTS:

The mean age of the cohort was 68 ± 10 years, 35% were women, and 81% were treated for hypertension. The mean blood pressure was 138 ± 19/79 ± 11 mm Hg, rendering a mean PP of 49 ± 16 mm Hg. On univariate analysis, increasing PP quartile was associated with worse outcomes (p < 0.05 for all comparisons). After adjusting for sex, age, current smoking status, history of hypercholesterolemia, history of diabetes, aspirin use, statin use, blood pressure medication use, and mean arterial pressure, PP quartile was still associated with all outcomes except all stroke and cardiovascular death (p < 0.05 for all comparisons). Analysis of PP as a continuous variable yielded similar results.

CONCLUSIONS:

In an international cohort of high-risk subjects, PP, a readily available hemodynamic parameter, is associated with multiple adverse cardiovascular outcomes and provides prognostic utility beyond that of mean arterial pressure.
