Age-stratified association of blood pressure with albuminuria and left ventricular hypertrophy in patients with hypertension and diabetes mellitus

Purpose We investigated associations of blood pressure (BP) with albuminuria and left ventricular hypertrophy (LVH) in young, middle and older aged patients with hypertension and/or diabetes mellitus. Materials & Methods Study participants were treated patients with hypertension or diabetes, enrolled in a China nationwide registry. The 2510 patients were classified into young (<45 years, n = 345), middle (45–64 years, n = 1383) and older (≥65 years, n = 782) age groups. Clinic BP was measured three times consecutively on each of the two clinic visits. These six readings were averaged for analyses. Albuminuria was defined as a urinary albumin-to-creatinine ratio of ≥30 mg/g. LVH was assessed by the electrocardiogram (ECG) Cornell product and voltage methods. Results The prevalence of albuminuria and ECG-LVH was 17.8 and 6.5%, respectively. Mean (±SD) systolic/diastolic BP was 132.0 ± 16.5/85.2 ± 11.9 mmHg, 136.8 ± 17.9/81.7 ± 11.2 mmHg, and 139.8 ± 16.7/75.8 ± 10.4 mmHg in the young, middle and older age groups. In the young age group, the prevalence of albuminuria increased from 8.8% in systolic/diastolic BP <120/80 mmHg to 14.6, 16.0% and 16.5% in 120–129/80–84, 130–139/85–89 and ≥140/90 mmHg, respectively. The corresponding values were 8.9, 7.0, 18.1 and 22.2%, respectively, in the middle age group, and 21.2, 15.5, 16.4 and 24.4%, respectively, in the older age group. Adjusted analyses confirmed the J-shaped relation between BP and albuminuria in the older but not young age group. The prevalence of ECG-LVH was significantly (p for trend ≤0.04) higher with increasing BP similarly in all age groups. Conclusions The association between BP and organ damage seems to differ in young, middle and older aged patients for albuminuria but not ECG-LVH

Prognostic Impact of Renal Dysfunction Does Not Differ According to the Clinical Profiles of Patients: Insight from the Acute Decompensated Heart Failure Syndromes (ATTEND) Registry

<div><p>Background</p><p>Renal dysfunction associated with acute decompensated heart failure (ADHF) is associated with impaired outcomes. Its mechanism is attributed to renal arterial hypoperfusion or venous congestion, but its prognostic impact based on each of these clinical profiles requires elucidation.</p><p>Methods and Results</p><p>ADHF syndromes registry subjects were evaluated (N = 4,321). Logistic regression modeling calculated adjusted odds ratios (OR) for in-hospital mortality for patients with and without renal dysfunction. Renal dysfunction risk was calculated for subgroups with hypoperfusion-dominant (eg. cold extremities, a low mean blood pressure or a low proportional pulse pressure) or congestion-dominant clinical profiles (eg. peripheral edema, jugular venous distension, or elevated brain natriuretic peptide) to evaluate renal dysfunction's prognostic impact in the context of the two underlying mechanisms. On admission, 2,150 (49.8%) patients aged 73.3±13.6 years had renal dysfunction. Compared with patients without renal dysfunction, those with renal dysfunction were older and had dominant ischemic etiology jugular venous distension, more frequent cold extremities, and higher brain natriuretic peptide levels. Renal dysfunction was associated with in-hospital mortality (OR 2.36; 95% confidence interval 1.75–3.18, p<0.001), and the prognostic impact of renal dysfunction was similar in subgroup of patients with hypoperfusion- or congestion-dominant clinical profiles (p-value for the interaction ranged from 0.104–0.924, and was always >0.05).</p><p>Conclusions</p><p>Baseline renal dysfunction was significantly associated with in-hospital mortality in ADHF patients. The prognostic impact of renal dysfunction was the same, regardless of its underlying etiologic mechanism.</p></div

Association between dyslipidemia and antihypertensive and antidiabetic treatments in a China multicenter study

