    • The early mitral flow deceleration time (DTE) is a prognostically validated marker of left ventricular diastolic dysfunction. It has been reported that the DTE is influenced by the loading conditions, which can vary during antihypertensive treatment. We hypothesized that normalization of the DTE for mitral peak E-velocity (mitral deceleration index [MDI]) might better predict incident cardiovascular (CV) events in hypertensive patients during treatment compared to DTE alone or other traditional indexes of diastolic function, such as the mitral E/A ratio. We evaluated 770 hypertensive patients with electrocardiogram findings of left ventricular hypertrophy (age 66 +/- 7 years; 42% women) enrolled in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) echocardiographic substudy. Echocardiographic examinations were performed annually for 5 years during intensive antihypertensive treatment. We examined the utility of the MDI at baseline and as a time-varying predictor of incident CV events. Of the 770 patients, 70 (9%) had CV events. The baseline MDI was positively associated with age and relative wall thickness and negatively associated with gender and heart rate (all p <0.01). Unadjusted Cox regression analysis showed a positive association between the baseline MDI and CV events (hazard ratio 1.21, 95% confidence interval 1.07 to 1.37, p = 0.002). In the time-varied Cox models, a greater in-treatment MDI was associated with a greater rate of CV events (hazard ratio 1.43, 95% confidence interval 1.05 to 1.93, p = 0.022), independently of the covariates. No significant association was found for in-treatment DTE or any of the prognostically validated indexes of diastolic function. In conclusion, in our population of patients with treated hypertension with electrocardiographic findings of left ventricular hypertrophy, the MDI independently predicted future CV events. Normalization of DTE for E velocity might be preferred to other traditional diastolic function indexes in evaluating diastolic function during antihypertensive treatment.

  • Are coronary revascularization and myocardial infarction a homogeneous combined endpoint in hypertension trials? The Losartan Intervention For Endpoint reduction in hypertension study
  • 2010
  • Ingår i: Journal of Hypertension. - 0263-6352 .- 1473-5598. ; 28:6, s. 1134-1140

    • OBJECTIVE: Construction of prognostically relevant endpoints for clinical trials in hypertension has increasingly included coronary revascularization with myocardial infarction (MI) as manifestations of coronary artery disease. However, whether coronary revascularization and MI predict other cardiovascular events similarly is unknown. METHODS: We examined risks of cardiovascular death, all-cause death, and stroke following MI or coronary revascularization in hypertensive patients with left ventricular hypertrophy (LVH) enrolled in the Losartan Intervention For Endpoint reduction in hypertension study (LIFE). We studied 9113 patients after excluding those who died within 7 days after MI or underwent coronary revascularization within 24 h after MI. RESULTS: In multivariate Cox regression adjusting for participating countries, time-varying systolic blood pressure, and Framingham risk score, hazard ratios for cardiovascular death, all-cause death, and stroke were, respectively, 4.5 (P<0.0001), 2.9 (P<0.0001), and 1.9 (P=0.003) in 321 patients with MI as first event. In similar models, coronary revascularization as first event (n=202) was not associated with increased risks of cardiovascular death, all-cause death, and stroke (P=0.06-0.86). CONCLUSION: During follow-up of hypertensive patients with LVH, occurrence of MI but not coronary revascularization as first cardiovascular event significantly increased risk of subsequent cardiovascular death, all-cause death, and stroke. In view of differences in prognostic implications, when the goal is to have a prognostically relevant composite endpoint for trials in hypertensive patients, caution should be used in combining coronary revascularization with MI.

  • Clinical impact of 'in-treatment' wall motion abnormalities in hypertensive patients with left ventricular hypertrophy : the LIFE study
  • 2008

