  • Impact of alcohol habits and smoking on the risk of new-onset atrial fibrillation in hypertensive patients with ECG left ventricular hypertrophy: The LIFE Study
  • 2011
  • Ingår i: Blood pressure. - 1651-1999.
  • Tidskriftsartikel (refereegranskat)abstract
    • Abstract Background. The incidence of new-onset atrial fibrillation (AF) is increased by uncontrolled hypertension, and antihypertensive treatment reduces new-onset AF. However, it is unclear whether alcohol intake and smoking influence the risk of new-onset AF during antihypertensive treatment. Methods. In the Losartan Intervention For Endpoint reduction in Hypertension (LIFE) study, a double-blinded, randomized, parallel-group study, 9193 hypertensive patients with electrocardiogram (ECG)-documented left ventricular hypertrophy (LVH), randomized to once-daily losartan- or atenolol-based antihypertensive therapy were followed for a mean of 4.8 years. At baseline, 8831 patients (54% women, mean age 67 years, mean blood pressure 174/98 mmHg after placebo run-in) had neither a history of AF nor AF on ECG, and they were thus at risk of developing this condition during the study. Results. New-onset AF occurred in 353 (4%) patients. Univariate Cox analyses showed that intake of alcohol > 10 units/week compared with less or no alcohol intake predicted new-onset AF (Hazard ratio, HR = 1.60 [95% CI 1.02-2.51], p = 0.043). Multivariate Cox regression analysis showed that intake of alcohol > 10 units/week predicted new-onset AF (p = 0.010) independently of most other univariate predictors, except when also baseline serum cholesterol, serum potassium and urinary albumin/creatinine ratio were included in the model (HR = 1.60 [95% CI 0.94-2.72], p = 0.081). Impact of smoking was not significant in Cox univariate or multivariate analyses, and there were no significant interactions between high alcohol intake and either smoking or gender on the risk of getting AF. Conclusions. Up to 10 drinks of alcohol per week appears to be safe with respect to the risk for AF in hypertensive patients with LVH. Our data suggest that alcohol intake above this level may be marginally deleterious, while no effect of smoking on risk of AF was detected in hypertensive patients with LVH.

  • Comparison of benazepril plus amlodipine or hydrochlorothiazide in high-risk patients with hypertension and coronary artery disease
  • 2013
  • Ingår i: The American journal of cardiology. - 1879-19130002-9149. ; 112:2, s. 255-9
  • Tidskriftsartikel (refereegranskat)abstract
    • Combination therapy with benazepril 40 mg and amlodipine 10 mg (B+A) has been shown to be more effective than benazepril 40 mg and hydrochlorothiazide (HCTZ) 25 mg (B+H) in reducing cardiovascular (CV) events in high-risk patients with stage 2 hypertension with similar blood pressure reductions. In the present post hoc analysis, we evaluated whether B+A is more effective than B+H for reducing CV events in patients with known coronary artery disease (CAD) at baseline in a subgroup analysis of the Avoiding Cardiovascular events through COMbination therapy in Patients LIving with Systolic Hypertension (ACCOMPLISH) study. The main trial randomized 11,506 patients. Of those, 5,744 received B+A and 5,762 received B+H. Of the 11,506 patients, 5,314 (46%) were classified as having CAD at baseline. The mean patient follow-up period was 35.7 months for the B+A group and 35.6 months for the B+H group. The primary end point was the interval to the first event of composite CV morbidity and mortality. At baseline, significant differences were present between the 5,314 with CAD and the 6,192 without CAD. The patients with CAD had a lower systolic blood pressure and heart rate, a lower incidence of diabetes, and greater incidence of dyslipidemia. However, no baseline differences were found between the randomized B+A and B+H groups. In the patients with CAD, an 18% reduction occurred in the hazard ratio for CV events (primary end point) with B+A versus B+H (p = 0.0016). In a prespecified secondary analysis of the composite end point, including only CV death, myocardial infarction, and stroke, the hazard ratio in the patients with CAD was reduced by 25% (p = 0.0033) in the B+A group compared with the B+H group. B+A was more effective than B+H at comparable blood pressure reductions for reducing CV events in patients, regardless of the presence of CAD. In conclusion, our findings suggest that the combination of B+A should be preferentially used for older patients with high-risk, stage 2 hypertension.

