Studies using ZSF1 rats have contributed significantly to the elucidation of pathophysiological mechanisms underlying HFpEF and therapeutic strategies against this multi-organ syndrome. In contrast, hybrid, lean ZSF1 rats (L-ZSF1) do not develop HFpEF and generally serve as controls, disregarding the possibility that the presence of one mutant Lepr allele might affect left ventricular ejection fraction (LVEF), diastolic dysfunction and other relevant HFpEF parameters, such as N-terminal pro-brain natriuretic peptide (NT-proBNP) levels and cardiac inflammation, which could increase during disease manifestation.
