Smoking is associated with an increased risk of coronary artery disease and other cardiovascular diseases. In this study, we analyzed the correlation between right ventricular strain and smoking-related parameters of 22 smoking volunteers and found that there was a positive statistical correlation between right ventricular radial strain, circumferential strain and smoking-related parameters respectively when the right ventricular ejection fraction was normal. Therefore, it is concluded that the right ventricle has a compensatory capacity for smoking on the heart for a certain period of time.
