Most previous studies quantified pulsatility via blood velocity-based indices in large arteries. Here we propose an innovative method to quantify the microvascular volumetric pulsatility index (mvPI) across cortical layers and white matter (WM) using high-resolution four-dimensional (4D) vascular space occupancy (VASO) and arterial spin labeling (ASL) magnetic resonance imaging (MRI) at 7 T with simultaneous pulse recording. We assessed aging-related changes in mvPI in 11 young (28.4 ± 5.8 years) and 12 older (60.2 ± 6.8 years) participants and compared mvPI with large artery pulsatility assessed by 4D-flow MRI. mvPI peaked in the pial surface (0.18 ± 0.04). Deep WM mvPI was significantly higher in older participants (P = 0.006) than young ones. Deep WM mvPI correlated with large artery velocity PI (r = 0.56, P = 0.0099). We performed test-retest scans, non-parametric reliability test and simulations to demonstrate the reproducibility and accuracy of the method.

In skeletal muscle, these benefits are in part transcriptionally coordinated by peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α). The importance of PGC-1α to exercise-induced adaptations in the heart has been unclear. Here we show that deleting PGC-1α specifically in cardiomyocytes prevents the expected benefits from exercise training and instead leads to heart failure after just 6 weeks of training. Consistent with this, in humans, rare genetic variants in PPARGC1A, which encodes PGC-1α, are associated with increased risk of heart failure. In this model, we identify growth differentiation factor 15 (GDF15) as a key heart-secreted mediator that contributes to this dysfunction. Blocking cardiac Gdf15 expression improves cardiac performance and exercise capacity in these mice. Finally, in human heart tissue, lower cardiomyocyte PPARGC1A expression is associated with higher GDF15 expression and reduced cardiomyocyte density.

MYC directly regulates the expression of the chemokine CXCL1, which is elevated in HF-specific CFs and downregulated in Myc-deficient CFs.
