Resting haemodynamics, cardiac function, and patient-reported outcomes were measured before and after the intervention. Global longitudinal strain (GLS) and left atrial reservoir strain (LAr) were assessed using 2D speckle-tracking echocardiography. Patient-reported outcomes were evaluated using the Kansas City Cardiomyopathy Questionnaire (KCCQ-12). 33 (87%) participants completed the study. Isometric exercise training produced significant reductions in resting systolic (−8.52 ± 2.7 mmHg, P = 0.003), mean (−4.94 ± 2 mmHg, P = 0.018), and diastolic (−4.62 ± 1.8 mmHg, P = 0.016) blood pressure, as well as total peripheral resistance (270.4 ± 75.4 dyne s cm−5, P = 0.001) compared to usual care. Additionally, significant improvements were observed in GLS (2.18 ± 0.7%, P = 0.005), LAr (4.59 ± 1.7%, P = 0.012), LA stiffness index (−0.2 ± 0.06), and the physical limitation subscale of the KCCQ (10.27 ± 4.56, P = 0.032) following IET.</jats:p>\n                  </jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion</jats:title>\n                    <jats:p>Isometric exercise training is a feasible and safe therapeutic intervention for patients with HFpEF, with cardiovascular and quality of life improvements.
