Key result
Whole-body vibration and isometric exercise boost peak oxygen uptake ~55% in chronic coronary syndrome.
Why the study?
Exercise intolerance may persist in patients with chronic coronary syndrome despite successful PCI, and evidence regarding low-frequency whole-body vibration training remains limited.
Does a combined 8-week cardiac rehabilitation program including low-frequency whole-body vibration training and isometric exercise improve exercise capacity in a patient with chronic coronary syndrome post-PCI?

Does a combined 8-week cardiac rehabilitation program including low-frequency whole-body vibration training and isometric exercise improve exercise capacity in a patient with chronic coronary syndrome post-PCI?
A combined cardiac rehabilitation strategy including low-frequency whole-body vibration and isometric exercise safely improved cardiorespiratory fitness and metabolic health in a post-PCI patient.
May support LF-WBVT exploration in post-PCI exercise intolerance; hypothesis-generating and should not yet change practice.
BACKGROUND: Exercise intolerance may persist in patients with chronic coronary syndrome despite successful percutaneous coronary intervention. Evidence regarding low-frequency whole-body vibration training (LF-WBVT) remains limited. CASE SUMMARY: A 62-year-old woman underwent cardiac rehabilitation for reduced exercise capacity 1 year after percutaneous coronary intervention. Baseline peak oxygen uptake was 14.3 mL/kg/min. She completed an 8-week program consisting of moderate-intensity continuous aerobic training, LF-WBVT (3-9 Hz), and isometric lower-extremity resistance exercise. Peak oxygen uptake increased to 22.2 mL/kg/min, and oxygen pulse increased from 8.7 to 9.6 mL/beat. No major adverse cardiovascular events occurred. DISCUSSION: This combined strategy improved both cardiorespiratory fitness and metabolic health. The triglyceride-glucose index reduction is a novel finding, suggesting lower future cardiovascular risk. TAKE-HOME MESSAGES: LF-WBVT with isometric exercise is safe in selected patients with chronic coronary syndrome. Triglyceride-glucose index may serve as a metabolic biomarker for rehabilitation outcomes.

Pan et al. (2026) conducted a case report in chronic coronary syndrome (n=1). Low-frequency whole-body vibration training (LF-WBVT) and isometric exercise was evaluated on Peak oxygen uptake. An 8-week program of low-frequency whole-body vibration and isometric exercise increased peak oxygen uptake from 14.3 to 22.2 mL/kg/min in a patient with chronic coronary syndrome.
