AIP and obesity disorder: Compared with participants with normal diastolic function, those with LVDD were more likely to be older than 55 years (p < 0.001), tended to have obesity (p = 0.045), had a higher risk of developing dyslipidemia (p = 0.041), and higher AIP and CRI-II (p < 0.05) levels while having similar low HDL-C and hypertriglyceridemia frequencies.
