[PMID: 37999892 DOI: 10.1007/s40618-023-02214-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 09/26/2023] [Indexed: 11/25/2023]
Abstract
BACKGROUND The incidence of preserved ejection fraction heart failure has significantly increased in persons with type 2 diabetes mellitus (T2DM). Left ventricular (LV) diastolic dysfunction is an early and important manifestation of preserved ejection fraction heart failure. The onset of heart failure in persons with diabetes is associated with diabetic neuropathy. However, the relationship among sudomotor function, which is an early manifestation of small fiber neuropathy, and LV diastolic function remains unclear. This study aimed to explore the association between sudomotor function and LV diastolic function in persons with T2DM. METHODS In total, 699 persons with T2DM were enrolled and divided into three groups according to electrochemical skin conductance (ESC) assessed using the SUDOSCAN device: "no dysfunction" group (NSF), "moderate dysfunction" group (MDF), and "severe dysfunction" group (SDF). LV diastolic function was assessed using Doppler echocardiography. To evaluate the relationship between ESC and echocardiographic parameters, Pearson's correlation analysis was performed. Additionally, logistic regression analysis was used to determine the association between LV diastolic function and ESC. A receiver operating characteristic (ROC) curve was constructed to evaluate the performance of sudomotor function indicators in detecting impaired cardiac diastolic function. RESULTS There were 301 persons (43.06%) in the NSF group, 232 (33.19%) in the MDF group, and 166 (23.75%) in the SDF group. Compared to the NSF group, the MDF and SDF groups had higher A and E/e' and lower e' values (all p < 0.05). Pearson's correlation analysis showed that A and E/e' were negatively associated with foot ESC (FESC) and hand ESC (HESC), whereas e' was positively associated with FESC and HESC (all p < 0.05). After adjusting for confounding factors, binary logistic regression analysis showed that ESC was independently associated with impaired LV diastolic function (p = 0.003). The area under the ROC curve values for FESC and HESC were 0.621 and 0.635, respectively (both p < 0.05). CONCLUSIONS Deteriorating sudomotor function was associated with reduced diastolic function indicators. ESC can be used as a biomarker for detecting LV diastolic impairment.

Risk Predictors of 3-Month and 1-Year Outcomes in Heart Failure Patients with Prior Ischemic Stroke. J Clin Med 2022; 11:jcm11195922. [PMID: 36233790 PMCID: PMC9573085 DOI: 10.3390/jcm11195922] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Revised: 10/01/2022] [Accepted: 10/02/2022] [Indexed: 11/20/2022] Open
Abstract
Background: Despite available therapy, mortality, and readmission rates within 60–90 days of discharge for patients hospitalized with heart failure (HF) are higher compared to the 1-year rates. This study sought to identify the risk factors of the combined endpoint of all-cause readmission or death among HF patients. Methods: Patients with a diagnosis of HF aged 65 or older were included in this prospective observational cohort study. The outcomes were estimated within 3-months and 1 year of discharge. Risk modeling was performed using a multivariable Cox regression analysis of HF patients older than 65 who had experienced ischemic stroke. Results: A total of 951 HF patients enrolled, of whom 340 (35.8%) had suffered a prior ischemic stroke. Significant predictors of increased 3-month all-cause readmission or death included DBP (p = 0.045); serum albumin (p = 0.025), TSH (p = 0.017); and discharge without ACE-inhibitor/ARB/ARNI (p = 0.025), β-blockers (p = 0.029), and antiplatelet drugs (p = 0.005). Heart rate (p = 0.040), laboratory parameters—including serum albumin (p = 0.003), CRP p = 0.028), and FT4 (p = 0.018)—and discharge without β-blockers (p = 0.003), were significant predictors of increased 1-year all-cause readmission and death. Conclusions: Without β-blockers, lower serum albumin and abnormal thyroid function increase the risks of readmission and death in elderly HF patients who have had an ischemic stroke by 3 months and 1 year after discharge. The other factors, such as being without ACEI/ARB and a high heart rate, only increase risks before 3 months or 1 year, not both.

Abstract
PURPOSE OF REVIEW This review provides a rationale for implementing carbohydrate restriction as a dietary therapy to improve biomarkers of cardiovascular health and suggests that this will require a paradigm shift away from what is currently promulgated as a 'heart-healthy' diet. RECENT FINDINGS Type 2 diabetes mellitus (T2DM), metabolic syndrome, and related co-morbidities are major risk factors for cardiovascular disease (CVD). Ideally, then, a diet intended to support cardiovascular health should be one that improves or reverses these underlying risk factors. Carbohydrate restriction is effective for this purpose as well as for favorably impacting atherogenic dyslipidemia. Recent consensus reports from select national organizations have endorsed low-carbohydrate diets for improving glycemia and cardiovascular risk. Reluctance among public health organizations and some clinicians to more widely promote this therapeutic nutritional approach is driven primarily by the increase in serum low-density lipoprotein cholesterol (LDL-C) observed in a proportion of individuals who adopt a low-carbohydrate diet. Here we explore the rationale for using carbohydrate restriction to improve cardiovascular health by way of favorably impacting T2DM and insulin resistance, and why this salutary effect outweighs the potential adverse effects of an increase in serum LDL-C. SUMMARY Carbohydrate restriction is a logical foundation for a dietary intervention intended to reduce CVD risk, particularly among individuals with T2DM or metabolic syndrome.

Abstract
This year, 2022, marks the 100th anniversary of the isolation of human insulin and its administration to patients suffering from diabetes mellitus (DM). Insulin exerts many effects on the human body, including the cardiac tissue. The pathways implicated include the PKB/Akt signaling pathway, the Janus kinase, and the mitogen-activated protein kinase pathway and lead to normal cardiac growth, vascular smooth muscle regulation, and cardiac contractility. This review aims to summarize the existing knowledge and provide new insights on insulin pathways of cardiac tissue, along with the role of left ventricular assist devices on insulin regulation and cardiac function.

