Abstract Background Conflicting information exists regarding the association between insulin resistance (IR) and left ventricular hypertrophy (LVH). We described the associations between obesity, fasting insulinemia, homeostasis model assessment of insulin resistance (HOMA-IR), and LVH in Black patients with essential hypertension. Methods A case–control study was conducted at the Centre Médical de Kinshasa (CMK), the Democratic Republic of the Congo, between January and December 2019. Cases and controls were hypertensive patients with and without LVH, respectively. The relationships between obesity indices, physical inactivity, glucose metabolism and lipid disorder parameters, and LVH were assessed using linear and logistic regression analyses in simple and univariate exploratory analyses, respectively. When differences were observed between LVH and independent variables, the effects of potential confounders were studied through the use of multiple linear regression and in conditional logistic regression in multivariate analyses. The coefficients of determination (R2), adjusted odds ratios (aORs), and their 95% confidence intervals (95% CIs) were calculated to determine associations between LVH and the independent variables. Results Eighty-eight LVH cases (52 men) were compared against 132 controls (81 men). Variation in left ventricular mass (LVM) could be predicted by the following variables: age (19%), duration of hypertension (31.3%), body mass index (BMI, 44.4%), waist circumference (WC, 42.5%), glycemia (20%), insulinemia (44.8%), and HOMA-IR (43.7%). Hypertension duration, BMI, insulinemia, and HOMA-IR explained 68.3% of LVM variability in the multiple linear regression analysis. In the logistic regression model, obesity increased the risk of LVH by threefold [aOR 2.8; 95% CI (1.06–7.4); p = 0.038], and IR increased the risk of LVH by eightfold [aOR 8.4; 95 (3.7–15.7); p < 0.001]. Conclusion Obesity and IR appear to be the primary predictors of LVH in Black sub-Saharan African hypertensive patients. The comprehensive management of cardiovascular risk factors should be emphasized, with particular attention paid to obesity and IR. A prospective population-based study of Black sub-Saharan individuals that includes the use of serial imaging remains essential to better understand subclinical LV deterioration over time and to confirm the role played by IR in Black sub-Saharan individuals with hypertension.

Aldosterone To Renin Ratio

AbstractThe diagnostic workup for primary aldosteronism includes a screening step using the aldosterone-to-renin ratio (ARR) and a confirmatory step based on dynamic testing of aldosterone secretion autonomy. International guidelines suggest that precise clinical and biochemical conditions may allow the bypassing of the confirmatory step, however, data which validate hormone thresholds defining such conditions are lacking. At our tertiary center, we retrospectively examined a cohort of 173 hypertensive patients screened for PA by the ARR, of whom 120 had positive screening and passed a saline infusion test (SIT) or a captopril challenge test (CCT). Fifty-nine had PA, including 34 Conn adenomas and 25 with idiopathic aldosteronism (IA). Using a threshold of 160 pmol/l, post-SIT plasma aldosterone concentration (PAC) identified PA with 86.4% sensitivity, 94.7% specificity, and a negative predictive value of 92.3%. Of those subjects with a high ARR and a PAC above 550 pmol/l, 93% had a positive SIT, while 100% of subjects with a high ARR, but a PAC under 240 pmol/l had a negative SIT. Our results thus validate the biochemical conditions defined in the French and US guidelines for bypassing the confirmatory step in the workup for PA diagnosis.

Arterial hypertension is frequently associated to glucose and lipid metabolism abnormalities. The purpose of this study was to determine if antioxidants (fruit extract) supplementation interfere with glucose and lipid metabolism in overweight hypertensive patients. A randomized clinical trial was conducted with 30 individuals, 23 hypertensive patients (group A) and 7 normotensive controls (group B). They were randomized to take 3 capsules of different fruits extract a day (blueberry, cranberry and pomegranate) or placebo for 4 weeks. This is a crossover study, which started with placebo changed to capsules and vice versa. Blood samples were collected after 12 hours fasting for biochemical tests (glucose, insulin, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides), anthropometric assessment (weight, height, and body mass index), systolic BP, diastolic BP and heart rate were evaluated at baseline, after 4, and 8 weeks. The comparisons between groups were held with the GLM repeated measures. Twenty three hypertensive patients (age 47 years, 14 females) and 7 normotensive controls (age 40 years, 7 females) were evaluated. BMI, blood pressure, heart and lipid profile did not differ between groups. HOMAir decreased significantly in both groups. See results in table 1. Values are expressed as medians (±SD) In these preliminary results a 4-weeks supplementation of antioxidants (fruit extract) improved insulin resistance in overweight hypertensive and normotensive subjects.
