Article Synopsis
- The study aimed to evaluate how B-lines, identified through lung ultrasound during stress echocardiography, relate to lung congestion and patient prognosis.
- Researchers analyzed 2,145 patients using transthoracic echocardiography and lung ultrasound, classifying B-lines into four severity groups based on their presence during stress tests.
- Findings showed that patients with severe B-lines had a significantly higher risk for adverse outcomes, including death and nonfatal myocardial infarctions, during a median follow-up period of 15.2 months.
Background: Stroke volume response during stress is a major determinant of functional status in heart failure and can be measured by two-dimensional (2-D) volumetric stress echocardiography (SE). The present study hypothesis is that SE may identify mechanisms underlying the change in stroke volume by measuring preload reserve through end-diastolic volume (EDV) and left ventricular contractile reserve (LVCR) with systolic blood pressure and end-systolic volume (ESV).
Methods: We enrolled 4735 patients (age 63.
Background: The assessment of coronary flow velocity reserve (CFVR) in left anterior descending coronary artery (LAD) expands the risk stratification potential of stress echocardiography (SE) based on stress-induced regional wall motion abnormalities (RWMA).
Objectives: The purpose of this study was to assess the feasibility and functional correlates of CFVR.
Methods: This prospective, observational, multicenter study initially screened 3,410 patients (2,061 [60%] male; age 63 ± 11 years; ejection fraction 61 ± 9%) with known or suspected coronary artery disease and/or heart failure.
