- W2026069839 abstract "Purpose: Evaluation of myocardial contractility during ventricular assist device (VAD) support is important for recognizing the mechanism of myocardial recovery, but such evaluation is difficult because of the changing preload and afterload conditions. We serially investigated a load independent index and compared it with conventional indexes during VAD support in goats with severe heart failure after myocardial infarction (MI). Methods: Nine adult goats weighing 61.6 ± 5.7 kg were installed pulsatile bi-VADs. Acute MI (AMI) was created by ligation of the left anterior descending coronary artery. Ultrasonic crystals were inserted into both sides of the endocardium for measuring short axis dimension of the LV. Fractional shortening (FS), a conventional index, and end-systolic pressure-dimension relationship (ESPDR), a useful load independent index, were measured for 4 weeks after AMI using the short axis dimension and simultaneous LV pressure. Results: FS decreased for five days (from 22.4 ± 13.4% to 15.7 ± 7.9%), but it turned to improve within 1 week. However the slope of ESPDR decreased for about 2 weeks (from 27.1 ± 10.8 mm Hg/mm to 13.9 ± 7.5 mm Hg/mm), after which it fluctuated between 10 and 20 mmHg/mm. This discrepancy may mean that FS reflected the compensated movement of the non-ischemic myocardium, although the infracted myocardium continued to show deteriorating contractility. Conclusion: Serial analysis using a load independent index provides important information for recognizing myocardial recovery during VAD support." @default.
