Abstract Background: Type 2 diabetes mellitus (T2DM) insidiously affects the myocardium with subsequent cardiomyopathy, it also pathologically involves the microvascular bed of the kidney reflected by albuminuria. This study aimed to investigate the relation between albuminuria and subclinical left ventricular (LV) systolic dysfunction in asymptomatic normotensive patients with T2DM assessed by two-dimensional (2D) speckle tracking echocardiography.Methods and results Sixty normotensive patients with T2DM, within 5 years of initial diagnosis, receiving conventional oral antidiabetic medications were included and subdivided into 2 subgroups, each including thirty patients according to the presence of albuminuria, together with thirty healthy control subjects all underwent full echocardiographic examination including left ventricular (LV) regional and global longitudinal strain (GLS) measurements. Laboratory tests including serum creatinine, glycated hemoglobin (HbA1C) and albumin creatinine ratio (ACR) were withdrawn for the three groups. There was a significant reduction in average peak systolic LV global longitudinal strain (GLS) in patients with T2DM when compared to control group (-16.18 ± 2.78% versus -18.13 ± 2.86%, P<0.001), however there was no significant difference in average peak systolic LV GLS between both diabetic subgroups (-15.57 ± 2.77% in subgroup with albuminuria versus -16.79 ± 2.70% in subgroup without albuminuria, p=0.077). Moreover, there was a significant correlation between ACR and reduction of GLS in patients with T2DM and albuminuria (r =0.38, P=0.003). However, this correlation was absent in patients with T2DM without albuminuria (r=0.107, P=0.573). Conclusion: Patients with type 2 diabetes mellitus (T2DM) have subclinical LV systolic dysfunction despite normal ejection fraction through reduction of average peak systolic LV GLS that is correlated with albumin creatinine ratio in patients with T2DM and albuminuria.

Abstract Background Type 2 diabetes mellitus (T2DM) impairs cardiac function and is one of the risk factors for heart failure. However, the mechanism of cardiac impairment is not elucidated. Despa et al. reported that amylin has aggregation properties similar to amyloidogenic proteins and impairs cardiac function in T2DM patients with hyperamylinemia. In this hypothesis, T2DM-induced myocardial impairment is thought of as amylin-induced cardiac amyloidosis. The purpose of this study is to clarify whether a relative apical sparing pattern (RASP), which is well known as a typical pattern of cardiac amyloidosis, is common in T2DM. Methods We studied patients aged 75 years or over who underwent echocardiography from January 2018 to December 2020 in our clinic. We calculated the quantitative relative apical sparing (qRASP) as average apical-longitudinal strain (LS)/(average basal-LS + average mid-LS) in each patient. According to the validated threshold, a qRASP ≥1.0 was defined as an obvious RASP (oRASP). We compared the ratio of oRASP between patients with and without T2DM. Results We researched 506 patients, mean 81.8 years, 290 females, 133 with T2DM. The average age, atrial fibrillation rate, heart failure rate, and hypertension rate were similar in both groups. The ratio of ischemic heart disease was higher in the T2DM group. Echocardiography showed that the left atrial dimension (LAD), E/e', and left ventricular hypertrophy (LVH) ratio was higher in the T2DM group. Speckle tracking echocardiography revealed that global longitudinal strain (GLS) and qRASP of the T2DM group were higher than the non-DM group (GLS;-18.0% vs. −19.2%, p&lt;0.001. qRASP; 0.809 vs. 0.699, P&lt;0.001). Furthermore, the ratio of oRASP was significantly higher in the T2DM group (19.0% vs. 1.34%, p&lt;0.001). Multivariable logistic regression analysis showed T2DM was an independent predictor for oRASP. Conclusion This study revealed that the qRASP and the ratio of oRASP in the T2DM group were higher than non-DM group. This finding supports the hypothesis that T2DM related cardiomyopathy is a kind of cardiac amyloidosis caused by amylin. FUNDunding Acknowledgement Type of funding sources: None.

Background: Patients with heart failure (HF) with diabetes mellitus have distinct biomarker profiles compared with those without diabetes mellitus. SFRP5 (secreted frizzled-related protein 5) is an anti-inflammatory adipokine with an important suppressing role on the development of type 2 diabetes mellitus (T2DM). This study aimed to evaluate the prognostic value of SFRP5 in patients with HF with and without T2DM. Methods: The study included 833 consecutive patients with HF, 312 (37.5%) of whom had T2DM. Blood samples were collected at presentation, and SFRP5 levels were measured. The primary outcome was the composite end points of first occurrence of HF rehospitalization or all-cause mortality during follow-up. Results: During median follow-up of 2.1 years, 335 (40.2%) patients in the cohort experienced the composite primary outcome. After adjustment for multiple risk factors, each doubling of SFRP5 level was associated with a 21% decreased risk of primary outcomes in the overall study population ( P <0.001). Subgroup analyses showed that the association between level of SFPR5 and primary outcomes may be stronger in patients with T2DM (hazard ratio, 0.69 [95% CI, 0.61–0.79]) than in patients without T2DM (hazard ratio, 0.89 [95% CI, 0.79–1.01]; interaction P =0.006). Similar associations were observed when taking SFRP5 as a categorical variable. Addition of SFRP5 significantly improved discrimination and reclassification of the incident primary outcomes beyond clinical risk factors and N-terminal pro-B-type natriuretic peptide in all patients with HF and those with T2DM (all P <0.01). Conclusions: SFRP5 is an independent novel biomarker for risk stratification in HF, especially in HF with T2DM.
