Echocardiographic assessment of pulmonary arterial pressure in the follow-up of patients with pulmonary embolism

An epidemiological analysis of the burden of chronic thromboembolic pulmonary hypertension in the USA, Europe and Japan

“…The proportion of patients who develop CTEPH following PE was reported in eight studies conducted in Europe and the USA [17,[45][46][47][48][49][50][51]. Japanese data were back-calculated, and further data were obtained from databases/registries.…”

External validation of a simple non-invasive algorithm to rule out chronic thromboembolic pulmonary hypertension after acute pulmonary embolism

“…[2;3] The exact prevalence of CTEPH in patients who have suffered acute PE is debated: most studies report cumulative rates of 0.57% to 4.0% within the first 2 years after PE diagnosis, depending on patient selection and diagnostic criteria. [4][5][6][7][8] Screening programs for CTEPH after an episode of acute PE are still at a preliminary stage, and their cost effectiveness remains a subject of debate. Identification of patients at risk and the optimal diagnostic tools for screening are unclear, and effective CTEPH-prevention measures are unknown.…”

Echocardiographic evolution of pulmonary artery pressure after acute pulmonary embolism. Results from IPER registry

“…In spite of the low accuracy of echo-Doppler to correctly measure the degree of PH [4,5], echocardiography remains to date the most utilized and often the only method to investigate, both in the acute phase and over time, the course of pulmonary artery systolic pressure (PAsP). Several studies considered the echocardiographic follow-up at least 6 months after an episode of acute PE [6][7][8][9][10][11][12][13][14]. Some of them [13,14] correlated the value of echocardiographycally derived PAsP in the acute phase with the persistence of PH 12 or 16 months later.…”
