The Effects of eGFR Change on CVD, Renal, and Mortality Outcomes in a Hypertensive Cohort Treated With 3 Different Antihypertensive Medications.

ABSTRACT: BACKGROUND:Impaired renal function is a risk factor for cardiovascular disease, end-stage renal disease (ESRD), and mortality. The impact of short-term renal function decline on outcomes is less well studied. The association of antihypertensive medications with the impact of short-term estimated glomerular filtration rate (eGFR) decline is not known. METHODS:We examined 20,207 hypertensive participants with baseline and 2-year creatinine levels from which eGFR changes were estimated. The associations between eGFR change with incident coronary heart disease (CHD), stroke, heart failure (HF), all-cause mortality, and ESRD during 2.9 years of in-trial follow up, and with mortality during in-trial and post-trial follow-up (7.6 years), were studied. Results were assessed by primary hypertension (HTN) treatment (chlorthalidone, lisinopril, and amlodipine) and adjusted for baseline eGFR levels. RESULTS:In the short run, an eGFR decline below the cohort median (-1.28 ml/minute/1.73 m2/2 years) vs. above the median, or a 5 ml/min/1.73 m2/year decline vs. no decline, was associated with significant hazard risk for CHD (1.06-1.28), HF (1.24-1.91), ESRD (2.84-6.01), and mortality (1.08-1.19), but not with stroke risk. In the long term, there was a significant association with mortality (1.11-1.34). Interaction terms for outcomes by antihypertensive treatments were not statistically significant except for ESRD between amlodipine vs. chlorthalidone (hazard ratio: 3.17 [2.59, 3.88] vs. 2.41 [1.98, 2.97]; P interaction = 0.005) for a 5 ml/min/1.73 m2/year eGFR decline. CONCLUSION:Decline in eGFR over 2 years is associated with increased risk of clinical outcomes beyond the effects of baseline eGFR. These risks were the same irrespective of the primary medication used to treat HTN.

Project description:Evidence relating the rate of change in renal function, measured as eGFR, after antihypertensive treatment in elderly patients to clinical outcome is sparse. This study characterized the rate of change in eGFR after commencement of antihypertensive treatment in an elderly population, the factors associated with eGFR rate change, and the rate's association with all-cause and cardiovascular mortality.Data from the Second Australian National Blood Pressure study were used, where 6083 hypertensive participants aged ?65 years were enrolled during 1995-1997 and followed for a median of 4.1 years (in-trial). Following the Second Australian National Blood Pressure study, participants were followed-up for a further median 6.9 years (post-trial). The annual rate of change in the eGFR was calculated in 4940 participants using creatinine measurements during the in-trial period and classified into quintiles (Q) on the basis of the following eGFR changes: rapid decline (Q1), decline (Q2), stable (Q3), increase (Q4), and rapid increase (Q5).A rapid decline in eGFR in comparison with those with stable eGFRs during the in-trial period was associated with older age, living in a rural area, wider pulse pressure at baseline, receiving diuretic-based therapy, taking multiple antihypertensive drugs, and having blood pressure <140/90 mmHg during the study. However, a rapid increase in eGFR was observed in younger women and those with a higher cholesterol level. After adjustment for baseline and in-trial covariates, Cox-proportional hazard models showed a significantly greater risk for both all-cause (hazard ratio, 1.28; 95% confidence interval, 1.09 to 1.52; P=0.003) and cardiovascular (hazard ratio, 1.40; 95% confidence interval, 1.11 to 1.76; P=0.004) mortality in the rapid decline group compared with the stable group over a median of 7.2 years after the last eGFR measure. No significant association with mortality was observed for a rapid increase in eGFR.In elderly persons with treated hypertension, a rapid decline in eGFR is associated with a higher risk of mortality.

Project description:Quality and quantity of home blood pressure (BP) control are important for optimizing hypertensive treatment. The prevalence and associated clinical characteristics of the different home blood pressure phenotypes in treated hypertensive patients were not elucidated. This study was conducted in Siriraj Hospital, Thailand from 2019 to 2020. We included treated hypertensive patients with ≥1 antihypertensive drug and had self-home BP measurement data. Both traditional (office BP < 140/90 mmHg and home BP < 130/80 mmHg) and new BP targets (office and home BP < 130/80 mmHg) were used for the classification of BP phenotypes. Home BP phenotypes consisted of controlled hypertension (all home BPs achieved home BP targets), isolated uncontrolled morning hypertension (MoHT) (only morning BP was above home BP targets), isolated uncontrolled evening hypertension (EHT) (only evening BP was above home BP targets), and combined morning-evening uncontrolled hypertension (MoEHT) (all home BPs were above home BP targets). Our study included 1,406 patients. The total mean age was 62.94 ± 13.97 years. There were 39.40% men. The prevalence of each home BP phenotype (by traditional BP target) was 55.76%, 12.66%, 7.40%, and 24.18% in controlled (home) hypertension, MoHT, EHT, and MoEHT, respectively. Classical BP control status was 35.21% well-controlled hypertension, 30.01% white-coat uncontrolled hypertension, 9.74% masked uncontrolled hypertension, and 25.04% sustained uncontrolled hypertension. The multivariable analysis showed the significantly associated factor of MoHT was the presence of previous cardiovascular disease (adjusted OR 5.54, 95% CI (2.02-15.22); p value = 0.001). Taking once-daily long-acting antihypertensive drugs in the morning were significantly associated with both EHT (adjusted OR 0.20, 95% CI (0.05-0.82); p value = 0.025) and MoEHT (adjusted OR 0.20, 95% CI (0.04-1.00); p value = 0.049). These results were consistent in groups classified by new home BP target <130/80 mmHg.

Project description:BackgroundTo further inform benefits and risks of medications on physical function in aging populations, we have evaluated the associations of antihypertensive (antiHTN) class and number used with skeletal muscle function, mobility, sedentary time, and symptoms in older persons.MethodsUsing baseline data from the Lifestyle Interventions and Independence in Elder (LIFE) study (N = 1567, mean age 78.9 years) and multivariable models, we evaluated cross-sectional associations of antiHTN class and number used with physical measures and symptom questionnaires. AntiHTN class included diuretics, angiotensin converting enzyme inhibitors (ACEi), angiotensin receptor blockers (ARB), calcium channel blockers (CCB), and beta blockers (BB). Physical measures included respiratory muscle weakness (maximal inspiratory pressure), grip weakness (dynamometer), impaired lower extremity proximal muscle strength (chair stands), impaired balance (three-stage test), slow gait (400 m walk), mobility impairment (Short Physical Performance Battery), and high sedentary time (accelerometry). Symptoms included dyspnea and fatigue. Covariates included clinical characteristics and non-antiHTNs.ResultsUse of any antiHTN was highly prevalent (n = 1248 [79.6%]). In the antiHTN subgroup, each antiHTN class was well represented (ranging 36.6%-62.7%) and included use of three or more antiHTNs (32.0%). In adjusted models, the only statistically significant associations were use of BB and three or more antiHTNs with high sedentary time: odds ratios (95% confidence intervals) 1.44 (1.12, 1.85) and 1.52 (1.04, 2.23), respectively.ConclusionUse of BB and three or more antiHTNs yielded 44% and 52% increased odds of accelerometry-defined high sedentary time, respectively. Notably, high sedentary time is a risk factor for adverse health outcomes. Thus, future work should evaluate whether high sedentary time mitigates benefits or increases risks, regarding antiHTN use in aging populations.
