ABSTRACT
Objective:
To evaluate the independent prognostic value of minute ventilation/carbon dioxide production slope (VE/Vco 2 slope)on heart failure after acute myocardial infarction.Methods:
131 patients with acute myocardial infarction (AMI) treated in the cardiology department of China-Japan Friendship Hospital from September 2018 to September 2019 were collected and followed up 3 months after discharge. They were divided into heart failure (HF) group and non-heart failure (NHF) group. All the patients underwent cardiopulmonary exercise test (CPET) before discharge.Results:
Three months after discharge, the VE/Vco 2 slope was higher in HF group than in NHF group (36.7±3.8 vs 29.7±4.0, P=0.014). The best VE/Vco 2 slope cutoff for the prediction of heart failure after 3 month was 33.05 with a sensitivity of 81.4% and a specificity of 80.6% [area under curve (AUC) was 0.844, P<0.001]. VE /Vco 2 slope level was an independent predictor of heart failure in patients with acute myocardial infarction after discharge ( OR=1.245, 95% CI 1.021-1.366, P=0.019). Other independent indicators related to heart failure included N-terminal pro-B type natriuretic peptid (NT-proBNP) level ( OR=1.283, 95% CI 1.019-1.399, P=0.033).Conclusions:
VE/Vco 2 slope yielded strong, independent predictive value for heart failure at 3 month after discharge to AMI patients.