  • Renal outcomes with different fixed-dose combination therapies in patients with hypertension at high risk for cardiovascular events (ACCOMPLISH): a prespecified secondary analysis of a randomised controlled trial
  • 2010
  • Ingår i: Lancet. - 1474-547X0140-6736. ; 375:9721, s. 1173-81
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The Avoiding Cardiovascular Events through Combination Therapy in Patients Living with Systolic Hypertension (ACCOMPLISH) trial showed that initial antihypertensive therapy with benazepril plus amlodipine was superior to benazepril plus hydrochlorothiazide in reducing cardiovascular morbidity and mortality. We assessed the effects of these drug combinations on progression of chronic kidney disease. METHODS: ACCOMPLISH was a double-blind, randomised trial undertaken in five countries (USA, Sweden, Norway, Denmark, and Finland). 11 506 patients with hypertension who were at high risk for cardiovascular events were randomly assigned via a central, telephone-based interactive voice response system in a 1:1 ratio to receive benazepril (20 mg) plus amlodipine (5 mg; n=5744) or benazepril (20 mg) plus hydrochlorothiazide (12.5 mg; n=5762), orally once daily. Drug doses were force-titrated for patients to attain recommended blood pressure goals. Progression of chronic kidney disease, a prespecified endpoint, was defined as doubling of serum creatinine concentration or end-stage renal disease (estimated glomerular filtration rate <15 mL/min/1.73 m(2) or need for dialysis). Analysis was by intention to treat (ITT). This trial is registered with ClinicalTrials.gov, number NCT00170950. FINDINGS: The trial was terminated early (mean follow-up 2.9 years [SD 0.4]) because of superior efficacy of benazepril plus amlodipine compared with benazepril plus hydrochlorothiazide. At trial completion, vital status was not known for 143 (1%) patients who were lost to follow-up (benazepril plus amlodipine, n=70; benazepril plus hydrochlorothiazide, n=73). All randomised patients were included in the ITT analysis. There were 113 (2.0%) events of chronic kidney disease progression in the benazepril plus amlodipine group compared with 215 (3.7%) in the benazepril plus hydrochlorothiazide group (HR 0.52, 0.41-0.65, p<0.0001). The most frequent adverse event in patients with chronic kidney disease was peripheral oedema (benazepril plus amlodipine, 189 of 561, 33.7%; benazepril plus hydrochlorothiazide, 85 of 532, 16.0%). In patients with chronic kidney disease, angio-oedema was more frequent in the benazepril plus amlodipine group than in the benazepril plus hydrochlorothiazide group. In patients without chronic kidney disease, dizziness, hypokalaemia, and hypotension were more frequent in the benazepril plus hydrochlorothiazide group than in the benazepril plus amlodipine group. INTERPRETATION: Initial antihypertensive treatment with benazepril plus amlodipine should be considered in preference to benazepril plus hydrochlorothiazide since it slows progression of nephropathy to a greater extent. FUNDING: Novartis.

  • The Diabetes Subgroup Baseline Characteristics of the Avoiding Cardiovascular Events Through Combination Therapy in Patients Living With Systolic Hypertension (ACCOMPLISH) Trial
  • 2008
  • Ingår i: Journal of the CardioMetabolic Syndrome. - 1559-4564. ; 3:4, s. 229-233
  • Tidskriftsartikel (refereegranskat)abstract
    • The Avoiding Cardiovascular Events Through Combination Therapy in Patients Living With Systolic Hypertension (ACCOMPLISH) trial is the first cardiovascular outcome trial designed to compare initial use of 2 different fixed-dose antihypertensive regimens, benazepril plus hydrochlorothiazide vs benazepril plus amlodipine, on cardiovascular end points in hypertensive patients at high cardiovascular risk secondary to previous major events or presence of diabetes mellitus (DM). Of the 11,464 patients, 60.4% had DM. Compared with non-DM patients, DM patients were less likely to have previous myocardial infarctions (15% vs 37%) or strokes (8% vs 21%). Those with DM were more likely to be female (43% vs 34%), black (15% vs 8%), overweight (body mass index, 32 vs 29 kg/m(2)). At baseline, DM patients were more likely to have the metabolic syndrome, manifested by higher levels of fasting glucose (145 vs 101 mg/dL) and triglycerides (178 vs 150 mg/dL) and slightly lower high-density lipoprotein cholesterol values (48 vs 51 mg/dL) compared to the non-DM cohort. Although estimated glomerular filtration rate (80 vs 76 mL/min/1.73 m(2)) was similar in the DM and non-DM groups, presence of both albuminuria (8.7% vs 3.5%) and microalbuminuria (29% vs 20%) were more prevalent in the DM group. After 6 months of treatment, blood pressure control rates (<140/90 mm Hg) using blinded data (both therapeutic groups combined) for DM demonstrated that 42.8% of DM patients had blood pressure levels <130/80 mm Hg. ACCOMPLISH will provide valuable guidance on optimizing treatment strategies in hypertensive patients at high cardiovascular risk with and without DM.

