| Popis: | A ratio15 between the early diastolic pulsed Doppler velocities of the mitral inflow (E) and the basal left ventricular (LV) tissue (e) has been demonstrated to predict an elevated LV filling pressure (FP). An elevated LVFP implies an elevated right ventricular pressure (RVp). In order to investigate the sensitivity of the E/e filling index, we compared E/e and RVp, in their ability to identify a Doppler-assumed elevation of LVFP.Application of pulsed Doppler international recommendations grouped 134 patients with acute coronary syndromes (ACS) and 50 age- and sex-matched controls, according to LV filling: normal; delayed relaxation; an isolated pathological mitral-pulmonary venous-A-wave-duration difference; pseudo normal; or a restrictive filling pattern. An E/e15 and an RVp30 mmHg showed the following (%) sensitivity (32/94), specificity (95/76), positive (68/59), and negative (80/97) predictive values of a Doppler-assumed elevation of LVFP, in terms of either a pseudo normal or a restrictive filling pattern.The low sensitivity of E/e to detect a Doppler-assumed elevation of LVFP could limit its clinical usefulness as a single variable, in ACS. The high sensitivity and negative predictive value of RVp support its use as an additional LV filling variable in these patients. |
