|Official Title:||Echocardiography-guided Hemodynamic (EGHEM) Management Strategy to Improve Clinical Outcomes for Elderly Patients With Left Ventricular Diastolic Dysfunction (LVDD) Undergoing Non-cardiac Surgery|
- Number of Patients who undergo dynamic heart function changes during surgery [ Time Frame: 2 years ]
We will test the hypothesis that Left Ventricular Diastolic Dysfunction (LVDD) undergoes dynamic changes perioperatively.
A. We will preoperatively identify 200 elderly subjects to provide 80% power to detect a change in LVDD undergoing noncardiac surgery using a 0.01 level two-sided paired t-test.
B. We will assess changes in LVDD in these subjects based on hourly intraoperative echocardiography data points.
- Safety of Echo-Guided Hemodynamic Management during surgery [ Time Frame: 1 year ]
We will test the hypothesis that goal-directed Echocardiography Guided Hemodynamic Management (EGHEM) used in elderly subjects with LVDD improves postoperative clinical outcomes.
A. We will determine the ability of goal-directed EGHEM to maintain or improve intraoperative LVDD.
B. We will determine the ability of goal-directed EGHEM to reduce postoperative Major Adverse Cardiac Event (MACE)
