ABSTRACT

Objective:

To explore the correlation between body mass index(BMI)and coronary flow reserve(CFR)in patients with chest pain and no obstructive coronary artery disease(NOCA).

Methods:

This study was a single-center retrospective cross-sectional study. Sixty-six patients with chest pain and NOCA on coronary angiography who underwent PET/CT quantitative myocardial blood flow measurements at TEDA International Cardiovascular Hospital were retrospectively analyzed from August 2018 to October 2019. Pearson correlation analysis and linear regression analysis were used to explore the correlation between BMI and CFR. Patients were divided into 2 groups according to CFR coronary microvascular dysfunction(CMD)group(CFR<2.5)and control group(CFR≥2.5). Logistic regression analysis was applied to analyze the association of BMI with CMD.

Results:

The proportions of female, obesity, and overweight plus obesity in CMD group were higher than those in control group( P<0.05). The levels of BMI and low density lipoprotein-cholesterol(LDL-C)were higher in CMD group compared with control group( P<0.05). Pearson correlation analysis showed that CFR was linearly correlated with BMI( r=-0.45, P<0.01), which still existed after adjusted by confounding factors using linear regression model( r=-0.371, P<0.01). Logistic regression analysis showed that BMI was dependently associated with CMD after adjusted by gender, age, hypertension, diabetic mellitus, and LDL-C. The OR value of CMD was 4.46(95% CI 1.47-13.55, P<0.01)with BMI increased by 5 kg/m 2.

Conclusion:

In patients with chest pain and NOCA, higher BMI is an independent risk factor of CMD.
