Aim  To assess whether the simultaneous performance of exercise stress echocardiography and cardio-pulmonary testing (ESE-CPET) may facilitate the timely diagnosis of subclinical left ventricular diastolic dysfunction (LVDD) in patients with non-severe chronic obstructive pulmonary disease (COPD), preserved left ventricular systolic function, and exertional dyspnea or exercise intolerance.    Methods  This cross-sectional study, conducted between May 2017 and April 2018, involved 104 non-severe COPD patients with exertional dyspnea and preserved ejection fraction who underwent echocardiography before CPET and 1-2 minutes after peak exercise. Based on the peak E/e’ ratio, patients were divided into the group with stress-induced LVDD – E/e’>15 and the group without stress-induced LVDD. We assessed the association between LVDD and the following CPET variables: minute ventilation, peak oxygen uptake (VO 2 ), ventilatory efficiency, heart rate reserve, and blood pressure.    Results  During ESE-CPET, stress-induced LVDD occurred in 67/104 patients (64%). These patients had lower work load, peak VO 2 , O 2  pulse, and minute ventilation (VE), and higher VE/VCO 2  slope than patients without stress-induced LVDD (35.18 ± 10.4 vs 37.01 ± 11.11,  P  < 0.05). None of the CPET variables correlated with E/e’.    Conclusion  Combined ESE-CPET may distinguish masked LVDD in patients with non-severe COPD with exertional dyspnea and preserved left ventricular systolic function. None of the CPET variables was a predictor for subclinical LVDD.
