Abstract:

Objective To review the clinical characteristics and capacity of cardiopulmonary exercise test in patients with intermediate coronary stenosis.

Methods From January, 2015 to January, 2020, the patients underwent coronary angiography and cardiopulmonary exercise test in Beijing Bo'ai Hospital were divided into intermediate coronary stenosis group (n = 184) and non-coronary heart disease group (n = 73). Symptoms, general information, laboratory and echocardiography information, results of cardiopulmonary exercise test were compared between two groups, and the main cardiovascular events during a year were observed.

Results The proportion of male (χ2 = 15.857, P < 0.001), smoking history (χ2 = 9.067, P= 0.003), hypertension history (χ2 = 15.087, P < 0.001) and hyperlipidemia history (χ2 = 13.507, P < 0.001) were more, and the level of hemoglobin A1c (Z= 2.431, P= 0.015) and high sensitivity C-reactive protein (Z = 2.108, P = 0.035) were higher in the intermediate coronary stenosis group, while less of them could reach anaerobic threshold (χ2 = 10.702, P = 0.001). The heard rate and respiratory exchange rate as anaerobic threshold decreased in the intermediate coronary stenosis group (Z > 2.156, P < 0.05). There was no significant difference in main cardiovascular events between the two groups within a year (P = 1.000).

Conclusion Cardiopulmonary capacity has been impaired in patients with intermediate coronary stenosis, who need to pay attention to the risk factors such as smoking, diabetes mellitus, hypertension and hyperlipidemia.

Key words: intermediate coronary stenosis, cardiopulmonary exercise test, heart rate, oxygen uptake, anaerobic threshold
