However, whether or not a patient can tolerate additional intravascular volume is controversial and optimal strategy is unknown.

All subjects underwent transthoracic echocardiography, pulmonary ultrasound assessment, and a cfPWV study (S. Giovanni Bosco Hospital in Turin, Italy, between 2015 and 2016) at baseline and after 24\u2009hours. Acute outcomes were registered at 24\u2009hours (\u201csoft\u201d end points) and 30 days ('hard' end points: death, acute myocardial infarction, stroke, occurrence of atrial fibrillation, need for dialysis) after initial fluid therapy. Multivariate logistic regression was used to assess association of the initial cfPWV with outcomes.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>cfPWV was significantly higher (10.6\u00b13.6 vs 7.4\u00b12.2\u2009m\/s, P&lt;0.0001) in subjects who met the prespecified combined endpoints (hard or soft) than in those who did not. After adjustment for confounding factors, initial cfPWV was significantly and independently associated with the occurrence of hard events (OR=2.8 (95% CI 1.36 to 5.97), P=0.005; area under the receiver operating characteristic curve 84%). cfPWV of &lt;9\u2009m\/s had a negative predictive value of 93%, excluding hard events associated with fluid expansion.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>cfPWV appears to reflect the ability of the patient to tolerate an intravascular fluid expansion when clinically indicated.
