Median follow-up time was 80 months (mean 70\u00b133 months). Systolic pulmonary artery pressure was derived from peak velocity of tricuspid regurgitant jet plus the right atrial pressure and considered elevated if \u226540\u2009mm Hg (PH).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>During follow-up there were 123 (59%) deaths with no difference in mortality between moderate and severe TR (p=0.456). The death rates were 93 (67%) in patients with PH versus 30 (42%) without PH (p&lt;0.001). PH was associated with lower event-free survival in moderate (log-rank, p&lt;0.001), but not in severe TR (log-rank, p=0.133). In a multivariate Cox regression analysis adjusted for age, smoking, coronary artery disease, reduced right ventricle S\u2032, lower left ventricular ejection fraction at baseline, right atrium size and mitral valve replacement, PH remained a significant predictor of all-cause mortality (HR 2.22; 95%\u2009CI 1.41 to 3.47, p=0.001).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Moderate or severe TR was found in 1.6% of patients attending for routine echocardiograms.