  • Four-group classification of left ventricular hypertrophy based on ventricular concentricity and dilatation identifies a low-risk subset of eccentric hypertrophy in hypertensive patients
  • 2014
  • Ingår i: Circulation. Cardiovascular imaging. - 1942-00801941-9651. ; 7:3, s. 422-9
  • Tidskriftsartikel (refereegranskat)abstract
    • Background-Left ventricular hypertrophy (LVH; high LV mass [LVM]) is traditionally classified as concentric or eccentric based on LV relative wall thickness. We evaluated the prediction of subsequent adverse events in a new 4-group LVH classification based on LV dilatation (high LV end-diastolic volume [EDV] index) and concentricity (mass/end-diastolic volume [M/EDV](2/3)) in hypertensive patients. Methods and Results-In the Losartan Intervention for Endpoint Reduction (LIFE) echocardiography substudy, 939 hypertensive patients with measurable LVM at baseline were randomized to a mean of 4.8 years of losartan- or atenolol-based treatment. Patients with LVH (LVM/body surface area &gt;= 116 and &gt;= 96 g/m(2) in men and woman, respectively) were divided into 4 groups-concentric nondilated (increased M/EDV, normal EDV), eccentric dilated (increased EDV, normal M/EDV), concentric dilated (increased M/EDV and EDV), and eccentric nondilated (normal M/EDV and EDV)-and compared with patients with normal LVM. Time-varying LVH classes were tested for association with all-cause and cardiovascular mortality and a composite end point of myocardial infarction, stroke, heart failure, and cardiovascular death in multivariable Cox analyses. At baseline, the LVs were categorized as eccentric nondilated in 12%, eccentric dilated in 20%, concentric nondilated in 29%, concentric dilated in 14%, and normal LVM in 25%. Treatment changed the prevalence of 4 LVH groups to 23%, 4%, 5%, and 7%; 62% had normal LVM after 4 years. In time-varying Cox analyses, compared with normal LVM, those with eccentric dilated and both concentric nondilated and dilated LVH had increased risks of all-cause or cardiovascular mortality or the composite end point, whereas the eccentric nondilated group did not. Conclusions-Hypertensive patients with relatively mild LVH without either increased LV volume or concentricity have similar risk of all-cause mortality or cardiovascular events because hypertensive patients with normal LVM seem to be a low-risk group.

    • Background:Left ventricular hypertrophy [LVH, high left ventricular mass (LVM)] is traditionally classified as concentric or eccentric based on left ventricular relative wall thickness. We evaluated left ventricular systolic function in a new four-group LVH classification based on left ventricular dilatation [high left ventricular end-diastolic volume (EDV) index and concentricity (LVM/EDV(2/3))] in hypertensive patients.Methods and results:Nine hundred thirty-nine participants in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) echocardiography substudy had measurable LVM at enrolment. Patients with LVH (LVM/body surface area 116g/m(2) in men and 96g/m(2) in women) were divided into four groups; eccentric nondilated' (normal LVM/EDV and EDV), eccentric dilated' (increased EDV, normal LVM/EDV), concentric nondilated' (increased LVM/EDV with normal EDV), and concentric dilated' (increased LVM/EDV and EDV) and compared to patients with normal LVM. At baseline, 12% had eccentric nondilated, 20% eccentric dilated, 29% concentric nondilated, and 14% concentric dilated LVH, with normal LVM in 25%. Compared with the concentric nondilated LVH group, those with concentric dilated LVH had significantly lower pulse pressure/stroke index and ejection fraction; higher LVM index, stroke volume, cardiac output, left ventricular midwall shortening, left atrial volume and isovolumic relaxation time; and more had segmental wall motion abnormalities (all P&lt;0.05). Similar differences existed between patients with eccentric dilated and those with eccentric nondilated LVH (all P&lt;0.05). Compared with patients with normal LVM, the eccentric nondilated had higher LV stroke volume, pulse pressure/stroke index, Cornell voltage product and SBP, and lower heart rate and fewer were African-American (all P&lt;0.05).Conclusion:The new four-group classification of LVH identifies dilated subgroups with reduced left ventricular function among patients currently classified with eccentric or concentric LVH.

