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.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
