- BackgroundThe extent to which adult height, a biomarker of the interplay of genetic endowment and early-life experiences, is related to risk of chronic diseases in adulthood is uncertain.MethodsWe calculated hazard ratios (HRs) for height, assessed in increments of 6.5 cm, using individual-participant data on 174 374 deaths or major non-fatal vascular outcomes recorded among 1 085 949 people in 121 prospective studies.ResultsFor people born between 1900 and 1960, mean adult height increased 0.5-1 cm with each successive decade of birth. After adjustment for age, sex, smoking and year of birth, HRs per 6.5 cm greater height were 0.97 (95% confidence interval: 0.96-0.99) for death from any cause, 0.94 (0.93-0.96) for death from vascular causes, 1.04 (1.03-1.06) for death from cancer and 0.92 (0.90-0.94) for death from other causes. Height was negatively associated with death from coronary disease, stroke subtypes, heart failure, stomach and oral cancers, chronic obstructive pulmonary disease, mental disorders, liver disease and external causes. In contrast, height was positively associated with death from ruptured aortic aneurysm, pulmonary embolism, melanoma and cancers of the pancreas, endocrine and nervous systems, ovary, breast, prostate, colorectum, blood and lung. HRs per 6.5 cm greater height ranged from 1.26 (1.12-1.42) for risk of melanoma death to 0.84 (0.80-0.89) for risk of death from chronic obstructive pulmonary disease. HRs were not appreciably altered after further adjustment for adiposity, blood pressure, lipids, inflammation biomarkers, diabetes mellitus, alcohol consumption or socio-economic indicators.ConclusionAdult height has directionally opposing relationships with risk of death from several different major causes of chronic diseases.

- Background-The prognostic impact of ECG left ventricular strain and left ventricular hypertrophy (LVH) in asymptomatic aortic stenosis is not well described. Methods and Results-Data were obtained in asymptomatic patients randomized to simvastatin/ezetimibe combination versus placebo in the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) study. Primary end point was the first of myocardial infarction, nonhemorrhagic stroke, heart failure, aortic valve replacement, or cardiovascular death. The predictive value of ECG left ventricular strain (defined as T-wave inversion in leads V(4) through V(6)) and LVH, assessed by Sokolow-Lyon voltage criteria (R(V5-6) +/- S(V1) >= 35 mV) and Cornell voltage-duration criteria {[RaVL + S(V3) + (6 mV in women)] x QRS duration >= 2440 mV.ms}, was evaluated by adjustment for other prognostic covariates. A total of 1533 patients were followed for 4.3 +/- 0.8 years (6592 patient-years of follow-up), and 627 cardiovascular events occurred. ECG strain was present in 340 patients (23.6%), with LVH by Sokolow-Lyon voltage in 260 (17.1%) and by Cornell voltage-duration product in 220 (14.6%). In multivariable analyses, ECG left ventricular strain was associated with 3.1-fold higher risk of in-study myocardial infarction (95% confidence interval, 1.4-6.8; P = 0.004). Similarly, ECG LVH by both criteria predicted, compared with no ECG LVH, 5.8-fold higher risk of heart failure (95% confidence interval, 2.0 -16.8), 2.0-fold higher risk of aortic valve replacement (95% confidence interval, 1.3-3.1; both P = 0.001), and 2.5-fold higher risk of a combined end point of myocardial infarction, heart failure, or cardiovascular death (95% confidence interval, 1.3-4.9; P = 0.008). Conclusions-ECG left ventricular strain and LVH were independently predictive of poor prognosis in patients with asymptomatic aortic stenosis.

- Objectives The aim of the study was to examine the predictive value of QRS duration and morphology during watchful waiting in asymptomatic patients with aortic stenosis (AS). Background QRS duration and morphology are associated with poor prognosis in many different populations, but the predictive value, particularly of the risk of sudden cardiac death (SCD), in asymptomatic patients with AS has not been well studied. Methods Data were obtained in asymptomatic AS patients randomized to simvastatin/ezetimibe combination versus placebo in the SEAS (Simvastatin and Ezetimibe in Aortic Stenosis) study. The impact of QRS duration, evaluated as a categorical variable of <85 ms versus 85 to 99 ms and >= 100 ms (excluding bundle branch block [BBB]) and QRS morphology in those with BBB, on cardiovascular morbidity and mortality was assessed by adjusting for clinical and echocardiographic covariates. Results QRS data were available in 1,542 patients who were followed for a mean of 4.3 +/- 0.8 years (6,631 patient-years of follow-up). There were 68 cardiovascular deaths (4.6%), including 27 SCDs (1.8%). QRS duration was <85 ms in 900 patients (58.4%), 85 to 99 ms in 396 (25.7%), >= 100 ms in those without BBB in 144 (9.3%), and 102 (6.6%) in those with BBB. In multivariable analyses, those with QRS duration >= 100 ms had, compared with those with QRS duration <85 ms, a 5-fold higher risk of SCD (95% confidence interval: 1.8 to 13.7, p = 0.002) and a 2.5-fold higher risk of cardiovascular death (95% confidence interval: 1.2 to 5.1, p = 0.01). Conclusions QRS duration and morphology in asymptomatic patients with AS are independently associated with a poor prognosis, particularly the risk of SCD.
