We sought to define the relationship between PASP and age, to evaluate which factors influence PASP, and to determine whether PASP is independently predictive of mortality in the community.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      <jats:italic>Methods and Results\u2014<\/jats:italic>\n                    <\/jats:bold>\n                    A random sample of the Olmsted County, Minn, general population (n=2042) underwent echocardiography and spirometry and was followed up for a median of 9 years. PASP was measured from the tricuspid regurgitation velocity. Left ventricular diastolic pressure was estimated with Doppler echocardiography (E\/e\u2032 ratio), and arterial stiffening was assessed from the brachial artery pulse pressure. Among 1413 subjects (69%) with measurable PASP (age, 63\u00b111 years; 43% male), median PASP was 26 mm Hg (25th to 75th percentile, 24 to 30 mm Hg) and increased with age (\n                    <jats:italic>r<\/jats:italic>\n                    =0.31,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;0.001).
