Abstract
Aim: The present study investigated the appearance and severity of atrial fibrillation (AF) and heart failure (HF) in 8,702 hypertensive patients with left ventricular hypertrophy (LVH) receiving antihypertensive treatment in a prospective trial.
Methods: Patients who had a history of AF or HF were not included, and the participants had sinus rhythm when they were randomly allocated to blinded study medication. Endpoints were adjudicated.
Results: Incident AF occurred in 679 patients (7.8%) and HF in 246 patients (2.8%) during 4.7 ± 1.1 years mean follow-up. Incident AF was associated with a > 4-fold increased risk of developing subsequent HF [hazards ratios (HRs) = 4.7; 95% confidence intervals (CIs), 3.1–7.0; P < 0.001] in multivariable Cox analyses adjusting for age, sex, race, randomized treatment, standard cardiovascular risk factors and incident myocardial infarction. The development of HF as a time-dependent variable was associated with a multivariable-adjusted 3-fold increase of the primary study endpoint (HRs = 3.11; 95% CIs, 1.52–6.39; P < 0.001) which was a composite of myocardial infarction, stroke or cardiovascular death. Incident HF was associated with a > 3-fold increased risk of developing subsequent AF (HRs = 3.3; 95% CIs, 2.3–4.9; P < 0.001). This development of AF was associated with a > 2-fold increase of the composite primary study endpoint in multivariable Cox analysis (HRs = 2.26; 95% CIs, 1.09–4.67; P = 0.028).
Conclusions: Incident atrial fibrillation and heart failure are associated with increased risk of the other in treated hypertensive patients with left ventricular hypertrophy. Such high-risk hypertensive patients who subsequently develop both atrial fibrillation and heart failure have particular high risk of composite myocardial infarction, stroke or cardiovascular death (ClinicalTrials.gov identifier: NCT00338260).

Abstract
OBJECTIVE Left ventricular hypertrophy is the most common marker of target organ damage in arterial hypertension. Electrocardiograms are typically performed to identify left ventricular hypertrophy. The aim of this study was to analyse the prognostic utility of other electrocardiographic abnormalities in patients with arterial hypertension, beyond ventricular hypertrophy. MATERIALS AND METHODS The study included 1003 patients older than 65years with arterial hypertension. We recorded risk factors, previous cardiovascular history and medical treatment and analysed various electrocardiographic abnormalities including the Sokolow-Lyon index, the Cornell index, ventricular overload and branch blocks. The study conducted a 2-year follow-up, recording the major cardiovascular events (mortality, myocardial infarction, stroke and hospitalisation for heart failure). RESULTS The study population's mean age was 72.9±5.8years, 47.5% of whom were men. During the follow-up, 13.9% of the patients experienced a major cardiovascular event. These patients were older, more often smokers and engaged in less physical exercise, without presenting differences in the antihypertensive therapy or blood pressure control. The ventricular overload pattern (HR: 1.93; 95%CI: 1.160-3.196; P=.011) and the complete left bundle branch block (HR: 2.27; 95%CI: 1.040-4.956; P=.040) behaved as independent electrocardiographic predictors of major cardiovascular events; however, left ventricular hypertrophy using the Sokolow and/or Cornell index did not behave as such. CONCLUSIONS For patients with hypertension, the presence in the baseline electrocardiogram of complete left bundle branch block or a pattern of ventricular overload identifies a population at increased cardiovascular risk.

Four-group classification of left ventricular hypertrophy based on ventricular concentricity and dilatation identifies a low-risk subset of eccentric hypertrophy in hypertensive patients.

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 ≥116 and ≥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.
