Echo with TDI was operated (Vivid 7, G.E.). NT-proBNP levels were measured (Elecsys 2010, Roche).Results: IPH, CTD and CHD pts had the most increased right and decreased left heart chambers and RV EF accordingly to SPAP, but the highest NTpro-BNP was in CTD. Em from lateral tricuspid ring in IPH was less than in others (p<0,05). But in CTD RV Em from base and apex were comparable with IPH, from middle - the smallest. Em decreased from base to apex in all PH groups.View this table:Table 1. Echo parameters and NT-proBNP levels in PH and controlsConclusion: TDI can be a useful tool for detection early DD in PH. Sensitivity of regional TDI to RV DD was comparable with global. ER -