    • OBJECTIVES: Left ventricular systolic wall motion abnormalities have prognostic value. Whether wall motion detected by serial echocardiographic examinations predicts prognosis in hypertensive patients with left ventricular hypertrophy (LVH) without clinically recognized atherosclerotic disease has, however, never been investigated. We examined whether 'in-treatment' wall motion abnormalities predicted outcome in the Losartan Intervention For Endpoint (LIFE) reduction in hypertension echocardiographic substudy.METHODS: We studied 749 patients without coronary artery disease, myocardial infarction (MI), or stroke history. Echocardiographic segmental wall motion abnormalities at baseline and annual re-evaluations ('as time-varying covariate') were examined in relation to endpoints (cardiovascular mortality, MI, stroke, and hospitalized heart failure). Adjusted Cox regression was used to analyze the primary composite endpoint of cardiovascular death, MI, or stroke and, separately, for fatal and nonfatal MI and hospitalized heart failure.RESULTS: During a mean follow-up of 4.8 years, an event was recorded in 67 (9%) patients. In Cox models after adjusting for age, gender, treatment, blood pressure lowering, and serial change of left ventricular mass index, 'in-treatment' segmental wall motion abnormalities were associated with subsequent composite endpoint [hazard ratio = 2.1, 95% confidence interval (CI) 1.1-3.8; P = 0.019] and MI [hazard ratio = 3.7 (1.5-8.9); P = 0.004].CONCLUSION: In hypertensive patients with LVH and no history of cardiovascular disease, 'in-treatment' left ventricular wall motion abnormalities are associated with increased likelihood of subsequent cardiovascular events independent of age, gender, blood pressure lowering, treatment modality, and in-treatment left ventricular mass index.

    • Objective To evaluate whether lower stroke volume during antihypertensive treatment is a predictor of cardiovascular events independent of left ventricular geometric pattern. Methods The association between left ventricular stroke volume and combined cardiovascular death, stroke and myocardial infarction, the prespecified primary study endpoint, was assessed in Cox regression analysis using data from baseline and annual follow-up visits in 855 patients during 4.8 years of randomized losartan-based or atenolol-based treatment in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) echocardiography substudy. Results During follow-up, a total of 91 primary endpoints occurred. At baseline, lower left ventricular stroke volume was associated with smaller body size, female sex, lower left ventricular mass and stress-corrected midwall shortening, higher relative wall thickness and total peripheral resistance, more concentric left ventricular geometry and impaired diastolic relaxation (all P<0.01). Baseline stroke volume did not predict outcome. However, in time-varying multivariable Cox regression analysis, lower in-treatment left ventricular stroke volume indexed for height(2.04) was associated with higher risk of cardiovascular events {hazard ratio 1.69 per 1 SD (6 ml/m(2.04)) lower stroke volume [95% confidence interval (CI) 1.35-2.11], P<0.001} independent of in-treatment left ventricular mass and concentric geometry and in a secondary model also independent of stress-corrected midwall shortening, impaired diastolic relaxation, heart rate, new-onset atrial fibrillation and study treatment [hazard ratio 1.46 per 1 SD (6 ml/m(2.04)) lower stroke volume (95% CI 1.13-1.88)]. Conclusion Assessment of in-treatment left ventricular stroke volume may reflect cardiac and vascular remodeling and impairment and, hence, adds information on cardiovascular risk in treated hypertensive patients beyond assessment of left ventricular structure alone.

    • Aortic valve stenosis (AS) is the third most common cardiovascular disease. The prevalence of both AS and arterial hypertension increases with age, and the conditions therefore often co-exist. Co-existence of AS and arterial hypertension is associated with higher global left ventricular (LV) pressure overload, more abnormal LV geometry and function, and more adverse cardiovascular outcome. Arterial hypertension may also influence grading of AS, leading to underestimation of the true AS severity. Current guidelines suggest re-assessing patients once arterial hypertension is controlled. Management of arterial hypertension in AS has historically been associated with prudence and concerns, mainly related to potential adverse consequences of drug-induced peripheral vasodilatation combined with reduced stroke volume due to the fixed LV outflow obstruction. Current evidence suggests that patients should be treated with antihypertensive drugs blocking the renin-angiotensin aldosterone system, adding further drug classes when required, to achieve similar target blood pressure values as in hypertensive patients without AS. The introduction of trans-catheter aortic valve implantation has revolutionized the management of patients with AS, but requires proper blood pressure management during and following valve replacement. The purpose of this document is to review the recent evidence and provide practical expert advice on management of hypertension in patients with AS.

    • Neither losartan- nor atenolol-based antihypertensive regimens could prevent the progression of aortic valve (AV) sclerosis in elderly, high-risk hypertensive patients, and the regression of AV sclerosis did not translate into reduced cardiovascular risk.

