Key result
Lower preoperative epicardial circumferential strain linked to ~24% higher postoperative risk in constrictive pericarditis.
Why the study?
Early postoperative complications like refractory hypotension and congestive heart failure occur after pericardiectomy for constrictive pericarditis, but whether LV myocardial strain measured by 2DSTE could identify early dysfunction and adverse events was unclear.
Is preoperative left ventricular myocardial strain associated with acute postoperative refractory hypotension in patients with constrictive pericarditis and preserved ejection fraction?
Case-Control (n=88)
Is preoperative left ventricular myocardial strain associated with acute postoperative refractory hypotension in patients with constrictive pericarditis and preserved ejection fraction?
Odds Ratio: 1.236 (95% CI 1.044–1.464)
p-value: p=0.014
Preoperative epicardial circumferential strain is independently associated with early postoperative refractory hypotension in patients with constrictive pericarditis and preserved ejection fraction.

May support preoperative strain assessment for refractory hypotension risk in constrictive pericarditis; hypothesis-generating and requires prospective validation.
Wang et al. (2018) conducted a case-control in Constrictive pericarditis with preserved ejection fraction (n=88). Lower epicardial circumferential strain vs. Higher epicardial circumferential strain / Controls was evaluated on Composite of postoperative refractory hypotension, congestive heart failure and cardiogenic death (OR 1.236, 95% CI 1.044-1.464, p=0.014). Lower preoperative epicardial circumferential strain was independently associated with postoperative adverse outcomes in patients with constrictive pericarditis (OR 1.236; 95% CI 1.044-1.464; P=0.014).
