Cardiopulmonary dysfunction in patients with limb‐girdle muscular dystrophy 2A

Introduction: Little is known about the frequency of cardiopulmonary failure in limb‐girdle muscular dystrophy type 2A (calpainopathy) patients, although some studies have reported severe cardiomyopathy or respiratory failure. Methods: To clarify the frequency of cardiopulmonary dysfunction in this patient population, we retrospectively reviewed the respiratory and cardiac function of 43 patients with calpainopathy. Results: Nine of the 43 patients had forced vital capacity (FVC)
