Combined impact of elevated arterial stiffness and left ventricular filling pressure on outcomes after off-pump coronary artery bypass grafting.

ABSTRACT:

Background

Brachial-ankle pulse wave velocity (baPWV) and early diastolic transmitral flow velocity to mitral annular tissue velocity (E/e')-which are markers of arterial stiffness and left ventricular (LV) filling pressure, respectively-have been associated with morbidity and mortality. We investigated their combined impact on postoperative complications and long-term survival of patients undergoing off-pump coronary artery bypass grafting (OPCAB).

Methods

A cohort of 164 patients were divided into four groups: baPWV ≤ 19 m/s and E/e' ≤ 15 (reference), baPWV > 19 m/s and E/e' ≤ 15 (high-PWV-only), baPWV ≤ 19 m/s and E/e' > 15 (high-E/e'-only), and baPWV > 19 m/s and E/e' > 15 (high-PWV-and-E/e'). After inverse probability treatment weighting adjustment, each group was compa
