Huang WM, Cheng HM, Yu WC, et al. - The present study was conducted to evaluate the correlation between H2FPEF score and pulmonary function, given ventilatory abnormalities prevail in subjects with Heart failure with preserved ejection fraction (HFpEF). Researchers included individuals who presented with exertional dyspnoea and had left ventricular ejection fraction of >50%. They obtained total lung capacity, forced expiratory volume in the 1 s, and forced vital capacity by pulmonary function tests. Results reveal that chronic obstructive pulmonary disease (COPD) is commonly associated with HFpEF either obstructive or restrictive ventilation defects prevail in patients with high H2FPEF score. Association was found between H2FPEF score and long‐term survival in dyspnoeic patients with or without concomitant diseases of HFpEF and COPD.
