Effect of intravenous antihypertensives on outcomes of severe hypertension in hospitalized patients without acute target organ damage.

ABSTRACT:

Background

Treatment of severe inpatient hypertension (HTN) that develops during hospitalization is not informed by guidelines. Intravenous (i.v.) antihypertensives are used to manage severe HTN even in the absence of acute target organ damage; however they may result in unpredictable blood pressure (BP) reduction and cardiovascular events. Our goal was to assess the association between i.v. antihypertensives and clinical outcomes in this population.

Methods

This is a multihospital retrospective study of adults admitted for reasons other than HTN who develop severe HTN during hospitalization without acute target end organ damage. We defined severe HTN as BP elevation of systolic >180 or diastolic >110 mmHg. Treatment was defined as receiving i.v. antihypertensives within 3 h of BP elevation. We used overlap propensity score weighted Cox models to study the association between treatment and clinical outcomes during index hospitalization.

Results

Of 224 265 unique, nonintensive care unit hospitalizations, 20 383 (9%) developed severe HTN, of which 5% received i.v. antihypertensives and 79% were untreated within 3 h of severe BP elevation. In the overlap propensity weighted population, patients who received i.v. antihypertensives were more likely to develop myocardial injury (5.9% in treated versus 3.6% in untreated; hazard ratio [HR]: 1.6 [1.13, 2.24]). Treatment was not associated with increased risk of stroke (HR: 0.7 [0.3, 1.62]), acute kidney injury (HR: 0.97 [0.81, 1.17]), or death (HR: 0.86 [0.49, 1.51]).

Conclusions

Intravenous antihypertensives were associated with increased risk of myocardial injury in patients who develop severe HTN during hospitalization. These results suggest that i.v. antihypertensives should be used with caution in patients without acute target organ damage.

Project description:BackgroundHypertension-mediated organ damage (HMOD), comprising structural and functional changes in arteries or end organs, is a marker of cardiovascular (CV) disease. However, there are limited data on evaluation of risk of CV disease regarding HMOD, especially in Asians. We sought to investigate the association between CV events and HMOD, and we tried to determine the most important diagnostic marker among the component of HMOD for prevention of mortality and CV events in treated Korean hypertensive patients.MethodsFrom January 2008 to December 2010, a total of 35,000 hypertensive Vietnamese War veterans who consecutively visited our hospital for medical check-up were reviewed, and 6,158 patients without established CV disease were enrolled. The patients were divided into two groups as follows: HMOD group (n = 766) and non-HMOD group (n = 5,392). The primary outcome was all-cause death.ResultsMedian age was 63.3 years (interquartile range [IQR], 61.4-65.4), and median follow-up was 6.6 years (IQR, 5.9-7.2). Patients with old age, diabetes, and chronic kidney disease were more prevalent in the HMOD group than in the non-HMOD group (all P < 0.05). The lipid profiles were not significantly different between the two groups. Nephropathy was the most prevalent (54.7%) organ damage in the HMOD group. The 6-year incidence of all-cause death was higher in the HMOD group than in the non-HMOD group (22.5% vs. 9.0%; adjusted hazard ratio [HR], 1.42; 95% confidence interval [CI], 1.01-2.00; P = 0.04). The incidence of cardiac death, ischemic heart disease, and ischemic and hemorrhagic stroke were also significantly higher in the HMOD group than in the non-HMOD group (P < 0.05, respectively). In multivariate analysis, proteinuria (adjusted HR, 2.21; 95% CI, 1.52-3.20; P < 0.001) was the most powerful independent risk factor to predict all-cause death among components of HMOD. As the degree of proteinuria increased, the rate of all-cause death also increased (long-rank P < 0.001).ConclusionHMOD was associated with increased risk of mortality and CV events. Proteinuria was the most powerful independent risk factor for all-cause death, and the degree of proteinuria and mortality rate were proportional. Our data suggest that monitoring of the proteinuria is important to predict long-term CV events in hypertensive patients.

Project description:BackgroundBlood pressure (BP) elevations are commonly treated in hospitalized patients; however, treatment is not guideline directed. Our objective was to assess BP response to commonly prescribed antihypertensives after the development of severe inpatient hypertension (HTN).MethodsThis is a cohort study of adults, excluding intensive care unit patients, within a single healthcare system admitted for reasons other than HTN who developed severe HTN (systolic BP>180 or diastolic BP >110 mmHg at least 1 hour after admission). We identified the most commonly administered antihypertensives given within 6 hours of severe HTN (given to >10% of treated patients). We studied the association of treatment with each antihypertensive vs. no treatment on BP change in the 6 hours following severe HTN development using mixed-effects model after adjusting for demographics and clinical characteristics.ResultsAmong 23,147 patients who developed severe HTN, 9,166 received antihypertensive treatment. The most common antihypertensives given were oral metoprolol (n = 1991), oral amlodipine (n = 1812), oral carvedilol (n = 1116), IV hydralazine (n = 1069) and oral hydralazine (n = 953). In the fully adjusted model, treatment with IV hydralazine led to 13 [-15.9, -10.1], 18 [-22.2, -14] and 11 [-14.1, -8.3] mmHg lower MAP, SBP, and DBP in the 6 hours following severe HTN development compared to no treatment. Treatment with oral hydralazine and oral carvedilol also resulted in significantly lower BPs in the 6 hours following severe HTN development (6 [-9.1, -2.1 and -7 [-9.1, -4.2] lower MAP, respectively) compared to no treatment. Receiving metoprolol and amlodipine did not result in a drop in BP compared to no treatment.ConclusionAmong commonly used antihypertensives, IV hydralazine resulted in the most significant drop in BP following severe HTN, while metoprolol and amlodipine did not lower BP. Further research to assess the effect of treatment on clinical outcomes and if needed which antihypertensives to administer are necessary.
