Female gender was associated with significantly higher left ventricular diastolic elastance during 25 W exercise compared to men (0.20 vs 0.15, p=0.009) among patients with type 2 diabetes.

Does left ventricular diastolic elastance during exercise differ between female and male patients with type 2 diabetes?
Female patients with type 2 diabetes exhibit greater left ventricular stiffness during exercise compared to male patients, highlighting a potential gender-specific mechanism for exercise intolerance.
Absolute Event Rate: 0.2% vs 0.15%
p-value: p=0.009
BACKGROUND: Because the ratio of mitral inflow and annular velocity to stroke volume has been reported as an index of diastolic elastance (Ed), the hypothesis tested in the present study was that Ed during exercise would be more abnormal in female than in male patients with type 2 diabetes. METHODS AND RESULTS: Ed was measured at rest and during graded supine bicycle exercise (25W, 3-min increments) in 53 patients (27 males, mean age 53+/-14 years) with type 2 diabetes and 53 age- and gender-matched controls. The patients with diabetes were divided into 2 groups by gender. Ed was not significantly different at rest between men and women, but was significantly higher during exercise in women than in men (25 W, 0.15+/-0.04 vs 0.20+/-0.07, p=0.009; 50 W, 0.16+/-0.05 vs 0.21+/-0.08, p=0.0175). CONCLUSION: Left ventricular (LV) diastolic elastance is abnormal during exercise, but not at rest, in patients with diabetes without overt heart disease. Female gender was associated with increased LV stiffness during exercise among patients with type 2 diabetes.
Ha et al. (Tue,) conducted a observational in Type 2 diabetes mellitus (n=106). Female gender vs. Male gender was evaluated on Left ventricular diastolic elastance (Ed) during 25 W exercise (p=0.009). Female gender was associated with significantly higher left ventricular diastolic elastance during 25 W exercise compared to men (0.20 vs 0.15, p=0.009) among patients with type 2 diabetes.
