The role of MW in predicting the first hospitalization for de novo heart failure with preserved ejection fraction (HFpEF) is still unknown.

MW was derived as the area of pressure\u2013strain loop using speckle-tracking and brachial artery blood pressure. Global work index, global constructive work, global wasted work (GWW), and global work efficiency (GWE) were collected. First HFpEF hospitalization and its combination with cardiovascular death [major adverse cardiovascular events (MACE)] and all-cause of death [major adverse events (MAE)] were assessed. At baseline, future HFpEF patients showed lower global work index, global constructive work, GWE, and higher GWW than controls (all P &amp;lt; 0.05). At admission vs. baseline, GWE significantly decreased, and GWW increased in the HFpEF group (P &amp;lt; 0.05), whereas no significant difference was observed in the controls over time. GWW, with a cut-off of 170 mmHg%, showed the largest area under the curve (AUC) to predict first HFpEF hospitalization [AUC = 0.80, 95% confidence interval (CI) 0.69\u20130.91, P &amp;lt; 0.001], MACE (AUC = 0.80, 95% CI 0.66\u20130.90, P &amp;lt; 0.001), and MAE (AUC = 0.79, 95% CI 0.62\u20130.88, P = 0.001). GWW &amp;gt; 170 mmHg% was associated with a 4-fold increase of MACE (HR = 4.5, 95% CI 1.59\u201313.12, P = 0.005) and a 3-fold higher risk of MAE (HR = 2.9, 95% CI 1.24\u20136.6, P = 0.014).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In ambulatory patients with preserved LV ejection fraction and risk factors, GWW showed high accuracy to predict the first HFpEF hospitalization and its combination with mortality.
