Chinese Abstract

本文的目的在探討踏車式心肺功能運動測試對於急性期後腦中風患者的應用及腦中風患者在急性期後的心肺運動功能的評估分析。19位平均年齡為62.7±9.2歲的腦中風患者,在平均腦中風後9.9±2.0天,進行漸增式心肺運動功能測試。以開放式肺量計量測標準直立式踏車運動的尖峰心肺運動能力。平均尖峰攝氧量為11.8 mL/kg/min,尖峰心跳率為年齡決定預測最大心跳率的67.9±3.4%,尖峰氧氣心搏量為7.5 mL/beat。無氧閥值為尖峰攝氧量的73.4%。平均尖峰每分鐘換氣量為42.1L/min,呼吸儲備值為48.1±16.8%。本研究顯示在腦中風後2週內即可用踏車式運動測試評估患者的心肺運動功能,及患者的心肺運動能力是受損的。而肺功能障礙可能並不是造成急性期後腦中風患者心肺運動能力障礙的成因。

English Abstract

The purpose of this study was to evaluate the feasibility and exercise capacity of cycle ergometry exercise testing and exercise performance in patients with post-acute stroke. Nineteen male patients (mean age, 62.7±9.2 years) with a post stroke interval of 9.9±2.0 days underwent symptom-limited cardiopulmonary exercise testing. Peak exercise capacity was measured by open-circuit spirometry during standard upright ergometer cycling. The mean peak oxygen uptake was 11.8 mL/kg/min, peak heart rate with age-predicted maximal heart rate was 67.9±3.4%, and peak oxygen pulse was 7.5 mL/beat. The anaerobic threshold was achieved with a mean peak oxygen uptake of 73.4%. Mean peak minute ventilation was 42.1 L/min, and ventilatory reserve was 48.1±16.8%. Our findings confirm that cycle ergometry exercise testing is feasible and exercise capacity is compromised in post-acute stroke survivors within 2 weeks after stroke. Respiratory impairments do not appear to contribute to the reduced exercise capacity post stroke.