  • Sex-related difference in regression of left ventricular hypertrophy with antihypertensive treatment: the LIFE study
  • 2004
  • Ingår i: J Hum Hypertens. - 0950-9240. ; 18:6, s. 411-6
  • Tidskriftsartikel (refereegranskat)abstract
    • While left ventricular (LV) structure and function differ between hypertensive women and men, it remains unclear whether sex affects regression of LV hypertrophy with antihypertensive treatment. We analysed paired echocardiograms in 500 men and 347 women enrolled in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study at baseline and after 12 months of antihypertensive treatment with either losartan or atenolol. At enrollment, 177 women and 242 men were randomized to losartan-based treatment and 161 women and 247 men were randomized to atenolol-based treatment (sex difference=NS). After 12 months of antihypertensive treatment, blood pressure was lowered similarly in women (152/83 from 174/97 mmHg) and men (149/85 from 173/99 mmHg; both P<0.001, sex difference=NS), without significant change in body weight in either sex. Cardiac output and pulse pressure/stroke volume were equivalently reduced in both sexes (-0.2 vs -0.1 l/min and both -0.20 mmHg/ml/m(2), respectively; both P=NS). Absolute LV mass change after 12 months of antihypertensive treatment was greater in men than in women (-30 vs -24 g, P=0.01). However, after adjusting for baseline LV mass and randomized study treatment, LV mass reduction was greater in women than in men (-33 vs -23 g, P=0.001). LV mass regression was greater in women, by 8.0+/-2.8 g, after adjusting for baseline LV mass and randomized study treatment. After consideration of baseline LV mass and randomized study treatment, antihypertensive treatment regressed LV hypertrophy more in women. Further studies are needed to identify the mechanisms and prognostic implications of this sex-related difference.

  • Effects of atenolol or losartan on fibrinolysis and von Willebrand factor in hypertensive patients with left ventricular hypertrophy.
  • 2010
  • Ingår i: Clinical and applied thrombosis/hemostasis. - 1076-0296. ; 16:2, s. 146-152
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To compare the effects of the beta-blocker atenolol with the angiotensin receptor blocker (ARB) losartan on plasma tissue-type plasminogen activator (tPA) activity and mass concentration, plasminogen activator inhibitor-1 (PAI-1) activity, tPA/PAI-1 complex, and von Willebrand factor (VWF). DESIGN: A prespecified, explorative substudy in 22 patients with hypertension and left ventricular hypertrophy (LVH) performed within randomized multicenter, double-blind prospective study. RESULTS: After a median of 36 weeks of treatment, there were significant differences between the treatment groups, atenolol versus losartan, in plasma median levels of tPA mass (11.9 vs 7.3 ng/mL, P = .019), PAI-1 activity (20.7 vs 4.8 IU/mL, P = .030), and tPA/PAI-1 complex (7.1 vs 2.5 ng/mL, P = .015). In patients treated with atenolol, median levels of tPA mass (8.9-11.9 ng/mL, P = .021) and VWF (113.5%-134.3%, P = .021) increased significantly, indicating a change toward a more prothrombotic state. No significant changes occurred in the losartan group. CONCLUSION: Losartan treatment was associated with preserved fibrinolytic balance compared to a more prothrombotic fibrinolytic and hemostatic state in the atenolol group. These findings suggest different fibrinolytic and hemostatic responses to treatment in hypertensive patients with LVH.

  • Exercise and cardiovascular outcomes in hypertensive patients in relation to structure and function of left ventricular hypertrophy: the LIFE study
  • 2009
  • Ingår i: Eur J Cardiovasc Prev Rehabil. - 1741-8275. ; 16:2, s. 242-8
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Exercise lowers blood pressure and improves cardiovascular function, but little is known about whether exercise impacts cardiovascular morbidity and mortality independent of left ventricular hypertrophy (LVH) and LV geometry. DESIGN: Observational analysis of prospectively obtained echocardiographic data within the context of a randomized trial of antihypertensive treatment. METHODS: A total of 937 hypertensive patients with ECG LVH were studied by echocardiography in the Losartan Intervention For Endpoint reduction in hypertension study. Baseline exercise status was categorized as sedentary (never exercise), intermediate (<or=30 min twice/week), or physically active (>30 min twice/week). During 4.8-year follow-up, 105 patients suffered the primary composite endpoint of myocardial infarction (MI), stroke, or cardiovascular death. MI occurred in 39, stroke in 60, and cardiovascular death in 33 patients. RESULTS: Sedentary individuals (n = 212) had, compared with those physically active (n = 511), higher heart rate (P<0.001), weight (P<0.001), body surface area (P = 0.02), body mass index (P<0.001), LV mass (LVM, P = 0.04), LVM indexed for height or body surface area (P = 0.004); thicker ventricular septum (P = 0.012) and posterior wall (P = 0.016); and larger left atrium (P = 0.006). Systolic variables did not differ. In Cox regression analysis, physically active compared with sedentary patients had lower risk of primary composite endpoint [odds ratio (OR): 0.42, 95% confidence interval (CI): 0.26-0.68, P < 0.001], cardiovascular death (OR: 0.50, 95% CI: 0.22-0.1.10, NS), and stroke (OR: 0.26, 95% CI: 0.13-0.49, P < 0.001) without significant difference for MI (OR: 0.79, 95% CI: 0.35-1.75, NS) independent of systolic blood pressure, LVM index, or treatment. CONCLUSION: In hypertensive patients with LVH, physically active patients had improved prognosis for cardiovascular endpoints, mortality, and stroke that was independent of LVM.
