Assessment of cardiac performance using Tei indices in patients undergoing pulmonary thromboendarterectomy.
2002
This study was designed to evaluate left and right ventricular performance using Tei indices in patients with severe chronic thromboembolic pulmonary hypertension undergoing pulmonary thromboendarterectomy (PTE). The Doppler-derived indices are easily measurable indicators of ventricular function based on nongeometric assessment, which helps overcome some of the difficulties entailed in the geometric assessment of left ventricular (LV) and right ventricular (RV) function in pulmonary hypertension.The indices were derived for 24 patients (aged 54+/-14 years) before and after PTE. Calculation of these indices was based on the duration of two time intervals using the formula (A - B)/B, where A…
FEV1 Predicts Cardiac Status and Outcome in Chronic Heart Failure
2022
Background COPD is an established predictor of clinical outcome in patients with chronic heart failure (HF). However, little evidence is available about the predictive value of FEV1 in chronic HF. Research Question Is pulmonary function related to the progression of chronic HF? Study Design and Methods The MyoVasc study ( ClinicalTrials.gov Identifier: NCT04064450) is a prospective cohort study of HF. Information on pulmonary and cardiac functional and structural status was obtained by body plethysmography and echocardiography. The primary study end point was worsening of HF. Results Overall 2,998 participants (age range, 35-84 years) with available FEV1 data were eligible for analysis. Lin…