  • Electrocardiographic characteristics and metabolic risk factors associated with inappropriately high left ventricular mass in patients with electrocardiographic left ventricular hypertrophy: the LIFE Study
  • 2007
  • Ingår i: J Hypertens. - 0263-6352. ; 25:5, s. 1079-85
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: To investigate electrocardiographic (ECG) and metabolic abnormalities associated with left ventricular (LV) mass inappropriately high for workload and body size (termed 'inappropriate left ventricular mass'; ILVM) in hypertensive patients with ECG left ventricular hypertrophy (LVH). METHODS: In patients enrolled in the Losartan Intervention for Endpoint Reduction (LIFE) Echocardiographic Substudy, LV structure and functions were assessed by echocardiography; Sokolow-Lyon and Cornell voltage, QRS duration, Cornell voltage-duration product and ST strain pattern in leads V5-V6 were evaluated on standard ECG tracings. ILVM was defined as observed LV mass greater than 128% of that predicted by sex, body size and stroke work. RESULTS: In univariate analysis, compared with subjects with appropriate LV mass (n = 593), ILVM (n = 348) was associated with older age, diabetes, higher body mass index, lower systolic blood pressure, higher serum creatinine and urinary albumin/creatinine levels, higher LV mass index and greater prevalence of wall motion abnormalities (all P < 0.05). ILVM was associated with higher Cornell voltage and voltage-duration product but not higher Sokolow-Lyon voltage, with longer QRS and higher prevalences of ECG ST strain and echocardiographic wall motion abnormalities, independent of covariates including echocardiographically defined LVH or LV geometry. In separate logistic models, the likelihood of ILVM was significantly related to prolonged QRS duration, higher Cornell voltage, and greater Cornell voltage-duration independently (all P < 0.01). CONCLUSION: In hypertensive patients with ECG LVH, ILVM was associated with prolonged QRS duration and higher Cornell voltage, with ECG ST strain pattern, and with echocardiographic wall motion abnormalities independent of traditionally defined LVH.

  • Angiotensin II receptor blockade reduces new-onset atrial fibrillation and subsequent stroke compared to atenolol: the Losartan Intervention For End Point Reduction in Hypertension (LIFE) study
  • 2005
  • Ingår i: J Am Coll Cardiol. - 0735-1097. ; 45:5, s. 712-9
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: This study was designed to evaluate whether different antihypertensive treatment regimens with similar blood pressure reduction have different effects on new-onset atrial fibrillation (AF). BACKGROUND: It is unknown whether angiotensin II receptor blockade is better than beta-blockade in preventing new-onset AF. METHODS: In the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study 9,193 hypertensive patients and patients with electrocardiogram-documented left ventricular hypertrophy were randomized to once-daily losartan- or atenolol-based antihypertensive therapy. Electrocardiograms were Minnesota coded centrally, and 8,851 patients without AF by electrocardiogram or history, who were thus at risk of developing AF, were followed for 4.8 +/- 1.0 years. RESULTS: New-onset AF occurred in 150 patients randomized to losartan versus 221 to atenolol (6.8 vs. 10.1 per 1,000 person-years; relative risk 0.67, 95% confidence interval [CI] 0.55 to 0.83, p < 0.001) despite similar blood pressure reduction. Patients receiving losartan tended to stay in sinus rhythm longer (1,809 +/- 225 vs. 1,709 +/- 254 days from baseline, p = 0.057) than those receiving atenolol. Moreover, patients with new-onset AF had two-, three- and fivefold increased rates, respectively, of cardiovascular events, stroke, and hospitalization for heart failure. There were fewer composite end points (n = 31 vs. 51, hazard ratio = 0.60, 95% CI 0.38 to 0.94, p = 0.03) and strokes (n = 19 vs. 38, hazard ratio = 0.49, 95% CI 0.29 to 0.86, p = 0.01) in patients who developed new-onset AF in the losartan compared to the atenolol treatment arm of the study. Furthermore, Cox regression analysis showed that losartan (21% risk reduction) and new-onset AF both independently predicted stroke even when adjusting for traditional risk factors. CONCLUSIONS: Our novel finding is that new-onset AF and associated stroke were significantly reduced by losartan- compared to atenolol-based antihypertensive treatment with similar blood pressure reduction.
