Abstract-Although the profibrotic inflammatory substance galectin-3 predicts outcomes in the general population, the mechanisms responsible for this effect are uncertain. We aimed to determine whether circulating galectin-3 concentrations are associated with carotid femoral (aortic) pulse wave velocity and aortic reflective wave index (applanation tonometry and SphygmoCor software) in 966 randomly selected participants from a community sample. Galectin-3 concentrations were not independently associated with office (n=966) or 24-hour (n=661) systolic (P=0.88-0.92) or diastolic (P=0.65-0.94) blood pressure. In contrast, with adjustments for age, sex (in all participants), office or 24-hour mean arterial pressure (or systolic blood pressure and pulse pressure), pulse rate, body mass index, regular smoking, regular alcohol intake, total cholesterol concentrations, diabetes mellitus or an glycohemoglobin >6.1%, treatment for hypertension, and estimated glomerular filtration rate, galectin-3 was independently associated with aortic pulse wave velocity in all participants (partial r=0.15, P<0.0001) and reflective wave index in men (partial r=0.13, P<0.02). In 745 participants who had never received antihypertensive therapy, galectin-3 concentrations were similarly independently associated with pulse wave velocity in all participants (partial=0.16, P<0.0001) and reflective wave index in men (partial r=0.15, P<0.02). The blood pressureindependent relations between galectin-3 concentrations and aortic hemodynamics persisted with further adjustments for C-reactive protein concentrations (pulse wave velocity in all participants: partial r=0.14, P<0.0001; reflective wave index in men: partial r=0.12, P<0.05). In conclusion, despite a lack of independent association with brachial blood pressure, the profibrotic inflammatory substance galectin-3 may contribute toward adverse outcomes through an effect on aortic stiffness, an effect that cannot be attributed to general inflammatory changes.

Background Although obesity‐associated metabolic abnormalities (insulin resistance‐IR) may not play as marked a role in determining left ventricular (LV) diastolic dysfunction (DD) as hypertension, the impact of combinations of these risk factors on DD is unknown. Hypothesis We hypothesized that IR influences the impact of hypertension on DD. Methods In 704 randomly selected participants from a community sample with a high prevalence of hypertension (50.6%) and obesity (46.5%), we determined adiposity indices, IR from the homeostasis model (HOMA‐IR) and LV diastolic function using standard echocardiographic techniques. Results HOMA‐IR was independently associated with lateral wall e' and E/e' ( P < 0.05 to P < 0.005) as well as a diagnosis of DD ( P < 0.02). Importantly, however, an enhanced relationship between HOMA‐IR and E/e' in hypertensives (n = 356, partial r = 0.15, P < 0.005) as compared to normotensives (n = 348, partial r = 0.02 P = 0.75) was noted. Consequently, as compared to normotensives, with adjustments for confounders, hypertension was independently associated with DD only in those with the highest tertile of HOMA‐IR (odds ratio = 2.65, 95% confidence interval = 1.29‐5.42, P < 0.01), while in those with the lowest tertile of HOMA‐IR, hypertension failed to show a higher prevalence of DD ( P = 0.22). Conclusions Insulin resistance enhances the impact of hypertension on LV DD. Thus, DD is more likely to occur with the combination of hypertension and IR.

Nurse-recorded auscultatory blood pressure at a single visit predicts target organ changes as well as ambulatory blood pressure

Abstract: One or more, high-quality single visit nurse-recorded auscultatory BP measurements may be equally as effective as ambulatory BP in predicting target organ damage in a population sample of African ancestry.