Abstract Dyslipidemia is an emerging disease in China, especially in the presence of hypertension and diabetes mellitus. We investigated the association of dyslipidemia with the use of antihypertensive and antidiabetic agents. The study participants (n = 2423) were hypertensive and diabetic patients enrolled in a China nationwide registry. Serum mean ± (SD, except for serum triglycerides, median [interquatile range]) concentrations were 1.38 (0.97‐2.02) mmol/L, 4.85 ± 1.12 mmol/L, 1.30 ± 0.36 mmol/L, and 2.89 ± 0.92 mmol/L for triglycerides and total, high‐density lipoprotein (HDL), and low‐density lipoprotein (LDL) cholesterol, respectively. The prevalence of dyslipidemia was 18.9%, 13.5%, 16.6%, and 37.7% for hypertriglyceridemia (serum triglycerides ≥2.3 mmol/L), hypercholesterolemia (total cholesterol ≥6.2 mmol/L or LDL cholesterol ≥4.1 mmol/L), low HDL cholesterol (HDL cholesterol <1.0 mmol/L), and any of the three lipid disorders, respectively. Treated (n = 1647), compared with untreated hypertensive patients (n = 303), had a significantly (P ≤ .0006) lower serum total, LDL, and HDL cholesterol, but similar serum triglycerides (P = .20). Treated (n = 1325), compared with untreated diabetic patients (n = 238), had a significantly (P ≤ .004) lower serum triglycerides, and total and LDL cholesterol, but similar serum HDL cholesterol (P = .81). After adjustment, the odds ratios (OR) were significant for hypercholesterolemia (OR 0.76, 95% confidence interval [CI] 0.58‐0.997, P = .048) and low HDL cholesterol (OR 1.56, CI 1.19‐2.03, P = .001) in treated versus untreated hypertension, and for low HDL cholesterol (OR 1.50, CI 1.18‐1.89, P = .0008) in treated versus untreated diabetes. In conclusion, the prevalence of dyslipidemia differed between treated and untreated hypertension and diabetes

Alcohol intake and dyslipidemia in male patients with hypertension and diabetes enrolled in a China multicenter registry

Abstract Alcohol consumption is a proven risk factor of dyslipidemia. In the present analysis, we investigated the association of alcohol intake with dyslipidemia, an emerging epidemic in China, in male patients with hypertension and diabetes mellitus. Our study participants were from a nationwide registry (n = 1181). A questionnaire was administered to collect information on alcohol intake. Dyslipidemia was defined as an elevated concentration of serum triglycerides (≥2.3 mmol/L), total (≥6.2 mmol/L) or low‐density lipoprotein (LDL) cholesterol (≥4.1 mmol/L), or a reduced high‐density lipoprotein (HDL) cholesterol (< 1.0 mmol/L). Serum concentrations of triglycerides (1.60 mmol/L) and total (4.93 mmol/L) and LDL cholesterol (2.95 mmol/L) were highest with current usual drinking, with a significant P value for trend from never (n = 679) to ever (n = 107) and to rare (n = 187) and usual drinkers (n = 208, P ≤ .002). Serum HDL cholesterol (1.13 mmol/L) was lowest in ever drinkers, with a nonsignificant P value for trend (P = .22). The prevalence was highest in usual drinkers for hypertriglyceridemia (27.4%) and total (12.5%) and LDL hypercholesterolemia (8.7%), and in ever drinkers for low HDL cholesterol (34.6%). The P value for trend was significant for hypertriglyceridemia and total hypercholesterolemia (P ≤ .01), but not for LDL hypercholesterolemia or low HDL cholesterol (P ≥ .26). The between‐province ecological analysis showed that the proportion of usual drinking was significantly associated with the prevalence of any dyslipidemia across 10 China provinces (r = .42, P < .0001). In conclusion, alcohol drinkers showed a worse lipid profile in patients with hypertension and diabetes mellitus. Usual drinking ecologically explained the between‐province variation in the prevalence of dyslipidemia
