Plant-based diets are a growing trend, including among athletes. This study compares the differences in physical performance and heart morphology and function between vegan and omnivorous amateur runners. A study group and a matched control group were recruited comprising N = 30 participants each. Eight members of the study group were excluded, leaving N = 22 participants. Members of both groups were of similar age and trained with similar frequency and intensity. Vegans displayed a higher VO2max (54.08 vs. 50.10 mL/kg/min, p < 0.05), which correlated positively with carbohydrate intake (ρ = 0.52) and negatively with MUFA (monounsaturated fatty acids) intake (ρ = −0.43). The vegans presented a more eccentric form of remodelling with greater left ventricular end diastolic diameter (LVEDd, 2.93 vs. 2.81 cm/m2, p = 0.04) and a lower relative wall thickness (RWT, 0.39 vs. 0.42, p = 0.04) and left ventricular mass (LVM, 190 vs. 210 g, p = 0.01). The left ventricular mass index (LVMI) was similar (108 vs. 115 g/m2, p = NS). Longitudinal strain was higher in the vegan group (−20.5 vs. −19.6%, p = 0.04), suggesting better systolic function. Higher E-wave velocities (87 vs. 78 cm/s, p = 0.001) and E/e′ ratios (6.32 vs. 5.6, p = 0.03) may suggest better diastolic function in the vegan group. The results demonstrate that following a plant-based diet does not impair amateur athletes’ performance and influences both morphological and functional heart remodelling. The lower RWT and better LV systolic and diastolic function are most likely positive echocardiographic findings.

Background: Cardiovascular complications account for the highest mortality in diabetic patients, mainly due to coronary artery disease and congestive heart failure. Left ventricular hypertrophy (LVH) is an ominous prognostic sign and an independent risk factor for cardiac events which is frequently present in patients living with diabetes. Aims and Objectives: The aim of the study was to evaluate the LV mass and function in normotensive diabetes patients without antihypertensive medication. Materials and Methods: 100 normotensive diabetic patients were in study group and 100 control patients were studied. Hypertension and other known causes of LVH were excluded from the study. Data were analyzed using proper statistical method. Results: Left ventricular mass index (LVMI) is significantly higher in diabetic patients as compared to control population (P<0.001). It was also observed that the means of the left ventricular posterior wall thickness, interventricular septal thickness, and the left ventricular internal diameter during diastole (in all cases P<0.001) were statistically significantly high in diabetic patients in comparison to healthy control subjects. We have found that a significant systolic dysfunction in diabetic group and diastolic dysfunction also very common in diabetic group than the control group. The LVMI also increased in patients who have longer duration of diabetes and poor glycemic control. Conclusion: LVM is significantly higher in patients of type 2 diabetic without having hypertension, albuminuria, and apparent ischemic heart disease as compared to healthy controls. LVM in diabetic patients increases with duration of diabetes and is positively correlated with HbA1c and blood sugar level.

Introduction: Sodium-glucose Cotransporter-2 (SGLT-2) inhibitors are drugs with profound interest because of their beneficial effect on multiple organ systems, including the cardiovascular and renal systems. Their interplay with these systems could prove beneficial in managing complex conditions like heart failure with preserved ejection fraction. We sought to compare cardiac diastolic function in patients on SGLT-2 inhibitors with those on metformin. Methods: Data were collected retrospectively after approval from our institutional review board. The study group included patients on SGLT-2 inhibitors (n=75), and the control group had patients on metformin (n=82), primarily for diabetes mellitus. Patients with ejection fraction less than 50% were excluded from the study. Data collected included age, systolic blood pressure (SBP), left ventricular (LV) ejection fraction, LV and left atrial dimensions, and diastolic parameters. Mean values, along with standard deviation, were calculated. Multivariate regression analysis for diastolic function was performed while adjusting for confounders, including age, body mass index, and SBP. Results: Study group showed better diastolic function as evidenced by significantly higher e’ medial (6.8 v/s 6.16 cm/s; p = 0.03) and e’ lateral (9.8 v/s 7.9 cm/s; p=0.008) when compared to the control group. E/e’, a marker of pulmonary capillary wedge pressure, was lower in the study group (12.87 v/s 14.36; p=0.08); however, it did not reach statistical significance. LA volume index was significantly lower in the study group, suggestive of favorable hemodynamic status (26.5 v/s 29.6 mL/m 2 ; p=0.03). SBP was significantly lower in the study group (127 v/s 135 mm Hg; p=0.01). Multivariate regression model demonstrated SBP as a significant confounder that contributed to e’ (average) difference between the two groups. Conclusions: SGLT-2 inhibitors favored better diastolic measurements when compared with metformin alone. The mechanism may be attributed to its BP-lowering effect. A larger prospective study is required to determine the role of SGLT-2 inhibitors.