Abstract
Background::
Short-chain fatty acids (SCFAs), generally acetate, propionate along with
butyrate, are aliphatic organic acids formed in the gut mucosa through bacterial fermentation of
mostly undigested nutritional carbohydrates, again to a minor degree by natural and dietary proteins,
such as mucous and shed epithelial cells.
Methods::
Many sources were used to collect information about Butyrate, such as Pub med, Google
Scholar, Pubmed, Scopus and other reliable sources.
:
Endogenous butyrate formation, absorption, and transportation by colon cells have now been well
acknowledged. Butyrate exerts its action features by way of appearing as a histone deacetylase inhibitor,
even signaling through a few protein receptors. Lately, butyrate has received special consideration
for its favorable result on intestinal equilibrium and also energy metabolism. There is a
growing interest in butyrate as its impact on epigenetic mechanisms will result in much more certain
and also efficacious healing techniques for the prevention and therapy of various diseases that
range from genetic conditions to other body disorders.
Conclusion::
With this assessment, we compile the existing information on the attributes of butyrate,
particularly its potential effects and also mechanisms involved in cancer, inflammation, diabetes
mellitus, neurological and cardiovascular disorder.

Abstract
The aim of the present study was to investigate the probable effects of metformin plus vildagliptin on the oxidative stress index (OSI) in patients with type II diabetes mellitus (T2DM). In this case–control study, 44 patients with T2DM on either metformin monotherapy (n = 24) or metformin plus vildagliptin (n = 20) were compared with healthy controls (n = 20). Anthropometric and biochemical variables including body mass index, blood pressure profile, cardiac indices, lipid profile, fasting blood glucose, fasting serum insulin, and glycemic indices were assessed. Besides, total oxidant status (TOS), total antioxidant status (TAS), and OSI were determined. Patients with T2DM have higher risk of cardiometabolic changes compared with the control (P = 0.0001). TAS was lower while TOS and OSI were higher in patients with T2DM, as compared with the healthy controls (P < 0.001). TAS, TOS, and OSI were better in patients with T2DM on metformin plus vildagliptin therapy as compared with metformin monotherapy (P < 0.05). Therefore, this study concluded that metformin plus vildagliptin therapy is more effective than metformin monotherapy in attenuation of OSI in patients with T2DM.

Abstract
Aim: Cardiac autonomic neuropathy (CAN) is a common and important chronic complication in diabetic patients. Heart failure resulting from cardiomyopathy is also a lethal complication in diabetic patients. However, data showing the exact association between CAN and heart failure in diabetic patients are relatively scarce. Therefore, our study aimed to determine the association between the parameters assessing CAN and heart function in diabetic patients.Method: The medical records of type 2 diabetic patients who underwent an autonomic function test with heart rate variability (HRV) and echocardiography were reviewed from January 2018 to December 2018. A total of 100 type 2 diabetic patients were included, and the association between the parameters assessing CAN and heart function was analysed.Results: Among the 100 analysed patients, 65 were diagnosed with CAN and 26 showed diastolic dysfunction. Moreover, 19 (73.1%) diabetic patients with diastolic dysfunction were complicated with CAN. The occurrence of diastolic dysfunction was higher in diabetic patients with CAN than in diabetic patients without CAN (29.2% vs 20.0%, p < 0.05), and the occurrence of CAN was higher in diabetic patients with diastolic dysfunction than in patients without diastolic dysfunction (73.1% vs 62.2%, p < 0.05). However, there were no significant associations between HRV parameters and heart function.Conclusion: We demonstrated that diastolic dysfunction is more common in diabetic patients complicated with CAN than in diabetic patients without CAN, although several diabetic patients without diastolic dysfunction are also diagnosed with CAN. Moreover, further studies about the long-term serial monitoring of heart function according to the progression of CAN are required to confirm the exact association between CAN and heart function.

Abstract
Aim. To study the effect of hyperglycemia on the total surface charge of the erythrocyte membrane (SCEM) in patients with metabolic syndrome (MS).Material and methods. 112 MS patients were examined (45 men and 67 women) (mean age 61.4±7.2 years, average MS duration 8.7±5.2 years). The level of SCEM was determined by adsorption of a positive cationic dye (cationic blue O) on the surface of the plasma membrane of erythrocytes to completely neutralize their negative charge, followed by photometry of the solution and calculation of the number of charges on the cell surface of erythrocytes.Results. In the main group of patients with MS, abdominal obesity was observed in 100% of patients, arterial hypertension – in 73%, hyperglycemia – in 75%, dyslipidemia – in 80%. The level of glycated hemoglobin (HbA1c) was determined in all patients with MS, which was 7.3±1.9%. Patients with MS were conditionally divided according to the level of HbA1c into 2 groups (group 1 – HbA1c from 6.6 to 7.8%, group 2 – more than 7.8%). In MS patients with hyperglycemia, the SCEM values were significantly lower than in the group of patients without hyperglycemia (1.58±0.05×107 and 1.64±0.03×107, respectively; p=0.001)., Significant negative correlations between SCEM and the fasting blood glucose level, hyperglycemia duration, HbA1c level were found in patients with MS.Conclusion. SCEM indices reliably depended on the presence, severity and duration of hyperglycemia, which indicated the effect of impaired carbohydrate metabolism on the state of electric charge of erythrocyte membranes and, therefore, on the mechanisms of microvascular blood flow, thereby contributing to the development of vascular changes in patients with MS.
